Abstract

This utility model provides an auxiliary casting device for casting molds, relating to the field of casting equipment technology. Specifically, it includes two bases. One base has an L-shaped fixing seat fixedly installed on one side. Two hydraulic cylinders are mounted on the top of the L-shaped fixing seat, and both cylinders penetrate and are fixedly connected to the L-shaped fixing seat. The other base is slidably connected to the L-shaped fixing seat. Two pedestals are positioned between the two bases, and two casting mold bodies are mounted on the sides of the two pedestals that are close to each other. This application uses a servo motor output to drive a fixed rod and a cam to rotate, and a return spring to push the casting mold bodies fixed on the pedestals back to their original position, generating a periodic thrust to achieve auxiliary vibration of the mold. This vibration effectively breaks the bubble structure inside the casting liquid, causing the bubbles to escape, and simultaneously pushes the casting liquid to flow fully into the corners and gaps of the mold cavity, ensuring that the casting liquid is evenly distributed within the mold.

Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to an auxiliary casting device for casting molds. Background Technology

[0002] Casting molds play a crucial role in modern industrial production and are widely used in many fields such as automobiles, aerospace, and machinery manufacturing. They are an important tool for obtaining castings of specific shapes and sizes.

[0003] Chinese Patent Announcement No. CN210908069U discloses an auxiliary casting device for casting molds, including a base. A support plate is fixedly connected to the left side of the base, and shock-absorbing rubber is fixedly connected to the support plate. A mounting plate is fixedly connected to the right side of the base, and an electromagnetic mechanism is rotatably connected to the mounting plate. The base has a motor cavity, and a motor is fixedly connected to the motor cavity. A spur gear is fixedly connected to the output end of the motor, and a lifting mechanism is driven by the spur gear. A pulley I is fixedly connected to the output end of the motor, and a transmission mechanism is driven by the pulley I. When the sand molding machine pushes the sand mold onto the working plate, the rotation of the motor drives the pulleys I, II, and the lead screw to rotate, forcing the pressure plate and the return plate connected to the lead screw nut to press down, providing support and restraint for the sand mold and ensuring that the sand mold does not crack during the casting process.

[0004] In existing technologies, the auxiliary casting device for a casting mold only supports and restricts the sand mold by pressing down the pressure plate and the return plate. This only solves the problem of sand mold cracking and does not address the quality optimization of the casting liquid itself. It cannot eliminate air bubbles in the casting liquid, nor can it help the casting liquid fill the dead corners of the mold. This can easily lead to defects such as porosity and incomplete forming in the casting. It is particularly unsuitable for casting scenarios with complex cavities. Therefore, we have made improvements and proposed an auxiliary casting device for a casting mold. Utility Model Content

[0005] The purpose of this invention is to address the problem that current auxiliary casting devices for casting molds lack vibration defoaming and flow-aiding functions, which easily affects the quality of the casting liquid.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] An auxiliary casting device for a casting mold provides periodic auxiliary vibration to the casting mold by driving a cam to rotate via a servo motor and cooperating with a return spring. This vibration can directly act on the casting liquid, breaking the bubble structure in the liquid and reducing the porosity defects inside the casting, thereby improving the aforementioned problems.

[0008] The application is as follows:

[0009] An auxiliary casting device for a casting mold includes two bases. One base has an L-shaped fixed seat fixedly installed on one side. Two hydraulic cylinders are arranged on the top of the L-shaped fixed seat, and both hydraulic cylinders pass through the L-shaped fixed seat and are fixedly connected to it. The other base is slidably connected to the L-shaped fixed seat. Two bases are arranged between the two bases. Two casting mold bodies are arranged on the sides of the two bases that are close to each other. The two bases are respectively inserted into the interior of the two bases and are slidably connected to them. The output ends of the two hydraulic cylinders are fixedly connected to the other base. Each of the two bases is provided with a fixing structure. A T-shaped auxiliary seat is arranged between the two bases, and the corresponding sides of the T-shaped auxiliary seat are respectively inserted into the interior of the two bases and are slidably connected to them. A servo motor is fixedly installed inside the T-shaped auxiliary seat. A fixing rod is fixedly installed on the output end of the servo motor and is inserted into the interior of the T-shaped auxiliary seat and is rotatably connected to it. Several cams are fixedly installed on the outer side of the fixing rod, and the several cams are slidably connected to the two casting mold bodies.

[0010] As a preferred technical solution of this application, an electric telescopic rod is fixedly installed inside both of the bases, and the output ends of both electric telescopic rods are fixedly connected to the T-shaped auxiliary seat.

[0011] As a preferred technical solution of this application, two guide rods are fixedly installed inside each of the two bases, and the guide rods pass through the two bases and are slidably connected to them. Several return springs are fixedly installed on the side of the two bases away from the T-shaped auxiliary seat, and the ends of the several return springs away from the bases are fixedly connected to the bases.

[0012] As a preferred technical solution of this application, a partition is slidably connected to the outer side of one of the casting mold bodies, and a rubber ring and a support ring are fixedly installed on the outer side of one of the casting mold bodies, with the rubber ring being movably connected to the partition.

[0013] As a preferred technical solution of this application, the fixing structure includes a bidirectional lead screw, which is rotatably connected to the base. Two sliders are threaded onto the outer side of the bidirectional lead screw, and both sliders are rotatably connected to the base. Two L-shaped inserts are fixedly installed on the side of each slider near the casting mold body, and the L-shaped inserts pass through one side of the base and are slidably connected to it. Heat insulation sleeves are fixedly installed on the outer sides of several L-shaped inserts, and these heat insulation sleeves are inserted into the interior of the casting mold body and are slidably connected to it. A worm gear is fixedly installed at one end of the bidirectional lead screw, and a worm meshes with the outer side of the worm gear. Both the worm gear and the worm are rotatably connected to the base. A handle is fixedly installed on one side of the worm, and the handle passes through one side of the base and is rotatably connected to it. A groove is fixedly installed on the side of the base near the casting mold body, and the handle is inserted into the groove and rotatably connected to it.

[0014] As a preferred technical solution of this application, a controller is embedded in one side of one of the bases. The controller is electrically connected to a servo motor and an electric telescopic rod. A buffer pad is fixedly installed on one side of the inner wall of both bases, on the side of the base away from the return spring. Several guide rods pass through the buffer pad and are movably connected to it.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] (1) The fixed rod and cam are driven to rotate by the output end of the servo motor, and the reset spring causes the casting mold body fixed on the base to reset after being pushed, so as to generate periodic thrust to achieve auxiliary vibration of the mold. This vibration can effectively break the bubble structure inside the casting liquid, promote the escape of bubbles, and at the same time push the casting liquid to flow fully into the corner gaps of the mold cavity, ensuring that the casting liquid is evenly distributed in the mold.

[0018] (2) By inserting the T-shaped auxiliary seat into the base on both sides and sliding it, the vibration intensity can be adjusted by changing the distance between the cam and the mold. At the same time, when the fixed structure on the device needs to be replaced with different specifications of molds to produce diversified castings, the operator can quickly complete the disassembly and re-fixing of the mold without complicated tools and cumbersome operating procedures, which greatly shortens the mold replacement time.

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -2, an auxiliary casting device for a casting mold, comprising two bases 1, one base 1 having an L-shaped fixing seat 2 fixedly mounted on one side, the top of the L-shaped fixing seat 2 having two hydraulic cylinders 5, both of which penetrate the L-shaped fixing seat 2 and are fixedly connected thereto, the other base 1 being slidably connected to the L-shaped fixing seat 2, and two bases 3 being disposed between the two bases 1, with two casting mold bodies 4 disposed on the side of the two bases 3 that are close to each other, the two bases 3 being respectively inserted into the two bases 1 and slidably connected thereto, the output ends of the two hydraulic cylinders 5 being fixedly connected to the other base 1, the two bases 3 ... Each base 3 is equipped with a fixed structure. A T-shaped auxiliary base 6 is provided between the two bases 1. The corresponding sides of the T-shaped auxiliary base 6 are inserted into the interior of the two bases 1 and slidably connected thereto. A servo motor 7 is fixedly installed inside the T-shaped auxiliary base 6. A fixed rod is fixedly installed at the output end of the servo motor 7. The fixed rod is inserted into the interior of the T-shaped auxiliary base 6 and rotatably connected thereto. Several cams 8 are fixedly installed on the outside of the fixed rod. The several cams 8 are slidably connected to the two casting mold bodies 4 respectively. The casting mold body 4 located below is inserted into the casting mold body 4 located above and slidably connected thereto.

[0031] In this embodiment of the utility model, when the device is running, firstly according to the casting requirements, the two casting mold bodies 4 are respectively installed on the side of the two bases 3 that are close to each other. Since the lower casting mold body 4 can be inserted into the upper casting mold body 4 and slide, the initial docking and positioning of the mold can be achieved.

[0032] Next, the two hydraulic cylinders 5 on the top of the L-shaped fixed base 2 are activated. The output end of the hydraulic cylinder 5 generates thrust, which pushes the other base 1 that is slidably connected to the L-shaped fixed base 2 to move. The two bases 1 move closer to each other, which drives the base 3 and the casting mold body 4 to move, so that the two casting mold bodies 4 can be precisely closed.

[0033] During the casting process, if auxiliary vibration of the casting mold body 4 is required to ensure the quality of the casting, the servo motor 7 inside the T-shaped auxiliary seat 6 is activated. The output end of the servo motor 7 drives the fixed rod to rotate, and several cams 8 on the outside of the fixed rod rotate accordingly. The cams 8 slide in contact with the casting mold body 4, and the rotation of the cams 8 generates a periodic thrust on the casting mold body 4, thereby achieving auxiliary vibration of the casting mold body 4. At the same time, the fixing structure on the base 3 can firmly fix the casting mold body 4 on the base 3 to prevent the mold from shifting during the casting process.

[0034] In this embodiment of the utility model, the hydraulic cylinder 5 is used to push the base 1 to move, so as to achieve precise mold closing of the casting mold body 4. Compared with manual mold closing, it not only reduces the labor intensity of manual labor, but also greatly improves the mold closing accuracy, reduces the problem of casting scrap caused by mold closing deviation, and improves the casting qualification rate.

[0035] The servo motor 7 drives the cam 8 to rotate and provide auxiliary vibration to the casting mold body 4. This effectively eliminates air bubbles inside the casting liquid during the casting process, making the casting liquid more evenly distributed in the mold, improving the density of the castings, enhancing the mechanical properties of the castings, and extending the service life of the castings.

[0036] The fixing structure on the base 3 can firmly fix the casting mold body 4, preventing the mold from shifting due to vibration or casting liquid impact during the casting process, further ensuring the dimensional and shape accuracy of the castings, while also facilitating the installation and disassembly of the mold, improving mold replacement efficiency, and adapting to the production needs of castings of different specifications.

[0037] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -4. As a preferred embodiment of this utility model, electric telescopic rods 14 are fixedly installed inside both bases 1, and the output ends of both electric telescopic rods 14 are fixedly connected to the T-shaped auxiliary seat 6.

[0038] Two guide rods 9 are fixedly installed inside each of the two bases 1, and the guide rods 9 pass through the two bases 3 and are slidably connected to them. Several return springs 10 are fixedly installed on the side of the two bases 3 away from the T-shaped auxiliary seat 6. The ends of the return springs 10 away from the bases 3 are fixedly connected to the bases 1. Two of the return springs 10 are slidably connected to the outside of the two guide rods 9.

[0039] One of the casting mold bodies 4 has a partition plate 11 slidably connected to its outer side, and a rubber ring 12 and a support ring 13 are fixedly installed on the outer side of the casting mold body 4. The rubber ring 12 is movably connected to the partition plate 11.

[0040] The fixed structure includes a bidirectional lead screw 15, which is rotatably connected to the base 3. Two sliders 16 are threadedly connected to the outer side of the bidirectional lead screw 15, and both sliders 16 are rotatably connected to the base 3. Two L-shaped inserts 17 are fixedly installed on the side of each slider 16 near the casting mold body 4, and the L-shaped inserts 17 pass through one side of the base 3 and are slidably connected to it. Heat insulation sleeves 18 are fixedly installed on the outer side of several L-shaped inserts 17, and several heat insulation sleeves 18 are inserted into the interior of the casting mold body 4 and are slidably connected to it. A worm gear 19 is fixedly installed at one end of the bidirectional lead screw 15, and a worm 20 meshes with the outer side of the worm gear 19. Both the worm gear 19 and the worm 20 are rotatably connected to the base 3. A handle is fixedly installed on one side of the worm 20, and the handle passes through one side of the base 3 and is rotatably connected to it. A groove is fixedly installed on the side of the base 3 near the casting mold body 4, and the handle is inserted into the groove and is rotatably connected to it.

[0041] One of the bases 1 has a controller 21 embedded on one side. The controller 21 is electrically connected to the servo motor 7 and the electric telescopic rod 14. Both bases 1 have a buffer pad fixedly installed on one side of their inner walls and on the side of the base 3 away from the return spring 10. Several guide rods 9 pass through the buffer pad and are movably connected to it.

[0042] In this embodiment of the utility model, when it is necessary to adjust the position of the T-shaped auxiliary seat 6 between the two bases 1 to adapt to different specifications of the casting mold body 4 or to achieve different auxiliary vibration effects, the electric telescopic rod 14 fixedly installed inside the two bases 1 is activated. The output end of the electric telescopic rod 14 extends and retracts, driving the T-shaped auxiliary seat 6 fixedly connected to it to slide inside the base 1, thereby achieving precise adjustment of the position of the T-shaped auxiliary seat 6.

[0043] During the operation of the device, after the mold on the two bases 3 is vibrated, the return spring 10 plays a key role. The two guide rods 9 fixedly installed inside the two bases 1 pass through the two bases 3 and are slidably connected to the bases 3. They not only provide guidance for the movement of the bases 3 and ensure that the bases 3 can move smoothly in a fixed direction when they move on the top of the bases 1, but also, when the casting mold body 4 fixed on the bases 3 is subjected to auxiliary vibration, several return springs 10 fixedly installed on the side of the two bases 3 away from the T-shaped auxiliary seat 6 are compressed and stored elastic potential energy. After the mold vibration operation is completed, the return springs 10 release the elastic potential energy and push the bases 3 back to the initial position.

[0044] The top of the baffle 11 is provided with an inclined groove. When the casting liquid accidentally overflows into the predetermined casting area, the overflowing casting liquid can be guided and collected through this structure to avoid the casting liquid flowing randomly and causing material waste and equipment pollution. The rubber ring 12 fixedly installed on the outside of the casting mold body 4 is movably connected to the baffle 11, which can enhance the sealing between the baffle 11 and the casting mold body 4 and further prevent the casting liquid from leaking from the gap between the two. The support ring 13 supports the baffle 11 and ensures that the baffle 11 maintains a stable position and state during the casting process. Even if it carries the collected overflowing casting liquid, it can prevent the baffle 11 from shifting or deforming due to the impact of the casting liquid or other external forces.

[0045] When it is necessary to fix the casting mold body 4 on the base 3, rotate the handle fixedly installed on one side of the worm 20. The handle drives the worm 20 to rotate. Since the worm 20 meshes with the worm wheel 19, the worm 20 drives the worm wheel 19 to rotate. The worm wheel 19 is fixed to one end of the double-acting screw 15, which in turn drives the double-acting screw 15 to rotate on the base 3. Under the action of the rotation of the double-acting screw 15, the two sliders 16 connected to the outer thread of the double-acting screw 15 move closer or further away from each other along the axis of the double-acting screw 15. When the sliders 16 move closer to each other, the sliders 16 approach the casting mold body. Two L-shaped inserts 17, fixedly installed on one side, pass through one side of the base 3 and are inserted into the interior of the casting mold body 4 to fix the casting mold body 4. When it is necessary to disassemble the casting mold body 4, the handle is rotated in the opposite direction to make the sliders 16 move away from each other, and the L-shaped inserts 17 are pulled out from the interior of the casting mold body 4, so that the casting mold body 4 can be removed. At the same time, the heat insulation sleeve 18 fixedly installed on the outside of the L-shaped inserts 17 is inserted into the interior of the casting mold body 4, which can reduce the heat of the mold during the casting process from being transferred to the base 3 and other components through the L-shaped inserts 17, thus protecting the device components.

[0046] One of the bases 1 has a controller 21 embedded on one side that is electrically connected to the servo motor 7 and the electric telescopic rod 14. The operator can send control commands to the servo motor 7 and the electric telescopic rod 14 through the controller 21 to control the speed and direction of the servo motor 7, as well as the extension and retraction amount and speed of the electric telescopic rod 14. This allows for precise adjustment of the vibration frequency and amplitude of the cam 8 and the position of the T-shaped auxiliary seat 6. When the two bases 3 are reset under the action of the return spring 10, a buffer pad fixedly installed on one side of the inner wall of the two bases 1, away from the return spring 10, buffers the movement of the bases 3, preventing direct collision between the bases 3 and the inner wall of the base 1. Simultaneously, several guide rods 9 pass through the buffer pads and are movably connected to them, without affecting the guiding effect of the guide rods 9 on the bases 3.

[0047] In this embodiment of the utility model, the electric telescopic rod 14 drives the T-shaped auxiliary seat 6 to move. Compared with manual adjustment, the operation is more convenient and labor-saving, and it can achieve precise control of the position of the T-shaped auxiliary seat 6, ensuring that the cam 8 can always act on the optimal position of the casting mold body 4, guaranteeing the auxiliary vibration effect and further improving the quality of the castings. Furthermore, it is convenient to flexibly adjust the position of the T-shaped auxiliary seat 6 according to the height, size and other parameters of different casting mold bodies 4, so that the device can be adapted to casting molds of various specifications, greatly improving the applicability of the device and reducing the cost for enterprises to change equipment due to the production of different specifications of products.

[0048] The movement of the L-shaped insert rod 17 is achieved by using a worm gear 19 and worm 20 drive and a two-way lead screw 15 and slider 16 structure. It has a self-locking function, that is, the worm 20 can drive the worm gear 19 to rotate, but the worm gear 19 cannot drive the worm 20 to rotate. This ensures that the L-shaped insert rod 17 can maintain a stable fixed state after being inserted into the casting mold body 4, avoiding the loosening of the L-shaped insert rod 17 due to vibration or other external forces during the casting process, ensuring the reliability of the mold fixation and improving the quality of the castings. The two-way lead screw 15 drives the two sliders 16 to move synchronously, so that the L-shaped insert rod 17 can be inserted or withdrawn from both sides of the mold at the same time. This ensures that the mold is subjected to uniform force, avoids mold deformation due to unilateral force, extends the mold service life, and also makes the installation and disassembly of the mold more convenient and efficient, improving production efficiency.

[0049] The heat insulation sleeve 18 effectively blocks the transfer of heat from the mold, protecting components such as the base 3, slider 16, and L-shaped insert 17 from damage due to high temperatures, extending the overall service life of the device, reducing maintenance costs, and preventing burns to operators from high temperatures, thus improving operational safety. The handle is located in the groove of the base 3, which not only protects the handle from external impact damage but also makes the device look neater and facilitates the operator's rotation of the handle, improving operational convenience.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
