Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molds, and specifically relates to a die-casting mold that is convenient for demolding. Background Art

[0002] A die-casting mold is a key tool for die-casting processes, mainly used to inject molten metal into the mold cavity under high pressure, quickly cool it, and form parts with the required shape. Die-casting processes are widely used in industries such as automotive, aerospace, electronics, and household appliances to produce metal parts with complex shapes, high precision, and high surface quality. The die-casting process injects molten metal (such as aluminum alloy, magnesium alloy, zinc alloy, etc.) into the mold cavity under high pressure, quickly cools and solidifies to form the required part shape. The die-casting process has the advantages of high efficiency, high precision, and high surface quality, and is suitable for mass production.

[0003] The patent document with the Chinese patent authorization announcement number CN118635473A discloses a die-casting mold with convenient demolding, including a fixed part, a die-casting part, a cooling part, and a movable part; by fixing the telescopic frame on the movable plate, when the movable plate separates from the mating plate, the spring on the telescopic frame pushes the mating plate to maintain the connection between the mating plate and the forming block, and after moving a certain distance, the telescopic frame drives the mating block to adjust, forcing the mating block to separate from the forming block for demolding.

[0004] When the above patent is used, the side connection plate is pulled by the telescopic frame to separate the mating plate from the forming block and expose the internal workpiece, facilitating the demolding of the workpiece. However, when the above technical solution is used, it is not considered that the workpiece may be closely attached to the mold cavity during the forming process. Although the telescopic frame and the mating plate can pull the side connection plate and expose the workpiece, there is a lack of sufficient power or structure to push the workpiece away from the mold, resulting in difficult demolding and affecting production efficiency.

[0015] Preferably, an anti-slip pad is arranged at the bottom of the bottom plate, and the anti-slip pad is made of rubber material.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: 1. By starting the motor in the present invention, the output end of the motor drives the first rotating rod to rotate. The first bevel gear on the first rotating rod rotates accordingly, and the second bevel gear meshing with the first bevel gear also rotates. The rotation of the second bevel gear drives the cross bar to rotate, and the rotation of the cross bar drives the worm on the cross bar to rotate. The rotation of the worm drives the worm gear meshing with the worm to rotate. The rotation of the worm gear is converted into the rotation of the connecting rod, and then drives the threaded column to rotate on the partition plate. Due to the threaded connection between the threaded column and the threaded sleeve, when the threaded column rotates, the threaded sleeve will move up and down along the threaded column. The up and down movement of the threaded sleeve drives the lifting of the push template connected thereto. When the threaded sleeve moves upward, the push template ejects the formed workpiece from the cavity of the fixed mold, applies a uniform ejection force to the formed workpiece, and enables the formed workpiece to be smoothly separated from the mold cavity, significantly improving the demoulding efficiency.

[0017] 2. The present invention drives the second rotating rod to start rotating through the linkage component, driving the first gear to rotate together. The rotation of the first gear is transmitted to the arc gear through the meshing relationship, causing the arc gear to start sliding within the arc seat. As the arc gear slides, one end of the arc gear will contact the workpiece and apply a thrust to the workpiece, causing the workpiece to move along the direction of the fixed mold until the workpiece is completely removed from the fixed mold and falls to the predetermined collection position, thus facilitating the collection of the molded mold.

[0018] 3. The present invention pours coolant into the water inlet, and the coolant starts to flow in the upper surrounding pipe and is distributed along the outside of the fixed mold, and further contacts the fixed mold through the cooling bumps. Subsequently, it flows into the lower surrounding pipe. During the flow process, the coolant continuously absorbs the heat generated by the fixed mold, thereby reducing the temperature of the fixed mold and shortening the molding time of the workpiece.

Detailed implementation mode

[0030] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation modes.

[0031] See Figures 1 to 10 As shown, the present invention provides a die-casting mold that facilitates demolding, including a bottom plate 1. A linear actuator 2 is arranged on the top of the bottom plate 1. The working end of the linear actuator 2 is provided with a top plate 3. A moving mold 4 is arranged at the bottom of the top plate 3. A gating system 5 is arranged on the top of the top plate 3. A filtering assembly for filtering impurities in the pouring liquid is arranged in the gating system 5. A fixed mold 6 is arranged on the top of the bottom plate 1. A demolding assembly 7 is arranged in the fixed mold 6. The demolding assembly 7 includes a push template 71 for ejecting the formed workpiece and a vertical driving component for driving the movement of the push template 71. An discharging assembly 8 for pushing out the formed workpiece is further arranged on one side of the fixed mold 6. A linkage assembly for ensuring the coordinated movement between the two is arranged between the vertical driving component and the discharging assembly 8. A cooling component 9 for accelerating the forming of the workpiece is arranged outside the fixed mold 6.

[0032] By starting the linear drive 2, the linear drive 2 is a cylinder, and the linear drive 2 drives the top plate 3 and the moving mold 4 to move downward. The moving mold 4 closes with the fixed mold 6 to form a complete cavity. The molten metal is injected into the cavity through the pouring gate 5, and the filtering component filters the impurities in the molten metal to ensure the internal quality of the casting. The cooling component 9 starts to work, rapidly cools the fixed mold 6 and the moving mold 4, accelerates the solidification of the molten metal, and shortens the molding time. When the workpiece is formed, the linear drive 2 drives the top plate 3 and the moving mold 4 to move upward. The vertical drive component is started, and the push template 71 is pushed upward to eject the formed workpiece, applying a uniform ejection force to the formed workpiece, so that the formed workpiece is smoothly separated from the mold cavity, significantly improving the demolding efficiency. At the same time, the linkage component coordinates the movement of the discharging component 8 to push the ejected workpiece out of the fixed mold 6 to complete the demolding process. A collection box can be installed on one side of the fixed mold 6, and the ejected workpiece will automatically fall into the collection box, facilitating the collection of the formed mold.

[0033] See Figures 4 to 8 As shown, the vertical drive component includes a first support frame 72, a connection box 76, and a cross bar 711; the first support frame 72 is arranged at the bottom of the bottom plate 1, a first rotating rod 73 is arranged inside the first support frame 72, a motor 75 is arranged on one side of the first support frame 72, the output end of the motor 75 is connected to the first rotating rod 73, and a first bevel gear 74 is also arranged on the first rotating rod 73; the connection box 76 is arranged at the bottom of the bottom plate 1 on one side of the first support frame 72, a partition 77 is arranged inside the connection box 76, a threaded column 78 is arranged at the top of the partition 77, a threaded sleeve 79 is threadedly connected to the threaded column 78, the top of the threaded sleeve 79 is connected to the bottom of the push template 71, a connecting rod 710 is arranged at the bottom of the partition 77, the top of the connecting rod 710 is connected to the bottom of the threaded column 78, and a worm gear 714 is also sleeved on the connecting rod 710; the cross bar 711 is horizontally arranged inside the connection box 76 on one side of the worm gear 714, a worm 712 is arranged on the cross bar 711, the worm 712 meshes with the worm gear 714, one end of the cross bar 711 penetrates through one side of the connection box 76 and extends outward, and a second bevel gear 713 is arranged at the extended end of the cross bar 711, and the second bevel gear 713 meshes with the first bevel gear 74.

[0034] By starting the motor 75, the output end of the motor 75 drives the first rotating rod 73 to rotate. The first bevel gear 74 on the first rotating rod 73 rotates accordingly, and the second bevel gear 713 meshing with the first bevel gear 74 also rotates. The rotation of the second bevel gear 713 drives the cross bar 711 to rotate, and the rotation of the cross bar 711 drives the worm 712 on the cross bar 711 to rotate. The rotation of the worm 712 drives the worm gear 714 meshing with the worm 712 to rotate. The rotation of the worm gear 714 is converted into the rotation of the connecting rod 710, which in turn drives the threaded column 78 to rotate on the partition plate 77. Due to the threaded connection between the threaded column 78 and the threaded sleeve 79, when the threaded column 78 rotates, the threaded sleeve 79 moves up and down along the threaded column 78. The up and down movement of the threaded sleeve 79 drives the lifting of the push template 71 connected thereto. When the threaded sleeve 79 moves upward, the push template 71 ejects the formed workpiece from the cavity of the fixed mold 6, applying a uniform ejection force to the formed workpiece, enabling the formed workpiece to be smoothly separated from the mold cavity, and significantly improving the demolding efficiency.

[0035] See Figure 4 As shown, a first spring 715 is further provided at the bottom of the push template 71 inside the fixed mold 6.

[0036] Before the push template 71 starts to move upward, the first spring 715 is already in a certain pre-tightened state, providing an additional power reserve for the subsequent demolding process. With the continuous drive of the vertical drive component, the push template 71 starts to move upward. At the same time, the first spring 715 also starts to gradually release its pre-tightening force, and together with the push template 71, ejects the workpiece from the mold cavity, thereby enhancing the stability of the demolding process.

[0037] See Figures 5 to 8 As shown, the discharging assembly 8 includes an arc seat 81 and a second support frame 83; the arc seat 81 is arranged on one side of the fixed mold 6, and an arc gear 82 is slidably arranged inside the arc seat 81; the second support frame 83 is arranged at the bottom of the bottom plate 1, a second rotating rod 84 is arranged on the second support frame 83, and a first gear 85 is arranged on the second rotating rod 84, and the first gear 85 meshes with the arc gear 82.

[0038] When discharging is required, the second rotating rod 84 is driven to rotate through the linkage assembly, driving the first gear 85 to rotate together. The rotation of the first gear 85 is transmitted to the arc gear 82 through the meshing relationship, causing the arc gear 82 to slide inside the arc seat 81. As the arc gear 82 slides, one end of the arc gear 82 will contact the workpiece and apply a thrust to the workpiece, causing the workpiece to move along the direction of the fixed mold 6 until the workpiece is completely removed from the fixed mold 6 and falls to the predetermined collection position, thus facilitating the collection of the formed mold.

[0039] See Figures 5 to 8As shown, the linkage assembly includes a first synchronous pulley 86, a second synchronous pulley 87, and a synchronous belt 88; the first synchronous pulley 86 is arranged on the first rotating rod 73; the second synchronous pulley 87 is arranged on the second rotating rod 84, and the synchronous belt 88 is sleeved on the first synchronous pulley 86 and the second synchronous pulley 87.

[0040] When the first rotating rod 73 is driven by the motor 75 to rotate, the first synchronous pulley 86 also rotates accordingly. Since the synchronous belt 88 is sleeved on the first synchronous pulley 86 and the second synchronous pulley 87, when the first synchronous pulley 86 rotates, it will drive the second synchronous pulley 87 to rotate, and the rotation of the second synchronous pulley 87 drives the second rotating rod 84, thereby realizing the synchronous movement of the push template 71 and the arc gear 82.

[0041] See Figure 9 As shown, the cooling component 9 includes an upper surrounding pipe 91; the upper surrounding pipe 91 is sleeved on the outside of the fixed mold 6, a water inlet 92 is arranged on one side of the upper surrounding pipe 91, a cooling bump 93 is communicated with the bottom of the upper surrounding pipe 91, a lower surrounding pipe 94 is communicated with the bottom of the cooling bump 93, and a water outlet 95 is arranged on one side of the lower surrounding pipe 94.

[0042] By pouring the coolant into the water inlet 92, the coolant starts to flow in the upper surrounding pipe 91, is distributed along the outside of the fixed mold 6, and further contacts the fixed mold 6 through the cooling bump 93. Subsequently, it flows into the lower surrounding pipe 94. During the flowing process, the coolant continuously absorbs the heat generated by the fixed mold 6, thereby reducing the temperature of the fixed mold 6 and shortening the molding time of the workpiece. In order to keep the temperature of the fixed mold 6 within an appropriate range, the coolant needs to be continuously injected, circulated, and discharged. It can be cooled by an external cooling system, such as a heat exchanger, and the cooled coolant can be recycled and re-injected into the water inlet 92.

[0043] See Figure 10 As shown, the filtering component includes a filter screen 51 and a support block 52; the support block 52 is arranged on the inner wall of the pouring port 5; the filter screen 51 is arranged on the support block 52, and a disassembly and assembly component for fixing the filter screen 51 is arranged on the pouring port 5.

[0044] Before pouring, place the filter screen 51 on the support block 52 and fix the filter screen 51 in the pouring port 5 through the disassembly and assembly component to prevent the filter screen 51 from falling off or moving during the pouring process. When the molten metal flows into the mold through the pouring port 5, the molten metal will pass through the filter screen 51, and the filter screen 51 filters the impurities in the metal liquid to ensure the internal quality of the casting.

[0045] See Figure 10As shown, the disassembly and assembly parts include a bare rod 53; the bare rod 53 is provided with two sides of the pouring port 5, a limit plate 54 is provided at one end of the bare rod 53, a pull plate 55 is slidably provided on the bare rod 53, and a second spring 56 is also sleeved on the bare rod 53, one end of the second spring 56 abuts against one side of the limit plate 54, and the other end of the second spring 56 abuts against one side of the pull plate 55, a plug-in block 57 is provided on one side of the pull plate 55, and an abutting portion is provided at one end of the plug-in block 57, a plug-in groove that can be plugged with the abutting portion is provided on the filter screen 51, and a handle 58 is provided on the other side of the pull plate 55.

[0046] When the filter 51 needs to be cleaned or replaced, the handle 58 is pulled to drive the pull plate 55 to move, and the pull plate 55 moves on the light rod 53 and squeezes the second spring 56 until the pull plate 55 drives the plug-in block 57 to completely disengage from the plug-in slot on the filter 51, thereby completing the removal of the filter 51. When it is necessary to install, the handle 58 is pulled to align the plug-in slot on the filter 51 with the abutment portion of the plug-in block 57, and the handle 58 is released.

[0047] See also Figure 10 As shown, a handle is provided on the top of the filter screen 51.

[0048] The provision of the handle makes it convenient for staff to take the filter 51 .

[0049] See also Figure 1 As shown, a non-slip pad is arranged at the bottom of the base plate 1, and the non-slip pad is made of rubber material.

[0050] The anti-skid pad made of rubber material increases the friction between the bottom plate 1 and the contact surface, thereby preventing the bottom plate 1 from sliding or shifting during operation.

[0051] By starting the linear actuator 2, which is a cylinder, the linear actuator 2 drives the top plate 3 and the moving mold 4 to move downward. The moving mold 4 closes with the fixed mold 6 to form a complete cavity. The molten metal is injected into the cavity through the pouring gate 5. When the molten metal flows into the mold through the pouring gate 5, the molten metal will pass through the filter screen 51, and the filter screen 51 filters the impurities in the molten metal to ensure the internal quality of the casting. Subsequently, by pouring the coolant into the water inlet 92, the coolant starts to flow in the upper surrounding pipe 91, and is distributed along the outside of the fixed mold 6, and further contacts the fixed mold 6 through the cooling bumps 93. Then, it flows into the lower surrounding pipe 94. During the flow process, the coolant continuously absorbs the heat generated by the fixed mold 6, thereby reducing the temperature of the fixed mold 6 and shortening the forming time of the workpiece. In order to keep the temperature of the fixed mold 6 within the appropriate range, the coolant needs to be continuously injected, circulated and discharged. It can be cooled by an external cooling system, such as a heat exchanger. The cooled coolant can be recycled and re-injected into the water inlet 92 to accelerate the solidification of the molten metal and shorten the forming time. When the workpiece is formed, the linear actuator 2 drives the top plate 3 and the moving mold 4 to move upward, and the motor 75 is started. The output end of the motor 75 drives the first rotating rod 73 to rotate. The first bevel gear 74 on the first rotating rod 73 rotates accordingly, and the second bevel gear 713 meshing with the first bevel gear 74 also rotates. The rotation of the second bevel gear 713 drives the cross bar 711 to rotate, and the rotation of the cross bar 711 drives the worm 712 on the cross bar 711 to rotate. The rotation of the worm 712 drives the worm gear 714 meshing with the worm 712 to rotate. The rotation of the worm gear 714 is converted into the rotation of the connecting rod 710, which in turn drives the threaded column 78 to rotate on the partition 77. Due to the threaded connection between the threaded column 78 and the threaded sleeve 79, when the threaded column 78 rotates, the threaded sleeve 79 will move up and down along the threaded column 78. The up and down movement of the threaded sleeve 79 drives the lifting of the ejector plate 71 connected to it. When the threaded sleeve 79 moves upward, the ejector plate 71 ejects the formed workpiece from the cavity of the fixed mold 6, applying a uniform ejection force to the formed workpiece, so that the formed workpiece is smoothly separated from the mold cavity, significantly improving the demolding efficiency. When the first rotating rod 73 is driven by the motor 75 to rotate, the first synchronous pulley 86 also rotates accordingly. Since the synchronous belt 88 is sleeved on the first synchronous pulley 86 and the second synchronous pulley 87, when the first synchronous pulley 86 rotates, it will drive the second synchronous pulley 87 to rotate. The rotation of the second synchronous pulley 87 drives the second rotating rod 84 to rotate, and the second rotating rod 84 drives the first gear 85 to rotate together. The rotation of the first gear 85 is transmitted to the arc gear 82 through the meshing relationship, causing the arc gear 82 to start sliding within the arc seat 81.As the arc-shaped gear 82 slides, the push template 71 will first eject the formed workpiece. As the arc-shaped gear 82 slides within the arc-shaped seat 81, after the push template 71 ejects the formed workpiece, one end of the arc-shaped gear 82 will contact the workpiece and apply a thrust to the workpiece, causing the workpiece to move along the direction of the fixed mold 6 until the workpiece completely disengages from the fixed mold 6 and falls to the predetermined collection position, thus facilitating the collection of the formed mold and completing the demolding process.
