Description
Technical Field
[0001] This utility model relates to the field of mold cleaning technology, and in particular to a mold cavity cleaning device for mold processing. Background Technology
[0002] In the mold processing field, the cleanliness of the internal cavity directly affects the molding accuracy of the product, especially for automotive body panel molds, precision injection molds, and complex cavity molds. It is necessary to regularly remove residual metal shavings, mold release agent residues, and oxide scale. Currently, the industry mainly uses mechanical cleaning devices to complete this task. The core principle is to drive the cleaning head to contact the inner cavity wall through the drive mechanism, and use rotation or reciprocating motion to achieve cleaning.
[0003] Traditional cleaning heads are mostly fixed structures, which cannot adapt to irregularly shaped cavities. This not only leaves residue but may also scratch the mold surface. To improve fit, this not only leads to a decrease in the quality of injection molded products but also damages the mold surface, increasing production costs. Some existing technologies use elastic support structures, which allow the brush head to adapt to simple curved surfaces through elastic deformation. Other technologies allow manual adjustment of the brush head angle to adapt to the sidewalls of cavities with specific angles. However, in actual use, elastic support structures can only achieve unidirectional extension and contraction and cannot cope with complex cavities with multiple tilts. Manual adjustment requires stopping the machine and cannot adapt to changes in the wall surface during dynamic cleaning. Utility Model Content

The middle part of the bottom wall of the driven gear is fixedly connected to the top of the conical brush head.
[0012] As a further description of the above technical solution:
[0013] The displacement mechanism includes a sliding plate, which is slidably connected to the top of the housing shell.

[0014] As a further description of the above technical solution:
[0015] The drive assembly includes a second motor, which is installed on the rear side of the outer wall of the housing. The output end of the second motor is fixedly connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to the middle of the sliding plate.
[0016] As a further description of the above technical solution:

When the sliding plate moves to the edge of the outer shell of the box, it contacts the buffer cylinder. The buffer cylinder absorbs vibration and prevents structural damage. This mechanism can flexibly change the position of the cleaning mechanism to improve the cleaning effect. Attached Figure Description

[0030] 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.
[0031] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a mold cavity cleaning device for mold processing, comprising a housing 1, a cleaning mechanism 2 installed inside the housing 1, the cleaning mechanism 2 being used to clean the mold cavity, and a displacement mechanism 3 installed on the top of the cleaning mechanism 2, the displacement mechanism 3 being used to move the cleaning mechanism 2.
[0032] The cleaning mechanism 2 includes a mounting base plate 201, which is disposed inside the housing shell 1. A telescopic component 202 is rotatably connected to the middle of the bottom wall of the mounting base plate 201. A swing component 205 is installed on the right side of the bottom arm of the mounting base plate 201. A gear disk 206 is provided at the bottom of the housing shell 1. A conical brush head 207 is rotatably connected to the bottom of the gear disk 206. A power component 204 is installed on the right side of the top arm of the gear disk 206.
[0033] The telescopic assembly 202 includes a first sleeve 2021, which is rotatably connected to the middle of the bottom wall of the mounting base plate 201. A second sleeve 2022 is slidably connected to the inner wall of the first sleeve 2021. A connecting rod 2023 is slidably connected to the bottom end of the bottom wall of the second sleeve 2022. Compression springs 2024 are fixedly connected to the top ends of both the second sleeve 2022 and the connecting rod 2023. Two return springs 203 are fixedly connected to the left side of the top arm of the first sleeve 2021.
[0034] The swing assembly 205 includes a motor 2051, which is located on the right side of the bottom wall of the mounting base plate 201. An eccentric wheel 2052 is fixedly connected to the output end of the motor 2051. A connecting rod 2053 is located on the left side of the eccentric wheel 2052. The right end of the connecting rod 2053 is fixedly connected to the top of the outer wall of the sleeve 2021.
[0035] The power assembly 204 includes a motor 2041, which is mounted on the right side of the top wall of the gear disk 206. The output end of the motor 2041 is fixedly connected to a drive gear 2042, and a driven gear 2043 is meshed with the left side of the drive gear 2042. The middle part of the bottom wall of the driven gear 2043 is fixedly connected to the top of the conical brush head 207.
[0036] Specifically, after the motor 2041 starts working, its output shaft rotates, driving the drive gear 2042 to rotate. The drive gear 2042 meshes with the driven gear 2043, causing the driven gear 2043 to rotate synchronously within the gear disk 206, transmitting power. The output shaft of the driven gear 2043 connects to the conical brush head 207, driving the conical brush head 207 to rotate at high speed for cleaning. One end of the connecting rod 2023 is nested inside the sleeve 2022, and the other end of the sleeve 2022 is nested inside the sleeve 1021, forming a telescopic structure. A compression spring 2024 is installed in the cavity formed by the three components. The two ends of the compression spring 2024 are connected to the connecting rod 2023 and the sleeve 1021 respectively, so that the telescopic component 202 can automatically extend and retract according to the change of the mold cavity height, adaptively adjusting the working height to adapt to the varied shape of the mold cavity. When the brush head 207 reaches the curved surface and a gap appears between it and the curved surface, preventing it from fully adhering, motor 2051 is started. The output shaft of motor 2051 drives eccentric wheel 2052 to rotate around its axis. The edge of eccentric wheel 2052 is connected to one end of connecting rod 2053 via a pin, and the other end of connecting rod 2053 is connected to sleeve 2021. The rotation of eccentric wheel 2052 causes connecting rod 2053 to move backward in the horizontal direction, pushing sleeve 2021 to swing left and right around the connection point. At the same time, the return spring 203 is compressed, causing the elastic force generated by the compression return spring 203 to laterally compress the conical brush head 207, making it tightly adhere to the inner surface of the mold. When motor 2051 stops working, the return spring 203 rebounds under its own elastic force, causing sleeve 2021 to reset and prompting telescopic component 202 to return to its original working angle.
[0037] Reference Figure 2 and Figure 5The displacement mechanism 3 includes a sliding plate 301, which is slidably connected to the top of the housing 1. The bottom wall of the sliding plate 301 is slidably connected to the top wall of the mounting base plate 201. A hydraulic push rod 303 is fixedly connected to the left side of the bottom wall of the sliding plate 301. Two buffer cylinders 304 are provided at the front and rear of the sliding plate 301. Baffles 305 are fixedly connected to the front and rear sides of the housing 1. Multiple buffer cylinders 304 are fixedly connected to the left and right sides of the outer wall of the baffles 305. A drive assembly 302 is installed on the rear side of the sliding plate 301.
[0038] The drive assembly 302 includes a second motor 3021, which is installed on the rear side of the outer wall of the housing 1. The output end of the second motor 3021 is fixedly connected to a threaded rod 3022, and the outer wall of the threaded rod 3022 is threadedly connected to the middle part of the sliding plate 301.
[0039] Specifically, after the second motor 3021 is powered on, its output shaft rotates, causing the threaded rod 3022 to rotate synchronously in the baffle 305. Because both ends of the threaded rod 3022 pass through the baffle 305 and its position is fixed by the baffle 305, as the output shaft of the second motor 3021 continues to rotate, the threaded hole at the bottom of the sliding plate 301 engages with the threaded rod 3022 and begins to move horizontally along the axial direction on the outer wall of the threaded rod 3022. The top of the sliding plate 301 is connected to the bottom of the cleaning mechanism 2, thereby adjusting the front and rear position of the cleaning mechanism 2. The hydraulic push rod 303 is activated, and the piston rod of the hydraulic push rod 303 extends to push the mounting base plate 201 to slide left and right on the slide rail at the bottom of the sliding plate 301. The mounting base plate 201 is connected to the cleaning mechanism 2, thereby adjusting the left and right position of the cleaning mechanism 2. When the sliding plate 301 is moved to the front and rear edges of the housing 1 under the drive of the threaded rod 3022, its side contacts the end of the buffer cylinder 304 to absorb the vibration during the collision process and prevent frequent vibration from causing structural damage to the connecting parts.
[0040] Reference Figure 3 and Figure 5 The top wall of the mounting base plate 201 is fixedly connected with two dovetail tenons 4, the bottom wall of the sliding plate 301 is provided with two dovetail grooves 6, and the two dovetail tenons 4 are slidably connected to the inner wall of the two dovetail grooves 6. The outer wall of the baffle 305 is fixedly connected with a motor support plate 5, and the right side of the bottom wall of the mounting base plate 201 is fixedly connected with a wheel frame 7.
[0041] Specifically, the dovetail tenon 4 and the dovetail groove 6 engage with each other, allowing the mounting base plate 201 to slide linearly and smoothly on the sliding plate 301, the eccentric wheel 2052 to rotate in the wheel frame 7, and the motor support plate 5 to fix the motor 2021 on the baffle 305.
[0042] Working principle: After motor 1 2041 starts working, it drives the driving gear 2042 and driven gear 2043 to rotate within the gear disk 206, transmitting power and driving the conical brush head 207 to rotate for cleaning. The connecting rod 2023 is nested in the sleeve 2022, which in turn is nested in the sleeve 1 2021. A compression spring 2024 is provided in the cavity, allowing the telescopic component 202 to adaptively adjust the working height according to the change in the height of the mold cavity, adapting to various shapes. When cleaning reaches the curved surface, where the conical brush head 207 cannot fully fit, motor 1 2051 is started, driving the eccentric wheel 2052 to rotate. The eccentric wheel 2052 is connected to the connecting rod 2053 and... Sleeve 1 2021 is connected, and the rotation of eccentric wheel 2052 causes connecting rod 2053 to move horizontally, pushing sleeve 1 2021 to start swinging. At the same time, compression return spring 203 squeezes the conical brush head 207 laterally so that it fits tightly against the inner surface of the mold. When motor 1 2051 stops working, return spring 203 rebounds under the action of elasticity, causing telescopic component 202 to return to its original working angle. This mechanism can automatically adjust the cleaning angle and fitting force according to the changing shape of the inner cavity of the mold, solving the problem that the existing technology can only achieve unidirectional telescopic, cannot cope with complex inner cavities with multiple tilts, requires machine stop operation, and cannot adapt to wall changes during dynamic cleaning in real time.
[0043] After the second motor 3021 starts working, it drives the threaded rod 3022 to rotate in the baffle 305. Because the horizontal position of the threaded rod 3022 is fixed by the baffle 305, as the second motor 3021 rotates, the sliding plate 301 begins to move horizontally on the outer wall of the threaded rod 3022, thereby adjusting the front and rear position of the cleaning mechanism 2. The hydraulic push rod 303 is activated, and the hydraulic push rod 303 pushes the mounting base plate 201 to slide left and right at the bottom of the sliding plate 301, thereby adjusting the left and right position of the cleaning mechanism 2. When the sliding plate 301 moves to the front and rear edges of the housing 1, it contacts the buffer cylinder 304. The buffer cylinder 304 absorbs the vibration during the collision process and prevents frequent vibration from causing structural damage. This mechanism can flexibly change the position of the cleaning mechanism 2 and improve the cleaning effect.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
