Problems solved by technology

[0003] The supporting cylinder in the high-voltage switch, as the main supporting member of the high-voltage switch, is usually processed by casting. The traditional casting method generally adopts low-pressure casting technology. Due to many reasons such as pressure and exhaust, shrinkage and shrinkage are prone to occur. Holes, thus affecting the casting effect of the support cylinder, it is easy to cause the casting to be unusable

Embodiment 1

[0026] A high-voltage switch aluminum-magnesium alloy support cylinder sand core mold, including a mold body, a first mold 2, a material injection port 5, a sand core 6, a limit groove 8, a second shaft 9, a second mold 13 and a knob 14, the mold The body is composed of a first mold 2 and a second mold 13. The mold body is provided with a sand core 6. The first mold 2 and the second mold 13 are both provided with a casting groove 4. The first mold 2 and the second mold 13 have both ends. A first rotating shaft 1 and a second rotating shaft 9 are respectively provided, a limiting groove 8 is provided inside the second rotating shaft 9, an exhaust port 10 is provided at one end of the sand core 6, the inner wall diameter of the casting groove 4 is larger than the outer wall diameter of the sand core 6, and the exhaust port 10 penetrates through the inside of the second rotating shaft 9, and the outer wall of the exhaust port 10 is provided with a limit ring 11 which is fitted wit...

Embodiment 2

[0030] The assembly process of the mold body is as follows:

[0031] S1: Separate the first mold 2 from the second mold 13, place the sand core 6 inside the casting groove 4, and fit the limit ring 11 on the surface of the exhaust port 10 with the limit groove 8 inside the second shaft 9 combine;

[0032] S2: The staff matches the first mold 2 and the second mold 13 with each other, connects the connecting blocks 3 through the bolt through the screw hole 7, and stably combines the first mold 2 and the second mold 13 to form a mold body;

[0033] S3: The molten aluminum-magnesium alloy is injected into the mold body through the injection port 5, the sealing block 12 is inserted into the injection port 5, and the knob 14 is stably connected to the screw port 15 to seal and keep the injection port 5.

[0034] Working principle: The sand core 6 is placed inside the mold body. The sand core 6 is designed in a hollow form, and an exhaust port 10 is provided at one end of the sand c...

Abstract

The invention discloses a high-voltage switch aluminum magnesium alloy supporting cylinder sand core mold and an assembling method thereof.The high-voltage switch aluminum magnesium alloy supporting cylinder sand core mold comprises a mold body, a first mold body, a material injection opening, a sand core, a limiting groove, a second rotating shaft, a second mold body and a rotary knob, the mold body is composed of the first mold body and the second mold body, and the sand core is arranged in the mold body; casting grooves are formed in the first mold and the second mold correspondingly, a first rotating shaft and a second rotating shaft are arranged at the two ends of the first mold and the two ends of the second mold correspondingly, an exhaust port is formed in one end of the sand core, material injection openings are formed in one side of the first mold and one side of the second mold correspondingly, and rotary knobs are arranged at the upper ends in the material injection openings. A spring is arranged at the lower end of the knob, and the lower end of the spring is connected with a sealing block. The mode that the mold body is combined with the sand core is adopted, the effect of guaranteeing normal discharge of air in the sand core in the casting process is achieved, the problem of shrinkage cavities can be effectively prevented, and the heat preservation effect on the injection port is better.

Description

technical field [0001] The invention relates to the technical field of casting molds, in particular to a high-voltage switch aluminum-magnesium alloy supporting cylinder sand core mold and an assembling method thereof. Background technique [0002] High-voltage switch, also known as high-voltage circuit breaker, is a kind of power equipment commonly used in power systems. It can not only cut off or close the no-load current and load current in high-voltage circuits, but also cut off the relay protection device when the system fails. Overload current and short-circuit current, it has quite perfect arc extinguishing structure and enough current breaking capacity. [0003] The support cylinder in the high-pressure switch, as the main support member of the high-pressure switch, is usually processed by casting. The traditional casting method generally adopts the low-pressure casting process. Due to pressure and exhaust and many other reasons, it is easy to produce shrinkage and s...
