Description

Technical Field

[0001] This invention relates to the field of mold processing and forming technology, specifically to a cutting and forming device for wax mold casting. Background Technology

[0002] Wax casting molds are specialized tools used to create wax models, playing a crucial role in the investment casting process. Their core function is to press or inject molten wax into the mold cavity, forming a wax model that conforms to the final metal part after cooling. Due to current part processing requirements, the molds need to undergo stamping operations to produce the shapes of different parts of the part. However, existing mold stamping devices still have some problems, specifically as follows: Existing stamping devices all use hydraulic rods to drive the punch downwards to stamp the raw material sheet used for mold production into different shapes. However, the method used is to directly use the punch head to complete the stamping of the raw material in one go. This can easily cause over-stamping of the raw material sheet, resulting in cracks or even breakage at the stamping deformation point. In addition, in order to reduce the friction between the punch and the material and protect the surface finish and integrity of the material, the existing stamping process uses the method of applying lubricating oil. However, the punch of the existing stamping device cannot be replenished with lubricating oil in time, which requires manual replenishment after a period of use, thereby reducing the production efficiency of the entire stamping device. To address this issue, we propose a wax mold casting mold cutting and forming device. Summary of the Invention

[0011] In a preferred embodiment, the central block consists of a central disk and three equally spaced extended rods on the disk, one of which is vertically upward. The second suspension end is movably engaged with the plug rod. There are two first rotating wheels, which are rotatably installed at the lower ends of the central block. The first gear meshes with the drive rack.

The sponge block allows for the application of lubricating oil to the surface of the structure that rotates to the top after each rotation and change of the stamping component. This ensures that the surface of the component has sufficient lubricating oil when it rotates to the bottom next time. As a result, the device can maintain sufficient lubrication between the device and the raw material surface during each stamping process, avoiding damage to the raw material surface during stamping and ensuring the forming quality of the mold.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The wax mold casting mold cutting and forming apparatus involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-5A wax mold casting mold cutting and forming device includes a base plate 1, side frames 2 are fixedly installed on both sides of the base plate 1, an electric hydraulic rod 3 is fixedly installed on the side frame 2, a pressing component 4 is fixedly connected to the bottom end of the electric hydraulic rod 3, a second elastic telescopic rod 5 is fixedly installed on both sides of the base plate 1 through a protruding plate, a cross frame 6 is fixedly installed at the top end of the second elastic telescopic rod 5, a side plate 7 is fixedly installed at the end of the cross frame 6, an adjustment drive component 9 is movably installed on one side of the side plate 7, a pulling adjustment component 8 is fixedly installed on the side of the adjustment drive component 9, a stamping component 10 is movably connected to the side plate 7, a plug-in rod 11 is fixedly installed on one side of the side plate 7, and a limit component 12 is fixedly installed at one end of the side plate 7. Compared with the prior art, this application has two parts: a first punch 102 and a second punch 103. The stamping end of the second punch 103 has a rounded edge. The stamping assembly 10 can rotate around the bottom of the side plate 7. In this way, the up and down movement during the stamping process automatically drives the stamping assembly 10 to rotate intermittently, with each rotation being half a circle. This automatically ensures that each upward movement of the stamping structure causes the stamping assembly 10 to automatically flip. The flipping causes the first punch 102 and the second punch 103 to alternate, thus dividing the entire stamping process into two stages: after the second punch 103 initially stamps, the flipping action causes the first punch 102 to rotate. 102 rotates to the bottom for a second stamping operation to complete the stamping process. This prevents the raw material plate from being over-stamped in one go, ensuring the integrity of the raw material plate. At the same time, a lubricating oil storage chamber is set inside the central pressure groove 46. A sponge block is set at the bottom of the chamber. The sponge block can be used to apply lubricating oil to the surface of the structure that rotates to the top after each rotation and change of the stamping assembly 10. This ensures that the surface of the component has sufficient lubricating oil when it rotates to the bottom next time. In this way, the device can maintain sufficient lubrication between the device and the surface of the raw material during each stamping process, avoiding damage to the surface of the raw material during stamping and ensuring the forming quality of the mold.

[0020] Please see Figure 1-3 A wax mold casting mold cutting and forming device includes a pressing component 4, which includes a top block 41. The bottom sides of the top block 41 are symmetrically provided with matching grooves 42. The middle of the two sides of the top block 41 are respectively fixedly installed with connecting frames 43. The lower surface of the top block 41 is symmetrically fixedly installed with a first elastic telescopic rod 44. The bottom end of the first elastic telescopic rod 44 is fixedly installed with a pressure ring 45. The middle of the lower surface of the top block 41 is provided with a central pressure groove 46. The interior of the top block 41 is provided with an oil storage chamber. The lower surface of the top block 41 is fixedly installed with a drive rack 47. In this embodiment, it should be noted that the adapter groove 42 is located at the position of the cross frame 6, the connecting frame 43 is L-shaped, the number of the first elastic telescopic rods 44 is four and they are symmetrically arranged in pairs at one end of the lower surface of the top block 41, the two sides of the central pressure groove 46 are provided with beveled structures, the outer frame size of the bevel is larger than the inner frame size of its center, the bottom of the oil storage chamber inside the top block 41 is provided with a squeezing sponge, the squeezing sponge is in communication with the chamber, the drive rack 47 meshes with the adjustment drive assembly 9, so that when the top block 41 is driven to move down by the electric hydraulic rod 3, the pressure ring 45 can be driven to press against the surface of the raw material plate first, ensuring that the raw material plate will not move randomly during the stamping process, thereby ensuring the accuracy and effect of the stamping. After the stamping assembly 10 completes the stamping, it rotates to exchange the two ends. After the exchange, when the structure rotates to the upper position during the next stamping, it can automatically contact the squeezing sponge to apply oil, ensuring that the stamping process will not cause wear to the surface of the raw material plate when it rotates to the lower position next time.

[0021] Please see Figure 4-8 A wax mold casting die cutting and forming device includes a pull adjustment component 8, which includes an outer shell 81. A separation contact plate 82 is fixedly installed at the top of the outer shell 81. An inner ring plate 83 is movably installed inside the outer shell 81. A through groove 84 is opened in the middle of the bottom of the inner ring plate 83. A suspension plate 85 is movably arranged inside the outer shell 81. An elastic pull rope 86 is fixedly installed at the bottom of the suspension plate 85. A support block 87 is fixedly installed at the bottom of the elastic pull rope 86. First suspension ends 88 are fixedly installed on both sides of the outer shell 81. In this embodiment, it should be noted that the outer shell 81 has U-shaped vertical grooves on both sides for installation. A protruding short rod is provided on the lower surface of the separation contact plate 82, and this protruding short rod is positioned directly opposite the through groove 84. The top of the inner ring plate 83 is fixedly connected to the lower surface of the top block 41. Mutually attracting permanent magnet blocks are provided inside the bottom of the inner ring plate 83 and inside the suspension plate 85. An inner cavity is provided at the bottom of the outer shell 81. The support block 87 is movably positioned within the inner cavity, and its thickness is less than the height of the inner cavity. The first suspension end 88 is movably engaged with the insertion rod 11. Limiting extension rods are provided at both ends of the insertion rod 11. The upward movement of the top block 41 can drive the inner ring plate 83 to move upward, thereby pulling the bottom suspension plate 85 to move. The suspension plate 85 then pulls the support block 87 to the top of the inner cavity at the bottom of the outer shell 81 through the elastic rope 86, thereby lifting the entire outer shell 81 upward, thereby driving the adjustment drive assembly 9 connected to it to move upward. This allows the adjustment drive assembly 9 to engage with the internal structure of the stamping assembly 10, thereby converting the upward movement of the pressing assembly 4 into the lateral movement of the local structure in the adjustment drive assembly 9. This allows the stamping assembly 10 to rotate and switch the upper and lower ends to achieve secondary stamping and oil coating.

[0022] Please see Figure 4-8 A wax mold casting die cutting and forming device includes an adjustment drive assembly 9, which includes a central block 91. A second suspension end 92 is fixedly installed on the side of the central block 91, and a support plate 93 is fixedly installed on the bottom of the central block 91. A sliding groove 94 is provided on the support plate 93. A first rotating wheel 95 and a second rotating wheel 96 are rotatably installed on the end of the central block 91. A first gear 97 is fixedly installed on the side of the second rotating wheel 96. A drive belt 98 is movably sleeved on the first rotating wheel 95 and the second rotating wheel 96. A drive tooth plate 99 is fixedly installed on the end of the drive belt 98. In this embodiment, it should be noted that the central block 91 consists of a central disk and three extended rods evenly spaced on the disk, one of which is vertically upward. The second suspension end 92 is movably engaged with the insertion rod 11. There are two first rotating wheels 95, which are rotatably mounted at the lower ends of the central block 91. The first gear 97 meshes with the drive rack 47. The drive gear plate 99 is slidably disposed inside the slide groove 94, and its upper surface is separably meshed with the internal structure of the stamping assembly 10. The length of the teeth on the drive rack 47 is equal to that of the first gear 97. Half the arc length of 7, so that the upward movement of the drive rack 47 can drive the first gear 97 to rotate, and then drive the first wheel 95 to rotate through the second wheel 96. The first wheel 95 can then drive the drive tooth plate 99 to move laterally through the drive belt 98 sleeved on it. Since it is an upward movement process, the pressing component 4 will pull the inner ring plate 83 to drive the outer shell 81 and the adjusting drive component 9 to move upward as a whole, so that the drive tooth plate 99 meshes with the stamping component 10, thus driving the stamping component 10 to rotate to change the end, thereby realizing the staged stamping operation.

[0023] Please see Figure 1-5 A wax mold casting mold cutting and forming device includes a stamping assembly 10, the stamping assembly 10 includes a support block 101, a first punch 102 and a second punch 103 are fixedly installed at both ends of the support block 101 respectively, and a second gear 104 is fixedly installed on the outer side of the support block 101. In this embodiment, it should be noted that the outer edge of the second punch 103 is provided with a rounded corner structure, the coverage area of ​​the first punch 102 and the second punch 103 is the same, the second gear 104 is fixedly set in the middle of the side of the support block 101, the second gear 104 passes through the side plate 7 and is set above the drive tooth plate 99, and the end of the limiting member 12 is provided with a limiting arm that can rotate automatically. In this way, during the upward movement of the pressing component 4, the support block 101 will be driven to rotate around the rotation axis of the second gear 104 by adjusting the transmission of the drive component 9, and the pressing component 10 will automatically rotate half a turn under the drive of the preceding structure, and will automatically stop under the action of the limiting arm of the limiting member 12. In the subsequent pressing process, the pressing component 4 can be used to correct the overall posture of the pressing component 10 to a vertical state, thereby ensuring the pressing effect.

[0024] Working principle: The raw material plate is conveyed to the corresponding position on the upper surface of the base plate 1. Then, the electric hydraulic rod 3 is activated to drive the top block 41 to move downward. The top block 41 compresses the first elastic telescopic rod 44, causing the pressure ring 45 to adhere to the surface of the raw material plate. After continuing to move downward, the second punch 103 moves downward to perform the initial punching on the surface of the raw material plate. After the punching is completed, the electric hydraulic rod 3 reverses its direction to drive the pressing component 4 to move upward. During the upward movement, the inner ring plate 83 is pulled upward, and the inner ring plate 83 drives the suspension plate 85 to move upward synchronously, thereby stretching the elastic rope 86. The stretching of the elastic rope 86 causes the support block 87 to support the center block 91 to move upward. The center block 91 causes the slide groove 94 to lift the drive gear plate 99 to move upward and mesh with the second gear 104. At the same time, during the upward movement, the drive rack 47 also meshes with the first gear 97. The upward-moving drive rack 47 drives the first gear 97. The first gear 97 rotates, which in turn drives the second rotating wheel 96 to rotate. The second rotating wheel 96 drives the drive gear plate 99 to move laterally in the slide groove 94 via the drive belt 98, thereby causing the second gear 104 to rotate. The rotation of the second gear 104 causes the first punch 102 and the second punch 103 to exchange positions, so that the second punch 103 rotates to the top and the first punch 102 rotates to the bottom. At this time, the second punch 103 at the top will contact the extrusion sponge set inside the central pressure groove 46 in the next stamping process, and replenish the oil on its surface. During the downward movement, the central pressure groove 46 will limit and correct the first punch 102 or the second punch 103 to a vertical state. The downward pressing of the first punch 102 when it rotates to the bottom is a secondary stamping. After the secondary stamping is completed, all the stamping operations at the current position are completed. Then, the above operations can be repeated.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
