The invention discloses a vacuum chuck type insert fixing device for an injection mold. The vacuum chuck type insert fixing device comprises a fixed mold and a movable mold, wherein a vacuum chuck isarranged at the bottom of the fixed mold, the bottom of the vacuum chuck communicates with an L-shaped pipeline, a vacuum pump is fixedly installed on the outer side wall of the fixed mold, the otherend of the L-shaped pipeline is connected with the vacuum pump, a hollow rod is vertically connected to the interior of the L-shaped pipeline in a penetrating and sliding mode, a vertical through holeused in cooperation with the lower end of the hollow rod is further formed in the bottom of the fixed mold, an electric push rod is fixedly installed at the inner bottom of the hollow rod, the outputend of the electric push rod is vertically upward, and a vertically-arranged transmission rod is fixedly connected to the top end of the electric push rod. According to the vacuum chuck type insert fixing device for the injection mold, by arranging the hollow rod capable of stretching and retracting freely to be used in cooperation with a vertical pipe-shaped insert, two adjustable arc-shaped abutting blocks arranged on the outer side wall of the upper end of the hollow rod are used for abutting against the inner wall of the vertical pipe-shaped insert, and therefore the vertical pipe-shapedinsert can be fixed, and the application range is wider.
Description
technical field [0001] The invention relates to the technical field of mold processing, in particular to a vacuum suction cup-type insert fixing device for an injection mold. Background technique [0002] Injection molding is a method for the production of industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. During the injection molding process, the product inserts need to be placed in the products with inserts Go to the set position on the mold, and then use the vacuum suction cup to generate negative pressure to adsorb and fix the product insert on the mold. The suction cup is released, the plastic product with inserts is separated from the mold, and the plastic product is removed. The vacuum suction cup of the existing insert fixing device can only fix the inserts of flat products, but cannot be used for the vertical pipe insert...
