The device is constituted by a hopper 1 fitted with a pressure-withstanding lid 2. A pressurised gas tends to push the polymer concrete through the injection orifice 3 of the hopper. The polymer concrete fills the mould 5 and 6 up to a gasket 7. Indicators 8 make it possible to ensure that the mould is completely filled. The device according to the invention is particularly intended for the manufacture of sanitary ware, tiling, various components for a dwelling and for urban furniture.

Description

La présente invention concerne un dispositif pour injecter un béton de résine ou marbre synthétique a base de résine de synthèse et de charges minérales (silice, carbonate de calcium etc..) dans un moule pour permettre le remplissage de ce dernier. The present invention relates to a device for injecting a resin concrete or synthetic marble based on synthetic resin and mineral fillers (silica, calcium carbonate etc.) in a mold to allow the filling of the latter.

Les moules representant les pièces à fabriquer sont traditionnellement remplis par coulée à la pression attlosphérique les moules étant soumis à une vibration. The molds representing the parts to be manufactured are traditionally filled by casting at attlospheric pressure, the molds being subjected to a vibration.

Ce procédé présente plusieurs inconvénients qui sont - mauvaise homogénéité du produit fini dù à la présence de
nombreuses petites bulles d'air - presence de bulles d'air importante sur la face arrière des
produits finis - durée de remplissage et de débullage importante - épaisseur des paroies importantes afin de permettre l'dcou-
lement par granité du béton de résine et simultanément
l'échappement et la remontée des bulles d'air.This process has several disadvantages which are - poor homogeneity of the finished product due to the presence of
many small air bubbles - presence of large air bubbles on the back of the
finished products - significant filling and boiling time - thickness of the large walls in order to allow
by granularity of the resin concrete and simultaneously
exhaust and rising air bubbles.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

Selon une forme de réalisation préférentielle il comporte en partie supérieure une trémie étanche avec couvercle dans laquelle est versé le béton de résine ou marbre de synthèse. According to a preferred embodiment, it comprises in the upper part a sealed hopper with cover into which the resin concrete or synthetic marble is poured.

Après fermeture du couvercle une prcssion d'air ou gaz comprimé est introduite qui tend à pousser le béton de résine à travers l'orifice d'injection en partie basse de la trémie. After closing the cover a pressure of compressed air or gas is introduced which tends to push the resin concrete through the injection orifice in the lower part of the hopper.

Cet orifice est raccordé à un moule selon l'importance de la pièce à réaliser il peut y avoir un seul ou plusieurs points d'injection. This orifice is connected to a mold depending on the size of the part to be produced, there may be one or more injection points.

Le moule est constitué- de deux parties une intérieure, l'autre extérieure, qui définissent les formes de la pièces. The mold consists of two parts, one interior, the other exterior, which define the shapes of the part.

Les deux parties du moule sont sérrées l'une contre l''autre par un dispositif mélanique ou pneumatique; un joint: plastique assure l'étanchéité entre ces deux parties. The two parts of the mold are tightened one against the other by a melanic or pneumatic device; a seal: plastic seals between these two parts.

Le moule étant soumis à des vibrations, le béton est injecté dans le moule. The mold being subjected to vibrations, the concrete is injected into the mold.

En fonction de la viscosité du béton de résine et de l'espace entre les deux parties du moule il est parfois nécéssaire de créer un vide partiel dans le moule. Depending on the viscosity of the resin concrete and the space between the two parts of the mold, it is sometimes necessary to create a partial vacuum in the mold.

Des témoins, positionnés aux extrémités du moule, permettent de visualiser le remplissage complet de celui-ci.  Witnesses, positioned at the ends of the mold, show the complete filling of the mold.

Selon une première variante, la trémie sous pression peut être constituée de deux parties, une partie intérieure recevant le béton de résine et une partie extérieure supportant la pression. According to a first variant, the pressure hopper can consist of two parts, an inner part receiving the resin concrete and an outer part supporting the pressure.

Cette variante facilite le nettoyage et la manipulation de la partie recevant le béton de résine. This variant facilitates cleaning and handling of the part receiving the resin concrete.

Selon une seconde variante, la trémie sous pression peut être remplacée par une pompe péristaltique assurant la mise en pression du béton de résine. According to a second variant, the pressure hopper can be replaced by a peristaltic pump ensuring the pressurization of the resin concrete.

Cette variante est principalement intéressante en cas de pièces de grande volume. This variant is mainly interesting in the case of large volume parts.

de ce dispositif - La figure 3 : représente, en coupe, une seconde variante de
ce dispositif
Le dispositif représenté sur la figure 1 comporte une trémie supérieure (1) munie d'un couvercle (2) l'ensemble étant conçu pour résister à la pression.- Figure 1: shows, in section, the device according to
the invention - Figure 2: shows, in section, a first variant
of this device - Figure 3: shows, in section, a second variant of
these measures
The device shown in Figure 1 comprises an upper hopper (1) provided with a cover (2) the assembly being designed to withstand the pressure.

Le béton de résine ou marbre de synthèse est poussée sous pression par un gaz, de préférence de l'air comprimé. Resin concrete or synthetic marble is pushed under pressure by a gas, preferably compressed air.

Le béton sort sous pression de la trémie par l'orifice inférieure (3) et est injecté dans le moule par buse d'injection (4). The concrete exits under pressure from the hopper through the lower orifice (3) and is injected into the mold by injection nozzle (4).

Le moule comporte deux parties (5) et (6) déterminant la forme de la pièce à réaliser. The mold has two parts (5) and (6) determining the shape of the part to be produced.

L'étanchéité entre ces 2 parties est réalisée par un joint plastique (7). The seal between these 2 parts is achieved by a plastic seal (7).

Des témoins (8) à l'extrémité du moule permettent de controler la fin du remplissage du moule. Indicators (8) at the end of the mold make it possible to control the end of the filling of the mold.

Dans la forme de réalisation selon la figure 2, la trémie supérieure est en 2 parties : une partie intérieure (9) légère contenant le béton de résine et une partie extérieure (10) robuste, résistant à la pression, sur laquelle est articulée un couvercle (11). In the embodiment according to Figure 2, the upper hopper is in 2 parts: a light inner part (9) containing the resin concrete and a robust, pressure-resistant outer part (10), on which is hinged a cover (11).

Les deux parties sont assemblées en partie basse par un dispositif d'étanchéité à portée conique (12). The two parts are assembled in the lower part by a sealing device with a conical bearing (12).

Dans la forme de réalisation selon la figure 3 le béton de résine placé dans la trémie supé-rieure (13) est mis en pression par une pompe péristaltique constituée d'un manchon déformable (14) écrasé par des galets mis en rotation inverse (15). In the embodiment according to Figure 3 the resin concrete placed in the upper hopper (13) is pressurized by a peristaltic pump consisting of a deformable sleeve (14) crushed by rollers set in reverse rotation (15 ).

Le dispositif selon l'invention permet - de réaliser des pièces pratiquement exemptes de bulles aussi
bien dans la masse du produit que dans ses faces arrières; - un remplissage plus rapide et une suppression du temps de
débullage ce qui permet un cycle de production beaucoup
plus court.The device according to the invention makes it possible - to produce parts practically free of bubbles also
both in the mass of the product than in its rear faces; - faster filling and elimination of the
boiling which allows a production cycle a lot
shorter.

- de réaliser des pièces dont les paroies sont minces.- to produce parts with thin walls.

Le dispositif selon l'invention est particulièrement destiné à la fabrication d'appareils sanitaire, de dessus de tables, de bacs à fleurs, d'appuis de fenêtre; de monuments funéraires, de carrelages, en béton de résine ou marbre de synthèse.  The device according to the invention is particularly intended for the manufacture of sanitary appliances, table tops, flower boxes, window sills; funerary monuments, tiles, resin concrete or synthetic marble.
