Description
Technical Field
The utility model relates to a forming die, concretely relates to forming die of moulded case circuit breaker housing.
Background
The molded case circuit breaker is widely applied to the departments of industry and agriculture, traffic, mines, civil buildings, national defense and the like, plays a great role in the transmission and distribution of electric power and the protection of motors, and is a product with large use amount and wide use range in low-voltage electric appliances. A molded case circuit breaker is a switching device capable of closing, carrying, and opening a current under a normal circuit condition, and closing, carrying, and opening a current under an abnormal circuit condition (including a short-circuit condition) within a prescribed time. In the production process, the housing of the molded case circuit breaker is manufactured by adopting an injection molding process, the structural design of the existing molding die is unreasonable, material slag is easy to produce in a runner of the molding die, and when the die is closed again, the molding die generates a gap, so that flash and burrs are generated on a product. Therefore, the forming die of the plastic case circuit breaker housing has the defects of low production efficiency, high production cost, complex structure and unreliable performance.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a forming die of moulded case circuit breaker housing of simple structure, dependable performance, production efficiency height, low in production cost.
For realizing the above-mentioned purpose, the utility model discloses a forming die of moulded case circuit breaker housing, including base, backup plate, the activity of setting on the base set up the movable mould board on the backup plate, set up static template, the activity setting ejector pin subassembly in the base on the movable mould board, movable mould board and static template between be formed with housing model chamber, static template on be provided with the sprue gate, the sprue gate in be provided with the runner cup, the movable mould board on be provided with the cold silo of storage that is the quincunx shape, the cold silo of storage be linked together with the runner cup, housing model chamber and store and be provided with the stream material passageway between the cold silo.
The beneficial effect of above-mentioned structure is: the plastic case circuit breaker housing forming die is characterized in that a storage cold material groove is formed in the movable die plate, and cold materials are flushed into the storage cold material groove in the injection molding process, so that injection molding materials are not prone to waste, material slag is not prone to generating in the die sinking state, and the injection molding materials can be saved.
Particularly, a positioning ring matched with the injection molding machine is arranged on the static template corresponding to the material injection port. The positioning ring is arranged on the static template and is convenient to disassemble, so that the positioning ring is convenient to assemble with an injection molding machine, and the mounting efficiency of the forming die of the plastic case circuit breaker housing is improved.
