Problems solved by technology
Some injection molding raw materials need to be heated and preheated before being added to the injection mold of the injection molding machine to match the molding of the injection molding. At present, the injection molding feeding cylinder in production does not have the function of heating and preheating. In addition, the injection molding raw materials It must be dried before being added to the injection molding machine. If the raw material containing moisture is used for injection molding, it will have a great impact on the size of the plastic part; currently, after the raw material is dried, it is placed in the box for pumping , so that the raw materials will be in direct contact with the air, especially if the weather is humid, or human errors will make the raw materials wet, so it is very necessary to solve the above problems

The invention provides a feeding system of an injection molding machine. An upper heating barrel can be used for pumping materials by arranging a transitional box. Materials in the transitional box are supplied from an airtight dry storage box which is used for accommodating dried materials and can keep the materials dry. The materials in the airtight dry storage box can be subjected to secondary blow-drying through hot air blowpipes to be further kept dry. A moisture inductor is arranged in the transitional box to induce moisture, and therefore, blow-drying is selectively conducted, and the feeding system is very intelligent. Since a first moisture inductor is arranged in the transitional box to induce moisture, once the moisture is out of limits, material pumping is stopped. In addition, a capacity inductor is arranged for controlling a second solenoid valve to open and close, so that transporting of the materials is controlled.
Description
technical field [0001] The invention belongs to the field of injection molding production, and in particular relates to a feeding system of 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. Existing various plastic parts mainly adopt injection molding machine to carry out injection moulding. Some injection molding raw materials need to be heated and preheated before being added to the injection mold of the injection molding machine to match the molding of the injection molding. At present, the injection molding feeding cylinder in production does not have the function of heating and preheating. In addition, the injection molding raw materials It must be dried before being added to the injection molding machine. If the raw ...
