Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting mold technology, specifically a self-cleaning casting mold for mechanical manufacturing. Background Technology
[0002] Casting molds are commonly used molds in industrial production and construction fields for casting concrete or molten metal to manufacture parts of various shapes and sizes. Casting molds are mainly composed of upper molds, lower molds, and matching bases. By conveying molten material into the interior of the casting mold, the material cools and solidifies to obtain the required mechanical form.
[0003] The utility model with announcement number CN217414613U discloses an injection mold with a self-cleaning function. By setting a water mist nozzle on the side of the existing injection mold, and with the water mist nozzle and dust removal scraper working together, the surface of the injection mold can be automatically cleaned after each batch of injection operations, saving time and effort and eliminating the need for manual cleaning of its surface.
[0004] However, the self-cleaning molds disclosed above still have the following problems during use: Although the mold surface is cleaned by scraper and spraying mechanism, this cleaning method can only clean the upper surface of the mold. The cavity inside the mold cannot be effectively cleaned. Some material sticks to the cavity after cooling, affecting the subsequent casting work. At the same time, water mist liquid will also flow into the cavity, causing air bubbles to easily form during subsequent casting and affecting the molding effect.
[0005] Therefore, we propose a self-cleaning casting mold for mechanical manufacturing to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this invention is to provide a self-cleaning casting mold for mechanical manufacturing. This invention addresses the problem that existing methods of cleaning the mold surface using scrapers and spraying mechanisms only clean the upper surface of the mold, leaving the cavities inside the mold uncleaned. As a result, some material adheres to the cavities after cooling, affecting subsequent casting. Additionally, water mist can flow into the cavities, causing air bubbles to form during subsequent casting and affecting the molding effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning casting mold for mechanical manufacturing, comprising a support base, and a lower mold body fixedly installed at the center of the top surface of the support base, wherein an upper mold body is slidably disposed above the support base, and a lifting slide plate is fixedly disposed on the bottom surface of the lower mold body; further comprising:
[0008] The support base is provided with a cleaning mechanism on both the front and rear sides, and the cleaning mechanism includes a cleaning bracket. The bottom surface of the outer end of the cleaning bracket is provided with a guide slider through a torsion spring.
[0009] The support base is equipped with a dust collection mechanism, which includes an elastic airbag, and the inner end of the elastic airbag is fitted with an abutment plate.
[0010] Preferably, guide slide rods are fixedly provided at the four corners of the bottom surface of the support base, and the top of the guide slide rods slides through the interior of the lifting slide plate. Lifting threaded rods are rotatably provided on the left and right sides of the top surface of the support base through bearings, and the top threads of the lifting threaded rods penetrate through the left and right sides of the interior of the lifting slide plate.
[0011] Preferably, the cleaning mechanism includes a bidirectional threaded rod, which is rotatably mounted on the front and rear sides of the inner side of the support base via bearings, and the threads at both ends of the bidirectional threaded rod penetrate the interior of the guide slider.
[0012] Preferably, the cleaning mechanism includes an adsorption conduit, the inner end of which is connected to the interior of the cleaning bracket, and the outer end of which extends to the left and right sides of the interior of the support base, and the outer end of which is connected to the elastic airbag.
[0013] Preferably, the dust collection mechanism includes a transmission shaft, which is rotatably mounted on the left and right sides inside the support base via bearings, and the outer end of the transmission shaft is connected to the bottom end of the lifting threaded rods on the left and right sides via a bevel gear set.
[0014] Preferably, the outer end of the transmission shaft of the dust collection mechanism can be engaged with the outer ends of the front and rear bidirectional threaded rods through a pulley assembly, and a guide gear is fixedly provided at the inner end of the transmission shaft. Guide racks are engaged on the upper and lower sides of the guide gear, and the guide racks are slidably disposed inside the bearing base. The outer end of the guide racks is fixedly connected to the abutment pressure plate.
[0015] Preferably, the dust collection mechanism includes a dust collection scraper, which is rotatably disposed below the inner end of the symmetrically arranged cleaning brackets, and the dust collection scraper and the cleaning brackets are elastically connected to avoid obstruction between the dust collection scraper and the lower mold body when the dust collection scraper moves.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This self-cleaning casting mold for mechanical manufacturing uses a descending lifting slide to drive the upper mold body and the lower mold body to merge. Simultaneously, symmetrically distributed cleaning brackets and dust suction scrapers scrape and clean the cavity inside the lower mold body. At the same time, negative pressure absorbs any adhering material, allowing the lower mold body to merge with the upper mold body after cleaning for casting operations. The specific details are as follows:
[0017] 1. The lifting threaded rod drives the threaded lifting slide plate and the upper mold body on the bottom surface to slide downwards. At the same time, the lifting threaded rod drives the transmission shaft and the guide gear inside the bearing base to rotate through the bevel gear set. During this process, the descending lifting slide plate drives the upper mold body to descend so that the lower mold bodies can merge with each other to realize the subsequent pouring operation.
[0018] The guide gear meshes with the guide rack and moves in the opposite direction to the outer end of the contact plate, which in turn causes the elastic airbag connected to it to expand, making the adsorption duct negative pressure so that the material remaining inside the lower mold body can be cleaned through the through-connected cleaning bracket and dust suction scraper.
[0019] 2. The transmission shaft drives the meshing bidirectional threaded rod to rotate through the pulley assembly. Then, the bidirectional threaded rod drives the guide sliders connected to the threaded outer walls on the left and right sides and the cleaning bracket to slide outward synchronously. At the same time, the dust suction scraper set on the bottom surface of the cleaning bracket moves synchronously under negative pressure, thereby scraping and cleaning the material while collecting it under negative pressure to prevent it from affecting the subsequent casting of the lower mold body.
[0020] Furthermore, as the cleaning bracket drives the bottom dust suction scraper to slide outward, the dust suction scraper abuts against the side of the lower mold body, causing the dust suction scraper to rotate inward. This prevents the horizontally tilted dust suction scraper from obstructing movement between the lower mold body and the lower mold body, allowing the lower mold body to be combined with the upper mold body for casting operations after cleaning.

[0028] 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.
[0029] Please see Figures 1-6 The present invention provides the following technical solution:
[0030] Example 1: To solve the problems existing in the use of existing casting molds, this example provides a self-cleaning casting mold for mechanical manufacturing, including a support base 1 and a lower mold body 2 fixedly installed at the center of the top surface of the support base 1. An upper mold body 3 is slidably arranged above the support base 1, and a lifting slide plate 4 is fixedly arranged on the bottom surface of the lower mold body 2. Guide slide rods 9 are fixedly arranged at the four corners of the bottom surface of the support base 1, and the top of the guide slide rods 9 slides through the interior of the lifting slide plate 4. Lifting threaded rods 10 are rotatably arranged on the left and right sides of the top surface of the support base 1 through bearings, and the top threads of the lifting threaded rods 10 thread through the left and right sides of the interior of the lifting slide plate 4.
[0031] The support base 1 is equipped with a dust collection mechanism, which includes an elastic airbag 7. The inner ends of the elastic airbag 7 are fitted with abutment plates 8. The dust collection mechanism includes a drive shaft 13, which is rotatably mounted on the left and right sides of the support base 1 via bearings. The outer end of the drive shaft 13 is connected to the bottom end of the left and right lifting threaded rods 10 via a bevel gear assembly 14. The outer end of the drive shaft 13 is connected to the outer end of the front and rear bidirectional threaded rods 11 via a pulley assembly 18. The inner end of the drive shaft 13 is fixedly equipped with a guide gear 15. The upper and lower sides of the guide gear 15 are meshed with guide racks 16. The guide racks 16 are slidably mounted inside the support base 1. The outer end of the guide racks 16 is fixedly connected to the abutment plates 8.
[0032] like Figures 3-4 , Figure 6As shown, the lifting threaded rods 10 installed on the left and right sides of the support base 1 are driven to rotate by the servo motor at the top, so that the lifting threaded rods 10 drive the threaded lifting slide plate 4 to slide the upper mold body 3 on the bottom surface downward. At the same time, the lifting threaded rods 10 drive the meshing transmission shaft 13 and the guide gear 15 inside the support base 1 to rotate through the bevel gear group 14. Then, the guide gear 15 meshes with the guide racks 16 on the upper and lower sides and moves in the opposite direction to the contact pressure plate 8 at the outer end. This causes the elastic airbag 7 to expand and make the adsorption duct 12 negative pressure, so that the cleaning bracket 5 and the dust suction scraper 17 connected through it can clean the material remaining inside the lower mold body 2.
[0033] Example 2: In order to solve the problems existing in the use of existing casting molds, this example adopts the following technical solution: the front and rear sides of the support base 1 are provided with cleaning mechanisms, and the cleaning mechanism includes a cleaning bracket 5. The bottom surface of the outer end of the cleaning bracket 5 is provided with a guide slider 6 through a torsion spring. The cleaning mechanism includes a bidirectional threaded rod 11, and the bidirectional threaded rod 11 is rotatably provided on the front and rear sides inside the support base 1 through a bearing. The threads at both ends of the bidirectional threaded rod 11 pass through the inside of the guide slider 6.
[0034] The cleaning mechanism includes an adsorption conduit 12, the inner end of which is connected to the inside of the cleaning bracket 5, and the outer end of which extends to the left and right sides of the inside of the support base 1. The outer end of the adsorption conduit 12 is connected to the elastic airbag 7. The dust collection mechanism includes a dust collection scraper 17, which is rotatably disposed below the inner end of the symmetrically arranged cleaning bracket 5. The dust collection scraper 17 and the cleaning bracket 5 are elastically connected to avoid obstruction between the dust collection scraper 17 and the lower mold body 2 when the dust collection scraper 17 moves.
[0035] like Figures 2-3 , Figure 5 As shown, the transmission shaft 13 inside the support base 1 rotates through the pulley assembly 18 at the outer end, which drives the meshing bidirectional threaded rod 11 to rotate. Then, the bidirectional threaded rod 11 drives the guide sliders 6 and the cleaning bracket 5 connected to the outer walls on both sides to slide outwards in sync. At the same time, the dust suction scraper 17 set on the bottom surface of the cleaning bracket 5 moves synchronously under negative pressure, thereby scraping and cleaning the material while collecting it under negative pressure to prevent it from affecting the lower mold body 2 in subsequent casting. Furthermore, as the cleaning bracket 5 drives the dust suction scraper 17 on the bottom surface to slide outwards, the dust suction scraper 17 abuts against the side of the lower mold body 2, so that after the dust suction scraper 17 rotates inwards, it avoids the horizontally tilted dust suction scraper 17 from causing movement obstruction between it and the lower mold body 2, so that the lower mold body 2 can be combined with the upper mold body 3 for casting operation after cleaning.
[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
