DESCRIZIONE DESCRIPTION
dell?invenzione avente per TITOLO ?Stampo per realizzare una gruccia munita di mozzi" of the invention with the TITLE ?Mould for making a hanger equipped with hubs"
Il presente trovato riguarda uno stampo per realizzare una gruccia munita di mozzi, atti a supportare un?asta portapantaloni o coppie di ganci sagomati, secondo la parte generale della rivendicazione 1. The present invention relates to a mold for making a hanger equipped with hubs, suitable for supporting a trouser hanger rod or pairs of shaped hooks, according to the general part of claim 1.
Fra i diversi tipi di appendini di tipo noto sono diffuse le grucce composte da una struttura rigida ad arco con gancio centrale, atta a sorreggere capispalla, quali giacche, camicie o altri capi di abbigliamento, e da una sottostante asta cosiddetta ?portapantaloni? o da coppie di ganci sagomati. Among the different types of hangers of the known type, hangers are widespread which are composed of a rigid arched structure with a central hook, suitable for supporting outerwear, such as jackets, shirts or other items of clothing, and of a so-called ?trouser hanger? or by pairs of shaped hooks.
Di norma la gruccia presenta una sezione ad ?U? rovesciato e viene realizzata mediante un?operazione di stampaggio per iniezione di materiale vario, dalla plastica al biologico. Normally the hanger has a ?U? reversed and is made by means of an injection molding operation of various materials, from plastic to organic.
Solitamente, nelle grucce pi? economiche, la struttura ad arco e l?asta portapantaloni costituiscono un unico blocco stampato. Usually, in the hangers pi? economic, the arched structure and the trouser hanger rod form a single molded block.
Di contro, nelle grucce di qualit? superiore, oppure quando l?appendino presenta una sezione ad ?U? ed ? quindi conveniente posizionarlo nello stampo ?in verticale?, in modo tale che per ottenere ?il corpo? dell?appendino stesso non servano movimenti (effettuati da appositi carrelli) nello stampo, il corpo arcuato e l?asta portapantaloni costituiscono due elementi che vengono stampati separatamente e successivamente assemblati. On the other hand, in quality hangers? upper, or when the hanger has a ?U? and ? therefore it is convenient to position it in the mold ?vertically?, in such a way that in order to obtain ?the body? of the hanger itself does not require movements (carried out by special trolleys) in the mold, the arched body and the trouser hanger rod constitute two elements which are molded separately and subsequently assembled.
Allo stato attuale della tecnica, l?assemblaggio corpo arcuato/asta portapantaloni o coppie di ganci sagomati avviene mediante due tipi di aggancio. In the current state of the art, the assembly of the arched body/trouser rod or pairs of shaped hooks takes place by means of two types of hooking.
In una prima forma di realizzazione, l?aggancio si realizza mediante la creazione, al di sotto del corpo arcuato, di due sporgenze, riconducibili a due gancetti laterali, ognuno costituito da una lamella dove ? definita una costola che termina con un uncino (a titolo di esempio si citano le figg. 20-21, riff. 100-102 del documento brevettuale n. 102019000010392, di cui ? titolare la medesima richiedente della presente domanda, nel quale viene anche descritta una attrezzatura per lo stampaggio e dove, la lamella 100, presentando uno spessore ridotto, permette di ricavare la sua impronta sulla superficie laterale di uno degli estrattori (figg. 2-3, riff. 1-P)). In a first embodiment, the coupling is achieved by creating, below the arched body, two protrusions, which can be traced back to two lateral hooks, each consisting of a blade where ? defined as a rib that ends in a hook (as an example cited are figs. 20-21, refs. 100-102 of patent document n. 102019000010392, owned by the same applicant of the present application, in which it is also described a molding fixture and where, the reed 100, having a reduced thickness, allows its imprint to be obtained on the lateral surface of one of the extractors (figs. 2-3, ref. 1-P)).
In alternativa, quando la zona di aggancio non deve sporgere inferiormente dalla sagoma del corpo arcuato, l?aggancio si realizza mediante la creazione, al di sotto del corpo arcuato, di due mozzi costituiti da un corpo sostanzialmente cilindrico forato centralmente, che presenta sulla sua superficie laterale delle aperture sagomate, in modo da costituire dei sottosquadri che permettono l?agganciamento a ?clip? delle estremit? sagomate dell?asta portapantaloni o della coppia di ganci sagomati. Alternatively, when the hooking area must not protrude downwards from the shape of the arched body, the hooking is achieved by creating, below the arched body, two hubs consisting of a substantially cylindrical body with central hole, which has on its lateral surface of the shaped openings, so as to form undercuts that allow the hooking to ?clip? of the extremities? shaped of the trouser hanger rod or of the pair of shaped hooks.
Allo stato attuale della tecnica, per realizzare grucce munite dei due mozzi come quelle sopra descritte, oltre alla comune attrezzatura composta da due piastre (matrici), fra le quali viene iniettato il materiale per realizzare il corpo arcuato, ? necessario impiegare dei carrelli supplementari, delle aste inclinate o elastiche o altri meccanismi, per poter realizzare anche i mozzi muniti delle aperture sagomate a sottosquadro, ci? che comporta numerosi svantaggi sia operativi che economici (essi sono di complicata realizzazione, sono ingombranti e richiedono una adeguata manutenzione, che rende complessa la produttivit? dell?intero stampo). In the current state of the art, in order to make hangers equipped with two hubs like those described above, in addition to the common equipment consisting of two plates (matrixes), between which the material to make the arched body is injected, ? It is necessary to use additional trolleys, inclined or elastic rods or other mechanisms, in order to be able to also make the hubs equipped with undercut shaped openings, what? which involves numerous operational and economic disadvantages (they are complicated to make, they are bulky and require adequate maintenance, which makes the productivity of the entire mold complex).
Scopo principale del presente trovato ? quello di realizzare uno stampo per la produzione di grucce munite di mozzi dotati di aperture laterali a sottosquadro, che risulti privo degli inconvenienti manifestati dai dispositivi consimili di tipo noto. Main purpose of the present invention ? that of realizing a mold for the production of hangers provided with hubs provided with lateral undercut openings, which does not have the drawbacks manifested by similar devices of known type.
Specificatamente, scopo del trovato ? quello di realizzare uno stampo per la produzione di grucce munite di mozzi dotati di aperture laterali a sottosquadro che non richieda l?utilizzo di carrelli supplementari, aste inclinate o elastiche o altri meccanismi consimili. Specifically, the purpose of the invention ? that of realizing a mold for the production of hangers equipped with hubs equipped with undercut side openings which does not require the use of supplementary carriages, inclined or elastic rods or other similar mechanisms.
Sempre specificatamente, scopo del trovato ? quello di realizzare uno stampo per la produzione di grucce munite di mozzi dotati di aperture laterali a sottosquadro che utilizzi, senza bisogno di modifiche, degli stampi di tipo noto, composti da due piastre di forma sovrapposte e dai perni di guida di dette piastre e di estrazione del pezzo stampato dalla matrice. Again specifically, the purpose of the invention? that of making a mold for the production of hangers equipped with hubs equipped with undercut side openings which uses, without the need for modifications, molds of the known type, made up of two overlapping shaped plates and the guide pins of said plates and extraction of the molded piece from the matrix.
Ulteriore scopo del trovato ? quello di realizzare uno stampo che risulti di semplice e rapido impiego e non richieda una frequente manutenzione, Further purpose of the invention ? that of making a mold that is simple and quick to use and does not require frequent maintenance,
Tali scopi sono raggiunti mediante uno stampo che impiega delle normali piastre di forma reciprocamente sovrapposta le quali, a stampo chiuso, definiscono la sagoma del corpo arcuato, che prevede il fatto che la cava che definisce l?impronta completa del mozzo sia ricavata sulla piastra inferiore, nonch? l?impiego di uno spinotto (equiparabile ad un vero e proprio perno di estrazione, poich? di fatto lo ?), che riporta nella parte superiore le sporgenze corrispondenti alle aperture a sottosquadro da realizzare nel mozzo stesso. These aims are achieved by means of a mold which uses normal mutually superimposed plates which, when the mold is closed, define the shape of the arched body, which provides for the hollow which defines the complete footprint of the hub to be obtained on the lower plate , as well as the use of a pin (comparable to a real extraction pin, since in fact it is), which shows in the upper part the protrusions corresponding to the undercut openings to be made in the hub itself.
Detto spinotto, costituito da un solo corpo astiforme prolungato cilindrico (o di forma ovale o di forma consimile), ? scorrevole all?interno della piastra inferiore e disposto in modo parallelo ai perni di estrazione, in modo da inserirsi all?interno della cava che delimita il mozzo, in posizione tangente alla parete esterna di detta cava. Said piston pin, consisting of a single rod-like extended cylindrical body (or oval or similar shape), ? sliding inside the lower plate and arranged parallel to the extraction pins, so as to fit inside the slot which delimits the hub, in a tangent position to the external wall of said slot.
Con tale disposizione, a stampo chiuso, il materiale iniettato va a riempire, oltre che la cava che definisce il corpo arcuato, anche la cava che definisce il mozzo, dove sono presenti le sporgenze dello spinotto necessarie per realizzare le aperture laterali a sottosquadro. With this arrangement, with the mold closed, the injected material fills not only the slot which defines the arched body, but also the slot which defines the hub, where there are the protrusions of the pin necessary to make the side undercut openings.
Di seguito lo stampo si apre e con la fuoriuscita dei perni di estrazione e degli spinotti si espelle l?intera gruccia stampata. The mold then opens and the entire molded hanger is expelled with the extraction pins and pins coming out.
Il trovato verr? meglio definito mediante la descrizione di una sua possibile forma di realizzazione, resa a solo titolo di esempio non limitativo, con l?aiuto delle tavole di disegno allegate, dove: The found will come better defined through the description of one of its possible embodiments, given only as a non-limiting example, with the help of the attached drawings, where:
- la fig.1 (tav. I) rappresenta una vista dello stampo di cui al trovato in posizione aperta; - fig.1 (tab. I) represents a view of the mold according to the invention in the open position;
- la fig.2 rappresenta una vista di detto stampo chiuso ed in fase di iniezione del materiale; - la fig. 3 rappresenta due viste, rispettivamente, di detto stampo aperto dopo l?iniezione del materiale e la gruccia stampata: - fig.2 shows a view of said mold closed and in the material injection phase; - fig. 3 represents two views, respectively, of said mold opened after the injection of the material and of the molded hanger:
- la fig.4 (tav. II) rappresenta una vista della sezione, secondo la linea IV-IV di fig.2; - fig.4 (tab. II) represents a view of the section, along line IV-IV of fig.2;
- la fig.5 rappresenta delle viste, frontale e laterale dello spinotto; - fig.5 is a front and side view of the pin;
- la fig.6 rappresenta due diverse viste (a, b) delle aperture a sottosquadro sul mozzo. - fig.6 represents two different views (a, b) of the undercut openings on the hub.
Di norma, lo stampo per realizzare la gruccia, indicata con il riferimento 100, ? costituita da un corpo ?K? munito di due mozzi, indicati con il riferimento 10, forati centralmente, che presentano sulla superficie laterale 11 delle aperture sagomate a sottosquadro 12, si compone di due piastre, indicate con i riferimenti F1 e F2, disposte reciprocamente sovrapposte, che variano da una posizione reciprocamente accostata (stampo chiuso) per definire la sagoma del pezzo da stampare, mediante iniezione di materiale, ad una posizione reciprocamente distanziata (stampo aperto) per permettere ai perni di estrazione P, scorrevoli con direzione parallela alla direzione di apertura dello stampo, di realizzare l?estrazione del pezzo stampato dalla matrice, il tutto come in s? noto. As a rule, the mold for making the hanger, indicated with the reference 100, is constituted by a body ?K? provided with two hubs, indicated with the reference number 10, centrally drilled, which have on the lateral surface 11 undercut shaped openings 12, it consists of two plates, indicated with the reference numbers F1 and F2, arranged mutually superimposed, which vary from one position mutually approached (closed mould) to define the shape of the piece to be moulded, by injection of material, at a mutually spaced position (open mould) to allow the extraction pins P, sliding in a direction parallel to the opening direction of the mould, to create the extraction of the molded piece from the matrix, all as in s? known.
La novit? del trovato consiste nel fatto di prevedere che una cava 20 che definisce l?impronta completa del mozzo sia ricavata sulla piastra inferiore F1 e di prevedere l?impiego di uno spinotto 30, che riporta nella parte superiore delle sporgenze 31, corrispondenti alle aperture sagomate a sottosquadro 12 da realizzare nel mozzo stesso. The news? of the invention consists in providing that a hollow 20 which defines the complete impression of the hub is obtained on the lower plate F1 and in providing for the use of a pin 30, which bears in the upper part some protrusions 31, corresponding to the shaped openings undercut 12 to be made in the hub itself.
Lo spinotto 30, scorrevole all?interno della piastra inferiore F1 e disposto in modo parallelo ai perni di estrazione, si inserisce con le sporgenze 31 all?interno della cava 20 che delimita il mozzo 10 (vedi fig. 1). The pin 30, sliding inside the lower plate F1 and arranged parallel to the extraction pins, fits with the protrusions 31 inside the hollow 20 which delimits the hub 10 (see fig. 1).
Con tale disposizione (vedi figg. 2 e 4) a stampo chiuso, il materiale iniettato va a riempire, oltre che la cava che stampa il corpo arcuato K, anche la cava 20 che stampa il mozzo 10, dove, essendo presente in detta cava 20 la sporgenza 31 dello spinotto 30, si realizza il sottosquadro 12 sul suddetto mozzo 10. With this arrangement (see figs. 2 and 4) with the mold closed, the injected material fills not only the hollow which molds the arched body K, but also the hollow 20 which molds the hub 10, where, being present in said hollow 20 the protrusion 31 of the gudgeon pin 30, the undercut 12 is made on the aforementioned hub 10.
Di seguito lo stampo si apre e con la fuoriuscita dei perni di estrazione P e degli spinotti 30, si espelle l?intera gruccia stampata 100 (vedi fig. 3). The mold then opens and with the extraction pins P and the pins 30 coming out, the entire molded hanger 100 is expelled (see fig. 3).
Come visibile nella fig. 6, le aperture sagomate a sottosquadro 12, realizzate sul corpo del mozzo 10, ottenute con le sporgenze 31, sono riconducibili a due tipi: a profilo chiuso 12.1 (riconducibile sostanzialmente ad un foro) e ad intaglio laterale 12.2, dove al foro viene associato un canale con sottosquadro conformato, preferibilmente, a ?coda di rondine?. As visible in fig. 6, the undercut shaped openings 12, made on the body of the hub 10, obtained with the protrusions 31, can be traced back to two types: with a closed profile 12.1 (substantially attributable to a hole) and with lateral notch 12.2, where the hole is associated a channel with an undercut preferably shaped like a "dovetail".
Inoltre, si specifica che una singola apertura sagomata o una pluralit? di aperture sagomate a sottosquadro 12 possono essere posizionate sul mozzo 10 rivolte in qualunque direzione, preferibilmente, con direzione verso l?interno (come rappresentato nei disegni) o verso l?esterno della gruccia. Furthermore, it is specified that a single shaped opening or a plurality? of undercut shaped openings 12 can be positioned on the hub 10 facing in any direction, preferably towards the inside (as shown in the drawings) or towards the outside of the hanger.
Ovviamente, lo stampo pu? assumere dimensioni e conformazioni svariate, in funzione del tipo di gruccia da produrre, purch? il tutto rientri nel concetto inventivo definito dalle seguenti rivendicazioni. Obviously, the mold can? take on various dimensions and conformations, depending on the type of hanger to be produced, as long as? all of which falls within the inventive concept defined by the following claims.
