Preferably, which further includes the first accessory part 141 and the second accessory part 142, the first assisted group
Part 141 and the second accessory part 142 are relatively installed on the two sides of the first injection molding cavity.Specifically, the first accessory part 141 includes
First auxiliary mounting blocks 1411 and the first type position bar 1412, the second accessory part 142 include the second auxiliary mounting blocks 1421 and the
Two type position bars 1422, the first auxiliary mounting blocks 1411 are fixedly installed between mold upper casing 110 and mold lower casing 120, and first is auxiliary
Mounting blocks 1411 are helped to be equipped with the first mounting hole, the first type position bar 1412 is inserted in the first mounting hole, and the first type position bar
1412 end extends to the first injection molding cavity, and the second auxiliary mounting blocks 1421 are fixedly installed in mold upper casing 110 and mold lower casing
Between 120, the second auxiliary mounting blocks 1421 are equipped with the second mounting hole, and second type position bar 1422 is inserted in the second mounting hole,
And the end of second type position bar 1422 extends to the first injection molding cavity, second type position bar 1422 is set relatively with the first type position bar 1412
It sets.In injection molding process, the end of the first type position bar 1412 and the end of second type position bar 1422 are as the first injection molding cavity
Cavity wall component part, during being molded ebonite material injection part, the end present position of the first type position bar 1412 is formed
For an end of ebonite material injection part, the end present position of second type position bar 1422 is shaped to ebonite material injection part
Another end.Due to the end of the first type position bar 1412 and the molding ebonite material in end position place of second type position bar 1422
The end for expecting moulding is the moulding end with groove structure, in this way, needing after die sinking by the first type position bar 1412
It is extracted out from the first mounting hole of the first auxiliary mounting blocks 1411, second type position bar 1422 is assisted into mounting blocks 1421 from second
It extracts out in second mounting hole, then Injection Molding Products 300 could be removed from mold cores 100.
Ebonite material injection part, flexible glue material moulding are completed in injection molding, and waits ebonite material injection part and flexible glue
Connecting shaping is completed to need to be opened mold cores 100, by mould after Injection Molding Products 300 between material injection part
Tool upper casing 110 carries out separating die sinking with mold lower casing 120, and Injection Molding Products 300 are retained under the action of mold stresses at this time
(mold stresses are to form the first injection molding cavity and the second injection molding cavity Process Design of mold cores 100 in design on mold lower casing 120
The stress distribution difference of formation, i.e. design are so that the stress between mold lower casing 120 and Injection Molding Products 300 is greater than mold
Stress between upper casing 110 and Injection Molding Products 300, thus Injection Molding Products 300 can be retained in mold lower casing after die sinking
On 120), at this point, Injection Molding Products 300 are ejected from mold lower casing 120 by demoulding thimble (not shown) again.In this implementation
In example, type core supporting element is equipped with thimble via hole 231, and conversion hysteria core 130 is equipped with thimble escape groove 131, and demoulding thimble is successively
