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 p

Embodiment Construction

[0019] In order to further illustrate the technical means and effects adopted by the present invention, a detailed description will be given below in conjunction with a preferred embodiment of the present invention and its accompanying drawings.

[0020] see figure 2 , figure 2 It is a structural schematic diagram of the positioning structure of the mold of the present invention in the mold clamping state. In this embodiment, the positioning structure 200 of a mold provided by the present invention is set in a mold for embedding plastic parts in metal parts 10, and the mold includes a female mold core 201, a male mold core 202 and a positioning column 20. The positioning structure 200 of the mold includes:

[0021] Ejector pin 210, which is arranged on the bottom surface of the female mold core 201;

[0022] A shifting block 220, which is arranged in the male mold core 202 and is located below the push rod 210;

[0023] Two positioning blocks 230, which are arranged in t...

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. Loose, and even lead to the size of the final molded product does not meet the production req...
