Description

Technical Field

[0001] This utility model relates to the field of mold temperature controller technology, specifically a mold temperature controller using an indirect heating module. Background Technology

[0002] Mold temperature controllers are widely used in industrial production to control mold temperature and improve production quality. Traditional mold temperature controllers use direct heating, with the heating element in direct contact with water, which easily leads to scale buildup, reduced heating efficiency and heat dissipation, and causes thermal expansion, rapid heating and cooling of the element, affecting its service life. In addition, the traditional structure has uneven heat distribution, and frequent depressurization and water replenishment cause temperature fluctuations, affecting production stability.

[0003] Therefore, there is an urgent need for an improved mold temperature controller structure to enhance heating efficiency and equipment durability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mold temperature controller that employs an indirect heating module, solving the problems of traditional heating in mold temperature controllers. By separating the spiral tube and the heating tube, scale buildup on the surface of the heating tube is avoided, thus improving heating efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold temperature controller employing an indirect heating module, comprising a frame, a water pump fixed at the lower end of the frame, an output end of the water pump connected to a connecting pipe, and the other end of the connecting pipe connected to a separate heating mechanism capable of indirect heating; the separate heating mechanism comprises a spiral tube and a heating tube, the spiral tube being connected to the connecting pipe, the heating tube being located inside the spiral space of the spiral tube, a heating channel being wrapped around the outside of the spiral tube, the heating channel being filled with a die-cast aluminum filler layer, and the die-cast aluminum filler layer having spiral holes matching the spiral tube.

[0006] Furthermore, a reserved hole is provided in the middle of the heating channel, and the reserved hole is matched with the heating tube. After the heating tube is powered on and heats up, it indirectly heats the spiral tube.

[0007] Furthermore: the heating channel is provided with a heat-insulating hollow layer inside, and multiple reinforcing ribs are fixed inside the heat-insulating hollow layer. The reinforcing ribs are made of non-thermal conductive material.

[0008] Furthermore: the heating tube is provided with limiting plates at both ends, and the limiting plates are fixed to the two ends of the heating channel by screws, and multiple heating tubes are evenly distributed between the limiting plates.

[0009] Furthermore, the spiral holes are formed by casting and fit tightly against the surface of the spiral tube, thereby improving heat exchange efficiency.

[0010] Furthermore, the die-cast aluminum filler layer ensures that the heat from the heating tube is evenly transferred to the spiral tube, thereby improving heating efficiency and temperature stability.

[0011] This invention provides a mold temperature controller employing an indirect heating module. Compared with existing technologies, it has the following advantages:

[0012] This mold temperature controller uses an indirect heating module; it employs an indirect heating method, separating the heating element from the spiral tube to avoid scale affecting heating and heat dissipation, thus improving heating efficiency; a die-cast aluminum filler layer enhances heat transfer uniformity and reduces temperature fluctuations; an insulating hollow layer reduces heat loss and improves energy efficiency; reinforcing ribs improve structural stability; a limiting plate fixes the heating element to ensure safe use; the overall structure extends the equipment's lifespan and is suitable for high-precision temperature control requirements.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-4This utility model provides a technical solution: a mold temperature controller using an indirect heating module; specifically, it includes a frame 1, with a water pump 2 fixed at the lower end inside the frame 1. The output end of the water pump 2 is fixedly connected to a connecting pipe 3. The mold temperature controller is existing known technology and will not be described in detail here. The other end of the connecting pipe 3 is connected to a separate heating mechanism, which includes a spiral tube 5 and a heating tube 7. The heating tube 7 is located inside the spiral tube 5, and a heating channel 4 is wrapped around the outside of the spiral tube 5. A reserved hole 8 is opened in the middle of the heating channel 4, and the reserved hole 8 is matched with the heating tube 7. The spiral tube 5 is also installed in the heating channel 4. After the heating tube 7 is powered on and heats up, it heats the spiral tube 5 located outside the heating tube 7. This is different from the traditional heating method. The heating tube 7 is separated from the spiral tube 5, which avoids scale affecting heating and heat dissipation. This not only improves the heating efficiency, but also avoids the rapid rise in tube surface temperature and expansion caused by the decrease in heat dissipation performance. After depressurization, water needs to be added again, which would cause the traditional electric heating tube to cool down rapidly. In this case of rapid heating and cooling, the stainless steel will have a longer service life due to continuous thermal expansion and contraction.

[0020] The interior of the heating channel 4 is filled with a die-cast aluminum filling layer 12. The die-cast aluminum filling layer 12 can improve the heat transfer efficiency of the heating tube 7 and can uniformly heat the spiral tube 5, further improving the heat exchange efficiency. The die-cast aluminum filling layer 12 is provided with a spiral hole 9 that matches the spiral tube 5. The spiral hole 9 is formed by casting, so it fits tightly with the surface of the spiral tube 5, improving the heating and heat exchange efficiency.

[0021] A heat-insulating hollow layer 10 is provided inside the heating channel 4. The heat-insulating hollow layer 10 can reduce the heat loss inside, thereby reducing the probability of heat loss and maintaining the internal temperature at a relatively required temperature. Reinforcing ribs 11 are fixed inside the heat-insulating hollow layer 10. Multiple reinforcing ribs 11 are provided to improve the connection stability between the heating channel 4 and the die-cast aluminum filling layer 12. The reinforcing ribs 11 are made of non-thermal conductive material.

[0022] Limiting plates 6 are provided at both ends of the heating tube 7. The limiting plates 6 are fixed to the two ends of the heating channel 4 by screws. Multiple heating tubes 7 with equal spacing are fixed between the limiting plates 6, thereby maintaining stability and preventing shaking, and improving the safety of the heating tube 7 during use.
