Description

Technical Field

[0001] The utility model relates to the technical field of automobile mold production, and particularly relates to a surface treatment device for automobile mold production. Background Technique

[0002] Automobile molds, in a narrow sense, refer to the general term for all stamping molds for automobile body parts. That is, "automobile body stamping molds". For example, the top cover flanging mold, the crossbeam reinforcement plate forming mold, etc. When producing automobile molds, it is necessary to polish the surface of the automobile molds to make the surface of the automobile molds smooth, so that the surface of the stamped parts is smooth and clean, ensuring the quality of the stamped parts. And the sandblasting machine is the best choice for the surface treatment equipment in automobile mold production.

[0003] The sandblasting machine uses compressed air in the pipeline to transport powdery particles (with a diameter of 1-4 mm) from one place to another. During the process of converting kinetic energy into potential energy, the high-speed moving sand grains scour the surface of the object to achieve the effect of improving the surface quality of the object. In order to prevent the sand grains from splashing everywhere, the sandblasting machine usually performs sandblasting operations in a closed box. However, the volume of automobile molds is usually large and heavy, so it is difficult to put them into the box of the sandblasting machine. A mold sandblasting machine disclosed in Chinese Patent CN219054055U can place the mold on the placement table and then push it into the sandblasting machine body, which can facilitate the placement of the automobile mold into the sandblasting machine box. However, while solving the problem, this mold sandblasting machine has the following defects:

[0004] The surface of the automobile mold is usually uneven, while the placement table is horizontal. Therefore, during sandblasting and polishing, the sand grains will remain in the grooves on the surface of the automobile mold, thereby buffering the impact force of the subsequent sand grains, making the surface treatment of the automobile mold incomplete and affecting the quality of the surface treatment of the automobile mold. Summary of the Utility Model

[0005] The purpose of the present utility model aims to solve at least one of the technical defects described in the background technique.

[0006] Therefore, an object of the present utility model is to provide a surface treatment device for automobile mold production, aiming to solve the problem that when the existing mold sandblasting machine processes automobile molds, the sand grains will remain in the grooves on the surface of the automobile mold, affecting the quality of the surface treatment of the automobile mold.

[0007] To achieve the above object, an embodiment of one aspect of the present utility model provides a surface treatment device for automotive mold production, including a chassis, a support frame, a chassis and a fixing table. An inlet slot is provided on one side of the chassis. Rails are fixedly connected to the inner walls on both sides of the chassis. Roller wheels are rotatably connected to both sides of the support frame. The support frame is slidably connected in the rails through the roller wheels. A door panel is fixedly connected to one side of the support frame. Rotating shafts are fixedly connected to both sides of the chassis. The chassis is rotatably connected to the inside of the support frame through the rotating shafts. A positioning shaft is fixedly connected to the center of the bottom of the fixing table. A positioning hole is provided at the center of the chassis. The fixing table is rotatably connected in the positioning hole through the positioning shaft. A worm gear is fixedly connected to the outer surface of the rotating shaft. A bracket is fixedly connected to one side of the support frame. A first motor is fixedly installed at the bottom of the bracket. A worm is fixedly connected to the output end of the first motor. The worm meshes with the worm gear. A driven gear is fixedly connected to the outer surface of the positioning shaft. A second motor is fixedly installed at the bottom of the chassis. A gear is fixedly connected to the output end of the second motor. The gear meshes with the driven gear. An inclined slide rail is fixedly installed at the top of the inner wall of the chassis. A slider is slidably connected in the slide rail. A sandblasting head is fixedly installed on one side of the slider.

[0008] Preferably, a circular groove is provided at the top of the chassis. A plurality of limiting blocks are fixedly connected to the bottom of the fixing table. The limiting blocks are slidably connected inside the circular groove to assist the positioning shaft in supporting the fixing table and improve the stability of the rotation of the fixing table. A ball is provided at the top of the chassis to reduce the friction between the fixing table and the chassis, so that the fixing table rotates more smoothly.

[0009] Preferably, a chute is provided at the top of the fixing table. A sliding seat is slidably connected inside the chute. A clamping plate is fixedly connected to the top of the sliding seat. A positioning bolt is threadedly connected to the top of the sliding seat. A positioning seat is rotatably connected to the outer surface of the positioning bolt. Tooth grooves are provided on both sides of the chute. A rack is fixedly connected to the bottom of the positioning seat, which can fix the clamping plate more firmly, so as to ensure that the automotive mold on the fixing table does not slide in an inclined state.

[0010] Preferably, a third motor is fixedly installed at one end of the slide rail. A lead screw is fixedly connected to the output end of the third motor. The lead screw is threadedly connected inside the slider. An inclined electric push rod is fixedly installed at the top of the inner wall of the chassis. The output end of the electric push rod is fixedly connected to the slide rail, which can treat the surfaces of automotive molds with different thicknesses.

[0011] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0012] 1. The first motor drives the worm gear to rotate through a worm, thereby driving the chassis to rotate, causing the automotive mold on the fixed table to tilt. As a result, the sand grains ejected by the sandblasting head and the removed burrs will slide down along the inclined surface of the automotive mold and will not stay on the surface of the automotive mold, enabling more thorough surface treatment of the automotive mold and ensuring the quality of surface treatment of the automotive mold.

[0013] 2. When fixing the positioning seat, the rack is inserted into the tooth groove. Thus, for automotive molds with relatively heavy weights, even when the fixed table is in an inclined state, the clamping plate can still provide sufficient clamping force for it, avoiding the problem of the positioning seat sliding and causing the automotive mold to slide off, and improving the reliability of the structure.

[0014] 3. The limiting block is slidably connected inside the annular groove. Thus, the limiting block can assist the positioning shaft in supporting the fixed table. When the fixed table is in an inclined state, the limiting block can enhance the firmness of the structure, and the ball can reduce the friction between the fixed table and the chassis, making the rotation of the fixed table smoother.

[0015] 4. By setting the electric push rod, the electric push rod can drive the slide rail to approach or move away from the inclined fixed table. Thus, for automotive molds with different thicknesses, the electric push rod can make the slide rail maintain an appropriate distance from the automotive mold, ensuring the quality of sandblasting treatment.

[0029] Embodiment 1:

[0030] As Figures 1-6As shown in the figure, it includes a chassis 1, a support frame 2, a chassis 3 and a fixing table 4. An inlet slot 11 is provided on one side of the chassis 1. Inner walls on both sides of the chassis 1 are fixedly connected with tracks 12. Both sides of the support frame 2 are rotatably connected with rollers 21. The support frame 2 is slidably connected in the tracks 12 through the rollers 21. One end of the track 12 far from the chassis 1 is fixedly connected with a limiting rod 121 to prevent the support frame 2 from slipping off the track 12. One side of the support frame 2 is fixedly connected with a door panel 22. After the support frame 2 is pushed into the interior of the chassis 1, the door panel 22 can block the inlet slot 11, thus avoiding the problem of sand particles splashing out. Both sides of the chassis 3 are fixedly connected with rotating shafts 31. The chassis 3 is rotatably connected inside the support frame 2 through the rotating shafts 31. The center of the bottom of the fixing table 4 is fixedly connected with a positioning shaft 41. A positioning hole 33 is provided at the center of the chassis 3, enabling the angle of the chassis 3 to be adjustable. The fixing table 4 is rotatably connected in the positioning hole 33 through the positioning shaft 41, enabling the fixing table 4 to rotate. The outer surface of the rotating shaft 31 is fixedly connected with a worm gear 32. One side of the support frame 2 is fixedly connected with a bracket 23. The bottom of the bracket 23 is fixedly installed with a first motor 24. A second avoidance slot 14 is provided on one side of the chassis 1. When the support frame 2 enters the interior of the chassis 1, the bracket 23 enters the second avoidance slot 14 to avoid the bracket 23 affecting the movement of the support frame 2. The output end of the first motor 24 is fixedly connected with a worm 25. The worm 25 meshes with the worm gear 32. The first motor 24 drives the worm gear 32 to rotate through the worm 25, thereby adjusting the inclination angle of the chassis 3 and the fixing table 4. The outer surface of the positioning shaft 41 is fixedly connected with a driven gear 42. The bottom of the chassis 3 is fixedly installed with a second motor 34. A first avoidance slot 13 is provided below the inlet slot 11, enabling the second motor 34 to enter the interior of the chassis 1 from the outside of the chassis 1. The output end of the second motor 34 is fixedly connected with a gear 35. The gear 35 meshes with the driven gear 42. The second motor 34 can drive the driven gear 42 to rotate through the gear 35, thereby achieving the purpose of rotating the fixing table 4. The top of the inner wall of the chassis 1 is fixedly installed with an inclined slide rail 6. A slider 61 is slidably connected inside the slide rail 6. One side of the slider 61 is fixedly installed with a sandblasting head 62. The sandblasting head 62 can slide along with the slider 61, thereby achieving the purpose of adjusting the position of the sandblasting head 62.

[0031] Specifically, a transparent window 19 is provided on one side of the chassis 1 to facilitate observing the processing situation inside the chassis 1.

[0032] Specifically, as Figure 1 shown, positioning rods 26 are fixedly connected to both sides of the door panel 22. Hooks 15 are rotatably connected to both sides of the chassis 1. After the support frame 2 enters the chassis 1, by rotating the hooks 15, they are hung on the surface of the positioning rods 26, thereby positioning the door panel 22 and avoiding the problem that the support frame 2 slides out of the chassis 1 during the processing.

[0033] Specifically, asFigure 2 As shown in the figure, a support beam 16 is fixedly connected to the inner wall of the chassis 1. When the chassis 3 is in an inclined state, the support beam 16 supports the bottom of the chassis 3.

[0034] Specifically, as Figure 2 shown in the figure, a hopper 17 is fixedly connected to the inner wall of the chassis 1, which is used to collect sand grains and debris ground from the surface of the automotive mold. A return pipe 18 is fixedly connected below the hopper 17 for discharging sand grains and debris.

[0035] Specifically, as Figure 5 shown in the figure, a chute 43 is opened at the top of the fixed table 4. A sliding seat 5 is slidably connected inside the chute 43. A clamping plate 51 is fixedly connected to the top of the sliding seat 5. A positioning bolt 52 is threadedly connected to the top of the sliding seat 5. A positioning seat 53 is rotatably connected to the outer surface of the positioning bolt 52. A through hole is opened on the positioning seat 53. The positioning seat 53 is sleeved on the outer surface of the positioning bolt 52 through the through hole. By rotating the positioning bolt 52, the positioning seat 53 presses down on the fixed table 4, so as to fix the position of the sliding seat 5.

[0036] Further preferably, as Figures 5-6 shown in the figure, tooth grooves 44 are provided on both sides of the chute 43. A rack 54 is fixedly connected to the bottom of the positioning seat 53. When fixing the positioning seat 53, the rack 54 is inserted into the tooth groove 44, thus avoiding the problem of the positioning seat 53 sliding.

[0037] Embodiment 2:

[0038] As Figures 5-6 shown in the figure, on the basis of Embodiment 1, an annular groove 36 is opened at the top of the chassis 3. A plurality of limiting blocks 45 are fixedly connected to the bottom of the fixed table 4. The limiting blocks 45 are slidably connected inside the annular groove 36. When the fixed table 4 is in an inclined state, the limiting blocks 45 assist the positioning shaft 41 to support the fixed table 4, thereby improving the firmness of the structure. A ball 37 is arranged on the top of the chassis 3. The ball 37 supports the fixed table 4. When the fixed table 4 is in a rotating state, the ball 37 rolls along with the fixed table 4, thereby reducing the friction force and making the fixed table 4 rotate more smoothly.

[0039] Embodiment 3:

[0040] As Figure 2 and Figure 7As shown in the figure, on the basis of the first or second embodiment, a third motor 63 is fixedly installed at one end of the slide rail 6. The output end of the third motor 63 is fixedly connected to a lead screw 64. The lead screw 64 is threadedly connected to the inside of the slider 61. The third motor 63 drives the lead screw 64 to rotate inside the slider 61, so as to drive the slider 61 to move. An inclined electric push rod 65 is fixedly installed at the top of the inner wall of the chassis 1. The output end of the electric push rod 65 is fixedly connected to the slide rail 6. The electric push rod 65 can adjust the distance between the slide rail 6 and the fixed table 4 by telescoping, so as to be applicable to automotive molds of different thicknesses.

[0041] The working principle of the present utility model is as follows: When in use, place the automotive mold above the fixed table 4, then slide the sliding seat 5 backward so that the clamping plate 51 abuts against the edge of the automotive mold, rotate the positioning bolt 52 so that the positioning seat 53 presses against the fixed table 4, and the rack 54 is inserted into the tooth groove 44 to fix the sliding seat 5. Then push the door panel 22 to push the support frame 2 into the chassis 1, rotate the hook 15 to hang it on the surface of the positioning rod 26 to fix the door panel 22. Then drive the chassis 3 to rotate through the first motor 24 so that the fixed table 4 is inclined, and thus the automotive mold fixed on the fixed table 4 is inclined. Finally, extend the electric push rod 65 to make the sandblasting head 62 close to the surface of the automotive mold, and then spray sand grains onto the surface of the automotive mold. And the second motor 34 drives the fixed table 4 to rotate so that the automotive mold rotates, and the third motor 63 drives the lead screw 64 to rotate so that the sandblasting head 62 slides, thereby processing the burrs on the surface of the automotive mold.

[0042] Compared with the prior art, the present utility model has the following beneficial effects compared with the prior art:

[0043] 1. When processing the surface of the automotive mold, after pushing the support frame 2 into the chassis 1, the first motor 24 drives the worm wheel 32 to rotate through the worm 25, thereby driving the chassis 3 to rotate, making the automotive mold on the fixed table 4 inclined. Then, the burrs on the surface of the automotive mold are processed by the sandblasting head 62. The sand grains sprayed by the sandblasting head 62 and the removed burrs will slide down along the inclined surface of the automotive mold and will not stay on the surface of the automotive mold, so that the surface of the automotive mold can be processed more thoroughly, ensuring the quality of the surface treatment of the automotive mold.

[0044] 2. By providing the tooth groove 44 and the rack 54, when fixing the positioning seat 53, the rack 54 is inserted into the tooth groove 44. Thus, for a heavier automotive mold, when the fixed table 4 is inclined, the clamping plate 51 can still provide sufficient clamping force for it, avoiding the problem that the positioning seat 53 slides and causes the automotive mold to slide, and improving the reliability of the structure.

[0045] 3. By setting the annular groove 36 and the limiting block 45, the limiting block 45 is slidably connected inside the annular groove 36, so that the limiting block 45 can assist the positioning shaft 41 to support the fixed table 4. Thus, when the fixed table 4 is in an inclined state, the limiting block 45 can improve the structural firmness, and the ball 37 can reduce the friction between the fixed table 4 and the chassis 3, making the fixed table 4 rotate more smoothly.

[0046] 4. By setting the electric push rod 65, the electric push rod 65 can drive the slide rail 6 to approach or move away from the inclined fixed table 4. Thus, for automotive molds of different thicknesses, the electric push rod 65 can ensure that the slide rail 6 maintains an appropriate distance from the automotive mold, thereby ensuring the quality of sandblasting treatment.
