Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
In the related art, the data line overmold 140 is a housing for protecting the data line plug 170, the plug of the data line is generally flat, that is, the width of the plug is greater than the thickness, and a portion of the data line with a safety size has a clear requirement on the thickness of the data line overmold 140, for example, the maximum thickness of the data line overmold 140 is required to be not more than 6.5mm/6.25mm by the association such as USB-IF (USB Implementers Forum, USB developer Forum)/MFI (male for iPhone, apple certification), which makes the requirement on the injection precision of the data line overmold 140 in the thickness direction higher than the requirement on the injection precision in the width direction.
As shown in fig. 1-2, the data line is usually molded by single-side feeding, the pressure during injection molding acts on one side of the data line plug 170, the data line plug 170 is likely to move in the mold cavity due to uneven stress, which causes severe glue shortage after injection molding of the data line outer mold 140, and the defect is difficult to overcome even by machine adjustment during production and manufacturing.
As shown in fig. 3 to 5, a common solution to this defect is to change an outer mold into a mold with two sides for feeding simultaneously, and the two sides for feeding simultaneously can solve the phenomenon of unbalanced pressure on the two sides of the data line plug 170 during injection molding to a certain extent, but for some data line products, for example, a data line product with a length of the data line plug 170 being greater than 30mm or a thickness of the data line plug 170 being less than 0.8mm, or a situation that the data line plug 170 shakes in a mold cavity to cause a glue shortage after the injection molding of the data line outer mold 140, in this situation, a thimble is usually added in the mold, and the thimble needs to be used to press the data line plug 170 during the injection molding, so that a thimble hole is formed on the surface of the data line outer mold 140 after injection molding, the integrity of the appearance is damaged, and the waterproof performance of the data line plug 170 is reduced. In addition, for products using ultra-soft wires or wires in an empty tube state, the use of a die with two sides fed simultaneously can not avoid the phenomenon of glue shortage caused by wrinkling of the wires in the forming process of the data wire external die 140.
As shown in fig. 6 to 10, a first aspect of the embodiments of the present application provides an injection mold 100, and the injection mold 100 is used for injecting a data line outer mold 140. A cavity (not shown) is formed in the injection mold 100, the cavity is used for accommodating the data line plug 170, an injection port 110 is formed in the outer surface of the injection mold 100, and a first feed port 120 and a second feed port 130 are formed in the top wall of the cavity and the bottom wall of the cavity respectively. The first feed opening 120 may include a single opening or may include a plurality of openings; the second feed opening 130 may include a single opening or may include a plurality of openings. The injection port 110 may be in communication with the first feed opening 120 and the second feed opening 130 via a pipe, or may be in communication with a connecting passage formed in the injection mold 100. The injection port 110 may be one, and one injection port 110 is connected to both the first feed port 120 and the second feed port 130. The number of the injection molding openings 110 may be two, and the two injection molding openings 110 are respectively and correspondingly communicated with the first feed opening 120 and the second feed opening 130. The number of the injection ports 110 may be more, and a plurality of injection ports 110 are correspondingly communicated with the first feed port 120 and/or the second feed port 130.
When the data line plug 170 is subjected to injection molding, an injection molding raw material is injected into the injection molding port 110, the injection molding raw material is injected into the cavity after passing through the first feed port 120, and is firstly contacted with the bottom wall of the cavity, the top wall of the cavity, the bottom wall of the data line plug 170 and the top wall of the data line plug 170, then the injection molding raw material flows between the side wall of the cavity and the side wall of the data line plug 170 and fills the whole cavity, the injection molding raw material partially covers the data line plug 170 to form a data line outer mold 140, and the mold can be removed after the injection molding raw material is cooled and molded. The injection molding material is a thermoplastic plastic material, such as PC (Polycarbonate), and different injection molding materials require different injection temperatures and injection pressures, and the specific injection temperatures and injection pressures can be determined according to the selected injection molding material.
The injection mold 100 of the embodiment of the application can avoid the situation that the data line plug 170 shakes in the mold cavity to cause the glue shortage after injection molding as far as possible, the injection molding effect of the upper and lower surfaces can be guaranteed without increasing a thimble in the mold, and the situation that the glue shortage after molding is caused by shaking of a product in the mold cavity when the three-plate mold is used for molding is solved. In addition, for the product using the ultra-soft wire or the wire in the hollow pipe state, the pressure of the feeding materials at the same time is equal when the data wire outer die 140 is formed, so that the wire is prevented from being bent under stress, and the phenomenon of glue shortage caused by wrinkling in the forming process of the data wire outer die 140 is reduced.
To sum up, because first feed inlet 120 and second feed inlet 130 set up respectively in the roof and the diapire of die cavity, the raw materials of moulding plastics can be followed two upper and lower direction and fed simultaneously, and the pressure of feeding is the same, and the circumstances of aversion from top to bottom can not appear basically in data line plug 170, and the raw materials of moulding plastics can be preferential cladding data line plug 170's upper surface and lower surface, avoids data line plug 170's upper surface and lower surface to appear the condition of scarce glue. For the side surface of the data line plug 170, since the dimension of the data line outer mold 140 in the width direction is relatively loosely limited, the data line outer mold 140 may have a thicker injection molding layer in the width direction, and even if the data line plug 170 is shifted in the width direction, the situation of glue shortage is not likely to occur. Meanwhile, the appearance integrity of the data wire outer die 140 can be improved, the production yield of the data wire is improved, and the production cost is reduced.
In some embodiments, the injection mold 100 may include a first mold and a second mold, which may be attached together or separated to facilitate the data line plug 170 to be taken out and put in. The first mould orientation the surface of second mould is provided with the first groove of moulding plastics, the second mould orientation the surface of first mould is provided with the second groove of moulding plastics, the first groove of moulding plastics with the second is moulded plastics the groove and is enclosed and form the die cavity, the diapire in the first groove of moulding plastics and the diapire in the second groove of moulding plastics are provided with respectively first feed inlet 120 reaches second feed inlet 130. In order to facilitate the alignment of the first mold and the second mold, the first mold and the second mold may be provided with a positioning hole and a positioning pin, respectively. Of course, the injection mold 100 may also be formed by combining more sub-molds, and only the sub-molds need to be surrounded to form a cavity. The injection port 110 may be disposed on the first mold, the second mold, or both the first mold and the second mold. It should be noted that the cavity is not only formed by enclosing the first injection groove and the second injection groove, but also can be formed in the first mold, and the second mold only plays a role in sealing the cavity. Or the cavity is arranged in the second mould, and the first mould only plays a role of sealing the cavity.
As shown in fig. 9, in some embodiments, the first feeding hole 120 is disposed at an edge of a bottom wall of the first injection groove (not shown), and the second feeding hole 130 is disposed at an edge of a bottom wall of the second injection groove (not shown). Generally, the joints of the data line outer die 140 and other parts are easily damaged, and injection molding is performed from the edges, so that the joints of the data line outer die 140 and other parts have a good injection molding effect. For example, the connection position of the data line plug 170 and the transmission line 180 is easily damaged, and at this time, the first feed opening 120 may be disposed at the joint of the data line plug 170 and the transmission line 180, so as to ensure the injection molding quality of the joint of the data line plug 170 and the transmission line 180, and improve the service life of the data line.
As shown in fig. 10, in some embodiments, the projection positions of the first feed opening 120 disposed in the first injection groove and the second feed opening 130 disposed in the second injection groove on the mold clamping surface coincide with each other. If the structure of the front and back surfaces of the data line plug 170 is the same, the injection molding quality of the front and back surfaces of the data line plug 170 can be kept consistent as much as possible, and the consistency of the injection molding quality is improved. If the front and back surfaces of the data line plug 170 have different structures, the positions of the first feed opening 120 and the second feed opening 130 can be adjusted according to actual conditions, so that the projection positions of the first feed opening 120 arranged in the first injection molding groove and the second feed opening 130 arranged in the second injection molding groove on the joint surface do not coincide with each other.
As shown in fig. 11 to 13, in some embodiments, a third feeding port 150 is disposed on a side wall of the cavity, specifically, the third feeding port 150 may be disposed on a side wall of the first injection molding groove, a side wall of the second injection molding groove, or both the side wall of the first injection molding groove and the side wall of the second injection molding groove, that is, a part of the third feeding port 150 is disposed on the side wall of the first injection molding groove, and another part is disposed on the side wall of the second injection molding groove. The injection port 110 is communicated with the third feeding port 150, and the third feeding port 150 may include a single opening or a plurality of openings. In some cases, the thicknesses of the left and right sides of the data line plug 170 required for injection molding may be different, and it is difficult for the injection molding material injected from the first feed opening 120 and the second feed opening 130 to fill the entire cavity, or even if the cavity can be filled, a large injection pressure is required. For this purpose, the third feeding port 150 may be provided at a side of the data line plug 170 requiring a thicker injection molding to ensure the injection molding quality of the side.
As shown in fig. 11 and 13, in some embodiments, a fourth feeding hole 160 is further disposed on the sidewall of the cavity, specifically, the fourth feeding hole 160 may be disposed on the sidewall of the first injection molding groove, the sidewall of the second injection molding groove, or both the sidewall of the first injection molding groove and the sidewall of the second injection molding groove, that is, a portion of the fourth feeding hole 160 is disposed on the sidewall of the first injection molding groove, and another portion is disposed on the sidewall of the second injection molding groove. The injection molding opening 110 is communicated with the fourth feeding opening 160, the fourth feeding opening 160 is opposite to the third feeding opening 150, and the fourth feeding opening 160 may include a single opening or a plurality of openings. The first feed inlet 120, the second feed inlet 130, the third feed inlet 150 and the fourth feed inlet 160 are all communicated with the injection molding opening 110, the pressures of the first feed inlet 120, the second feed inlet 130, the third feed inlet 150 and the fourth feed inlet 160 are the same, so that the pressures on the upper surface, the lower surface and the two side surfaces of the data line plug 170 are the same, the forces in all directions can be mutually offset, the data line outer die 140 can not be shifted basically during injection molding, the injection molding success rate of the data line outer die 140 is improved, and the injection molding speed is improved. The injection molding method has good injection molding success rate for objects with low rigidity and easy deformation, and reduces the possibility of glue shortage caused by deformation due to uneven stress in the injection molding process.
As shown in fig. 14, a second aspect of the embodiments of the present application provides a method for manufacturing a data line overmold 140, where the method for manufacturing the data line overmold 140 includes the following steps: placing the data line plug 170 in a cavity of the injection mold 100; injecting an injection raw material from an injection port 110 formed in an outer surface of the injection mold 100, so that the injection raw material is simultaneously injected into the cavity through a first feed port 120 formed in a top wall of the cavity and a second feed port 130 formed in a bottom wall of the cavity, thereby injecting the data line plug 170, and forming a data line outer mold 140 on an outer periphery of the data line plug 170.
In summary, since the injection molding material is injected into the cavity through the first feed opening 120 disposed on the top wall of the cavity and the second feed opening 130 disposed on the bottom wall of the cavity, the injection molding material can preferentially cover the upper surface and the lower surface of the data line plug 170, and the situation of glue shortage on the upper surface and the lower surface of the data line plug 170 is avoided.
In some embodiments, the injection molding material is injected from the first feed port 120 disposed at the top wall of the cavity and the second feed port 130 disposed at the bottom wall of the cavity at the same pressure. The same pressure of the injection molding raw materials can ensure that the stress on the upper surface and the stress on the lower surface of the data line plug 170 are the same, and the displacement of the data line plug 170 caused by the injection molding pressure is avoided.
In some embodiments, after the step of placing the data line plug 170 in the cavity of the injection mold 100, the method further includes: injecting injection raw materials from an injection port 110 formed in the outer surface of the injection mold 100, so that the injection raw materials are simultaneously injected into the cavity through a first feed port 120 formed in the top wall of the cavity, a second feed port 130 formed in the bottom wall of the cavity, and a third feed port 150 formed in the side wall of the cavity.
