Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a corrugated pipe joint mold. Background Technology

[0002] Drainage pipes are indispensable in industry, agriculture, and people's daily lives. Flexible plastic drainage pipes are widely used due to their ease of installation and flexibility. Because the plastic drainage hose has a corrugated and flexible structure, an injection joint needs to be made at the end of the pipe. The injection joint is formed by pressing the pipe body with an injection mold in one piece. Currently, during the processing of the injection joint, the connection between the corrugated pipe body and the injection joint is easily damaged by the mold, which can cause the finished pipe to leak.

[0003] In existing methods of connecting joints and bellows, workers manually place the bellows into a mold, insert it into the iron core, place the upper template, press it down, and inject adhesive to form the joint, thus connecting the injection-molded joint with the bellows. However, when connecting the bellows body and the joint, injection molding is often performed directly inside the mold. When manually placing the bellows, the position may be incorrect, and the bellows may be damaged when the mold presses down to inject the joint. This cannot reduce the chance of the joint and bellows connecting at the wrong points, leading to the bellows being damaged and resulting in defective products. Therefore, a utility model is proposed to solve the above problems. Utility Model Content

[0016] 1. This utility model has a reasonable structure. By lifting the pressure plate and upper mold on the lower mold, the iron core on one side of the connector seat is removed. After the worker inserts the corrugated pipe into the iron core, the worker connects the iron core to the mold connector and then lowers the pressure plate and upper mold. A positioning mechanism is set up by installing a positioning seat on the lower mold. When the worker inserts the corrugated pipe into the iron core and places it in the lower mold, the positioning mechanism of the positioning seat moves upward through the mold cylinder to position the corrugated pipe properly. Then, the next process begins. The injection head of the upper mold injects glue to connect the connector and the corrugated pipe, thus preventing the corrugated part of the corrugated pipe from being crushed, reducing the occurrence of defective products during production and improving work efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figures 1-5 The bellows joint mold shown includes a mold base 1, a mold cylinder 2 mounted on the upper surface of the mold base 1, a positioning seat 3 provided on the upper surface of the mold cylinder 2, mounting blocks 4 provided on both sides of the upper surface of the mold base 1, mounting rods 5 provided on the upper surface of the mounting blocks 4, a lower mold 6 provided on the upper surface of the mounting blocks 4, an upper mold 7 provided on the upper surface of the lower mold 6, a pressure plate 8 provided on the upper surface of the upper mold 7, a joint seat 9 provided on the upper surface of the lower mold 6, a mold joint 10 provided on one side of the joint seat 9, and an iron core 11 provided at one end of the mold joint 10.

[0025] As a preferred embodiment of this example, Figures 2 to 5As shown, a grinding cylinder 2 is mounted on the upper surface of the grinding base 1. A positioning seat 3 is provided on the upper surface of the grinding cylinder 2. Mounting blocks 4 are provided on both sides of the upper surface of the grinding base 1. Mounting rods 5 are provided on the upper surface of the mounting blocks 4. Mounting grooves are opened at both ends of the upper surface of the mounting blocks 4. Two mounting rods 5 are provided inside the mounting grooves. A lower grinding die 6 is provided on the upper surface of the mounting blocks 4. A positioning hole is opened on the side of the upper surface of the lower grinding die 6 near the grinding cylinder 2. A positioning seat 3 is provided inside the positioning hole. Mounting holes are opened at the four corners of the upper surface of the lower grinding die 6. Mounting rods 5 pass through the interior of the mounting holes. The upper surface is provided with an upper grinding mold 7, and the lower surface of the upper grinding mold 7 has an injection hole. A pressure plate 8 is provided on the upper surface of the upper grinding mold 7. A connector seat 9 is provided on the upper surface of the lower grinding mold 6, and a grinding mold connector 10 is provided on one side of the connector seat 9. A placement groove is provided on the upper surface of the lower grinding mold 6 near the grinding mold connector 10. The connector seat 9 is located inside the placement groove, and a connecting hole is provided in the center of the placement groove. A connecting rod is provided on the lower surface of the connector seat 9, and a connecting rod is located inside the connecting hole. An iron core 11 is provided at one end of the grinding mold connector 10. A grinding mold groove is provided on the upper surface of the lower grinding mold 6 near the grinding mold connector 10. The groove and the mold connector 10 and the iron core 11 are mutually compatible. The upper surface of the positioning seat 3 has two connector slots, which are mutually compatible with the iron core 11. During use, the pressure plate 8 and the upper mold 7 are lifted on the lower mold 6. The iron core 11 is taken out from one side of the connector seat 9. After the worker inserts the corrugated pipe into the iron core 11, the worker connects the iron core 11 to the mold connector 10 and then lowers the pressure plate 8 and the upper mold 7. The mold cylinder 2 drives the positioning seat 3 to move up and down in the positioning hole of the lower mold 6 to place the corrugated pipe in the appropriate position. The injection hole in the mold 7 is used to inject molded joints 10 in the lower mold 6 and upper mold 7 to connect with the bellows. By improving the positioning mechanism by installing a positioning seat 3 on the lower mold 6, when the bellows is manually inserted into the iron core 11 and placed in the lower mold 6, the positioning mechanism of the positioning seat 3 moves upward through the mold cylinder 2 to position the bellows properly. Then, the next process is carried out, and the joint is connected to the bellows by injection of glue through the injection head of the upper mold 7. This prevents the bellows from being crushed, reduces the occurrence of defective products during production, and improves work efficiency.

[0026] The working principle of this practical application is as follows:

[0027] During use, the worker lifts the pressure plate 8 and the upper grinding mold 7 onto the lower grinding mold 6, removes the iron core 11 from one side of the connector seat 9, inserts the bellows into the iron core 11, connects the iron core 11 to the grinding mold connector 10, and then lowers the pressure plate 8 and the upper grinding mold 7. The grinding mold cylinder 2 on the grinding mold base 1 then moves the positioning seat 3 up and down within the positioning hole of the lower grinding mold 6 to position the bellows in the appropriate location. Once the position is correct, the worker inserts the lower grinding mold 6 and the grinding mold inside the upper grinding mold 7 through the injection hole in the upper grinding mold 7. The joint 10 is injection molded and connected to the corrugated pipe. By improving the positioning mechanism by installing a positioning seat 3 on the lower mold 6, when the corrugated pipe is manually inserted into the iron core 11 and placed on the lower mold 6, the positioning mechanism of the positioning seat 3 moves upward through the mold cylinder 2 to position the corrugated pipe properly. Then, the next process is carried out, and the joint is connected to the corrugated pipe by injecting glue through the injection head of the upper mold 7. This prevents the corrugated part of the corrugated pipe from being crushed, reduces the occurrence of defective products during production, and improves work efficiency.
