Feeding device of injection molding machine

Abstract

The invention relates to an injection molding machine feeding device which comprises a material storage box, a conveying device and a material conveying barrel, a material pumping cover and a material storage cavity are arranged on the material conveying barrel, a material pumping pipe is arranged on the material pumping cover, a material pumping air blower is arranged on the material pumping pipe, the conveying device comprises a spiral propeller, a driving motor and a material conveying pipe fitting, and the material conveying barrel is provided with a communicating opening and a valve assembly. The valve assembly comprises a rotating disc, a driving gear ring and a driving rack, the rotating disc is sleeved with a torsional spring, an embedding groove is formed in the bottom wall of the material storage cavity, a microswitch is fixed to the bottom wall of the embedding groove, a magnet is arranged on the groove wall of the embedding groove, the driving rack is provided with a connecting chain, an air suction hole is formed in the material pumping cover, and a stirring piece is coaxially arranged on the rotating part. According to the automatic feeding device, automatic feeding can be conducted on the multiple injection molding machines at the same time, and convenience is achieved; and by arranging the valve assembly and the microswitch, when the material particles in one material conveying barrel are lacked, the valve assembly automatically opens the communicating opening, the driving motor drives the spiral propeller to rotate, the material particles are automatically supplemented, and great convenience is achieved.

Description

technical field [0001] The present application relates to the field of injection molding equipment, in particular to a feeding device for an injection molding machine. 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. Injection molding machines are divided into vertical, horizontal and all-electric. [0003] Usually, the injection molding machine manually transports the raw materials to a high place, and introduces them into the feeding port of the injection molding machine to realize feeding. [0004] In view of the above-mentioned related technologies, feeding is carried out by personnel. When loading multiple injection molding machines, the feeding efficiency is low and it is inconvenient. Contents of the invention [0005] In order to improve th...
