The main cavity (4) comprises a deflecting element (7) extending within the cavity (4) itself for deviating the metal alloy towards the secondary cavity (6).
Description
- The present invention relates to a mold for manufacturing toothed sprockets for locking winding rollers of safety belts.
- The invention also pertains to a process for manufacturing toothed sprockets.
- It is known that rewinding rollers for safety belts, of the type commonly used on motor-vehicles for example, usually comprise a toothed sprocket essentially including a disc-shaped element carrying a circumferential toothing, which is coaxially associated with a winding roller of the safety belt. Rotation of the sprocket is locked when, upon intervention of an accelerometer operating device, a toothed fork is brought to a working condition of mutual meshing with the sprocket toothing.
- Since the toothed sprocket is a component on which persons' safety relies in case of accident, strict parameters must be observed in terms of geometric and dimensional tolerance, to supply suitable reliability guarantees in time.
- These requirements are presently met by making the toothed sprockets of an aluminum alloy molded by pressure die-casting.
- In detail, die-casting is carried out through injection of a molten aluminum alloy into a mold in which a plurality of molding cavities or so-called “mold impressions” are defined, each corresponding to a toothed sprocket to be obtained, mutually connected by runners opening into at least one aperture or gate for admission of molten metal.
- These runners each communicate with the molding cavity at a peripheral circumferential region of the cavity itself adapted to define the toothing of the respective sprocket.
- In this way, the molten metal is introduced into each cavity through a respective runner along an injection path substantially perpendicular to the longitudinal extension axis of the toothed sprocket. Once introduced into the molding cavity, the molten metal flows along a predetermined path filling the whole cavity so as to conform in shape to the cavity itself.
- However, many difficulties have been found in obtaining toothed sprockets in which the presence of tailpieces projecting at right angles from the disc-shaped body is required, for example for supporting and/or mechanically cooperating with other components of the rewinding device of the safety belt.
- In fact, these tailpieces having an extension parallel to the longitudinal axis of the sprocket, are not formed in a correct manner because the molten metal does not successfully fill the cavities formed in the molds in order to obtain said tailpieces.
- In this regard the Applicant has noticed that during the die-casting step the molten metal tends to follow the main cavity of the mold according to the path imposed by the runners, and it does not always succeed in efficiently filling the secondary cavities extending transversely of said path, before the metal solidifies.
- Also when said secondary cavities are filled with molten metal, the latter does not flow thereinto with the required pressure, thereby generating tailpieces internally having air bubbles weakening their structure.
- In the light of the above, it is an object of the present invention to provide a process and a mold for manufacturing toothed sprockets for locking winding rollers of safety belts capable of solving the above mentioned drawback.
- In particular, it is an object of the present invention to propose a process and a mold for manufacturing toothed sprockets for locking winding rollers of safety belts, capable of ensuring a better filling of the mold, so as to enable projecting portions or tailpieces having optimal mechanical features to be obtained.
- The technical task mentioned and the objects specified are substantially achieved by a process and a mold for manufacturing toothed sprockets for locking winding rollers of safety belts according to the features recited in the appended claims.
- More particularly, the invention proposes a process for manufacturing a toothed sprocket for locking winding rollers of safety belts, comprising the steps of: providing a mold having a main cavity defining at least one toothed disc-shaped body and at least one secondary cavity, brought into fluid communication with the main cavity so as to define a tailpiece jutting out of said toothed disc-shaped body; die-casting a molten metal alloy in said main cavity along a filling path of same;
- wherein during the die-casting step at least part of the molten metal alloy meets at least one deflecting element provided along the filling path for deviating the alloy towards said secondary cavity.
- According to a further aspect, the invention proposes a mold for manufacturing toothed sprockets for locking winding rollers of safety belts, comprising: a main cavity adapted to be filled with a molten metal alloy so as to define at least one toothed disc-shaped element having a toothing on a peripheral surface thereof; and at least one secondary cavity brought into fluid communication with said main cavity, so as to define a tailpiece jutting out of the disc-shaped body; characterized in that it comprises at least one deflecting element extending within the main cavity for deviating the metal alloy towards said secondary cavity.

FIGS. 2 and 3 , thetoothing 101 ofsprocket 100 is circumferentially distributed on the periphery of a disc-shaped body 102 which preferably extends radially away from a cylindricalcentral portion 103. - Said
central portion 103 is rigidly connected to a rotating member of the winding device. In the embodiment shown, the cylindricalcentral portion 103 has a through central hole comprising a plurality ofgrooves 104 intended for coupling with respective mating toothing series provided on a hub or shaft carried by a winding roller of safety belts. -
Sprocket 100 further comprises one or more tailpieces 105 (two tailpieces in the preferred embodiment) extending perpendicular to, or in any case transversely of a diametrical plane of the disc-shaped body 102 carryingtoothing 101, as shown inFIG. 2 . -
Mold 1 is adapted to make asprocket 100 of the above described type which comprises afirst half 2 and asecond half 3 havingrespective surfaces main cavity 4. - The shape of the
main cavity 4 ofmold 1 matches the shape of at least the sprocket portion consisting of theradial toothing 101 and the disc-shaped body 102. - In the preferred embodiment, the shape of the
main cavity 4 further matches the shape of thecylindrical portion 103 of thetoothed sprocket 100. - In this way, through die-casting of a molten metal, preferably an aluminum alloy, into the
main cavity 4, toothing 101, disc-shaped body 102 andcylindrical portion 103 ofsprocket 100 can be defined. - In this regard,
mold 1 comprises aninjection runner 5 radially opening into themain cavity 4 at agate 5 a in a direction X substantially parallel to the diametrical extension plane of themain cavity 4, as shown inFIG. 1 . - To make said
tailpieces 105 jutting out ofsprocket 100,mold 1 further comprises onesecondary cavity 6 for eachtailpiece 105. - In particular, each
secondary cavity 6 is fully formed in the first 2 and second 3 halves and is brought into fluid communication with themain cavity 4. - The
secondary cavity 6 has a longitudinal extension direction oriented transversely of a diametrical extension plane of themain cavity 4. - The metal alloy die-cast through the
injection runner 5 passes through thegate 5 a in the extension direction X of the injection runner, and spreads in themain cavity 4 following a filling path represented just as an indication by arrow P inFIG. 1 . - Advantageously, to ensure correct and efficient filling of the
secondary cavity 6 thereby giving thetailpieces 105 ofsprocket 100 the necessary mechanical features,mold 6 comprises a deflecting element 7 extending in themain cavity 4 along the filling path P. - In more detail, the deflecting element 7 is disposed in front of
gate 5 a, along the extension direction X of theinjection runner 5. Consequently, at least part of the metal alloy die-cast along the entry path P meets the deflecting element 7 and is therefore deviated in a direction transverse to the diametrical extension plane of themain cavity 4, i.e. towards thesecondary cavity 6. - In the preferred embodiment shown in

surface 3 a ofhalf 3 ofmold 1. Consequently, the presence of the deflecting element 7 creates arecess 106 shown inFIG. 3 , in the disc-shaped body 102 ofsprocket 100, attailpiece 105. Thisrecess 106 can be easily identified and denotes the presence of the deflecting element 7 inmold 1. - When the molten metal alloy has been die-cast into
