Description

Technical Field

[0001] The utility model relates to the technical field of hoppers of injection molding machines, in particular to a hopper device for an injection molding machine. Background Technique

[0002] For Engel 2300T injection molding machines and Engel 1300T injection molding machines, Matsui dryers and supporting machine tool heat preservation hoppers are adopted. The material particle conveying method is different from the original centralized conveying method. The material particles are conveyed from the drying barrel to the machine tool heat preservation barrel through the self-owned conveying fan of the dryer.

[0003] The original machine tool heat preservation hopper adopted a limit type level gauge. The full cup signal lifted the balance block through the raw materials in the hopper. Since the balance block was lifted, the cam that originally pressed the normally closed contact of the limit switch no longer pressed the limit switch, and the normally closed contact of the limit switch changed from open to closed. The dryer received the full cup signal. With the use of the heat preservation hopper, after a period of use, we found that compared with the original centralized conveying method, the current conveying method has higher requirements for the level induction and sealing effect of the heat preservation hopper. Therefore, in the current situation of the equipment in use, the phenomenon of the material in the heat preservation hopper being emptied often occurs. At the same time, the braking type level gauge is inconvenient to disassemble and assemble. Therefore, improvement is needed. Content of the Utility Model

[0006] Preferably, a pull ring is fixedly connected to the top of the locking pin, and the pull ring is made of stainless steel. Through the setting of the pull ring, it is convenient to pull up the locking pin.

[0007] Preferably, a guiding block is fixedly connected to the lower section of the pin body of the locking pin, and the guiding block is slidably connected to the inside of the installation sleeve. A guiding rod is fixedly connected to the inside of the installation sleeve, and the guiding rod penetrates through the guiding block and is slidably connected to the guiding block. Through the setting of the guiding rod and the guiding block, it has a guiding effect on the locking pin.

[0008] Preferably, a spring is sleeved outside the rod body of the guide rod. One end of the spring is fixedly connected to the guide block, and the other end of the spring is fixedly connected to the inner surface of the mounting sleeve. Through the arrangement of the spring, the elastic force can act on the locking pin through the guide block.

[0009] Preferably, a ball is arranged on the side of the guide block away from the locking pin, and the ball is slidably connected to the inner surface of the mounting sleeve. Through the arrangement of the ball, the relative friction between the guide block and the mounting sleeve can be reduced to a certain extent.

[0010] Preferably, a sealing ring is embedded outside the positioning sleeve, and the sealing ring contacts the mounting sleeve. Through the arrangement of the sealing ring, the sealing performance between the mounting sleeve and the positioning sleeve can be increased.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1.
