Abstract

The invention discloses a secondary die-opening die-casting mold, which includes a panel, an upper mold, a lower mold and an ejector plate, the lower mold is provided with a first buckle plate, and the panel is provided with a second buckle plate and a limiter Pull plate, the upper mold is provided with a telescopic elastic block and a limit groove matched with the limit pull plate, the limit pull plate is slidably arranged in the limit groove, when the mold is closed, the first The buckle plate fastens the telescopic elastic block. When opening the mold, the upper mold first leaves the panel to open the mold, and then the second buckle plate slides against the telescopic elastic block to unlock the upper mold. and the lower mold, and under the limit of the limit pull plate, the lower mold and the upper mold realize secondary mold opening. The secondary mold opening die-casting mold of the present invention can be opened secondaryly, and has simple structure and convenient demoulding.

Description

technical field [0001] The invention relates to a die-casting mold, in particular to a secondary mold-opening die-casting mold with simple structure and convenient separation. Background technique [0002] Existing die-casting molds are generally fed directly on the side of the product, but some products have complex middle structures and large gaps. If the side feed is used, the entire product cannot be formed. It can only use the runner way to feed in the middle, and use the second mold opening method after the die-casting is completed to remove the waste from the runner first and then demould, so as to ensure that the product gets the best feeding position and molding Qualified products. However, the structure of the existing secondary mold opening molds is relatively complicated, and demoulding is inconvenient, which is not conducive to production. Contents of the invention [0003] The object of the present invention is to provide a die-casting mold for secondary mo...
