Description

Technical Field

[0001] The utility model relates to vulcanizing equipment, in particular to a vulcanizing machine used for insulator production. Background Art

[0002] Insulators are widely used in power systems. Their main function is to provide electrical insulation between conductors at different potentials or between conductors and grounded components, and to withstand voltage and mechanical stress. According to the insulating materials used, they can be divided into porcelain insulators, glass insulators, and composite insulators. The materials of composite insulators usually include silicone rubber, glass fiber cloth, metal joints, etc. Because they contain silicone rubber, rubber vulcanizing equipment is required in the production and preparation process. Among them, the flat vulcanizer is an important molding equipment widely used in rubber, plastic and other industries.

[0003] The working principle of the flat vulcanizer mainly involves components such as the motor, oil pump, control valve, and oil cylinder. When the motor is running, the oil enters the oil pump from the oil tank and enters the oil cylinder through the control valve, driving the plunger and the lower template platform to rise. When the pressure reaches the set upper limit, the electric contact pressure gauge will control the oil pump motor to stop running so that the pressure in the oil cylinder is maintained. Under the intelligent constant temperature of the electric heating plate, pressure is applied to the plastic or rubber raw material in the mold to form it. In the existing flat vulcanizer production process, it is necessary to manually load and unload the insulator of the mold on it. In order to improve production efficiency and reduce safety risks, it is necessary to automate the loading and unloading of the mold. Summary of the invention

[0006] The clamping assembly includes two clamping pieces fixed on the telescopic frame and distributed at intervals, two flipping pieces and a rotating driver for driving the two flipping pieces to rotate, the bottoms of the two clamping pieces are provided with a slot with an opening facing downward, the ends of the flipping pieces are provided with a hook body, and the rotating driver can drive the two flipping pieces to rotate toward the two slots, and make the hook body cover the opening of the slot in the horizontal direction; the insulator is mainly composed of two major parts: an insulating member and a connecting hardware, wherein the connecting hardware is rod-shaped and distributed at both ends, the width of the two clamping pieces matches the connecting hardware at both ends of the insulator, and the connecting hardware can be inserted into the slot, so when the flipping piece is flipped to the point where the hook body covers the opening of the slot, the insulator will be captured by the clamping assembly, and conversely, when the flipping piece is flipped in the opposite direction to the point where the hook body avoids the opening of the slot, the insulator will fall from the slot.
