Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically an adjustable-depth three-dimensional carving mold. Background Technology

[0002] 3D engraving molds are a type of mold that uses 3D modeling technology as its core and combines it with digital manufacturing processes. They are widely used in industrial manufacturing, handicrafts, architectural models, and other fields. Their core feature lies in the precise replication of complex three-dimensional structures through precision engraving equipment and software.

[0003] Currently, stamping dies are generally required to have good rigidity and stamping strength to ensure that they are not prone to cracking or deformation during long-term repeated stamping operations. However, existing dies have obvious limitations—their structural design is usually only designed for stamping workpieces of a single thickness, lacking an adjustable and adaptable structure. They cannot achieve compatible processing of workpieces of different thicknesses through parameter adjustments, which directly leads to problems such as limited applicability and insufficient production flexibility.

[0004] Therefore, this invention provides a three-dimensional carving mold with adjustable depth to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This invention provides an adjustable-depth three-dimensional carving mold, aiming to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a lower mold and an upper mold. A forming plate is provided inside the cavity of the lower mold. An adjustment mechanism is symmetrically provided between the forming plate and the lower mold. The adjustment mechanism includes a lead screw, two moving blocks, and a support plate. The lead screw is rotatably connected inside the lower mold, and the two moving blocks are slidably connected inside the lower mold. Both moving blocks are threadedly connected to the lead screw. A mounting platform is fixedly connected to each moving block, and one end of the support plate is fixedly connected to the mounting platform.

[0009] As a preferred technical solution of this application, mounting blocks are symmetrically fixed to the bottom of the molding plate, and guide rods are fixedly connected between the two mounting blocks. Two sliders are connected to the guide rods, and the guide rods slide through the sliders. The sliders are slidably connected to the molding plate.

[0010] As a preferred technical solution of this application, a connecting block is provided between the two mounting blocks, and the connecting block is fixedly connected to the molding plate. The guide rod passes through the connecting block, and two springs are sleeved on the guide rod. The two ends of the springs are fixedly connected to the connecting block and the slider, respectively.

[0011] As a preferred technical solution of this application, the bottom of the slider is fixedly connected to a connecting platform, and the other end of the support plate is rotatably connected to the connecting platform.

[0012] As a preferred technical solution of this application, a pulley is coaxially fixed on the upper part of the lead screw, and a transmission belt is connected between the two pulleys.

[0013] As a preferred technical solution of this application, a handle is rotatably connected to the side wall of the lower mold, and the handle is fixed coaxially with the lead screw.

[0014] (III) Beneficial Effects

[0015] The position of the forming plate is adjusted by setting an adjustment mechanism. By turning the handle, the two adjustment mechanisms are driven by the pulley and the transmission belt, causing the support plate in the adjustment mechanism to rotate. When the support plate gradually approaches a vertical state, the cavity depth of the lower mold decreases. When the support plate gradually approaches a horizontal state, the cavity depth of the lower mold increases. This adjusts the cavity depth of the lower mold to accommodate the requirements of processing workpieces of different thicknesses. Attached Figure Description

[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 utility model provides an adjustable-depth three-dimensional carving mold, such as... Figures 1-4 As shown, the technical solution includes a lower mold 1 and an upper mold 2. A forming plate 4 is provided inside the cavity of the lower mold 1. An adjustment mechanism is symmetrically provided between the forming plate 4 and the lower mold 1. The adjustment mechanism includes a lead screw 10, two moving blocks 11, and a support plate 13. The lead screw 10 is rotatably connected inside the lower mold 1, and the two moving blocks 11 are slidably connected inside the lower mold 1. Both moving blocks 11 are threadedly connected to the lead screw 10. A mounting platform 12 is fixedly connected to the moving blocks 11, and one end of the support plate 13 is fixedly connected to the mounting platform 12. The position of the forming plate 4 is adjusted by setting the adjustment mechanism. When the adjustment mechanism operates, it drives the support plate 13 in the adjustment mechanism to rotate. When the support plate 13 gradually tends to a vertical state, the cavity depth of the lower mold 1 decreases. When the support plate 13 gradually tends to a horizontal state, the cavity depth of the lower mold 1 increases. This adjusts the cavity depth of the lower mold 1 to accommodate the requirements of processing workpieces of different thicknesses.

[0024] Mounting blocks 5 are symmetrically fixed to the bottom of the molding plate 4. A guide rod 6 is fixedly connected between the two mounting blocks 5. Two sliders 7 are connected to the guide rod 6, and the guide rod 6 slides through the sliders 7. The sliders 7 are slidably connected to the molding plate 4. A connecting block is provided between the two mounting blocks 5, and the connecting block is fixedly connected to the molding plate 4. The guide rod 6 passes through the connecting block. Two springs 8 are sleeved on the guide rod 6. The two ends of the springs 8 are fixedly connected to the connecting block and the sliders 7 respectively. By setting the springs 8, the stability of the sliders 7 is improved, so that the sliders 7 are always symmetrically positioned at the bottom of the molding plate 4.

[0025] When in use, as the support plate 13 in the adjustment mechanism gradually approaches a vertical state, the support plate 13 drives the slider 7 to compress the spring 8. When the support plate 13 gradually approaches a horizontal state, the support plate 13 drives the slider 7 to stretch the spring 8.

[0026] The bottom of the slider 7 is fixedly connected to the connecting platform 9, the other end of the support plate 13 is rotatably connected to the connecting platform 9, the upper part of the lead screw 10 is coaxially fixed to the pulley 14, the two pulleys 14 are connected by a transmission belt 15, and the side wall of the lower mold 1 is rotatably connected to the handle 3, which is coaxially fixed to the lead screw 10.

[0027] In use, rotating the handle 3 drives the coaxially fixed lead screw 10 and pulley 14 to rotate. The rotating pulley 14 drives another pulley 14 to rotate synchronously through the transmission belt 15, which in turn drives the other lead screw 10 to rotate. Rotating the lead screw 10 drives the two moving blocks 11 to move in opposite directions. When the two moving blocks 11 approach each other, the moving blocks 11 drive the support plate 13 to gradually tend to a vertical state. At this time, the cavity depth of the lower mold 1 decreases. When the two moving blocks 11 move away from each other, the moving blocks 11 drive the support plate 13 to gradually tend to a horizontal state. At this time, the cavity depth of the lower mold 1 increases, thus achieving the effect of adjusting the cavity depth of the lower mold 1.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
