Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically a casting mold with an adjustment mechanism. Background Technology

[0002] A casting mold is a tool used to create a part's structural shape in advance using other easily formable materials. This mold is then placed inside a sand mold, creating a cavity with dimensions identical to the part's structure. A fluid is poured into this cavity, and after cooling and solidifying, a part with the exact same shape and structure as the mold is formed. Casting molds are a crucial part of the casting process. However, because molds cannot be adaptively adjusted to accommodate actual height deviations in the sand mold, even slight height errors during manufacturing or placement can significantly reduce the fit between the mold and the sand mold, easily leading to gaps at the top or bottom of the cavity. From a left-right adjustment perspective, the fixed position design of the mold is insufficient to handle horizontal deviations in the sand mold. In mass production, the positioning accuracy of the sand mold inevitably fluctuates, and the mold cannot compensate for these deviations through left-right adjustments. This results in excessive tolerances in key geometric dimensions such as cavity symmetry and coaxiality. Utility Model Content

[0003] The purpose of this invention is to provide a casting mold with an adjustment mechanism, which has the advantage of automatic adjustment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a casting mold with an adjustment mechanism, comprising a base, on both sides of the bottom of the base, a first motor fixedly mounted, a second gear fixedly mounted at the output end of the first motor, the first gear meshing with the front surface of the second gear, a first threaded rod fixedly mounted on the inner surface of the first gear, a first threaded sleeve threadedly mounted on the front surface of the first threaded rod, an adjustment box fixedly mounted at one end of the first threaded sleeves close to each other via a bracket, a second motor fixedly mounted at the left end of the inner cavity of the adjustment box, a second threaded rod fixedly mounted at the output end of the second motor, a second threaded sleeve threadedly mounted on the front surface of the second threaded rod, a support frame fixedly mounted at the top of the second threaded sleeve via a bracket, and a mold box provided at the top of the support frame.

[0005] As a preferred embodiment, support columns are fixedly installed around the bottom of the base, and anti-slip sleeves are fixedly installed at the bottom of the support columns.

[0006] As a preferred embodiment, control boxes are fixedly installed on both sides of the top of the base, and a display screen is provided on the upper part of the front surface of the control box.

[0007] As a preferred embodiment, limit rods are fixedly installed on both sides of the top of the base, and the inner surface of the first threaded sleeve is slidably installed on the front surface of the limit rod.

[0008] As a preferred embodiment, the regulating box has doors movably installed on both sides of its front surface, and handles are fixedly installed on the ends of the front surfaces of the doors that are close to each other.

[0009] As a preferred embodiment, electric telescopic rods are fixedly installed on both sides of the outer surface of the support frame via brackets, and clamping plates are fixedly installed on the output ends of the electric telescopic rods. The clamping plates are clamped to both sides of the mold box at their close ends.

[0010] As a preferred embodiment, a guide rail is fixedly installed at the bottom of the inner cavity of the regulating box, a slide rod is slidably installed in the inner cavity of the guide rail, and the top of the slide rod is fixedly installed at the bottom of the second threaded sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a first motor on each side of the base to drive a second gear to rotate. The meshing of the second and first gears drives the first threaded rod to rotate, causing the first threaded sleeve to move axially along the first threaded rod. This, in turn, allows for precise height adjustment via a support and adjustment box. This structure effectively solves the problem of traditional molds being unable to adapt to sand mold height deviations due to their fixed height. It significantly improves the fit between the mold and the sand mold, avoids the risk of liquid metal leakage and sand mold collapse during pouring, and reduces the scrap rate. The second motor inside the adjustment box drives the second threaded rod to rotate, causing the second threaded sleeve to move laterally along the second threaded rod. This, in turn, allows for left-right adjustment via a support frame and the top mold box. This adjustment method can compensate for horizontal positioning deviations in the sand mold in real time, ensuring that key geometric tolerances such as symmetry and coaxiality of the cavity meet design requirements. It is particularly suitable for casting parts with precision structures such as holes and bosses, reducing subsequent machining and correction processes and lowering production costs.

[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0016] Example 1 Please see Figures 1-3 As shown, this utility model provides a casting mold with an adjustment mechanism, including a base 1. A first motor 16 is fixedly installed on both sides of the bottom of the base 1. A second gear 15 is fixedly installed at the output end of the first motor 16. A first gear 2 is meshed on the front surface of the second gear 15. A first threaded rod 10 is fixedly installed on the inner surface of the first gear 2. A first threaded sleeve 11 is threaded on the front surface of the first threaded rod 10. An adjustment box 9 is fixedly installed at one end of the first threaded sleeve 11 that is close to each other through a bracket. A second motor 17 is fixedly installed at the left end of the inner cavity of the adjustment box 9. A second threaded rod 19 is fixedly installed at the output end of the second motor 17. A second threaded sleeve 18 is threaded on the front surface of the second threaded rod 19. A support frame 13 is fixedly installed on the top of the second threaded sleeve 18 through a bracket. A mold box 6 is provided on the top of the support frame 13.

[0017] This technical solution uses a first motor 16 on both sides of the bottom of the base 1 to drive the second gear 15 to rotate. The meshing transmission between the second gear 15 and the first gear 2 drives the first threaded rod 10 to rotate, causing the first threaded sleeve 11 to move axially along the first threaded rod 10. This, in turn, drives the adjustment box 9 through the bracket to achieve precise height adjustment. This structure effectively solves the problem that traditional molds cannot adapt to sand mold height deviations due to fixed height. It significantly improves the fit between the mold and the sand mold, avoids the risk of liquid metal leakage and sand mold collapse during pouring, and reduces the scrap rate. The second motor 17 inside the adjustment box 9 drives the second threaded rod 19 to rotate, causing the second threaded sleeve 18 to move laterally along the second threaded rod 19. This, through the bracket, drives the support frame 13 and the mold box 6 on top to complete the left and right adjustment. This adjustment method can compensate for the positioning deviation of the sand mold in the horizontal direction in real time, ensuring that the symmetry, coaxiality and other key geometric tolerances of the cavity meet the design requirements. It is especially suitable for casting parts with precision structures such as hole systems and bosses, reducing subsequent processing and correction steps and lowering production costs.

[0018] Example 2 Based on Embodiment 1, this utility model is as follows: Figure 1 As shown, support columns are fixedly installed around the bottom of the base 1, and anti-slip sleeves are fixedly installed at the bottom of the support columns. Control boxes 3 are fixedly installed on both sides of the top of the base 1, and a display screen is provided on the upper part of the front surface of the control box 3.

[0019] By adopting the above technical solution, the support column and anti-slip sleeve are set to achieve the effect of supporting the whole, the limit rod 12 is set to limit the first threaded sleeve 11, and the control box 3 is set to facilitate the user to operate the device.

[0020] Example 3 This utility model is as follows Figures 2-3 As shown, limit rods 12 are fixedly installed on both sides of the top of the base 1. The inner surface of the first threaded sleeve 11 is slidably installed on the front surface of the limit rod 12. Box doors 5 are movably installed on both sides of the front surface of the adjustment box 9. Handles 4 are fixedly installed on the near ends of the front surfaces of the box doors 5. Electric telescopic rods 8 are fixedly installed on both sides of the outer surface of the support frame 13 through brackets. Clamping plates 7 are fixedly installed on the output end of the electric telescopic rods 8. Clamping plates 7 are clamped on both sides of the near ends of the clamping plates 7. Guide rails 14 are fixedly installed at the bottom of the inner cavity of the adjustment box 9. Sliding rods are slidably installed in the inner cavity of the guide rails 14, and the top of the sliding rods is fixedly installed on the bottom of the second threaded sleeve 18.

[0021] By adopting the above technical solution, the setting of the box door 5 and the handle 4 facilitates the user to carry out daily maintenance of the adjustment box 9. The setting of the electric telescopic rod 8 and the clamping plate 7 achieves the effect of clamping and limiting the mold box 6. The setting of the guide rail 14 and the slide rod achieves the effect of guiding the second threaded sleeve 18.

[0022] The working principle of this utility model is as follows: After the first motor 16 on both sides of the bottom of the base 1 is started as a power source, its output end drives the second gear 15 to rotate. Since the second gear 15 is meshed with the first gear 2, the rotational motion of the second gear 15 is transmitted to the first gear 2 through gear meshing, so that the first gear 2 rotates synchronously with the second gear 15. Since the first gear 2 is fixedly installed on the inner surface of the first threaded rod 10, the rotation of the first gear 2 directly drives the first threaded rod 10 to rotate. The first threaded sleeve 11, which is threaded on the front surface of the first threaded rod 10, moves linearly along the axial direction of the first threaded rod 10 under the action of thread transmission. The ends of the first threaded sleeves 11 that are close to each other are connected to the bracket and the adjustment Since the section box 9 is fixedly connected, the linear movement of the first threaded sleeve 11 drives the adjustment box 9 to achieve the upward or downward adjustment in the height direction. During the left and right adjustment process, after the second motor 17 at the left end of the inner cavity of the adjustment box 9 is started, its output end drives the second threaded rod 19 to rotate. The second threaded sleeve 18, which is threaded on the positive surface of the second threaded rod 19, moves laterally in a straight line along the axial direction of the second threaded rod 19 under the action of thread transmission. The top of the second threaded sleeve 18 is fixedly connected to the support frame 13 through the bracket, and the mold box 6 is set on the top of the support frame 13. Therefore, the lateral movement of the second threaded sleeve 18 is transmitted to the mold box 6 through the bracket and the support frame 13, and finally realizes the translational adjustment of the mold box 6 in the left and right directions.
