Problems solved by technology
[0002] Existing products with undercuts in the direction of the slider’s core pulling cannot be forcibly removed. After the processing is completed, secondary processing is carried out at the undercut position to complete the manufacture of the product, which is time-consuming and laborious, and the processing efficiency is low.

The invention provides a coring structure with an inverted buckle in the coring direction of a slide block, which can be used for forming a product with the inverted buckle in the coring direction of the slide block in one step and has the advantages of time and labor saving and high processing efficiency. The coring structure comprises the slide block and a locking block which is connected with the slide block, and is characterized in that the inverted buckle part of the product to be processed is provided with an oblique top insert,, the outer side of which is matched with the inverted buckle part; the inner side of the oblique top insert is communicated with a contractive bevel in the center of the product; a convex block which extends outwards is installed at the inner side of the oblique top insert; the outer side of the slide block is a bevel; a guide rail is embedded into the outer side of the slide block; and the convex block is embedded into the guide rail.
Description
technical field [0001] The invention relates to the technical field of core-pulling structures of injection molds, in particular to a core-pulling structure with an undercut in the core-pulling direction of a slider. Background technique [0002] Existing products with undercuts in the direction of the slider’s core pulling cannot be forcibly removed. After the processing is completed, secondary processing is carried out at the undercut position to complete the manufacture of the product, which is time-consuming and laborious, and the processing efficiency is low. . Contents of the invention [0003] In view of the above problems, the present invention provides a core-pulling structure with an undercut in the core-pulling direction of the slider, which can form a product with an undercut in the core-pulling direction of the slider at one time, saving time and effort, and has high processing efficiency. [0004] The core-pulling structure with an undercut in the core-p...
