Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an environmentally friendly plastic injection molding machine. Background Art

[0002] A plastic processing method in which the plastic is plasticized in the heated barrel of the injection molding machine and then injected into the mold cavity of a closed mold by a plunger or a reciprocating screw to form a product. This method can process products with complex shapes, precise dimensions or inserts, and has high production efficiency. Most thermoplastics and some thermosetting plastics such as phenolic plastics can be processed by this method. The material used for injection molding must have good fluidity to fill the mold cavity to obtain the product. Since the 1970s, an injection molding with a chemical reaction has emerged, called reaction injection molding, and has developed rapidly.

[0003] The patent document with the prior art publication number CN213972264U provides an energy-saving and environment-friendly injection molding machine, including a base, a plurality of fixed rods are fixedly installed on one side of the upper end surface of the base, a mounting plate is fixedly installed on one side surface of each of the fixed rods, a plurality of support columns are fixedly installed on one side surface of the mounting plate, a shock-absorbing spring is fixedly installed on the surface of each of the support columns, and a barrel is fixedly installed on one side surface of each of the support columns. This energy-saving and environment-friendly injection molding machine introduces plastic particles from a feed trough into the barrel, drives the roller to rotate by a rotating motor, fully stirs the plastic particles by setting a spiral stirring blade, crushes larger plastic particles by a plurality of crushing blades, and finally filters the plastic particles by a filter screen set at the bottom end of the barrel, which can effectively crush the plastic particles, accelerate the heating area of ​​the plastic particles, reduce the power loss of the equipment, and improve work efficiency.

[0004] However, the existing injection molding machines first put the materials into the hopper, and then the conveying shaft drives the blades to push the materials forward. The rotation of the conveying shaft will cause the materials in the hopper to vibrate, and the vibrating materials will be squeezed downward. The materials squeeze each other at the inlet, which can easily cause the inlet to be blocked. Once the materials are blocked, they need to be manually unblocked, which will delay the work progress. For this reason, we propose an environmentally friendly plastic injection molding machine. Utility Model Content
