Before opening the front mold plate and a rear mold plate, the injection mold front mold pre-demolding mechanism leads the front mold insert to release from the product plastic position, thereby reducing viscous force of the front mold to products and avoids that products are adhered on the front mold when opening the front mold plate and the rear mold plate.
Description
Technical field
The utility model belongs to the injection mold field, relates in particular to a kind of injection mold front mould elder generation's mould emptier and comprises the injection mold of this front mould elder generation mould emptier.
Background technology
In the existing injection mold field, because of the product function requirement, product is positioned at the part-structure complexity of front mould, big as fluted or protruding bone bond area, because product can shrink, and the viscous force that product is positioned at the front mould part is bigger than back mould, product can glue front mould during die sinking behind the injection mold internal shaping.
At the problems referred to above, general solution is:
(1) place, front mould glue position is strengthened economizing light, improve the fineness of surface of the work;
(2) change product structure, the draw taper of increasing front mould product;
(3) change product structure at back mould design back-off, strengthens back mould viscous force;
(4) at front mould design thimble structure, by this thimble structure product is ejected from front mould during die sinking.
But said method has following defective:
(a) method (1) is economized light repeatedly to front mould, and labour intensity is big, has prolonged the molding time;
(b) method (2) has been changed the structure of product though strengthened the draw taper of product front mould glue position, can't satisfy the specific (special) requirements of client to product;
(c) method (3) has equally also been changed the structure of product, can't satisfy the specific (special) requirements of client to product;
(d) method (4) makes mould structure complicated at front mould design thimble structure, has increased the manufacturing cost of mould.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Consult Fig. 1～shown in Figure 7; the first mould emptier of a kind of injection mold front mould that the utility model embodiment provides; comprise a front template 2; one is embedded at the preceding die 3 on the described front template 2; one is embedded at the front mould mold insert 12 on the described preceding die 3; one fixed block 10 of fixedlying connected and two support columns 6 that are fixedly arranged on described fixed block 10 opposite sides with described front mould mold insert 12; also be equipped with two on the described fixed block 10 and be positioned at the stop screw 9 of the same side with described front mould mold insert 12; described stop screw 9 is fixed on the preceding die 3; and be arranged with a spring 11 on the described stop screw 9, described support column 6 wears and protrudes from described front template 2.
Further, fixedly connected with two pins 8 by two screws 7 between described front mould mold insert 12 and the fixed block 10; One end of described support column 6 is threaded between the described end of thread 61 and the fixed block 10 for the threaded end of thread 61 of processing; Described spring 11 1 ends support the head that terminates in described stop screw 9, and the other end of described spring 11 supports in the groove that terminates in described preceding die 3.
Consult Fig. 2～shown in Figure 7, the utility model embodiment also provides a kind of injection mold that comprises the first mould emptier of foregoing front mould, it comprises a runner plate 1, a thimble panel 13, the Ejector Retainer Plate 14 that cooperates with described thimble panel 13 and some thimbles 15 that is fixedly arranged on the described thimble panel 13, and described runner plate 1 is connected with front template 2; When the injection mold matched moulds, described runner plate 1 compresses the support column 6 that protrudes from described front template 2 downwards, and support column 6 drives fixed block 10 and moves downward, thereby makes fixed block 10 with spring 11 compressions, makes spring 11 be in compressed state behind matched moulds.
Injection mold front mould that the utility model embodiment is provided elder generation's mould emptier and comprise that the concrete course of work of injection mold of this front mould elder generation mould emptier is as follows:
(1) shown in Fig. 2 and 3, behind injection mold front template 2 and rear pattern plate 5 matched moulds, injection machine die 3 is forward injected the sizing material of thawing with the cavity that back die 4 forms;
(2) as Fig. 4 and shown in Figure 6, injection mold insulation, pressurize and after cooling, injection mold is from separating earlier (PL1 die joint as shown in Figure 4) between front template 2 and the rear pattern plate 5, then separate (PL2 die joint as shown in Figure 4) between runner plate 1 and the front template, this moment, compressed spring 11 was released, spring 11 promotes fixed block 10 and front mould mold insert 12 breaks away from preceding die 3, before front template 2 and rear pattern plate 5 die sinkings, make front mould mold insert 12 break away from product glue position earlier, so just reduced the viscous force of front mould product;
