[0012] As a preference, a spring is provided between the piston and the inner wall surface of the piston cylinder.

[0013] The beneficial effects of the present utility model:

[0014] 1. By fitting the upper mold and the lower mold together, with a cover plate a provided on the end face of the upper mold and a cover plate b provided on the end face of the lower mold, a number of fixing rods are provided on the cover plate b, and the cover plate b is sleeved on the fixing rods and fixed by bolts.

After the baffles are fully opened, the finished product in the molding cavity falls under the drive of the gas injection through the air pipe, avoiding burns during manual material taking and improving safety.

[0016] In summary, the device has the advantages of being easy to disassemble, good stability, avoiding manual feeding, improving safety, and high molding efficiency, and is particularly suitable for the technical field of molding dies. Brief Description of the Drawings

[0026] Embodiment 1

[0027] As Figures 1 to 6 shown, a rapid prototyping mold for a motor bracket with good stability includes an upper mold 1 and a lower mold 2 that fits with the upper mold. A forming cavity 3 is provided in the upper mold 1. A group of baffles 4 that move in opposite directions are slidably provided on the end face of the lower mold 2. A piston cylinder 5 is provided below the baffle 4. A piston 6 is slidably provided in the piston cylinder 5. An air pipe 7 is provided between the piston cylinder 5 and the upper part of the forming cavity 3. The baffle 4 is used to drive the piston 6 to move during the movement process. While the piston 6 moves, air is gradually injected into the forming cavity 3 through the air pipe 7 to blow out the finished product in the forming cavity 3.

[0028] As Figure 3 shown, a chute 21 is opened on the end face of the lower mold 2. A threaded rod 22 is rotatably provided in the chute 21. A slider 23 is provided on the side of the baffle 4. The slider 23 is slidably provided on the threaded rod 22.

[0029] It is worth mentioning here that by opening a chute 21 on the end face of the lower mold 2 and slidably arranging the baffle 4 in the chute 21 through the slider 23, the stability of the baffle 4 during sliding can be ensured.

[0030] As shown in Figures 2 and 4, a placement groove 31 is opened on the lower mold 2 below the baffle 4. The piston cylinder 5 is placed on the placement groove 31. A piston rod 32 is provided on the side of the piston 6. A linkage rod 33 is provided between the baffle 4 and the piston rod 32.

[0031] It is worth mentioning here that by providing a linkage rod 33 between the baffle 4 and the piston rod 32, the baffle 4 can drive the piston rod 32 to move through the linkage rod 33 while moving, thereby driving the piston 6 to move for piston movement.

[0032] As Figure 2 shown, a blanking channel 41 is provided on the lower mold 2 directly below the forming cavity 3.

[0033] As Figure 1 shown, cover plates a 51 and cover plates b 52 are respectively provided on the end faces of the upper mold 1 and the lower mold 2. A plurality of fixing rods 53 are provided on the cover plates b 52. The cover plates b 52 are sleeved on the fixing rods 53 and fixed by bolts 54.

[0034] It is worth mentioning here that by sleeving the cover plate b52 on the fixed rod 53 and fixing it with bolts 54, fixing with bolts 54 can make the upper and lower molds fit firmly. There is no need to open and then close the mold after forming, which avoids deviation during mold closing, and the bolts are convenient for disassembly and assembly for inspection and maintenance.

[0035] As Figure 5 shown, a threaded section a61 and a threaded section b62 are provided on the threaded rod 22, and the thread directions of the threaded section a61 and the threaded section b62 are opposite. A set of the baffles 4 are respectively arranged on the threaded section a61 and the threaded section b62.

[0036] It is worth mentioning here that by arranging the baffles 4 on the threaded section a61 and the threaded section b62, the threaded rod 22 with opposite thread directions can drive the baffles 4 to move in opposite directions, so as to open the baffles 4 to facilitate the dropping of the finished product.

[0037] As Figure 2 shown, a spring 71 is arranged between the piston 6 and the inner wall surface of the piston cylinder 5.

[0038] It is worth mentioning here that by arranging a spring 71 between the piston 6 and the inner wall surface of the piston cylinder 5, the spring 71 can drive the piston 6 to reset after the baffle 4 is reset.

[0039] The working process is as follows:

[0040] After the forming is completed, the drive system drives the threaded rod 22 to rotate. The threaded rod 22 drives the baffles 4 on both sides to move in opposite directions through the threaded sections with opposite thread directions. While the baffles 4 are moving, the piston rod 32 is driven to move through the linkage rod 33. The piston rod 32 drives the piston 6 to move. The piston 6 moves to perform a piston motion to inject gas into the forming cavity 3 through the air pipe 7. After the baffles 4 are fully opened, the finished product in the forming cavity 3 drops from the blanking channel 41 under the action of the injected gas. Then the threaded rod 22 rotates in the reverse direction to drive the baffles 4 to reset, and the piston 6 is driven by the spring 71 to reset to prepare for the next round of forming.
