Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a silicone injection mold which is easy to clean. Background Art

[0002] Silicone molds are special molds for making handicrafts. The raw materials of rubber can be divided into ordinary silicone and meteorological silicone according to their performance. Silicone is characterized by high temperature resistance, corrosion resistance, strong tear resistance, and high simulation fineness. It is a mold for making various handicrafts.

[0003] To prevent the silicone from flowing around, the mold is fixed in a regular range with wooden blocks or boards. When opening the mold, the wooden board and the oil mud are used to separate the first part. It is required that there is no gap between the oil mud and the mold, and the surface of the oil mud is smooth and flat. After use, the mold cavity needs to be cleaned, and then drained. Otherwise, the subsequent cleaning operation will be affected by unclean cleaning or water not drained. However, the existing integrated design of silicone molds makes the overall operation inconvenient, affecting the efficiency of use and cleaning. For this reason, we propose a silicone injection mold that is easy to clean. Utility Model Content
