Description
Technical Field
[0001] This utility model belongs to the field of shot blasting machine technology, specifically relating to a shot blasting machine that facilitates the loading and unloading of automotive mold castings. Background Technology
[0002] In industrial production, shot blasting machines, as a key piece of equipment widely used in metal surface treatment, play a vital role in improving product surface quality. In the production process of automotive mold castings, shot blasting machines frequently process castings of various shapes and sizes, which places extremely high demands on the ease of material loading and unloading and the stability of material fixation.
[0003] In the prior art, such as the shot blasting machine with no dead angle disclosed in announcement number CN214265215U, the airflow direction inside the machine body is constantly changing. Correspondingly, the trajectory of the shot thrown by the shot blasting device is also constantly changing, thereby preventing the shot from being unable to perform dead angle processing on the surface of the workpiece due to the shot rotating in the same direction with the workpiece. In addition, the placement plate also moves up and down during rotation, which can further improve the processing effect of the shot blasting machine. The above-mentioned prior art solutions have the following shortcomings: When the above-mentioned shot blasting machine is used, the method of fixing the casting is simple and cannot adapt to the complex and diverse shapes of automotive mold castings. It is difficult to ensure the stable fixing of the casting during the shot blasting process. When the shot blasting machine is running, the casting will be displaced or even fall off, which will not only lead to uneven shot blasting treatment, but also affect the surface quality.
[0004] To address the aforementioned issues, this application proposes a shot blasting machine that facilitates the loading and unloading of automotive mold castings. Utility Model Content
[0005] To address the problems mentioned in the background section, this invention provides a shot blasting machine that facilitates the loading and unloading of automotive mold castings. The clamping plate spacing can be flexibly adjusted according to the casting size to achieve initial clamping. The anti-slip pressure block adapts to the shape and rotation of the casting, increasing friction to prevent horizontal displacement. Multiple sets of anti-slip plates with springs enhance the fixing effect and prevent damage to the casting, achieving stable clamping in both horizontal and vertical directions. During feeding, the electric guide rail drives the slider to automatically and smoothly move the support plate in and out, eliminating the need for manual handling. The speed and stroke can be precisely controlled, significantly shortening the feeding time and greatly improving production efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine that facilitates the entry and exit of automotive mold castings, comprising a shot blasting machine body, and an opening and closing sealing door provided at the feed inlet on one side of the shot blasting machine body;
[0007] A feed base plate is installed at the feed inlet of the shot blasting machine body. A bearing plate is set above the feed base plate. Two clamping plates are symmetrically arranged on the surface of the bearing plate. A threaded sleeve is installed at the bottom of each clamping plate. The two threaded sleeves are slidably connected in the groove opened on the surface of the bearing plate. A dual-shaft motor is installed on the bottom surface of the bearing plate. A lead screw is installed at the two output shaft ends of the dual-shaft motor. The two threaded sleeves are threadedly connected to the surfaces of the two lead screws respectively.

Each pressing block contains an anti-slip pressing block. An arc block is integrally formed on one side of the anti-slip pressing block. An arc groove adapted to the arc block is opened on the surface of the pressing block. The anti-slip pressing block is rotatably connected to one side of the pressing block through the arc block and the arc groove.
[0009] As a preferred embodiment of the shot blasting machine for facilitating the entry and exit of automotive mold castings according to this utility model, a fixing block is fixedly installed on one side of the clamping plate, and a connecting rod is slidably connected to the surface of the fixing block. One end of the connecting rod passes through a groove opened on the surface of the bearing plate and is connected to a wedge seat set at the bottom of the bearing plate. A fixing wedge plate is installed at the bottom of the bearing plate and on one side of the wedge seat. The other end of the connecting rod is connected to a pressure plate set above the bearing plate. A spring is sleeved on the surface of the connecting rod between the fixing block and the pressure plate.
[0010] As a preferred embodiment of the shot blasting machine for facilitating the entry and exit of automotive mold castings according to this utility model, a T-shaped rod is slidably connected in the through hole opened on the surface of the pressure plate. An anti-slip plate is installed at one end of the T-shaped rod that passes through the pressure plate. A second spring is sleeved on the outside of the T-shaped rod. One end of the second spring abuts against the surface of the anti-slip plate, and the other end of the second spring abuts against the pressure plate.
[0011] As a preferred embodiment of the shot blasting machine for facilitating the loading and unloading of automotive mold castings, the surface of the feed base plate is equipped with an electric guide rail, one end of which extends into the main body of the shot blasting machine. A slider is slidably connected to the surface of the electric guide rail, and a connecting frame is installed on the surface of the slider. The connecting frame is fixedly installed at the bottom of the support plate.
[0012] As a preferred embodiment of the shot blasting machine for facilitating the loading and unloading of automotive mold castings, a feeding guide rail is symmetrically installed on the surface of the feeding base plate and on both sides of the electric guide rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This utility model utilizes a combination of structures including a feeding base plate, feeding guide rail, bearing plate, clamping plate, fixed wedge plate, wedge seat, anti-slip plate, pressing block, anti-slip pressing block, slider, and guide wheel. Two clamping plates symmetrically arranged on the surface of the bearing plate move synchronously through a dual-axis motor-driven lead screw and screw sleeve transmission structure. The distance between the clamping plates can be flexibly adjusted according to the different sizes of the casting to achieve initial clamping of the casting. The anti-slip pressing blocks set in multiple pressing blocks on the opposite side of the clamping plates can rotate through the cooperation of arc blocks and arc grooves, adaptively adjusting the angle according to the surface shape of the casting, closely fitting the surface of the casting, increasing the friction with the surface of the casting, and effectively preventing the casting from shifting in the horizontal direction.
[0015] Multiple sets of T-shaped rods with springs and anti-slip plate structures can press against the surface of the casting, which can further enhance the fixing effect of the casting and avoid damage to the surface of the casting.

[0026] 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 protection scope of the present utility model.
[0027] Example
[0028] like Figures 1-6 As shown;
[0029] A shot blasting machine for facilitating the loading and unloading of automotive mold castings includes a shot blasting machine body 1, and a sealing door 2 with an opening and closing gate at the feed inlet on one side of the shot blasting machine body 1.
[0030] A feed base plate 3 is installed at the feed inlet of the shot blasting machine body 1. A bearing plate 6 is set above the feed base plate 3. Two clamping plates 7 are symmetrically arranged on the surface of the bearing plate 6. A threaded sleeve 10 is installed at the bottom of each of the two clamping plates 7. The two threaded sleeves 10 are slidably connected in the grooves opened on the surface of the bearing plate 6. A dual-shaft motor 8 is installed on the bottom surface of the bearing plate 6. A lead screw 9 is installed at each of the two output shaft ends of the dual-shaft motor 8. The two threaded sleeves 10 are threadedly connected to the surfaces of the two lead screws 9 respectively.
[0031] The dual-axis motor 8 drives the lead screw 9 to rotate, which causes the threaded sleeve 10, which is threaded to the lead screw 9 and slides in the grooves of the bearing plate 6, to move the clamping plate 7. This allows for flexible adjustment of the distance between the two clamping plates 7 according to the different sizes of the automotive mold castings, thereby adapting to the clamping requirements of various specifications of castings, improving the versatility of the equipment, ensuring that the clamping plate 7 firmly fixes the castings during shot blasting, preventing the castings from shifting due to vibration or other reasons, and ensuring the effect and quality of shot blasting.
[0032] Multiple pressing blocks 20 are integrally formed on the opposing surfaces of the two clamping plates 7. Each pressing block 20 is provided with an anti-slip pressing block 22. An arc block 23 is integrally formed on one side of the anti-slip pressing block 22. An arc groove 21 adapted to the arc block 23 is opened on the surface of the pressing block 20. The anti-slip pressing block 22 is rotatably connected to one side of the pressing block 20 through the arc block 23 and the arc groove 21.
[0033] The anti-slip pressure block 22 can rotate on one side of the pressure block 20 through the cooperation of the arc block 23 and the arc groove 21. It can adaptively adjust according to the different shapes and angles of the automotive mold casting surface, closely fit the casting surface, and avoid the problem of insecure fixation caused by the irregularity of the casting surface. It improves the fixation effect on complex-shaped castings. The anti-slip pressure block 22 increases the friction with the casting surface. When the shot blasting machine is running, it can effectively prevent the casting from shifting in the horizontal direction, ensure the stability of the casting during the shot blasting process, and thus ensure the uniformity and consistency of the shot blasting quality.
[0034] A fixing block 14 is fixedly installed on one side of the clamping plate 7. A connecting rod 13 is slidably connected to the surface of the fixing block 14. One end of the connecting rod 13 passes through a groove opened on the surface of the bearing plate 6 and is connected to a wedge seat 12 set at the bottom of the bearing plate 6. A fixing wedge plate 11 is installed at the bottom of the bearing plate 6 and on one side of the wedge seat 12. The other end of the connecting rod 13 is connected to a pressure plate 16 set above the bearing plate 6. A spring 15 is sleeved on the surface of the connecting rod 13 and between the fixing block 14 and the pressure plate 16.
[0035] When the clamping plate 7 clamps the casting, the connecting rod 13 on one side of the clamping plate 7 moves accordingly and pushes the wedge seat 12 to move. When the wedge seat 12 contacts the fixed wedge plate 11, the wedge seat 12 can make the connecting rod 13 move downward, causing the pressure plate 16 to press the casting downward. The spring 15 is compressed, further enhancing the fixing effect on the casting. At the same time, the T-shaped rod 17, which is slidably connected in the through hole on the surface of the pressure plate 16, is fitted with a spring 18 on the outside. One end of the spring 18 abuts against the anti-slip plate 19, and the other end abuts against the pressure plate 16. The anti-slip plate 19 can better fit the surface of the casting when the pressure plate 16 is pressed down, preventing the casting from moving in the vertical direction.
[0036] A T-shaped rod 17 is slidably connected in the through hole on the surface of the pressure plate 16. An anti-slip plate 19 is installed at one end of the T-shaped rod 17 that passes through the pressure plate 16. A spring 18 is sleeved on the outside of the T-shaped rod 17. One end of the spring 18 abuts against the surface of the anti-slip plate 19, and the other end of the spring 18 abuts against the pressure plate 16.
[0037] The anti-slip plate 19 is in direct contact with the automotive mold casting. The elasticity of the spring 18 ensures that the anti-slip plate 19 can always fit tightly according to the surface condition of the casting. Regardless of whether the surface of the casting is flat or not, it can provide continuous pressure, which greatly enhances the anti-slip performance and ensures that the casting will not slide due to vibration or other reasons during shot blasting, thus guaranteeing the accuracy of the casting's position during shot blasting.
[0038] An electric guide rail 5 is installed on the surface of the feed base plate 3. One end of the electric guide rail 5 extends into the shot blasting machine body 1. A slider 24 is slidably connected to the surface of the electric guide rail 5. A connecting frame 26 is installed on the surface of the slider 24. The connecting frame 26 is fixedly installed at the bottom of the support plate 6.
[0039] The electric guide rail 5 provides power to drive the slider 24, allowing the support plate 6 to move automatically in and out of the shot blasting machine body 1 along the guide rail. Compared with traditional manual handling or simple manual operation, this automated entry and exit method greatly reduces manpower input and reduces the labor intensity of workers. The slider 24 slides smoothly on the electric guide rail 5, allowing the support plate 6 to enter and exit the shot blasting machine body 1 according to the preset path and speed, reducing the problem of casting collision and damage caused by shaking or deviation.
[0040] Feeding guide rails 4 are symmetrically installed on the surface of the feeding base plate 3 and on both sides of the electric guide rail 5. Guide wheels 25 are installed at the bottom of the bearing plate 6. The bearing plate 6 is slidably connected to the surface of the feeding guide rail 4 through the guide wheels 25.
[0041] The guide wheel 25 has a high sliding fit with the feed guide rail 4, which can accurately control the movement trajectory of the support plate 6. This allows the support plate 6 to accurately reach the predetermined position when entering and exiting the shot blasting machine body 1, ensuring the positional accuracy of the casting in the shot blasting chamber. Accurate positioning is crucial to the effect of shot blasting, ensuring that the shot acts evenly on the surface of the casting, improving the shot blasting quality, and making the surface treatment of the casting more consistent and uniform.
[0042] The working principle and usage process of this utility model are as follows: First, initially, the opening and closing sealing door 2 is in the closed state, the bearing plate 6 is located on the feeding bottom plate 3, and has not entered the shot blasting machine body 1. The automobile mold casting is placed on the bearing plate 6, and the dual-axis motor 8 on the bottom surface of the bearing plate 6 is started. The two output shafts of the dual-axis motor 8 drive the lead screw 9 to rotate. Since the two threaded sleeves 10 are respectively threaded to the surfaces of the two lead screws 9, and the threaded sleeves 10 are slidably connected in the grooves opened on the surface of the bearing plate 6, when the lead screw 9 rotates, the threaded sleeves 10 will move in the grooves, thereby driving the clamping plate 7 to move, so that the two clamping plates 7 move closer to the casting until the casting is initially clamped.
[0043] When the clamping plate 7 approaches the casting, the anti-slip pressing block 22 can rotate and adjust its angle according to the surface shape of the casting to better fit the surface of the casting, increase friction, and prevent the casting from sliding during shot blasting.
[0044] When the clamping plate 7 clamps the casting, the connecting rod 13 on one side of the clamping plate 7 moves and pushes the wedge seat 12 to move. When the wedge seat 12 contacts the fixed wedge plate 11, the wedge seat 12 can make the connecting rod 13 move downward, which drives the pressure plate 16 to press the casting downward. The spring 15 is compressed, which further enhances the fixing effect on the casting. At the same time, the T-shaped rod 17 slidably connected in the through hole on the surface of the pressure plate 16 is fitted with a spring 18 on the outside. One end of the spring 18 abuts against the anti-slip plate 19, and the other end abuts against the pressure plate 16. The anti-slip plate 19 can better fit the surface of the casting when the pressure plate 16 is pressed down, preventing the casting from moving in the vertical direction.
[0045] After the casting is fixed, the electric guide rail 5 on the surface of the feed base plate 3 is activated. The slider 24 on the surface of the electric guide rail 5 drives the connecting frame 26 and the bearing plate 6 to move along the electric guide rail 5 into the shot blasting machine body 1. At the same time, the guide wheel 25 at the bottom of the bearing plate 6 slides on the surface of the feed guide rail 4, which plays an auxiliary guiding role and ensures that the bearing plate 6 enters the shot blasting machine body 1 smoothly. When the bearing plate 6 reaches the predetermined position, the electric guide rail 5 stops running, the opening and closing sealing door 2 is closed, and the shot blasting process begins.
[0046] After shot blasting is completed, open the sealing door 2, the electric guide rail 5 runs in reverse, and drives the bearing plate 6 to move out of the shot blasting machine body 1 until it returns to the initial position of the feed bottom plate 3. Close the electric guide rail 5, and then make the dual-axis motor 8 reverse to loosen the fixation of the casting, take out the casting, and complete one shot blasting operation.
[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
