1. A mold for the manufacture of sporting helmets, the mold comprising:
at least one frame defining at least one molding concavity, for molding at least one respective sporting helmet;
at least one counter frame engageable to the frame to hermetically close the respective molding concavity and allow an execution of at least one molding cycle;
wherein the mold comprises at least one intermediate support element for supporting and positioning one or more components of the sporting helmet to be made inside the respective molding concavity of the frame, the intermediate support element having:
a first portion arranged to receive in engagement one or more components of the sporting helmet to be manufactured according to respective predetermined positions;
a second portion facing away from the first portion and having at least one grip handle, for manual positioning of the intermediate support element in the respective molding concavity of the frame and a consequent positioning of the components of the sporting helmet to be manufactured inside said molding concavity, the second portion of the intermediate support element being arranged to be coupled to the respective counter frame;
at least one engagement member for a stable coupling of the intermediate support element to the frame inside the respective molding concavity, the engagement member being operatively interposed between the intermediate support element and the respective molding concavity of the frame;
at least one engagement constraint for the stable coupling of the intermediate support element to the counter frame, the engagement constraint being operationally interposed between the intermediate support element and the counter frame.
 
14. A process for molding sporting helmets, in particular cycling helmets, comprising the steps of:
providing at least one frame of a mold defining at least one molding concavity, for molding at least one respective sporting helmet;
preparing at least one counter frame of the mold engageable to the frame to hermetically close the respective molding concavity and allowing an execution of at least one molding cycle;
preparing at least an intermediate support element for supporting and positioning one or more components of the sporting helmet to be manufactured inside the respective molding concavity of the frame of the mold;
placing one or more components of the sporting helmet to be manufactured in a first portion of the intermediate support element according to respective predetermined positions;
positioning the intermediate support element inside the respective molding concavity of the mold frame with the first portion facing said molding concavity to position the components of the sporting helmet to be manufactured in the respective molding concavity according to respective predetermined positions;
blocking the intermediate support element inside the respective molding concavity according to the previously determined position;
engaging the counter frame of the mold to the frame of the same to hermetically close the respective molding concavity in correspondence with a second portion of the intermediate support element opposite the first portion;
starting a molding cycle by injecting a corresponding molding material;
disengaging the counter frame of the mold from the frame of the same to access the respective molding concavity and the respective intermediate support element, when the molding cycle is completed;
releasing the intermediate support element from the respective molding concavity;
removing the intermediate support element from the respective molding concavity of the frame of the mold together with the respective manufactured sporting helmet;
separating the intermediate support element from the respective manufactured sporting helmet;
repeating the process again.
