Description

Technical Field

However, the existing device has certain problems when used and still needs to be continuously improved.

[0003] For example, a rubber injection molding machine disclosed in the utility model with authorization announcement number CN221584423U includes a connecting seat, the bottom of the connecting seat is fixedly connected to a discharge pipe, the bottom of the discharge pipe is fixedly connected to a discharge port, a connecting block is provided on one side of the bottom of the discharge pipe, the bottom of the inner wall of the connecting block is fixedly connected to a spring, the top of the inner wall of the connecting block is fixedly connected to a limiting rod, the top of the limiting rod is a cube, and the bottom is in the shape of a cylinder, the bottom of the limiting rod is slidably connected to a moving rod, the moving rod is adapted to the spring, the bottom of the moving rod passes through the connecting block and extends to the outside of the connecting block, the rubber discharge amount during rubber injection is adjusted by rotating the rotating disk, and three injection heads of different calibers, large, medium and small, are provided on the rotating disk. The most suitable injection head size can be selected according to different application scenarios and product requirements, and the adjustment is quick and convenient.

[0004] After the device adjusts and rotates the rotating disk, the spring will drive the rotating disk upward through its own rebound force. At the same time, after the rotating disk moves upward, the injection head will be connected with the discharge port, and then the clamping block will be released. The clamping block returns to its original position through the rebound force of the torque spring and is re-locked into the clamping slot on the rotating disk to firmly fix the rotating disk. However, both the spring and the torque spring have a certain deformation capacity, and are prone to deformation during long-term use, which in turn leads to a weakening of their elastic force, thereby affecting the adjustment rotation and limit fixation of the rotating disk.

[0011] As a preferred technical solution of the present invention, an outer side wall at one end of the injection port is provided with an external thread.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
