Description
Technical Field
[0001] The utility model belongs to the field of die-casting devices, and particularly relates to a deviation rectifying device for die-casting forming of hardware parts. Background Technique
[0002] A hardware part die-casting device is a precision casting device that uses high pressure to force molten metal into a metal mold with a complex shape. Die-casting, also known as pressure casting, is mainly characterized by high pressure and high speed. During die-casting, the molten alloy is poured into the pressure chamber, filled into the cavity of the steel mold at high speed, and solidified under pressure to form a casting with a specific shape and size.
[0003] In the die-casting process, after the molten metal is injected into the mold, it needs to be demolded and the mold needs to be reassembled. After long-term use, the mold may be misaligned due to wear or improper adjustment, affecting the accuracy of die-cast hardware parts. Moreover, after taking out the die-cast product, it is necessary to manually support the spraying device for releasing agent to spray between the molds, resulting in low work efficiency.
[0004] Therefore, a deviation rectifying device for die-casting forming of hardware parts is proposed, with a deviation rectifying and positioning structure and a structure for automatically spraying releasing agent, which can quickly rectify and fit the mold and perform rapid spraying work. Content of the Utility Model
[0005] In order to overcome the problems that the existing die-casting device mold lacks a positioning and deviation rectifying structure and the spraying of releasing agent on the mold is relatively cumbersome.
[0006] The technical solution of the utility model is: a deviation rectifying device for die-casting forming of hardware parts, including a first fixing plate; a fixed mold is fixedly connected to the rear end of the first fixing plate, and a deviation rectifying component is arranged on the fixed mold. The deviation rectifying component includes a first ear plate, a second ear plate, and a limiting column; the first ear plates are fixedly connected to the upper and lower ends of the fixed mold, the inner wall of the first ear plate is fixedly connected with the limiting column, the outer wall of the limiting column is slidably provided with the second ear plate, the rear ends of the two limiting columns are commonly fixedly connected with a second fixing plate, a liquid guide pipe is fixedly connected to the front end of the first fixing plate in a through manner, the liquid guide pipe and the fixed mold are connected in a through manner, a limiting frame is fixedly connected to the front end of the first fixing plate, a pressure injection mechanism is arranged in front of the limiting frame, the output end of the pressure injection mechanism passes through the limiting frame and extends to the front part of the inner wall of the liquid guide pipe, a liquid injection groove is penetrated and opened on the upper part of the arc-shaped outer wall of the liquid guide pipe, and a liquid spraying adjustment component is arranged on the fixed mold.
[0007] Preferably, the molten metal is placed in the injection tank, and then the injection mechanism is activated to push the molten metal to the fixed mold and the alignment correction component for die-casting work. The cooling block on the alignment correction component is used to quickly cool the molten metal. Then, the air cylinder is activated to drive the alignment correction component to perform the blanking work. The die-cast product is taken out by using a clamping tool. At the same time, when the alignment correction component moves, it will drive the liquid spraying and adjusting component to spray liquid on the mold cavities of the fixed mold and the moving mold, which facilitates the quick removal of the die-cast product in the next work. By setting the alignment correction component, the problem that errors occur between the molds, resulting in unqualified die-cast products, can be solved.
[0008] Preferably, the alignment correction component includes a moving mold, a cooling block, and a heat conducting column. At one end where the two second ear plates are close to each other, a moving mold is fixedly connected. At the rear end of the moving mold, two cooling blocks are fixedly connected. On the outer walls of the left and right ends of the moving mold, heat conducting columns are fixedly connected. The two heat conducting columns and the two cooling blocks are connected to each other. When the moving mold moves, the second ear plate on the moving mold slides on the limit column, which can limit the movement track of the moving mold, thereby preventing the problem that the molds are not aligned accurately during subsequent die-casting work, resulting in unqualified die-cast products. When die-casting work needs to be carried out, by activating the cooling block, the cooling block can cool the moving mold through the heat conducting column, which is convenient for quickly cooling and forming the molten metal during the subsequent die-casting work.
[0009] Preferably, a cylinder is fixedly connected to the front end of the second fixed plate. The front end of the telescopic rod of the cylinder is fixedly connected with a connecting block, and the front end of the connecting block is fixedly connected to the rear end of the moving mold. By driving the moving mold to move back and forth through the telescopic rod of the cylinder, the work of pressing the mold and blanking can be carried out.
[0010] Preferably, the liquid spraying and adjusting component includes a third ear plate, a first cylinder, a second rotating arm, and a fixing piece. A third ear plate is fixedly connected to the right end of the fixed mold. A first cylinder is rotatably arranged on the third ear plate. Two fixing pieces are fixedly connected to the outer wall of the first cylinder. One end where the two fixing pieces are close to each other fits with the upper and lower ends of the third ear plate.

When the telescopic rod of the cylinder drives the moving mold to move backward, the first rotating arm rotates on the fourth ear plate. When the left end of the first rotating arm contacts the trigger, the circulation pipe will spray the release agent.
[0012] Preferably, the liquid spraying and adjusting assembly includes a circulation pipe, a spray head, a liquid injection pipe and a motor; a circulation pipe is rotatably arranged at one end of two second rotating arms close to each other, a liquid injection pipe is fixedly connected to the outer wall of the circulation pipe in a penetrating manner, evenly distributed spray heads are fixedly connected to the outer wall of the circulation pipe in a penetrating manner, a motor is fixedly connected to the upper end of the second rotating arm above the third ear plate, and the lower end of the output shaft of the motor passes through the second rotating arm and is fixedly connected to the upper end of the circulation pipe. By connecting the liquid injection pipe to the liquid output device of the demolding machine, when the moving mold moves backward, the first rotating arm pulls the second rotating arm to rotate in the direction close to the right end of the moving mold, so that the spray heads on the circulation pipe are aligned with the mold cavities of the fixed mold. When the moving mold continues to move backward, the left end of the first rotating arm triggers the trigger, so that the spray heads start to work. Then, the release agent is sprayed on the mold cavities of the fixed mold after demolding through the spray heads. Then, the motor is started, and the output shaft of the motor drives the circulation pipe to rotate between the two second rotating arms, and the spray heads are aligned with the mold cavities on the moving mold for spraying work.
[0013] Preferably, the rotation angle of the circulation pipe on the two second rotating arms is 90 degrees. By setting the angle range, the behavior of the output shaft of the motor driving the circulation pipe to rotate and winding the pipes connected to the liquid injection pipe on the circulation pipe is prevented.
[0014] The beneficial effects of the present utility model are as follows:
[0015] 1. When the moving mold moves backward, the first rotating arm pulls the second rotating arm to rotate in the direction close to the right end of the moving mold, so that the spray heads on the circulation pipe are aligned with the mold cavities of the fixed mold. Then, the left end of the first rotating arm triggers the trigger through the movement of the moving mold, so that the spray heads start to work.

Then, the motor is started, and the output shaft of the motor drives the circulation pipe to rotate between the two second rotating arms, and the spray heads are aligned with the mold cavities on the moving mold for spraying work, solving the problem that the process of spraying the mold is relatively cumbersome.
[0016] 2.

[0017] 3. When die-casting work needs to be carried out, by turning on the refrigerating block, the refrigerating block can cool the moving die through the heat-conducting column, which is convenient for quickly cooling and forming the molten metal during the subsequent die-casting work.

[0027] When working, first, by turning on the refrigeration block 105, the refrigeration block 105 can cool the moving mold 103 through the heat conduction column 106.
