Embodiment Construction

[0022] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] see Figure 2 to Figure 4 , the plasticizing assembly of the injection molding machine of the present invention has a central axis 9 (that is to say, the plasticizing assembly is roughly symmetrical along the central axis 9 ). The plasticizing assembly includes a screw 1 and a barrel (not shown in the figure) that cooperate with each other, wherein a compound mixing head 6 is provided at the top of the screw 1 . The composite mixing head 6 includes: a mixing part 61, which is used to cooperate with the inner wall of the barrel to form a plurality of glue passages, each glue passage can allow the passage of molten rubber and effectively block unmelted The passing of particles; and a splitter 62, which is further extended forward by the front end of the mixing part 61, in order to cooperate with the inner wall of the barrel ...

Abstract

The invention provides an injection molding machine and a plasticizing component thereof. The plasticizing component is provided with a central axis and comprises a screw and a feed cylinder, which are matched with each other, wherein a composite mixing head is arranged at the top end of the screw and comprises a mixing part and a shunting part; the mixing part is used for being matched with the inner wall of the feed cylinder to form a plurality of rubber passing channels; each rubber passing channel can allow melted rubber materials to pass and effectively prevent unmelted particles from passing; the shunting part further extends forward from the front end of the mixing part and is used for being matched with the inner wall of the feed cylinder to form a plurality of shunting channels so that the melted rubber materials are further shunted and mixed. The mixing effects and the injection molding quality can be improved by adopting the injection molding machine and the plasticizing component.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to the structure of a plasticizing component in the injection molding machine. Background technique [0002] see figure 1 , the plasticizing assembly of the injection molding machine has a central axis 9a, and the plasticizing assembly includes a screw 1a and a barrel (not shown in the figure) that cooperate with each other. Wherein, the top end of the screw 1a is provided with a screw head 2a, a non-return ring 3a, a thrust ring 4a and the like. The screw 1a generally has a single-thread structure, a double-thread structure, or a single-thread structure plus a single-structure mixing head at the front end. In the existing structure of plasticizing components, in the plasticizing process of the injection molding machine, there is a phenomenon that the mixing is not complete to a certain extent, and a small amount of incompletely melted pellets still remain during injection; Plastic...
