Detailed Description

In fig. 1, the utility model consists of three parts, 1 central spider 1, 4 square cores 2 and 4 outer moulds 3.

Referring to fig. 2, a central cross-shaped bracket 1 and 4 external dies 3 are combined together to form 4 cavities, 4 square internal cores 2 are respectively placed in the 4 cavities, so that 4 square annular cavities are formed, and the size of the 4 square annular cavities is consistent with the structural size of the composite square pipe, namely, the die cavity for manufacturing the composite square pipe.

Referring to fig. 3, both ends of the central cross-shaped bracket 1 are provided with handles for clamping on the tape winding device. The handle is provided with a hanging clamping groove which is matched with the hanging clamping groove in the curing oven, so that the mold is conveniently hung in the curing oven.

Referring to fig. 1, one end of the square inner core 2 is provided with a demoulding clamping groove which is adapted to demoulding equipment, so that the square inner core and the composite square tube can be conveniently separated to complete demoulding.

Referring to fig. 4, the outer side structure of the outer die 3 is 1/4 circular arcs, the inner side structure is two surfaces perpendicular to each other, and 4 outer dies 3 are matched with the central cross-shaped bracket 1 to form an outer cylindrical structure, so that a heat shrinkage belt can be wound outside the die conveniently by using a belt winding machine.

This embodiment is used as follows: the raw materials for manufacturing the composite square pipe blank 4 are firstly laid outside the square inner core 2 to form the composite square pipe blank 4. Then 4 square inner cores 2 with composite square pipe blanks 4 are placed at 4 corners of the central cross-shaped bracket 1, and 4 outer dies 3 are respectively placed outside the composite square pipe blanks 4, so that the outer structures of the dies form a cylinder. And then winding the thermal contraction belt outside the mould by using a belt winding machine, and finally hanging the embodiment wound with the thermal contraction belt inside a curing furnace. And heating and curing for a period of time, and curing and forming the composite square pipe. Then the heat shrinkable tape outside the embodiment is removed, the outer die 3 is opened, and the square inner core 2 and the composite square tube are taken out. And finally, separating the composite square pipe from the square inner core 2 by using a demoulding machine to finish demoulding, thereby obtaining a composite square pipe product.
