Description

Technical Field

[0001] The invention belongs to the technical field of mold processing, and in particular relates to a mold surface treatment device for preventing high temperature oxidation. Background Art

[0002] In the mold manufacturing industry, mold surface treatment is a crucial link, which is directly related to the mold's service life, wear resistance, corrosion resistance and high temperature oxidation resistance. Traditional mold surface anti-high temperature oxidation treatment methods include polishing, and after polishing, the mold surface usually needs to be further plated with an anti-oxidation coating to improve its high temperature oxidation resistance. Anti-oxidation coating is a two-step process.

[0003] Both chemical polishing and chemical plating involve placing the mold in a specific chemical solvent to achieve the purpose of surface treatment through chemical reactions. However, many steps of chemical polishing and chemical plating require manual operation, which is not only labor-intensive but also easily affected by human factors, thus affecting the quality of the coating. At the same time, the chemicals used in the chemical polishing and chemical plating process are often highly corrosive and toxic. If the operation is improper or protective measures are not in place, it is easy to cause chemical burns, poisoning and other hazards to the operator. In addition, since the proportion and reaction time of various chemical agents need to be strictly controlled during chemical polishing and chemical plating, traditional operating methods often rely on manual experience and judgment, and it is difficult to accurately control the polishing time, thus affecting the polishing and coating effects.

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-8As shown, a mold anti-high temperature oxidation surface treatment device includes an annular slide rail 1, a slide rail trolley 2 slidably connected to the annular slide rail 1 is installed on the upper side of the annular slide rail 1, a plurality of fixing rods 3 are fixed on the top of the annular slide rail 1, a base 111 is fixed on the lower side of the slide rail trolley 2, a reduction motor 4 is installed on the upper side of the base 111, a driving wheel 5 abutting the annular slide rail 1 is concentrically fixed to the output end of the reduction motor 4, a cantilever 6 hinged to the left and right is suspended on the lower side of the base 111, a hanging plate 7 is fixed on the lower side of the cantilever 6, a fixing hole 8 is opened on the upper side of the hanging plate 7, a hook 9 matching the fixing hole 8 is installed on the upper side of the hanging plate 7, a plurality of U-shaped slide rails 10 distributed at intervals on the left and right and matching the annular slide rail 1 are arranged on the front and rear sides of the annular slide rail 1, and a solution tank 11 is arranged on the lower side of the U-shaped slide rail 10.

[0027] The solution tank 11 on the front side is filled with different solutions required for chemical polishing of the mold surface, and the solution tank 11 on the rear side is filled with different solutions required for chemical plating. The fixing rod 3 is fixedly installed on the lower side of the ceiling. The annular slide rail 1 provides a stable motion track for the entire device. The slide trolley 2 is slidably connected to the annular slide rail 1, and can move smoothly along the track. The reduction motor 4 drives the driving wheel 5 to rotate through the output end, thereby driving the entire device to move along the annular slide rail 1. When the present invention is in use, the mold to be processed is suspended to the lower side of the cantilever 6 by the hook 9. The U-shaped slide rail 10 matching the annular slide rail 1 enables the slide trolley 2 and the mold as a whole to move downward when passing over the solution tank 11, and the mold can be immersed in the solution for processing during the movement.

[0028] The annular slide rail 1, the U-shaped slide rail 10, the slide rail trolley 2 and the cantilever 6 machine hook 9 on the lower side enable the mold to automatically enter and leave the solution and transfer between different solution tanks 11 under the drive of the slide rail trolley 2, avoiding direct contact between the operator and the solution, thereby reducing the possible harm to the human body caused by the chemical solution and greatly reducing the physical burden of the operator. At the same time, the automated processing process can accurately control the immersion and removal time of the mold, reducing errors caused by human factors, thereby improving the accuracy and consistency of the processing results, and improving production efficiency and mold processing quality.

[0029] The lower side of the base 111 is also provided with an anti-swing component, which includes a rotating rod 12 rotatably connected to the base 111 and fixedly connected to the cantilever 6, a disc 13 fixed concentrically therewith is rotatably installed on the rear side of the rotating rod 12, and a plurality of evenly distributed circumferential blocks 14 are installed on the rear side of the disc 13, a sliding sleeve 15 distributed left and right is fixed on the lower side of the base 111, a sliding rod 16 is slidably installed inside the sliding sleeve 15, a limited block 17 is fixed on the rear side of the sliding rod 16, a limited groove 18 matching the block 14 is opened on the front side of the limited block 17, and a horizontal fixed block 16 is fixed on the front side of the sliding rod 16. Plate 19, a top wheel 20 that rotates horizontally left and right is installed in the middle of the cross plate 19, a reset spring 21 is sleeved on the outer side of the slide rod 16, and the front and rear ends of the reset spring 21 are respectively fixedly connected to the slide sleeve 15 and the cross plate 19, a top plate group is installed on the front side of the annular slide rail 1 and the rear side of the annular slide rail 1, and a fixing rod 3 is also fixedly connected to the middle of the top plate group, and the top plate group matches the U-shaped slide rail 10 and the top wheel 20, each top plate group includes S-shaped top plates 22 that are symmetrically distributed at left and right intervals, and the left and right ends of the S-shaped top plates 22 are provided with inclined surfaces 23 close to the side of the annular slide rail 1.

[0030] The top plate groups are fixedly connected to the ceiling through the fixing rods 3, and when the slide rail trolley 2 moves forward to the U-shaped slide rail 10, the S-shaped top plates 22 spaced apart on the left and right and the inclined surfaces 23 on both sides can enable the top wheel 20 to drive the slide bar 16 and the limit block 17 to move backward. At this time, the limit groove 18 is separated from the block 14, and the cantilever 6 can rotate freely. When the slide rail trolley 2 moves horizontally at the bottom of the annular slide rail 1 and the U-shaped slide rail 10, the top wheel 20 leaves the S-shaped top block. At this time, the reset spring 21 makes the disc 13 fit with the limit block 17, and the block 14 and the limit groove 18 now rotate the cantilever 6.

[0031] The cooperation of the slide bar 16, the top wheel 20, the top plate group, the block 14 and the slot enables the cantilever 6 to rotate freely and be perpendicular to the ground when the slide trolley 2 moves to the U-shaped slide rail 10, and the cooperation of the reset spring 21 and the cross plate 19 enables the anti-swing component to maintain the groove contact with the limit block 17 when not subject to external force, so that the block 14 is inserted into the inner side of the limit groove 18, thereby preventing the cantilever 6 from shaking left and right when the slide trolley 2 moves or stops, ensuring the safety of the processing process, and at the same time making it convenient for the cantilever 6 to be more stable when the hook 9 is installed, thereby improving the convenience of equipment use.

[0032] A limiting clamping plate 24 fixedly connected to the hanging plate 7 is installed on the lower side of the fixing hole 8, and a limiting clamping block 25 matching the limiting clamping plate 24 is fixed on the upper side of the hook.

[0033] When the hook is hung to the inner side of the fixing hole 8, the limiting block 25 is inserted into the inner side of the limiting plate 24, and the hook cannot swing left and right at this time, thereby further improving the stability of the mold during driving.

[0034] The hanging plate 7 is oriented left and right, and there are multiple fixing holes 8 on the upper side of the hanging plate 7 that are evenly distributed left and right. There are multiple limiting clamping plates 24 on the lower side of the hanging plate 7 that correspond one-to-one to the multiple fixing holes 8 .

[0035] The provision of multiple uniform fixing holes 8 on the upper side of the hanging plate 7 increases the fixing position of the hook 9, and also enables the multiple hooks 9 and the molds suspended below to flexibly adjust the fixing positions, so that the cantilever 6 is more balanced in the vertical force, which increases the flexibility of the installation of the hook 9 and the mold while increasing the equipment's processing efficiency of the mold.

[0036] The reduction motor 4 is hinged to the base 111 up and down, and the driving wheel 5 is rotatably connected to a fixed block 26 away from the reduction motor 4. The lower side of the fixed block 26 is connected to a tensioning spring 27 fixed to the base 111. Rubber pads 28 are fixed to the bottom of the annular slide rail 1 and the U-shaped slide rail 10, and the driving wheel 5 abuts against the rubber pad 28.

[0037] The hinged connection between the reduction motor 4 and the base 111 enables the driving wheel 5 to always be in contact with the annular slide rail 1 and the U-shaped slide rail 10. The use of the rubber pad 28 further increases the friction between the driving wheel 5 and the annular slide rail 1 and the U-shaped slide rail 10, thereby improving the operating stability of the equipment and making the movement of the slide trolley 2 more precise, further ensuring the processing quality of the mold.

[0038] A conductive slip ring 29 matching the circular slide rail 1 and fixed to the upper fixing rod 3 is horizontally installed on the upper side of the circular slide rail 1, a contact fork 30 matching the conductive slip ring 29 is installed on the upper side of the base 111, a spring sheet 31 abutting against the conductive slip ring 29 is installed on the inner side of the contact fork 30, and a battery 32 is installed on the inner side of the base 111, and the battery 32 is electrically connected to the spring sheet 31 and the reduction motor 4 respectively.

[0039] The conductive slip ring 29 is connected to an external power source, and the contact fork 30 abuts against the conductive slip ring 29 , and a stable electrical connection is maintained through the spring sheet 31 to charge the battery 32 , and the battery 32 provides power support for the reduction motor 4 .

[0040] The reduction motor 4 of the slide rail trolley 2 uses a battery 32 to provide power for it. The conductive slip ring 29 and the spring sheet 31 are used to charge the battery 32 when the slide rail trolley 2 moves on the upper side of the annular slide rail 1. This design does not require traditional components such as flying wires, and the structure is simpler. This not only improves the reliability and stability of the equipment, but also makes maintenance and replacement more convenient and easy.

[0041] Two washing and blowing assemblies 42 are installed on the lower right side and the lower rear side of the annular slide rail 1. The washing and blowing assembly 42 includes a receiving groove 33, and baffles 34 are vertically installed on the left and right sides of the receiving groove 33. A plurality of evenly distributed water spray heads 35 are installed on the left and right inner sides of the baffles 34. An electric control valve 36 connected to the pipeline of the water spray head 35 is installed on the side of the base 111. A plurality of jet heads 37 are installed on the rear side of the plurality of water spray heads 35 as a whole. The jet heads 37 are evenly distributed on the left and right inner sides of the baffles 34. An air compressor 38 connected to the pipeline of the jet head 37 is installed on the side of the receiving groove 33.

[0042] The electric control valve 36 is connected to an external water source. The evenly distributed water spray heads 35 can rinse the equipment after chemical polishing and chemical plating to prevent residues on the mold surface and improve the safety of the mold. The air compressor 38 cooperates with the evenly distributed air spray heads 37 to spray high-speed gas after the mold is cleaned to dry the moisture on the mold surface, which helps to improve the cleanliness and dryness of the mold and lay a good foundation for subsequent processing and use.

[0043] Two infrared emitting heads 39 are installed at intervals on the front and rear sides of one of the baffles 34 of the washing and blowing assembly 42, and two infrared receiving boards 40 corresponding to the infrared emitting heads 39 are installed at intervals on the left and right sides of the other baffle 34. One of the infrared receiving boards 40 is electrically connected to the electric control valve 36, and the other infrared receiving board 40 is electrically connected to the air compressor 38. A shading plate 41 matching the infrared emitting heads and the infrared receiving board 40 is horizontally fixed on the lower side of the cantilever 6.

[0044] When the equipment is in use, the infrared transmitter 39 transmits an infrared signal which is received by the infrared receiver board 40. At this time, the electric control valve 36 and the air compressor 38 are in a closed state. When the mold and the cantilever 6 pass through the washing and blowing assembly 42, the shading plate 41 on the upper side thereof will block the infrared transmitter and receiver board from receiving the signal. At this time, the infrared receiver board 40 controls the electric control valve 36 to open or the air compressor 38 to work, thereby performing flushing and drying operations.

[0045] The cooperation of the infrared transmitter head 39, the infrared receiving plate 40 and the shading plate 41 enables the washing and blowing assembly 42 to be automatically controlled according to the position of the mold, reducing the reliance on manual operation and reducing labor costs. At the same time, since the flushing and drying process is more precise and efficient, the overall efficiency and stability of the production line are further improved.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
