Description

Technical Field

[0001] This utility model relates to the field of electric heating equipment technology, and in particular to a plastic-coated heater. Background Technology

[0002] Currently, the main automotive dashboard production line uses slush molding foam dashboard technology. To make this product, the slush molding machine is used to form the skin, the injection molding machine is used to form the resin skeleton, and then the product is finally obtained by injection foaming. This product has a soft surface and has a better appearance and feel compared to hard plastic dashboards.

[0003] The process of forming the outer skin by slush molding includes: ① heating the mold to 220℃~250℃; ② combining the mold with the raw material box and continuously turning it so that the raw material melts and forms on the mold; ③ cooling the mold to 20℃~50℃; ④ moving the mold to the demolding station and the operator completes the demolding.

[0004] In the process of slush molding with heated molds, there are mainly two types of furnaces: electric furnaces and gas furnaces. The air inside the furnace is heated to 400℃~500℃, and then the mold is placed inside for a certain period of time to bake, ultimately raising the mold to the predetermined temperature. In the domestic instrument panel slush molding industry, two types of heating equipment are mainly used. The previous generation of technology used natural gas as a heat source, but due to the need for gas pipelines, it posed many safety risks and has been gradually phased out. Currently, the more advanced slush molding machine is the one developed in Japan, which uses electric heating technology. Although this technology has improved thermal efficiency compared to the previous generation of gas heating technology, it has a limited lifespan. When the heater is damaged, it needs to be replaced promptly; however, the current replacement efficiency of the heater is low, affecting the continuity of production. Utility Model Content

[0005] The main objective of this invention is to propose a plastic-coated heater, which aims to solve the problem of how to improve replacement efficiency.

[0006] To achieve the above objectives, this utility model proposes a slush molding heater for heating slush molding molds, the slush molding heater comprising:

[0007] The furnace body has an interior forming a heating chamber, and the furnace wall of the furnace body forms an installation cavity communicating with the heating chamber.

[0008] A heater assembly is located in the mounting cavity. The heater assembly includes a heater and an insulation component. The heater and the insulation component are arranged sequentially in a direction away from the heating cavity. The heater and the insulation component are connected. The heater is detachably connected to the cavity wall of the mounting cavity. The heating end of the heater is positioned facing the heating cavity so that the heat generated by the heater can be transferred to the mold located in the heating cavity.

[0009] In one embodiment, the heat insulation component includes a heat insulation layer and a pressure plate, with the heat insulation layer connected to the heater and the pressure plate on both sides, and the pressure plate connected to the heater.

[0010] In one embodiment, the pressure plate is provided with a receiving groove for accommodating the insulation layer, and the two sides of the insulation layer abut against the heater and the receiving groove, respectively.

[0011] In one embodiment, the heater includes a body and flash, the number of flashes being at least two, the at least two flashes being respectively disposed on two opposite sides of the body along the width direction, the flashes being detachably connected to the cavity wall of the mounting cavity, the body being connected to the heat insulation component, and the heating end of the body being disposed towards the heating cavity so that the heat generated by the body can be transferred to the mold located in the heating cavity.

[0012] In one embodiment, the furnace body includes a support assembly and a mounting frame. The support assembly is connected to the mounting frame, and the support assembly and the mounting frame enclose the heating cavity. The mounting cavity is formed between any two adjacent support assemblies.

[0013] In one embodiment, the furnace body further includes fasteners, which include bolts and nuts. The nuts are connected to the side of the support assembly facing the heating chamber. A first through hole is provided on the flash, and a second through hole is provided on the support assembly. The bolt passes through the first through hole and the second through hole in sequence and is then threadedly connected to the nut.

[0014] In one embodiment, the support assembly includes a plurality of support beams, which are spaced apart circumferentially along the heating cavity. Each support beam is connected to the mounting bracket, and the mounting cavity is formed between any two adjacent support beams. The number of heater assemblies is the same as the number of mounting cavities and they are arranged in a one-to-one correspondence. The support beams are provided with a second through hole, and the nut is connected to the side of the support beam facing the heating cavity.

[0015] In one embodiment, the furnace body further includes a fixing component connected to the mounting bracket, and the support component, the heater component, and the fixing component are arranged sequentially in a direction away from the heating chamber.

[0016] In one embodiment, the fixing component includes a plurality of fixing beams, the number of which is the same as that of the supporting beams and they are arranged in a one-to-one correspondence. The fixing beams are arranged parallel to the supporting beams, and each fixing beam is connected to the mounting frame.

[0017] In one embodiment, the heater assembly further includes a wire component, the outer wall of which is covered with an insulating protective layer, the wire component being located on the side of the heater away from the insulation component, and the wire component being electrically connected to the heater.

[0018] In this embodiment of the invention, the mounting cavity formed by the furnace wall provides an installation position for the heater assembly, facilitating subsequent installation, maintenance, and disassembly. The heating cavity formed inside the furnace body accommodates the mold. The heating cavity and the mounting cavity are interconnected, allowing heat to be transferred between them, thereby heating the mold during the slush molding process. The furnace body is the outer shell structure of the entire slush molding heater, providing physical support and protection for the internal heating cavity and mounting cavity, ensuring that each component operates in the appropriate position and does not cause unnecessary interference between them. The heater is the core component that generates heat; its main function is to convert electrical energy or other forms of energy into thermal energy to meet the heating requirements of the mold in the slush molding process. The insulation component reduces heat loss. The heater and insulation component are arranged sequentially away from the heating cavity, allowing the insulation component to effectively reduce heat loss. The heat diffuses outwards, and the heating end of the heater is positioned towards the heating chamber, so that as much heat generated by the heater as possible can be transferred to the mold located in the heating chamber, improving the heat utilization efficiency and ensuring that the mold can be heated quickly and evenly, thereby improving the quality and production efficiency of slush molding products. In the design and optimization process of the slush molding heater in this embodiment, the problems that may occur in actual operation and the safety and convenience of personnel are fully considered. The heat insulation component and the heater are integrated and modularized, that is, the heater and the heat insulation component are connected into a whole, thereby ensuring the structural stability and synergy of the heater and the heat insulation component. Furthermore, the heater is detachably connected to the cavity wall of the mounting cavity, so that only the heater needs to be removed during disassembly, without the need to disassemble the heat insulation component separately, which greatly simplifies the disassembly process and saves maintenance time and labor costs. This utility model embodiment adopts an integrated and modular design, tightly connecting the insulation component with the heater. The structure is simple, the manufacturing process is simple, the cost is low, and it is stable and reliable. It effectively reduces heat loss, improving product quality consistency and stability. Furthermore, it eliminates the need to replace the insulation component when changing the heater, reducing the possibility of safety accidents caused by improper operation. It also reduces the number of steps and complexity in the maintenance process, enabling rapid heater assembly and disassembly, improving replacement efficiency. Replacement time can be significantly reduced from 3 hours to 10 minutes, greatly reducing equipment downtime and improving the continuity and efficiency of slush molding production. Especially in large-scale production, it can significantly increase product output per unit time. Attached Figure Description

[0029] Currently, the main automotive dashboard production line uses slush molding foam dashboard technology. To make this product, the slush molding machine is used to form the skin, the injection molding machine is used to form the resin skeleton, and then the product is finally obtained by injection foaming. This product has a soft surface and has a better appearance and feel compared to hard plastic dashboards.

[0030] The process of forming the outer skin by slush molding includes: ① heating the mold to 220℃~250℃; ② combining the mold with the raw material box and continuously turning it so that the raw material melts and forms on the mold; ③ cooling the mold to 20℃~50℃; ④ moving the mold to the demolding station and the operator completes the demolding.

[0031] In the process of slush molding with heated molds, there are mainly two types of furnaces: electric furnaces and gas furnaces. The air inside the furnace is heated to 400℃~500℃, and then the mold is placed inside for a certain period of time to bake, ultimately raising the mold to the predetermined temperature. In the domestic instrument panel slush molding industry, two types of heating equipment are mainly used. The previous generation of technology used natural gas as a heat source, but due to the need for gas pipelines, it posed many safety risks and has been gradually phased out. Currently, the more advanced slush molding machine is the one developed in Japan, which uses electric heating technology. Although this technology has improved thermal efficiency compared to the previous generation of gas heating technology, it has a limited lifespan. When the heater is damaged, it needs to be replaced promptly; however, the current replacement efficiency of the heater is low, affecting the continuity of production.

[0032] After careful examination, the applicant discovered that the current slush molding machine uses a semi-circular ring-shaped heating furnace. Its supporting structure consists of two rings of square beams. The outer ring of square beams is used to fix the insulation cover, and the inner ring of square beams is used to fix the heater. The heater is mounted on the inner ring of square beams via a fixing plate. Under the existing structure, the steps for replacing the heater are: ① Unscrew the bolts of the insulation cover outside the furnace; ② Remove the insulation cover; ③ Remove the insulation cotton filling between the outer and inner ring of square beams; ④ Personnel crawl under the furnace and loosen the bolts between the fixing plate and the inner ring of square beams; ⑤ Remove the fixing plate; ⑥ Personnel crawl out from under the furnace and replace the heater. The steps for installing the heater are the reverse of these steps. This design has many problems, leading to difficulties in maintenance.

[0033] ① The replacement process is cumbersome and extremely time-consuming: The lifespan of electric heaters is generally 2500-4000 hours (based on a two-shift, two-day-off work system, i.e., 9-12 months), and a large number of heaters need to be replaced every year. Currently, a management system of replacing only when damaged is adopted. Each machine (containing 96 heaters) requires approximately 576 hours of maintenance personnel per year (each replacement: 2 people, 3 hours, totaling 2*3*96=576 hours), with a total labor cost of approximately 63,360 yuan. Our factory has 4 machines of the same model, and the annual labor cost is 4*63,360=253,000 yuan. If the cost of replacing heaters is calculated (4 machines * 1400 yuan / heater * 96 heaters = 537,600 yuan), the total reaches 787,600 yuan.

[0034] ② Low safety and poor working environment of maintenance operations: When the heater is damaged, it will affect the quality of the product and the production cycle and needs to be replaced in time. However, due to the design of the heater mounting plate, the heater can only be removed from the bottom of the furnace. The operation method is for the maintenance personnel to crawl into the bottom of the heating furnace to replace it. The working posture is strange and can easily cause body deformation. In addition, because the temperature of the heating furnace cannot be reduced quickly (the furnace working temperature is 500℃) to the working temperature, the operation cannot be carried out in time. Moreover, there is a high risk of operation. The air is not circulated and the working environment is very poor.

[0035] ③ Difficulty in disassembling and assembling insulation cotton: The heater has insulation cotton on the outside. Every time the heater is replaced, the insulation cotton needs to be disassembled and reassembled in order to take it out or put it into the heater. When the insulation cotton comes into contact with human skin, it will cause itching all over the body, and the symptoms can last for several days, which poses a great threat to the health of maintenance personnel.

[0036] The existing heaters suffer from the above problems, resulting in low heater replacement efficiency and severely impacting production continuity.

[0037] The main objective of this invention is to propose a plastic-coated heater to address the problem of improving replacement efficiency.

[0038] Please see Figures 1 to 3In one embodiment of this utility model, the slush molding heater 100 is used to heat the slush molding mold. The slush molding heater 100 includes a furnace body 1 and a heater assembly 2. A heating chamber 11 is formed inside the furnace body 1, and an installation cavity 12 communicating with the heating chamber 11 is formed in the furnace wall of the furnace body 1. The heater assembly 2 is located in the installation cavity 12. The heater assembly 2 includes a heater 21 and a heat insulation component 22. The heater 21 and the heat insulation component 22 are arranged sequentially in a direction away from the heating chamber 11. The heater 21 and the heat insulation component 22 are connected. The heater 21 is detachably connected to the cavity wall of the installation cavity 12. The heating end of the heater 21 is set towards the heating chamber 11 so that the heat generated by the heater 21 can be transferred to the mold located in the heating chamber 11.

[0039] In this embodiment of the invention, the mounting cavity 12 formed in the furnace wall of the furnace body 1 provides an installation position for the heater assembly 2, facilitating subsequent installation, maintenance, and disassembly. The heating cavity 11 formed inside the furnace body 1 is used to accommodate the mold. The heating cavity 11 and the mounting cavity 12 are interconnected, allowing heat to be transferred between them, thereby heating the mold during the slush molding process. The furnace body 1 is the outer shell structure of the entire slush molding heater 100, providing physical support and protection for the internal heating cavity 11 and mounting cavity 12, thus ensuring that each component works in the appropriate position and does not cause unnecessary interference between them. The heater 21 is the core component for generating heat, and its main function is to convert electrical energy or other forms of energy into heat energy to meet the heating requirements of the mold in the slush molding process. The function of the heat insulation component 22 is to reduce heat loss. The heater 21 and the heat insulation component 22 are arranged sequentially in a direction away from the heating cavity 11, so that the heat insulation component 22 can effectively reduce heat loss. The heat diffuses outwards, and the heating end of heater 21 is positioned towards the heating chamber 11, so that the heat generated by heater 21 can be transferred to the mold located in the heating chamber 11 as much as possible, improving the heat utilization efficiency and ensuring that the mold can be heated quickly and evenly, thereby improving the quality and production efficiency of slush molding products. In the design and optimization process of slush molding heater 100 in this embodiment, the problems that may occur in actual operation and the safety and convenience of personnel are fully considered. The heat insulation component 22 and heater 21 are integrated and modularly designed, that is, the heater 21 and heat insulation component 22 are connected into a whole, thereby ensuring the structural stability and synergy of heater 21 and heat insulation component 22. Furthermore, the heater 21 is detachably connected to the cavity wall of the mounting cavity 12, so that only heater 21 needs to be removed during disassembly, without the need to disassemble heat insulation component 22 separately, which greatly simplifies the disassembly process and saves maintenance time and labor costs.

[0040] The technical solution of this utility model adopts an integrated and modular design, which tightly connects the insulation component 22 with the heater 21. The structure is simple, the manufacturing process is simple, the cost is low, and it is stable and reliable. It can effectively reduce heat loss and improve the consistency and stability of product quality. It also eliminates the need to replace the insulation component 22 when replacing the heater 21, reducing the possibility of safety accidents caused by improper operation. It reduces the operation steps and complexity in the maintenance process, realizes the rapid disassembly and assembly of the heater 21, and improves the replacement efficiency. The replacement time can be greatly shortened from the original 3 hours to 10 minutes, which greatly reduces equipment downtime and improves the continuity and efficiency of slush molding production. Especially in large-scale production, it can significantly increase the product output per unit time.

[0041] Please see Figure 2 In one embodiment, the insulation component 22 includes an insulation layer 221 and a pressure plate 222. The insulation layer 221 abuts against the heater 21 and the pressure plate 222 on both sides, respectively. The pressure plate 222 is connected to the heater 21. Specifically, the insulation layer 221 is the core part of the entire insulation component 22. Its main function is to prevent the heat generated by the heater 21 from dissipating outwards, ensuring that as much heat as possible is transferred to the mold, thereby improving heating efficiency, reducing energy consumption, and ensuring the consistency of the molded product's quality. The main function of the pressure plate 222 is to fix the insulation layer 221 to the heater 21, preventing it from shifting or deforming during operation. Through the fixing action of the pressure plate 222, the insulation layer 221 can be secured to the heater 21. The insulation layer 221 is in close contact with the heater 21 and the pressure plate 222 on both sides, minimizing the channels for heat loss and thus improving the insulation effect. Since the insulation layer 221 is located between the heater 21 and the pressure plate 222, it avoids the problem of skin allergies caused by direct contact between maintenance personnel and the insulation layer 221 during installation or disassembly, improving the working environment and allowing maintenance personnel to work directly by hand, thus improving the convenience of the operation. By integrating the heater 21, the insulation layer 221 and the pressure plate 222 into a whole, the tedious steps of disassembling and assembling the insulation layer 221 are eliminated each time, further simplifying the maintenance operation process and improving the convenience and efficiency of maintenance work.

[0042] In this embodiment, the insulation layer 221 can be made of materials with low thermal conductivity, such as insulation cotton, ceramic fiber or glass fiber, to prevent the heat generated by the heater 21 from dissipating outward, ensuring that as much heat as possible can be transferred to the mold, thereby improving heating efficiency, reducing energy consumption, and ensuring the quality consistency of the slush molding product.

[0043] Please see Figure 2In one embodiment, the pressure plate 222 is provided with a receiving groove 2221 for accommodating the insulation layer 221. The two sides of the insulation layer 221 abut against the heater 21 and the receiving groove 2221, respectively. Specifically, the receiving groove 2221 provides a stable installation space for the insulation layer 221. The size and shape of the receiving groove 2221 match the insulation layer 221, ensuring that the insulation layer 221 maintains the correct position and shape after installation. Simultaneously, it forms a good sealing structure with the heater 21 and the pressure plate 222, reducing heat leakage. The design of the receiving groove 2221 also allows the insulation layer 221 to be accurately placed in a predetermined position, preventing displacement or shaking during operation. In this embodiment, to ensure the stability of the integrated structure of the heater 21, insulation layer 221, and pressure plate 222, the heater 21 and pressure plate 222 can be fixedly connected by welding.

[0044] According to one embodiment of the present invention, for ease of installation and maintenance, the heater 21 and the pressure plate 222 can be detachably connected by bolts or snap-fit, thereby facilitating the replacement of the insulation layer 221.

[0045] Please see Figure 2 In one embodiment, the heater 21 includes a body 211 and flash 212. There are at least two flashes 212, each disposed on one side of the body 211 opposite to each other along its width. The flashes 212 are detachably connected to the cavity wall of the mounting cavity 12. The body 211 is connected to the heat insulation component 22. The heating end of the body 211 faces the heating cavity 11, so that the heat generated by the body 211 can be transferred to the mold located within the heating cavity 11. Specifically, the main function of the flash 212 is to achieve a detachable connection with the cavity wall of the mounting cavity 12. This design makes the heater 21 easier and faster to install and remove, without the need for complex tools or cumbersome operations. At least two flashes 212 are respectively disposed on one side of the body 211 opposite to each other along its width. The symmetrical distribution design effectively fixes and positions the main body 211, effectively suppresses vibration transmission, reduces equipment damage and noise caused by vibration, improves the stability and reliability of equipment operation, and prevents the main body 211 from shifting, shaking or deforming during operation. This ensures the stability of the relative position between the heater 21, the furnace body 1 and the mold, and ensures that heat can be evenly transferred to the mold, improving the quality of the slush molding product. The design of the flash 212 also makes the installation and disassembly of the heater 21 simple and quick. During the production process, when the heater 21 needs to be repaired, replaced or adjusted, maintenance personnel can quickly complete the operation without spending a lot of time on complex disassembly and installation work. This can minimize equipment downtime, improve production efficiency and ensure production continuity.

[0046] Please see Figures 1 to 3 In one embodiment, the furnace body 1 includes a support assembly 13 and a mounting frame 14. The support assembly 13 is connected to the mounting frame 14, and the support assembly 13 and the mounting frame 14 enclose a heating cavity 11. The support assembly 13 forms a mounting cavity 12. Specifically, the support assembly 13 and the mounting frame 14 provide stable support for the entire furnace body 1 structure, ensuring the structural strength and stability of the furnace body 1 during operation. At the same time, they also provide accurate installation positions and positioning references for the heater assembly 2 and the mold, ensuring that each component can be correctly installed and work together.

[0047] Please see Figure 2 In one embodiment, the furnace body 1 further includes a fastener 15, which includes a bolt 151 and a nut 152. The nut 152 is connected to the side of the support assembly 13 facing the heating chamber 11. A first through hole 2121 is provided on the flash 212, and a second through hole 1311 is provided on the support assembly 13. The bolt 151 passes through the first through hole 2121 and the second through hole 1311 in sequence and is threadedly connected to the nut 152. Specifically, during installation, the nut 152 is first connected to the side of the support assembly 13 facing the heating chamber 11. The bolt 151 and the support assembly 13 can be fixed by welding, riveting, or other reliable fixing methods to ensure that the nut 152 is fixed and stable on the support assembly 13. The nut 152 fixed on the support assembly 13 provides stable support and positioning for the bolt 151. Then, the bolt 151 is passed through the first through hole 2121 on the heater assembly 2 and the second through hole 1311 on the support assembly 13 in sequence, so that the threaded end of the bolt 151 is threadedly connected to the nut 152. 52 is threaded to securely fix the heater assembly 2 to the support assembly 13. Since the nut 152 is connected to the support assembly 13 on the side facing the heating chamber 11, the bolt 151 is externally mounted. This means that when the heater 21 needs to be disassembled and repaired, the maintenance personnel do not need to enter the furnace body 1. They can simply turn the bolt 151 from the outside of the furnace body 1 to separate it from the nut 152, thus easily removing the heater assembly 2 from the support assembly 13. This external operation method greatly improves the convenience of maintenance, reduces the difficulty and workload of maintenance personnel, and makes it easier and more convenient to regularly inspect the heater assembly 2. It eliminates the problem that maintenance personnel must be below the heating furnace to replace the heater 21, thereby eliminating the risk of the furnace body 1 falling and injuring maintenance personnel, as well as the risk of being burned while working under the furnace, ensuring the safety of maintenance personnel. It also avoids unnecessary twisting and deformation of the body of maintenance personnel during operation, protecting their health.

[0048] According to one embodiment of the present invention, the fastener 15 may also be a limiting pin, thereby realizing the detachable connection between the flash 212 and the support component 13.

[0049] According to another embodiment of the present invention, the burr 212 and the support component 13 can also be detachably connected by snap-fit.

[0050] Please see Figure 1 and Figure 3 In one embodiment, the support assembly 13 includes multiple support beams 131, which are spaced apart circumferentially along the heating chamber 11. Each support beam 131 is connected to a mounting frame 14, and a mounting cavity 12 is formed between any two adjacent support beams 131. The number of heater assemblies 2 corresponds to the number of mounting cavities 12. A second through hole 1311 is provided on each support beam 131, and a nut 152 is connected to the side of the support beam 131 facing the heating chamber 11. Specifically, the main function of the support beams 131 is to fix and install the heater assemblies 2, bear the weight of the heater assemblies 2, and withstand various forces generated during operation, ensuring the stability and integrity of the furnace body 1 structure. In this embodiment, the multiple support beams 131 are evenly arranged circumferentially along the heating chamber 11 and connected to the mounting frame 14 to form a stable frame structure, providing a quasi-supporting structure for the heater assemblies 2. The precise installation position and positioning benchmark, with the interval between each support beam 131 and the adjacent support beam 131 forming an installation cavity 12, allows the heater assembly 2 to be installed in the predetermined position and direction, ensuring a reasonable and stable layout of the heater assembly 2 within the furnace body 1. The number of heater assemblies 2 corresponds to the number of installation cavities 12, ensuring uniform distribution of the heater assembly 2 within the furnace body 1 and uniform heat transfer within the heating cavity 11, avoiding local overheating or uneven heating, thereby improving the quality of the slush-molded products. Furthermore, it makes the equipment installation process more standardized and regulated. During installation, simply install and connect each heater assembly 2 according to the predetermined position and sequence to complete the equipment assembly. This standardized installation process reduces installation difficulty, improves installation efficiency, and facilitates operator training and operation. In this embodiment, the support beam 131 and the mounting bracket 14 can be connected by welding, bolting, or riveting, and this embodiment does not limit the connection. Welding can provide strong connection strength and is suitable for occasions with high requirements for structural stability. Bolting facilitates installation and disassembly and is suitable for occasions that require regular maintenance or replacement of parts. Riveting has good connection tightness and durability and is suitable for occasions with high requirements for sealing.

[0051] In this embodiment, the size and shape of the mounting cavity 12 match the size and shape of the heater 21. The specific size and shape of the heater 21 can be adjusted according to the size and shape of the mounting cavity 12, and vice versa, thereby improving the applicability of the slush molding heater 100. In this embodiment, the number of heater assemblies 2 and the number of mounting cavities 12 can be flexibly adjusted according to actual production needs. This embodiment does not limit this. In this embodiment, the number of mounting cavities 12 on the furnace body 1 is 24. In the prior art, each mounting cavity 12 needs to be equipped with 4 old heaters to meet the requirements of the slush molding process, so a total of 96 old heaters need to be installed, which is a large number and cumbersome to operate. In this embodiment, since the size and shape of the heater 21 match the size and shape of the mounting cavity 12, only 24 heaters 21 need to be set to meet the requirements of the slush molding process. A total of 24 heaters 21 need to be installed, which greatly reduces the number of installations and improves the replacement efficiency and maintenance convenience of the heaters 21.

[0052] Please see Figure 1 and Figure 3 In one embodiment, the furnace body 1 further includes a fixing component 16, which is connected to the mounting frame 14. The support component 13, the heater assembly 2, and the fixing component 16 are arranged sequentially in a direction away from the heating chamber 11. Specifically, the fixing component 16 provides additional support and fixation for the furnace body 1 structure. The fixing component 16, together with the support component 13 and the mounting frame 14, constitute a stable overall structure that can effectively resist various external forces generated during operation, such as the gravity generated by the heater assembly 2, the stress generated by thermal expansion and contraction, and the vibration during machine operation. This reduces the risk of deformation or damage to the furnace body 1 caused by external forces and improves the structural strength and stability of the equipment. In this embodiment, the fixing component 16 and the mounting frame 14 can be connected by welding, bolting, riveting, or other methods.

[0053] Please see Figure 1 and Figure 3In one embodiment, the fixing component 16 includes a plurality of fixing beams 161. The number of fixing beams 161 is the same as that of the supporting beams 131, and they are arranged in a one-to-one correspondence. The fixing beams 161 and the supporting beams 131 are arranged parallel to each other, and each fixing beam 161 is connected to the mounting frame 14. Specifically, the fact that the number of fixing beams 161 and the supporting beams 131 are the same and they are arranged in a one-to-one correspondence ensures that the furnace body 1 is evenly supported and reinforced at all positions, thereby ensuring that the furnace body 1 is subjected to uniform force during operation and avoiding structural deformation due to excessive local force. This prevents damage, and the one-to-one correspondence allows for more accurate alignment of the heater assembly 2 during installation, ensuring a tight and stable connection between the heater assembly 2 and the supporting beam 131 and the fixed beam 161. Furthermore, since the fixed beam 161 and the supporting beam 131 are parallel, the heater assembly 2 can be disassembled and installed through the gap between adjacent fixed beams 161, eliminating the need to adjust the position of maintenance personnel during installation and disassembly, thus providing significant convenience. In this embodiment, the fixed beam 161 and the mounting bracket 14 can be connected by welding, bolts 151, or riveting, etc., and this embodiment does not limit the connection.

[0054] Please see Figure 2In one embodiment, the heater assembly 2 further includes a wire component 23. The outer wall of the wire component 23 is covered with an insulating protective layer 231. The wire component 23 is located on the side of the heater 21 away from the insulation component 22, and is electrically connected to the heater 21. Specifically, the main function of the wire component 23 is to safely and stably transmit electrical energy provided by an external power source to the heater 21 to ensure that the heater 21 can work normally and heat the mold. To ensure safety during use and prevent electric shock accidents, the outer wall of the wire component 23 is covered with an insulating protective layer 231. The insulating protective layer 231 is generally made of materials with good insulation properties, such as polyvinyl chloride, polyethylene, and other plastic materials. These materials have good insulation properties, wear resistance, and corrosion resistance, and can effectively protect the internal wires and prevent them from being damaged. The conductor component 23 is located on the side of the heater 21 away from the insulation component 22, preventing the conductor component 23 from being wrapped by the insulation component 22. This avoids problems such as aging and melting of the insulation protective layer 231 on the outer wall of the conductor component 23 due to high temperature, thus reducing the risk of electrical faults such as leakage and short circuit. It can maintain the good performance of the insulation protective layer 231, reduce the probability of electrical faults, improve the safety and reliability of the equipment, and ensure the safety of the equipment and operators. In this embodiment, the specific installation position of the conductor component 23 can be selected according to actual needs. The conductor component 23 can be electrically connected to the side of the heater 21 away from the insulation component 22, or it can be electrically connected to the side of the heater 21 adjacent to the insulation component 22. This embodiment does not limit this.
