Description

Be applied to special mold insert of hand pump cover pilot hole of filter base injection mold Technical Field The utility model relates to the technical field of injection mold cooling structures, in particular to a special insert for a hand pump cover assembly hole of a filter base injection mold. Background In an injection mold cooling system, the appearance quality and the dimensional stability of an injection molding piece are directly influenced aiming at the temperature control effect of a local structure of a product. The existing mold is often provided with an annular channel or a drilling channel inside the insert to serve as a cooling water channel, and the existing mold is simple in structure and convenient to process, but is difficult to realize efficient and uniform cooling control at a position with limited space or complex shape. Particularly in hole inserts with assembly function, such as hand pump cover assembly hole inserts of filter base injection molding products, the traditional cooling mode is difficult to balance the temperature of the whole area due to the closed structure, uneven wall thickness and serious heat accumulation. In the current practical application, part of the die designs still adopt unidirectional flow or symmetrical water-through designs, the water path arrangement is lack of pertinence, the water flow path is short, the heat exchange area is small, the residence time of the cooling liquid in part of the area is too short, and the local heat dissipation is insufficient. In order to enhance the cooling effect, some designs introduce annular water tanks, but do not partition the flow channels, so that the cooling liquid easily flows along the shortest path, and the temperature field is unevenly distributed. The structure is particularly prominent in the position of the assembling hole of the hand pump cover, and often has the quality problems of bulge, welding lines or uneven gloss after molding, thereby seriously affecting the appearance and the assembling precision of the product.
