Mold positioning structure

Abstract

The invention discloses a mold positioning structure which is arranged in a mold embedding a plastic piece into a metal piece. The mold comprises a female mold core, a male mold core and a positioningcolumn. The positioning structure of the mold comprises an ejector rod, a poking block, two positioning blocks and elastic elements, wherein the ejector rod is arranged on the bottom surface of the female mold core; the poking block is arranged in the male mold core and located on the lower portion of the ejector rod; the two positioning blocks are arranged in the male mold core and are located on the two sides of the poking block correspondingly, the poking blocks slides up and down on the two positioning blocks, and one of the positioning blocks is away from the metal piece by a certain distance; and the elastic elements are arranged among the male die core, the poking block and the positioning blocks and push the poking block and the positioning blocks to move through elastic deformation. According to the mold positioning structure, through cooperation of the ejector rod, the poking block, the positioning blocks and the elastic elements, the situation that forming of the metal piece fails due to sliding can be avoided.

Description

【Technical field】 [0001] The invention relates to a positioning structure, in particular to a positioning structure of a mold. 【Background technique】 [0002] see figure 1 , figure 1 A schematic diagram of a mold structure for embedding plastic parts in metal parts is shown. The mold 100 has a positioning column 110. When molding, the metal piece 120 is first put into the positioning column 110. When the mold is closed, the female mold core presses the metal piece 120 downward, and then injection molding. However, when the mold is clamped, the core of the female mold repeatedly presses down on the positioning pin, which will cause wear on the outside of the positioning pin 110. If things go on like this, the diameter of the positioning pin 110 will become smaller and smaller. The smaller the diameter of the positioning pin 110, the smaller the diameter of the positioning pin 110.

Problems solved by technology

However, when the mold is clamped, the core of the female mold repeatedly presses down on the positioning pin, which will cause wear on the outside of the positioning pin 110. If things go on like this, the diameter of the positioning pin 110 will become smaller and smaller. The smaller the diameter of the positioning pin 110, the smaller the diameter of the positioning pin 110. Loose, and even lead to the size of the final molded product does not meet the production requirements

[0003] In view of this, it is necessary to provide a positioning structure of the mold, which is used to fix the metal parts and prevent the metal parts from moving during injection molding, resulting in the molded products not meeting the production requirements
