Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] In this technical solution, a brake pump forming mold includes a base plate 1 and four guide pillars 2. The bottom ends of the four guide pillars 2 are respectively installed at the four corners of the upper end of the base plate 1. A top plate 3 is installed at the top of the four guide pillars 2. Two first cylinders 4 are connected to the center of both sides of the top plate 3. A top mold 5 is connected to the telescopic ends of the two first cylinders 4. The top mold 5 is movably fitted on the upper end of the four guide pillars 2 on both sides. Two second cylinders 6 are installed at the center of both sides of the upper end of the base plate 1. A bottom mold 7 is installed on the telescopic ends of the two second cylinders 6. The bottom mold 7 is movably fitted on the upper end of the four guide pillars 2 on both sides. A pushing and unloading structure is connected to the lower end of the bottom mold 7. The pushing and unloading structure includes two mounting sleeves 8, two feeding sleeves 9, an air pump 10, an air distribution pipe 11, two actuating rods 12, and a downward air supply component.

[0024] Two mounting sleeves 8 are fixedly embedded on both sides of the lower end of the bottom mold 7. The bottom ends of two feeding sleeves 9 are respectively installed on both sides of the upper end of the base plate 1, and the top ends are respectively movably embedded in the two mounting sleeves 8. The air pump 10 is fixedly installed at the center of the upper end of the base plate 1. The bottom end of the air distribution pipe 11 is connected to the air outlet of the air pump 10, and the other end is connected to the center of the side wall of the two feeding sleeves 9. Two actuating rods 12 are respectively installed on both sides of the lower end of the bottom mold 7. The downward air supply assembly is located in the two feeding sleeves 9.

[0025] In this technical solution, during the molding process of the brake pump, the operator, according to the processing requirements, mounts the designated top mold 5 and bottom mold 7 onto the upper ends of four guide pillars 2, and connects them to two first cylinders 4 and two second cylinders 6. Then, the top mold 5 is connected to the feeding system, and the first cylinders 4 are driven to push the bottom mold 7 into position. The second cylinders 6 are then driven to make the top mold 5 and bottom mold 7 fit together. Subsequently, the feeding system injects raw material between the top mold 5 and bottom mold 7 for cooling and molding. After cooling and molding are completed, the first… Cylinder 4 and the second cylinder 6 retract synchronously. When the bottom mold 7 moves, the top of the feeding sleeve 9 located in the mounting sleeve 8 extends to mechanically unload the material in the bottom mold 7. At the same time, the air pump 10 at the top of the base plate 1 works to pressurize the gas and deliver it to the two feeding sleeves 9 through the air distribution pipe 11. When the actuating rods 12 on both sides of the lower end of the bottom mold 7 come into contact with the downward air delivery component, the feeding sleeves 9 and the air distribution pipe 11 are connected. The high-pressure gas delivered by the feeding sleeves 9 completely separates the molded product from the bottom mold 7, thus realizing the unloading and delivery of the product.

[0026] In some technical solutions, reference Figure 1 The downward air supply assembly includes two operating slots 13, two sealing heads 14, two moving rods 15, two extension rods 16, two springs 17, and four sealing rings 18.

[0027] Two operating slots 13 are respectively opened on the side walls of the two feeding sleeves 9. Two sealing heads 14 are respectively movably embedded in the top of the two feeding sleeves 9. The tops of the two moving rods 15 are respectively connected to the bottoms of the two sealing heads 14. Two extension rods 16 are respectively installed on the side walls of the two moving rods 15 and respectively movably pass through the two operating slots 13. Two springs 17 are respectively installed at the bottom of the two feeding sleeves 9 and their tops are respectively connected to the bottoms of the two moving rods 15. Four sealing rings 18 are respectively installed at the top of the two moving rods 15.

[0028] In this technical solution, when the actuating rod 12 contacts the extension rod 16 on one side of the moving rod 15, the extension rod 16 moves downward in the operating groove 13, driving the moving rod 15 downward in the feeding sleeve 9. Simultaneously, the spring 17 is compressed, and the two sealing heads 14 separate from the top of the feeding sleeve 9. When all four sealing rings 18 at the upper end of the moving rod 15 are below the exhaust holes of the gas distribution pipe 11, the high-pressure gas delivered through the gas distribution pipe 11 is discharged through the top of the feeding sleeve 9, unloading the product. After unloading, the air pump 10 stops working, and then the bottom mold 7 is driven to reset. During the reset process... The actuating lever 12 separates from the extension lever 16. Under the reset action of the spring 17, the moving lever 15 and the extension lever 16 are pushed back to their original positions. As the moving lever 15 moves upward, the two sealing heads 14 are embedded in the top of the feeding sleeve 9 to seal the top of the feeding sleeve 9. At the same time, the two uppermost sealing rings 18 are located above the exhaust position of the gas distribution pipe 11 and cooperate with the sealing heads 14 to double seal the gas supply direction of the feeding sleeve 9 to ensure the sealing effect. The two lower sealing rings 18 also seal the bottom of the feeding sleeve 9 to prevent gas from leaking through the operating groove 13 and ensure stable gas pressure.

[0029] In some technical solutions, reference Figure 1 The bottom end of the lever 12 is machined with a limiting groove 19. Four sealing rings 18 are located above and below the position where the air distribution pipe 11 connects with the two feeding sleeves 9, respectively. The extension rod 16 is movably embedded in the limiting groove 19 on the outside. A reinforcing crossbeam 20 is installed between the two feeding sleeves 9. The air distribution pipe 11 is a T-shaped air distribution pipe 11.
