Abstract

A demolding device of a plastic tray injection mold fork insert comprises a mold core fixed plate; a tray leg small insert and a tray leg big insert are mounted on the mold core fixed plate; a slide block groove is mounted on the side wall of the mold core fixed plate; a fork slide block is disposed on the slide block groove; a fork insert is disposed on the fork slide block; the fork insert is provided with rib grooves and square-hole blocks; the demolding device is characterized in that an air inlet is disposed on the side wall of the fork insert; an air valve hole is disposed on each square-hole block of the fork insert; an air valve is mounted in the air valve hole; a cooling water path is disposed in the fork insert; the cooling water path is provided with a cooling water hole.

Description

technical field [0001] The invention relates to a plastic pallet injection mold, in particular to a demoulding device for a fork insert of the plastic pallet injection mold. Background technique [0002] In the warehousing and logistics process of various medicines and foods, plastic chemicals, raw materials, etc., plastic pallets are usually required. In order to make the plastic tray high in strength and save materials, square holes arranged at regular intervals will be formed on the upper surface of the plastic tray, and the main body of the tray is formed by reinforcing ribs between the square holes, but to manufacture such a plastic tray, Especially under the fork of the plastic pallet, a bottom plate needs to be set, and the fork insert of the injection mold cannot be directly core-pulled, but the slider under the fork insert must be pulled out first, and then the insert is moved along the slide. The slope of the block slides down gradually, so that the insert comes o...
