Simple and precise mixing device of injection molding machine

Abstract

The invention discloses a simple and precise mixing device of an injection molding machine. The simple and precise mixing device comprises a mixing bin, wherein a fresh material hopper and an old material hopper are arranged above the mixing bin; the fresh material hopper is connected with a fresh material channel; an impeller A is rotationally arranged in the fresh material channel; one end face of the impeller A is connected with a locating rod; the locating rod is sleeved by a locating sleeve; the locating rod and the locating sleeve are connected together by a dowel pin to be capable of rotating together; a driving gear is arranged at the end part of the locating sleeve; the old material hopper is connected with an old material channel; an impeller B is rotationally arranged in the old material channel; a gear shaft is arranged at the end part of the impeller B; and the gear shaft and the driving gear are engaged and matched for transmission, so that the impeller B can rotate with the impeller A. Compared with the prior art, the device is simple in structure and low in manufacturing cost; a fixed quantity of reclaimed waste materials can be added into fresh materials; the resource usage efficiency is improved to the greatest extent; and the proportion of the fresh materials and the waste materials is adjustable.

Description

technical field [0001] The invention belongs to the field of injection molding machine equipment, and in particular relates to a simple and precise material mixing 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. 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 working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plastic that has been plasticized into the molten state (that is, the viscous flow state) into the closed cavity. The process of obtaining product...

Problems solved by technology

Although this method is simple and does not require additional cost, the operation is cumbersome, and each time the raw material is added to the injection molding machine, it needs to be weighed once, which is very troublesome and the time cost is too large
