Problems solved by technology

Among them, the upper mold and the lower mold can be used in the production of power adapter shells with different shapes, and the insert must match the power adapter shell. If the local characteristics of the power adapter shell need to be adjusted, it is also necessary to re-open the mold to make the insert ,higher cost
At the same time, due to the size and structural limitations of inserts, the replacement process is complicated, time-consuming and laborious

Abstract

The invention discloses a split type insert for an injection mold. The split type insert comprises an insert main body, an insert split body, a positioning needle and a jacking assembly, a clamping groove is formed in the surface of the insert main body, and a first positioning hole is formed in the bottom surface of the clamping groove; the insert split body is detachably arranged in the clamping groove, and a second positioning hole corresponding to the first positioning hole is formed in the insert split body; one end of the positioning needle upwards penetrates through the first positioning hole and extends into the second positioning hole; and the jacking assembly is arranged at the other end of the positioning pin and is used for enabling one end of the positioning pin to extend into or retreat from the second positioning hole. According to the split type insert for the injection mold, the insert is convenient to replace, and the overall manufacturing cost of the insert is reduced.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a split insert for an injection mold. Background technique [0002] The housing of the power adapter is generally formed by injection molding. Injection molding requires a corresponding injection mold. A common power adapter injection mold includes an upper mold, a lower mold, and an insert between the upper mold and the lower mold. Among them, the upper mold and the lower mold can be used in the production of power adapter shells with different shapes, and the insert must match the power adapter shell. If the local characteristics of the power adapter shell need to be adjusted, it is also necessary to re-open the mold to make the insert ,higher cost. At the same time, due to the size and structural limitations of the inserts, the replacement process is complicated, time-consuming and laborious. Contents of the invention [0003] The object of the present invention is...
