Problems solved by technology

However, in the prior art, due to the needs of the process, the nozzle and the feeding end of the molding machine are connected as a whole. Once the number of color lines on the pipeline increases or decreases, the feeding end of the molding machine and the nozzle need to be replaced together. In order to meet the actual production needs, but remove the use cost of adding feed ends with different numbers of nozzles, replacing or maintaining different types of feed ends will consume a lot of manpower and material resources, which will reduce the production efficiency of gas pipes

Embodiment 1

[0024] Such as Figure 1 to Figure 2 As shown, this embodiment includes a molding die 1 and a mandrel 4 matched with the molding die 1, and also includes a ring body 2 arranged in the molding die 1, and the inner wall of the ring body 2 is formed between the outer wall of the mandrel 4. An annular flow channel 3 has an annular groove 6 on the outer peripheral wall of the ring body 2, and has a plurality of colorant outlet holes 5 communicating with the annular groove 6 on the inner peripheral wall of the ring body 2, so that The forming die 1 is provided with a color material inlet hole 7 communicating with the annular groove 6 . In the prior art, the nozzle for distributing the color thread is integrated with the feeding end of the molding machine, so that when the number of color threads is changed in the gas pipe, the two need to be replaced together, which is cumbersome to operate and increases the cost of the color thread dispensing equipment. Cost of use; for this type ...

Embodiment 2

[0030] Such as figure 2 As shown, the distance between the upper surface of the rib and the outer wall of the mandrel 4 in this embodiment is 1 / 5~2 / 5 of the thickness of the flow channel 3 .

[0031] The distance between the upper surface of the rib and the outer wall of the mandrel 4 is set within the range of 1 / 5~2 / 5 of the thickness of the flow channel 3. On the premise that the color line has a certain thickness, the color in the flow channel 3 The material is divided into two parts after being moved out of the groove-shaped structure formed by the two ribs and acting as a guide. That is, the color line close to the inner wall of the ring body 2 is first dissipated and formed, and the color line on the side away from the inner wall of the ring body 2 is formed. The color line is unformed due to slow heat dissipation, and the unformed part continues to be in contact with the material of the gas pipe. Through the mutual extrusion of the two, the distance between the color l...

Abstract

The invention discloses a color ring used for applying color lines on the surface of a PE gas pipe. The color ring comprises a forming mold and a core rod matched with the forming mold. The color ring further comprises a ring body arranged in the forming mold. An annular flow channel is formed between the inner wall of the ring body and the outer wall of the core rod. An annular groove is formed in the outer circumferential wall of the ring body. A plurality of color material outlet holes communicating with the annular groove are formed in the inner circumferential wall of the ring body. A color material inlet hole communicating with the annular groove is formed in the forming mold. A color line applying structure with the forming mold movably matched with the ring body is designed by the inventor, the color ring is provided with the color material outlet holes, and when the gas pipe with the different numbers of color lines is processed and formed, only the ring body needs to be replaced so as to ensure that the number of the color material outlet holes is the same as that of the color lines of a cable to be formed; hence, overall replacement of the feeding portion of a forming machine is avoided, and the processing technology of the cable is optimized; and meanwhile the applying cost of the color lines of the gas pipe is greatly reduced.

Description

technical field [0001] The invention relates to a pipe fitting forming equipment, in particular to a color ring used for distributing color lines on the surface of PE gas pipes. Background technique [0002] PE gas pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE gas pipes, PP-R pipes, and UPVC pipes all occupy a place. Among them, the strong development momentum of PE gas pipes is the most eye-catching. PE gas pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. Vinyl. [0003] The purpose of the multiple color lines set on the outer wall of t...
