Pretreatment device for fed materials of injection molding machine

Abstract

The invention discloses a pretreatment device for fed materials of an injection molding machine. The pretreatment device comprises a bottom plate (1), a box body (2) is arranged on the bottom plate, and a feeding hopper (3) is arranged above the box body (2). A plurality of iron-made guiding plates (4) are rotatably arranged on the inner side wall of the box body (2), arranged on the two sides ofthe inner side wall of the box body (2) correspondingly and sequentially distributed in a staggered mode from top to bottom. Structures for iron scrap separation are arranged on the iron-made guidingplates (4). Recycling boxes (8) are arranged on the positions, located on the two sides of the box body (2), of the bottom plate (1), and a discharging pipe (9) is arranged on the position, located atan end opening of the iron-made guiding plate (4) on the lowest position, of the bottom plate (1). According to the pretreatment device for the fed materials of the injection molding machine, iron scraps in the fed materials are automatically removed, iron scrap impurities are prevented from entering an injection molding cavity, the product quality is improved, and meanwhile parts in the injection molding cavity can be protected against being damaged.

Description

technical field

[0001] The invention relates to the technical field of injection molding machine feed material processing, in particular to an injection molding machine feed material pretreatment device. Background technique

[0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction of monomer as raw material, commonly known as plastic or resin, and its composition and shape can be changed freely. Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity.

[0003] Commonly used plastic particles may be mixed with iron filings. If the iron filings cannot be disposed of in time, they will directly e...
