Definitions
- the present invention relates to a mold for the manufacture of elastic bellows applicable to recovery functions, intended for valves for the dosing of fluid products, such as cosmetic products and the like, contained in containers of variable type, with neck for a cap of closure, to the manufacturing procedure and to the bellows manufactured.
- the objective of the present invention is to achieve a much simpler and more efficient way in the aforementioned recovery bellows, achieving characteristics of greater economy in the manufacturing process and also achieving bellows of said type that have improved elasticity characteristics.
- the present invention foresees the manufacture of said bellows in a single injection phase, without the need for subsequent cutting phases of the upper end, as is currently customary and also allowing highly effective functional characteristics.
- the present invention also relates to the mold used to carry out the molding process of the mentioned recovery bellows as well as to the recovery bellows themselves which have means for increasing the elastic constant thereof.
- the process object of the present invention It takes place in a mold in which movable elements are combined to determine the outer profile of the bellows with a countermold or upper closing plate through which the injection of multiple bellows is made simultaneously from the bottom thereof, so that the upper edge can be determined completely in the same molding operation, without the need for subsequent material trimming.
- the part of the mold itself has a rotating and movable noió to allow the demoulding of the pieces and internally equipped with a cooling chamber.
- the procedure will include placing the mold in position, the lateral closing of the sliders to determine the bellows part, the closing of the upper part flush with the noió, the subsequent injection through an inlet channel through the lower part of the interstitium between the sliders and the noió, subsequently proceeding to the separation of the sliders, lifting the upper closing plate and turning the noió to detach the molded part, after which the mold will be able to restart the work.
- Each of the molded bellows will be finished in the molding operation, and only the injection surplus should be cut.
- the present invention also relates to the bellows manufactured by molding, in which in a traditional helical structure a second V-shaped helical groove is determined centered on the crest of the bellows, thereby achieving a greater resistance of said crest and therefore, a much higher elastic constant of the recovery bellows.
- some drawings of a mold embodiment, manufacturing process and molded bellows according to the present invention are attached by way of explanatory but not limitative example.
- Figures 1 and 2 show two sections of the mold assembly immediately after a molding operation and after the detachment of the molded part.
- Figures 3, 4 and 5 are details of the molded bellows.
- the process object of the present invention takes place with the use of a mold comprising a lower part carrying the noió -1- and a movable upper part -2- carrying the upper mold closing plane -3- and the injection passage -4-.
- the lower mold assembly has two sliding elements arranged in opposition -29- and -5- whose internal profiles, substantially semicircular, -6- and -7- have a conjugate shape respectively of each of the two halves into which the external form of the bellows that you want to manufacture, which has been indicated with the number -8- in the figures.
- the noió -1- presents its upper part -9- corresponding to the internal surface of the bellows -8- and presents in its middle part a filleting -10- that when threaded in the intermediate body -11- of the lower mold, it will allow the demoulding of the piece -8- at the end of the injection cycle, when producing the rotation of the noió -1- on itself by means of a zipper -12- that acts on the longitudinal grooving -13- of the corresponding part of the noió - 1-, which allows axial displacement simultaneously.
- Said noió -1- presents an axial internal chamber -14- that is connected to a cooling water circuit, equipped with a tubular inlet element -15-, complementing with the cooling channels -16- and -17- of the body of the mold, which have their own input and / or output channels -18- and -19- to achieve rapid cooling of the mold and therefore allow a greater working speed in the molding operation.
- bellows assembly -26- has been shown provided with a main helical passage -27- in whose ridges a second helical passage has been made in an inward manner in V -28- so that the bellows turns out to have a double structure to achieve a much higher elastic constant.
