Problems solved by technology

In fact, the structures of the objects obtained by this known device are usually not very compact and they have clear burrs whose removal requires expensive finishing operations
Basically, this known device needs to be stopped only after a few machining cycles in order to then be able to start again after the preparation step, which is unacceptable in the normal operation of the device in an industrial production process

Embodiment Construction

[0018] With reference to the drawings, the device according to the invention for the manufacture of articles of light alloy or similar material comprises a mold, indicated in its entirety by the reference numeral 10 . Purely by way of example, the apparatus shown in the figures will manufacture multiple toe caps for safety shoes in a single molding operation.

[0019] The mold 10 comprises a lower mold half 12 and an upper mold half 14 , both metallic, capable of being joined together in the closed configuration of the mold 10 .

[0020] In particular, the lower mold half 12 will be detachably fixed on a support plane determined by a press (not shown in the figures, since it is of a known type per se) which enables the upper mold half 14 to be placed on the mold 10. The vertical movement during the closing and opening steps of the mold simultaneously applies pressure to the two halves of the mold.

[0021] A mold half 12 is passed at a substantially central position by a vert...

Abstract

An apparatus for manufacturing items of light alloy or similar comprises a mould (10) that includes two half-moulds (12, 14), lower and upper, able to be coupled together. The lower half-mould (12) defines a moulding cavity (20) adjacent to a supply duct (16) of liquid metal that passes through it up to an introduction passage (18) of the liquid metal in the moulding cavity (20). The upper half-mould (14) is associated with at least one moveable punch (24) provided with a moulding surface (21) that defines the shape of an item to be moulded together with the moulding cavity (20). Each punch (24) performs the function of a shutter to stop the flow of liquid metal towards the moulding cavity (20). The apparatus includes temperature control means and temperature sensors connected with a control unit (32) that prevents the movement of the moveable punches (24) if the temperature of both half-moulds (12, 14) is not comprised within a predetermined range of values.

Description

technical field [0001] The present invention generally relates to devices for the manufacture of objects of light alloys, such as aluminum alloys, aluminum alloys and the like. [0002] More specifically, the invention relates to a device of the type stated in the preamble of appended claim 1 . Background technique [0003] EP-1472027 describes such a device, which performs a "liquid metal forging" process, also known as "squeeze casting". This known device basically comprises a lower mold half, which can be connected together, and at least one upper mold half, the lower mold half being passed through by a liquid metal introduction duct, which is connected to the Below the metal melting furnace connection. In the lower mold half, at least one lower cavity is defined near the edge of the liquid metal introduction conduit, the lower cavity having a concave portion that will receive a quantity of liquid metal that is supplied through said conduit, And dose by spilling from t...
