Inverter box forming mold

Abstract

The invention discloses an inverter box forming mold. The inverter box forming mold comprises a fixed mold and a movable mold, wherein the fixed mold and the movable mold are clamped, and match each other, a mold cavity is formed by contact surfaces of the fixed mold and the movable mold, a locking mechanism and lateral molds are arranged between the fixed mold and the movable mold, the lateral molds match the locking mechanism, and move at two sides of the mold cavity, the locking mechanism comprises tilted guiding columns, a sliding block and a guiding rail, the guiding rail is arranged on the movable mold, the tilted guiding columns are arranged on the fixed mold while tilting to the outer side, the sliding block is slidingly connected with the tilted guiding columns and the guiding rail at the same time, multiple overflow grooves are formed in the portions, on the periphery of the mold cavity, on the fixed mold and the movable mold, expanding devices are arranged in the lateral molds, the expanding devices can control the lateral molds to be detached from the corresponding overflow grooves in the movable mold, a cutting device is arranged on the fixed mold, when the lateral molds slide, the cutting device can match the lateral molds to cut the corresponding overflow grooves in the fixed mold, automatic demolding operation can be quickly conducted, and part of waste is cut off in advance during demolding, so that subsequent processing is facilitated.

Description

technical field [0001] The application relates to the field of mold technology, in particular to an inverter box forming mold. Background technique [0002] Die-casting mold is a tool for casting metal parts, a tool that completes 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 at a low or high speed and filled into the cavity of the mold. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which eliminates the shrinkage of the blank. Loose defects also make 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; in order to improve the quality of die castings, in the process of filling the cavity with molten metal, it should be eliminated as much as possible. Inclusions, paint residues, and the removal of the pr...

Problems solved by technology

[0003] However, the existing forming molds have the following defects: in the process of die-casting, it is necessary to wait for the molten metal inside the mold to be cooled before demoulding, and the waiting time for forming is long. In addition, most of the products formed by die-casting are irregular in shape. When designing, it is necessary to use multiple molds for assembly. When demoulding after die-casting, it is more troublesome to disassemble molds with different shapes and different fits. However, due to the presence of overflow tank waste around the product, demoulding is more difficult, and finally smooth After demoulding, the waste needs to be processed, which is less efficient
