Problems solved by technology

When closing the mold, mechanical power or hydraulic power is used. The hydraulic power is to use the hydraulic rod to push the piston rod to move to push the cylinder to close the mold. However, the structure in the prior art makes the hydraulic oil push the cylinder for a long time and has low efficiency.

Abstract

The assembly process of the double oil cylinder pushing mechanism for injection molding machine disclosed in the present invention, S1, inserting the first plunger into the first flow cavity in the cylinder body; S2, contacting the side wall of the annular protrusion on the second piston One end surface is coated with abrasive, and then the second piston coated with abrasive is placed into the second flow chamber through the second flow chamber port in the cylinder; S3, the side with abrasive on the second piston and The side wall of the annular protrusion is in close contact with and rotates after applying pressure to the second piston at the same time. The side wall of the annular protrusion and the side with abrasive on the second piston are ground mutually so that the side wall of the annular protrusion and the second piston Sealing is achieved between one side of the piston; S4. Use the third end cover and the sealing ring to close the port of the second flow chamber, and insert the pressurized plunger on the third end cover through the perforation of the second piston In the pressurized chamber at the end of the first plunger. It improves the driving efficiency, and the end surface of the piston has a high tightness with the surface in contact with it.

Description

technical field [0001] The invention relates to the technical field of an oil cylinder assembly process, in particular to an assembly process of a double oil cylinder pushing mechanism for an injection molding machine. Background technique [0002] The function of the clamping system on the injection molding machine is to ensure that the molding mold can be opened and closed flexibly, accurately, quickly, reliably and safely, to ensure that the mold cavity is tightly closed and the plastic melt will not overflow outside the cavity. When clamping the mold, mechanical power or hydraulic power is used. When using hydraulic power, the hydraulic rod is used to push the piston rod to move to push the cylinder to close the mold. However, the structure in the prior art makes the hydraulic oil push the cylinder for a long time and has low efficiency. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to design an assembly process of a double-cylinder pushing ...
