High-precision and high-efficiency injection molding machine

Abstract

The invention provides a high-precision and high-efficiency injection molding machine. The high-precision and high-efficiency injection molding machine comprises a machine body and further comprises amovable mold plate, a fixed mold plate and an injection mechanism. A plurality of pull rods are mounted between the movable mold plate and the fixed mold plate. A combined contracting brake mechanismcorresponding to the pull rods is mounted on the movable mold plate. A nitrogen auxiliary injection device connected with the injection mechanism is mounted at the side end of the machine body. During mold closing, the combined contracting brake mechanism locks the pull rods. the combined contracting brake mechanism comprises a contracting brake cylinder and a plurality of mold locking pistons. The contracting brake cylinder is connected with one mold locking piston. A piston linkage connecting rod is eccentrically hinged between the two adjacent mold locking pistons. The high-precision and high-efficiency injection molding machine provided by the invention is high in mold replacing speed, good in combined mold locking effect and high in reliability and safety coefficient. The whole high-precision and high-efficiency injection molding machine is high in starting speed, stable in injection rate, high in repeating precision, large in mold containing space, high in production efficiencyand stable and reliable in operation.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a high-precision and high-efficiency injection molding machine. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. Horizontal injection molding machines are the most common type of injection molding machines. The mold clamping part and the injection part are on the same horizontal center line, and the mold is opened along the horizontal direction. Its characteristics are: short body, easy to operate and maintain; low center of gravity of the machine,...

AI Technical Summary

Problems solved by technology

The disadvantages are: the installation of the mold is more troublesome, the mold may tilt or fall if the insert is published, and the machine tool occupies a large area

[0003] Traditional industrial PP rubber barrels have a long injection molding processing cycle. Some injection molding machines are highly specialized and can only inject plastic barrels of a specific size. The versatility is poor and cannot meet the processing of rubber barrels of various specifications and sizes. Inconvenient mold disassembly and installation
