Abstract

The invention provides a mold closing mechanism, which belongs to the technical field of plastic forming and solves the problems of complicated structure, high processing difficulty and high cost of a conventional mold closing mechanism. The mold closing mechanism comprises a fixed template, a back template and a pull rod, wherein a movable template is also glidingly arranged on the pull rod; a mold is arranged between the movable template and the fixed template; one side of the back template is provided with a power mechanism; a through hole is formed in the back template; a top rod is arranged in the through hole in a penetrating way and is connected with the power mechanism; a plurality of rows of clamp teeth are arranged on the peripheral surface of the top rod; the other side of the back template is provided with a locking mechanism; the top rod passes through the locking mechanism and abuts against the movable template; the locking mechanism can tightly lock the clamp teeth; an oil bag sheaths the top rod and is arranged between the locking mechanism and the back template; and after the oil bag is filled with hydraulic oil, the oil bag can push the locking mechanism so that the top rod tightly abuts against the movable template. The mold closing mechanism has the advantages that the structure is simple, the cost is low, and the response speed is high.

Description

technical field [0001] The invention belongs to the technical field of plastic molding and relates to a mold clamping mechanism. Background technique [0002] The mold clamping mechanism is one of the most important parts of the injection molding machine. Its function is to ensure the reliable locking of the molding mold and realize the opening and closing movement of the mold and the ejection of the product. The system rigidity of the mold clamping mechanism affects the quality of the product, the mold clamping speed determines the number of machine cycles, the mold clamping force determines the total energy consumption of the machine, and the structure of the mold clamping mechanism also affects the cost of the whole machine. Therefore, the clamping mechanism directly affects the overall performance and cost of the injection molding machine. [0003] Chinese patent CN102189652A discloses an electric compound mold clamping mechanism, which includes a servo motor, a screw p...
