Injection molding particle combined screen

Abstract

The invention discloses an injection molding particle combined screen. The combined screen comprises a large screen body, wherein a discharging port is formed at a bottom end of the large screen body,two supporting rods are erected in the large screen body, a small screen body is fixedly connected with the centers of the two supporting rods, a positioning ring is arranged at the position, makingcontact with the supporting rods, in the large screen body, the two supporting rods penetrate through the small screen, the two supporting rods are perpendicularly arranged, through holes are formed in the positions, connected with the supporting rods, of the peripheral side of the small screen, a plurality of through holes are formed on the peripheral side of the large screen, a plurality of through holes are formed on the peripheral side of the small screen, the cross section of the large screen is in the shape of an equilateral triangle, and the shape of the small screen is similar to thatof the large screen. The combined screen is advantaged in that a positioning ring is arranged, the positioning ring is arranged at the contact position of the large screen and the small screen, that the small screen can be stably placed in the large screen is guaranteed, and the small screen is prevented from sliding and inclining in the large screen.

Description

technical field [0001] The invention relates to the field of injection molding granule screening, in particular to an injection molding granule combination screen. Background technique [0002] 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. Divided into vertical, horizontal, all-electric. 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] The injection molding machine needs to use a plastic dryer to dry the plastic particles before melting the plastic particles. During the drying process, the small screen is prone to tilt in the large screen during the working process, resulting in the failure of the separation of the dry particles and affecting the work efficiency.
