Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, specifically relating to a die casting mold for metal sheets. 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. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools, eliminating shrinkage cavities and porosity defects in the blank and achieving a forged, fragmented grain structure. This significantly improves the overall mechanical properties of the blank.

[0003] Existing die-casting molds for metal sheets typically produce metal sheets of fixed thickness. When it is necessary to produce metal sheets of different thicknesses, the entire mold often needs to be replaced. This not only increases production costs, but also leads to low production efficiency due to frequent mold replacements, making it impossible to meet diverse production needs. Utility Model Content

[0004] The purpose of this invention is to provide a die-casting mold for metal sheets, which solves the problem that existing die-casting molds for metal sheets typically produce metal sheets of fixed thickness. When it is necessary to produce metal sheets of different thicknesses, the entire mold often needs to be replaced, which not only increases production costs but also leads to low production efficiency due to frequent mold replacements, making it impossible to meet diverse production needs.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A die-casting mold for metal sheets includes an upper mold, an upper mold core fixedly connected to the bottom of the upper mold, a lower mold fitted to the bottom of the upper mold, a through hole inside the lower mold, the inner wall of the through hole fitting to the surface of the upper mold core, the lower mold core fitted to the inner wall of the through hole, a connecting column fixedly connected to the bottom of the lower mold core, a rectangular block fixedly connected to the bottom of the connecting column, a rectangular hole inside the rectangular block, a cylinder fitted to the inner wall of the rectangular hole, first vertical plates fixedly connected to both ends of the cylinder, a guide ring sleeved on the surface of the first vertical plate, the upper surface of the guide ring fixedly connected to the bottom of the lower mold, a second vertical plate fixedly connected to the left side of the first vertical plate, a hydraulic push rod fixedly connected to the left side of the second vertical plate, a connecting block fixedly connected to the right end of the hydraulic push rod, a column fixedly connected to the bottom of the lower mold, and a base plate fixedly connected to the bottom of the guide ring, the bottom of the connecting block, and the bottom of the column.

[0007] The present invention is further configured such that a horizontal plate is fixedly connected to the left side of the lower mold, a scale is fixedly connected to the upper surface of the horizontal plate, a rectangular tube is attached to the bottom of the horizontal plate and the upper surface of the scale, the bottom of the rectangular tube is fixedly connected to the upper surface of the second vertical plate, and an observation hole is provided on the upper surface of the rectangular tube, the observation hole being located above the scale.

[0008] The present invention is further configured such that threaded holes are provided on both the upper and lower sides of the rectangular tube, and positioning bolts are threadedly connected to the inner walls of the threaded holes. A positioning circular hole is provided inside the horizontal plate, and the inner wall of the positioning circular hole is in contact with the surface of the positioning bolt.

[0009] The present invention is further configured such that the rectangular hole has an angle of 30° with the horizontal plane, the length of the rectangular hole is greater than the diameter of the cylinder, and the width of the rectangular hole is equal to the diameter of the cylinder.

[0013] This utility model discloses a metal sheet die-casting mold comprising a lower die core, a connecting column, a rectangular block, a rectangular hole, a cylinder, a first vertical plate, a guide ring, a second vertical plate, a hydraulic push rod, and a connecting block. When the hydraulic push rod controls the second vertical plate to move left or right, the cylinder can move left or right through the cooperation of the second vertical plate, the first vertical plate, and the guide ring. Furthermore, the position of the lower die core within the through hole changes through the cooperation of the cylinder and the rectangular hole.

[0014] This utility model discloses a metal sheet die-casting mold. Through the cooperation of a horizontal plate, a scale, a rectangular tube, and an observation hole, the user can intuitively judge the distance between the second vertical plate and the connecting block. Furthermore, when adjusting the position of the lower mold core in the through hole, the user can quickly determine whether the hydraulic push rod has moved the second vertical plate to the designated position by observing the reading in the observation hole. At the same time, when the threaded hole is aligned with the positioning round hole, the positioning bolt can be inserted into the positioning round hole by screwing it into the threaded hole. The cooperation between the positioning bolt and the positioning round hole can lock the second vertical plate, thereby reducing the force on the hydraulic push rod when die-casting metal sheets, and thus effectively improving the service life of the hydraulic push rod.

[0027] 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.

[0028] 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.

[0029] like Figures 1 to 8 As shown, a die-casting mold for metal sheets includes an upper mold 1, an upper mold core 2 fixedly connected to the bottom of the upper mold 1, a lower mold 3 fitted to the bottom of the upper mold 1, a through hole 4 inside the lower mold 3, the inner wall of the through hole 4 fitting to the surface of the upper mold core 2, a lower mold core 5 fitted to the inner wall of the through hole 4, a connecting post 6 fixedly connected to the bottom of the lower mold core 5, a rectangular block 7 fixedly connected to the bottom of the connecting post 6, a rectangular hole 8 inside the rectangular block 7, and a cylinder 9 fitted to the inner wall of the rectangular hole 8. The first vertical plate 10 is fixedly connected to both the front and rear ends. A guide ring 11 is sleeved on the surface of the first vertical plate 10. The upper surface of the guide ring 11 is fixedly connected to the bottom of the lower mold 3. A second vertical plate 12 is fixedly connected to the left side of the first vertical plate 10. A hydraulic push rod 13 is fixedly connected to the left side of the second vertical plate 12. A connecting block 14 is fixedly connected to the right end of the hydraulic push rod 13. A column 15 is fixedly connected to the bottom of the lower mold 3. A base plate 16 is fixedly connected to the bottom of the guide ring 11, the bottom of the connecting block 14, and the bottom of the column 15.

[0030] The rectangular hole 8 has an angle of 30° with the horizontal plane, the length of the rectangular hole 8 is greater than the diameter of the cylinder 9, the width of the rectangular hole 8 is equal to the diameter of the cylinder 9, and there are six positioning holes 23, which are symmetrically distributed with the scale 18 as the center.

[0031] It should be noted that the guide ring 11 allows the first vertical plate 10 to move only left and right, while the hydraulic push rod 13 controls the second vertical plate 12 to move left or right. When the second vertical plate 12 moves to the left, the cylinder 9 moves to the left through the second vertical plate 12 and the first vertical plate 10, and the lower mold core 5 moves upward through the cooperation of the cylinder 9 and the rectangular hole 8. When the second vertical plate 12 moves to the right, the cylinder 9 moves to the right through the second vertical plate 12 and the first vertical plate 10, and the lower mold core 5 moves downward through the cooperation of the cylinder 9 and the rectangular hole 8. At the same time, by changing the position of the lower mold core 5 in the through hole 4, the die-casting mold can directly process metal sheets of different thicknesses.

[0032] like Figures 1 to 10As shown, a horizontal plate 17 is fixedly connected to the left side of the lower mold 3, and a scale 18 is fixedly connected to the upper surface of the horizontal plate 17. A rectangular tube 19 is attached to both the bottom of the horizontal plate 17 and the upper surface of the scale 18. The bottom of the rectangular tube 19 is fixedly connected to the upper surface of the second vertical plate 12. An observation hole 20 is opened on the upper surface of the rectangular tube 19. The observation hole 20 is located above the scale 18. Threaded holes 21 are opened on both the upper and lower sides of the rectangular tube 19. A positioning bolt 22 is threadedly connected to the inner wall of the threaded hole 21. A positioning round hole 23 is opened inside the horizontal plate 17. The inner wall of the positioning round hole 23 is attached to the surface of the positioning bolt 22. A reinforcing ring 24 is fixedly connected to the surface of the horizontal plate 17. The right side of the reinforcing ring 24 is fixedly connected to the left side of the lower mold 3.

[0033] It should be noted that the combination of the horizontal plate 17, the scale 18, the rectangular tube 19, and the observation hole 20 allows the user to intuitively judge the distance between the second vertical plate 12 and the connecting block 14. Furthermore, when adjusting the position of the lower mold core 5 within the through hole 4, the user can quickly determine whether the hydraulic push rod 13 has moved the second vertical plate 12 to the designated position by observing the reading in the observation hole 20. Simultaneously, when the threaded hole 21 aligns with the positioning hole 23, the positioning bolt 22 can be screwed into the threaded hole 21, allowing it to be inserted into the positioning hole 23. The cooperation between the positioning bolt 22 and the positioning hole 23 locks the second vertical plate 12, thereby reducing the force on the hydraulic push rod 13 during die-casting of metal sheets and effectively improving the service life of the hydraulic push rod 13. Additionally, the reinforcing ring 24 makes the fixation between the horizontal plate 17 and the lower mold 3 more secure.

[0034] The working principle of this utility model is as follows: When it is necessary to increase the thickness of the metal sheet processed by the die-casting mold, the hydraulic push rod 13 is started and drives the second vertical plate 12 to move horizontally to the right. The first vertical plate 10, which is rigidly connected, drives the cylinder 9 to move to the right synchronously. Since the cylinder 9 and the rectangular hole 8 of the rectangular block 7 are fitted with an inclined surface (the inner wall of the rectangular hole 8 is provided with an inclined guide surface), when the cylinder 9 moves to the right, it will push the rectangular block 7 to move downward in the vertical direction. The rectangular block 7 is fixedly connected to the lower mold core 5 through the connecting column 6, thereby driving the lower mold core 5 to move downward, so that the cavity height between the upper mold core 2 and the lower mold core 5 increases in the mold closing state, and the thickness of the processed metal sheet increases.

[0035] When it is necessary to reduce the thickness of the metal sheet processed by the die-casting mold, the hydraulic push rod 13 is activated and drives the second vertical plate 12 to move horizontally to the left. The first vertical plate 10, which is rigidly connected, drives the cylinder 9 to move to the left in sync. Since the cylinder 9 and the rectangular hole 8 of the rectangular block 7 are fitted with an inclined surface (the inner wall of the rectangular hole 8 is provided with an inclined guide surface), when the cylinder 9 moves to the left, it will push the rectangular block 7 to move upward in the vertical direction. The rectangular block 7 is fixedly connected to the lower mold core 5 through the connecting column 6, thereby driving the lower mold core 5 to move upward, so that the cavity height between the upper mold core 2 and the lower mold core 5 is reduced in the mold-closed state, and the thickness of the processed metal sheet is reduced.

[0036] 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.
