Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a demoulding device for an automobile die casting mould. Background Art

[0002] Die casting mold is a tool for casting metal parts, a tool for completing the die casting process on a special die casting die forging machine. The basic process of die casting is: the molten metal is first cast and filled into the mold cavity at a low speed or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools down, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state, and the comprehensive mechanical properties of the blank are significantly improved. The demoulding device of the automotive die casting mold assists the demoulding of the die casting mold.

[0003] In view of this, Chinese Patent No. CN220311718U proposes an automotive die-casting mold demolding device, which first drives the knob to drive the transmission rod to rotate, and under the meshing connection of bevel gear one and bevel gear two, the screw is rotated and drives the moving block to move upward. The upward movement of the moving block synchronously drives the main push plate and the annular push plate to push the steering wheel in the molding cavity upward, and then supports the steering wheel from the bottom and the side while providing a lifting force, so that the steering wheel is easy to demold. In the above patent, when the automotive die-casting mold demolding device demolds the steering wheel part, due to the large internal mold engagement friction of the steering wheel, it is easy to cause the hidden danger of deformation caused by excessive demolding force during demolding, which increases the difficulty of demolding the steering wheel part in the automotive spare parts. Therefore, a automotive die-casting mold demolding device is needed. Utility Model Content
