Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a novel hydraulic motor control switch. Background Art

[0002] Injection mold is a widely used mold in the plastic industry. It is mainly composed of a pouring system, a guiding system, a forming system, a cooling system and an ejection mechanism. When processing products with complex shapes such as side holes and side concave, it cannot be ejected directly. The product must be ejected through a core-pulling structure or an inclined ejector mechanism, otherwise it is easy to damage the product. With the advancement of mold processing technology, the requirements for product appearance are getting higher and higher. Many products require leather grain effects on the surface, and there must be no injection defects such as ejector marks, burrs, scratches, and scratches. When the number of product teeth is large, the rack structure is too long. Most molds will use an oil motor rubbing structure, but because the oil motor has inertia, it is difficult to control it to be in the starting position every time, and it is difficult to ensure that the position of each product tooth is the same. However, if a servo motor is used, the price is too high, and a controller is required, which is more troublesome to adjust. Utility Model Content
