Problems solved by technology
However, the injection molded part is connected to the solidified waste material in the rubber runner (the interface between the injection molded part and the waste material is usually called the gate, and the gate is the entrance for the injection molded part to receive the plastic raw material), and it usually needs to be cut manually. The waste removal of the gate of injection molded parts is not efficient in manual cutting, and the cutting position is prone to deviation, resulting in uneven product quality

Embodiment Construction
[0015] see figure 1 , the preferred embodiment of the present invention injection molded parts production system includes a molding machine 10, a PLC control module 20 connected to the molding machine 10, an oil transfer module 30 connected to the PLC control module 20, a An oil cylinder module 40 connected to the oil delivery module 30 , a cutter 50 connected to the oil cylinder module 40 and at least one elastic member 60 connected to the cutter 50 .
[0016] see figure 2 , the forming machine 10 includes a male mold 11 , a female mold 12 , an injection module 13 , a pressure holding module 14 and a cooling module 15 . When the molding machine 10 injects a product, the male mold 11 and the female mold 12 are clamped with a mold cavity of a specific shape and size between them; the plastic injection module 13 injects molten plastic raw materials into the mold. In the cavity; the pressure-holding module 14 applies a pressure-holding pressure to the plastic material in the c...

An injection molded part production system comprises: a molding machine, wherein the molding machine executes the steps of injection, pressure maintenance and cooling in order to prepare an injection molded part; a PLC control module connected with the molding machine; an oil convey module connected with the PLC control module; an oil cylinder module connected with the oil convey module; and a cutting knife connected with the oil cylinder module, wherein the PLC control module receives a pressure maintenance fishing signal of the molding machine and then controls the oil convey module to output hydraulic oil to the oil cylinder module, and the oil cylinder module pushes the cutting knife to automatically cut the sprue waste of the injection molded part. The invention also discloses an injection molded part production method based on the injection molded part production system. The injection molded part production system and the injection molded part production method enable the sprue waste of the injection molded part to be automatically cut off before the cooling molding of the injection molded part, so the production efficiency is improved, and the product quality is improved.
Description
technical field [0001] The invention relates to a production system and method of injection molded parts, in particular to a production system and method of injection molded parts which can automatically cut off gate waste of injection molded parts. Background technique [0002] There are usually one or more mold cavities in the mold used for injection molding plastic parts, and each mold cavity is connected with a glue runner. The molten plastic particles flow into the mold cavity through the glue runner, and then go through pressure maintaining and cooling. After the steps, the plastic material in the mold cavity can be solidified and molded, and an injection molded part corresponding to the shape of the mold cavity can be produced. However, the injection molded part is connected to the solidified waste material in the rubber runner (the interface between the injection molded part and the waste material is usually called the gate, and the gate is the entrance for the injec...
