Description

Technical Field

[0001] This utility model relates to the field of molding compound cage technology, specifically to a molding compound cage cooling and shaping device. Background Technology

[0002] Molding molded plastic cages are key components widely used in bearings. Their main function is to separate rolling elements (such as balls or rollers) to prevent them from colliding during operation, thereby reducing friction and wear and extending bearing life. Molding molded plastic cages are typically manufactured using injection molding processes and have advantages such as being lightweight, wear-resistant, and corrosion-resistant. They also possess good self-lubrication and a low coefficient of friction, making them perform excellently at high speeds.

[0003] A plastic retainer injection mold with a cooling mechanism, as disclosed in announcement number CN222346226U, includes a mounting base with multiple support feet fixedly connected to its bottom. An upper mold is positioned above the mounting base and connected to it via an adjustment mechanism. A cooling groove is formed on the upper surface of the mounting base. This invention uses a built-in water pump in a cooler to guide cooling water into a water pipe. The cooling water flows along the water pipe, inlet pipe, and inlet hole into the cooling groove on the mounting base, where it contacts the outer wall of the lower mold to cool the molded part. A first and second heat-conducting plate on the outer wall of the lower mold increases its surface area. The multiple first and second heat-conducting plates are evenly spaced, ensuring more uniform heat distribution. The cooling water in the cooling groove returns to the cooler through a drain hole and drain pipe, thus forming a cooling water circulation system.

[0004] The above-mentioned device has poor cooling effect during use and is inconvenient for demolding; therefore, we propose a molding compound holder cooling and shaping device to solve the problems mentioned above. Utility Model Content

The placement block is disposed in a placement groove, and four sets of moving blocks are disposed within the placement block. The four sets of moving blocks are symmetrically disposed at the lower ends of four lower modules. Each moving block is provided with a second screw, and the front end of each second screw is provided with secondary bevel gears. Main bevel gears are disposed between the four sets of secondary bevel gears. The lower end of the main bevel gears penetrates through and extends to the lower end of the worktable, and the lower end of the main bevel gears is provided with a second motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides a circulation cavity in the upper mold, and uses the circulation outlet pipe and circulation return pipe on the outside of the circulation cooling device on one side of the cooling device to inject water into the circulation cavity and circulate water, which effectively increases the overall cooling effect. Combined with the cooling groove opened at the upper end of the lower module, the cooling effect is further increased. Coolant is injected into the cooling cavity opened at the lower end of the lower module in advance, so as to achieve the effect of cooling the upper and lower molds at the same time, thereby solving the problem of poor cooling effect.

[0015] (2) By dividing the lower mold into four equal lower modules, and with the moving block set at the lower end of the lower module, the main bevel gear is driven to rotate by the second motor, thereby driving the four sets of secondary bevel gears to rotate. With the rotation of the second screw set at the rear end of the four sets of secondary bevel gears, the lower module is expanded and opened, thus solving the problem of inconvenient demolding.
