Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the injection head for mold forming includes a material pipe 100, a connecting seat 110 sleeved on the material pipe 100, and a power device 200, wherein the connecting seat 110 is connected with the power device 200, so that the power device 200 can drive the connecting seat 110 to move on the material pipe 100. In this embodiment, the power device 200 includes an air cylinder, and the connecting base 110 is connected to a piston rod of the air cylinder, so that the piston rod of the air cylinder drives the connecting base 110 to move up and down. One end of the material pipe 100 is communicated with the material box.
The material pipe 100 is of an inverted T shape and comprises a vertical feeding section 101 and a horizontal distributing section 102, one end of the feeding section 101 is connected to the side face of the distributing section 102, and the feeding section 101 is communicated with the distributing section 102. And both sides of the material distributing section 102 are provided with through holes, the through holes are connected with a material discharging pipe 130 through a bamboo joint pipe 120, and the material distributing section 102, the bamboo joint pipe 120 and the material discharging pipe 130 are communicated.
