Automatic material taking device for injection mold

Abstract

The invention discloses an automatic material taking device for an injection mold. A mold set comprises a centre and a mold body for injection molding of a cupped workpiece. A mobile material suckingmechanism comprises a mobile air box and material sucking pipes which are arranged on the side wall of the mobile air box and correspond to a plurality of mold cavities on the mold body one by one; and the interior of the mobile air box is provided with a first air cavity and a second air cavity, a mobile plug plate is connected between the first air cavity and the second air cavity, the materialsucking pipe is in gas communication with the first air cavity, and the second air cavity is connected with air sucking pipes. A material guiding assembly comprises a material abutting plate and a material guiding groove; the material abutting plate is installed on the inner side of the mobile air box through a supporting rod, the side, close to the mold body, of the material abutting plate is connected with a cup abutting ring through a compression spring, and the material sucking pipe penetrates through the material abutting plate; and the material guiding groove is arranged on the lower portion of the corresponding material sucking pipe and used for providing guiding for the cupped workpiece, and an air sucking opening of the air sucking pipe right faces the material guiding groove below. A stacking assembly comprises a plurality of cup stacking barrels corresponding to the tail end of the material guiding groove. Through the automatic material taking device, the material tacking efficiency can be improved, and the pollution to the environment can be reduced.

Description

technical field [0001] The invention relates to the technical field of retrieving devices, in particular to an automatic retrieving device for injection molds. Background technique [0002] For the injection molding process of plastic cup workpieces, the method of mass stamping is generally adopted. When demolding, the cup-shaped workpieces are ejected from the mold cavity with an ejector pin, and then the molded workpieces are transferred one by one by a clamp or manually. There are two defects in the process of retrieving materials: after a large number of plastic cups are taken out, they are usually stacked manually, so that they can be stacked neatly, reduce the floor space, and facilitate batch movement. This method is inefficient; the plastic cups are just out of the film At the same time, because the surface still has residual temperature, it is not conducive to manual transfer, and the hot plastic cup is easy to emit pungent odor and pollute the environment, threaten...

There are two defects in the process of retrieving materials: after a large number of plastic cups are taken out, they are usually stacked manually, so that they can be stacked neatly, reduce the floor space, and facilitate batch movement. This method is inefficient; the plastic cups are just out of the film At the same time, because the surface still has residual temperature, it is not conducive to manual transfer. The hot plastic cup is easy to emit irritating odor and pollute the environment, threatening the physical and mental health of the staff.
