Description

Technical Field

[0001] This application relates to the field of casting equipment technology, and in particular to a one-time curing oven and casting curing production equipment. Background Technology

[0002] In fields such as polymer material molding, including pot-type insulators, curing ovens are commonly used to heat and cure molds or products to ensure that the material undergoes physical or chemical changes under specific temperature conditions to achieve the expected performance requirements. Curing ovens typically employ a whole-body heating method, where the mold is heated by hot air circulation or radiation from the top of the oven. However, in actual production, curing ovens cannot control the curing speed of different parts of the mold, affecting product quality and easily leading to stress concentration and uneven heating, thus impacting product consistency and yield. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a one-time curing oven and casting curing production equipment to improve curing quality and reduce stress defects.

[0004] This application provides the following technical solution: This application embodiment provides a primary curing oven, the primary curing oven comprising: A furnace body module, the furnace body module including a furnace body, the furnace body having a curing cavity; A top heating module is disposed at the top of the furnace body and is used to provide heat to the top area of ​​the curing oven cavity; A bottom heating module is disposed at the bottom of the furnace body and is used to provide heat to the bottom area of ​​the curing furnace cavity.

[0005] In some embodiments of the first aspect, the top heating module and / or bottom heating module includes one or more of an infrared heating tube assembly, a hot air circulation assembly, or a resistance heating assembly.

[0006] In some embodiments of the first aspect, the top heating module and the bottom heating module are each electrically connected to an independent temperature control module, which is capable of adjusting the heating temperature of the corresponding heating module.

[0007] In some embodiments of the first aspect, the bottom heating module includes at least one resistance heating component and a support component, both of which are disposed within the curing oven cavity. The support component is connected to the bottom of the curing oven cavity, the resistance heating component is disposed on the support component, and the support component forms at least one heat dissipation channel, all of which are connected to the curing oven cavity.

[0008] In some embodiments of the first aspect, when the number of the resistance heating components is at least two, all the resistance heating components are arranged at intervals.

[0009] In some embodiments of the first aspect, the curing oven cavity has an inlet / outlet direction, and all the resistance heating components are spaced apart along the inlet / outlet direction.

[0010] In some embodiments of the first aspect, the resistance heating assembly includes at least one heating rod and a heat-conducting block, the heat-conducting block and the support assembly being detachably connected, the heat-conducting block having at least one mounting channel, and a heating rod being disposed in each mounting channel.

[0011] In some embodiments of the first aspect, the heat-conducting block has a plurality of channels that are connected in communication with the curing oven cavity.

[0012] In some embodiments of the first aspect, the furnace module further includes an anti-collision component located within the curing oven cavity and disposed on the periphery of the furnace body to prevent the inner wall of the furnace body from being impacted or scratched.

[0013] Secondly, this application also provides a casting and curing production equipment, which includes a primary curing furnace as described in any of the above embodiments.

[0014] The embodiments of this application have the following advantages: This application provides a single-stage curing oven that achieves precise and uniform temperature field management for molds or products during the curing process through independent zone heating control. The top heating module at the top of the oven and the bottom heating module at the bottom can work together to raise the overall temperature of the curing cavity, meeting basic curing requirements. More importantly, these two modules can independently control and adjust their heat output. In actual curing processes, due to factors such as rising hot air, mold structure, or material properties, there are often natural differences in heat loss between the top and bottom of the mold, leading to uneven heating. This design, through the bottom heating module, can specifically provide additional, controllable heat supplementation to the bottom area of ​​the curing cavity, effectively compensating for the lack of heat loss at the bottom. By adjusting the heating power of the top and bottom separately, the heating situation of the entire mold can be dynamically balanced, ensuring that all parts of the mold are at the same or optimal process temperature, thereby achieving synchronous and balanced curing from top to bottom and controlling the curing speed of different parts.

[0015] Therefore, compared to traditional integral heating curing ovens, this application significantly improves heating uniformity. By using an independent bottom heating module to precisely compensate for the heat in the bottom area, which is prone to low temperatures, it fundamentally improves the uniformity of temperature distribution within the curing oven cavity, effectively solving the uneven heating problem of "hot at the top and cold at the bottom" in traditional methods. In particular, while the curing oven is set to a fixed temperature, the bottom heating module's set temperature is higher than the oven's set temperature. This means the temperature at the bottom of the mold is higher than the temperature at the top, allowing the bottom material to cure first, while the material from the top gate is fed into the mold cavity to improve quality.

[0016] Because the curing speed of each part of the mold tends to be uniform, the shrinkage and internal stress distribution of the material during the curing process are more even. This greatly reduces the risk of stress concentration caused by temperature differences and asynchronous curing, thereby reducing the occurrence of stress defects such as product deformation and cracking, and improving the mechanical properties and dimensional stability of the product.

[0017] Clearly, a more uniform curing process means more stable and reliable product quality across batches and even different batches. Good product consistency and a significantly reduced defect rate directly improve the production pass rate and lower production costs. A uniform temperature field ensures that the material can complete its physical or chemical changes under its optimal process temperature conditions, allowing key performance indicators such as the degree of crosslinking and curing of the polymer material to reach their best state, ultimately improving the overall curing quality of the product.

[0018] Furthermore, for molds of different shapes, sizes, or materials, the curing curve can be optimized by adjusting the parameters of the top and bottom heating modules, enhancing the equipment's adaptability to different production processes and making its application more flexible.

[0028] In related technologies, such as polymer material molding (e.g., for pot-type insulators), curing ovens are commonly used to heat and cure molds or products to ensure that the material undergoes physical or chemical changes under specific temperature conditions to achieve the expected performance requirements. Curing ovens typically employ a whole-body heating method, where the mold is heated by hot air circulation or radiation from the top of the oven body. However, in actual production, curing ovens cannot control the curing speed of different parts of the mold, affecting product quality and easily leading to stress concentration and uneven heating, thus impacting product consistency and yield.

[0029] As shown in Figure 1, Figure 2 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides a primary curing oven, which includes an oven body module 100, a top heating module, and a bottom heating module 200. The oven body module 100 includes an oven body 110, which has a curing cavity. The top heating module is disposed at the top of the oven body 110 and is used to provide heat to the top area of ​​the curing cavity. The bottom heating module 200 is disposed at the bottom of the oven body 110 and is used to provide heat to the bottom area of ​​the curing cavity.

[0030] Please see Figure 1 , Figure 1 This diagram illustrates the structure of a primary curing oven according to an embodiment of the present invention. This primary curing oven is used for the post-cast curing treatment of molded products (such as pot-type insulators in power equipment) made of polymer materials (such as epoxy resin). By independently controlling the temperature in different zones, it achieves gradient heating and temperature uniformity control of the mold or product, thereby reducing internal stress and improving product consistency and yield.

[0031] In these embodiments, the primary curing oven includes an oven body module 100, a top heating module, and a bottom heating module 200.

[0032] The furnace body module 100 includes a furnace body 110, exemplarily constructed of an insulating material (such as aluminum silicate fiberboard) forming a closed curing cavity. The curing cavity is used to accommodate molds or products to be cured (e.g., pot-type insulator molds). A closable furnace door (not shown) is provided on one side of the furnace body 110 for easy insertion and removal of molds. The structure of the furnace body 110 ensures good thermal insulation performance, reduces heat loss, and improves energy efficiency.

[0033] The top heating module is located at the top of the furnace body 110, in the area above the curing chamber. The top heating module includes multiple top heating units, such as electric heating tubes or infrared radiation heaters, evenly arranged on the inner wall of the top of the furnace body 110. The top heating module is connected to the control system via an independent temperature control circuit, enabling it to provide controllable heat to the top area of ​​the curing chamber according to a preset program. For example, in this embodiment, the maximum heating power of the top heating module is 3kW, allowing for precise temperature adjustment within a range of 20°C to 200°C, with a temperature control accuracy of ±1°C.

[0034] The bottom heating module 200 is disposed at the bottom of the furnace body 110, located in the lower region of the curing cavity. The bottom heating module 200 includes multiple bottom heating units, such as heating plates or heating wires, embedded or fixed to the bottom platform of the furnace body 110. The bottom heating module 200 is also connected to the control system via an independent temperature control circuit to provide controllable heat to the bottom region of the curing cavity. For example, in this embodiment, the maximum heating power of the bottom heating module 200 is 5kW, and it has the same temperature adjustment range and temperature control accuracy as the top heating module.

[0035] Optionally, in this embodiment, the top heating module and the bottom heating module 200 adopt an independent temperature control design. The control system (not shown) can set the heating temperature curves for the top and bottom separately according to the curing process requirements. For example, in the early stage of curing, the bottom heating module 200 can be started first to slowly preheat the bottom of the mold to avoid stress caused by rapid curing of the bottom resin; then the temperature of the top heating module is gradually increased to achieve gradient curing from bottom to top. This regional heating method effectively improves the problems of large temperature difference between the top and bottom and inconsistent curing speed caused by traditional overall heating, and significantly reduces the internal thermal stress and shrinkage deformation of the product.

[0036] In addition, the primary curing oven may also include temperature sensors, such as thermocouple sensors, which are respectively set in the top and bottom areas of the curing oven cavity to monitor the temperature in real time and feed the signal back to the control system to achieve closed-loop temperature control, thereby further improving temperature uniformity and process repeatability.

[0037] Furthermore, for example, the heating power ratio of the top heating module and the bottom heating module 200 is adjustable, for example, the bottom heating power is greater than the top heating power, in order to meet the curing requirements of bottom thick-walled structural products such as basin insulators, to ensure that the thick-walled part is fully cured, while preventing the top thin-walled area from overheating.

[0038] Therefore, by setting independent top heating modules and bottom heating modules 200, the primary curing oven provided in this application achieves zoned heating and independent temperature control of different areas within the curing oven cavity. This solves problems such as stress concentration and product deformation caused by uneven heating in the prior art, improving the curing quality and production qualification rate of polymer material products. In particular, the curing oven is set to a fixed temperature, and the set heating temperature of the bottom heating module 200 is higher than the set heating temperature of the curing oven. That is, the temperature at the bottom of the mold is different from the temperature at the top, allowing the bottom material to cure first, and the material from the top gate to be fed into the mold cavity to improve quality.

[0039] In some embodiments, the top heating module and / or bottom heating module 200 includes one or more of an infrared heating tube assembly, a hot air circulation assembly, or a resistance heating assembly 210.

[0040] In these embodiments, the top heating module and / or bottom heating module 200 may employ a combination of various heating methods or be used individually to accommodate the curing requirements of different materials and products. Specifically, the heating module includes one or more of an infrared heating tube assembly, a hot air circulation assembly, or a resistance heating assembly 210.

[0041] In one embodiment, the top heating module includes multiple infrared heating tubes evenly arranged on the inner top wall of the furnace body 110. The infrared radiation emitted by the infrared heating tubes acts directly on the surface of the mold or product, achieving rapid, non-contact heating, which is particularly suitable for processes with high surface curing requirements or sensitive to air disturbance. The bottom heating module 200 may also be equipped with infrared heating tubes for directional heating of the bottom surface of the mold.

[0042] In another embodiment, the top heating module and / or bottom heating module 200 integrates a hot air circulation assembly. This assembly includes a blower (not shown), air ducts, and air outlets. Heated air circulates within the furnace cavity via the blower, achieving convective heating of the mold. Hot air circulation helps improve the temperature uniformity within the furnace cavity, which is particularly suitable for large or complex molds. For example, circulation ducts can be provided on the side wall of the furnace body 110, working in conjunction with the top or bottom heating elements to form a hot air circulation path in the vertical or horizontal direction.

[0043] In another embodiment, the bottom heating module 200 employs a resistance heating component 210, such as a heating plate or heating wire embedded in the bottom platform of the furnace body 110. Resistance heating heats the bottom of the mold through direct heat conduction, resulting in high thermal efficiency and fast temperature control response. The top heating module can also be in the form of a resistance wire coil, combined with a reflector to enhance the heating effect.

[0044] Furthermore, the heating module can also employ a combination of various heating methods. For example: The top heating module is equipped with both an infrared heating tube assembly and a hot air circulation assembly. It uses infrared heating to achieve rapid heating and then uses hot air circulation to balance the temperature. The bottom heating module 200 mainly uses the resistance heating component 210, supplemented by the local infrared heating tube component, to enhance the heating of the thick-walled area of ​​the mold.

[0045] In one embodiment, the heating power ratio of the top heating module and the bottom heating module 200 is adjustable, for example, the bottom heating power is greater than the top heating power, to meet the curing requirements of bottom thick-walled structural products such as basin insulators, to ensure that the thick-walled part is fully cured, and at the same time to prevent the top thin-walled area from overheating.

[0046] In some embodiments, the top heating module and the bottom heating module 200 are each electrically connected to an independent temperature control module, which can adjust the heating temperature of the corresponding heating module.

[0047] In these embodiments, the top heating module and the bottom heating module 200 employ independent temperature control. Specifically, the top heating module and the bottom heating module 200 are each electrically connected to an independent temperature control module, which is used to monitor and adjust the heating temperature of the corresponding heating module in real time, thereby achieving regional, high-precision temperature control.

[0048] For example, the first temperature control module is electrically connected to the top heating module, and the second temperature control module is electrically connected to the bottom heating module 200. Each temperature control module includes a temperature signal acquisition unit, a control logic unit (such as a PID controller), and a power output unit. The temperature signal acquisition unit acquires real-time temperature data through temperature sensors located in corresponding areas within the curing oven cavity (e.g., the first thermocouple T1 is located in the top area, and the second thermocouple T2 is located in the bottom area); the control logic unit compares the measured temperature with a preset temperature curve, calculates the control deviation, and adjusts the current or voltage supplied to the corresponding heating module through the power output unit, thereby dynamically adjusting the heating power to achieve closed-loop temperature control.

[0049] In one embodiment, the operator can pre-set process parameters such as the heating rate, holding temperature, and holding time for the top and bottom areas via a human-machine interface (such as a touchscreen). The control system generates independent temperature control commands based on these parameters, which are then executed by the corresponding temperature control modules. For example, in the curing process of a basin-type insulator, the bottom area can be set to slowly heat up to 80°C at a rate of 1.5°C / min and hold for 2 hours, while the top area can be heated to 60°C at a rate of 0.8°C / min and held for 1 hour. This achieves a gradient curing strategy of heating the bottom first and then gradually heating the top, effectively avoiding internal stress concentration and cracking defects caused by excessive temperature differences between the top and bottom.

[0050] Of course, the temperature control module supports multiple control modes, including constant temperature control, programmed temperature rise control, and segmented temperature hold control. Its temperature control accuracy can reach ±1℃, and the temperature uniformity (maximum temperature difference in the furnace) is less than ±3℃, meeting the process requirements for precision curing of polymer materials.

[0051] Furthermore, the heating module can also employ a combination of various heating methods. For example, the top heating module is equipped with a hot air circulation assembly. The bottom heating module 200 uses a resistance heating assembly 210.

[0052] In some embodiments, the bottom heating module 200 includes at least one resistance heating component 210 and a support component 220. Both the support component 220 and the resistance heating component 210 are disposed inside the curing oven cavity. The support component 220 is connected to the bottom of the curing oven cavity. The resistance heating component 210 is disposed on the support component 220, and the support component 220 forms at least one heat dissipation channel 221. All heat dissipation channels 221 are connected to the curing oven cavity.

[0053] In these embodiments, the bottom heating module 200 includes not only the resistance heating component 210, but also a support component 220 for supporting the mold and optimizing heat transfer. The support component 220 is fixedly connected to the bottom of the curing oven cavity. The resistance heating component 210 is disposed on the support component 220 and heats the mold placed on the resistance heating component 210 by heat conduction.

[0054] The support assembly 220 may be made of a metal material with good thermal conductivity (such as stainless steel or aluminum alloy), and the upper surface of the resistance heating assembly 210 forms a support surface for stably placing the mold. The resistance heating assembly 210 may be, for example, a heating plate, a heating rod, or a heating wire.

[0055] Crucially, at least one heat dissipation channel 221 is formed inside or in the structure of the support component 220. The heat dissipation channel 221 penetrates the support component 220, and its two ends are respectively connected to the curing oven cavity, forming an internal air circulation path. For example, the heat dissipation channel 221 can be designed as a longitudinal through hole, a transverse air duct, or a grid-like cavity structure penetrating the support component 220.

[0056] During the heating process, hot air can flow between the upper and lower areas of the support component 220 through the heat dissipation channel 221, breaking up local heat accumulation and improving the overall temperature uniformity in the furnace cavity. When it is necessary to reduce the bottom temperature or prevent overheating, the heat dissipation channel 221 can accelerate the diffusion of heat to the upper part of the furnace cavity or the circulating airflow, and work with the temperature control module to achieve a more sensitive temperature response. While ensuring structural strength, setting up heat dissipation channels 221 can reduce the amount of material used in support components 220, thereby reducing equipment cost and weight.

[0057] For example, multiple heat dissipation channels 221 are evenly distributed in an array on the support component 220, which ensures both load-bearing capacity and uniform heat dissipation. All heat dissipation channels 221 are connected to the curing oven cavity to ensure smooth airflow and avoid the formation of closed dead zones.

[0058] Furthermore, the heat dissipation channel 221 can also work in conjunction with the hot air circulation components inside the furnace body 110. When the blower is started, hot air is forced to circulate in the furnace cavity, and part of the airflow can pass through the heat dissipation channel 221 and the support component 220 to achieve convective heating of the bottom of the mold, making up for the limitations of pure conduction heating, accelerating the heating rate, and further improving temperature uniformity.

[0059] In some embodiments, when the number of resistance heating components 210 is at least two, all resistance heating components 210 are arranged at intervals.

[0060] In these embodiments, when the number of resistance heating components 210 is at least two, all resistance heating components 210 are arranged at intervals. For example, two, three or more heating rods or heating plates may be provided, evenly distributed along the length or width direction of the support component 220, and maintaining a certain distance from each other.

[0061] Multiple spaced heating components can form multiple independent heating zones on the support component 220, avoiding heat concentration in a single location, effectively reducing local overheating or temperature gradients, and making the bottom of the mold more evenly heated.

[0062] Each resistance heating element 210 can be connected to an independent temperature control submodule to achieve zoned temperature control. For example, different heating powers can be set for the thick-walled area in the center of the mold and the thin-walled area at the edge to further optimize the curing process.

[0063] Multiple heating components work in parallel, so even if one component fails, the others can continue to work, reducing the risk of equipment downtime and improving production continuity.

[0064] For example, the resistance heating component 210 can be embedded in the mounting groove inside the support component 220, or fixed to the lower surface of the support component 220 by means of bolts, clips, etc., to ensure good thermal contact.

[0065] In some embodiments, the curing oven cavity has an inlet / outlet direction, and all the resistance heating components 210 are spaced apart along the inlet / outlet direction.

[0066] In these embodiments, the curing chamber has an inlet / outlet direction, which is typically aligned with the opening direction of the oven door, i.e., the mold is pushed into or pulled out of the curing chamber through the oven door along the inlet / outlet direction. All resistance heating components 210 are spaced apart along the inlet / outlet direction. For example, two or more heating rods, heating plates, or heating wires are arranged linearly or in an array along the inlet / outlet direction.

[0067] Since the mold moves along the in-and-out direction during loading and unloading, and the heating components are evenly distributed along this direction, it can ensure that the mold is always in a uniform preheating or cooling zone during loading and unloading, reducing temperature fluctuations caused by position changes.

[0068] For long basin-type insulator molds or other long strip products, arranging multiple heating components along the inlet and outlet directions can effectively avoid uneven temperature problems such as cold ends and hot middle or hot front and cold back, and achieve uniform heating along the length of the mold.

[0069] The resistance heating components 210 distributed along the inlet and outlet directions can be divided into multiple heating zones (such as inlet zone, middle zone, and outlet zone), each zone connected to an independent temperature control submodule. In the curing process, different temperature profiles can be set; for example, the inlet zone temperature can be slightly lower to prevent premature surface curing, the middle zone temperature can be high to ensure sufficient reaction, and the outlet zone temperature can be gradually reduced to achieve more precise gradient control.

[0070] In some embodiments, the resistance heating assembly 210 includes at least one heating rod 212 and a heat-conducting block 211, the heat-conducting block 211 and the support assembly 220 are detachably connected, the heat-conducting block 211 has at least one mounting channel 213, and a heating rod 212 is disposed in each mounting channel 213.

[0071] In these embodiments, the resistance heating assembly 210 includes at least one heating rod 212 and a heat-conducting block 211. The heat-conducting block 211 is made of a highly thermally conductive metal material (such as aluminum alloy, copper alloy, or stainless steel), and its shape can be cuboid, cylindrical, or an irregular shape customized according to the contour of the mold bottom surface. The heat-conducting block 211 is detachably connected to the support assembly 220, for example, by bolts, clips, or quick clamps, facilitating disassembly and assembly during maintenance, replacement, or changing to a suitable heat-conducting block 211 for different molds.

[0072] The heat-conducting block 211 has at least one mounting channel 213 inside. The mounting channel 213 is a blind hole or through hole structure, and its diameter matches the outer diameter of the heating rod 212 to ensure that the heating rod 212 is in close contact with the inner wall of the heat-conducting block 211. Each mounting channel 213 is provided with a heating rod 212, which is an electric heating element, such as a stainless steel electric heating rod or a ceramic electric heating rod. When energized, it generates heat and conducts the heat efficiently and evenly to the support assembly 220 and the mold above it through the heat-conducting block 211.

[0073] In one embodiment, a plurality of parallel mounting channels 213 are provided within a single heat-conducting block 211, and a heating rod 212 is installed in each channel 214, forming a heating unit of a heat-conducting block 211 and multiple heating rods 212. Multiple such heating units can be arranged at intervals on the support assembly 220 along the inlet and outlet direction of the curing oven cavity to achieve large-area and highly uniform bottom heating.

[0074] The heat-conducting block 211 serves as an intermediate heat transfer medium. Its high thermal conductivity can quickly diffuse the heat generated by the heating rod 212 to the entire contact surface, avoiding local hot spots and improving heating uniformity.

[0075] Heating rod 212 is usually a consumable part. It adopts a detachable heat-conducting block 211, so that when heating rod 212 is damaged, only heating rod 212 can be removed for replacement or repair without disassembling the entire support assembly 220 or furnace body 110, which greatly improves the maintainability and efficiency of the equipment.

[0076] The wiring terminals of the heating rod 212 extend from the side or end of the heat-conducting block 211 and connect to an independent temperature control module for precise temperature control. The contact surfaces between the heat-conducting block 211 and the support assembly 220 can be polished or coated with thermal grease to further reduce contact thermal resistance. It should be noted that the external cable of the heating rod 212 is a high-temperature resistant insulated cable.

[0077] For example, the heating rod 212 has a base at its end, and the base and mounting hole 213 are threaded together. Alternatively, the base and the heat-conducting block 211 are connected by screws, etc.

[0078] In some embodiments, the heat-conducting block 211 has a plurality of channels 214, which are connected to the curing oven cavity.

[0079] In these embodiments, the heat-conducting block 211 also has a plurality of channels 214, which are connected to the curing oven cavity. These channels 214 are different from the mounting channels 213 used to install the heating rod 212, and are instead ventilation channels 214 or convection channels that penetrate the upper and lower surfaces or sides of the heat-conducting block 211, so that the internal space of the curing oven cavity is connected to the area below the heat-conducting block 211 (or the internal space of the support assembly 220).

[0080] During the heating process, hot air can flow between the upper and lower regions of the heat-conducting block 211 through the channel 214, breaking the thermal shielding effect formed by the heat-conducting block 211 itself, allowing the air in the furnace cavity to circulate and improving the overall temperature uniformity.

[0081] When the temperature in the bottom area is too high, the channel 214 can accelerate the diffusion of heat to the upper part of the furnace cavity, avoid overheating of the surface of the heat-conducting block 211, and help to achieve a gentler temperature gradient.

[0082] While ensuring the structural strength and thermal conductivity of the heat-conducting block 211, setting multiple channels 214 can reduce the amount of material used and lower the weight and cost of the module.

[0083] For example, multiple channels 214 are distributed in a grid or array on the heat-conducting block 211 and are located between adjacent mounting channels 213 or in the outer area of ​​the heating rod 212.

[0084] For example, the channel 214 is a bolt hole on the heat-conducting block 211, and the heat-conducting block 211 is connected to the support assembly 220 by bolts.

[0085] In some embodiments, the support component 220 may be a support base, such as a square tube, channel steel, etc.

[0086] In some embodiments, the furnace body module 100 further includes an anti-collision component 120, which is located inside the curing furnace cavity and disposed on the periphery of the furnace body 110 to prevent the inner wall of the furnace body 110 from being impacted or scratched.

[0087] In these embodiments, the anti-collision component 120 is used to protect the inner wall of the furnace body 110 from impacts, scratches or abrasions that may occur during the loading, unloading or moving of the mold, thereby extending the service life of the furnace body 110 and keeping the interior of the furnace cavity clean and the thermal performance stable.

[0088] The anti-collision component 120 is located inside the curing oven cavity and is installed along the inner wall of the oven body 110. Specifically, the anti-collision component 120 has a semi-circular or segmented strip structure and is fixed to the bottom, middle, or arranged along the entire height of the inner wall of the oven body 110. Its installation method can be welding, screw connection, or snap-fit ​​installation to ensure structural stability.

[0089] For example, the anti-collision component 120 is made of a material with high wear resistance, high temperature resistance and a certain degree of elasticity, such as stainless steel plate, aluminum alloy profile, high temperature resistant engineering plastic, ceramic coated metal plate or silicone rubber covered metal frame, etc.

[0090] The anti-collision assembly 120 should be positioned at a height that covers the area most likely to come into contact with the inner wall of the furnace body 110 during mold handling. For example, in the production of basin insulators, operators often use forklifts or trolleys to deliver the molds into the furnace, and the outer edge of the mold or its support frame is prone to slight collisions with the side wall of the furnace body 110. The anti-collision assembly 120 is located in this risk area, providing effective physical isolation and cushioning.

[0091] For example, the anti-collision component 120 may be a guardrail or the like.

[0092] In some embodiments, this application also provides a casting and curing production equipment, which includes a primary curing oven as described in any of the above embodiments.

[0093] Since the aforementioned primary curing oven has the aforementioned technical effects, the casting and curing production equipment including the primary curing oven should have the same technical effects, which will not be elaborated here.

[0094] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0095] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
