Description

Technical Field

[0001] The utility model relates to the technical field of mold splitting equipment, in particular to a mold splitting device. Background Art

[0002] In the production process of automotive parts, it is usually necessary to demold the molded parts for subsequent processing.

[0003] A Chinese patent with application publication number CN211758145U discloses a demoulding device for automotive parts molds. In the patent, when a part is stuck and cannot be removed after being stamped, an employee manually pushes the push contact to the right, so that the transmission connecting rod drives the demoulding shovel plate to the right and inserts it into the gap between the part and the mold to loosen the part and the mold. At the same time, the movable insertion rod is pushed to the left, and the lower clamp is inserted into the bottom edge of the molded part. At the same time, the upper pressure plate squeezes the part downward under the action of the extrusion spring, so that the lower clamp and the upper pressure plate cooperate to clamp the part, and the movable insertion rod is lifted upward to realize the demoulding of the part.

[0004] When using the above patent, we found that the device requires manual labor to take out the parts, which is time-consuming and labor-intensive, resulting in an increase in the workload of workers, thereby greatly reducing work efficiency. Therefore, we proposed a mold separation device. Utility Model Content
