Description

Technical Field

[0001] This utility model relates to a differential pressure casting machine, specifically a differential pressure casting machine combining a column and a synchronous guide column, belonging to the technical field of casting equipment. Background Technology

[0002] Differential pressure casting is a casting process that extends from low-pressure casting. Compared with conventional low-pressure casting, the casting mold needs to be sealed in a tank, which is filled with compressed air and pressurized to form the casting under a certain pressure atmosphere. Under higher pressure, the aluminum liquid crystallizes and forms castings with higher density than low-pressure casting.

[0003] Traditional differential pressure casting machines almost always use guide pillars running from top to bottom. However, the section from the worktable to the base is used to house the holding furnace, and the worktable doesn't require lifting. This means the guide pillars in this section don't actually serve a lifting or guiding function. Using guide pillars in this section also lengthens the entire guide pillar, significantly increasing the precision requirements for its machining and raising equipment costs. Furthermore, the guide pillars have relatively low rigidity and poor stability, ultimately leading to a low casting yield. Due to issues like easy pressure loss and insufficient clamping force, the performance of the castings produced is not significantly improved compared to low-pressure casting.

[0004] Therefore, this utility model was proposed. Utility Model Content

[0005] In view of the above-mentioned technical problems of the prior art, the purpose of this utility model is to provide a differential pressure casting machine with a combination of column and synchronous guide column. The worktable and the base are connected by a column, which greatly improves the rigidity of the equipment and is easy to install. The precision requirements of the guide column are also greatly reduced, which reduces the cost to a certain extent. It also solves many technical problems of differential pressure casting such as unstable filling and air intake, insufficient clamping force, and asynchronous mold opening.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A differential pressure casting machine combining a column and a synchronous guide column includes, from top to bottom, an upper template, a moving template, a worktable, and a base. The base and the worktable are connected by a frame column, and the worktable and the upper template are connected by a synchronous guide column. The moving template is inserted into the synchronous guide column and moves up and down along the synchronous guide column.

[0007] The frame columns consist of four pillars, which are located at the four corners of the base and the workbench. The synchronous guide columns also consist of four pillars, which are located at the four corners of the workbench and the upper template.

[0008] The synchronization guide post is equipped with a synchronization mechanism.

[0009] The synchronization mechanism includes rotating shafts installed on both sides of the moving template, with rotating gears installed at both ends of the rotating shafts, and the synchronization guide post having a plurality of tooth grooves that mesh with the rotating gears.

[0010] The moving template is provided with a gear seat, and the gear seat is provided with an adjustment device and a clamping device. After the rotating gear is installed in the gear seat, its position is adjusted by the adjustment device and clamped by the clamping device.

[0011] The adjustment device includes an adjustment block located outside the gear seat, and an adjustment screw is provided on the adjustment block.

[0012] A differential pressure locking mechanism is provided below the upper template. The differential pressure locking mechanism includes a hydraulic cylinder and a differential pressure locking rod installed on the moving template. A piston rod is provided inside the hydraulic cylinder, and a locking tongue is provided at the end of the piston rod. The differential pressure locking rod is provided with several locking grooves, and the locking tongue enters the locking grooves to achieve locking.

[0013] A heat preservation furnace, an electric quick-connect mechanism, and an air intake mechanism are provided between the base and the worktable, and the heat preservation furnace, electric quick-connect mechanism, and air intake mechanism work together.

[0014] A tank device and an air intake isolation device are provided between the moving template and the workbench, and the tank device and the air intake isolation device work together.

[0015] A cooling water tank is provided on the outside of the frame column, and a product receiving mechanism is provided inside the cooling water tank.

[0016] The differential pressure casting machine combining the column and synchronous guide column of this utility model has the following beneficial effects: 1. This utility model connects the base and the worktable through frame columns, and connects the worktable and the upper template through synchronous guide columns. The combination of frame columns and synchronous guide columns satisfies the lifting requirements of the moving template on the synchronous guide columns, while shortening the length of the synchronous guide columns and greatly reducing their precision requirements. In addition, the frame columns are easier to install and have much higher rigidity than the guide columns, improving the rigidity of the entire equipment. The frame columns support the worktable, reducing air leakage problems caused by insufficient rigidity, thus improving the stability of the differential pressure casting machine.

[0017] 2. The moving template in this utility model is equipped with a synchronization mechanism. By designing tooth grooves on the synchronization guide post and cooperating with the synchronization gears installed on the left and right sides of the moving template, the synchronization of the four corners of the template is improved when the moving template opens, and the problems such as casting damage caused by asynchronous opening and closing of the template are reduced.

[0018] 3. The top of this utility model is equipped with two sets of differential pressure lock structures, which solves the problem of the original equipment being unable to be compressed when the tank is filled with air, resulting in air leakage.

[0019] 4. The tank device in this utility model is automatically connected to the air intake mechanism of the heat preservation furnace. The air intake pipe of the tank is connected through the air intake isolation device connected to the moving template. After the moving template is lowered and closed, the air intake pipe can realize the automatic connection function. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0022] like Figure 1-8As shown, the differential pressure casting machine of this utility model, which combines a column and a synchronous guide column, includes, from top to bottom, an upper template 1, a moving template 2, a worktable 3, and a base 4. A heat preservation furnace 21, an electric quick-connect mechanism 22, and an air intake mechanism 23 are provided between the base 4 and the worktable 3, and these components work together. A tank device 24 and an air intake isolation device 25 are provided between the moving template 2 and the worktable 3, and these components work together. The tank device 24 is automatically connected to the heat preservation furnace 21 via the air intake mechanism 23. The air intake pipe of the tank device 24 is connected via the air intake isolation device 25 connected to the moving template 2. After the moving template 2 descends and closes, the air intake pipe can automatically connect.

[0023] Furthermore, in this invention, the base 4 and the worktable 3 are connected by four frame columns 5, located at the four corners of both the base 4 and the worktable 3. A cooling water tank 25 is located on the outer side of each frame column 5, and a product receiving mechanism 26 is located inside the cooling water tank 25. The worktable 3 and the upper template 1 are connected by four synchronous guide columns 6, located at the four corners of both the worktable 3 and the upper template 1. The moving template 2 is inserted into the synchronous guide columns 6 and moves up and down along them. This frame structure, combining the frame columns 5 and the synchronous guide columns 6, allows the frame columns 5 to support the worktable 3, improving the overall rigidity of the equipment, reducing overall stability during movement, and minimizing air leakage caused by insufficient rigidity. The use of synchronous guide columns in the moving template increases the positioning accuracy of the moving template and improves the repeatability of the opening and closing process of the upper and lower templates.

[0024] Furthermore, the synchronous guide post 6 in this invention is equipped with a synchronous mechanism 7. The synchronous mechanism 7 includes rotating shafts 8 installed on both sides of the moving template 2. Rotating gears 9 are installed at both ends of the rotating shafts 8. The synchronous guide post 6 is provided with several tooth grooves 10, which mesh with the rotating gears 9. The moving template 2 is provided with a gear seat 11, which is provided with an adjustment device and a clamping device 14. The adjustment device includes adjustment blocks 12 located on both sides of the gear seat 11, and adjustment screws 13 are provided at both ends of the adjustment blocks 12. The clamping device 14 can be a clamping screw. Screw holes are provided on both sides of the gear seat 11. The clamping screw is inserted into the screw holes. After the rotating gear 9 is installed in the gear seat 11, the position of the rotating gear 9 and the tooth grooves 10 is adjusted by adjusting the screws 13. Then, the clamping screw installed on the moving template 2 is pressed down to clamp the gear seat 11, thereby clamping the rotating gear 9. The synchronization mechanism 7 improves the synchronization of the four corners of the template when the moving template 2 opens, reducing problems such as casting damage caused by asynchronous opening and closing of the template.

[0025] Furthermore, a differential pressure locking mechanism is provided below the upper template 1 in this utility model. The differential pressure locking mechanism includes a hydraulic cylinder 16 and a differential pressure locking rod 17 installed on the moving template 2. A piston rod 18 is provided inside the hydraulic cylinder 16, and a locking tongue 19 is provided at the end of the piston rod 18. Several locking grooves 20 are provided on the differential pressure locking rod 17, and the locking tongue 19 enters the locking grooves 20 to achieve locking. The double differential pressure lock type tank locking device seals the tank with a mold and uses a wedge block and the inclined surface of the differential pressure locking rod to press it. Two sets of differential pressure locking structures are set on the top of the equipment, which solves the problem of the original equipment being unable to press tightly when the tank is filled with air, resulting in air leakage. At the same time, the four wedge blocks reduce the force on the locking mold and avoid the problem of severe wear of the wedge blocks when the equipment is used frequently.

[0026] This utility model of a differential pressure casting machine combining a vertical column and a synchronous guide column greatly improves the rigidity of the equipment, simplifies installation, significantly reduces the precision requirements of the guide column, reduces costs to a certain extent, and solves many technical problems in differential pressure casting such as unstable filling and air intake, insufficient clamping force, and asynchronous mold opening.

[0027] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
