Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically a high-efficiency metal die casting mold. Background Technology

[0002] Metal die casting is a metal forming technology widely used in manufacturing. It involves rapidly injecting molten metal into a mold cavity under high pressure to form castings with complex shapes and precise dimensions. Existing metal die casting mold designs play a crucial role in the production of various metal products.

[0003] Existing technologies disclose several utility model patents in the field of die-casting mold processing. Among them, utility model patent application number 202122138540.4 discloses a high-efficiency metal die-casting mold, including a metal die-casting mold body. The top of the metal die-casting mold body has a metal die-casting groove, and the bottom inner wall of the metal die-casting groove has several ejection holes. An ejection lifting seat is located below the metal die-casting mold body, and a fixed base is located at the bottom of the ejection lifting seat. Several ejection rods are fixedly connected to the top of the ejection lifting seat. The top of the ejection lifting seat and the bottom of the metal die-casting mold body are connected by several tension springs. The top of the fixed base and the bottom of the metal die-casting mold body are connected by four supporting fixed prisms. This utility model, a high-efficiency metal die-casting mold, belongs to the field of die-casting mold technology. By driving the ejection rods upward, the processed part located in the metal die-casting groove is moved upward, facilitating the removal of the processed part. The operation steps are simple and convenient.

[0004] However, the above method still has the following drawbacks in actual use: although it can eject the internally processed workpiece, some impurities may be introduced when the metal is injected into the mold under high pressure. These impurities may accumulate in the ejection hole and metal die-casting groove of the mold when the workpiece is ejected, resulting in a decrease in the cleanliness of the mold and the need to clean the mold, thereby reducing the efficiency of subsequent work. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency metal die-casting mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency metal die-casting mold, comprising a base, a lower mold fixedly connected above the base, a workpiece groove being engaged within the lower mold, an upper mold overlapping the lower mold, a movable plate connected outside the workpiece groove, a locking structure slidably connected within the lower mold, the locking structure overlapping the movable plate, a pop-out structure provided on the back of the lower mold, the pop-out structure being connected to the movable plate, the pop-out structure comprising a fixed post, an auxiliary plate, and a ratchet plate, a sliding plate slidably connected outside the fixed post, a spring being sleeved on the fixed post, a baffle rotatably connected within the auxiliary plate, and a coil spring being provided within the auxiliary plate.

[0007] As a further preferred embodiment of this technical solution, the movable plate is slidably connected inside the lower mold, the fixed column is fixedly connected to the back of the lower mold, and the auxiliary plate is fixedly connected to the back of the lower mold.

[0008] As a further preferred embodiment of this technical solution, the ratchet plate is fixedly connected to one side of the moving plate, the baffle plate overlaps with the ratchet plate, and the overlapping plate overlaps with one side of the moving plate.

[0009] As a further preferred embodiment of this technical solution, the mounting plate is connected to the lower mold via a spring, and the baffle is connected to the auxiliary plate via a coil spring.

[0010] As a further preferred embodiment of this technical solution, the locking structure includes a limiting plate and a threaded rod, the threaded rod being rotatably connected to the front side of the lower mold, and the limiting plate being slidably connected inside the lower mold.

[0011] As a further preferred embodiment of this technical solution, the limiting plate overlaps with the moving plate, and the threaded rod is externally threaded with a sleeve plate.

[0012] As a further preferred embodiment of this technical solution, one end of the threaded rod is fixedly connected to a turntable, and the sleeve is connected to the limiting plate.

[0013] This utility model provides a high-efficiency metal die-casting mold, which has the following beneficial effects:

[0014] (1) This utility model sets up a workpiece groove, a moving plate and a pop-out structure. The workpiece groove is connected to the lower mold by the moving plate. When the moving plate moves, it will contact the mounting plate. The mounting plate will slide on the surface of the fixed column. When the mounting plate slides, it will cause the spring to deform. When the baffle contacts the ratchet plate, it will rotate in the auxiliary plate. When the baffle rotates, it will cause the coil spring to deform. When the moving plate moves to the appropriate position, the baffle will overlap with the ratchet plate through the action of the coil spring. This allows the die-casting mold to automatically pop out of the lower mold through the cooperation between the spring, the baffle and the ratchet plate. This makes it easy to remove or clean the workpiece in the workpiece groove. It also makes it easy to process other workpieces. This ensures the flexibility of the die-casting mold.

[0015] (2) By setting a locking structure, the screw rod is rotated by the turntable, and the sleeve plate moves on the surface of the screw rod. The sleeve plate will drive the limiting plate and the moving plate to overlap, thereby locking the position of the workpiece groove and preventing the workpiece groove from falling off when affected by external force.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown, in this embodiment, a high-efficiency metal die-casting mold includes a base 1, a lower mold 2 fixedly connected above the base 1, a workpiece groove 4 clamped inside the lower mold 2, an upper mold 3 overlapping the lower mold 2, a movable plate 6 connected outside the workpiece groove 4, a locking structure 5 slidably connected inside the lower mold 2, the locking structure 5 overlapping the movable plate 6, a pop-out structure 7 provided on the back of the lower mold 2, the pop-out structure 7 connected to the movable plate 6, the pop-out structure 7 includes a fixed post 701, an auxiliary plate 704 and a ratchet plate 707, a mounting plate 702 slidably connected outside the fixed post 701, a spring 703 sleeved on the fixed post 701, a baffle 705 rotatably connected inside the auxiliary plate 704, and a coil spring 706 provided inside the auxiliary plate 704.

[0024] like Figure 1 and Figure 4 As shown, the movable plate 6 is slidably connected inside the lower mold 2, the fixed column 701 is fixedly connected to the back of the lower mold 2, the auxiliary plate 704 is fixedly connected to the back of the lower mold 2, the ratchet plate 707 is fixedly connected to one side of the movable plate 6, the baffle 705 overlaps with the ratchet plate 707, the overlapping plate 702 overlaps with one side of the movable plate 6, the overlapping plate 702 is connected to the lower mold 2 by the spring 703, and the baffle 705 is connected inside the auxiliary plate 704 by the coil spring 706.

[0025] By setting the lower mold 2, when the turntable 503 drives the threaded rod 502 to rotate, the sleeve 504 will move on the surface of the threaded rod 502, and the sleeve 504 will drive the limiting plate 501 to slide inside the lower mold 2, so that the lower mold 2 plays a certain guiding role in the movement of the limiting plate 501, and avoids the limiting plate 501 from getting stuck when moving.

[0026] like Figure 5 As shown, the locking structure 5 includes a limiting plate 501 and a threaded rod 502. The threaded rod 502 is rotatably connected to the front of the lower mold 2, and the limiting plate 501 is slidably connected inside the lower mold 2. The limiting plate 501 overlaps with the moving plate 6. The threaded rod 502 is externally threaded with a sleeve plate 504. One end of the threaded rod 502 is fixedly connected to a turntable 503, and the sleeve plate 504 is connected to the limiting plate 501.

[0027] By setting up a fixed column 701, a mounting plate 702, and a spring 703, when the workpiece groove 4 applies a pushing force to the mounting plate 702 through the moving plate 6, the mounting plate 702 will cause the spring 703 to deform as it moves on the surface of the fixed column 701. The spring 703 can apply a popping force to the workpiece groove 4, preventing the workpiece groove 4 from getting stuck when popping out, and also providing a certain support for the movement of the workpiece groove 4.

[0028] This utility model provides a high-efficiency metal die-casting mold, the specific working principle of which is as follows:

[0029] When the die-casting mold is in use, the workpiece groove 4 can be connected to the lower mold 2 by the moving plate 6. When the moving plate 6 moves, it will contact the mounting plate 702. The mounting plate 702 will slide on the surface of the fixed column 701. When the mounting plate 702 slides, it will cause the spring 703 to deform. When the baffle 705 contacts the ratchet plate 707, it will rotate in the auxiliary plate 704. When the baffle 705 rotates, it will cause the coil spring 706 to deform. When the moving plate 6 moves to the appropriate position, the baffle 705 will overlap with the ratchet plate 707 through the action of the coil spring 706. Then, the turntable 503 will drive the threaded rod 502 to rotate. The sleeve plate 504 will move on the surface of the threaded rod 502. The sleeve plate 504 will drive the limiting plate 501 to overlap with the moving plate 6.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
