Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] see Figure 1-3 , a pipe production extrusion die with uniform temperature, including a feed pipe 1, the feed pipe 1 is used to enter the liquid PVC plastic material from the extruder into the die, and the feed pipe 1 is far away from the extrusion box 2 One side is provided with an external thread, and the extrusion die is connected with the discharge port of the extruder by setting the external thread. One end of the feed pipe 1 communicates with the ...

The invention discloses an extruding die with the even temperature for pipeline production. The extruding die comprises a feeding pipe. One end of the feeding pipe communicates with the bottom of an extruding box, and a containing cavity is formed in the extruding box. The inner wall of the top of the containing cavity is fixedly connected with the top of a heating device, and a heat-insulating device is fixedly mounted on the side wall of the containing cavity. An extruding pipe is fixedly mounted at the top of the extruding box, and the heating device comprises a shell. A metal heat conductive block is fixedly mounted at the top of an inner cavity of the shell. According to the extruding die, by arranging the heat-insulating device and the heating device, the interior of the containing cavity is heated to enable the temperature inside the containing cavity to be the same, thus the situations that PVC plastic materials for pipeline manufacturing are uneven in temperature in the extruding box, thus the PVC plastic materials of partial areas are cooled and solidified, extruding work is influenced, and consequently the density of the pipe during extruding is not the same, so that breaking is prone to occurring are prevented, and the effect that the quality of the pipe during extruding is improved is achieved.
Description
technical field [0001] The invention relates to the technical field of pipes, in particular to a pipe extrusion die with uniform temperature. Background technique [0002] The pipe production line is an assembly line for pipe production. The main configurations include: automatic feeding machine, single / twin screw extruder, extrusion die, vacuum sizing spray box, tractor, cutting machine, stacker, etc. [0003] Among them, the extrusion die is a device used to extrude the pipe to shape it. The pipe is extruded by the extruder through the extrusion die and passes through the shaping device to form a pipe. The effect when the pipe is extruded from the extrusion die It determines the appearance and thickness of the pipe, so the appearance of the pipe after it comes out of the extrusion die plays an important role in the function and sales of the pipe in the future. [0004] However, the extrusion dies currently on the market have the problem of uneven temperature inside the ex...
