Description

Take out and built-in lifter demoulding mechanism in the helmet translucent cover mould slide block

Technical field

The utility model relates in the helmet translucent cover mould slide block to be taken out and built-in lifter demoulding mechanism, belongs to the mould of plastics field.

Background technology

Adopt injection mold to produce plastic product, this product relates to the motorcycle helmet translucent cover, bright and clean, the clear-cut of the appearance requirement of helmet translucent cover; Good without shrink mark, warpage, cut, crackle, transparency; without defectives such as orange peel lines; and there are the structures such as tooth bar, gathering sill the product inside portion; existing processing mold adopts often puts die opening mechanism; the appearance quality of product is difficult to be guaranteed; ejecting product is difficult during the demoulding, causes tooth bar etc. to pull or deformation of products, has reduced the qualification rate of finished product.

Summary of the invention

The purpose of this utility model is the shortcoming that exists in order to overcome prior art; provide oblique top and thimble are set in a kind of slide block; realize the mechanism laterally eject, take out and built-in lifter demoulding mechanism in the helmet translucent cover mould slide block that requires with aspects such as the fineness of the Functional Requirement that guarantees the product product and product and transparencies.

Take out in the utility model helmet translucent cover mould slide block and the technical scheme of built-in lifter demoulding mechanism is: comprise compound plate and lower compound plate; connect solid plate under the upper compound plate; the mould pin is installed on the lower compound plate; face needle plate and end needle plate are set in the mould pin; on the mould pin moving platen is installed; the helmet translucent cover that moulding is arranged between moving platen and the solid plate; it is characterized in that installing on described needle plate and the end needle plate straight top I-shaped piece; on the I-shaped piece of straight top horizontal knock-pin is set; outer slide and inner slide are set on the moving platen; knock-pin is installed in the inner slide, at solid plate the slider locking piece is set, and Angle Pin is set in the latch segment; outer slide is shaped with slanting guide pillar hole; Angle Pin passes slanting guide pillar hole, at solid plate the locked mode pin is set, and is shaped with the locked mode hole on the inner slide; the locked mode pin passes the locked mode hole; also arrange first in the inner slide; the second and the 3rd oblique top arranges oblique-top sliding seat at moving platen, and the 3rd oblique top matches with oblique-top sliding seat.

The utility model discloses in a kind of helmet translucent cover mould slide block and take out and built-in lifter demoulding mechanism, during the demoulding, injection machine power drives moving platen and solid plate die sinking, in the time of die sinking, outer slide and inner slide are respectively under the drive of Angle Pin and locked mode pin, finished the action that slide block outwards slides and inwardly slides, the back-off of having finished the outer surface of product is loosed core and the demoulding action of the tooth bar of product inner surface, when inner slide inwardly slides, 3 oblique tops that arrange in the inner slide are finished the action of loosing core of gathering sill simultaneously, and the position of the relative oblique top of product changes, and product is without distortion; After the die sinking, push up on the top board, the straight top I-shaped piece on the top board drives the push rod ejecting product product in the inner slide, and product is with the deformation demoulding of minimum.The mechanism of loosing core in conjunction with and laterally ejecting inside and outside this programme adopts has effectively avoided distortion that product stripping produces, has pulled and damage, and guarantees product quality, reduces scrappage, enhances productivity.

The specific embodiment

The utility model relates in a kind of helmet translucent cover mould slide block to be taken out and built-in lifter demoulding mechanism; such as Fig. 1-shown in Figure 2; comprise compound plate 1 and lower compound plate 13; connect solid plate 2 under the upper compound plate; mould pin 10 is installed on the lower compound plate; face needle plate 11 and end needle plate 12 are set in the mould pin; moving platen 9 is installed on the mould pin; the helmet translucent cover 15 that moulding is arranged between moving platen and the solid plate; it is characterized in that installing on described needle plate 11 and the end needle plate 12 straight top I-shaped piece 16; on the I-shaped piece of straight top horizontal knock-pin 17 is set; outer slide 6 and inner slide 8 are set on the moving platen; knock-pin is installed in the inner slide 8; at solid plate 2 slider locking piece 4 is set; Angle Pin 5 is set in the latch segment; outer slide 6 is shaped with slanting guide pillar hole; Angle Pin passes slanting guide pillar hole; at solid plate 2 locked mode pin 7 is set; be shaped with the locked mode hole on the inner slide 8; the locked mode pin passes the locked mode hole; also arrange first in the inner slide 8; the second and the 3rd oblique top 18; 19; 20, at moving platen 9 oblique-top sliding seat 21, the three oblique tops 20 are set and match with oblique-top sliding seat 21.During the demoulding, injection machine power drives moving platen 9 and solid plate 2 die sinkings, during die sinking, moving platen 9 drives outer slide 6 and inner slide 8 moves downward, in this motion process, outer slide 6 is simultaneously outwards motion under the effect of Angle Pin 5, and also simultaneously inwardly motion under the effect of locked mode pin 7 of inner slide 8, finished simultaneously product---the back-off of the outer surface of helmet translucent cover is loosed core and the demoulding action of the tooth bar of product inner surface, when inner slide 8 inwardly slides, force three oblique tops 18 that are arranged on inner slide 8 inside, 19,20 finish the action of loosing core, the action of loosing core of three oblique tops is as follows respectively, when inner slide 8 inwardly moves, because the tail end of the first oblique top 18 and the second oblique top 19 contacts with the inside casing of solid plate 2 and can not inwardly move, can only do relative side-to-side movement in the inside of inner slide, deviate from back-off; And the 3rd oblique top 20 contacts and can not inwardly move with oblique-top sliding seat 21 equally, under the inner slide 8 inside dynamic actions that move, can only do relative side-to-side movement in inner slide inside, finishes loosing core of back-off.Three oblique tops are not only finished the action of loosing core of inner slide inside smoothly, and when inner slide inwardly moves, withstand product, prevent the product distortion that curves inwardly under the package power to inner slide.In order to guarantee to get product after the die sinking, product is not damaged by oblique top, guarantee the batch production that product is guaranteed both quality and quantity, we also are provided with respectively knock-pin 17(in two inner slides be the line position thimble), its action is as follows, after die sinking, top rod end face needle plate 11 and the end needle plate 12 of injection machine move upward, the face needle plate drives built-in straight top I-shaped piece 16 and also moves upward, the outwards motion under I-shaped piece 16 top I-shaped grooves in straight top drive of knock-pin 17 this moment, thereby ejecting product.The mechanism of loosing core in conjunction with and laterally ejecting inside and outside this programme adopts has effectively avoided distortion that product stripping produces, has pulled and damage, and guarantees product quality, reduces scrappage, enhances productivity.
