Description

Technical Field

[0001] This application relates to the technical field of core molds, and particularly to an efficient core mold for casting. Background Art

[0002] A core mold is a mold used in the casting process for forming hollow parts or complex internal structures. The core mold is usually composed of a special core, which maintains its shape during the casting process until it is removed after casting is completed.

[0003] Currently, when a core mold is used for core casting, due to the irregular shape and variable structure of the cast core, when removing the cast core, workers need to carefully lift it from the mold groove of the lower mold base with the help of tools, and then transfer and store it. During this process, workers need to be extremely cautious. A slight carelessness may cause the core to be bumped and worn or leave marks on the contact part with the tool. Therefore, an efficient core mold for casting is designed to solve the above-mentioned problems. Summary of the Utility Model

[0004] To solve the problem, this application provides an efficient core mold for casting. By setting threaded rods and mounting frames in the fixed block and the mold groove, the mounting frame drives the bottom plate to rise, so that the bottom plate lifts the core die-cast in the mold groove, enabling the core to be directly taken out by workers and making the removal of the core more convenient.

[0005] An efficient core mold for casting provided by this application adopts the following technical solutions:

[0006] An efficient core mold for casting includes an upper mold base and a lower mold base. The lower end of the lower mold base is fixedly connected to a fixed block, a fixed groove is opened in the fixed block, a mold groove is opened in the upper part of the lower mold base, the mold groove is communicated with the fixed groove, the bottom of the mold groove is slidably connected to a bottom plate, the lower end of the bottom plate is fixedly connected to a mounting frame, and the lower end of the mounting frame is threadedly connected to a threaded rod. By rotating the threaded rod, the mounting frame is driven to rise or fall, so that the mounting frame drives the bottom plate to rise or fall, thereby pushing the core in the mold groove, enabling the core to directly expose from the mold groove, facilitating workers to take out the core and avoiding damage.

[0007] Preferably, the lower end of the threaded rod is fixedly connected to a mounting block, and a pulley is fixedly connected to the outer wall of the mounting block.

[0008] Preferably, a servo motor is fixedly connected to the lower end of the pulley, and the servo motor is fixed in the fixed groove. By starting the servo motor, the servo motor drives the pulley to rotate, thereby driving the threaded rod to rotate, achieving the control of the rise or fall of the bottom plate.

[0009] Preferably, a transmission belt is installed on the pulley, and the transmission belt is drivingly connected to the pulley.

[0010] Preferably, the installation frame is square, so that when the installation frame is driven by the threaded rod, it cannot rotate with the threaded rod, and the installation frame can only move up or down. The installation frame is slidably connected to the fixed groove.

[0011] Preferably, a control panel is installed on one side of the fixed block, and the control panel is electrically connected to the servo motor.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. In the present utility model, by providing the threaded rod and the installation frame in the fixed block and the die groove, after the upper die base and the lower die base are used to die-cast the sand core, the servo motor can be used to drive the threaded rod to rotate, so that the installation frame rises, and drives the bottom plate to rise, so that the bottom plate can lift the sand core die-cast in the die groove, so that the sand core can be directly taken out by the worker, making the removal of the sand core more convenient.

[0018] The following will Figures 1-3 further describe the present application in detail.

[0019] An embodiment of the present application discloses an efficient sand core mold for casting. Referring to Figures 1-3 , an efficient sand core mold for casting includes an upper die base 1 and a lower die base 2. As Figure 1 shown, the lower end of the lower die base 2 is fixedly connected to a fixed block 3, a fixed groove 31 is opened in the fixed block 3, a die groove 21 is opened in the upper part of the lower die base 2, and the die groove 21 communicates with the fixed groove 31;

[0020] By adopting the above technical solution, the bottom of the die cavity 21 is slidably connected to the bottom plate 4. The lower end of the bottom plate 4 is fixedly connected to the mounting frame 5, and the lower end of the mounting frame 5 is threadedly connected to the threaded rod 6. After the threaded rod 6 rotates, it drives the mounting frame 5 to rise or fall, so that the mounting frame 5 drives the bottom plate 4 to rise or fall, thereby enabling the bottom plate 4 to push the core in the die cavity 21, so that the core can be directly exposed from the die cavity 21, facilitating the workers to take out the core and avoiding damage.

[0021] By adopting the above technical solution, the lower end of the threaded rod 6 is fixedly connected to the mounting block, and the outer wall of the mounting block is fixedly connected to the pulley 7. A transmission belt 8 is installed on the two pulleys 7. When one side pulley 7 rotates, the pulley 7 drives the other side pulley 7 to rotate through the transmission belt 8; the lower end of the pulley 7 is fixedly connected to the servo motor 9, and the servo motor 9 is fixed in the fixed groove 31. By starting the servo motor 9, the servo motor 9 can drive the pulley 7 to rotate, thereby driving the threaded rod 6 to rotate, achieving the control of the rise or fall of the bottom plate 4.

[0022] By adopting the above technical solution, the mounting frame 5 is square, so that when the mounting frame 5 is driven by the threaded rod 6, it cannot rotate following the threaded rod 6, and the mounting frame 5 can only rise or fall, and the mounting frame 5 is slidably connected to the fixed groove 31.

[0023] By adopting the above technical solution, a control panel is installed on one side of the fixed block 3. The control panel is electrically connected to the servo motor 9. The control panel is a control device composed of a PLC controller and a display screen, which is a common control panel structure and is used to control the operation of the servo motor 9.

[0024] The implementation principle of an efficient core mold for casting in an embodiment of the present application is as follows: after the upper mold base 1 descends and fits with the lower mold base 2, sand is injected into the die cavity 21 for die casting. After die casting, the upper mold base 1 rises and separates from the lower mold base 2, and the mold is separated from the die cavity 21. Then, the control panel is used to drive the output shaft of the servo motor 9 to rotate, so that the servo motor 9 drives the mounting block to rotate. The mounting block drives the upper pulley 7 to rotate. Since the pulley 7 drives the other side pulley 7 to rotate through the transmission belt 8, the two pulleys 7 drive the threaded rod 6 above them to rotate. The threaded rod 6 drives the mounting frame 5 to move, so that the mounting frame 5 rises and pushes the upper bottom plate 4 to rise, and the bottom plate 4 pushes the core located in the die cavity 21 to rise. The core is slowly lifted by the bottom plate 4 and rises from the die cavity 21, and then the worker can directly take out the core.

[0025] After taking out, the servo motor 9 can be controlled again to drive the threaded rod 6 to rotate in the reverse direction, and drive the mounting frame 5 to descend, so that the mounting frame 5 drives the bottom plate 4 to move to the bottom of the die cavity 21 again to restore.
