Problems solved by technology

[0002] Injection mold is a molding mold widely used in the production of plastic products. When the plastic products are demoulded after molding, an ejector device is required to separate the product from the mold. The existing ejector structure is common The product is ejected through the ejector plate and the ejector pin. At the same time, the ejector plate is usually driven by a nitrogen spring to drive the ejection movement of the ejector plate of the fixed mold. The service life of the nitrogen spring is short, and fatigue failure is prone to occur during use, and nitrogen The elastic pressure of the spring is very large, causing the ejector plate to be ejected rapidly during the ejection process, and there is a risk of tearing on the barb part of the product

Abstract

The invention discloses a drag hook structure of an instrument panel mold. The drag hook structure comprises an ejector plate (1), an ejector block is arranged below the ejector plate (1), a connecting block (2) is arranged on the ejector plate (1), a pull rod (3) is hinged to the connecting block (2), and a wear-resistant block (4) is arranged on the outer side wall of a movable mold (100); a drag hook (5) is arranged at the end, far away from the connecting block (2), of the pull rod (3); the upper surface of the drag hook (5) is provided with a containing groove (51), and the wear-resistantblock (4) is limited in the containing groove (51); and when the mold is opened, the movable mold (100) moves downwards to drive the pull rod (3) to move downwards together, so that the ejector plate(1) is driven to move downwards along with the inclined ejector block to eject the product. The drag hook structure of the instrument panel mold is used for driving the ejector plate (1) to do ejecting movement, and is capable of stably driving the ejector plate (1), high in precision and long in service life.
