Description

Technical Field

[0001] The utility model relates to the technical field of extrusion moulds, in particular to an extrusion mould which is convenient for material feeding. Background Art

[0002] At present, some plastic products are produced by extruders. The working principle of the extruder is to pass the molten plastic through the extrusion die with huge thrust to form the same shape as the mold cavity, and then cool it to form. Extrusion processing allows simple models to be quickly formed in one piece with high efficiency. However, during the extrusion process, unloading and changing molds often cause trouble to users. Now most molds are formed in one piece, which brings inconvenience to users when changing molds. Utility Model Content

[0003] In order to solve the technical problems of the prior art, the utility model provides an extrusion die which is convenient for material feeding.

[0004] The specific scheme of the utility model is as follows: an extrusion mold that is easy to unload, including a molding mechanism, a cooling mechanism and a main body mechanism, the molding mechanism is located inside the main body mechanism, and the cooling mechanism is located inside the main body mechanism; the molding mechanism includes a first bottom plate, the upper surface of the first bottom plate is fixedly connected to a first contraction spring, the upper surface of the first bottom plate is fixedly connected to a first support rod, the upper surface of the first bottom plate is fixedly connected to a push rod, and the lower surface of the first bottom plate is plugged with a second support rod.

[0005] During the upward pushing process, the first spring contracts, and the first base plate is pushed upward as the first support rod retracts. A second support rod is arranged on the lower surface to strengthen the supporting force between the first base plate and the main main board, thereby increasing the overall stability of the mechanical equipment. The push rod can quickly demold the product after it is formed.

[0006] Furthermore, the outer wall of the push rod is fixedly connected with a lower extrusion groove, the lower surface of the lower extrusion groove is plugged with a second contraction spring, and the outer wall of the lower extrusion groove is fixedly connected with a first fixing nut. During use, the upper and lower extrusion grooves can be quickly removed by removing the fixing nut, and the extrusion groove can be quickly replaced and repaired. When the extrusion groove is fixed, the second contraction spring contracts to provide an upward supporting force to the fixed extrusion groove. When the fixing nut is removed, the contraction spring stretches and resets to give the extrusion groove an outward thrust, thereby preventing the extrusion groove from being stuck due to long-term operation and work and making it difficult to remove.

[0007] Furthermore, the upper surface of the lower extrusion groove is clamped with the upper extrusion groove. The upper and lower extrusion grooves are symmetrically arranged to clamp each other during the extrusion process to reduce the gap, so that the gap of the manufactured product can be reduced due to the defects caused by the mold crack.

[0008] Furthermore, the cooling mechanism includes a cooling pipe, one end of which is threadedly connected to a water inlet, and the other end of which is threadedly connected to a water outlet. The cooling pipe adopts a circulating water cooling system, which takes away the heat in the mold and speeds up the product molding time.

[0009] Furthermore, a heat-conducting copper plate is fixedly connected to the upper surface of the upper extrusion groove, and a second fixing nut is threadedly connected to the upper surface of the heat-conducting copper plate. The heat-conducting copper plate is fixed to the mold by the nut and fits tightly to accelerate the heat transfer and the cooling and molding speed. When the heat-conducting copper plate transfers the heat to the colloid in the mold, the colloid is quickly molded, which speeds up the overall work efficiency.

[0010] Furthermore, the main body mechanism includes a feed port, the lower surface of which is fixedly connected to an upper extrusion plate, the interior of the upper extrusion plate is plugged with a third support rod, and the outer wall of the third support rod is plugged with a lower extrusion plate. The upper extrusion plate and the lower extrusion plate are combined to increase the pressure during the molding process and reduce the gap of the mold. The third support rod limits the position of the extrusion plate as the outer wall of the third support rod is compressed, reducing the errors and defects caused by the mold not being completely closed.

[0011] Furthermore, the lower surface of the lower extrusion plate is fixedly connected to a support plate, the lower surface of the support plate is fixedly connected to a main body bottom plate, and the lower surface of the main body bottom plate is provided with an extrusion opening.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The first bottom plate is fixedly connected to the first support rod by setting the first bottom plate, and the first spring contracts during the upward pushing process, and the first bottom plate is pushed upward as the first support rod retracts. The second support rod is set on the lower surface of the first bottom plate to strengthen the supporting force between the first bottom plate and the main bottom plate, thereby increasing the overall stability of the mechanical equipment. The push rod can quickly demold the product after the product is formed. The first fixing nut is set to fix the upper and lower extrusion grooves. When repairing and replacing the extrusion groove, the first fixing nut can be removed to quickly replace and maintain the extrusion groove;

[0014] 2. By setting the cooling pipe as a circulating water cooling system, the heat in the mold is taken away by the water cooling system, which speeds up the product molding time. The cooling pipe adopts a circulating water cooling system, which takes away the heat in the mold by water cooling, which speeds up the product molding time. The heat-conducting copper plate is fixed on the mold by nuts and fits tightly to speed up the heat transfer. When the heat-conducting copper plate transfers the heat to the colloid in the mold, it quickly forms, improves the product molding speed, speeds up the work speed and improves work efficiency.
