Problems solved by technology

[0031] However, the transversal containment devices of the known type described above are easily upgradable with the aim of making the V-shaped elements more practical and easier to implement, taking into account that the profile of the outer surface of the profiled elements varies greatly depending on the manufacturer

Embodiment Construction

[0043] The invention relates to the realization of a counter-molding element for receiving a welding bead of a plastic molding element formed during the melting of two molding elements.

[0044] In the preferred embodiment shown in the figures, the counter-mould element 1 has at least one body 2 adapted to receive at a seat at least one pair of profiled elements of plastic material welded together to obtain a door and window frame.

[0045] Each profiled element includes a weld surface weldable to a welded surface of another profiled element in a welded configuration in which the lateral faces of the profiled elements substantially adjoin one another and define locating surfaces.

[0046] In this case, the welding surfaces can be welded together by interposing, for example, a hot plate welding device which can be placed between the welding surfaces of the profiled elements.

[0047] Specifically, the method includes:

[0048] - a stage of obtaining the contour of at least a p...

Abstract

Process for the realization of counter-mould elements for the containment of welding bead of plastic profiled elements, in which counter-mould elements (1) have a main body (2) adapted to receive in abutment a pair of profiled elements of plastic material welded together to obtain a frame for windows / doors, each profiled element comprising a welding surface weldable to the welding surface of another profiled element in a welding configuration in which the lateral faces of profiled elements are substantially adjacent to one another and define a locator surface, wherein the process comprises: aphase of acquisition of the profile of a portion of the lateral faces; a phase of definition of the profile of a contact surface (3) of the main body (2) adapted to receive in abutment the locator surface, the profile of the contact surface (3) being substantially complementary to the profile of the locator surface; a phase of three-dimensional molding obtained by means of a three- dimensional molding device (4) to obtain the main body (2) starting from the profile of the contact surface (3) obtained in the phase of definition.

Description

[0001] related application [0002] The invention relates to a method for realizing a counter-mould element contained by a weld bead of a plastic molded element. Background technique [0003] In the prior art, profiled elements made of plastic (e.g. PVC or similar) most commonly used as door and window frames are welded together by melting their respective head surfaces in order to achieve fittings suitable for the same door, window or wall frame Framework. [0004] Specifically, melting is to heat the parts to be joined by means of a suitable resistance plate, and then press the heated parts against each other to facilitate their melting. [0005] Typically, the heating portion is the head surface of the profiled element, suitably cut at 45° to define, for example, a right-angled portion of a corresponding window or door frame. [0006] This method is carried out by means of a welding machine equipped with respective fixing members of the profiled elements which can be brou...
