- Figure 2 schematically shows a means for implementing a method of manufacturing a metal-plastic or biplastic product, mainly a closure cap for a bottle, according to the invention, after feeding the molten plastic, a longitudinal section.
- FIG. 1 schematically shows the initial state of the means for implementing the method of manufacturing a metal-plastic or biplastic product, preferably a closure cap for a bottle of the invention.
- the inventive method relates to the manufacture of products having a bucket shape, mainly a bottle cap.
- the inventive method includes the manufacture of metal or plastic blanks 1 of the outer shell of the closure cap.
- the invention provides for the possibility of manufacturing a blank 1 of the outer shell of the closure cap from a material consisting of layers of different metals or from a composite based on metal and plastic.
- the inventive method is suitable for forming a closure cap, the outer shell of which is made only of plastic, namely hard plastic, for example polycarbonate, which can be deformed without breaking, including during partial heat transfer from the molten plastic used in the manufacture of the inner element of the closure cap.
- the preparation of the blank 1 of the outer shell of the closure cap is carried out by currently known techniques, namely, for example, stamping, rolling.
- a predetermined relief 3 is performed on the inner surface of the side and / or end walls of the mold 2.
- a punch 4 is introduced into said blank 1 with the formation of an annular gap 5 between the surface of the punch 4 and the inner surface of the blank 1.
- the punch 4 on the surface of the punch 4 also perform a given relief.
- the molten plastic 6 is fed into the formed gap 5 under pressure, the entire gap 5 is filled with it, and as a result, the workpiece 1 is pressed against the inner surface of the mold 2. In this case, the gap 5 increases and the increased volume of the gap 5 is filled with the molten plastic.
- plastic 6 it is possible to use, for example, thermosetting plastics based on phenol-formaldehyde resins, polyester resins, epoxy resins, urea-formaldehyde resins; or thermoplastic plastics, for example, based on polyolefins, polyvinyl chloride, polystyrene.
- the supply of molten plastic 6 to the gap 5 can be carried out through a channel 7 made in the punch 4.
- the invention provides for the possibility of feeding the molten plastic 6 into the gap 5 through a channel formed in the mold 2.
- an inner plastic element 8 (FIG. 2) of the closure cap is formed in the blank 1 of the outer shell of the closure cap. Moreover, on the outer surface of the walls of the formed inner plastic element 8 form a relief that is identical in configuration and size to a given relief on the surface of the punch 4. The configuration and wall thickness of the formed inner plastic element 8 corresponds to the configuration and thickness of the annular gap 5 (Fig. L).
- the formation of the inner element 8 (FIG. 2) is carried out, the element 8 is placed in the blank 1 of the outer shell of the closure cap and the element 8 is fixed in the blank 1.
- the outer shell 1 of the closure cap may be made, for example, of polycarbonate, and the inner element 8 may be made of a different type of plastic, for example, linear polyethylene.
- the inner plastic element 8 of the obtained biplastic closure cap may exceed the size of the open part 9 of the outer shell of the closure cap, namely, the inner plastic element 8 may have a barrel-shaped or cone shape with an extension to the end face of the outer shell of the closure cap or any other shape including non-concentric.
- a relief is formed that is identical in configuration and size to the given relief on the inner surface of the side and / or end walls of the mold 2.
- the plastic melt 6 is supplied to the gap 5 under pressure, depending on the fluidity of the used polymeric material, the size of the gap, the ductility of the material of the outer shell, the height and width of the formed relief of the outer shell.
- the specific value of the pressure when feeding the plastic melt depends on the material from which the preform 1 is made, and the thickness of its walls. For example, when using a workpiece 1 made of aluminum sheet 0.24 mm thick, and having a wall thickness of 1.2 mm, it is enough to feed the plastic melt under a pressure of 5-30 Atm so that the walls of the workpiece 1 deform in accordance with the configuration of the walls of the mold 2 and its relief sections 3 and the desired relief of the outer shell of the closure cap has been achieved, that is, the formation of the outer shell of the closure cap.
- the predetermined relief in the process of said formation of the outer shell of the closure cap in the mold 2, can be formed on the side wall 10 (FIG. 2) and / or on the end wall 11 of the outer shell of the closure cap, for example, forming ribs , relief graphic elements, alphabetic, digital designations.
- a given relief can be formed only on the outer surface of the workpiece l (Fig. 1). However, depending on the height and radius of conjugation of the relief sections 3 on the walls of the mold 2, their configuration and the pressure of the plastic melt supply, it is possible to deform both the outer and inner surfaces of the walls of the metal outer shell of the product, including the formation of through slots (in Fig. shown) the walls of the shell of the product.
- the blank 1 is pressed against the inner surface of the mold 2, in the relief of which, according to the invention, at least one section is provided for deformation of the material blanks of the outer shell exceeding the yield strength of this material.
- a predetermined inner plastic element 8 (FIG. 2) and forming the outer shell the closure cap adhere the outer shell of the closure cap and its plastic element, achieve mechanical fixation of the plastic element in the specified shell of the closure cap, including by performing specified reliefs both on the walls of the outer shell and on the walls of the inner plastic element, providing the adhesion of the elements products in both axial and radial directions.
- a feature of the proposed method is that in the process of a single technological stage it is possible to additionally create a plastic element - a duplicating plastic shell on the outer surface of the outer shell of the product. For this, a space is formed between the outer surface of the workpiece 1 and the inner surface of the mold 2 (not shown in FIG.). Through the cuts of the outer shell create through the slots, then the plastic melt, supplied under pressure into the annular gap between the surface of the punch 4 and the inner surface of the workpiece 1, is sent through the through cuts of the outer shell into the above-mentioned space between the outer surface of the workpiece 1 and the inner surface of the mold 2. Thus, after cooling, at least a fragment of the plastic shell of the product is formed on the outer surface of the workpiece of the outer shell, which is integral with the outside plastic element.
- the proposed method provides a simplification of the manufacturing technology of a metal-plastic or biplastic product, if possible, to complicate the design of the target product with respect to the configuration of its polymer inner element.
- the proposed method allows for one technological stage to produce an internal polymer element of any desired configuration, place it in a metal or plastic billet of the outer shell of the product, form a predetermined shape of the target product and reliably fix one element of the target product relative to its other element.
- the invention will find application in the manufacture of bucket-shaped products having a shell made of metal or plastic, and an internal element made of plastic, in particular, the invention will find application in the formation of a closure cap for a bottle.
