Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold technology, and in particular relates to a limiting structure to prevent the slide from retracting. Background Technology
[0002] Different molds are made up of different parts. They mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are known as the "mother of industry".
[0003] Existing molds produce products with undercut holes, requiring slides. However, because the products are large, the mold also needs to be large, requiring two-plate molds. Furthermore, the slides must be centered in the mold, making it impossible to use a shovel base for limiting movement. This is because the slides need to retract before mold opening, so conventional slide construction is not feasible. Therefore, we provide a limiting structure to prevent slide retraction, thus solving the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a limiting structure to prevent the slide from retracting. By combining the slide core-pulling limiting structure and the secondary slide core-pulling, the problem of undercut holes in the mold products in the prior art is solved.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0012] The present invention is further configured such that secondary sliding cores are slidably connected to both sides of the primary sliding core pulling, and the two secondary sliding cores on each side are located between the two first slider pressure plates.
[0013] By adopting the above technical solution, a connecting seat is installed on the top of the multi-slot connecting block, and the top of the connecting seat is used to install the sliding core pulling limit structure, the first slider pressure plate, the hydraulic cylinder drive, the primary sliding core pulling, the limit block, the second slider pressure plate, and the secondary sliding core pulling.
[0014] The present invention is further configured such that the primary row core pulling is an isosceles triangle, and the two secondary row core pullings are obliquely arranged on both sides of the primary row core pulling.

[0017] By adopting the above technical solution, the sliding core pulling limiting structure moves once under the action of the hydraulic cylinder, and then the hydraulic cylinder continues to open the mold and pull the sliding core pulling limiting structure to move.
[0018] The present invention is further configured such that a multi-slot connecting block is fixedly connected to the top of the base, and the multi-slot connecting block is inserted into the bottom opening of the outer shell.
