Description

Technical Field

[0001] This utility model relates to a mold grinding device for refrigerator production, belonging to the technical field of polishing and grinding equipment. Background Technology

[0002] Refrigerators are assembled from multiple parts. Some metal parts are made by stamping, while most plastic parts are made by injection molding. Both stamping dies and injection molds require regular maintenance, and polishing is one of the maintenance methods.

[0003] A search revealed Chinese patent 2020233014275, which discloses a grinding device that uses a mold-mounted clamping method. It is known that the mold is heavy, and the upper clamping method has problems such as difficulty in clamping and easy falling. In severe cases, it may damage the grinding head below.

[0004] In addition, it is inconvenient to adjust the position of the grinding during the grinding process. Grinding can only be carried out in the horizontal direction unless the grinding head is made very large enough to cover the entire grinding surface, which would increase the size of the equipment.

[0005] Some companies use robots for polishing, but the price and maintenance costs of robots are high, which is generally unaffordable for most companies.

[0006] To address the shortcomings of traditional technologies, our company offers an alternative approach to mold polishing. Utility Model Content
