Description

Technical Field

[0001] This application relates to the technical field of mold processing, and particularly relates to a portable automatic mold locking device. Background Art

[0002] Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the inner cavity of the mold. The mold is usually processed from an alloy with higher strength, and this process is somewhat similar to injection molding.

[0003] A die casting mold usually consists of a fixed mold and a movable mold. When die casting is performed, the movable mold is closed, and liquid metal is pressed into the mold cavity. After die casting is completed, the movable mold is opened, and the formed workpiece is taken out. During the die casting process, the clamping force between the fixed mold and the movable mold is a key factor determining the quality of the formed workpiece. However, when the existing mold locking device is used for a long time, due to the lack of an effective mold locking structure, it is prone to looseness, resulting in an unqualified clamping force between the fixed mold and the movable mold, which affects the quality of the die-cast formed workpiece.

[0004] Therefore, those skilled in the art have provided a portable automatic mold locking device to solve the problems raised in the above background art. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Such as Figure 1-Figure 3As shown in the figure, the present application discloses a portable automatic mold clamping device, which includes a fixed base 8, a moving mold 1 and a stationary mold 9. The stationary mold 9 is installed on the upper surface of the fixed base 8 to provide overall stability for the lower part of the device. Ring-shaped convex plates 5 are fixedly connected to the outside of both the moving mold 1 and the stationary mold 9. Four support plates 10 are fixedly connected to the outer edge of the fixed base 8, and the four support plates 10 are sequentially distributed in four directions on the outer edge of the fixed base 8. A side plate 7 is fixedly connected to the lower side of one side of the support plate 10. A support shaft 6 is rotatably connected to the upper surface of the side plate 7. A driven wheel 13 is fixedly connected to the top of the support shaft 6, which is convenient for providing support under the driven wheels 13 in four directions and ensuring the stable rotation of the four driven wheels 13. A belt 12 is sleeved on the outside of the four driven wheels 13, which is convenient for driving the belt 12 to rotate by the rotation of one of the driven wheels 13, so that the other three driven wheels 13 can also rotate synchronously. A driving motor 11 is installed on the lower surface of one of the side plates 7, and the output end of the driving motor 11 is fixed to the bottom of the corresponding support shaft 6. The driving motor 11 can drive one of the driven wheels 13 to rotate. A transmission gear 15 is fixedly connected to the upper surface of the driven wheel 13. A mold clamping mechanism is arranged between the driven wheel 13 and the transmission gear 15. By starting the driving motor 11 to drive the driven wheel 13 to cooperate with the belt 12, the four transmission gears 15 rotate synchronously, driving the mold clamping mechanisms in four directions to move horizontally, so as to realize mold clamping between the moving mold 1 and the stationary mold 9.

[0020] As Figure 1-Figure 3 shown in the figure, the mold clamping mechanism in this device includes a guide rail frame 14, a toothed plate 16 and a U-shaped locking plate 17. The guide rail frame 14 is sleeved on the top of the driven wheel 13, and one side of the guide rail frame 14 is fixedly connected to the outside of the toothed plate 16. The outside of one side of the guide rail frame 14 can move horizontally on the top of the support plate 10, which can not only provide support for the toothed plate 16, but also ensure the stability of the toothed plate 16 during horizontal movement. At the same time, the tooth side of the toothed plate 16 meshes with the outside of the transmission gear 15. The U-shaped locking plate 17 is fixed to the end of the toothed plate 16, which is convenient for limiting the annular convex plate 5 in time when the toothed plate 16 and the U-shaped locking plate 17 move horizontally driven by the rotation of the transmission gear 15.

[0021] As Figure 2 and Figure 3 shown in the figure, when the moving mold 1 and the stationary mold 9 are in the closed state in this device, the distance value between the two annular convex plates 5 is adapted to the height value of the inner cavity of the U-shaped locking plate 17, so that when the U-shaped locking plate 17 moves closer to the moving mold 1 and the stationary mold 9, the inner wall of the U-shaped locking plate 17 can move in a fitting manner outside the two annular convex plates 5 to realize the limitation of the annular convex plate 5.

[0022] As Figure 1As shown, on the upper surface of the fixed base 8 of the device, a support frame 4 is installed diagonally. In the middle above the support frame 4, a hydraulic cylinder 2 is installed, and the bottom of the hydraulic cylinder 2 is fixed to the upper surface of the moving mold 1. During use, by starting the hydraulic cylinder 2, the hydraulic cylinder 2 drives the moving mold 1 to move downward and closely fit the notch above the fixed mold 9. Then, molten liquid is injected into the mold cavities of the moving mold 1 and the hydraulic cylinder 2 through the pipe orifice to achieve mold processing.

[0023] As Figure 1 shown, at both corners of the upper surface of the moving mold 1, limiting rods 3 are fixedly connected, and the outside of the limiting rods 3 penetrates through the top wall of the support frame 4, facilitating the limitation of the moving mold 1 and ensuring the stability of the vertical up and down movement of the moving mold 1.

[0024] All standard parts used in the present utility model can be purchased from the market. Special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0025] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0026] The implementation principle of an embodiment of a portable automatic mold locking device in this application is as follows: During processing, start the hydraulic cylinder 2 to drive the moving mold 1 to move downward and fit the notch above the fixed mold 9. Then, by starting the driving motor 11, the output end of the driving motor 11 can drive one of the support shafts 6 to rotate. Then, the support shaft 6 drives the driven wheel 13 at the top to rotate. Thus, at this time, rotating the driven wheel 13 and cooperating with the belt 12 can synchronously drive the synchronous rotation of the other three driven wheels 13. Immediately afterwards, the four rotating driven wheels 13 synchronously drive the toothed plate 16 to move horizontally. Then, the four toothed plates 16 drive the four U-shaped locking plates 17 to approach the moving mold 1 and the fixed mold 9 simultaneously, so that the inner walls of the U-shaped locking plates 17 are in contact with the outside of the two annular convex plates 5, limiting the two annular convex plates 5 in four directions at the same time, facilitating automatic mold locking after the moving mold 1 and the fixed mold 9 are closed, and ensuring an effective clamping force between the moving mold 1 and the fixed mold 9.
