Gas ejection die structure for shortening forming period

Abstract

The invention discloses a gas ejection die structure for shortening the forming period. The gas ejection die structure sequentially comprises a fixed die base plate, a fixed template, a movable template, square iron, an ejector pin plate, an ejector pin bottom plate and a movable die base plate from top to bottom. A first cooling water way is arranged in the fixed template, and a second cooling water way is arranged in the movable template. A plurality of first vertical gas guiding rods and a plurality of second vertical gas guiding rods are further included. A first transverse gas path is arranged in the movable die base plate, a second transverse gas path is arranged in the fixed die base plate, the ejector pin plate is provided with a plurality of ejector rods, and the movable templateis internally provided with ejector blocks corresponding to the multiple ejector rods in a one-to-one manner. The gas ejection die structure has the beneficial effects that the structure is compact and simple, and installation is easy; when a formed product is ejected out, stress is more uniform, and the ejection precision is higher; and during die sinking, the formed product is not prone to adhering into the fixed template, the die sinking efficiency is higher, formed product ejection is easier, the ejection time is shortened, and accordingly the forming period is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an air cap mold structure which shortens the molding cycle. Background technique [0002] In daily life, many products use plastic products, such as cars, TVs, mobile phones, etc. These plastic products are all injection molded parts through mold injection molding. Some injection molded parts are structural parts installed inside the product, and some injection molded parts are It is the functional parts that play special functions in the product, and most of the injection molded parts are appearance parts installed outside the product. For these exterior molding products, transparent PP materials are often used for injection molding because of the aesthetic requirements for their exterior surfaces, and ejector pin marks are not allowed on the product surface. If the traditional ejector pin is used to eject the molded product, it cannot be achieved. Appearance requiremen...
