The positioning structure of the mold

Abstract

The invention discloses a positioning structure of a mold, which is arranged in a mold for embedding plastic parts in metal parts. The mold includes a female mold core, a male mold core and a positioning column. The positioning structure of the mold includes: a push rod, It is set on the bottom surface of the female mold core; a shift block is set in the male mold core and is located below the ejector rod; two positioning blocks are set in the male mold core, and the two positioning blocks are respectively Located on both sides of the shifting block, the shifting block slides up and down between the two positioning blocks, one of the positioning blocks is at a certain distance from the metal part; elastic elements are respectively arranged on the male mold core and the metal part Between the shifting block and the positioning block, the elastic element pushes the shifting block and the positioning block to move through elastic deformation. The positioning structure of the mold of the present invention, through the cooperation between the ejector rod, the shifting block, the positioning block and the elastic element, can prevent the metal parts from forming failure caused by sliding during forming.

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...

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
