RU2505399C1 - Moulding rack system for production of articles from foaming materials - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: moulding rack system for production of articles from foaming materials poured into dies and moulds composed of several modules. Modules include the carcass with three working cells accommodating the mould. Said mould is equipped with heat and power circuits for mould thermal stabilisation, ball guides for rolling the mould to pour material on one side of the rack and discharging of article from the mould on other side of the module. Note here that mould covers are furnished with guides for vertical displacement in mould opening and closing.

EFFECT: higher quality of products, improved process mechanisation.

Description

The invention relates to devices for the production of products from expandable materials, for example, in the manufacture of heat and noise insulating finishing panels from rigid polyurethane foam, panels of fixed formwork lined with decorative tiles, foam concrete blocks, aerated concrete and other products produced in molds connected to a heat carrier for thermal stabilization.

The technical result is that with the help of this press racking system it is possible to efficiently place the molds with the connected coolant for thermostabilization of products, to have two independent service areas for molds, namely: a zone for processing molds and a zone for pouring materials into them, it became possible increase the level of mechanization of mold maintenance using a robotic arm of the "mechanical arm" type in a small production space, eliminate the process of moving molds, which is extremely negative It has an active effect on the quality of products during their unwanted shaking and vibrations.

The problem is solved due to the fact that the press-rack system for the production of products from expandable materials and materials poured into matrices and molds consists of several modules, which include: a frame with three working cells, inside of which there is a mold (mold) equipped with heat power and energy networks for the process of its thermal stabilization, devices in the form of ball guides for rolling out the mold for pouring material on one side of the press rack module and unloading the product from the mold on the other side of the module, mold covers with guides for their vertical movement when opening and closing the molds.

At the same time, the problem of more efficient use of an expensive casting machine for preparing polyurethane foam was solved by placing more molds in the reach of such filling, since the process of filling one mold with prepared components is 6-8 seconds, and the polymerization process of the filled composition is 18 minutes, so we can conclude that this installation is capable of processing up to 120 molds. The use of the developed press-rack system allows to reduce the area of the casting area, increase the number of molds processed by one casting machine to 84, which contributes to a 6-fold increase in labor productivity, and to eliminate the intersection of the staff following the mold between the pouring zones and the finished goods unloading zone .

DESCRIPTION TO FIGURES:

The figure 1 shows a section consisting of three modules 1 of a press rack system in a perspective view and shows the installation cell 2.

The figure 2 shows the end view of the module of the press-racking system having three working cells 2 and shows the principle of operation of the "working cells", namely the principle of operation of the withdrawable extension mechanism 3, the beam 4, the mold 5 and the cover of the mold 6 rest items are not shown conditionally:

a) demonstrates the moment of the “working cell” located in the production process “closed mold manufacturing products”.

b) shows the moment of the “working cell” located in the production process, the press is raised and the mold is open, the sliding mechanism 3 pushed the mold 5 into the area to fill it from the feed head 7 with the working composition.

c) demonstrates the moment of the “working cell” located in the production process, the press is raised and the mold is open, the sliding mechanism 3 pushed the mold 5 into the zone for extracting the finished product 8 and processing the mold.

Moreover, all three processes “a”, “b”, “c” proceed simultaneously and do not interfere with each other.

The figure 3 shows a working cell front view (fragment) showing the elements of one "working cell" including:

The drives of the withdrawable mechanism 9, and one drive is connected to one withdrawable mechanism of full extension 10, which ensures the installation pedestal 11 moves in one direction, and the other drive is connected respectively to another mechanism of full extension 10, which ensures the installation pedestal 11 moves in the other direction, bracket 12 for fastening the drive of the press 13 to the beam of the press 4 retainer-stop 14 for fixing the mounting pedestal 11 in the middle position and to counter the arising axial shear forces in the direction "Down" at the time of operation of the press, the protective casing 15 the drive mechanism 9 and withdrawable drawout mechanism 3, as well as mold 5 (one or more) and the mold cover 6.
