Description

Technical Field

[0001] This utility model relates to the field of mold temperature controller technology, and in particular to a heating component for a mold temperature controller. Background Technology

[0002] Mold temperature controllers, also known as mold temperature generators, are critical temperature control devices widely used in high-precision temperature control fields such as plastic molding, die casting, rubber tires, rollers, and chemical reactors. They achieve circulating heat transfer through water or oil temperature controllers and are an important component of temperature control equipment in a broad sense.

[0003] Currently used mold temperature controllers typically employ a heating element design where the heating element is wound around the outer wall of the circulating water pipe. However, because both the heating element and the circulating water pipe have cylindrical outer surfaces, the linear contact between them significantly limits the effective heat transfer area, resulting in low heat transfer efficiency. This forces the heating element to operate at high power for extended periods to compensate for heat loss, leading to energy waste. Furthermore, the gaps between the pipes easily form an air insulation layer, further deteriorating heat transfer performance and potentially causing localized overheating, thus affecting the equipment's lifespan. Current improvements involve increasing the winding density or raising the heating power, but fundamentally improving the contact area is difficult, and excessive winding can cause a surge in fluid resistance, impacting system circulation efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a mold temperature controller heating component that can increase the contact area between the heating tube and the circulating water tube, improve heat transfer efficiency, and is easy to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A heating assembly for a mold temperature controller includes a housing, an installation space inside the housing, and an inlet pipe and an outlet pipe extending to the outside of the housing. The inlet pipe and outlet pipe are connected to a water pipe to form a water flow channel. The water pipe is located within the installation space of the housing, and a heating structure is installed on the outside of the water pipe.

[0007] The heating structure includes a heat-conducting cylinder, which is fixedly installed on the outside of the water pipe. A spiral groove is provided on the outside of the heat-conducting cylinder, and an electric heating tube is spirally arranged and mates with the threaded groove. A clearance opening is provided at the end of the outer shell directly opposite the heating tube.

[0008] Thus, a heating structure is installed on the outside of the water pipe between the inlet and outlet pipes to heat the water inside. Driven by a mold temperature controller, the water flows. The heating structure includes a heat-conducting cylinder located outside the water pipe, and an electric heating element located within a spiral groove. The spiral groove increases the contact area between the electric heating element and the heat-conducting cylinder, allowing heat to be transferred from the heating element to the heat-conducting cylinder, which in turn transfers heat to the water pipe. The surface contact between the heat-conducting cylinder and the water pipe further increases the contact area, improving heat transfer efficiency. Simultaneously, the heat-conducting pipe secures the water pipe, ensuring stable installation. A clearance opening is provided on the outer casing for easy wiring of the electric heating element.

[0009] Preferably, the water pipe is arranged in an "S" shape inside the outer casing, and the heat-conducting cylinder is arranged in the straight section of the water pipe.

[0010] Preferably, the heat-conducting cylinder includes two semi-circular ring cylinders, with connecting ends protruding from the ends of the two semi-circular ring cylinders, and the connecting ends of the two semi-circular ring cylinders facing each other are fixedly connected by screws.

[0011] Preferably, the housing includes a base and a top cover, which are fastened together and fixedly connected by screws.

[0012] Preferably, the base has two reinforcing plates fixedly installed at its inner ends, and the reinforcing plates have perforations that allow water pipes to pass through. The two ends of the heat-conducting cylinder abut against the two reinforcing plates respectively.

[0013] In summary, the heating component of this mold temperature controller has the advantages of increasing the contact area between the heating element and the circulating water pipe, improving heat transfer efficiency, and being easy to use. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0020] like Figure 1-5 As shown, a mold temperature controller heating assembly includes a housing, an installation space is formed inside the housing, and an inlet pipe 1 and an outlet pipe 2 extending to the outside are also provided on the housing. The inlet pipe and the outlet pipe are connected to a water pipe 3 to form a water flow channel. The water pipe is located in the installation space of the housing, and a heating structure is installed on the outside of the water pipe.

[0021] The heating structure includes a heat-conducting cylinder 4, which is fixedly installed on the outside of the water pipe. A spiral groove 5 is provided on the outside of the heat-conducting cylinder. An electric heating tube 6 is spirally arranged and mates with the threaded groove. A clearance opening 7 is provided at the end of the outer shell directly opposite the heating tube.

[0022] Thus, a heating structure is installed on the outside of the water pipe between the inlet and outlet pipes to heat the water inside. Driven by a mold temperature controller, the water flows. The heating structure includes a heat-conducting cylinder located outside the water pipe, and an electric heating element located within a spiral groove. The spiral groove increases the contact area between the electric heating element and the heat-conducting cylinder, allowing heat to be transferred from the heating element to the heat-conducting cylinder, which in turn transfers heat to the water pipe. The surface contact between the heat-conducting cylinder and the water pipe further increases the contact area, improving heat transfer efficiency. Simultaneously, the heat-conducting pipe secures the water pipe, ensuring stable installation. A clearance opening is provided on the outer casing for easy wiring of the electric heating element.

[0023] The electric heating element has an existing structure, which is a spiral structure that matches the spiral groove on the heat-conducting cylinder, making it easy to assemble.

[0024] In implementation, the water pipe is arranged in an "S" shape inside the outer casing, with the heat-conducting cylinder located on the straight section of the water pipe. The "S" shape of the water pipe increases its path within the outer casing, allowing for the integration of multiple heating components and improving heating efficiency. The "S" shape of the water pipe extends the water flow path, increasing heat exchange time; the heat-conducting cylinder is concentrated on the straight section, avoiding uneven heat conduction caused by stress concentration in the curved sections and improving temperature control accuracy.

[0025] In implementation, the heat-conducting cylinder includes two semi-circular ring cylinders 8, with connecting ends 9 protruding from the ends of the two semi-circular ring cylinders. The connecting ends of the two semi-circular ring cylinders facing each other are fixedly connected by screws. The split semi-circular ring cylinder design, connected by screws, allows for quick disassembly or assembly, reducing downtime. By adjusting the tightness of the screws at the connecting ends, it is compatible with a certain range of water pipe diameter variations, improving versatility.

[0026] In implementation, the housing includes a base 10 and a top cover 11, which are fastened together and fixedly connected by screws. This facilitates overall assembly.

[0027] In implementation, reinforcing plates 12 are fixedly installed at both ends of the inner side of the base. The reinforcing plates have through holes that allow water pipes to pass through. The two ends of the heat-conducting cylinder abut against the two reinforcing plates respectively. The reinforcing plates provide bidirectional support for the water pipes and the heat-conducting cylinder, improving the overall stability.

[0028] This solution achieves improved thermal efficiency and reduced energy consumption by reconstructing the contact interface (spiral groove + heat-conducting cylinder to expand the contact area and improve heat transfer efficiency), optimizing the flow channel (S-shaped water pipe to extend the water flow path and increase the heat exchange time), and modular design (split shell / heat-conducting cylinder for easy assembly). It also takes into account the convenience of maintenance and improved structural strength.

[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
