La présente invention concerne l'amélioration technique et pratique d'un dispositif mécanique pour accoupler et désaccoupler le système d'éjection des outillages utilisés pour la transformation par injection des thermoplastiques, des thermodurcissables, des silicones liquides, et des élastomères. The present invention relates to the technical and practical improvement of a mechanical device for coupling and uncoupling the ejection system of the tools used for the transformation by injection of thermoplastics, thermosets, liquid silicones, and elastomers.
L'attelage est traditionnellement effectué soit par un dispositif entièrement mécanique, ce qui nécessite l'intervention d'une personne et une perte de temps, soit par un dispositif totalement hydraulique qui lui ne nécessite pas d'intervention humaine, ni de perte de temps mais oblige à avoir un circuit hydraulique relié aux machines pour le fonctionnement et reste très onéreux à l'achat, ou soit un système complètement pneumatique qui lui non plus ne nécessite pas d'intervention humaine mais il reste cependant aussi onéreux que le système hydraulique car ils sont tous deux entièrement automatisés d'origine. The coupling is traditionally carried out either by a fully mechanical device, which requires the intervention of a person and a loss of time, or by a completely hydraulic device which does not require human intervention, nor loss of time. but requires having a hydraulic circuit connected to the machines for operation and remains very expensive to purchase, or a completely pneumatic system which itself does not require human intervention but it remains however as expensive as the hydraulic system because they are both fully automated from origin.
Le dispositif selon l'invention permet de palier à ces différentes contraintes (coûts et délais d'intervention). The device according to the invention makes it possible to overcome these different constraints (costs and intervention times).
Il comporte en effet un accouplement mécanique et un désaccouplement pneumatique ce qui lui permet d'être beaucoup moins cher tout en restant aussi efficace et indépendant de l'intervention d'une personne. It has indeed a mechanical coupling and a pneumatic uncoupling which allows it to be much cheaper while remaining as effective and independent of the intervention of a person.
Ce dispositif comprend une partie entièrement mécanique (accouplement) sur laquelle vient s'ajouter grâce à deux supports métalliques deux petits vérins pneumatiques pour le désaccouplement. This device includes a fully mechanical part (coupling) to which is added, thanks to two metal supports, two small pneumatic cylinders for uncoupling.
L'accouplement de cette partie mécanique avec le système d'accrochage des outillages (queue d'éjection) se fait par pression, il suffit de venir en appuie sur l'embout et d'exercer une pression pour atteler les deux parties (attelage et embout d'éjection de l'outillage), par compte pour les désaccoupler il faut envoyer de l'air pour faire fonctionner les deux vérins de sorte à faire rentrer les tiges de ces vérins, ceux-ci libèrent alors l'embout d'éjection de l'outillage. The coupling of this mechanical part with the tool attachment system (ejection tail) is done by pressure, it suffices to press on the end piece and exert pressure to couple the two parts (coupling and tool ejection nozzle), by account to uncouple them, air must be sent to operate the two jacks so as to bring in the rods of these jacks, they then release the ejection nozzle of tools.
Les photos annexées illustrent l'invention :
La figure 1 représente le dispositif de l'invention en mode accouplé. The attached photos illustrate the invention:
Figure 1 shows the device of the invention in coupled mode.
La figure 2 représente le dispositif de l'invention en mode désaccouplé. FIG. 2 represents the device of the invention in uncoupled mode.
En référence à ces figures, le dispositif comporte un attelage mécanique (l) sur lequel vient se rajouter deux supports métalliques, un support mobile (2) relié aux vérins (4a et 4b) par l'intermédiaire de deux écrous (6a et 6b) se situant en bout de tige (9a et 9b) et d'un support fixe (3) qui lui est relié à l'aide d'un serrage entre le bout fileté de l'attelage et d'une entretoise (8), ce support (3) comporte lui même deux vérins (4a et 4b), eux même maintenus par quatre écrous (11). With reference to these figures, the device comprises a mechanical coupling (l) on which two metal supports are added, a mobile support (2) connected to the jacks (4a and 4b) by means of two nuts (6a and 6b) located at the end of the rod (9a and 9b) and a fixed support (3) which is connected to it by means of a clamping between the threaded end of the hitch and a spacer (8), support (3) itself comprises two cylinders (4a and 4b), themselves held by four nuts (11).

Pour désaccoupler l'attelage de l'embout d'éjection (5) il faut envoyer de l'air comprimé par les tuyaux (7a et 7b) à l'aide d'un distributeur rotatif (non représenté) afin de faire fonctionner les vérins (4a et 4b).
To disconnect the coupling from the ejection nozzle (5), compressed air must be sent through the pipes (7a and 7b) using a rotary distributor (not shown) in order to operate the jacks (4a and 4b).
Le fait d'envoyer de l'air dans la chambre des vérins cela permet aux tiges (9a et 9b) de rentrer et de tirer en même temps le support mobile (2), ce support mobile (2) en ce déplaçant appui sur la collerette (10) de l'attelage et permet à l'embout (5) de se désaccoupler et de libérer l'éjection de l'outillage. The fact of sending air into the chamber of the jacks this allows the rods (9a and 9b) to enter and pull at the same time the mobile support (2), this mobile support (2) by moving this support on the flange (10) of the coupling and allows the end piece (5) to disengage and release the ejection of the tool.
Selon une variante non illustrée un capteur de proximité peut être ajouter de façon à pouvoir donner une information (accouplé, désaccouplé) à la machine. According to a variant not illustrated, a proximity sensor can be added so as to be able to give information (coupled, uncoupled) to the machine.
A titre d'exemple non limitatif, l'attelage aura des dimensions de l'ordre pour les petits modèles de 110 mm pour la largeur, 60 mm pour la hauteur et 70 mm pour l'épaisseur et pour les grands modèles 150 mm pour la largeur, 100 mm pour la hauteur et 110 mm pour l'épaisseur. By way of nonlimiting example, the coupling will have dimensions of the order for small models of 110 mm for the width, 60 mm for the height and 70 mm for the thickness and for the large models 150 mm for the width, 100 mm for height and 110 mm for thickness.
Les petits modèles auront une force de traction de 24 KN, et les grands modèles auront une force de 32 KN. Small models will have a pulling force of 24 KN, and large models will have a force of 32 KN.
Le dispositif selon l'invention est particulièrement destiné aux attelages pour les outillages qui se montent sur les presses à injecter les plastiques, les silicones et les élastomères.The device according to the invention is particularly intended for couplings for tools which are mounted on injection molding machines for plastics, silicones and elastomers.
