Problems solved by technology

[0017] In the same way, in the second method, the thermal efficiency deteriorates, since each treatment tube heats and cools the mold, which involves high energy costs, as in the previous case, again due to the cooling taking place by contact, which determines the low efficiency
In this method, the tube is introduced cold, the mold acts as a heater and as the mold itself, it has many orifices to allow the discharge of the fluid previously used to heat the tube, making the execution of the mold more expensive

Embodiment Construction

[0043] As mentioned in figure 1 It can be seen that the device of the present invention includes a complete mold formed by a first head 1, a second head 17, and a central body 14. The central body 14 communicates with the head 1 through their ends, 17 associate (associate). In these heads 1, 17, there are provided a fixing device 3 that fixes the position of the blank tube 10, and an orifice 8 made there, which makes the inside of the mold 1, 17, 14 and External communication to apply pressure or vacuum equally. The first head 1 has a reduced-sized sealing bushing 2 coupled to one end of the blank tube 10 in the axial direction, and the second head 17 has a support bushing 16 .

[0044] figure 1 It is also shown that the device incorporates (including, incorporate) a rigid perforated guide 5 which is located axially in the center of the inside of the mold 1, 17, 14 and is provided with an opening 9. The guide device 5 is fixed to the support bushing 16 by one of its ends, and ...

Abstract

The present invention provides equipment and methods for producing molecularly bidirectional plastic pipes. The device consists of a mold (1, 17, 14) consisting of a central body (14) and a first head (1) connected on the opposite side of the central body (14) and a second head (17), and it has a rigid and perforated guide (5) axially centered inside the mold (1, 17, 14), on which the longitudinal A blank tube (10) is coupled. The guide is provided with orifices (9) for passing therethrough an expansion fluid (18) without any heat exchange between the blank tube (10) and the mold (1, 17, 14) The expansion of the blank tube (10) against the inner wall of the mold (1, 17, 14) is caused.

Description

Technical field [0001] The field of application of the present invention includes in the manufacturing process of tubular profiles or molecularly oriented plastic pipes and especially discontinuous or "in-batch" systems. [0002] The present invention relates to equipment and methods for preparing molecularly oriented plastic tubes, especially for their applications in the preparation of tubes, signal elements and optical structure elements. [0003] The object of the present invention consists of forming a plastic tube with molecular orientation even by gas as a whole in a rapid and energy-efficient, simple-to-execute method, which makes it possible to reduce the cost and time in the production of plastic tubes, as well as the cost of necessary equipment , So that the final product using the equipment and manufacturing method of the present invention can reach the market at a more competitive price. [0004] The equipment is based on a specially designed mold that incorporates a ser...
