The working principle of the technical scheme of the invention is as follows: when the mold is used for core pulling, as shown in fig. 1 and 10, the insert pin on the first slide mechanism 100 moves backward to perform core pulling on the deep hole 810 on the molded product 800. Then, as shown in fig. 9 and 10, the shovel 600 moves upward, the wear-resistant block 620 on the shovel 600 drives the third position mechanism 400 to move backward, and when the third position mechanism 400 moves backward, the shifting block 420 slides downward in the third position mechanism 400 and moves backward together with the third position mechanism 400, so as to drive the slide insert 421 to slide downward and move backward in the first inclined hole 340, thereby completing the core pulling of the second inclined hole 820 on the molded product 800. After the third slide mechanism 400 moves backwards to the second end of the bayonet 700 to be clamped in the second V-shaped groove 410, because the side walls on the two sides of the second V-shaped groove 410 have a certain height difference, the third slide mechanism 400 is supported by the bayonet 700 and cannot move backwards continuously, at this time, the first end of the bayonet 700 is forced to start sliding backwards in the sliding groove 210 of the slide bar 200, and drives the second slide mechanism 300 and the third slide mechanism 400 to move backwards until the elastic positioning pin 230 on the slide bar 200 is clamped in the positioning groove on the second slide mechanism 300, so that the second slide mechanism 300 can loose core for the plurality of narrow grooves 830 on the molded product 800. While the second slide mechanism 300 moves backwards, the fourth slide mechanism 500 starts to slide on the second slide mechanism 300 and moves backwards under the action of the second slide mechanism 300, so that the fourth slide mechanism 500 pulls cores for a plurality of triangular holes 840 on the molded product 800, and the core pulling action of the whole core pulling structure from a plurality of directions on the molded product 800 is completed.
Compared with the prior art, the invention has the beneficial effects that:
1. the whole structure is simple and compact, the multiple slide mechanisms are used for pulling cores along respective directions, and the problem that local features of products are difficult to demould due to narrow and complex space is solved.
2. The multi-direction core pulling is performed by arranging the plurality of slide mechanisms on the injection mold, so that the strength of the core pulling structure of the mold and the structural strength of a formed product 800 are ensured, the service life of the mold is prolonged, and the forming quality of the product is improved.
