Example Embodiment

[0012] In Figure 1, the sizing tube (3) has two cooling slots (9) parallel to its axis. Both ends of the cooling slot (9) are blocked by plugs (5). The sizing tube (3) There are cooling water rings (7) on both sides of the cooling water ring (7), a cooling water jacket (4) is provided on the outside of the cooling water ring (7), and a vacuum jacket (2) and a sizing tube (3) are provided on the outside of the cooling water jacket (4). There are 5 rows of vacuum holes (10) between the two cooling water rings. There is a cooling water outlet (6) on the left cooling water jacket (4), and a cooling water inlet (1) on the right cooling water jacket (4). The sleeve (2) is provided with a vacuum suction port (8).

[0013] The cooling water enters the right cooling water ring (7) from the cooling water inlet (1), reaches the left cooling water ring (7) through the cooling slot (9), and flows out through the cooling water outlet (6) to calibrate The tube is cooled. A closed space is formed...

Abstract

An expanding die for the thermally contracted pipe is composed of a sizing pipe with a longitudinal cooling hole through which the cooling water flows, a cooling water jacket, and a vacuum jacket. It has high expanding speed (10 m/min) and cooling effect.

Description

【Technical field】 [0001] The invention relates to the manufacture of heat-shrinkable tubes, in particular to the field of expansion molds for heat-shrinkable tubes. 【technical background】 [0002] In the heat shrinkable tube expansion mold of the prior art, there is no cooling water in the place with the vacuum hole, and there is no vacuum hole in the place with the cooling water, the mold structure is complicated, and the manufacturing cost is expensive. The effect is not good, and the expansion speed is limited. Generally, the expansion speed will not exceed 5 m / min. 【Content of invention】 [0003] The object of the present invention is to provide a heat shrinkable tube expansion mold, the cooling effect of the mold is very good, the expansion speed of the mold can reach more than 10 m / min, and the expansion is stable. [0004] The technical solution adopted by the present invention to solve the technical problem is: a heat shrinkable tube expansion mold, including a si...
