Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a high-efficiency plastic product molding mold. Background Technology
[0002] Plastic product molding molds are key equipment in plastic processing and production. They mainly consist of mold cores, templates, and guiding mechanisms. During production, molten plastic is injected into the mold cavity, and after cooling and solidification, the molded plastic product is removed through the demolding mechanism.
[0003] In the current application of plastic product molding molds, the mold core is usually fixed to a designated position on the template with fasteners. When there is a need to replace the mold core, the staff must first loosen the fasteners of the mold core. Only after the fasteners are completely loosened can the mold core be disassembled. This process is cumbersome and affects the efficiency of mold replacement to some extent. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0032] Please refer to Figures 1 to 5 Example 1:
[0033] This utility model proposes a high-efficiency plastic product molding die, comprising: a female molding substrate 1, with molding guide pillars 2 fixedly installed at the four corners of the top of the female molding substrate 1; a male molding substrate 3 slidably installed on the molding guide pillars 2; a female groove 7 is formed at the center of the top of the female molding substrate 1; a female molding die 14 is slidably installed inside the female groove 7; a limiting block A8 is fixedly installed at the rear end of the female groove 7; push plates A9 are fixedly installed on the left and right sides of the rear end of the female groove 7; sliding plates A10 are slidably installed on the left and right sides of the front end of the female groove 7; a male groove 15 is formed at the center of the bottom of the male molding substrate 3; a male molding die 21 is slidably installed inside the male groove 15; a limiting block B16 is fixedly installed at the front end of the male groove 15; push plates B16 are fixedly installed on the left and right sides of the front end of the male groove 15. 17; Sliding plates B18 are slidably installed on the left and right sides of the rear end of the male groove 15. When the male mold 21 and female mold 14 are not in use, they can automatically make the male mold 21 and female mold 14 slide in connection with the male molding substrate 3 and female molding substrate 1 respectively, so that the male mold 21 and female mold 14 can be quickly disassembled when not in use, improving the disassembly efficiency of this molding die. When the male mold 21 and female mold 14 are docked and ready for use, the male mold 21 and female mold 14 will be blocked and limited by the corresponding sliding plate structure to ensure the stability of the male mold 21 and female mold 14 under normal use. This ensures the efficient disassembly of the male mold 21 and female mold 14 and prevents the male mold 21 and female mold 14 from being unsecured.
[0034] In Example 2, based on Example 1, a restoring spring A4 is embedded between the bottom of the male molding substrate 3 and the top of the female molding substrate 1; a fixing plate 5 is fixedly installed on the top of the molding guide post 2; push cylinders 6 are fixedly installed on the left and right sides of the top of the fixing plate 5; the output end of the push cylinder 6 is connected to the top of the male molding substrate 3; the top of the sliding plate A10 has an inclined structure; an insert A11 is fixedly installed at the bottom of the sliding plate A10; a restoring spring B12 is embedded between the two inserts A11. The push cylinder 6 is activated, causing it to move the male molding base plate 3 and the male molding mold 21 downwards. During the movement, the push plate A9 and the push plate B17 will push the inclined surfaces of the sliding plate B18 and the sliding plate A10 respectively, causing the sliding plate B18 and the sliding plate A10 to start moving inwards under the influence of the push. The sliding plate B18 and the sliding plate A10 will then block and limit the male molding mold 21 and the female molding mold 14 respectively by moving inwards, thereby ensuring the stability of the male molding mold 21 and the female molding mold 14 under normal use.
[0035] In Example 3, based on Example 2, an injection hole 13 is provided at the center of the top of the male molding substrate 3; the bottom end of the sliding plate B18 is inclined; an insert B19 is fixedly installed at the top of the sliding plate B18; a restoring spring C20 is embedded between the two inserts B19; the positions of the sliding plate B18 and the push plate A9 are vertically aligned; the positions of the sliding plate A10 and the push plate B17 are vertically aligned. After the male molding substrate 3 rises and restores the male mold 21, the push plates A9 and B17 will release the inclined push on the sliding plates B18 and A10, so that the sliding plates B18 and A10 will be restored under the action of the corresponding restoring springs, so that the sliding plates A10 and B18 will release the obstruction and limitation on the female mold 14 and the male mold 21, making it convenient for the workers to disassemble and replace the female mold 14 and the male mold 21.
[0036] Working principle: During use, the push cylinder 6 is activated, causing it to move the male molding base plate 3 and the male molding mold 21 downwards. During the movement, the push plates A9 and B17 push against the inclined surfaces of the sliding plates B18 and A10 respectively, causing the sliding plates B18 and A10 to move inwards under the influence of the push. This inward movement of the sliding plates B18 and A10 provides resistance and limitation to the male molding mold 21 and the female molding mold 14, thereby ensuring the proper functioning of the male molding mold 21 and the female molding mold 14. The stability of mold 14 under normal use, and after the male molding substrate 3 rises and restores the molding male mold 21, the push plate A9 and push plate B17 will cancel the inclined push of the sliding plate B18 and sliding plate A10, so that the sliding plate B18 and sliding plate A10 will be restored under the action of the corresponding restoration spring, so that the sliding plate A10 and sliding plate B18 will cancel the blocking and limiting of the molding female mold 14 and molding male mold 21, making it convenient for the staff to disassemble and replace the molding female mold 14 and molding male mold 21.
