Abstract

A major injection molding machine comprises a control system mounted on a base, and three injecting devices positioned above a control system and an upper mold plate and arranged in the shape of Chinese character Pin along the length direction of a mold. Each injecting device is provided with a plasticizing device and a feeding device; four mode-locked oil cylinders in a mode-locked part are arranged in a quadrangle shape, wherein, every two mode-locked oil cylinders share one cylinder body; eight tie bars are divided into two parts and respectively connected onto the cylinder body of a mode-locked oil cylinder and an upper mold plate; a moveable mold plate arranged between the upper mold plate and the cylinder body of the mode-locked oil cylinder slides up and down along a guide rail formed by the eight tie bars; a cold runner is fixed on the upper mold plate; the base of a mold stripping device is fixed on the moveable mold plate; four moveable cushion blocks and cushion block oil cylinders are connected under the moveable mold plate through the rail formed by the eight tie bars. The mold is divided into an upper mold and a lower mold, wherein the upper mold in fixed on the cold runner, and the lower mold is connected with the sliding plate of the mold stripping device.

Description

technical field [0001] The invention relates to a solid rubber injection molding machine. Background technique [0002] In the prior art, there are two ways to form solid rubber products: one is to use injection molding for small and medium-sized products, and the injection molding machine currently used has at most two sets of injection devices, and each set of injection devices is limited by the size and strength of steel. , Hydraulic oil pressure and other factors, the injection volume is limited, so it is only suitable for small and medium-sized products. For larger products, it cannot be molded at one time due to insufficient injection volume; the second is to use a flat vulcanizing machine to make large products. The flat vulcanizing machine does not have an injection device, it is manually placed the solid rubber directly into the mold cavity, and the pressure generated by locking the two halves of the mold with the clamping machine makes the rubber fill the entire mo...
