Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a two-stage driving structure that solves the problem of breakage of a relatively long inclined guide column. Background Art

[0002] When designing the mold, for the lateral core pulling action of the product, the inclined guide column is generally used to drive the core pulling. When the slider stroke is long, such as Figure 1 The product shown has an undercut of up to 122mm. If it is driven by an inclined guide column, the inclined guide column is too long and it is easy to break. When the slider core is long, in order to avoid the inclined guide column from breaking when it is too long, a cylinder is generally used to drive it, such as Figure 2 As shown, the undercut is relatively long, the cylinder will take up a large space, which will increase the mold cost and the molding cycle.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a two-stage drive structure to solve the problem of fracture of longer inclined guide columns. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a two-stage driving structure to solve the problem of breakage of a long inclined guide column. The problem of breakage of a single inclined guide column when it is too long is solved by a two-stage driving of the inclined guide column and a shovel base toggle block.
