[0012] Preferably, a material guide slide is fixedly connected to the bottom of the shaking material touch plate, and the bottom end of the material guide slide slides with the surface of the movable slider to achieve a shaking effect, thereby periodically shaking the mold cavity, reducing the air content in the injection material, and improving the molding quality.

The extrusion force of the material inside the mold is reduced to prevent the material inside the mold from being subjected to excessive pressure and stress deformation.

[0017] (III) Beneficial effects

[0018] The present invention provides a molding die for manufacturing a computer housing, which has the following beneficial effects:

[0019] (1) In the molding mold for manufacturing computer housing, the syringe is docked with the gate mechanism and pressure is applied downward to the mold. The pressure drives the spiral rod to gradually move downward to cooperate with the limiting spiral groove for spiral transmission, so that the concave plate and the concave plate rotate as a whole. At this time, the gate mechanism and the syringe rotate. The centrifugal force during the rotation causes the material injected inside the concave plate and the concave plate to flow to the edge of the mold cavity, thereby increasing the fluidity of the material inside the mold cavity, avoiding imaging defects, and accelerating the material injection efficiency.

[0020] (2) In the molding die for manufacturing computer housings, during the rotation of the mold, the movable slider is stuck inside the rotating track, so that the movable swing plate flips downward under the action of the extrusion force, and the shaking protrusion contacts and supports the outer side of the movable slider, preventing the mold from detaching outward during rotation, thereby ensuring the relative stability of the mold rotation.

[0021] (3) In the molding die used for manufacturing computer housings, the material guide slide gradually presses downward and contacts the inner side of the rotating track during rotation to guide the structure. After the material shaking touch plate contacts the shaking protrusion, the rotational force causes the material shaking touch plate to contact and rub against the surface of the shaking protrusion to achieve a shaking effect, thereby periodically shaking the mold cavity, reducing the air content in the injected material and improving the molding quality.

[0022] (4) In the molding die used for manufacturing computer casings, in the early stage of injecting materials, the top of the ejection pad and the storage pad groove are in a sealed state. As the material contacts the ejection pad and conducts heat to the inside of the sealed air bag, the air pressure inside the sealed air bag gradually increases. At this time, the medium inside the heat conduction card block expands due to the heat, and the heat conduction card block is connected to the inside of the limiting card groove, thereby ensuring the stability of the mold during molding and avoiding the influence of the mechanical structure on the molding shape.

[0023] (5) In the molding die used for manufacturing computer housings, after the material is cooled and formed, the heat conduction block is cooled first in the upper position, so that the heat conduction block shrinks toward the inside of the movable inner groove. At this time, the air pressure inside the sealed air bag is released instantly, and the stabilizing rod drives the material removal pad to bounce upward to form the housing, thereby realizing automatic material removal, facilitating workers' operation, and improving molding efficiency.

[0024] (6) In the molding die used for manufacturing computer casings, when the material passes through the inside of the feed trough, the extrusion pressure of the material will guide the arc plate to flip downward, ensuring smooth material transmission. When the material in the mold is fully injected, the material spreads upward to the bottom of the extrusion touch plate, and as the injection continues, the extrusion touch plate is lifted upward, thereby gradually flipping the elastic sealing plate upward until it flips to a horizontal position. At this time, the material is in a disconnected state, reducing the extrusion force of the material inside the mold, and avoiding stress deformation caused by excessive pressure on the material inside the mold.

[0047] Working principle: install the concave plate 2 and the forming convex die 3, and place the assembled mold in the inner limit of the limiting installation groove 5, dock the syringe with the gate mechanism 4, and apply pressure downward to the mold. The pressure will drive the spiral rod 9 to gradually downward cooperate with the limiting spiral groove 6 for spiral transmission, so that the concave plate 2 and the concave plate 3 rotate as a whole.

As the material contacts the material removal pad 83 and conducts heat to the inside of the sealed air bag 84, the air pressure inside the sealed air bag 84 gradually increases, and at this time, the medium inside the heat conduction card block 86 expands due to the heat, and the heat conduction card block 86 is connected to the inside of the limiting card groove 87 to ensure the stability of the mold during molding and avoid the influence of the mechanical mechanism on the molding shape; after the material is cooled and formed, the heat conduction card block 86 is in the upper position and cooled first, so that the heat conduction card block 86 shrinks to the inside of the movable inner groove 85, and the air pressure inside the sealed air bag 84 is instantly Release, the stabilizing rod 82 drives the material removal pad 83 to bounce up the forming shell, realizing automatic material removal, facilitating workers' operation and improving forming efficiency; when the material passes through the inside of the feed trough 41, the extrusion force of the material will guide the arc plate 42 to flip downward to ensure smooth material transmission. When the material in the mold is fully injected, the material spreads upward to the bottom of the extrusion touch plate 44, and as the injection continues, the extrusion touch plate 44 is lifted upward, thereby gradually flipping the elastic sealing sheet 43 upward until it is flipped to a horizontal position. At this time, the material is in a disconnected state, reducing the extrusion force of the material inside the mold, and avoiding stress deformation of the material inside the mold due to excessive pressure.
