Four-column hydraulic injection molding machine

Abstract

The invention relates to a four-column hydraulic injection molding machine. The four-column hydraulic injection molding machine includes a lower mold system and an upper mold system which are vertically connected through a vertical column system; the lower mold system includes a base and a lower mold lifting and lowering platform, and the base and the lower mold lifting and lowering system are connected through a lower mold lifting and lowering system; the lower part of a vertical column is a guide rod, the lower mold lifting and lowering platform sleeves the guide rod, and the lower mold lifting and lowering platform can be driven by the lower mold lifting and lowering system to perform smooth lifting and lowering movement along the guide rod; the upper part of the vertical column is a lifting and lowering position adjusting rod; the upper mold system is fixed to the lifting and lowering position adjusting rod in a mode of being capable of moving positions by lifting and lowering; andthe upper mold system is internally provided with an upper mold fixing platform, and an injection molding system is arranged on the upper part of the upper mold fixing platform. The four-column hydraulic injection molding machine adopts two sets of lifting and lowering driving devices, meets the high-speed lifting and lowering in an idle phase, and realizes the reliable mold locking in a mold locking phase.

Description

technical field [0001] The invention relates to a vertical injection molding machine, which belongs to electromechanical integration equipment. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various plastic parts. It is a plastic molding equipment integrating machinery, electricity and hydraulic pressure. With the development of modern industry and cutting-edge science and technology, plastic parts are more and more widely used in defense industry, machinery, electrical, aviation, transportation, construction, agriculture, culture and education, health and various fields of people's life. The injection molding method is one of the main molding methods of plastic products. It uses the injection device to inject the melted thermoplastic or thermosetting plastic in the injection barrel into the cavity of the closed molding mold at high pressure and high speed, and then cools and soli...

Problems solved by technology

[0005] At present, the main forms of injection molding machines are horizontal and vertical. In order to meet the injection molding requirements of larger size molds, vertical injection molding machines are generally used; the structure of vertical injection molding machines currently on the market is roughly like the vertical type of Chinese patent publication number CN100548612C Injection molding machine, after the mold is fixed, it moves through the jet nozzle and locks the mold through the lifting hydraulic cylinder. Since the mold clamping force mainly comes from the hydraulic cylinder in such a structural design, the mold clamping force will not be too large and cannot be used for large Injection Molding Requirements for Dimensions
