Embodiment Construction

[0017] Embodiment 1 of a mold gate for pouring an insulating cylinder of the present invention, as figure 1 As shown, the mold gate includes a gate body, the upper part of the gate body has a storage hopper 1, and the outer wall of the storage hopper 1 is provided with a cooling box 4. In this embodiment, the cooling box is a cooling water tank, and the cooling box is filled with Cooling water, two cooling boxes 4 are arranged at circumferential intervals around the storage hopper 1, which can increase the cooling area of ​​the cooling box and improve the cooling effect; the two cooling boxes are arranged symmetrically, so that other parts of the casting mold can be avoided, and the cooling water can be avoided. There is interference with the casting mold.

[0018] The lower part of the gate body has a spout connected with the storage hopper. In this embodiment, the lower end of the storage hopper 1 is connected with a conduit 2, which forms the spout. The conduit 2 and the st...

Abstract

The invention relates to a mold gate for pouring an insulating cylinder. The mold gate comprises a gate body, wherein a storage hopper is arranged at the lower part of the gate body, and a pouring nozzle communicated with the storage hopper is arranged at the lower part. When the mold gate is used, the storage hopper can store enough materials; in the curing process of the insulating cylinder, the storage hopper can continuously replenish the materials into a molding cavity of a mold, and a curing furnace is not needed to open to add the materials in the pouring nozzle; and meanwhile, when the insulating cylinder is cured to shrink, the materials in the storage hopper can be timely supplied into the molding cavity of the mold to prevent the condition of waste products due to generation of sucking holes in the insulating cylinder, so that te production cost is saved, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a mold gate for pouring insulating cylindrical workpieces, belonging to the technical field of molds. Background technique [0002] In electrical equipment, the insulating cylinder is mostly formed by integral casting of epoxy resin. During casting, the epoxy resin is injected into the mold through the gate of the mold. After the epoxy resin is poured, it needs to be placed in a curing furnace for curing. The resin will continue to shrink, which will easily lead to the "pumping hole" phenomenon of the insulating cylinder and become a waste product. Therefore, during the curing process of the epoxy resin, it is necessary to continuously replenish epoxy resin into the mold gate to avoid the "pumping hole" of the insulating cylinder. hole" phenomenon. Due to the large degree of shrinkage of the epoxy resin, the entire curing process needs to be refilled several times, and the door of the curing furnace needs to be opened for each...
