Description

Technical Field

[0001] This invention relates to the field of mold processing equipment technology, specifically to a device and method for correcting the fit of upper and lower mold assembly. Background Technology

[0002] Before leaving the factory, the finished upper and lower molds need to undergo a fit test. The traditional test method is as follows: The worker applies marking paint to the upper surface of the upper mold, then lifts the upper mold and moves the lower mold directly below it. The upper mold is then lowered so that the upper and lower molds are in place. At this point, the upper and lower surfaces fit together, and the marking paint adheres to the lower surface. After the fit is complete, the upper mold is lifted, and the worker observes the paint on the lower surface of the lower mold. If the fit is up to standard, the lower surface will be covered with paint. If the fit is not up to standard, there will be blank areas on the lower surface. Blank areas indicate that some areas of the lower mold have protruding parts, which prevent some areas of the lower surface from contacting the upper surface.

[0003] For substandard lower molds, workers need to use grinding equipment to clean the protruding parts. After grinding, the mold is closed and tested to determine whether there is paint in the previously blank areas.

[0004] However, the above-mentioned repair method has the following problems: 1. During the second inspection, the paint on the upper surface will be partially dried, resulting in poor adhesion; 2. The paint from the first inspection will interfere with the second inspection, affecting the worker's judgment; 3. The debris from grinding will affect the fitting accuracy, resulting in insufficient calibration accuracy.

[0005] In summary, there is a need for a device that can correct the fit of the upper and lower mold assembly with higher accuracy. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a device for correcting the fit of upper and lower mold assembly, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The upper and lower mold assembly fit correction device includes an assembly base. A first moving groove is formed at the transverse centerline of the surface of the assembly base. A mold pushing component is installed inside the first moving groove. The surface of the assembly base is provided with an assembly position and a grinding position. A grinding auxiliary component is provided at the bottom surface of the hanger relative to the grinding position. A spray washing integrated component is provided at the side of the assembly base relative to the assembly position. A hanger is provided at the top of the assembly base. A mold lifting component is provided at the bottom surface of the hanger relative to the assembly position.

[0009] The mold lifting assembly includes a fixed plate, a pneumatic rod, side lifting plates, and a traction motor. The pneumatic rod runs through the inside of the frame, and the bottom end of the pneumatic rod is connected to the fixed plate. Both ends of the bottom surface of the fixed plate are vertically provided with side lifting plates, which are located at the front and rear sides of the assembly position, respectively.

[0010] The side hanging plate has vertical and horizontal sliding grooves inside, which are L-shaped. Vertical sliders are slidably installed inside the vertical sliding grooves, and horizontal sliders are slidably installed inside the horizontal sliding grooves. The two vertical sliders are used to assemble and connect with the upper mold with the upper mold facing down. The two horizontal sliders are used to assemble and connect with the lower mold. A traction motor is located at the center of the surface of the fixed plate. The traction motor is connected to the vertical sliders. The horizontal sliders can move along the horizontal sliding grooves. When they move to the end, they rotate the lower mold, so that the lower mold is misaligned with the bottom side of the upper mold with the lower mold facing down. The spray-washing integrated component is used to spray-wash and air-dry the upper and lower mold surfaces.

[0011] Furthermore, the spray-washing integrated assembly has three states: In the first state, the spray-washing integrated assembly is located directly below the upper mold, and is used to spray marking paint onto the upper surface of the upper mold; In the second state, the spray-washing integrated assembly is located directly below both the upper and lower molds, and is used to simultaneously clean the marking paint from both the upper and lower surfaces; In the third state, the spray-washing integrated assembly is located directly above the storage tank.

[0012] Furthermore, both the horizontal and vertical sliders are I-shaped. A first locking screw passes through the center hole of the vertical slider and its end is screwed into the side wall of the upper mold. An inner sleeve passes through the center of the horizontal slider. The inner wall of the inner sleeve is distributed with internal threads. A second locking screw passes through the internal threads of the inner sleeve and its end is screwed into the side wall of the lower mold.

[0013] Furthermore, the inner wall of the transverse slide is provided with a slot, which is aligned with the vertical slide, and a baffle to stop the transverse slide is inserted inside the slot.

[0014] Furthermore, the spray washing integrated component includes a storage box, a tray, a sliding plate, a first motor, and a second motor. The storage box is located on the side of the assembly base. A second moving groove is opened on the surface of the storage box. A sliding plate is vertically slidably embedded inside the second moving groove. A horizontally distributed screw is threaded through the internal thread of the sliding plate. The end of the screw is connected to the second motor. A tray is provided at the top of the sliding plate near the side wall of the assembly base. The tray is spaced above the assembly base and the storage box. The second motor drives the screw to rotate, thereby causing the tray to extend to the assembly position or retract to the top of the storage box.

[0015] The storage box contains a paint tank, a cleaning fluid tank, a recycling tank, and a fan box. The tray contains a spray pipe, a cleaning pipe, and an air duct. The paint tank is connected to the spray pipe via a first flexible hose, the cleaning fluid tank is connected to the cleaning pipe via a second flexible hose, the bottom of the tray is connected to the recycling tank via a third flexible hose, and the inlet end of the air duct is connected to the fan box via a fourth flexible hose. The first, second, third, and fourth flexible hoses pass through the slide plate and the storage box.

[0016] Furthermore, the spraying pipe, cleaning pipe, and air duct are arranged in a linear array at intervals. The length of the spraying pipe is half the length of the cleaning pipe, the length of the cleaning pipe is the same as the length of the air duct, and the length of the cleaning pipe is the same as the sum of the lengths of the upper mold and the lower mold.

[0017] The operation method of the upper and lower mold assembly fit correction device includes the following steps:

[0018] S1. Upper mold assembly:

[0019] Place the upper mold inside the mold pushing assembly;

[0020] The pneumatic rod drives the side hanging plate to move downward until the vertical slider is aligned with the upper mold. Then, the first locking screw is tightened to connect the vertical slider and the upper mold into one piece.

[0021] S2. Upper mold spraying treatment:

[0022] The tray moves to the bottom of the upper mold, and the spray nozzle sprays the marking paint upward onto the upper surface of the upper mold. After the spraying is completed, the tray returns to the top of the storage box.

[0023] Place the lower mold inside the mold pushing assembly;

[0024] The mold lifting assembly drives the upper mold to move downward, so that the upper mold and the lower mold are assembled into one piece, and the marking paint on the upper mold surface adheres to the lower mold surface that is in contact with it;

[0025] S3. Compatibility test:

[0026] The mold lifting assembly moves the upper mold upward, separating the upper mold from the lower mold. Workers then observe the lower mold surface to determine if there are any areas on the lower mold surface without any marking paint.

[0027] No, if the lower surface is completely covered with the marking paint, the fit is qualified, and proceed to S5;

[0028] Yes, the lower surface is not completely covered with the marking paint, and the local fit is unqualified, so proceed to S4;

[0029] S4. Handling of substandard molds:

[0030] S4.1 Lower Surface Trimming:

[0031] The mold is moved to a position below the grinding auxiliary component by the mold pushing component; the protruding parts are then ground using grinding tools.

[0032] S4.2 Transfer the trimmed lower mold to the assembly position for finishing and painting:

[0033] S4.3, Repeat S3;

[0034] S5. Qualified mold processing:

[0035] Clean the marking paint from the upper and lower mold surfaces:

[0036] After cleaning is complete, unscrew the first and second locking screws, and remove the qualified upper and lower molds.

[0037] This invention provides a device for correcting the fit of upper and lower mold assembly. Compared with the prior art, it has the following advantages:

[0038] 1. It can meet the needs of mold lifting, mold transfer and mold trimming at each stage of mold fit calibration, thereby effectively reducing the amount of manual mold transfer and improving conversion efficiency;

[0039] 2. By deploying the spray cleaning integrated component, the upper and lower surfaces of the mold can be cleaned and dried. During cleaning, the marking paint and grinding debris from the previous inspection are removed, ensuring the accuracy of the next inspection. The spray cleaning integrated component is deployed on the side of the assembly base and extends to the assembly position during use, without affecting the normal assembly and transfer of the upper and lower molds.

[0040] 3. The lower mold can move laterally along the side hanging plate and then flip over. In this way, the lower mold can be placed on the bottom side of the upper mold. At this time, both the lower and upper mold surfaces are facing down. Thus, the spray washing integrated component can simultaneously cover the lower and upper mold surfaces to achieve synchronous cleaning and drying of the upper and lower mold surfaces, effectively improving cleaning efficiency and eliminating errors.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1

[0056] To address the technical problems in the background art, the following upper and lower mold assembly fit correction device is provided:

[0057] Combination Figures 1-11 As shown, the upper and lower mold assembly fit correction device provided by the present invention includes an assembly base 1. A first moving groove 11 is provided at the transverse center line of the surface of the assembly base 1. A mold pushing component is installed inside the first moving groove 11. The surface of the assembly base 1 is provided with an assembly position and a grinding position. A grinding auxiliary component 3 is provided at the bottom surface of the hanger 8 opposite to the grinding position. A spray washing integrated component 4 is provided at the side of the assembly base 1 opposite to the assembly position. A hanger 8 is provided at the top of the assembly base 1. A mold lifting component 2 is provided at the bottom surface of the hanger 8 opposite to the assembly position.

[0058] The mold lifting assembly 2 includes a fixed plate 21, a pneumatic rod 22, side lifting plates 23, and a traction motor 24. The pneumatic rod 22 runs through the interior of the lifting frame 8. The bottom end of the pneumatic rod 22 is connected to the fixed plate 21. The bottom surfaces of the fixed plate 21 are vertically provided with side lifting plates 23 at both ends. The two side lifting plates 23 are located on the front and rear sides of the assembly position, respectively.

[0059] The side hanging plate 23 has a vertical slide groove 231 and a horizontal slide groove 232 inside. The vertical slide groove 231 and the horizontal slide groove 232 are L-shaped. A vertical slider 233 is slidably installed inside the vertical slide groove 231, and a horizontal slider 234 is slidably installed inside the horizontal slide groove 232. The two vertical sliders 233 are used to assemble and connect with the upper mold 6, with the upper surface of the upper mold 6 facing down. The two horizontal sliders 234 are used to assemble and connect with the lower mold 7. A traction motor 24 is provided at the center of the surface of the fixing plate 21. The traction motor 24 is connected to the vertical sliders 233 through a traction rope. The horizontal sliders 234 can move along the horizontal slide groove 232. When they move to the end, they rotate the lower mold 7, so that the lower mold 7 is misaligned with the bottom side of the upper mold 6 with the lower surface facing down. The spray washing integrated component 4 is used to spray, wash and air dry the upper and lower surfaces.

[0060] The spray-washing integrated assembly 4 has three states: In the first state, the spray-washing integrated assembly 4 is located directly below the upper mold 6, and is used to spray marking paint onto the upper surface of the upper mold 6; In the second state, the spray-washing integrated assembly 4 is located directly below the upper mold 6 and the lower mold 7, and is used to clean the marking paint from the upper and lower surfaces simultaneously; In the third state, the spray-washing integrated assembly 4 is located directly above the storage box 41.

[0061] The above-mentioned device can meet the needs of mold lifting, mold transfer and mold trimming at each stage of mold fit correction, thereby effectively reducing the amount of manual mold transfer and improving conversion efficiency.

[0062] By deploying the spray washing integrated component 4, the upper and lower surfaces of the mold can be cleaned and dried. During cleaning, the marking paint and grinding debris from the previous inspection are removed, ensuring the accuracy of the next inspection. The spray washing integrated component 4 is deployed on the side of the assembly base 1 and extends to the assembly position during use, without affecting the normal assembly and transfer of the upper and lower molds.

[0063] The lower mold 7 can move laterally along the side hanging plate 23 and then flip over. In this way, the lower mold 7 can be placed on the bottom side of the upper mold 6. At this time, both the lower and upper mold surfaces are facing down. Thus, the spray washing integrated component 4 can simultaneously cover the lower and upper mold surfaces to achieve synchronous cleaning and drying of the upper and lower mold surfaces, effectively improving cleaning efficiency and eliminating errors.

[0064] In this embodiment, both the horizontal slider 234 and the vertical slider 233 are I-shaped. The central hole of the vertical slider 233 is through which a first locking screw 2331 passes and its end is screwed into the side wall of the upper mold 6. The center of the horizontal slider 234 is through which an inner sleeve 2341 passes. The inner wall of the inner sleeve 2341 is distributed with internal threads. The internal threads of the inner sleeve 2341 are through which a second locking screw 2342 passes and its end is screwed into the side wall of the lower mold 7.

[0065] By arranging independent vertical sliders 233 and vertical slides 231, the upper mold 6 can be driven to move with the mold lifting assembly 2. The vertical slider 233 can be raised and lowered synchronously with the side hanging plate 23, or the vertical slider 233 can be driven to move independently along the slide by the traction motor 24, so as to meet the need to separate the upper and lower molds during the flipping of the lower mold 7.

[0066] By arranging independent horizontal sliders 234, horizontal slides 232, and inner sleeves 2341, the lower mold 7 can be vertically raised and lowered with the side hanging plate 23, and can also move independently along the horizontal slides 232. After reaching the end, it can be independently flipped so that the lower mold surface faces down, so that it can be cleaned and dried simultaneously.

[0067] In this embodiment, the inner wall of the transverse slide 232 is provided with a slot 2321, which is aligned with the vertical slide 231. A baffle 2322 that stops the transverse slider 234 is inserted inside the slot 2321.

[0068] By designing the baffle 2322, the baffle 2322 can stop the horizontal slider 234 during the hoisting stage, so that the horizontal slider 234 can stably support the vertical slider 233 and ensure the stability of the connection between the vertical slider 233 and the upper mold 6.

[0069] The mold pushing assembly includes a conveyor belt 5 and a pusher plate 51. The conveyor belt 5 is embedded in the assembly base 1. Two pusher plates 51 are vertically spaced on the surface of the conveyor belt 5 and pass through the first moving groove 11. The mold is placed in the two pusher plates 51. When the conveyor belt 5 is working, it can drive the mold to move through the pusher plates 51.

[0070] Example 2

[0071] like Figures 1-11 As shown, based on the above embodiments, this embodiment further provides the following:

[0072] To enable the spray-wash integrated component 4 to perform the integrated functions of spraying, washing, and drying, the following design scheme is proposed:

[0073] In this embodiment, the spray washing integrated assembly 4 includes a storage box 41, a tray 42, a sliding plate 44, a first motor, and a second motor 43. The storage box 41 is located on the side of the assembly base 1. A second moving groove 411 is formed on the surface of the storage box 41. The sliding plate 44 is vertically slidably embedded inside the second moving groove 411. Horizontally distributed screws 431 are threaded through the inside of the sliding plate 44. The end of the screws 431 is connected to the second motor 43. The top of the sliding plate 44 is provided with a tray 42 near the side wall of the assembly base 1. The trays 42 are spaced apart above the assembly base 1 and the storage box 41. The second motor 43 drives the screws. 431 rotates, thereby causing the tray 42 to extend to the assembly position or retract to the top of the storage box 41; the storage box 41 is equipped with a paint tank, a cleaning fluid tank, a recycling tank, and a fan box; the tray 42 is equipped with a spray pipe 421, a cleaning pipe 422, and an air duct 423; the paint tank is connected to the spray pipe 421 through a first hose, the cleaning fluid tank is connected to the cleaning pipe 422 through a second hose, the bottom surface of the tray 42 is connected to the recycling box through a third hose, and the inlet end of the air duct 423 is connected to the fan box through a fourth hose; the first hose, the second hose, the third hose, and the fourth hose pass through the slide plate 44 and the storage box 41.

[0074] In this embodiment, the spraying pipe 421, cleaning pipe 422, and air duct 423 are arranged in a linear array at intervals. The length of the spraying pipe 421 is half the length of the cleaning pipe 422. The length of the cleaning pipe 422 is the same as the length of the air duct 423. The length of the cleaning pipe 422 is the same as the sum of the lengths of the upper mold 6 and the lower mold 7.

[0075] The tray 42 is designed to hold paint and cleaning fluids during the process, preventing the workbench from getting dirty. The collected waste liquid can be recycled to the recycling bin through a hose.

[0076] By setting up independent paint tanks 412, cleaning fluid tanks 413, and fan boxes 414, they can work independently according to the needs of the operation stage without affecting each other; since the spray pipe 421 only needs to treat the upper surface, its coverage length only needs to be the same as the upper surface.

[0077] Example 3

[0078] like Figures 1-11 As shown, based on the above embodiments, this embodiment further provides the following:

[0079] The following problems exist during the finishing process: 1. When the parts have many details and the paint is light, observation is difficult; 2. Sand is easily generated during sanding, affecting observation. The following solutions are proposed to address these problems:

[0080] The grinding auxiliary component 3 includes an upper tube body 31, a fixed base 32, a lower tube body 33, a lighting lamp 34, and a filter plate 35. The top end of the lower tube body 33 is slidably embedded in the upper tube body 31. The top surface of the upper tube body 31 is provided with a connecting frame 311, which is rotatably connected to the fixed base 32. The fixed base 32 is located on the bottom surface of the hanger 8. The lower tube body 33 includes a main tube body 331, a fan box 332, and a dust suction hood 333. The top end of the main tube body 331 is provided with a fan box 332, and the bottom end is provided with a dust suction hood 333. The fan box 332 is damped and slidably embedded in the upper tube body 31. The interior of the main tube body 331 is provided with multiple filter plates 35, and the interior of the dust suction hood 333 is equipped with a lighting lamp 34.

[0081] When no processing is required, the lower tube 33 is retracted into the upper tube 31 without affecting the input of the lower mold 7;

[0082] When repair is needed, the lower pipe 33 can be pulled down or rotated so that the lighting 34 is aimed at the defective area for workers to observe; by installing the fan box 332, negative pressure can be used to attract debris, which is convenient for grinding.

[0083] In this embodiment, fluorescent marking paint is selected as the marking paint. Thus, when illuminated by the lighting lamp 34, the marking can be further seen, making the areas without marking paint more obvious.

[0084] Example 4

[0085] like Figures 1-11 As shown, based on the above embodiments, this embodiment further provides the following:

[0086] The operation method of the upper and lower mold assembly fit correction device includes the following steps:

[0087] S1. Assembly of upper mold 6:

[0088] Place the upper mold 6 inside the mold pushing assembly;

[0089] The pneumatic rod 22 drives the side hanging plate 23 to move downward until the vertical slider 233 is aligned with the upper mold 6. Then, the first locking screw 2331 is tightened to connect the vertical slider 233 with the upper mold 6 as one unit.

[0090] S2, Upper mold 6 spray coating treatment:

[0091] The tray 42 moves to the bottom of the upper mold 6, and the spray pipe 421 sprays the marking paint upward onto the upper surface of the upper mold 6. After the spraying is completed, the tray 42 returns to the top of the storage box 41.

[0092] Place the lower mold 7 inside the mold pushing assembly;

[0093] The mold lifting assembly 2 drives the upper mold 6 to move downward, so that the upper mold 6 and the lower mold 7 are assembled into one piece, and the marking paint on the upper mold surface adheres to the lower mold surface in contact with it;

[0094] This step is used to automatically spray marking paint onto the upper mold surface, and the upper and lower molds automatically cooperate;

[0095] S3. Compatibility test:

[0096] The mold lifting assembly 2 moves the upper mold 6 upward, separating the upper mold 6 from the lower mold 7.

[0097] Workers inspect the lower mold surface to determine if there are any areas on the lower mold surface without the marking paint applied.

[0098] No, if the lower surface is completely covered with the marking paint, the fit is qualified, and proceed to S5;

[0099] Yes, the lower surface is not completely covered with the marking paint, and the local fit is unqualified, so proceed to S4;

[0100] S4. Handling of substandard molds:

[0108] The pneumatic rod 22 drives the side hanging plate 23 to move upward, lifting the upper mold 6 and the lower mold 7. At the same time, the traction motor 24 drives the vertical slider 233 to move upward along the vertical slide 231, so that the upper mold 6 moves upward and separates from the lower mold 7.

[0109] Pull out the baffle 2322 and move the horizontal slider 234 along the horizontal slide groove 232 so that the lower mold 7 is misaligned to the bottom side of the upper mold 6.

[0110] Rotate the lower mold 7 so that the lower mold surface of the lower mold 7 faces downward;

[0111] The tray 42 is moved to be directly below the upper mold 6 and the lower mold 7;

[0112] The spray nozzle sprays cleaning fluid to remove the marking paint and debris from the upper and lower mold surfaces.

[0113] After cleaning, hot air is blown out from the jet pipe to dry the upper and lower molded surfaces;

[0114] The spray nozzle 421 sprays paint onto the upper surface;

[0115] After the spraying is completed, the tray 42 is returned to the storage box 41;

[0116] Rotate the lower mold 7 upwards so that the lower mold surface faces upwards, move the horizontal slider 234 to the initial position, and insert the baffle 2322;

[0117] The mold lifting assembly 2 lowers the lower mold 7 into the mold pushing assembly. Then, the traction motor 24 lowers the upper mold 6 and the lower mold 7 for reassembly. The marking paint on the upper mold surface adheres to the lower mold surface in contact with it.

[0118] S4.3, Repeat S3;

[0119] S5. Qualified mold processing:

[0123] The pneumatic rod 22 drives the side hanging plate 23 to move downward until the horizontal slider 234 is aligned with the lower mold 7. At this time, the upper mold 6 and the lower mold 7 are assembled into one piece.

[0124] Tighten the second locking screw 2342 to connect the transverse slider 234 and the lower mold 7 into one piece;

[0125] The pneumatic rod 22 drives the side hanging plate 23 to move upward, lifting the upper mold 6 and the lower mold 7. At the same time, the traction motor 24 drives the vertical slider 233 to move upward along the vertical slide 231, so that the upper mold 6 moves upward and separates from the lower mold 7.

[0126] Pull out the baffle 2322 and move the horizontal slider 234 along the horizontal slide groove 232 so that the lower mold 7 is misaligned to the bottom side of the upper mold 6.
