Description

Technical Field

[0001] The utility model specifically relates to the technical field of die-casting processing, and specifically is a die-casting processing device for a 3D printer frame. Background Technique

[0002] Die-casting equipment is special mechanical equipment used for die-casting processes. By quickly injecting molten metal into the mold cavity under high pressure, it solidifies and forms, thereby obtaining high-quality castings. Common types of die-casting equipment include: Hot-chamber die-casting machine: Its pressure chamber is immersed in the liquid metal of the heat-insulating crucible, and the injection component is directly installed above the crucible. For example, some small zinc alloy die-casting products are often produced using hot-chamber die-casting machines. Cold-chamber die-casting machine: The pressure chamber is separated from the heat-insulating furnace. During die-casting, liquid metal is scooped from the heat-insulating furnace and poured into the pressure chamber before die-casting. Cold-chamber die-casting machines are suitable for die-casting of various alloys such as aluminum alloys and magnesium alloys, and have a wide range of applications;

[0003] Currently, when traditional die-casting equipment fills molten metal, there may be bubbles inside the molten metal, which will cause bubbles inside the die-casting mold and cannot effectively guarantee the quality of the product; for thin-walled and complex-shaped castings, there may be problems with incomplete filling, which will result in incomplete die-cast products and waste products, reducing the working efficiency of the die-casting equipment;

[0004] After retrieval, Chinese Patent Publication No. CN202011185416.7 discloses a die-casting equipment and die-casting method for a mold; including a workbench, a fixed mold is fixedly installed on the outer wall of the top of the workbench, the outer wall of the top of the workbench is fixedly connected to a frame, a hydraulic cylinder is fixedly connected to the inner wall of the top of the frame, and the hydraulic rod at the bottom of the hydraulic cylinder is fixedly connected to a cleaning device. A moving mold is arranged on the outer wall of the bottom of the cleaning device, a storage bucket is arranged on the outer wall of the left side of the frame, the outer wall of the top of the storage bucket is communicated with a pouring head through a conduit, and the right end of the electric telescopic rod is connected to the pouring head through a clamp. When the moving mold in the device is inserted into the cavity of the fixed mold to process the product, the mounting plate will contact the top wall of the fixed mold, push the moving rod upward, move the guide block inward, and make the moving sleeve drive the cutting knife to move downward to contact the top wall of the fixed mold to cut off the overflowing raw material;

[0005] When the structure in the above patent is used for die-casting of a mold, the molten raw material is added into the stationary mold through the injection head. The injection head is exposed to the air. In this way, when injecting the raw material, external impurities may be doped into the raw material. Moreover, in the injection method in the above patent, a large number of bubbles will be generated inside the stationary mold during the injection process. In this way, when the stationary mold and the moving mold are matched, a large number of bubbles will exist inside the product, which will directly affect the quality of the product. Moreover, when the moving mold and the stationary mold are matched, the raw material inside the stationary mold will be extruded, resulting in insufficient filling of the raw material between the stationary mold and the moving mold, causing the product to be incomplete and reducing work efficiency.

[0006] In view of the above situation, we provide a die-casting processing device for a 3D printer frame. In this device, first, the moving mold and the stationary mold are fitted together. The mold cavity of the stationary mold is communicated with the filling pipeline. During the injection process, pressure is transmitted to the top of the tank body through a pressure tank, so that the molten metal inside the tank body enters the mold cavity of the stationary mold through the filling pipeline. A pressure sensor is arranged at the bottom of the tank body. When the pressure sensor detects pressure transmission, the vibration motor on the filling pipeline is vibrated through the controller. In this way, the situation of bubbles existing in the molten metal can be effectively avoided, ensuring the quality of the formed product. After the moving mold and the stationary mold are fitted together, the driving motor inside the base drives the semi-circular gear to rotate. During the rotation of the semi-circular gear, it meshes with the teeth on the sliding column, realizing the downward sliding of the sliding column. After the semi-circular gear separates from the teeth, the sliding column resets upward under the action of the spring, realizing the knocking on the bottom of the moving mold and the vibration of the moving mold. In this way, it is effectively ensured that the molten metal can effectively fill the mold cavity between the moving mold and the stationary mold during injection, avoiding the situation of defects in the die-cast product caused by insufficient filling, and ensuring the die-casting quality of the product and improving work efficiency. Summary of the Invention

[0007] The purpose of the present invention is to provide a die-casting processing device for a 3D printer frame.

After the moving mold and the stationary mold are matched, the driving motor drives the semi-circular gear to mesh with the teeth on one side of the sliding column, realizing the downward movement of the sliding column. The spring between the top of the sliding column and the fixed support plate is compressed. After the semi-circular gear separates from the teeth, the sliding column resets upward under the action of the spring. When the sliding column resets upward, due to the inertia of the spring, the bottom of the moving mold is knocked, realizing that during the injection process, the molten metal effectively fills the mold cavity between the moving mold and the stationary mold, ensuring the quality of the die-casting mold; to solve the problems in the above background technology.

[0027] Please refer to Figures 1-5 , in the embodiment of the present utility model, a 3D printer frame die-casting processing device includes a base 1; a die-casting assembly 2 is cooperatively installed on the base 1; the die-casting assembly 2 includes a fixed die 24; the bottom of the fixed die 24 is fixedly installed at one end of the base 1, and a moving die 23 is cooperatively arranged on one side of the fixed die 24 where a die cavity is opened; the bottom of the moving die 23 is movably installed on the slide rail 26 through a slider 27; the slide rail 26 is fixedly installed with the base 1; a fixing plate 20 is arranged on one side of the moving die 23 away from the fixed die 24, and the bottom of the fixing plate 20 is fixedly installed at one end of the base 1 away from the fixed die 24; a guide slide rod 25 is arranged between the fixing plate 20, the moving die 23 and the fixed die 24;

[0028] There are two symmetrically arranged moving guide rods 22 between the fixed plate 20 and the moving die 23; one end of the moving guide rod 22 is fixedly installed with the moving die 23; the other end is slidably matched with the fixed plate 20; on the side of the fixed plate 20 away from the moving die 23, an electric push cylinder 21 is fixedly installed, and the push rod of the electric push cylinder 21 penetrates the fixed plate and is fixedly connected with the moving guide rod 22 through a push block 28; on the side of the fixed die 24 away from the moving die 23, a filling assembly 3 is provided.

[0029] Specifically, the filling assembly 3 includes a C-shaped frame 37 fixedly installed with the fixed die 24; one end of the C-shaped frame 37 is fixedly installed with a carrier 32; on the top of the carrier 32, there is a tank body 30; on one side of the tank body 30, there is a pressurizing tank 31; the pressurizing tank 31 is communicated with the top of the tank body 30 through a pressurizing pipe.

[0030] By adopting the above technical solution, during use, first, the electric push cylinder 21 installed on the fixed plate 20 drives the push block 28 to move back and forth. The push block 28 is fixedly installed with the two moving guide rods 22, so that the two moving guide rods 22 can effectively drive the moving die 23 to move back and forth. When the moving die 23 moves, the slider 27 at the bottom moves along the slide rail 26, and the moving die 23 also slides along the guiding slide rod 25, effectively ensuring the cooperation between the moving die 23 and the fixed die 24;

[0031] Between the bottom of the tank body 30 and the carrier 32, there is a pressure sensor 33; the pressure sensor 33 is connected to a controller 34; the controller 34 is connected to a vibration motor 35 through a wire; the vibration motor 35 is fixedly installed on the filling pipe 36.

[0032] In this embodiment, one end of the filling pipe 36 extends into the cavity of the fixed die 24, and the other end is hermetically connected to the bottom of the tank body 30.

[0033] By adopting the above technical solution, after the moving die 23 and the fixed die 24 are cooperated, the pressurizing tank 31 injects pressure into the top of the tank body 30 to realize the transmission of the molten metal inside the tank body 30. The pressure sensor 33 at the bottom of the tank body 30 effectively detects the transmitted metal. When it detects the transmission of metal, the pressure sensor 33 transmits the detected signal to the controller 34, and the controller 34 controls the vibration motor 35 to effectively vibrate the molten metal transmitted inside the filling pipe 36, avoiding the situation of bubbles existing in the molten metal. One end of the filling pipe 36 extends into the cavity of the fixed die 24 to effectively transmit the molten metal, ensuring the quality of the die-casting mold and improving the working efficiency of the die-casting processing equipment;

[0034] In this embodiment, a rectangular groove is formed at the top of the base 1, and a vibration assembly 4 is fitted and installed inside the base 1. The vibration assembly 4 includes a drive motor 40. A semi-circular gear 45 is fixedly installed on the output shaft of the drive motor 40. A sliding column 42 is arranged on one side of the semi-circular gear 45. A plurality of teeth 44 are integrally formed on the sliding column 42, and the teeth 44 are intermittently engaged with the semi-circular gear 45.

[0035] Furthermore, a spring 43 is arranged between the top of the sliding column 42 and the annular fixed support plate 41. The fixed support plate 41 is fixedly installed on the base 1 through a support rod.

[0036] By adopting the above technical solution, after the moving die 23 and the fixed die 24 are fitted together, the drive motor 40 drives the semi-circular gear 45 to rotate at a constant speed. When the semi-circular gear 45 is engaged with the teeth 44 on one side of the sliding column 42, the spring 43 between the top of the sliding column 42 and the fixed support plate 41 is compressed, and the sliding column 42 slides downward. When the semi-circular gear 45 is separated from the teeth 44 on one side of the sliding column 42, the top of the sliding column 42 rebounds and resets under the action of the spring 43. Due to the inertia of the spring 43, the top of the sliding column 42 contacts the bottom of the moving die 23, realizing the knocking on the moving die 23. In this way, when filling molten metal, it is ensured that the molten metal fully fills the mold cavity between the moving die 23 and the fixed die 24, ensuring that the die-casting mold will not be incomplete and ensuring the quality of the product.

[0037] The working principle of the present utility model is as follows: When in use, first, the electric push cylinder 21 installed on the fixed plate 20 drives the push block 28 to move back and forth. The push block 28 is fixedly installed with two moving guide rods 22, so that the two moving guide rods 22 can effectively drive the moving die 23 to move back and forth. When the moving die 23 moves, the bottom slider 27 moves along the slide rail 26, and the moving die 23 also slides along the guide slide rod 25, effectively ensuring the cooperation between the moving die 23 and the fixed die 24.

[0038] After the moving die 23 and the fixed die 24 are fitted together, the drive motor 40 drives the semi-circular gear 45 to rotate at a constant speed. When the semi-circular gear 45 is engaged with the teeth 44 on one side of the sliding column 42, the spring 43 between the top of the sliding column 42 and the fixed support plate 41 is compressed, and the sliding column 42 slides downward. When the semi-circular gear 45 is separated from the teeth 44 on one side of the sliding column 42, the top of the sliding column 42 rebounds and resets under the action of the spring 43. Due to the inertia of the spring 43, the top of the sliding column 42 contacts the bottom of the moving die 23, realizing the knocking on the moving die 23. In this way, when filling molten metal, it is ensured that the molten metal fully fills the mold cavity between the moving die 23 and the fixed die 24, ensuring that the die-casting mold will not be incomplete and ensuring the quality of the product.

[0039] After the moving die 23 and the fixed die 24 are cooperated to complete, the pressure tank 31 is used to inject pressure into the top of the tank body 30, so as to realize the transmission of the molten metal inside the tank body 30. The pressure sensor 33 at the bottom of the tank body 30 effectively detects the transmitted metal. When the metal transmission is detected, the pressure sensor 33 transmits the detected signal to the controller 34. The controller 34 realizes the control of the vibration motor 35, so as to effectively vibrate the molten metal transmitted inside the filling pipe 36, avoiding the situation of bubbles existing in the molten metal. One end of the filling pipe 36 extends into the cavity of the fixed die 24, realizing the effective transmission of the molten metal, ensuring the quality of the die-casting mold and improving the working efficiency of the die-casting processing equipment.
