Bottle embryo taking out and cooling system

Abstract

The invention relates to a bottle embryo taking out and cooling system. The system comprises a fixing die and a moving die that are arranged on an injection molding machine and a bottle embryo arranged between the fixing die and the moving die, and further comprises a taking embryo cooling device, wherein the taking embryo cooling device comprises a fixing seat, a first ball linear guideway, a sliding block seat, and a taking out jig that contains a cooling device and a servo motor belt transmission mechanism; the fixing seat is connected with the head plate of the injection molding machine; one end of the fixing seat faces the part between the fixing die and the moving die; the servo motor belt transmission mechanism is arranged on the fixing seat; the first ball linear guideway is arranged on the fixing seat; a first sliding block is arranged on the first ball linear guideway in a sliding manner; the sliding block seat is arranged on the first sliding block, and driven by the servo motor belt transmission mechanism to perform a linear to-and-fro movement on the fixing seat; the taking out jig that contains a cooling bottle embryo and a vacuum extraction bottle embryo is mounted at the front end of the sliding block seat. According to the invention, the system has the characteristics of flexibility for operation, high operating speed, low driving power, small controlling difficulty and stability for operation.

Description

technical field [0001] The invention relates to a preform take-out and cooling system. Background technique [0002] The preform injection molding machine is mainly composed of an injection molding machine and a multi-cavity mold. It is mainly used to produce plastic preforms. The injected preforms are further blow-molded to obtain products such as plastic bottles or medical packs. [0003] The production of the preform injection molding machine is carried out in a repeated cycle according to the process requirements of the product. Shortening the time occupied by each process and adopting the production method of parallel processes as much as possible are effective ways to shorten the cycle time and improve the production efficiency of the preform injection molding machine. [0004] Generally, the traditional preform injection molding machine is not equipped with a three-station preform fetching robot. The preform product can only be released from the mold after cooling an...

Problems solved by technology

[0006] However, because the three-station manipulator is relatively bulky, especially when it is applied to a mold with more than 96 cavities, the removal of the jig is larger and heavier, and the required speed is very high, so the control is very difficult, and the cost of the entire control system is very high.

In addition, due to the large load of the three-station manipulator, the repeated positioning of the end point is unstable, which affects the stability of the preform, and there will be a probability of embryo leakage, which affects the stability of the production system; and with the development of society, the needs of customers make preforms The production cycle time is continuously shortened, and the existing three-station manipulator is difficult to meet the needs of customers
