Problems solved by technology

[0002] In the known field of injection molding, in the injection production using recycled materials, it is often encountered that the injection port is blocked by iron fragments, which leads to the failure of injection. The technician usually removes it with a lead wire after dismantling the nozzle and heating it.
In order to prevent iron fragments from entering the barrel, some plastic machines put magnet blocks in the hopper to absorb iron fragments. This method can solve the problem of absorbing some iron fragments. However, due to the limitation of the feeding diameter, the magnet is too large and blocks the mouth. The plastic can't get in, the magnet is too small, and the iron fragments that are far away from the magnet can't be sucked. Therefore, the known technology still has the problem of iron fragments entering the barrel

Embodiment Construction

[0008] The invention discloses the magnetic attraction of the injection molding machine hopper, such as figure 1 , 2 As shown, its special diameter is that the periphery 1 of the magnetic attraction is cross-shaped, the edge 11 has a slope, the inner circle 2 is perforated, and the circle 3 with a cavity is formed in the middle, and the magnetic ring 31 is placed in the cavity.

[0009] The magnetic suction of the hopper of the injection molding machine of the present invention, in use, as long as the technician puts the magnetic suction into the feeding port of the injection molding machine, the magnetic ring will generate a magnetic field in the effective range of the feeding port without affecting the feeding, and the plastic will be perforated from the center and the hopper wall into the barrel.

[0010] Those skilled in the art will understand that without departing from the present invention, appropriate adjustments can be made to the disclosed configuration, for exampl...

Abstract

The invention relates to an injection molding machine material hopper magnetic suction device, which has a cross-shaped periphery, wherein the edge portion is provided with an inclination surface, a hole penetrates through the inner circle, the middle is provided with a circle having a concave cavity, and a magnetic ring is placed in the concave cavity.

Description

technical field [0001] The invention relates to the field of plastic injection, in particular to the magnetic attraction of the injection molding machine hopper. Background technique [0002] In the known field of injection molding, in the injection production using recycled materials, it is often encountered that the injection port is blocked by iron fragments, which leads to the failure of injection. The technician usually removes the nozzle with a lead wire after heating it. In order to prevent iron fragments from entering the barrel, some plastic machines put magnet blocks in the hopper to absorb iron fragments. This method can solve the problem of absorbing some iron fragments. However, due to the limitation of the feed diameter, the magnet is too large to block the mouth. Plastics can't get in, the magnet is small, and the iron fragments far away from the magnet cannot be sucked. Therefore, the known technology also has the problem that iron fragments enter the barrel....
