Description

Technical Field

[0001] This utility model relates to the field of mold heat treatment technology, and specifically to a heat treatment device for mold processing. Background Technology

[0002] Molds are typically made from a variety of different materials, such as mold steel and alloy steel. Heat treatment can alter the internal structure of the mold material, eliminate residual stress, and improve its toughness, thereby increasing the mold's hardness and wear resistance. This is especially important for injection molds, as they must withstand the pressure and friction of molten plastic during use and possess sufficient hardness and wear resistance to maintain a long service life.

[0003] In existing molds, operators need to put their hands directly into the high-temperature heat treatment chamber during heat treatment to complete the mold material handling operations.

[0004] For example, the patented heat treatment furnace for processing stamping dies disclosed in patent CN220376738U has a fixed placement platform, which means that operators need to put their hands into the high-temperature heat treatment furnace when picking up and putting in materials. Since the heat treatment furnace body has just completed the heat treatment process, its internal temperature is extremely high. This way of working can easily cause burns to the operator's hands and even other parts of the body, seriously threatening the operator's personal safety and health.

[0005] Therefore, it is necessary to invent a heat treatment device for mold processing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a heat treatment device for mold processing, which solves the problem that operators need to directly put their hands into the heat treatment chamber at high temperature to complete the mold material handling operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for mold processing, comprising a heat treatment chamber, a support platform provided on the front side of the heat treatment chamber, two linear slide rails horizontally installed on the bottom surface of the heat treatment chamber and the top surface of the support platform, a platform provided above the linear slide rails, a slide table provided at the bottom of the platform, a through hole provided at the bottom of the heat treatment chamber, an air supply hood provided directly below the through hole, a hot air blower provided on one side of the heat treatment chamber, and an air supply pipe connected to the air outlet of the hot air blower and the air inlet of the air supply hood.

[0008] Preferably, a No. 1 electric heating plate is provided on one side of the inner wall of the heat treatment chamber, a No. 2 electric heating plate is provided on the other side of the inner wall of the heat treatment chamber, a No. 3 electric heating plate is provided on the rear wall inside the heat treatment chamber, a No. 4 electric heating plate is provided on the front wall inside the heat treatment chamber, and a No. 5 electric heating plate is provided on the top surface inside the heat treatment chamber. This all-round layout can heat the mold placed on the platform from multiple angles.

[0009] Preferably, the No. 1, No. 2, No. 3, No. 4 and No. 5 electric heating plates are all fixed by multiple bolts, and all of them are ceramic heating plates. Ceramic materials have good high temperature resistance and electrothermal conversion efficiency, can work stably in high temperature environments, quickly convert electrical energy into heat energy, and have a long service life.

[0010] Preferably, the front side of the platform is provided with a cover plate that matches the opening end of the heat treatment chamber. The inner side of the cover plate is provided with a high-temperature resistant sealing strip to form a tight fit with the opening end of the heat treatment chamber. When the platform enters the heat treatment chamber, the cover plate can cover the opening end, reducing the heat exchange between the inside of the heat treatment chamber and the external environment and reducing heat loss.

[0011] Preferably, the linear slide rail is a ball bearing linear guide rail, and the bottom of the slide table is provided with a slider structure that matches the ball bearing linear guide rail. The ball bearing linear guide rail and the slider structure have high matching accuracy, which can ensure the positional accuracy of the platform during the sliding process, so that the mold can be accurately placed in the designated position inside the heat treatment chamber.

[0012] Preferably, the center of the platform is provided with a hollow platform, which is made of multiple metal rods welded together. When the platform slides into the heat treatment chamber, the hollow platform is precisely aligned with the through hole at the bottom of the heat treatment chamber. This design allows the hot air delivered by the hot air blower to be evenly applied to the bottom surface of the mold through the hollow part of the hollow platform.

[0013] Preferably, the air supply hood is trumpet-shaped with the larger opening facing upwards. This shape design can expand the diffusion range of the hot air delivered by the hot air blower, so that the hot air can be more evenly distributed inside the heat treatment chamber and cover a larger area.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model achieves smooth sliding transfer of molds between the outside and inside of the heat treatment chamber by setting a support platform on the outside of the heat treatment chamber and installing linear slide rails on the bottom surface of the heat treatment chamber and the top surface of the support platform, in conjunction with the placement platform and the slide table at its bottom. The operator only needs to place the mold on the placement platform outside the heat treatment chamber, and then push the placement platform to enter the heat treatment chamber along the linear slide rail for heat treatment. After the heat treatment is completed, the placement platform can be pulled out. The mold loading and unloading operation can be easily completed in a relatively safe external environment without direct contact with the high temperature inside the heat treatment chamber, which greatly improves the safety and convenience of operation.

[0016] 2. This utility model has electric heating plates installed on different directions (right side, left side, rear wall, front wall, and top surface) on the inner wall of the heat treatment chamber, and a hot air blower hood installed at the bottom. This all-round layout can heat the mold placed on the platform from multiple angles, ensuring that the mold is heated evenly during the heat treatment process, avoiding local overheating or insufficient heating, and improving the quality and effect of heat treatment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6 The heat treatment device for mold processing shown includes a heat treatment chamber 1. A support platform 7 is provided on the front side of the heat treatment chamber 1. Two linear slide rails 10 are horizontally installed on the bottom surface of the heat treatment chamber 1 and the top surface of the support platform 7. A platform 8 is provided above the linear slide rails 10. A slide table 11 is provided at the bottom of the platform 8. A through hole 13 is opened at the bottom of the heat treatment chamber 1. A cover plate 9 matching the opening end of the heat treatment chamber 1 is provided on the front side of the platform 8. A high-temperature resistant sealing strip is provided on the inner side of the cover plate 9 to form a tight fit with the opening end of the heat treatment chamber 1. The linear slide rail 10 is a ball linear guide rail, and the bottom of the slide table 11 is provided with a slider structure matching the ball linear guide rail.

[0027] In this embodiment, the linear slide rail 10 and the slider structure at the bottom of the slide table 11 have high matching precision, which can ensure the positional accuracy of the platform 8 during the sliding process, so that the mold can be accurately placed in the designated position inside the heat treatment chamber 1. At the same time, it ensures that the sliding process is smooth and stable, without any jamming or shaking, thus ensuring the accuracy and stability of the operation. It also facilitates the mold loading and unloading operations and avoids the risk of burns when operators need to put their hands into the heat treatment chamber 1.

[0028] One electric heating plate 2 is installed on one side of the inner wall of the heat treatment chamber 1, and another electric heating plate 3 is installed on the other side of the inner wall of the heat treatment chamber 1. A third electric heating plate 4 is installed on the rear wall inside the heat treatment chamber 1, a fourth electric heating plate 5 is installed on the front wall inside the heat treatment chamber 1, and a fifth electric heating plate 6 is installed on the top surface inside the heat treatment chamber 1. All electric heating plates 2, 3, 4, 5, and 6 are fixed by multiple bolts and are made of ceramic.

[0029] In this embodiment, the No. 1 electric heating plate 2, No. 2 electric heating plate 3, No. 3 electric heating plate 4, No. 4 electric heating plate 5 and No. 5 electric heating plate 6 are arranged in different directions on the inner wall of the heat treatment chamber 1. They can heat the mold from multiple angles, avoid the problem of local overheating or insufficient heating of the mold, ensure that the mold is heated evenly during the heat treatment process, and improve the quality and effect of heat treatment.

[0030] A hollow platform 12 is provided in the middle of the storage platform 8. The hollow platform 12 is made of multiple metal rods welded together. When the storage platform 8 slides into the heat treatment chamber 1, the hollow platform 12 is precisely aligned with the through hole 13 at the bottom of the heat treatment chamber 1. An air supply hood 14 is provided directly below the through hole 13. A hot air blower 15 is provided on the outer side of the heat treatment chamber 1. An air supply pipe 16 is connected between the air outlet of the hot air blower 15 and the air inlet of the air supply hood 14. The air supply hood 14 is trumpet-shaped with the larger opening facing upward.

[0031] In this embodiment, the hollow platform 12 is precisely aligned with the bottom through hole 13 of the heat treatment chamber 1, and the design of the horn-shaped air hood 14 with its large opening facing upwards allows the hot air delivered by the hot air blower 15 to be evenly distributed inside the heat treatment chamber 1 and to act evenly on the bottom surface of the mold, promoting the circulation of hot air around the mold and further improving the uniformity and efficiency of the heat treatment. Together with the No. 1 electric heating plate 2, No. 2 electric heating plate 3, No. 3 electric heating plate 4, No. 4 electric heating plate 5 and No. 5 electric heating plate 6, it accelerates the heating rate of the mold and the heat treatment process.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-6 When using this utility model, firstly, the operator pulls the platform 8 out onto the support 7 outside the heat treatment chamber 1. At this time, the slide 11 at the bottom of the platform 8 slides smoothly along the linear slide rail 10. Then, the mold that needs to be heat treated is placed on the hollow platform 12 in the middle of the platform 8. Then, the operator slowly and smoothly pushes the platform 8. The slide 11 at the bottom of the platform 8 slides into the heat treatment chamber 1 along the linear slide rail 10. When the platform 8 is completely slid into the heat treatment chamber 1, the cover plate 9 on the front side of the platform 8 is in close contact with the opening end of the heat treatment chamber 1. The high-temperature resistant sealing strip on the inner side of the cover plate 9 is compressed to form a reliable seal.

[0034] Then, the No. 1 electric heating plate 2, the No. 2 electric heating plate 3, the No. 3 electric heating plate 4, the No. 4 electric heating plate 5 and the No. 5 electric heating plate 6 are turned on in sequence. At the same time, the hot air blower 15 is started. The hot air generated by the hot air blower 15 is delivered to the air blower hood 14 through the air supply pipe 16. The hot air can be evenly diffused into the interior of the heat treatment chamber 1. At this time, the hot air is evenly applied to the bottom surface of the mold through the hollow part of the hollow platform 12, thereby realizing the heat treatment of the mold.

[0035] Once the required heat treatment time has been reached, heating and air supply are stopped, allowing the mold to cool naturally inside the heat treatment chamber 1 for a period of time. At this time, the operator pulls the platform 8, and the slide 11 pulls the platform 8 out of the heat treatment chamber 1 along the linear slide rail 10 to the outer support platform 7. The operator can then remove the heat-treated mold from the hollowed-out support platform 12 of the platform 8.
