Specific implementation manner

[0031] 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 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.

[0032] Referring to Figure 1 , an embodiment provided by the present invention: A die-casting forming device for a compact ceramic package housing, including a bottom plate 1, a mold 2 is arranged on the upper surface of the bottom plate 1, a lifting cylinder 3 is fixedly connected to the upper surface of the bottom plate 1, the upper end of the lifting cylinder 3 is fixedly connected to a pressing material box 4, a hydraulic cylinder is arranged at the upper end inside the pressing material box 4, the bottom output end of the hydraulic cylinder is fixedly connected to a pressing plate. There is a feeding port (not directly shown in the figure) at the rear side of the pressing material box 4. When the hydraulic cylinder is started, it can drive the pressing plate to move downward to extrude the raw materials in the pressing material box 4, so that the raw materials are discharged through the discharge pipe 5. The bottom surface of the pressing material box 4 is fixedly connected to the discharge pipe 5, and a solenoid valve is fixedly connected to the outside of the discharge pipe 5 to control the opening and closing of the discharge pipe 5. When the lifting cylinder 3 is started, it can drive the pressing material box 4 to perform a linear motion in the up and down direction, so that the discharge pipe 5 can be docked with the feeding hopper 6 arranged below.

[0033] Referring to Figures 1-3, a feed hopper 6 is fixedly connected to the upper surface of the mold 2. The interior of the feed hopper 6 is in communication with the interior of the mold 2. The feed hopper 6 is arranged in an inverted hopper-shaped structure. A cross bar 7 is fixedly connected inside the feed hopper 6. An elastic member 8 is fixedly connected to the upper surface of the cross bar 7. The upper end of the elastic member 8 is fixedly connected to a sealing plate 9. When the sealing plate 9 is forced to move downward, it can squeeze the elastic member 8, causing the elastic member 8 to compress and generate elastic potential energy. When the force on the sealing plate 9 is released, the sealing plate 9 can move upward and reset under the action of the elastic potential energy of the elastic member 8. The size of the sealing plate 9 is adapted to the size of the upper end of the feed hopper 6. When the discharge pipe 5 moves downward, it can squeeze the sealing plate 9, causing the sealing plate 9 to move downward, thereby opening the upper end of the feed hopper 6. At this time, a gap is generated between the sealing plate 9 and the inner wall of the feed hopper 6, and the raw material can flow downward through the gap and then enter the interior of the mold 2. A sealing unit is arranged on the upper surface of the feed hopper 6. The sealing unit includes a fixed pipe 91. The fixed pipe 91 is fixedly connected to the upper surface of the feed hopper 6. A rubber ring 92 is fixedly connected inside the fixed pipe 91. Both the upper and lower ends of the inner wall of the rubber ring 92 are arranged in a chamfered shape. The inner wall of the rubber ring 92 fits with the outer wall of the sealing plate 9. In the initial state, the sealing plate 9 is located inside the rubber ring 92 and can squeeze the rubber ring 92, thereby sealing the interior of the fixed pipe 91 and performing a pressure holding operation on the interior of the mold 2 to ensure that the ceramic powder is fully filled in the mold 2 and reaches the required density.

[0034] A moving unit is arranged inside the discharge pipe 5. The moving unit includes a fixed rod 101. The fixed rod 101 is fixedly connected inside the discharge pipe 5. When the discharge pipe 5 moves, it can drive the fixed rod 101 to move synchronously. The bottom end of the fixed rod 101 is fixedly connected to a connecting rod 102. The bottom end of the connecting rod 102 is fixedly connected to a moving cone 103. The bottom surface size of the moving cone 103 is the same as the size of the sealing plate 9. The cross-section of the moving cone 103 is arranged in an isosceles triangle structure. When the fixed rod 101 moves, it can drive the moving cone 103 to move synchronously through the connecting rod 102. The moving cone 103 is located below the discharge pipe 5. When the discharge pipe 5 moves downward, the moving cone 103 will contact the sealing plate 9 first and squeeze the sealing plate 9, causing the sealing plate 9 to move downward and opening the internal space of the feed hopper 6. Subsequently, the solenoid valve can be activated to open the discharge pipe 5, enabling the raw material to flow downward under the action of the pressing plate and enter the interior of the mold 2. When the raw material passes through the moving cone 103, it will flow along the inclined surface of the moving cone 103 to the outside of the sealing plate 9, preventing the raw material from remaining and accumulating outside the sealing plate 9, which may affect the sealing effect of the feed hopper 6 and further affect the pressure holding effect on the interior of the mold 2.

[0035] Refer to Figures 4-5, a limiting groove 11 is formed on the upper surface of the bottom plate 1, and the bottom end of the mold 2 is inserted into the inside of the limiting groove 11. After the mold 2 is inserted into the inside of the limiting groove 11, it can be limited by the inner wall of the limiting groove 11, so that the feed hopper 6 is automatically aligned with the discharge pipe 5, avoiding deviation caused by manual alignment, so that the discharge pipe 5 cannot be aligned with the feed hopper 6. An inclined groove 12 is formed on the surface of the right inner wall of the limiting groove 11. After the mold 2 is filled with materials, the mold 2 can be pushed to move to the right, so that the mold 2 slides to the right along the inclined surface of the inclined groove 12 and leaves the lower part of the pressing material box 4, so that the next mold 2 can move to the lower part of the pressing material box 4 for die casting, improving the use efficiency of the mold 2 and accelerating the production efficiency of the product. A through groove 13 is formed on the left side of the inner bottom surface of the inclined groove 12. An L-shaped fixing frame 14 is fixedly connected to the bottom surface of the bottom plate 1. An electric push rod 15 is fixedly connected to the inner bottom surface of the L-shaped fixing frame 14. The upper end of the electric push rod 15 is fixedly connected with a limiting plate 16. The limiting plate 16 is inserted into the inside of the through groove 13. When the electric push rod 15 is started, it can drive the limiting plate 16 to perform a linear motion in the up and down directions. In the initial state, the left surface of the limiting plate 16 is in contact with the right surface of the mold 2, and the mold 2 located inside the limiting groove 11 can be limited to prevent the mold 2 from shifting in the left and right directions. After die casting is completed inside the mold 2, the electric push rod 15 can be started to drive the limiting plate 16 to move downward to quickly release the limit on the mold 2, so that the mold 2 can directly slide to the right, avoiding the need to lift the mold 2 filled with raw materials before the mold 2 can be taken and moved, reducing the labor intensity of the staff.

[0036] Working principle: After the mold 2 is moved and inserted into the inside of the limiting groove 11, the lifting cylinder 3 is started to drive the pressing material box 4 to move downward, so that the discharge pipe 5 is inserted into the inside of the fixed pipe 91, and the moving cone 103 moves downward to squeeze the sealing plate 9, so that the sealing plate 9 moves downward to open the feed hopper 6. Then the solenoid valve is started to open the discharge pipe 5, and the hydraulic cylinder is started to drive the pressing plate to move downward to squeeze the raw materials inside the pressing material box 4, so that the raw materials enter the inside of the mold 2 through the gap between the sealing plate 9 and the inner wall of the feed hopper 6. When the raw materials pass through the moving cone 103, they can flow downward along the inclined surface of the moving cone 103, avoiding the raw materials remaining and accumulating on the sealing plate 9, which may affect the pressure holding effect inside the mold 2. After the inside of the mold 2 is filled, the lifting cylinder 3 is started to drive the pressing material box 4 and the discharge pipe 5 to move upward, releasing the extrusion on the sealing plate 9, so that the sealing plate 9 moves upward and resets under the elastic potential energy of the elastic member 8, enters the inside of the fixed pipe 91, and squeezes the rubber ring 92 to realize the sealing treatment of the inside of the fixed pipe 91 and the feed hopper 6, and then automatically completes the pressure holding operation inside the mold 2, without the need to keep pressure on a set of molds 2 from die casting to forming, improving the working efficiency.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
