Further, a pressing mother is provided outside the die.

Further, the die is integrally formed with the outer die.

Further, the connecting body includes a connecting body and a docking body integrally formed with the connecting body, the connecting body is fixed to the outer mold, the melt flow channel is provided on the docking body, and the split hole penetrates the connecting body and extends until the docking body communicates with the molten material flow channel.

Further, the connecting body of the connecting body is provided with a receiving hole outward on the inner wall of each distribution hole, and a flow control rod is housed in each receiving hole. Adjust the flow control rod to extend into the split hole to change the size of the split hole, so as to adjust the flow of the molten material in the split hole.

As mentioned above, the extrusion head of the present invention includes at least two sets of extrusion dies, through which at least two heat-shrinkable tubes can be extruded simultaneously, which improves the extrusion speed and efficiency of the heat-shrinkable tubes.

Detailed ways

In order to describe the technical content, objectives and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the extruder head of the present invention includes an outer mold 10 , two core molds 20 , two dies 30 and a connecting body 40 .

Two open mold cavities 11 are provided on the outer mold 10 , and a core mold 20 is fixed inside each open mold cavity 11 . One end of the core mold 20 protrudes from the open cavity 11 , and one end of the core mold 20 protruding from the open cavity 11 is covered with a die 30 fixed to the outer mold 10 . The other end of the outer mold 10 opposite to the mouth mold 30 is fixed with a connecting body 40 .

The connection body 40 includes a connection body 41 and a mating body 42 integrally formed with the connection body 41 . The connection body 41 is fixed with the outer mold 10 . A melt channel 421 is provided at the center of the docking body 42 . The connection body 41 is provided with two distribution holes 411 penetrating through the connection body 41 and extending to the connection body 42 to communicate with the melt channel 421 . The distribution holes 411 communicate with an open cavity 11 respectively.

The core die 20, the die 30 and the outer die 10 form two sets of extrusion dies.

Further, the die 30 is provided with a pressing female 50 outside.

Further, the connecting body 41 of the connecting body 40 is provided with a receiving hole 412 on the inner wall of each distribution hole 411 outward, and each receiving hole 412 accommodates a flow control rod 60 . Adjusting the flow control rod 60 to extend into the split hole 411 can change the size of the split hole 411 , thereby adjusting the flow rate of the molten material in the split hole 411 .

Of course, the die 30 can also be integrally formed with the outer die 10 .

The extruder head of the utility model is connected with the extruder through the docking body 42 of the connecting body 40, and the molten material of the extruder enters into the split hole 411 respectively through the molten material flow channel 421 of the connecting body 40, and then enters the two outer molds 10 The open cavity 11 is used to extrude two heat-shrinkable tubes under the joint action of the two outer molds 10 and the two core molds 20, which improves the extrusion speed and efficiency of the heat-shrinkable tubes.
