Injection molding machine with rapid injection capability

Abstract

The invention discloses an injection molding machine with rapid injection capability, an injection mechanism and a mold clamping mechanism. The first bearing is fixedly installed on the inner wall of the outer cylinder, the top of the middle sleeve is fixedly provided with a cover plate, the feeding hopper is set on the cover plate on the top of the middle sleeve, and the upper end of the screw rod is connected with the motor mounting seat through the second bearing , the lower end of the screw rod extends into the middle sleeve, the upper end of the driving rod is connected with the motor mounting seat through the third bearing, and the driving synchronous pulley is connected with the driven synchronous pulley through a transmission belt. The synchronous reverse rotation of the screw rod and the middle sleeve speeds up the running speed of the material particles from the upper hopper to the spray nozzle, reduces the running time, and avoids the phenomenon that the feeding port is easy to be blocked during the fast feeding process. Therefore, the feeding speed of a single feeding port can be increased, thereby improving production efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of injection molding machines, in particular to an injection molding machine with rapid injection capability. Background technique: [0002] The hydraulic injection molding machine is the main automatic equipment for the integration of machinery, electricity and hydraulics to realize injection molding. At present, one of the screw injection molding machines uses the thrust of the screw to quickly inject the plasticized plastic into the closed state at high pressure. In the good mold cavity, the molded products are obtained through fixed molding. In the process of feeding materials, the injection molding machine of this structure relies on the rotation of the driving motor screw to push the plastic to be melted to the injection head. Since a single driving motor drives the wire The speed at which the rod rotates is limited, which results in a slow feeding speed and the phenomenon that the feeding port is eas...

[0002] The hydraulic injection molding machine is the main automatic equipment for the integration of machinery, electricity and hydraulics to realize injection molding. At present, one of the screw injection molding machines uses the thrust of the screw to quickly inject the plasticized plastic into the closed state at high pressure. In the good mold cavity, the molded products are obtained through fixed molding. In the process of feeding materials, the injection molding machine of this structure relies on the rotation of the driving motor screw to push the plastic to be melted to the injection head. Since a single driving motor drives the wire The rotation speed of the rod is limited, which results in slow feeding speed and easy to cause the phenomenon that the feeding port is blocked.
