Description

Technical Field

[0001] This utility model relates to the field of ball valve manufacturing technology, and in particular to a high-platform ball valve mold. Background Technology

[0002] The high-platform ball valve is a ball valve with a unique design in its valve body structure. Its key feature is a "high-platform" structure where the valve stem axis and the pipe flange sealing surface are on the same plane or form a specific height difference. This platform is typically located at the connection between the valve body and the pipe flange, increasing the overall height of the valve. This allows for easier alignment with the pipe flange during installation, reducing sealing failures caused by installation errors. Simultaneously, the high-platform design optimizes the internal flow path of the valve, reduces fluid resistance, and facilitates the addition of actuators or other accessories. It is suitable for complex operating conditions such as high pressure, high temperature, and corrosive media, and is widely used in industrial pipeline systems such as petroleum, chemical, and natural gas industries.

[0003] Existing high-platform ball valve molds cannot continuously raise the temperature of the molten metal or plastic inside the gating gate, resulting in insufficient fluidity and defects such as incomplete filling and cold shut, which reduces the molding quality. Furthermore, they cannot keep the mold tightly closed during the production process, which can lead to the mold popping open unexpectedly, making it difficult to ensure the personal safety of operators and the stable operation of equipment, thus lacking safety.

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.

[0030] Reference Figures 1-5The present invention provides an embodiment of a high-platform ball valve mold, including a support platform 1, a lower mold 2 fixedly connected to the top of the support platform 1, an upper mold 3 provided on the top of the lower mold 2, a quick-locking component 15 for improving safety connected between the lower mold 2 and the upper mold 3, a pouring gate 4 penetrating through the interior of the upper mold 3, a heating chamber 5 opened inside the upper mold 3, the heating chamber 5 being located outside the pouring gate 4, and a heating component 6 for improving molding quality connected inside the heating chamber 5;

[0031] The heating assembly 6 includes heating rods 7 and a cover plate 8. Multiple sets of heating rods 7 are connected to the inner wall of the heating chamber 5 to prevent the molten material from cooling and to ensure molding quality. The cover plate 8 is located at the top of the heating chamber 5 to prevent heat loss. A through hole 9 is opened inside the cover plate 8, and a thermocouple 10 is connected inside the through hole 9. One end of the thermocouple 10 is located inside the heating chamber 5 to monitor the temperature inside the heating chamber 5 and achieve precise temperature control.

[0032] Heating assembly 6 also includes mounting plate 11, one end of which is fixedly connected to the outside of cover plate 8. Mounting hole 12 is provided inside mounting plate 11, and screw 13 is slidably connected inside mounting hole 12. Threaded hole 14 is provided inside upper mold 3, and one end of screw 13 is threaded into threaded hole 14 for easy assembly and disassembly. Quick-locking assembly 15 includes fixing blocks 16, with two sets of fixing blocks 16. One end of each set of fixing blocks 16 is fixedly connected to the outside of lower mold 2. Fixing rod 17 is fixedly connected between the two sets of fixing blocks 16. Limiting plate 18 is slidably connected to the outside of fixing rod 17. Limiting plate 18 is provided in two sets, and spring 19 is fixedly connected between the two sets of limiting plates 18. Spring 19 slides outside of fixing rod 17, providing elastic force to achieve quick mold locking. Quick-locking assembly 15 also includes locking plate 20. One end of plate 20 is fixedly connected to the outside of upper mold 3. A limiting groove 21 is opened inside the locking plate 20. The end of the limiting plate 18 away from the fixed rod 17 slides inside the limiting groove 21. A pusher block 22 is fixedly connected to the outside of the limiting plate 18 to push the limiting plate 18 to move. The limiting plate 18 is L-shaped to improve stability. Multiple sets of guide holes 23 are opened inside the top of the lower mold 2. Guide rods 24 are slidably connected inside the multiple sets of guide holes 23. One end of the guide rod 24 is fixedly connected to the bottom of upper mold 3 to guide the upper mold 3 and lower mold 2 to accurately align and prevent misalignment during mold closing. A support frame 25 is fixedly connected to the bottom of support platform 1. A controller 26 is connected to the outside of support frame 25. The controller 26, thermocouple 10 and heating rod 7 are electrically connected to each other to control the operation of heating rod 7 and realize automatic temperature regulation.

[0033] Working principle: When the mold is closed, the upper mold 3 is inserted into the guide hole 23 of the lower mold 2 along the guide rod 24 to achieve precise alignment; at the same time, the push block 22 is pushed, which drives the limiting plate 18 to slide along the fixing rod 17 against the elastic force of the spring 19. When the locking plate 20 is aligned with the limiting plate 18, the push block 22 is released, and the spring 19 pushes the limiting plate 18 into the limiting groove 21 of the locking plate 20, quickly completing the locking and fixing of the upper and lower molds; then, the molten material is injected into the mold cavity through the pouring port 4. Multiple sets of heating rods 7 located in the heating chamber 5 are energized and heat up, continuously heating the outside of the pouring port 4 to prevent the material from cooling; at the same time, the thermocouple 10 monitors the temperature in the heating chamber 5 in real time and feeds the data back to the controller 26. The controller 26 automatically adjusts the working state of the heating rods 7 according to the preset temperature value to ensure temperature stability; after molding is completed, the push block 22 is pushed again to make the limiting plate 18 disengage from the limiting groove 21, so that the mold can be quickly opened and the molded high platform ball valve component can be taken out.
