Embodiment

[0025] A new type of polyolefin pipe basket head, its structure is as follows figure 1 As shown, it includes a first heater 1, a second mold core 2, a second heater 3, a second mold cavity 4, a first mold core 5, a screen basket 6, a third heater 7, a first mold cavity 8 and Phantom 9. The mold body 9, the first mold cavity 8 and the second mold cavity 4 are sequentially connected to form the shell of the machine head. The first mold core 5 and the second mold core 2 are sequentially connected to form an inner core. The inner core is located in the above-mentioned shell and forms a melt flow path with the shell. The melt flow path is made of surface-hardened and quenched and tempered chromium. Made of alloy steel. A second heater 3 and a third heater 7 are arranged on the outer surface of the mold cavity. The second mold core 2 is a hollow core mold, and a first heater 1 is arranged on its inner wall. The second mold core 2 is connected with the first mold core 5 and the mo...

Abstract

The invention relates to a novel polyolefin pipe-based basket type machine head. The machine head comprises a die cavity, a die body, a die core and heaters, wherein the die cavity and the die body are connected in sequence to form a housing; the die core is arranged into the housing to form an inner core; a melt cavity is formed between the inner core and the housing; and the heaters are arranged on the outer surface of the housing and an inside arm of the inner core. Compared with the prior art, the novel polyolefin pipe-based basket type machine head has the advantages of being wide in range of application, long in service life, simple and accurate in operation, high and stable in output and accurate in melting temperature control, and also can save the energy and reduce the consumption.

Description

technical field [0001] The invention relates to a polyolefin pipe head, in particular to a polyolefin pipe basket type head. Background technique [0002] Due to the huge channel area of ​​the screen basket, the basket head has only a very low total pressure loss and little heat loss in the die head. This low pressure and heat loss brings higher output and lower Energy consumption, higher quality products. There is no domestic manufacturer capable of producing basket heads, and such equipment is basically imported. Our company is the first company in China to learn and digest foreign advanced technology and develop a series of basket-type polyolefin pipe heads. Contents of the invention [0003] The purpose of the present invention is to provide a series polyolefin tubing basket type head which is not available in China, has a wide application range and a long service life. [0004] The purpose of the present invention can be achieved through the following technical sol...
