Forming mold for insulating housing of fuse

Abstract

The invention discloses a forming mold for an insulating housing of a fuse and belongs to the technical field of forming molds. The forming mold comprises an operating table, an upper mold, heat absorption devices, a heat storage chamber, a lower mold, a hand generator and an automatic lifting platform; the heat storage chamber is located in the middle of the upper mold; the heat absorption devices are correspondingly arranged at the two sides of the heat storage chamber; the lower mold is located below the upper mold; an ejector rod is arranged at the middle of the bottom of the lower mold; the hand generator is located at the left side of the ejector rod; a lithium battery is arranged at the bottom left of the hand generator; the operating table is located under the lower mold; wheels are correspondingly arranged at the two sides of the operating table; and the automatic lifting platform is located under the operating table. The forming mold disclosed by the invention is scientific,reasonable and safe and convenient to use, saves energy and protects environment by maintaining the temperature of material liquid inside a heat nozzle by utilizing the heat energy emitted by coolingforming of the mold, and prevents generation of weld marks. The mechanical energy of the movement of the ejector rod is transformed into electric energy for the lifting of the automatic lifting platform, thereby saving energy. The automatic lifting platform implements lifting, which is convenient for storing and using the wheels, convenient for moving the forming mold, and saving time and efforts.

Description

technical field [0001] The invention relates to the technical field of molding dies, in particular to a molding die for an insulating housing of a fuse. Background technique [0002] A fuse is an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circuit and overcurrent protectors, fuses are one of the most commonly used protection devices. Based on this characteristic of use, the fuse case must use an insulating case. The insulating shell is a shell made of non-conductive material under the allowable voltage, but it is not an absolutely non-conductive material. Under the action of a certain applied electric field strength, processes such as conduction, polarization, loss, and breakdown will also occur. , Long-term use will also cause aging, a...

Problems solved by technology

Secondly, the existing molds for forming insulating housings of fuses are heavy and inconvenient for people to carry

Even if the wheels are set at the bottom of the forming mold, the wheels cannot bear the weight of the forming mold for a long time
