Description

Technical Field

[0001] This utility model belongs to the field of mold manufacturing technology, and specifically relates to a scraping device for mold manufacturing. Background Technology

[0002] A mold typically consists of multiple components, including a front mold, a rear mold, a mold blank, and special functional components. Among these, the hot runner system is a crucial component, preventing the plastic from solidifying within the mold. Molds can be categorized by design into soft molds and hard molds. Soft molds have a shorter lifespan and are typically experimental designs used to test the feasibility of product designs. Hard molds, on the other hand, are primarily designed for commercially viable products and have a longer lifespan. Furthermore, molds can be classified by structure as two-plate molds and three-plate molds. After mold production, surface scraping is necessary to ensure the final product's aesthetic appeal. However, current mold scraping methods involve mounting the mold on a fixture and then scraping one side using a polishing wheel. This method is inefficient, and after scraping one side, the mold must be removed from the fixture, the scraped surface replaced, and the scraping process repeated, which cannot meet production requirements. Therefore, the inventor proposes a mold scraping device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a scraping device for mold production, which aims to solve the problems of low work efficiency caused by using a polishing wheel for single-sided scraping, and the need to remove the mold from the fixture and replace the scraping surface after single-sided scraping is completed.

[0005] (2) Technical solution

[0006] To address the aforementioned technical problems, this utility model provides a mold-making scraping device, comprising a support platform, a fixing mechanism, a movable frame, and a carrier plate. The carrier plate is rotatably mounted on the upper surface of the support platform. A motor connected to the carrier plate is located inside the support platform. A crossbeam is mounted on the upper surface of the support platform, and the fixing mechanism is mounted on the crossbeam, positioned above and spaced apart from the carrier plate. Two sets of opposing drive boxes are located on the upper surface of the support platform, slidably connected to the support platform. A movable frame is located on the surface of the drive boxes facing the carrier plate. A scraper wheel is vertically rotatably mounted on the movable frame facing the carrier plate. A rotary motor is fixedly mounted on the upper surface of the movable frame, connected to the scraper wheel. Thanks to the carrier plate and mounting plate, molds requiring scraping can be quickly clamped. Furthermore, due to its rotatability, after scraping both sides of the mold, the scraped surface can be adjusted by rotation, improving mold processing efficiency.

[0022] 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.

[0023] This specific embodiment is a scraping device for mold production, and its structural schematic diagram is shown below. Figure 1 As shown, it includes a support platform 1, a fixing mechanism 5, a movable frame 3, and a bearing plate 2. The bearing plate 2 is rotatably mounted on the upper surface of the support platform 1. The inside of the support platform 1 is equipped with a motor that connects to the bearing plate 2. A crossbeam is mounted on the upper surface of the support platform 1. The fixing mechanism 5 is mounted on the crossbeam. The fixing mechanism 5 is located above the bearing plate 2 and is spaced apart from the bearing plate 2.

[0024] The upper surface of the support platform 1 is provided with two sets of oppositely distributed drive boxes 4. The drive boxes 4 are slidably connected to the support platform 1, and the surface of the drive boxes 4 facing the bearing plate 2 is provided with a movable frame 3.

[0025] Reference Figure 3 The fixing mechanism 5 includes a fixing column 9, a lifting rod 11, and a mounting plate 13. The fixing column 9 is vertically arranged and fixedly connected to the crossbeam. A drive motor 10 is installed above the fixing column 9. The lifting rod 11 slides into the bottom of the fixing column 9. An internal screw 12 is vertically rotatably installed inside the fixing column 9. The internal screw 12 is threadedly connected to the lifting rod 11. The drive motor 10 is connected to the internal screw 12. The mounting plate 13 is rotatably installed at the bottom of the lifting rod 11. A connecting block 15 is fixedly connected to the bottom of the drive box 4. A horizontal moving groove for the connecting block 15 to slide is opened on the upper surface of the support platform 1. A telescopic cylinder 16 is horizontally installed in the moving groove. The telescopic end of the telescopic cylinder 16 is fixedly connected to the connecting block 15.

[0026] Reference Figure 2 , Figure 4 A scraper 8 is vertically rotatably mounted on the surface of the movable frame 3 facing the support plate 2. A rotary motor 7 is fixedly mounted on the upper surface of the movable frame 3, and the rotary motor 7 is connected to the scraper 8. A movable block 6 protrudes from the surface of the movable frame 3 facing the drive box 4, and a horizontal sliding groove is formed on the side wall of the drive box 4. The movable block 6 is slidably mounted in the sliding groove, and a drive screw is provided in the sliding groove. A stepper motor 14 connected to the inner screw 12 is mounted on the outer wall of the drive box 4, and the movable block 6 is threadedly connected to the drive screw.

[0027] Working principle: In use, the mold to be scraped is first placed on the upper surface of the support plate 2. Then, the drive motor 10 starts and drives the inner screw 12 to rotate. The lifting rod 11, which is threaded to the inner screw 12, moves downward under force, causing the mounting plate 13 at the bottom to contact the mold. At this time, the mold is fixed and clamped. Then, the telescopic cylinder 16 starts and extends, causing the connecting block 15 to slide along the moving groove, thereby driving the drive box 4 to move closer to the mold until the scraper 8 is in contact with the mold. The rotary motor 7 starts and adjusts the scraper 8 to rotate. The scraper 8 contacts the surface of the mold for scraping. Then, the stepper motor... When the machine 14 starts, it drives the drive screw to rotate, which in turn causes the moving block 6 to slide under force and move horizontally along the drive box 4. The scraper 8 can then move laterally along the mold, which allows for better scraping of the mold and a wider scraping range. After both sides of the mold are scraped, the telescopic cylinder 16 retracts, causing the drive box 4 to gradually move away from the mold. At this time, the bearing plate 2 (driven by a motor, not shown in the figure) rotates, and the mounting plate 13 rotates synchronously to adjust the contact surface between the mold and the scraper 8. Then the drive box 4 moves closer to the mold again for scraping. This eliminates the need for multiple mold disassembly and assembly, resulting in higher efficiency in mold scraping.

[0028] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
