Description

Technical Field

[0001] The utility model belongs to the technical field of foaming molds, specifically a flip - cover type foaming mold. Background Technique

[0002] A foaming mold is a mold for plastic foaming molding. Specifically, a foaming resin is directly filled into the mold, heated and melted to form a gas - liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the bubble nuclei grow to form a foam plastic part. A flip - cover type foaming mold refers to a foaming mold in which the mold cover can rotate around an axis to open or close.

[0003] At present, the commonly used flip - cover type foaming mold drives the mold base to rotate around the rotating shaft through a telescopic cylinder to realize the connection between the upper mold and the lower mold, so as to realize injection molding filling.

[0004] In actual use, there are still disadvantages. More obviously, after the foaming mold is formed, the finished product is usually in the lower mold, and workers need to use clamping tools such as pliers to take out the finished product from the lower mold, which is not convenient for the discharge of the finished product and reduces the use efficiency of the foaming mold. Therefore, we propose a flip - cover type foaming mold. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flip - cover type foaming mold to solve the problems put forward in the above - mentioned background technique.

One end of a group of rotating shafts penetrates through the top end of the support column and is fixedly connected to the first synchronous pulley. The second synchronous pulley is fixedly connected to one end of the outer side wall of the connecting rod, and a synchronous belt is arranged between the first synchronous pulley and the second synchronous pulley.

[0012] As a preferred technical solution of the present application, a fixing block is fixedly connected to one side of the fixing plate, and the top of the threaded rod is rotatably connected to the bottom of the fixing block.

[0015] In the solution of the present application: The driving member drives the mold frame to rotate around the axis of the rotating shaft. The mold frame drives the rotating shaft to rotate on the support column. At this time, the rotating shaft drives the first synchronous pulley to rotate. The first synchronous pulley drives the second synchronous pulley to rotate through the synchronous belt. The second synchronous pulley drives the connecting rod to rotate on the support column and drives the second bevel gear to rotate.
