Die casting mold

Abstract

The invention discloses a die-casting die. The die-casting die is used for die-casting a casting with an inclined structure and comprises a male die holder, a female die holder, a male die core, a female die core and one or more inclined die assemblies, wherein the male die core is fixed to the male die holder, the female die core is fixed to the female die holder, a forming cavity is formed between the male die core and the female die core, and the female die core has a vertical die closing position and a vertical die opening position; the inclined die assembly comprises a first drive rod and a first insertion die core forming the inclined structure, and the first insertion die core slides on the male die holder in the inclination direction of the inclined structure and has an inclined die closing position inserted into the forming cavity in a closed mode and an inclined die opening position separated from the forming cavity; the first drive rod is fixed to the female die holder and can be detachably linked to the first insertion die core; when the female die core moves to the vertical die closing position, the first drive rod drives the first insertion die core to move to the inclined die closing position synchronously; when the female die core moves to the vertical die opening position, the first drive rod drives the first insertion die core to move to the inclined die opening position synchronously.

Description

technical field [0001] The invention relates to the field of die casting, in particular to a die casting mold. Background technique [0002] Die casting, full name pressure casting, refers to the casting method of filling the mold cavity with liquid metal under high pressure and high speed conditions, and cooling and forming castings under high pressure to form the required products. It is the most widely used and developed casting process. One of the fastest metal hot forming process methods. As a component forming technology, die-casting adapts to the requirements of product complexity, precision, light weight, energy saving and greening in modern manufacturing industry, and its application fields are constantly expanding. With the continuous improvement of die-casting equipment and process technology, the application range of die-casting products will continue to expand on the existing basis. [0003] Among them, when the die-casting casting has inclined structures such...

Problems solved by technology

However, if the cylinder core pulling method is used, the mold opening time is relatively long, which makes the die casting efficiency low

Moreover, the inclined oil cylinder used for the core pulling of the oil cylinder will increase the overall height of the mold, resulting in a longer installed mold thickness and mold opening stroke, which makes the tonnage requirements of the die-casting machine higher. For example, the original 400-ton die-casting machine can meet the mold opening requirements. Required, if the cylinder core pulling method is used, an 800-ton die-casting machine is required to meet the mold opening requirements

Furthermore, it will also lead to a more complex structure of the mold, increasing the difficulty of making the mold
