Novel efficient injection molding machine and rapid forming process

Technical Field

Background

An injection molding machine is also known as an injection molding machine or an injection machine. The main molding equipment is used for manufacturing thermoplastic plastics or thermosetting plastics into plastic products with various shapes by using a plastic molding die. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. The injection moulding machine is similar to the injection syringe for injection, and is a technological process in which the plasticized plastic in a molten state (i.e. viscous state) is injected into a closed mould cavity by means of the thrust of a screw (or a plunger), and the product is obtained after solidification and shaping. Injection molding is a cyclic process, each cycle consisting essentially of: quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, mold opening and part taking. And taking out the plastic part, closing the mold again, and performing the next cycle.

In the actual production process, due to the difference of the temperature of the injection mold, the molding speed and the cooling demolding speed of the injected liquid plastic are different, so that the molding speed and the cooling speed of the injection molding part are not controlled, the cooling demolding efficiency of the injection molding part is lower, and the specification of the produced plastic part needs to be readjusted by replacing the mold after a batch of products is produced.

An effective solution to the problems in the related art has not been proposed yet.

Then, the controller 24 controls the driving motor 72 to start, the driving motor 72 drives the transmission toothed ring 73 to rotate through the driving gear 77, the transmission toothed ring 73 rotates to drive the driven toothed bars 78 to move inside the connecting rod through grooves 413, the driven toothed bars 78 move to drive the jacking plates 71 to move through the transverse moving frame fixing bolts 76 and the transverse moving rods 79, so that the jacking plates 71 are driven to drive the jacking rods 75 to eject the formed injection molding parts from the replaceable movable mold plate 8 in the moving process, the injection molding parts fall from the blanking port 11 to be collected, and the injection molding work of one injection molding part is completed.

The controller 24 controls the steps to be circularly carried out, so that mass large-scale injection molding parts can be manufactured, and the controller 24 can control the whole injection molding machine to circularly work until all the set processes are completely produced by programming the controller 24.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
