Description

Technical Field

[0001] The utility model relates to the technical field of foaming molds, in particular to a foaming mold for thermal insulation pipes. Background Art

[0002] The mold for foam molding is a plastic foam mold. The foamable resin is directly filled into the mold, heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny nuclei are formed, and the nuclei grow to form foam plastic parts. There are three common foaming methods: physical foaming method, chemical foaming method and mechanical foaming method.

[0003] In the prior art, such as a foaming mold for thermal insulation pipes in Chinese Patent CN 218111491 U, it includes a base.

[0028] The effect achieved by the entire Example 1 is that at the end of foaming, the staff removes the bolt and nut from the through hole 28, removes the upper mold 25, then activates the second electric telescopic rod 17. The telescopic end of the second electric telescopic rod 17 retracts, driving the lower mold 11 to descend. Finally, the staff activates the electromagnet 22, and the iron clamping block 24 is attracted and leaves the clamping groove 20 and enters the limiting groove 21. At this time, the staff can remove the connecting block 19, and then the lower mold 11 can be removed. Clean the inner walls of the upper mold 25 and the lower mold 11, so as to ensure the cleaning quality.

[0029] Example 2, as Figures 1 - 5 shown, further, a support plate 6 is fixedly installed on the outer wall of the workbench 1, a first electric telescopic rod 7 is fixedly installed on the outer wall of the support plate 6, the telescopic end of the first electric telescopic rod 7 penetrates through the support plate 6 and is fixedly installed with a moving plate 5, a fixing plate 4 is fixedly installed on the top of the workbench 1, and circular rings 8 are fixedly installed on the tops of both the fixing plate 4 and the moving plate 5.

[0038] The overall effect achieved by the entire Embodiment 2 is as follows: When installing the steel pipe 9, the worker inserts one end of the steel pipe 9 into the ring 8 at the top of the fixed plate 4, then starts the first electric telescopic rod 7. The telescopic end of the first electric telescopic rod 7 pushes the moving plate 5 to move, so that the other end of the steel pipe 9 enters the ring 8 at the top of the moving plate 5. Finally, the worker rotates the handle 36, and the second threaded rod 34 rotates, causing the second threaded rod 34 to move along the threaded hole 33, driving the abutting block 35 to move until the abutting block 35 contacts the steel pipe 9 and fixes the steel pipe 9. In this way, the fixation of the steel pipe 9 can be completed, preventing the steel pipe 9 from moving during foaming.

[0039] Working principle: When installing the steel pipe 9, the worker inserts one end of the steel pipe 9 into the ring 8 at the top of the fixed plate 4, then starts the first electric telescopic rod 7. The telescopic end of the first electric telescopic rod 7 pushes the moving plate 5 to move, so that the other end of the steel pipe 9 enters the ring 8 at the top of the moving plate 5. Finally, the worker rotates the handle 36, and the second threaded rod 34 rotates, causing the second threaded rod 34 to move along the threaded hole 33, driving the abutting block 35 to move until the abutting block 35 contacts the steel pipe 9 and fixes the steel pipe 9. In this way, the fixation of the steel pipe 9 can be completed, preventing the steel pipe 9 from moving during foaming. When the foaming is completed, the worker removes the bolt and nut from the through hole 28, removes the upper mold 25, then starts the second electric telescopic rod 17. The telescopic end of the second electric telescopic rod 17 retracts, driving the lower mold 11 to descend. Finally, the worker starts the electromagnet 22, and the iron clamping blocks 24 are attracted and leave the clamping grooves 20 and enter the limiting grooves 21. At this time, the worker can remove the connecting block 19, and then the lower mold 11 can be removed to clean the inner walls of the upper mold 25 and the lower mold 11, thus ensuring the cleaning quality. When the cleaning is completed, the motor 13 is started, and the first threaded rod 14 rotates, thereby driving the sliding plate 16 to move along the limiting rod 15 to adjust the translational position of the lower mold 11 in the horizontal direction, and then the production of the foaming layer on the outer surface of the next section of the steel pipe 9 is carried out.
