Quick precise injection platform

Abstract

The present invention discloses a fast precise injection table structure which comprises an injection table head plate component, a glue-injecting tail plate, two glue-injecting oil cylinder components and a glue-melting cylinder component. The glue-injecting oil cylinder components are arranged at two sides of the injection table head component. The glue-injecting tail plate is equipped with an oil motor. The glue-injecting oil cylinder component comprises a cylinder body, the inside of which is provided with a piston cavity which is equipped with a piston rod at the inside, the piston rod is fixedly equipped with a piston, and one end of the piston rod is fixed at the glue-injecting tail plate. The fast precise injection table structure is characterized in that the other side of the piston is equipped with a piston rod without a rod cavity, which extends outside the piston cavity. The additional piston rod of the fast precise injection table structure occupies a certain cubage of the piston cavity and reduces the hydraulic oil quantity of the piston cavity of the part correspondingly, and accordingly, the fast precise injection table structure can reduce the oil return quantity of the piston cavity of the part when glue is injected at a high speed, reduces the oil return speed and further solves the problem of too high noise caused by too high oil return pressure and speed when the original injection table injects the glue at a high speed.

Description

technical field [0001] The invention relates to an injection platform structure of an injection molding machine, in particular to a double-cylinder balanced injection platform structure. Background technique [0002] The injection table mechanism of the injection molding machine is composed of an injection table head plate assembly, an injection tail plate, two injection cylinder assemblies, a melt cylinder assembly and an oil motor. The traditional injection cylinder assembly includes a cylinder body, and a piston is arranged in the cylinder body. Cavity, a piston rod is installed in the piston cavity, a piston is fixedly installed on the piston rod, and one end of the piston rod is fixed on the rubber injection tail plate. The non-piston rod cavity of the injection cylinder will generate excessive noise due to excessive oil return pressure and speed during high-speed injection, which will cause noise pollution to the operating environment.
