Description

Technical Field

[0001] This utility model belongs to the field of mold steel technology, and in particular relates to a coating spraying device for heat treatment of mold steel surface. Background Technology

[0002] Mold steel is a specialized steel used in the manufacture of molds. Its main purpose is to withstand high pressure, high temperature, and friction during the production process, and it possesses excellent wear resistance, heat resistance, strength, and toughness. Mold steel is commonly used to produce various types of molds, such as injection molds, die-casting molds, cold stamping molds, and hot forging molds.

[0003] According to the public announcement (Announcement No.: CN213377350U), a spraying device for metal surface composite coating spraying includes a spraying device. The outer left side wall of the spraying device has a movable hole that extends through the inner left side wall of the spraying device and into its interior. A fixing block is fixedly installed at the top of the interior of the spraying device. The cross-sectional area of ​​the fixing block is adapted to the cross-sectional area of ​​the hollow area inside the spraying device. A rotating hole is opened on the top wall of the fixing block that extends through the bottom wall of the fixing block and into the interior of the spraying device. In this utility model, when the stirring blade rotates, the spraying device for metal surface composite coating spraying agitates the liquid inside the spraying device, ensuring uniform mixing. This avoids the situation where, when manually shaking and mixing layered liquids, the liquids cannot be completely mixed together in a short time, resulting in substandard spray quality.

[0004] The aforementioned patent achieves uniform liquid mixing within the spraying device through the cooperation of components such as movable holes, fixed blocks, and agitating spraying devices. However, it cannot achieve a better effect of evenly spreading the coating on the steel surface. Therefore, we propose a coating spraying device for heat treatment of mold steel surfaces. Utility Model Content

[0005] The purpose of this invention is to provide a coating spraying device for heat treatment of mold steel surfaces. The device consists of components such as a motor, threaded rod, threaded sleeve, and limiting rod that work together to solve the problem of uneven coating on steel.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a coating spraying device for heat treatment of mold steel surface, including a base, a connecting frame fixedly connected to the top of the base, a spraying device provided on the top of the connecting frame, an adjustment device provided on the side of the spraying device, a spray nozzle fixedly connected to the bottom of the spraying device, a placement groove provided on the top of the base, and a spreading device provided on the top of the base.

[0008] The spreading device includes a fixed plate, the bottom of which is fixedly connected to the top of a base. A motor is fixedly connected to the side of the fixed plate, and a threaded rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threaded onto the circumferential surface of the threaded rod, and a fixed rod is fixedly connected to the circumferential surface of the threaded sleeve. A compression spring is fixedly connected to the bottom of the fixed rod, and a fixed seat is fixedly connected to one end of the compression spring. An arc-shaped scraper is fixedly connected to the bottom of the fixed seat, and a limit rod is fixedly connected to the side of the fixed plate. This device, mainly driven by a motor and a threaded rod system, enables the coating to be evenly applied to the surface of the mold steel, resulting in a more uniform coating and improved consistency of the mold steel.

[0009] Furthermore, the circumferential surface of the threaded sleeve is slidably connected to the circumferential surface of the limiting rod, and multiple compression springs are provided. The sliding connection design allows the threaded sleeve and the limiting rod to move relative to each other, while the compression springs adjust the positional accuracy during this movement, preventing the sliding parts from moving excessively or becoming misaligned.

[0010] Furthermore, multiple compression springs are arranged linearly along the bottom of the fixed rod, and the initial state of the compression springs is a relaxed state. The initial design of the relaxed state means that the compression springs do not need to bear excessive initial compression pressure, avoiding fatigue from being under high pressure for a long time, thereby extending the service life of the springs.

[0011] Furthermore, the top of the placement groove is located on the displacement trajectory of the arc-shaped scraper. This design, placing the placement groove on the displacement trajectory of the arc-shaped scraper, is primarily to ensure that the arc-shaped scraper always moves along the correct trajectory during operation, thereby improving the stability, accuracy, and durability of the equipment.

[0012] Furthermore, an anti-clogging device is provided on the top of the base. This device includes a toothed rod, the bottom of which is slidably connected to the top of the base. A gear is fixedly connected to the circumferential surface of the threaded rod, and a support rod is fixedly connected to one end of the toothed rod. A brush is fixedly connected to the side of the support rod. This anti-clogging device, through brush cleaning, toothed rod sliding, and gear engagement, ensures that the nozzle does not clog during repeated operation, improving the stability and reliability of the equipment and reducing maintenance costs.

[0013] Furthermore, the gear meshes with the rack, and there is a gap between the circumferential surface of the gear and the circumferential surface of the limiting rod. This gap design between the gear and the limiting rod ensures the stability, reliability, and efficiency of the device during long-term operation by avoiding interference, providing flexibility, reducing wear, and tolerating deformation.

[0014] Furthermore, the bottom of the nozzle is located on the displacement trajectory of the brush. The coordination between the nozzle and the brush displacement trajectory makes the cleaning process more efficient and thorough, while reducing problems such as clogging and wear, and improving the overall operating efficiency and lifespan of the equipment.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model utilizes a motor, threaded rod, threaded sleeve, and limiting rod, among other components, working together to achieve the following: After the spray nozzle of the spraying equipment completes its spraying, the motor is started. The motor drives the threaded rod to rotate, which in turn causes the threaded sleeve to move horizontally under the constraint of the limiting rod. This horizontal movement of the threaded sleeve causes the fixing rod to move horizontally, which in turn causes the compression spring to move horizontally. This horizontal movement of the compression spring causes the arc-shaped scraper to move horizontally, thus evenly smoothing the coating on the steel surface. This achieves the effect of uniformly applying the coating to the surface of the mold steel, making the coating more uniform and improving the consistency of the mold steel.

[0017] 2. This utility model achieves its functionality through the coordinated operation of components such as a motor, threaded rod, gear, and rack. When the motor is started, it drives the threaded rod to rotate. The rotation of the threaded rod drives the gear to rotate, which in turn drives the meshing rack to move horizontally. This horizontal movement of the rack drives the support rod to move horizontally, which in turn drives the brush to move horizontally, thus cleaning the nozzle opening. This ensures that the nozzle does not become clogged during repeated operation, improving the stability and reliability of the equipment and reducing maintenance costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1-5 This utility model is a coating spraying device for heat treatment of mold steel surface, including a base 1, a connecting frame 2 fixedly connected to the top of the base 1, a spraying device 3 set on the top of the connecting frame 2, an adjustment device 4 set on the side of the spraying device 3, a spray nozzle 5 fixedly connected to the bottom of the spraying device 3, a placement groove 6 set on the top of the base 1, and a spreading device 7 set on the top of the base 1.

[0029] The coating spreading device 7 includes a fixed plate 71, the bottom of which is fixedly connected to the top of the base 1. A motor 72 is fixedly connected to the side of the fixed plate 71. A threaded rod 73 is fixedly connected to the output shaft of the motor 72. A threaded sleeve 74 is threadedly connected to the circumferential surface of the threaded rod 73. A fixed rod 75 is fixedly connected to the circumferential surface of the threaded sleeve 74. A compression spring 76 is fixedly connected to the bottom of the fixed rod 75. A fixed seat 77 is fixedly connected to one end of the compression spring 76. An arc-shaped scraper 78 is fixedly connected to the bottom of the fixed seat 77. A limit rod 79 is fixedly connected to the side of the fixed plate 71. This device mainly uses the motor 72 drive and the threaded rod 73 system to ensure that the coating can be evenly applied to the surface of the mold steel, making the coating more uniform and improving the consistency of the mold steel.

[0030] The circumferential surface of the threaded sleeve 74 is slidably connected to the circumferential surface of the limiting rod 79, and multiple compression springs 76 are provided. The sliding connection design allows the threaded sleeve 74 and the limiting rod 79 to move relative to each other, while the function of the compression springs 76 is to adjust the positional accuracy during this movement and prevent the sliding parts from moving excessively or losing alignment.

[0031] Multiple compression springs 76 are arranged linearly along the bottom of the fixed rod 75, and the initial state of the compression springs 76 is relaxed. The initial design of the relaxed state means that the compression springs 76 do not need to bear too much initial compression pressure, avoiding fatigue from being under high pressure for a long time, thereby extending the service life of the springs.

[0032] The top of the placement groove 6 is located on the displacement trajectory of the arc-shaped scraper 78. The design of placing groove 6 on the displacement trajectory of the arc-shaped scraper 78 is mainly to ensure that the arc-shaped scraper 78 always moves along the correct trajectory during operation, thereby improving the stability, accuracy and durability of the equipment.

[0033] An anti-clogging device 8 is installed on the top of the base 1. The anti-clogging device 8 includes a rack 81, the bottom of which is slidably connected to the top of the base 1. A gear 82 is fixedly connected to the circumferential surface of the threaded rod 73. A support rod 83 is fixedly connected to one end of the rack 81, and a brush 84 is fixedly connected to the side of the support rod 83. This anti-clogging device 8, through the cleaning of the brush 84, the sliding of the rack 81, and the engagement of the gear 82, ensures that the nozzle 5 does not become clogged during repeated operation, thereby improving the stability and reliability of the equipment and reducing maintenance costs.

[0034] Gear 82 meshes with rack 81, and there is a gap between the circumferential surface of gear 82 and the circumferential surface of limit rod 79. The gap design between gear 82 and limit rod 79 ensures the stability, reliability and efficiency of the device during long-term operation by avoiding interference, providing flexibility, reducing wear and tolerating deformation.

[0035] The bottom of nozzle 5 is located on the displacement trajectory of brush 84. The coordination between nozzle 5 and the displacement trajectory of brush 84 makes the cleaning process more efficient and thorough, while reducing problems such as clogging and wear, and improving the overall operating efficiency and lifespan of the equipment.

[0036] A specific application of this embodiment is as follows: After the spraying equipment 3 finishes spraying, the motor 72 is started. The motor 72 drives the threaded rod 73 to rotate. The rotation of the threaded rod 73 causes the threaded sleeve 74 to move horizontally under the restriction of the limiting rod 79. The horizontal movement of the threaded sleeve 74 causes the fixing rod 75 to move horizontally. The horizontal movement of the fixing rod 75 causes the compression spring 76 to move horizontally. The horizontal movement of the compression spring 76 causes the arc-shaped scraper 78 to move horizontally. The horizontal movement of the arc-shaped scraper 78 contacts the steel. The arc-shaped scraper 78 then pushes the compression spring 76 to contract, so that the arc-shaped scraper 78 fits against the surface of the steel, thereby evenly smoothing the coating on the surface of the steel.

[0037] The motor 72 is started, which drives the threaded rod 73 to rotate. The rotation of the threaded rod 73 drives the gear 82 to rotate. The rotation of the gear 82 drives the meshing rack 81 to move horizontally. The horizontal movement of the rack 81 drives the support rod 83 to move horizontally. The horizontal movement of the support rod 83 drives the brush 84 to move horizontally. The horizontal movement of the brush 84 cleans the nozzle of the nozzle 5.
