Description

Technical Field

[0001] This utility model relates to the field of mold equipment technology, specifically a high-precision high-voltage circuit breaker housing casting inner cavity mold. Background Technology

[0002] High-voltage circuit breakers (or high-voltage switches) not only interrupt or close the no-load current and load current in high-voltage circuits, but also, through the action of relay protection devices, interrupt overload current and short-circuit current when a system fault occurs. They possess a highly sophisticated arc-extinguishing structure and sufficient breaking capacity, and can be classified as: oil circuit breakers (multi-oil circuit breakers, low-oil circuit breakers), sulfur hexafluoride circuit breakers (SF6 circuit breakers), compressed air circuit breakers, vacuum circuit breakers, etc. The casing of a high-voltage circuit breaker requires casting using molds. However, most current molds have limitations, resulting in low yields of high-voltage circuit breaker blanks, and the inability to disassemble the molds causes problems during the casting process. Therefore, this paper proposes a high-precision casting mold for the inner cavity of a high-voltage circuit breaker casing.

[0003] The existing technology has the following problems:

[0004] 1. The existing high-voltage circuit breaker casing casting inner cavity mold cannot be disassembled, which causes problems for casting;

[0005] 2. Existing high-voltage circuit breaker casing casting inner cavity molds are prone to sticking to the inner wall during casting, which damages the mold's lifespan and accuracy. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-precision high-voltage circuit breaker housing casting inner cavity mold, which solves the problems of non-disassembly causing trouble for casting and easy sticking to the inner wall during casting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision high-voltage circuit breaker housing casting inner cavity mold, including a cooling box, a cooling groove provided inside the cooling box, a fan provided at the top of the inner side of the cooling box, a first mold provided in the middle of the inner side of the cooling box, a second mold provided on the other side of the first mold, a top mold provided on the top of the first mold, a left mold provided on one side of the first mold, a right mold provided on the other side of the second mold, a locking block provided inside the first mold, a locking groove provided inside the second mold, and an anti-sticking layer provided on the inner surface of the second mold.

[0008] As a preferred technical solution of this utility model, the cooling tank is provided in two sets arranged on both sides of the first mold and the second mold.

[0009] As a preferred technical solution of this utility model, the mold is a split structure and is divided into a first mold and a second mold. The first mold and the second mold are sized to match and are connected by a movable connection.

[0010] As a preferred embodiment of this utility model, the anti-adhesive layer is provided in two sets and is bonded to the first mold and the second mold respectively, and the anti-adhesive layer is made of aluminum alloy.

[0011] As a preferred embodiment of this utility model, the card block and the card slot are sized to match and have an insertion connection.

[0012] As a preferred technical solution of this utility model, the top mold, the left mold, and the right mold are all divided into two parts by a symmetrical line without error.

[0013] As a preferred embodiment of this utility model, the fan is provided in two sets and is respectively arranged on both sides of the first mold and the second mold.

[0014] Compared with the prior art, this utility model provides a high-precision casting inner cavity mold for high-voltage circuit breaker housings, which has the following beneficial effects:

[0015] 1. This high-precision high-voltage circuit breaker housing casting inner cavity mold is designed with a separable structure and the first mold and the second mold are size-matched. The first mold and the second mold are then assembled, and a locking block is inserted into the slot. Then the first mold is inserted and connected to the second mold. Conversely, the first mold can be pulled out for disassembly. This makes mold disassembly convenient and brings convenience to casting.

[0016] 2. This high-precision high-voltage circuit breaker housing casting inner cavity mold is equipped with a cooling box. The mold is placed inside the cooling box, and then the material is poured into the mold. An anti-stick layer is then provided to prevent material from sticking to the inside of the mold. Coolant is then poured into the cooling tank inside the cooling box to lower the temperature of the outside of the mold. Finally, a fan is turned on to conduct the heat inside the cooling box away. This achieves the effect of preventing material from sticking to the inner wall of the mold during casting, extending the service life and improving the accuracy of the mold.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 In this embodiment: a high-precision high-voltage circuit breaker housing casting inner cavity mold includes a cooling box 1 for setting other cooling components, a cooling tank 2 inside the cooling box 1 for storing coolant, a fan 3 at the top inside the cooling box 1 for heat conduction, a first mold 4 in the middle inside the cooling box 1 for connecting a second mold 5, a second mold 5 on the other side of the first mold 4 for connecting the first mold 4, a top mold 6 on the top of the first mold 4 for material casting into the mold, a left mold 7 on one side of the first mold 4 for casting the circuit breaker housing, a right mold 8 on the other side of the second mold 5 for casting the circuit breaker housing, a locking block 11 inside the first mold 4 for connecting a locking groove 10, a locking groove 10 inside the second mold 5 for inserting the locking block 11, and an anti-stick layer 9 on the inner surface of the second mold 5 to prevent sticking to the inner wall of the mold during casting.

[0024] In this embodiment, the cooling tank 2 is provided in two sets arranged on both sides of the first mold 4 and the second mold 5, so that the coolant enters the cooling tank 2 to cool the area around the mold; the mold is a separable structure and is divided into the first mold 4 and the second mold 5. The first mold 4 and the second mold 5 are sized to match and have a movable connection, making the mold structure simpler; the anti-stick layer 9 is provided in two sets and is bonded to the first mold 4 and the second mold 5 respectively. The anti-stick layer 9 is made of aluminum alloy, so that the material is not easy to stick to the inner wall; the card block 11 and the card slot 10 are sized to match and have an insertion connection, making the installation and disassembly of the first mold 4 and the second mold 5 simpler; the top mold 6, the left mold 7 and the right mold 8 are all divided into two parts symmetrically with no error, making the mold more accurate; the fan 3 is provided in two sets and is arranged on both sides of the first mold 4 and the second mold 5 respectively, so as to improve the cooling effect and prevent the material from sticking to the inner wall.

[0025] The working principle and usage process of this utility model are as follows: The operator installs the first mold 4 and the second mold 5, inserts the card block 11 into the card slot 10, and then places the mold into the cooling box 1, injects coolant into the cooling tank 2, turns on the fan 3, and then places the material into the top mold 6 for casting. After being cooled by the cooling system, the mold temperature is kept within a low range, so that the material does not stick to the inner wall of the mold, and the mold precision is better. This can meet the working requirements of a high-precision high-voltage circuit breaker housing casting inner cavity mold.
