Description

Technical Field

[0001] The utility model relates to the technical field of metal stamping dies, in particular to a cooling mechanism for metal stamping dies. Background Technique

[0002] During the processing of metal stamping dies, due to continuous use, the dies absorb heat when contacting high-temperature metals during stamping, resulting in an increase in the die temperature. This requires cooling to ensure the service life and processing quality of the dies. The chiller plays an important role in the cooling process of metal stamping dies. Its basic principle is to use the circulating cooling medium - ice water to take away the heat generated by the dies during processing, thereby achieving the cooling effect. During the whole process, the cooling water, as the medium to be cooled, exchanges heat with the refrigerant through the evaporator (evaporation coil) in the water tank at the top of the chiller, thereby reducing the temperature. The material of some coil-type evaporators usually uses copper-core coils, and this material has a high heat transfer coefficient; the dust and impurities accumulated on the surface of the copper-core coils may affect the heat dissipation performance and insulation performance, and should be regularly cleaned to keep clean. The existing cleaning method is to wipe it manually with a soft cleaning cloth. However, the space between the evaporation coil and the inner wall of the water tank is relatively narrow, and it is difficult for the hand to reach in, so some corners of the evaporation coil are difficult to clean. Moreover, there is often residual water inside the water tank, so when the equipment is not in use, the inside of the water tank is often in a humid state, accelerating the aging of the evaporation coil and making it inconvenient to use.

Detailed Description of the Preferred Embodiment

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1 to 6, in the embodiment of the present utility model, a cooling mechanism for a metal stamping die includes a chiller body 10. An inner water storage tank 101 and an installation groove 102 are formed inside the chiller body 10. A temperature sensor 103, a drain port 104 and an evaporation coil body 105 are fixedly arranged on the inner bottom surface of the water storage tank 101; a limiting rod 11 is slidably arranged inside the water storage tank 101, a connecting rod 111 is slidably connected to the outer wall of the limiting rod 11, one end of the connecting rod 111 is rotatably connected with a snap ring 112, and the evaporation coil body 105 passes through the snap ring 112; a driving module 12 is arranged inside the installation groove 102 for driving the limiting rod 11; an auxiliary module 14 is arranged outside the chiller body 10 for assisting in air-drying the water storage tank 101.

[0033] Specifically, by rotatably connecting a snap ring 112 to one end of the connecting rod 111 and starting the first motor 124 to drive the connecting rod 111 to rotate, the snap ring 112 can gradually lift along the outer wall of the evaporation coil body 105 to scrape and clean the outer wall of the evaporation coil body 105, facilitating automatic dust removal from the outer wall of the evaporation coil body 105, saving manpower. Rotate the limiting shell 146 to the top of the water storage tank 101 and start the air pump 148 to blow hot air into the water storage tank 101, which can accelerate the air-drying and dehumidification of the evaporation coil body 105 and the inside of the water storage tank 101, facilitating the reduction of water residue inside the water storage tank 101 and extending the service life of the evaporation coil body 105, making it convenient to use.

[0034] Embodiment 1

[0035] As Figure 1-5 shown, in this embodiment, the driving module 12 includes: a sleeve 121 fixedly connected to the inner bottom surface of the installation groove 102; a limiting plate 122 is slidably connected between the inner walls of the water storage tank 101, a shaft block 123 is rotatably connected inside the limiting plate 122, and the top end of the shaft block 123 is fixedly connected to the limiting rod 11; a first motor 124 is fixedly connected to the bottom of the limiting plate 122, the output end of the first motor 124 penetrates through the limiting plate 122 and is fixedly connected to the shaft block 123, a second motor 126 is fixedly connected to the top of the limiting plate 122, a gear 127 is fixedly sleeved on the output end of the second motor 126, and a rack 125 is fixedly connected to the inner bottom surface of the installation groove 102, and the gear 127 meshes with the rack 125.

[0036] In this embodiment, through the limitation of the limiting plate 122 by the sleeve 121, the sliding limitation of the limiting rod 11 in the vertical direction is realized, and through the limitation of the shaft block 123 by the limiting plate 122, the rotational limitation of the limiting rod 11 is realized. Starting the first motor 124 can drive the limiting rod 11 to rotate. The limiting rod 11 drives the clamping ring 112 to move along the outer wall of the evaporation coil body 105 through the connecting rod 111. The rotational connection between the clamping ring 112 and the connecting rod 111 enables the clamping ring 112 to automatically adjust the angle. And as the clamping ring 112 rises, the clamping ring 112 drives the connecting rod 111 to slide upward on the outer wall of the limiting rod 11. Starting the second motor 126 drives the gear 127 to rotate, and through the transmission of the gear 127 and the rack 125, the limiting plate 122 is driven to move upward, thereby driving the entire limiting rod 11 to move upward to the topmost position, improving the lift range of the connecting rod 111.

[0037] As Figure 3-5 shown, in this embodiment, a cleaning ring 1121 is fixedly connected to the inner wall of the clamping ring 112. A clamping plate 113 is rotatably connected to the inner bottom surface of the water storage tank 101. The limiting rod 11 passes through the clamping plate 113 and is slidably connected to it. A sealing ring 13 is fixedly embedded at the top of the clamping plate 113.

[0038] During specific implementation, the cleaning ring 1121 is made of sponge and has a certain elasticity, enabling it to fit more closely to the outer wall of the evaporation coil body 105. Through the scraping of the cleaning ring 1121, the outer wall of the evaporation coil body 105 can be cleaned, and the dust can be scraped off. The clamping plate 113 can rotate synchronously with the limiting rod 11, and the sealing ring 13 also rotates simultaneously, thereby realizing the stable sealing of the sliding part of the limiting rod 11.

[0039] Embodiment Two

[0040] On the basis of Embodiment One, in order to accelerate the air drying of the evaporation coil body 105 and at the same time reduce the residual moisture inside the water storage tank 101.

[0041] As Figure 2-6 shown, in this embodiment, the auxiliary module 14 includes: a first support arm 141, and a second support arm 142 is rotatably connected to the top end of the first support arm 141 through a hinge; a limiting shell 146 is fixedly connected to one end of the second support arm 142, and a plurality of air outlets 1461 are equidistantly arranged at the bottom of the limiting shell 146; a heating wire 147 is fixedly connected to the inner wall of the limiting shell 146; an air pump 148 is fixedly connected to the top of the limiting shell 146, and the air outlet end of the air pump 148 passes through the limiting shell 146 and extends into its interior. A docking plate 143 is fixedly connected to the top of the second support arm 142. Two limiting sleeves 144 are fixedly connected to the outer wall of the chiller body 10. The first support arm 141 passes through the two limiting sleeves 144 and is slidably connected to them. A support plate 145 for limiting the first support arm 141 is fixedly connected to the outer wall of the chiller body 10.

[0042] During specific implementation, supplying power to the heating wire 147 can increase the temperature inside the limiting shell 146. After starting the air pump 148 to blow air and heat inside the limiting shell 146, the hot air is ejected from the air outlet 1461. When the limiting shell 146 is in a horizontal state, the second support arm 142 supports the limiting shell 146. The hot air is blown into the inside of the water storage tank 101 and continuously gushes out, thereby accelerating the air drying of the evaporation coil body 105. The two limiting sleeves 144 cooperate to slide and limit the first support arm 141. When the limiting shell 146 is not in use, first rotate the second support arm 142 to a vertical state, and then move the first support arm 141 and the second support arm 142 downward as a whole until the support plate 145 contacts the bottom end of the first support arm 141 for support. Under the limitation of the docking plate 143, the first support arm 141 and the second support arm 142 can no longer rotate, but remain in a parallel state and are stored on the outer wall of the chiller body 10.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
