Description

Technical Field

[0001] This invention relates to the field of metal injection molding technology, specifically to a metal injection mold that facilitates material handling. Background Technology

[0002] The rapid development of modern industry, such as automobile manufacturing, electronic equipment, and aerospace, has led to an increasing demand for metal products. These fields require a large number of high-precision, high-performance, and complex-shaped metal parts. Traditional processing methods, such as casting and machining, have certain limitations in meeting the requirements for complex shapes and high precision.

[0003] Patent CN221134009U discloses a precision metal injection mold, including a worktable. A support rod is fixedly connected to the top of the worktable. A rotating plate is used to place materials such as metal powder into a mixing tank. The mixing tank is fitted with a reinforcing ring to ensure sealing. Two sets of connecting frames connected to both ends of the mixing tank are connected to the rotating plate via connecting shafts and connecting columns. Under the action of a drive motor built into the drive shaft, the rotating plate rotates, and the connecting frames then drive the mixing tank to rotate, uniformly mixing the materials inside. After a certain degree of mixing, the material enters the feed pipe through the feed tank. Internally, the device quantitatively injects the final molded material through the injection port. The power supply box heats the material tube through the connecting pipe to form a secondary mixture, achieving multiple mixing of raw materials. At the same time, during the injection process, cooling water pipes are used to accelerate the formation of the mold block, realizing improved work efficiency and quality control of injection molds when performing precision metal injection molding. However, when removing the mold, the mold block needs to be manually removed from the mold, which is time-consuming and laborious, resulting in low mold processing efficiency. Therefore, a metal injection mold that is easy to remove materials is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a metal injection mold that facilitates material handling, addressing the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a metal injection mold for easy material handling, including a support platform, a U-shaped frame fixedly connected to the top of the support platform, a hydraulic cylinder fixedly connected to the top of the U-shaped frame, a U-shaped plate fixedly connected to the top of the support platform, an injection device provided on the inner wall of the support platform, a fixed mold fixedly connected to the top of the support platform, a moving mold fixedly connected to the output end of the hydraulic cylinder, an L-shaped pressure plate fixedly connected to the top of the moving mold, a sliding rod slidably connected to the inner wall of the U-shaped frame via a spring, a force-bearing plate fixedly connected to the circumferential surface of the sliding rod, a lifting frame fixedly connected to the circumferential surface of the sliding rod, a spraying mechanism for spraying a release agent provided on the left side of the U-shaped frame, a demolding mechanism for improving the demolding effect provided on the left side of the fixed mold, and a top plate fixedly connected to the inner wall of the lifting frame. The push rod has a top plate fixedly connected to its circumferential surface. The circumferential surface of the sliding rod is slidably connected to the inner wall of the support platform, and a spring on the surface of the sliding rod provides upward movement power. The inner wall of the fixed mold is slidably connected to the circumferential surface of the push rod, and the push rod is used to eject the molded part. The injection port of the fixed mold is fixedly connected to the discharge port of the injection device through a hose, so that the top plate automatically descends into the groove of the fixed mold, thus no longer interfering with the mold injection process. The mold injection work can be carried out, and the two injection ports can fill the interior of the fixed mold, avoiding gaps that could lead to injection failure. At the same time, the molded part can be ejected, making it convenient for workers to remove the material, thereby improving the material removal speed of the mold. This is especially important for complex-shaped metal products, where material removal is more difficult and requires a lot of time and effort.

[0006] Preferably, the spraying mechanism includes a medicine tank, which is fixedly connected to the left side of the U-shaped frame. A pressure rod is slidably connected to the inner wall of the medicine tank, and an L-shaped rod is fixedly connected to the circumferential surface of the pressure rod. A connecting pipe is fixedly connected to the bottom of the medicine tank. A second U-shaped plate is fixedly connected to the inner wall of the U-shaped frame, and a spraying plate is fixedly connected to the front of the second U-shaped plate. A fixing plate is fixedly connected to the top of the support platform, and a fixing rod is fixedly connected to the inner wall of the fixing plate. A Z-shaped plate is slidably connected to the circumferential surface of the fixing rod via a spring. A third U-shaped plate is fixedly connected to the circumferential surface of the top rod. A stabilizing plate is fixedly connected to the right side of the Z-shaped plate, and a triangular plate is fixedly connected to the top of the third U-shaped plate. The inner wall of the U-shaped frame is in contact with the surface of the L-shaped rod, and the rear of the force-bearing plate is in contact with the front of the L-shaped rod. The connection is fixed, with the right side of the connecting pipe fixedly connected to the left side of the spraying plate. The spraying plate is used to spray the release agent onto the inner wall of the fixed mold. The top of the triangular plate and the bottom of the Z-shaped plate are in contact with each other. When the triangular plate moves, it pushes the Z-shaped plate to move through the squeezing force, so that the release liquid enters the interior of the spraying plate through the connecting pipe. Thus, the injection molding liquid is sprayed into the interior of the fixed mold before molding, which can improve the demolding effect of the mold after the mold is formed and avoid the mold getting stuck on the inner wall of the fixed mold, which would make the mold difficult to demold and affect the processing efficiency of the mold. At the same time, it can slightly clamp and fix the mold when the mold is ejected, so as to avoid the mold from deforming due to incomplete cooling and solidification. It can also facilitate the handling of the mold by robots or manuals during subsequent material handling, and can accurately place the mold in the designated position.

[0007] Preferably, the demolding mechanism includes a connecting plate, which is fixedly connected to the inner wall of the Z-shaped plate. A moving rod is slidably connected to the inner wall of the connecting plate via a spring. A protrusion is fixedly connected to the left side of the fixed mold. A chamfer plate is fixedly connected to the inner wall of the moving rod. A force-bearing rod is slidably connected to the inner wall of the stabilizing plate. A buffer spring is sleeved on the circumferential surface of the force-bearing rod. A clamping plate is fixedly connected to the circumferential surface of the force-bearing rod. The left side of the fixed mold and the right side of the chamfer plate are in contact with each other. During the movement, the chamfer plate will contact the protrusion and move by squeezing force. When demolding the mold, it can impact the surface of the fixed mold, so that a certain gap is generated between the inner wall of the fixed mold and the mold, thereby reducing the stress between the mold and the fixed mold and further improving the demolding effect. At the same time, when the clamping plate is used to fix and clamp the mold, it will exert a squeezing force on the buffer spring, thereby providing a certain buffer during clamping and avoiding the problem of mold deformation caused by excessive clamping force.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This convenient metal injection mold, through the coordinated operation of the support platform, U-shaped frame, hydraulic cylinder, U-shaped plate, injection device, fixed mold, moving mold, L-shaped pressure plate, sliding rod, force plate, lifting frame, ejector rod, and top plate, allows the top plate to automatically descend into the groove of the fixed mold, thus eliminating interference with the injection molding process. This allows for successful injection molding, and the two injection ports ensure the fixed mold is completely filled, preventing voids that could lead to injection failure. Simultaneously, the molded part can be ejected, facilitating material removal by workers and increasing the material removal speed. This is especially important for complex-shaped metal products, where material removal is more difficult and requires significant time and effort.

[0009] 2. This convenient metal injection mold, through the coordinated operation of the agent tank, pressure rod, L-shaped rod, connecting pipe, U-shaped plate, and spraying plate, allows the release fluid to enter the interior of the spraying plate through the connecting pipe. This sprays the injection fluid into the interior of the fixed mold before molding, thereby improving the mold release effect after the mold is formed and preventing the mold from getting stuck on the inner wall of the fixed mold, which would cause difficulties in mold release and affect the processing efficiency of the mold.

[0010] 3. This convenient metal injection mold, through the coordinated operation of the fixed plate, fixed rod, Z-shaped plate, U-shaped plate, stabilizing plate, and triangular plate, can slightly clamp and fix the mold during demolding, preventing deformation of the mold due to incomplete cooling and solidification. It also facilitates the handling of materials by robots or manual labor during subsequent material handling, allowing the mold to be accurately placed in the designated position.

[0011] 4. This convenient metal injection mold, through the coordinated operation of connecting plates, moving rods, protrusions, chamfered plates, force-bearing rods, buffer springs, and clamping plates, can impact the surface of the fixed mold during mold demolding, creating a certain gap between the inner wall of the fixed mold and the mold, thereby reducing the stress between the mold and the fixed mold and further improving the demolding effect. At the same time, when the mold is fixed and clamped, the clamping plate will exert a compressive force on the buffer spring, thus providing a certain buffer during clamping and avoiding the problem of mold deformation caused by excessive clamping force.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-7One embodiment of the present invention is as follows: a metal injection mold for convenient material handling includes a support platform 1, a U-shaped frame 2 fixedly connected to the top of the support platform 1, a hydraulic cylinder 3 fixedly connected to the top of the U-shaped frame 2, a U-shaped plate 4 fixedly connected to the top of the support platform 1, an injection molding device 5 provided on the inner wall of the support platform 1, a fixed mold 6 fixedly connected to the top of the support platform 1, a moving mold 7 fixedly connected to the output end of the hydraulic cylinder 3, an L-shaped pressure plate 8 fixedly connected to the top of the moving mold 7, a sliding rod 9 slidably connected to the inner wall of the U-shaped frame 2 by a spring, a force-bearing plate 10 fixedly connected to the circumferential surface of the sliding rod 9, and a force-bearing plate 10 fixedly connected to the circumferential surface of the sliding rod 9. The lifting frame 11 and the left side of the U-shaped frame 2 are equipped with a spraying mechanism 14 for spraying release agent. The left side of the fixed mold 6 is equipped with a demolding mechanism 15 for improving the demolding effect. The inner wall of the lifting frame 11 is fixedly connected to a top rod 12. The circumferential surface of the top rod 12 is fixedly connected to a top plate 13. The circumferential surface of the sliding rod 9 is slidably connected to the inner wall of the support platform 1. The spring on the surface of the sliding rod 9 is used to provide the upward movement power for the sliding rod 9. The inner wall of the fixed mold 6 is slidably connected to the circumferential surface of the top rod 12. The top rod 12 is used to push out the mold after molding. The injection port of the fixed mold 6 is fixedly connected to the discharge port of the injection device 5 through a hose.

[0016] The spraying mechanism 14 includes a medicine tank 141, which is fixedly connected to the left side of the U-shaped frame 2. A pressure rod 142 is slidably connected to the inner wall of the medicine tank 141, and an L-shaped rod 143 is fixedly connected to the circumferential surface of the pressure rod 142. A connecting pipe 144 is fixedly connected to the bottom of the medicine tank 141. A second U-shaped plate 145 is fixedly connected to the inner wall of the U-shaped frame 2, and a spraying plate 146 is fixedly connected to the front of the second U-shaped plate 145. A fixing plate 147 is fixedly connected to the top of the support platform 1, and a fixing rod 148 is fixedly connected to the inner wall of the fixing plate 147. A Z-shaped plate 149 is slidably connected to the circumferential surface of the fixing rod 148 via a spring. The top rod 12... A U-shaped plate 1410 is fixedly connected to the circumferential surface. A stabilizing plate 1411 is fixedly connected to the right side of the Z-shaped plate 149. A triangular plate 1412 is fixedly connected to the top of the U-shaped plate 1410. The inner wall of the U-shaped frame 2 is in contact with the surface of the L-shaped rod 143. The rear part of the force plate 10 is fixedly connected to the front part of the L-shaped rod 143. The right side of the connecting pipe 144 is fixedly connected to the left side of the spraying plate 146. The spraying plate 146 is used to spray the release agent onto the inner wall of the fixed mold 6. The top of the triangular plate 1412 is in contact with the bottom of the Z-shaped plate 149. When the triangular plate 1412 moves, it will push the Z-shaped plate 149 to move through the squeezing force.

[0017] When mold injection begins, hydraulic cylinder 3 is activated, driving the moving mold 7 to move. The moving mold 7 moves the L-shaped pressure plate 8 downward. During the downward movement of the L-shaped pressure plate 8, it comes into contact with the force plate 10 and squeezes the force plate 10, causing it to move downward. The downward movement of the force plate 10 drives the sliding rod 9 downward, which in turn drives the lifting frame 11 downward. The downward movement of the lifting frame 11 drives the ejector rod 12 downward, which in turn drives the top plate 13 downward. When the top plate 13 is in contact with the inner wall of the fixed mold 6, the moving mold 7 reaches the required position on the inner wall of the fixed mold 6. At this time, the injection molding device 5 is activated, injecting the internal molten metal into the interior of the fixed mold 6 through the pipe. This causes the top plate 13 to automatically descend into the groove of the fixed mold 6, thus no longer interfering with the mold injection process. This allows the mold injection work to proceed, and through the two injection ports, the interior of the fixed mold 6 is filled completely, preventing gaps that could lead to injection failure.

[0018] When the injection molding is completed, the hydraulic cylinder 3 moves upward, driving the moving mold 7 to move upward. The moving mold 7 moves upward, driving the L-shaped pressure plate 8 to move upward. At this time, the pressure plate 10 will no longer be squeezed. The sliding rod 9 will then move upward through the spring reset, thereby driving the top plate 13 to move upward through the above steps, so that the molded mold can be ejected, making it convenient for workers to pick up the material. This can improve the material picking speed of the mold, especially for complex-shaped metal products, where the material picking is more difficult and requires a lot of time and effort.

[0019] Overall working principle: When the mold injection begins, as the top plate 13 fits against the inner wall of the fixed mold 6, the moving mold 7 reaches the required position on the inner wall of the fixed mold 6. At this time, the injection molding device 5 starts to inject the internal molten metal into the interior of the fixed mold 6 through the pipe, so that the top plate 13 automatically descends into the groove of the fixed mold 6, thus no longer interfering with the mold injection. At the same time, it drives the top plate 13 to move upward, thereby ejecting the molded part, making it easier for workers to remove the material, thus improving the material removal speed of the mold. This is especially true for complex-shaped metal products, where material removal is more difficult and requires a lot of time and effort.

[0020] During injection molding, the force plate 10 moves downward, causing the L-shaped rod 143 to move downward. The downward movement of the L-shaped rod 143 causes the pressure rod 142 to move downward. The downward movement of the pressure rod 142 squeezes the release fluid inside the agent tank 141, causing the release fluid to enter the spray plate 146 through the connecting pipe 144. This sprays the injection molding liquid into the interior of the fixed mold 6 before pressing, which improves the mold release effect after the mold is formed and avoids the mold getting stuck on the inner wall of the fixed mold 6, which would make the mold release difficult and affect the processing efficiency of the mold.

[0021] During demolding, the ejector pin 12 moves upward, causing the U-shaped plate 1410 to move upward. The U-shaped plate 1410 then moves the triangular plate 1412 upward. During the upward movement of the triangular plate 1412, it comes into contact with the Z-shaped plate 149 and applies pressure to the Z-shaped plate 149, causing the Z-shaped plate 149 to move backward. The bottom of the Z-shaped plate 149 is equipped with rollers, which reduces friction during extrusion to reduce wear and extend its service life. The backward movement of the Z-shaped plate 149 causes the stabilizing plate 1411 to move backward, which can slightly clamp and fix the mold during mold discharge, preventing deformation caused by incomplete cooling and solidification. It also facilitates handling by a robot or manual labor, allowing the mold to be accurately placed in the designated position.

[0022] Overall working principle: During injection molding, the release fluid enters the interior of the spray plate 146 through the connecting pipe 144, thereby spraying the injection fluid into the interior of the fixed mold 6 before compression molding. This improves the mold release effect after the mold is formed, preventing the mold from getting stuck on the inner wall of the fixed mold 6, which would make mold release difficult and affect the mold processing efficiency. During extrusion, it can reduce friction to reduce the wear of the Z-shaped plate 149, thereby increasing the service life of the Z-shaped plate 149. It can also slightly clamp and fix the mold during mold discharge to prevent the mold from deforming due to incomplete cooling and solidification. It can also fix the position of the mold, making it easy for robots or manual handling.

[0023] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the demolding mechanism 15 includes a connecting plate 151, which is fixedly connected to the inner wall of the Z-shaped plate 149. The inner wall of the connecting plate 151 is slidably connected to a moving rod 152 via a spring. A protrusion 153 is fixedly connected to the left side of the fixed mold 6. A chamfer plate 154 is fixedly connected to the inner wall of the moving rod 152. A force-bearing rod 155 is slidably connected to the inner wall of the stabilizing plate 1411. A buffer spring 156 is sleeved on the circumferential surface of the force-bearing rod 155. A clamping plate 157 is fixedly connected to the circumferential surface of the force-bearing rod 155. The left side of the fixed mold 6 is in contact with the right side of the chamfer plate 154, and the chamfer plate 154 will contact the protrusion 153 during movement and move by squeezing force.

[0024] During mold demolding, the Z-shaped plate 149 moves, causing the moving rod 152 to move backward. The backward movement of the moving rod 152 causes the chamfering plate 154 to move backward. During this movement, the chamfering plate 154 contacts the arc-shaped surface of the protrusion 153, generating a leftward squeezing force that causes it to move to the left. This leftward movement of the chamfering plate 154 moves the moving rod 152, stretching the spring on its surface. After the chamfering plate 154 passes the protrusion 153, it is no longer subject to the squeezing force. At this point, the spring returns to its original position, causing the moving rod 152 to move to the right. The impact on the surface of the fixed mold 6 creates a gap between the inner wall of the fixed mold 6 and the mold, thereby reducing the stress between the mold and the fixed mold 6 and further improving the demolding effect. At the same time, during clamping, the movement of the stabilizing plate 1411 drives the force rod 155 to move, and the force rod 155 moves backward to drive the buffer spring 156 to move. The movement of the buffer spring 156 drives the clamping plate 157 to move. When the mold is fixed and clamped, the clamping plate 157 will exert a compressive force on the buffer spring 156, thereby providing a certain buffer during clamping and avoiding the problem of mold deformation caused by excessive clamping force.

[0025] Overall working principle: After the chamfer plate 154 passes the protrusion 153, the chamfer plate 154 will no longer be subjected to the squeezing force of the chamfer plate 154. At this time, the spring returns to its original position and drives the moving rod 152 to move to the right, which can impact the surface of the fixed mold 6, so that a certain gap is generated between the inner wall of the fixed mold 6 and the mold, reducing the stress between the mold and the fixed mold 6, and further improving the demolding effect. At the same time, the movement of the buffer spring 156 drives the clamping plate 157 to move. When the mold is fixed and clamped, the clamping plate 157 will exert a squeezing force on the buffer spring 156, which can avoid the problem of mold deformation caused by excessive clamping force.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
