Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a casting mould for an outer plate of a circuit breaker. Background Art

[0002] The outer plate of the circuit breaker needs to be produced using a metal casting mold. When the mother mold and the sub-mold of the mold are combined, the molten raw material is injected into the area between the mother mold and the sub-mold. After cooling, the outer plate in the mother mold and the sub-mold is formed, and the formed outer plate can be removed at this time.

[0003] However, after the outer panel is formed in the mother mold and the daughter mold, when the mother mold and the daughter mold are separated, the outer panel will still fit tightly to the mother mold. At this time, the staff needs to use tools to remove the outer panel from the mother mold, which is inconvenient and increases the burden on the staff.

[0004] Therefore, the traditional metal casting mold can be improved so that it can avoid the above-mentioned problems. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a circuit breaker outer plate casting mold.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A circuit breaker outer plate casting mold comprises a mother mold and a sub-mold, wherein the mother mold is provided with a groove, a push block is slidably connected to the groove, a fixing rod is fixed to the push block, the fixing rod is slidably connected to the mother mold, an end block is fixed to the end of the fixing rod, a spring is sleeved on the fixing rod, and an adjusting member for adjusting the position of the push block is provided on the mother mold.

[0008] Preferably, the adjusting member comprises a fixing block fixedly connected to the bottom of the female mold, and an electric push rod is mounted on the fixing block, a knocking plate is fixed to the end of the electric push rod, and the knocking plate abuts against the end block.

[0009] Preferably, when the push block is engaged with the groove, the end block does not contact the knocking plate.

[0010] Preferably, a connecting block is fixed at the bottom of the mother mold, and a through hole is provided on the connecting block which is slidably connected to the fixed rod, and round hole one and round hole two are provided on the connecting block, and round rod one and round rod two are fixed on the knocking plate, and round rod one is slidably connected to round hole one, and round rod two is slidably connected to round hole two.

[0011] Preferably, an elastic rubber gasket is provided on the portion of the knocking plate that contacts the end block.

[0012] Preferably, when the push block is engaged with the groove, a sealing ring is provided on the portion where the outer side wall of the push block contacts the groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the present application, the knocking plate moves under the action of the electric push rod to knock the end block. During the movement of the end block, the push block moves together. The push block can push the outer plate in the mother mold to separate the outer plate from the mother mold, making it easier for the staff to remove the outer plate from the mother mold. It is more convenient and quicker, and the staff does not need to use tools to separate the outer plate from the mother mold.

[0015] 2. In the present application, round rod one and round rod two are respectively slidably connected to round hole one and round hole two, so that the knocking plate will not be offset during movement, and the end block is blocked by the connecting block during movement, so the end block will not contact the bottom of the mother mold, thereby protecting the mother mold.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] The utility model provides a technical solution, please refer to Figure 1-5 :

[0026] A circuit breaker outer plate casting mold includes a mother mold 1 and a sub-mold 2. The mother mold 1 is provided with a groove 4, a push block 5 is slidably connected to the groove 4, and a fixing rod 6 is fixed to the push block 5. The fixing rod 6 is slidably connected to the mother mold 1, an end block 7 is fixed to the end of the fixing rod 6, and a spring 8 is sleeved on the fixing rod 6. The mother mold 1 is provided with an adjusting member for adjusting the position of the push block 5. When the push block 5 is engaged with the groove 4, a sealing ring is provided on the part of the outer wall of the push block 5 that contacts the groove 4, which can effectively prevent the melted raw material from entering the groove 4.

[0027] Embodiment 2:

[0028] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the adjusting member includes a fixed block 3 fixedly connected to the bottom of the mother mold 1, and an electric push rod 13 is installed on the fixed block 3, a knocking plate 10 is fixed to the end of the electric push rod 13, and the knocking plate 10 is in contact with the end block 7, and an elastic rubber gasket is provided on the part where the knocking plate 10 contacts the end block 7. When the push block 5 is engaged with the groove 4, the end block 7 at this time does not contact the knocking plate 10. Therefore, during the extension and retraction process of the electric push rod 13, the knocking plate 10 knocks the end block 7, so that the push block 5 pushes the outer plate of the circuit breaker in the mother mold 1 during movement, causing the outer plate to separate from the mother mold 1, thereby facilitating the staff to take away the outer plate at the mother mold 1.

[0029] Embodiment three:

[0030] The technical solution is basically the same as that of the first embodiment, except that Figure 3As shown, a connecting block 9 is fixed to the bottom of the mother mold 1, and a through hole 16 is provided on the connecting block 9 for sliding connection with the fixed rod 6, a round hole 14 and a round hole 2 15 are provided on the connecting block 9, and a round rod 11 and a round rod 2 12 are fixed on the knocking plate 10, and the round rod 11 is slidably connected to the round hole 14, and the round rod 2 12 is slidably connected to the round hole 2 15. The knocking plate 10 knocks the end block 7 under the action of the electric push rod 13, and the push block 5 moves together with the end block 7 during the movement. At this time, the round rod 11 and the round rod 2 12 are respectively slidably connected to the round hole 14 and the round hole 2 15, so that the knocking plate 10 will not be offset during the movement, and the end block 7 is blocked by the connecting block 9 during the movement, so the end block 7 will not contact the bottom of the mother mold 1, thereby protecting the mother mold 1.

[0031] In summary, after the outer plates in the mother mold 1 and the sub-mold 2 provided in this embodiment are formed, the sub-mold 2 is separated from the mother mold 1. Then the electric push rod 13 extends, causing the knocking plate 10 to move to the knocking end block 7, so that the end block 7 moves upward, and the push block 5 moves upward together with the end block 7, and the push block 5 pushes the outer plate in the mother mold 1. Until the outer plate in the mother mold 1 is separated from the mother mold 1, the outer plate can be taken away at this time. Then the electric push rod 13 contracts, and under the elastic force of the spring 8, the end block 7 is pushed downward, and the push block 5 returns to the groove 4.

[0032] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
