Description
Technical Field
[0001] This utility model belongs to the field of home appliance mold technology, and in particular relates to an automatic demolding device for home appliance molds. Background Technology
[0002] Home appliance molds are specialized tools used to manufacture various parts or housings for home appliances. They are mostly used in injection molding, stamping, or die casting equipment to process materials (such as plastics and metals) into specific shapes.
[0003] For example, Chinese patent CN221754462U discloses an automated stamping device for household appliance hardware accessories, including a base, a support frame welded to the upper surface of the base, a stamping cylinder on the top of the support frame, a stamping head fixedly installed at the telescopic end of the stamping cylinder, a mold seat fixedly installed on the upper surface of the base, a stamping die inside the mold seat, a limit component on the side of the stamping die, and a cooling mechanism inside the mold seat. This utility model can fix the stamping die in the mold seat through the limit component, preventing the stamping die from shifting during the stamping process and causing incorrect processing of hardware accessories. Moreover, by pressing the pressing rod, the movable plate and the clamping plate can be moved left and right. When the clamping plate disengages from the slot of the connecting plate, the mounting bracket can be removed, thereby removing the stamping die from the mold seat. Compared with the bolt fixing method, this application makes it more convenient to replace the stamping die, indirectly improving the stamping efficiency.
[0004] The aforementioned patent has the following problems:
[0005] This patent has some drawbacks in its use. For example, the aforementioned stamping device requires the user to disassemble the mounting bracket and then remove the stamping die from the die holder. However, because the stamping die is formed by stamping, it tends to get stuck tightly in the die holder, making it difficult for the user to remove it and affecting work efficiency. Therefore, we propose an automatic demolding device for household appliance molds. Utility Model Content
