Problems solved by technology

[0004] When the raw material is introduced into the position of the connecting port, because the connecting port is in close contact with the outside air, the temperature will be different, and the raw material will become viscous and agglomerated. Drag it out together, so that certain defects will appear after the model is produced

Embodiment

[0028] as attached figure 1 to attach Figure 7 Shown:

[0029] The present invention provides a heat-extrusion shunting die of the type of anti-bonding and destroying due to temperature difference.

[0030] The split smoothing opening 1a is welded to the outer surface of the upper mold 3a and penetrates each other, the alignment opening 2a penetrates the inside of the upper mold 3a, and the outer surface of the upper mold 3a is equipped with a middle fixed block 4a.

[0031] The diversion smoothing port 1a includes an appropriate amount of sealing rod mm1, a gap layer mm2, a curved angle protection mm3, an auxiliary ejector rod mm4, and a connecting port mm5, the appropriate amount of sealing rod mm1 is connected with the auxiliary ejector rod mm4, and the auxiliary ejector rod The rod mm4 runs through the inside of the gap layer mm2, the outer surface of the gap layer mm2 is pasted with a curved angle protector mm3, the appropriate amount of sealing rod mm1 is located insi...

Abstract

The invention discloses a hot extrusion divergent die capable of preventing temperature difference bonding damage. The divergent die structurally comprises a divergent leveling opening and a correcting opening. The divergent leveling opening is welded to the outer surface of an upper die and communicated with the upper die, when the die and a centering block are corrected through the correcting opening, the die is combined together, when a main supporting rod is moved inwards, a top supporting strip is bent through an inward warping core, a reverse thorn opening is used for driving an outer soft layer to be extruded and moved together, a leveling changing strip installed on the outer soft layer can move together, when a guiding pipe conveys materials to the interior, an elastic layer can change together, the leveling changing strip can reach a certain degree, raw materials can be completely released, an outward pushing force is formed on the leveling changing strip through the input raw materials, the leveling changing strip can slowly cover the lower portion till a gap is filled, a guiding opening can be taken out, during conveying at a seam with the temperature difference, the state of performing infusion and closing at the same time is formed, and the raw materials cannot be dragged out together with the guiding opening.

Description

technical field [0001] The invention belongs to the field of moulds, and more specifically, relates to a heat-extrusion shunting die of a type of anti-temperature difference bonding damage. Background technique [0002] Its hot extrusion splitter mold is composed of upper die, lower die and splitter port. Through the splitter port, the raw material is introduced into the combined splitter channel of the mold, so that it can be formed through the next step of processing. The raw material is stored in it. When a certain amount of heat is introduced. [0003] Based on the inventors' discovery above, the existing hot extrusion splitter die mainly has the following deficiencies, such as: [0004] When the raw material is introduced into the position of the connecting port, because the connecting port is in close contact with the outside air, the temperature will be different, and the raw material will become viscous and agglomerated. They are dragged out together, so that certa...
