Problems solved by technology

[0002] The injection molding machine is used to inject the molten plastic fluid into the mold, so that the fluid is solidified and formed in the mold. First, the plastic particles are fed into the heating table through the hopper, and the particles are heated and melted into a fluid. The fluid is transported to the injection head plate through the delivery pipe. In the process, the fluid is injected into the mold through the nozzle of the injection head plate; in the prior art, when the plastic fluid is injection molded by an injection molding machine, when the fluid in the mold gradually increases and does not pass through the nozzle of the injection head plate, it will cause A large amount of fluid in the mold pours back along the nozzle, and when the fluid injection force passing along the injection head plate decreases, the blocking injection speed of the fluid in the nozzle slows down, which slows down the injection molding speed of the plastic fluid by the injection molding machine

Abstract

The invention discloses an injection head plate of an injection molding machine. The injection head plate structurally comprises a base, a mold and a heating table, wherein the mold is arranged on the top of the left side of the base, the heating table is located on the right side of the mold, the heating table is provided with a heating cavity, a feeding hopper, a injection head plate body, a conveying pipe, a nozzle and a blocking mechanism, the heating cavity is located in the heating table, and the feeding hopper is vertically fixed to the top of the left end of the heating table. Due to the fact that a large amount of fluid in the mold flows back along the nozzle, the fluid is blocked through a blocking ring of the blocking mechanism, backflow of the fluid in the mold along the nozzle can be reduced, the jetting speed of the fluid in the nozzle can be increased, and the injection molding speed of the injection molding machine on plastic fluid is increased; and due to the fact that part of the fluid is stuck in the inner wall of a flowing groove, the fluid is gradually solidified on the inner wall of the flowing groove, and the fluid on the inner wall of the flowing groove is removed through a contact block in a push plate, so that the situation that the fluid stays on the inner wall of the flowing groove can be reduced, and flowing and discharging of the fluid along the flowing groove can be accelerated.
