Abstract
The invention relates to a demolding method of injection molding products with pinholes and a pin drawing type mold. The mold comprises a pin drawing plate translation device which is a spring, and the spring is arranged in a sliding block or on a connecting rod. When the mold is opened, firstly, the spring translate the pin drawing plate in a direction vertical to the molding surface of a mold core to remove the drawing pin and the product out of a molding cavity of the mold, and the product is disconnected with a degraded material simultaneously; then, the sliding block slides on a guide rail to drive the pin drawing plate to translate in a direction parallel to the molding surface of the mold core; under the action of a positioning baffle plate, the drawing pin is drawn out of the product and completely separated from the product; and then, an ejector pin plate is pushed, and an ejector pin on the ejector pin plate pushes the degraded material out of a degraded material cavity. In the design of the invention, the injection molding product is completely separated from the degraded material and removed out of the mold, and the manual separation is not needed, thereby reducing the working processes; and the mold core which generally adopts a single-side flow passage design can save materials, thus the production cost can be reduced.
