SU919876A1 - Mould for making articles with ducts for electric wiring - Google Patents

Description

The invention relates to devices for the manufacture of a building structure, in particular, to the manufacture of products for large-panel house construction.

The well-known form for the manufacture of products with channels for electrical wiring, contains a pallet and a composite duct former tl.

The disadvantage of this form {is the difficulty of manufacturing kangsifiers and extracting them from a 6-shaped product.

 The most familiar of the known technical solutions to the present invention is the form for the manufacture of products with channels for electrical wiring, comprising a pallet and beams installed on it with openings through which elastic tubular ducting 2 is passed., /

The disadvantage of this device is the difficulty of extracting the channel. the former is made of a molded product due to the equality of the diameters of the hardener and the molded channel, which complicates the operation of the mold ..

The purpose of the invention is to improve the usability and simplify constructions. instructions. .

This goal is achieved in that the form for the manufacture of products with channels for electrical wiring, containing the pallet and installed on it. boards with holes through which elastic tubular channels 10 are passed, are provided with a needle for supplying compressed air, and; board side- filled with conical sleeves placed in the holes and elastic conical stoppers between which the ends of the channel formers are fastened.

FIG. -1 and: the form is depicted, top view; in fig. 2 - an elastic tubular duct attachment unit ...

 : channel formers 4G Dl feed; In addition to the air in the duct forming 4, the shape is equipped with a needle 5. The beads 2 are made with 3 conical sleeves 6 placed in the holes and elastic cone plugs 7 between which the ends of the duct forming 4 are fixed. -Concluded. in the next;, after installation - And. fixing the boards 2 on the pallet 1. well-known sponsor lay-in the design position duct 4, skip their ends through the conical sleeve b, then l insert from the ends: channel 4 conical plugs 7 and slide them together with the ends of the inverter canals 4 into the conical sleeves b, thus jamming the ends of the ducting tools between the sleeve b and the stopper 7. Next, proc. channel formers 4 aerated air. Filled with compressed air up to. 0.1–0.5 atm tubular ductworkers acquire rigidity and stability during the molding of products. At the end of the heat treatment of the molded product, the still-cooled plugs 7 (made, for example, from a polyethylene material) are easily removed from the tapered bushing 6. It is also easily removed from the product after the Compressed air exits and the channel generators 4.. The proposed form is easy to use, as it provides easy extraction of channel formers from a molded product without its being made. In addition, it is structurally simple. The invention The form for the manufacture of products with channels for electrical wiring, comprising a pallet and beads G installed thereon, with holes through which elastic tubular ducting channels pass, characterized by the fact a needle for supplying compressed air, and the beads are made with conical sleeves and elastic conical plugs placed in the holes, between which the ends of the ducting rods are fixed.
