Description

Technical Field

[0001] This utility model belongs to the field of molding die technology, specifically relating to a molding die for TC bearing bodies. Background Technology

[0002] TC bearing housing molding molds are specialized molds used to produce TC bearing housings. TC bearings, also known as cemented carbide bearings, are key components manufactured using a high-temperature furnace sintering process. The housing is fused with tungsten carbide powder and cemented carbide, and then machined. The working principle of the TC bearing housing molding mold mainly involves two processes: injection molding and cooling solidification. Specifically, molten material is injected under high pressure into the mold cavity using an injection molding machine. The mold typically consists of a bottom mold and a top mold. After injection molding, the finished product within the mold is rapidly cooled and solidified by a cooling system, resulting in the TC bearing housing of the desired shape and size.

[0003] Chinese Patent Publication No. CN216423286U discloses a TC bearing carcass molding mold, including a bottom mold and a coolant box. The bottom mold has telescopic rods at both ends of its rear side, with a top mold hinged to the top of each rod. The front side of the bottom mold has a placement groove. The rear side of the coolant box has a cooling pipe located inside the placement groove. A water pump is located inside the coolant box, and a cooling plate is located on the rear side inside the coolant box. The cooling pipe on the rear side of the coolant box is inserted into the placement groove, and the top mold is placed on top of the bottom mold using the telescopic rods. A fastening assembly is located on the side of the top mold, and a fixing assembly is located on the front side of the bottom mold. The mold also includes a transparent window located on the front side of the coolant box. The input ends of the cooling plate and the water pump are electrically connected to the output end of an external controller. This TC bearing carcass molding mold is robust, practical, and efficient.

[0004] In actual use, this utility model typically involves two major steps: injection molding and cooling and solidification. However, the existing TC bearing body molding molds usually rely on a single cold water component to cool the molten TC bearing body material. This cooling method has low efficiency, which limits the solidification speed of the TC bearing body, thus slowing down the overall production process and resulting in low production efficiency. Consequently, the efficiency of the TC bearing body molding mold is somewhat lacking. Utility Model Content
