Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, specifically relating to a disc die casting mold with anti-turbulence properties. Background Technology

[0002] Die casting molds are tools used to cast metal parts, specifically for completing the die casting process on a specialized die casting and forging machine. Currently, commercially available disc die casting molds are mainly composed of an upper mold frame, an upper mold cavity, a lower mold frame, and a lower mold cavity. When making a disc, aluminum is first injected into the upper and lower mold cavities through the flow channels within the upper mold frame. After the molten aluminum in the upper and lower mold cavities cools and solidifies, a disc blank is obtained. However, when injecting molten aluminum into the die casting mold, turbulence often occurs, resulting in inaccurate dimensions of the formed disc. Furthermore, because the upper and lower mold cavities are fixed by multiple bolts, disassembly and assembly of the upper and lower mold cavities are quite troublesome. Utility Model Content

[0003] The purpose of this invention is to provide a disc die-casting mold with anti-turbulence, which solves the problem that when molten aluminum is injected into the die-casting mold, turbulence often occurs in the molten aluminum, resulting in inaccurate dimensions of the formed disc. At the same time, it also solves the problem that the upper and lower mold cavities are relatively troublesome to disassemble and assemble.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A disc die-casting mold for preventing turbulence includes an upper mold frame, a lower mold frame fitted to the bottom of the upper mold frame, an upper mold core fitted to the inner wall of the upper mold frame, and a lower mold core fitted to the inner wall of the lower mold frame. Both the upper and lower mold frames have slotted holes inside. U-shaped pillars are fixedly connected to the upper surface of the upper mold core and the bottom of the lower mold core, with the surfaces of the U-shaped pillars fitting against the inner walls of the slotted holes.

The surface of the strip column fits against the inner wall of the U-shaped column. The inner wall of the trapezoidal groove fits against the surface of the U-shaped column.

[0006] The present invention is further configured such that the adjusting bracket includes a first threaded post, a second threaded post, a rotating block, a bearing, and a connecting block. The right side of the first threaded post is fixedly connected to the left side of the second threaded post, and the right side of the second threaded post is fixedly connected to the left side of the rotating block. The surfaces of the first and second threaded posts are both threadedly connected to the inner wall of the threaded cylinder.

Through the cooperation of a strip hole, a U-shaped column, an adjusting bracket, a slider, a trapezoidal groove, and the strip column, the user can disassemble or assemble the upper or lower mold core of the die-casting mold by rotating the rotating block on the adjusting bracket. At the same time, through the inclined surface on the trapezoidal groove, the slider applies a vertical thrust to the U-shaped column during horizontal movement. The thrust on the U-shaped column pushes the upper or lower mold core stuck in the mold frame out of the mold frame, thus facilitating the user to remove the upper or lower mold core stuck in the mold frame.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 12 As shown, a disc die-casting mold for preventing turbulence includes an upper mold frame 1, a lower mold frame 2 fitted to the bottom of the upper mold frame 1, an upper mold core 3 fitted to the inner wall of the upper mold frame 1, and a lower mold core 4 fitted to the inner wall of the lower mold frame 2. Both the interior of the upper mold frame 1 and the interior of the lower mold frame 2 have slotted holes 5. U-shaped pillars 6 are fixedly connected to the upper surface of the upper mold core 3 and the bottom of the lower mold core 4, with the surface of the U-shaped pillars 6 fitting against the inner wall of the slotted holes 5. A first upright column 7 is fixedly connected to the upper surface of the upper mold frame 1, and a first horizontal plate 8 is fixedly connected to the top of the first upright column 7. The bottom of the lower mold frame 2 is fixedly connected to a second column 9, and the bottom of the second column 9 is fixedly connected to a second horizontal plate 10. The bottom of the first horizontal plate 8 and the upper surface of the second horizontal plate 10 are both fixedly connected to an adjusting bracket 11. The surface of the adjusting bracket 11 is threadedly connected to a threaded cylinder 12, and the surface of the threaded cylinder 12 is fixedly connected to a slider 13. The surface of the slider 13 is provided with a trapezoidal groove 14, and the inner wall of the trapezoidal groove 14 is fixedly connected to a strip column 15. The surface of the strip column 15 is in contact with the inner wall of the U-shaped column 6, and the inner wall of the trapezoidal groove 14 is in contact with the surface of the U-shaped column 6.

[0032] The adjusting bracket 11 includes a first threaded post 111, a second threaded post 112, a rotating block 113, a bearing 114, and a connecting block 115. The right side of the first threaded post 111 is fixedly connected to the left side of the second threaded post 112, and the right side of the second threaded post 112 is fixedly connected to the left side of the rotating block 113. The surfaces of the first threaded post 111 and the second threaded post 112 are both threadedly connected to the inner wall of the threaded cylinder 12. The axes of the first threaded post 111, the second threaded post 112, and the rotating block 113 are all on the same horizontal line. The thread direction of the first threaded post 111 is opposite to that of the second threaded post 112. The surfaces of the first threaded post 111 and the second threaded post 112 are both fixedly connected to the inner ring of the bearing 114. The outer ring of the bearing 114 is fixedly connected to the inner wall of the connecting block 115. The bottom of the first horizontal plate 8 and the upper surface of the second horizontal plate 10 are both fixedly connected to the surface of the connecting block 115.

[0033] It should be noted that both the first horizontal plate 8 and the second horizontal plate 10 are in contact with the surface of the slider 13, preventing the slider 13 from rotating with the threaded cylinder 12. When the rotating block 113 rotates, the distance between the left and right sliders 13 changes through the cooperation of the first threaded post 111, the second threaded post 112, and the threaded cylinder 12. When the inner wall of the U-shaped post 6 contacts the surface of the strip post 15, the upper mold core 3 can be fixed inside the upper mold frame 1 through the cooperation of the U-shaped post 6 and the strip post 15. The lower mold core 4 is fixed inside the lower mold frame 2. When the U-shaped column 6 separates from the strip column 15, the upper mold core 3 can separate from the upper mold frame 1, and the lower mold core 4 can separate from the lower mold frame 2. At the same time, through the inclined surface on the trapezoidal groove 14, the slider 13 will apply a vertical thrust to the U-shaped column 6 during horizontal movement. Through the thrust received by the U-shaped column 6, the upper mold core 3 or the lower mold core 4 stuck in the mold frame will be pushed out of the mold frame, making it easier for the user to disassemble the upper mold core 3 or the lower mold core 4 stuck in the mold frame.

[0034] like Figures 1 to 13 As shown, a guide block 16 is fixedly connected to the inner wall of the lower mold core 4. The surface of the guide block 16 is in contact with the inner wall of the lower mold frame 2. A guide groove 17 is provided on the back of the guide block 16. The surface of the guide block 16 is in contact with the surface of the upper mold core 3. A first through hole 18 is provided inside the upper mold core 3. A second through hole 19 is provided inside the upper mold frame 1. A third through hole 20 is provided on the upper surface of the first horizontal plate 8. An injection pipe 21 is fixedly connected to the inner wall of the third through hole 20 and the upper surface of the upper mold frame 1.

[0035] The guide groove 17 is in the shape of an inverted triangle, and the opening direction of the guide groove 17 is aligned with the flow channel on the lower mold core 4. The centers of the first through hole 18, the second through hole 19 and the third through hole 20 are all on the same vertical line.

[0036] It should be noted that the inverted triangular guide groove 17 on the guide block 16 avoids problems such as turbulence when the aluminum liquid enters the upper mold core 3 and the lower mold core 4, so that the cooling rate of each part of the casting is consistent during the solidification process, which is conducive to obtaining more accurate dimensional accuracy and reducing dimensional deviation.

[0037] The working principle of this utility model is as follows: First, the upper mold frame 1 and the lower mold frame 2 are combined together. Then, the molten aluminum is injected into the upper mold core 3 and the lower mold core 4 through the injection pipe 21. The flow channel 17 on the flow guide block 16 prevents turbulence in the molten aluminum during the injection process. After the molten aluminum is formed in the upper mold core 3 and the lower mold core 4, the upper mold frame 1 and the lower mold frame 2 are separated. Then, the formed disc is removed from the lower mold core 4.

[0038] When it is necessary to disassemble the upper mold core 3, first rotate the rotating block 113 of the first horizontal plate 8 to gradually increase the distance between the two sliders 13 with the cooperation of the first threaded column 111, the second threaded column 112 and the threaded cylinder 12. After the U-shaped column 6 separates from the strip column 15, the upper mold core 3 can be taken out from the upper mold frame 1. If the upper mold core 3 is stuck in the upper mold frame 1, continue to rotate the rotating block 113 to make the U-shaped column 6 contact the inclined surface on the trapezoidal groove 14. At this time, through the inclined surface on the trapezoidal groove 14, the slider 13 will apply a vertical thrust to the U-shaped column 6 during the horizontal movement, and through the thrust received by the U-shaped column 6, the upper mold core 3 stuck in the upper mold frame 1 will be pushed out.

[0039] When the upper mold core 3 needs to be installed, first adjust the distance between the left and right sliders 13 to a suitable size by rotating the rotating block 113 of the first horizontal plate 8. Then, insert the upper mold core 3 into the upper mold frame 1 and rotate the rotating block 113 to make the strip column 15 contact the inner wall of the U-shaped column 6. At this time, the upper mold core 3 can be fixed in the upper mold frame 1 by the cooperation of the strip column 15 and the U-shaped column 6.

[0040] When it is necessary to disassemble the lower mold core 4, first rotate the rotating block 113 of the second horizontal plate 10 to gradually increase the distance between the two sliders 13 with the cooperation of the first threaded post 111, the second threaded post 112 and the threaded cylinder 12. After the U-shaped post 6 separates from the strip post 15, the lower mold core 4 can be taken out from the lower mold frame 2. If the lower mold core 4 is stuck in the lower mold frame 2, continue to rotate the rotating block 113 to make the U-shaped post 6 contact the inclined surface on the trapezoidal groove 14. At this time, through the inclined surface on the trapezoidal groove 14, the slider 13 will apply a vertical thrust to the U-shaped post 6 during the horizontal movement, and through the thrust received by the U-shaped post 6, the lower mold core 4 stuck in the lower mold frame 2 will be pushed out.

[0041] When the lower mold core 4 needs to be installed, first adjust the distance between the two sliders 13 to a suitable size by rotating the rotating block 113 of the second horizontal plate 10. Then, insert the lower mold core 4 into the lower mold frame 2 and rotate the rotating block 113 to make the strip column 15 contact the inner wall of the U-shaped column 6. At this time, the lower mold core 4 can be fixed in the lower mold frame 2 by the cooperation of the strip column 15 and the U-shaped column 6.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
