Description

Technical Field

[0001] This utility model relates to the field of pipe extrusion, specifically to an extrusion die device for high-gloss surface industrial pipes. Background Technology

[0002] Pipe extrusion dies are core forming tools used in the plastics processing industry for the continuous production of tubular products, and are key components of the extrusion molding process. In existing technologies, pipes are extruded using dies; however, the surface gloss of the pipes cannot achieve high levels, failing to meet the needs of customers with high requirements for pipe brightness. Therefore, those skilled in the art have provided an extrusion die device for high-gloss industrial pipes to solve the problems mentioned in the background art. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an extrusion die device for high-gloss surface industrial pipes, including a die body, an extrusion cavity is provided inside the die body, a water ring is installed at the left end of the die body, the water ring includes a hollow ring and inlets and outlets, a plurality of inlets and outlets are opened on the inner wall of the hollow ring, and the number of inlets and outlets is even, and water inlet pipes and water outlet pipes are respectively installed inside the plurality of inlets and outlets, and the number of water inlet pipes and water outlet pipes is the same, and a temperature sensor is installed on the inner wall of the hollow ring.

[0004] Preferably, the inner diameter of the hollow ring is the same as the diameter of the extrusion chamber.

[0005] Preferably, one end of the water inlet pipe is connected to the water tank via a pump body.

[0006] Preferably, the water tank is equipped with a heating mechanism and a cooling mechanism.

[0007] The technical effects and advantages of this utility model are as follows: This invention uses an inlet pipe to bring water and the outer diameter of the pipe that has just been extruded from the mold body into contact, thereby polishing the surface of the pipe to a mirror finish. At the same time, by controlling the temperature, the friction of the pipe surface is increased, thus making it closely polished with the water ring. Attached Figure Description

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0010] Please see Figure 1 This embodiment provides an extrusion die device for high-gloss surface industrial pipes, including a die body 1. The die body 1 has an extrusion cavity 2 inside. A water ring 3 is installed at the left end of the die body 1. The water ring 3 includes a hollow ring 4 and inlets and outlets 5. The inner diameter of the hollow ring 4 is the same as the diameter of the extrusion cavity 2. A plurality of inlets and outlets 5 are opened on the inner wall of the hollow ring 4, and the number of inlets and outlets 5 is even. Water inlet pipes 6 and water outlet pipes 7 are installed inside the plurality of inlets and outlets 5, and the number of water inlet pipes 6 and water outlet pipes 7 is the same. One end of the water inlet pipe 6 is connected to a water tank through a pump body. A heating mechanism and a cooling mechanism are set inside the water tank. A temperature sensor 8 is installed on the inner wall of the hollow ring 4.

[0011] The working principle of this utility model is as follows: the pipe is extruded and formed through the extrusion chamber 2, and the water in the water tank is transported to the hollow ring 4 through the pump body and the water inlet pipe 6, so that the water and the outer diameter of the pipe just extruded from the mold body 1 are in contact, thereby polishing the surface of the pipe to a mirror finish. Then, the water is discharged through the water outlet pipe 7, so that the water can be recycled. At the same time, the temperature sensor 8 senses the temperature, and the water temperature is controlled by the heating mechanism and the cooling mechanism, which increases the friction of the pipe surface, thereby making it closely polished with the water ring 3.

[0012] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
