Abstract

The invention relates to the injection molding process technology of injection molding parts, in particular to a method for mold-unloading and cooling a thin and small injection molding part and a part taking board thereof. The method comprises the following steps of: adding a local air cooling structure to the part taking board, cooling a mold with water to a mold-unloading temperature before unloading the mold and taking the part, and locally cooling the joint of the part and the sprue of the injection molding part after unloading the mold before sucking up in vacuum. Therefore, the problem that the sprue of the product is easily drawn out when the thin and small injection molding part is sucked up in vacuum is solved. Because of the little temperature drop of the mold, the invention greatly improves the production efficiency of the equipment, saves the energy, reduces the cost and increases the economic benefit.

Description

technical field [0001] The invention relates to an injection molding processing technology for injection molded parts, in particular to a mold opening and cooling method for thin and small injection molded parts and a pick-up plate. Background technique [0002] A mobile phone button, made of transparent PC material, its thickness is about 1mm, it is molded by injection molding of multiple parts in one mold, and the injection molded parts after molding are as follows: figure 1 As shown, it includes a button 10 and a sprue 20 connecting the button 10 . The injection molding process is as follows: (1) mold closing; (2) heating to heat the mold to reach the molding temperature; (3) injection; (4) cooling to cool the mold to reach the mold opening temperature; (5) Open the mold and pick up the parts. The mold opening is picked up by a manipulator through a vacuum pick-up plate, and the pick-up plate is as figure 2 , image 3 As shown, the channel plate 1, the vacuum suction...
