Problems solved by technology

[0002] Square insulating tubes are widely used in transformer insulation products. The existing molds for manufacturing square tubes have complex structures, cumbersome processing techniques, long production cycles, usually about a week, and high costs. The molds produced are not only too heavy, but also inconvenient to operate.

Abstract

The invention discloses a PVC square pipe die. The PVC square pipe die comprises a die body, a rear support plate, a front support plate, a confluence plate, a mouth die, an internally-arranged main core bar and an internally-arranged flow division cone which are sequentially connected. The flow division cone is embedded in the rear support plate, the front end of the flow division cone is in a trapezoid shape, and the rear end of the flow division cone is closely attached to one end of the main core bar. The other end of the main core bar extends to the outlet end of the mouth die. The main core bar is embedded in the front support plate and penetrates the confluence plate and the mouth die. Compared with a former square pipe die, a cold die and a water hole structure are omitted, cooling is not needed, the production process is simplified, and machining is convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical moulds, in particular to a PVC square pipe mould. 【Background technique】 [0002] Square insulating tubes are widely used in transformer insulation products. The existing molds for manufacturing square tubes have complex structures, cumbersome processing techniques, long production cycles, usually about a week, and high costs. The molds produced are not only too heavy, but also inconvenient to operate. 【Content of invention】 [0003] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a PVC square pipe mold, which has a simple structural design and is easy to manufacture. The square pipe is made of PVC material without cooling, which simplifies the manufacturing process and has strong practicability. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A PVC square tube mould, compris...
