Insert fixation device at core-pulling forming position of injection mold

Abstract

The invention discloses an insert fixation device at a core-pulling forming position of an injection mold. The insert fixation device at the core-pulling forming position of the injection mold comprises a slider insert block which is internally provided with an insert pin and a magnet; an insert block is further arranged in the slider insert block; the magnet is embedded in the slider insert block; and one end of the magnet is connected with the insert block. The insert fixation device at the core-pulling forming position of the injection mold has the beneficial effects that an insert is fixedin the manner that the insert pin is magnetized by the magnet, the difficulty that according to an insert fixing manner in the prior art, a resetting action mechanism is complex, operating and running are not reliable, and consequently the insert cannot be installed at the core-pulling forming position is overcome, and the purposes of simplifying the existing production procedure of an insert workpiece, making operating and running easier and more reliable, and improving the product appearance quality are achieved.

Description

technical field [0001] The invention relates to the field of injection mold auxiliary equipment, in particular to an insert fixing device at the core-pulling forming part of an injection mold. Background technique [0002] In the injection molds of the prior art, for those with complex structures, A and B boards are movable, one or more places need to be core-pulled and molded, and iron inserts need to be embedded in the molded places, usually the plastic parts are injected first, and then reused. A technical solution for the electric soldering iron to melt the insert into the plastic product. This technical solution has the following defects: the hot-melt insert will damage the surface of the plastic part and affect the appearance quality of the plastic product, which is not allowed for plastic products with appearance requirements; the accuracy of the hot-melt insert is general, generally only controlled at 10 wires In addition, it is difficult to meet the requirements fo...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problem in the existing technology that the structure is complex, iron inserts need to be embedded in the core-pulling molding, and the A and B plates have no effective support or clamping, only the plastic parts can be injected first and then the inserts are melted. The invention provides an insert fixing device at the core-pulling forming part of the injection mold, which ensures that the insert does not fall off and does not slip during the core-pulling movement of the mold, and realizes the perfect embedding of the insert while the product is core-pulling. Products, so that such products can be molded, injected, cooled, molded, and demolded like products without inserts
