AI Technical Summary

Technical Problem

During the cooling process, existing vertical injection molding machines are prone to cause internal stress concentration or surface quality problems of the product, and serious energy waste during the injection molding process.

Method used

The cooling system and counterweight mechanism with adjustable cooling rate are adopted to monitor the temperature and flow of the cooling water through a temperature sensor, and the mold separation and closing is controlled by electric push rods to achieve automated injection molding and cooling. The counterweight plate balances the weight of the injection molding mechanism and reduces energy consumption.

Benefits of technology

It realizes efficient cooling control, avoids internal stress concentration and surface quality problems of the product, while reducing energy consumption, improving injection molding efficiency and energy saving effect.

Abstract

The present invention discloses a vertical injection molding machine, belonging to the technical field of injection molding equipment, which includes: a base, an injection molding mechanism and a molding mechanism. The injection molding mechanism includes: an injection barrel and an injection screw. The injection screw is rotatably installed in the injection barrel. A heating ring is fixedly sleeved on the outer side of the injection barrel, and a counterweight mechanism is arranged on both sides of the injection barrel; the molding mechanism includes: a molding die, a fixing plate and a cooling box. A molding groove is arranged on one side of the molding die, and the fixing plate is fixedly installed on the top of the base. The present invention can realize automatic injection molding, forming and blanking through the provided injection molding mechanism and molding mechanism. Through the provided cooling box and cooling pipes, the cooling intensity can be gradually reduced according to the progress of the cooling work, so as to ensure the forming speed and avoid quality problems at the same time. Through the provided counterweight mechanism, the gravity balance of the injection molding raw materials and the injection molding mechanism can be realized, so as to reduce the energy consumed for controlling its lifting, achieving the effect of energy saving.
