Description
Technical field
The utility model relates to a kind of car trunk fender bracket mould bullet piece mould emptier, belongs to the mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic product, like the fender bracket of car trunk etc., according to the product appearance signature analysis, need there be a lateral sliding mould emptier product side; According to traditional method, adopt dynamic model one side to do the slide block demoulding usually, shortcoming is that the lateral sliding distance is big; Sliding stroke reaches 34MM, causes the mould volume big, thereby makes the Angle Pin setting angle big; Cause Angle Pin to fracture easily, during product stripping, product is damaged breaks easily.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, a kind of bullet piece demoulding of on die cavity, adopting to be provided, and is simple in structure, handling ease, and the demoulding is smooth, and production efficiency is high, the car trunk fender bracket mould bullet piece mould emptier that cost is economized.
The technical scheme of the utility model car trunk fender bracket mould bullet piece mould emptier is: comprise upper mould plate and lower bolster, cope match-plate pattern connects die cavity, and the mould pin is installed on the lower bolster, and upper plate and lower roof plate are set between the mould pin; Upper plate connects push rod, on the mould pin core is installed, and constitutes die cavity between core and the die cavity, and the car trunk fender bracket of moulding is arranged in the die cavity; Be shaped on barb on the car trunk fender bracket, it is characterized in that in the side of die cavity the bullet piece being set, the bullet piece contacts with the car trunk fender bracket, and block is installed in the bottom of bullet piece; Be equipped with drag hook on the core, drag hook matches with block, in the bullet piece, is shaped on spacing hole; Die cavity connects Angle Pin down, and Angle Pin passes spacing hole, and Angle Pin is equipped with spring outward; Spring contacts with die cavity, and limited block is installed in the bottom surface of Angle Pin, and limited block contacts with spacing hole.
The car trunk fender bracket mould bullet piece mould emptier of the utility model, during the demoulding, core under the drive of injection machine power with the die cavity die sinking; In die sinking, bullet piece downward and outside both direction under Angle Pin and spring and drag hook effect moves simultaneously, and spring and luggage case fender bracket and barb disengage when outwards moving; After moving to certain stroke, drag hook and block disengage, and the limited block of Angle Pin bottom surface contacts with spacing hole; Make the bullet piece stop to move, but core continues die sinking, accomplish up to the die sinking action; Through push rod product is ejected in the effect of injection machine knock-pin by upper plate and lower roof plate at last, product stripping is accomplished.This programme adopts bullet piece mould emptier to accomplish the demoulding, bullet piece handling ease, and easy for installation, simple in structure, cost of investment is economized.
The car trunk fender bracket mould bullet piece mould emptier of the utility model is equipped with guide plate in described die cavity one side, and guide plate contacts with the bullet piece, and guide plate is displaced sideways its guide effect to spring.Be equipped with the Angle Pin fixed block in the described die cavity, Angle Pin is connected under the Angle Pin fixed block, and the Angle Pin fixed block has been arranged, and it is firm, convenient that Angle Pin connects.
Description of drawings
Fig. 1 is the bullet piece mould emptier structural representation of the utility model;
Fig. 2 is the bullet piece mould emptier generalized section of the utility model.
The specific embodiment
The utility model relates to a kind of car trunk fender bracket mould bullet piece mould emptier, like Fig. 1, shown in Figure 2, comprises upper mould plate 1 and lower bolster 11, and cope match-plate pattern connects die cavity 2; Mould pin 8 is installed on the lower bolster 11, upper plate 9 and lower roof plate 10 are set between the mould pin, upper plate 9 connects push rod 12, and core 7 is installed on the mould pin 8; Constitute die cavity between core 7 and the die cavity 2, the car trunk fender bracket 17 of moulding is arranged in the die cavity, be shaped on barb 18 on the car trunk fender bracket; It is characterized in that in the side of die cavity 2 bullet piece 3 being set, bullet piece 3 contacts with car trunk fender bracket 17, and block 5 is installed in the bottom of bullet piece 3; Be equipped with drag hook 6 on the core 7, drag hook 6 matches with block 5, in bullet piece 3, is shaped on spacing hole 19; Die cavity connects Angle Pin 14 2 times, and Angle Pin passes spacing hole 19, the Angle Pin 14 outer springs 15 that are equipped with; Spring 15 contacts with die cavity 2, and limited block 16 is installed in the bottom surface of Angle Pin 14, and limited block 16 contacts with spacing hole 19.During the demoulding, core 7 under the drive of injection machine power with die cavity 2 die sinkings, in die sinking; Bullet piece 3 downward and outside both direction under Angle Pin 14 and spring 15 and drag hook 6 effects moves simultaneously, and spring 3 disengages with luggage case fender bracket 17 and barb 18 when outwards moving, after moving to certain stroke; Drag hook 6 disengages with block 5, and the limited block 16 of Angle Pin 14 bottom surfaces contacts with spacing hole 19, makes bullet piece 3 stop to move; But core continues die sinking; Accomplish up to die sinking action, through push rod 12 product is ejected in the effect of injection machine knock-pin by upper plate 9 and lower roof plate 10 at last, product stripping is accomplished.This programme adopts bullet piece mould emptier to accomplish the demoulding, bullet piece handling ease, and easy for installation, simple in structure, cost of investment is economized.Be equipped with guide plate 4 guide plates 4 in described die cavity 2 one sides and contact with bullet piece 3, guide plate is displaced sideways its guide effect to spring.Be equipped with Angle Pin fixed block 13 in the described die cavity 2, Angle Pin 14 is connected the Angle Pin fixed block 13 times, and the Angle Pin fixed block has been arranged, and it is firm, convenient that Angle Pin connects.
