Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, and particularly to a mold slider structure for automatically cutting off a runner. Background Art
[0002] Injection molds are widely used in the production of plastic products, and sliders are widely used in molds. When the runner injects glue on the side of the mating slider, the product and the runner are adhered together, and manual secondary removal of the runner is required, which increases labor costs and working hours. Summary of the Invention
[0003] The problem to be solved by the utility model is to provide a mold slider structure for automatically cutting off a runner, which can realize the automatic separation of the runner and the product and save labor.
[0004] To solve the above technical problem, a mold slider structure for automatically cutting off a runner according to the utility model comprises a first slider and a second slider arranged oppositely, and a plurality of molding runner structures arranged in parallel. The molding runner structure comprises a runner formed between the first slider and the second slider, two products symmetrically arranged on both sides of the runner and formed between the first slider and the second slider, a thimble sleeve arranged between the first slider and the second slider, and a thimble movably arranged in the thimble sleeve. The runner comprises a longitudinal runner and a transverse runner intersecting in a cross shape, and sub-injection sections respectively connected to both ends of the transverse runner. The sub-injection sections are connected to the products, and the bottom end of the longitudinal runner extends into the top end interior of the thimble sleeve and is connected to the top end of the thimble.
[0005] The beneficial effect of the utility model is that: the utility model provides a mold slider structure for automatically cutting off a runner. When the first slider and the second slider are opened, by pushing the thimble to move upward along the thimble sleeve, the runner will be subjected to an upward thrust from the thimble, and the sub-injection section will be separated from the product, thereby realizing the automatic separation of the runner and the two products, eliminating the need for manual removal of the runner, saving labor, improving production efficiency, and reducing production costs.

Detailed implementation manners
[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure.
[0012] All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0014] The present utility model provides a die slide structure for automatically cutting off a runner, which includes a first slide 1 and a second slide 2 arranged oppositely, and a plurality of formed runner structures 3 arranged in parallel. The formed runner structure 3 includes a runner 30 formed between the first slide 1 and the second slide 2, two products 31 symmetrically arranged on both sides of the runner 30 and formed between the first slide 1 and the second slide 2, an ejector sleeve 32 arranged between the first slide 1 and the second slide 2, and an ejector pin 33 movably arranged in the ejector sleeve 32. The runner 30 includes a longitudinal runner 300 and a transverse runner 301 intersecting in a cross shape, and sub-gate sections 302 respectively connected to both ends of the transverse runner 301. The sub-gate section 302 is connected to the product 31, and the bottom end of the longitudinal runner 300 extends to the top inside of the ejector sleeve 32 and is connected to the top end of the ejector pin 33.
[0015] The specific working principle is that when the first slide 1 and the second slide 2 are opened, by pushing the ejector pin 33 to move upward along the ejector sleeve 32, the runner 30 will receive an upward thrust from the ejector pin 33, and the sub-gate section 302 will be separated from the product 31, thereby realizing the automatic separation of the runner 30 from the two products 31, eliminating the need for manual removal of the runner, saving labor, improving production efficiency, and reducing production costs.
[0016] The above implementation manners are only descriptions of the preferred implementation manners of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary engineering and technical personnel in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
