Die-casting die capable of preventing sliding block from moving backwards

Abstract

The invention discloses a die-casing die capable of preventing a sliding block from moving backwards. The die-casting die capable of preventing the sliding block from moving backwards comprises a movable fixing device, a lifting clamping device and a casting die device, the lifting clamping device is arranged on the movable fixing device, and the casting die device is arranged on the lifting clamping device. The invention belongs to the technical field of dies, and particularly relates to the die-casting die capable of preventing the sliding block from moving backwards. Through the lifting function of the die-casting die, lifting of the die-casting die is controlled, a clamping sliding block at the upper end is clamped in a die clamping groove at the lower end, hydraulic limiting treatmentis conducted on the clamped sliding block in order to prevent the temperature of a pouring solution from being too high to affect the accuracy of the die, the phenomenon that a clamping port is deformed and affects product quality is avoided, and the problems that an existing die-casting die in the current market is low in efficiency, complex in structure and inconvenient to maintain are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a die-casting mold for preventing a slide block from moving backward. Background technique [0002] Die-casting is widely used for engine covers and cylinder heads, but the size of such products is relatively large, and the volume of the mold produced is relatively large. During die-casting, die-casting pressure of more than 500T is usually required. In the actual production process, due to pressure If the slider is too large, if the slider of the mold is controlled by an oil cylinder, it is easy to cause the slider to move backward, which will affect the molding of the product. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a die-casting mold that prevents the slider from moving backward. Through the lifting function of the die-casting mold, the lifting of the die-casting mold ...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a die-casting mold that prevents the slider from moving backward. Through the lifting function of the die-casting mold, the lifting of the die-casting mold is controlled, and the engaging slider at the upper end is engaged with the mold at the lower end. In order to avoid the high temperature of the pouring solution from affecting the accuracy of the mold, the hydraulic limit treatment is performed on the engaged slider to avoid the deformation of the engaging port and affect the quality of the product, which effectively solves the existing die-casting problems in the market. Low mold efficiency, complex structure and inconvenient maintenance
