Technical Field

[0001] This utility model belongs to the technical field of complete steel molds for vertical radial extrusion tube making, specifically relating to a complete steel mold for vertical radial extrusion tube making. Background Technology

[0002] The vertical radial extrusion pipe-making die set is a specialized mechanical device primarily used in the pipe manufacturing process. This die system is typically installed vertically and is suitable for high-efficiency and high-precision pipe production. It shapes alloys or steel inside the die through radial extrusion, utilizing the relative movement between the inner and outer dies to achieve uniform pressure on the material, completing the pipe forming under specific temperature and pressure conditions. This complete die set generally consists of multiple components, including an inner die, an outer die, a guiding mechanism, and an ejection device, to ensure smooth production. It is widely used in building materials, metallurgy, petroleum, and chemical industries, and is particularly suitable for manufacturing special pipes with high precision and strength requirements. Furthermore, due to its compact structure and high degree of automation, the vertical radial extrusion pipe-making die set not only improves production efficiency but also reduces labor costs, making it an important piece of equipment in the modern pipe processing field.

[0003] When using a vertical radial extrusion tube forming die, the tube needs to be cooled after it is made. If the waiting time is too long, it will affect the production progress of the next tube. Therefore, the market needs a new device to solve the current problem. Utility Model Content

[0004] The purpose of this utility model is to provide a complete set of steel molds for vertical radial extrusion tube making, so as to solve the problem that when the complete set of steel molds for vertical radial extrusion tube making mentioned in the background art is used, it is necessary to wait for the tube to cool down after it is made. If the waiting time is too long, it will affect the production progress of the next tube. Therefore, the market needs a new device to solve the current problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical radial extrusion tube forming steel mold, comprising an outer mold sleeve, an inner mold disposed on the inner side of the outer mold sleeve, cooling water being added to the inner mold through a water inlet at the upper end, and the cooling water inside the inner mold being discharged through a drain valve at the lower end, the cooling water flowing through a spiral inner tube inside the inner mold, a feed inlet disposed at the upper end of the outer mold sleeve, an mounting bracket installed at the upper end of the feed inlet, connecting columns sleeved on the left and right sides of the mounting bracket, connecting plates fixed at the upper ends of the two connecting columns, threaded holes disposed on the upper ends of the connecting plates at the inner side, a fixing rod fixed at the middle position of the upper end of the mounting bracket, a bolt post installed at the upper end of the fixing rod, a rotating shaft fixed at the lower end of the bolt post, and the rotating shaft sleeved inside the fixing rod.

[0006] Preferably, multiple outer mold sleeves are provided, and the outer mold sleeves are installed by stainless steel bolts B at the inner position.

[0007] Preferably, the outer mold sleeve forms a complete mold cavity after installation.

[0008] Preferably, a support frame is fixed at the lower end of the inner mold, and the support frame supports the main mold body.

[0009] Preferably, the mounting bracket is installed at the upper end of the feed inlet using stainless steel bolts A located at the front and rear positions on the inner side.

[0010] Preferably, a movable pressure plate is provided inside the outer mold sleeve, and the pressure plate is in close contact with the inner wall of the mold cavity and the outer wall of the inner mold. Pulling the connecting plate upward can cause the pressure plate to move.

[0011] Preferably, the lower end of the connecting plate is fixed with connecting posts at the left and right ends, and the connecting plate is connected to the pressure plate through the connecting posts.

[0012] Preferably, the fixing rod is located inside the threaded hole, and the connecting plate moves upward so that the bolt post contacts the threaded hole. The bolt post can be rotated to enter the inner position of the threaded hole.

[0013] Compared with the prior art, this utility model provides a complete set of steel molds for vertical radial extrusion tube making, which has the following beneficial effects: 1. This device has a spiral inner tube inside the inner mold. Cooling water is added to the inner mold through the water inlet at the top of the inner mold. The cooling water enters the spiral inner tube and moves in the spiral inner tube to cool the inner mold. The temperature of the inner mold comes into contact with the pipe, so that the pipe is cooled quickly to meet the demolding standard. The cooling water flows out from the drain valve at the bottom of the spiral inner tube, which can improve the efficiency of pipe making.

[0014] 2. This device has a mounting bracket installed at the upper end of the feed inlet. When the material enters the mold cavity, the mounting bracket can be installed at the upper end of the feed inlet. Pushing the connecting plate downwards causes the pressure plate to move on the outer wall of the inner mold. The movement of the pressure plate compacts the material, forming it into the shape of a tube. Compared with traditional compaction devices, this device is less prone to damage and can save costs.
