Abstract
Description
Technical Field
[0001] This application relates to the field of hot press technology, and more particularly to a hot press for processing metal nameplates. Background Technology
[0002] Metal signs are made from raw materials such as copper, iron, aluminum, zinc alloy, titanium, and stainless steel, using processes such as stamping, die casting, etching, printing, enamel, imitation enamel, baking paint, epoxy resin coating, and electroplating. Metal hot pressing involves placing heated metal into a prepared mold, then using external hydraulic pressure to force the metal into the mold, thus shaping the metal to match the mold's form. This process is suitable for mass production of metal signs and requires a metal hot press.
[0003] Currently, Chinese utility model patent application CN220387587U, published on January 26, 2024, discloses an automatic hot press machine for spoons. It includes a first wooden board and a base. Fixed posts are fixedly connected to the center of the left and right sides of the top surface of the first wooden board. A second wooden board is fixedly connected to the top surface of the two fixed posts. A hydraulic rod is fixedly connected to the center of the bottom surface of the second wooden board. A hot press plate is fixedly connected to the lower end of the hydraulic rod. A snap-fit groove is formed at the center of the bottom surface of the hot press plate. This utility model achieves quick replacement of the hot press mold and molding groove by using a pin in conjunction with the pin groove and a groove inside the first wooden board, which in turn connects to a first automatic telescopic rod fixedly connected to the bottom center of the groove, and a molding block fixedly connected to the upper end of the first automatic telescopic rod. This allows for the molding of spoons of different specifications to be molded in the same hot press, reducing operating costs and increasing the practicality and applicability of the automatic hot press machine for spoons.
[0004] One type of automatic hot press machine for spoons involves a problem: because metal materials have a certain degree of adhesion after heating, the hot press plate and molding tank need to apply a large pressure to the metal material during the hot pressing operation to shape it. During this process, the hot-pressed metal products may stick to the hot press plate and need to be removed manually, which not only reduces the production efficiency of the hot press machine but also increases the safety risks for operators. Utility Model Content
[0005] This application provides a hot press for processing metal nameplates, which can improve the technical problem in the related art that metal materials may adhere to the hot press plate after hot pressing.
[0006] This application provides a hot press for processing metal nameplates, including: an upper support plate, a lower support plate, legs, optical shafts, and a pressing mechanism. The legs are disposed at the bottom of the lower support plate, and multiple optical shafts are disposed at the top of the lower support plate. One end of each optical shaft is fixedly connected to the lower support plate, and the other end is fixedly connected to the upper support plate. The pressing mechanism includes a first mold, a first hydraulic press, a sliding support plate, and a second mold. The sliding support plate is located between the upper and lower support plates and is slidably connected to the optical shafts. The first hydraulic press is disposed at the top of the upper support plate, and its output end passes through the upper support plate and is fixedly connected to the top of the sliding support plate. The first mold is disposed at the bottom of the sliding support plate, and the second mold is disposed at the top of the lower support plate. A pressing groove is formed at the top of the second mold, and a first sliding groove is formed at the bottom of the first mold. A first slider is slidably connected in the first sliding groove, and a spring is disposed inside the first sliding groove. One end of the spring abuts against the first slider, and the other end of the spring abuts against the top of the first sliding groove.
[0007] The technical solution described above in this application embodiment has at least the following technical effects: After the worker places the heated metal raw material inside the pressure mold groove, the first hot press drives the sliding support plate and the first mold to move downward. When the first mold touches the metal raw material, the first slider is pushed upward by the metal raw material and slides upward inside the first groove. The first mold and the pressure mold groove cooperate to press the metal raw material into a product of a certain shape. Then, the first hydraulic press drives the sliding support plate and the first mold to move upward. The first slider will slide downward inside the first groove under the action of the spring force. If the product adheres to the surface of the first mold at this time, the first slider will apply a downward pushing force to the product to detach the product from the first mold, and there is no need for manual removal of the product, thus improving the working efficiency of the hot press.
[0008] The hot press for processing metal nameplates provided in this application embodiment is equipped with a spring and a first slider on the first mold, which can detach the product adhering to the first mold from the first mold, thereby improving the production efficiency of the equipment.

A second hydraulic press is provided at the bottom of the lower support plate. The output end of the second hydraulic press passes through the lower support plate and is slidably connected inside the second groove. The output end of the second hydraulic press is fixedly connected to the end of the second slider near the second hydraulic press.
[0011] In some embodiments, the second mold includes a molding ring and a molding base, and a connecting ring is provided on the outer peripheral surface of both the molding ring and the molding base. The molding ring and the molding base are connected by connecting ring bolts.
[0012] In some embodiments, a storage basket is fixedly connected to the lower support plate.

[0029] Metal signs are made from raw materials such as copper, iron, aluminum, zinc alloy, titanium, and stainless steel, using processes such as stamping, die casting, etching, printing, enamel, imitation enamel, baking paint, epoxy resin coating, and electroplating. Metal hot pressing involves placing heated metal into a prepared mold, then using external hydraulic pressure to force the metal into the mold, thus shaping the metal to match the mold's form. This process is suitable for mass production of metal signs and requires a metal hot press.
[0030] An automatic hot press machine for spoons, disclosed in CN220387587U, includes a first wooden board and a base. Fixed posts are fixedly connected to the center of the left and right sides of the top surface of the first wooden board. A second wooden board is fixedly connected to the top surface of the two fixed posts. A hydraulic rod is fixedly connected to the center of the bottom surface of the second wooden board. A hot press plate is fixedly connected to the lower end of the hydraulic rod. A snap-fit groove is formed at the center of the bottom surface of the hot press plate. This invention achieves quick replacement of the mold and forming groove of the hot press machine by using a pin in conjunction with the pin groove and a groove inside the first wooden board, which in turn connects to a first automatic telescopic rod fixedly connected to the bottom center of the groove and a shaping block fixedly connected to the upper end of the first automatic telescopic rod. This allows for the shaping of spoons of different specifications in the same hot press, reducing operating costs and increasing the practicality and applicability of the automatic hot press machine for spoons.
[0031] However, since metal materials have a certain degree of adhesion after heating, the hot press plate and molding tank need to apply a large pressure to the metal material to shape it during hot pressing. During this process, the hot-pressed metal products may stick to the hot press plate and need to be removed manually, which not only reduces the production efficiency of the hot press machine but also increases the safety risks for operators.
[0032] Based on this, in order to improve the problems in the related technologies, the embodiments of this application provide the following solutions.
[0033] Please refer to the following: Figures 1 to 4 This application provides a hot press for processing metal nameplates, including an upper support plate 1, a lower support plate 2, a support leg 3, an optical shaft 4, and a pressing mechanism. The pressing mechanism is used to perform hot pressing forming operations on metal raw materials.
[0034] Please refer to the following: Figures 1 to 4 The support leg 3 is located at the bottom of the lower support plate 2. Multiple optical axes 4 are located at the top of the lower support plate 2. One end of each optical axis 4 is fixedly connected to the lower support plate 2, and the other end is fixedly connected to the upper support plate 1. The pressing mechanism includes a first mold 51, a first hydraulic press 53, a sliding support plate 52, and a second mold 54. The sliding support plate 52 is located between the upper support plate 1 and the lower support plate 2 and is slidably connected to the optical axes 4. The first hydraulic press 53 is located at the top of the upper support plate 1, and its output end passes through the upper support plate 1 and is fixedly connected to the top of the sliding support plate 52. The first mold 51 is located at the bottom of the sliding support plate 52. The second mold 54 includes a pressing ring 541 and a pressing base 542. Connecting rings 5411 are provided on the outer circumference of both the pressing ring 541 and the pressing base 542. The pressing ring 541 is located at the top of the pressing base 542 and is bolted to the pressing base 542 via the connecting rings 5411. The base plate 542 is set on the top of the lower support plate 2. The compression ring 541 has a compression groove 543. The bottom of the first mold 51 has a first slide groove 511. The first slide groove 512 is slidably connected in the first slide groove 511. The first slide groove 511 also has a spring 513 inside. One end of the spring 513 abuts against the first slide groove 512, and the other end of the spring 513 abuts against the top of the first slide groove 511. The side of the first slide groove 512 near the spring 513 has a limit post 5121. The limit post 5121 passes through the inside of the spring 513. The compression plate 542 has a second slide groove 5421. The second slide groove 5422 is slidably connected in the second slide groove 5421. The bottom of the lower support plate 2 has a second hydraulic press 6. The output end of the second hydraulic press 6 passes through the lower support plate 2 and is slidably connected in the second slide groove 5421. The output end of the second hydraulic press 6 is fixedly connected to the end of the second slide groove 5422 near the second hydraulic press 6.
[0035] With this configuration, in the initial state, the top of the second slider 5422 is flush with the bottom of the molding groove 543. After the operator places the heated metal material into the molding groove 543, the first hot press drives the sliding support plate 52 and the first mold 51 to move downwards. When the first mold 51 touches the metal material, the first slider 512 and the limiting post 5121 slide upwards inside the first slide groove 511 under the pushing force of the metal material. When the top of the limiting post 5121 contacts the top of the first slide groove 511, the bottom of the first slider 512 is exactly flush with the bottom of the first mold 51. This prevents the bottom of the first slider 512 from moving above the bottom of the first mold 51 under the pushing force of the metal material, thus avoiding bulging on the product surface. After the first mold 51 and the pressing groove 543 press the metal material into a certain shape, the first hydraulic press 53 drives the sliding support plate 52 and the first mold 51 to move upward. The first slider 512 will slide downward inside the first groove 511 under the elastic force of the spring 513. If the product adheres to the surface of the first mold 51 at this time, the first slider 512 will apply a downward pushing force to the product to keep it from the first mold 51. The first mold detaches the product, eliminating the need for manual removal and improving the efficiency of the hot press. Simultaneously, the second hydraulic press 6 drives the second slider 5422 to slide upwards within the second groove 5421. If the product adheres to the top of the mold base 542 after the first mold 51 is raised, the second slider 5422 applies an upward pushing force to detach it from the mold base 542, facilitating subsequent removal of the product from the mold groove 543. Then, the second hydraulic press 6 drives the second slider 5422 to slide downwards back to its initial position within the second groove 5421. Prepare for the next hot pressing operation; since an oxide layer will form on the surface of the metal raw material after heating, during the hot pressing operation, the oxide layer on the metal surface will fall off the surface of the metal raw material into the pressing mold groove 543 due to its poor ductility. After long-term use of the hot press, a lot of oxide layer will accumulate inside the pressing mold groove 543, which will affect the normal operation of the hot pressing operation. At this time, the operator can remove the bolts connecting each connecting ring 5411 to remove the pressing mold ring 541 from the top of the pressing mold base 542 and clean the oxide layer accumulated on the top of the pressing mold base 542, thereby ensuring the normal operation of the hot press.
[0036] Optionally, in some embodiments, please also refer to Figures 1 to 4 A storage basket 21 is fixedly connected to the lower support plate 2. A ventilation opening 212 is provided on one side of the storage basket 21. Multiple ventilation holes 211 are provided on the surface of the storage basket 21. A cooling fan 71 is provided at the bottom of the lower support plate 2. A cooling hood 72 is fixedly connected to the air outlet of the cooling fan 71. The air inlet of the cooling hood 72 is connected to the air outlet of the cooling fan 71. The end of the cooling hood 72 away from the cooling fan 71 is fixedly connected to the storage basket 21 through the ventilation opening 212.
[0037] With this setup, after the hot pressing operation is completed, the staff can clamp the product from inside the molding groove 543 and place it in the storage basket 21 for temporary storage to allow it to cool naturally. The cooling fan 71 can blow cold air through the cooling hood 72 to the surface of the product placed inside the storage basket 21 to cool it quickly. The ventilation hole 211 can accelerate the flow of gas between the inside and outside of the storage basket 21, thereby accelerating the cooling of the product. Then, the staff can take the cooled product out of the storage basket 21 for subsequent work, avoiding the product from accumulating in the storage basket 21 for a long time and affecting the production efficiency of the hot press.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
