Abstract

The invention discloses a die-casting die structure. The die-casting die structure comprises a front mold plate, a first back mold plate, a second back mold plate, a first ejector plate, a second ejector plate and a bottom plate which are successively arranged. A first mold core is arranged between the front mold plate and the first back mold plate, and a second mold core is arranged between the first back mold plate and the second back mold plate; an ejector pin is arranged on the ejector plate, an oil cylinder is fixed to the second back mold plate, and the oil cylinder can drive the first ejector plate to move front and back to eject a product formed in the first mold core; the second ejector plate is fixedly connected to the first back mold plate, and an ejector rod of a die-casting machine penetrates through the bottom plate and is fixed to the second ejector plate and can drive the second ejector plate to move front and back to eject paint slag in the second mold core. Accordingto the die-casting die structure, a conventional two mold plate structure is changed to a three mold plate structure. One of the mold plates is used for forming the product while the other mold plateis used for discharging slag and ejecting the product, so that the problem that the product is not filled well when product column positions which are higher and more are available is solved, and thequality of the pressure casting products is improved.

Description

technical field [0001] The invention relates to a mold structure, in particular to a die-casting mold structure. Background technique [0002] At present, the existing die-casting molds generally include a front mold and a rear mold. The front mold core is set in the front mold, the rear mold core is set in the rear mold, and the mold is opened and closed to form products. However, due to the structure of the existing die-casting mold, the material The position, slag discharge and ejection structure are all in the rear mold core, so when the die-casting mold is used to produce products with higher column positions, due to the limitation of the product structure, the column positions will be filled when the module is opened for die-casting products Poor, resulting in the accuracy of die-casting products affected. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a die-casting mold structure, which can effect...
