Definitions
- the present invention relates to the technical field of structural and semi-structural parts of a motor vehicle, in particular, but not exclusively, to motor vehicle front surfaces.
- the sealing of the mold is provided by a portion of the wall of the mold in cooperation with the crosspiece.
- the cross member forms an integral part of the overmoulded part obtained and therefore must not be subjected to too much pressure, to prevent its degradation.
- the plastic material brought under pressure inside the mold tends to escape towards the outside of the mold, in particular when the pressure in the mold is high, for example during the compacting phase of the injection molding. Leakage of material towards the outside of the mold causes a degradation of the quality of the overmolded part.
- the object of the invention is to remedy this drawback.
- the subject of the invention is an assembly of a mold and a cross-member of a motor vehicle, the cross-member comprising a portion to be overmoulded intended to be placed in the mold, a part intended to be located outside of the mold and at least one receiving zone of at least one wall portion of the mold, interposed between these two parts.
- the wall portion of the mold and the receiving zone are substantially complementary in shape and the cross member has at least one unevenness in the receiving zone, preferably at least two unevennesses, with respect to a reference surface along the general contour of the crosses.
- part intended to be located outside the mold is meant a part which is not intended to be inside a molding chamber of the mold. This part may however not be literally outside the mold and may be for example in an empty chamber thereof, as shown for example in Figure 1.
- the wall portion of the mold is substantially complementary to the receiving zone, which means that, when the receiving zone has a given unevenness, the wall portion of the mold has a difference in level with that of the receiving zone, less some of the unevenness of the crossbar may have a difference in inclination with the corresponding unevenness of the mold.
- the “reference surface” follows the general outline of the crossbar, which means that it does not take into account the local variations of its shape.
- the reference surface has another shape, for example if it is spherical, the level of a given point is measured with respect to the reference surface in a direction normal to a plane tangent to the reference surface. this point.
- the unevenness of the receiving zone therefore makes it possible, for a given width of the wall of the mold, to lengthen the path that the material must travel through to exit the mold, which makes it possible to increase the pressure losses experienced by the leaks of the mold. material.
- the invention makes it possible to greatly reduce the speed of the plastic material leaking out of the mold by lengthening and disturbing with changes of direction the path of the plastic material in the passage formed between the wall of the mold and the cross-member.
- each receiving zone of a wall portion of the mold comprises at least one projection or a cavity.
- Each projection or cavity comprising two unevennesses, each receiving zone then comprises two unevennesses. Two zones of reception of the wall of the mold are distinct when they are separated by the portion to be overmolded of the cross-member. The path of the material out of the mold is thus still elongated and there is less material leakage out of the molding chamber;
- the projection or the cavity is situated at a distance from a longitudinal end of the crossmember
- the projection or the cavity is of transverse dimension, measured in the longitudinal direction of the crossmember, at least ten times smaller than the longitudinal dimension of the crossmember, the crossmember has at least one slope at the edge of the reception zone.
- the mold and the cross member being of essentially complementary shape, this makes it possible to increase the length of the path to be traveled by the material without significantly modifying the shape of the wall of the mold; -
- the cross is made of a thermosetting material, especially in AMC
- the cross has several uneven slopes each formed in one or other of its receiving zones, substantially constant slopes and parallel to each other, each of these slopes being preferably parallel to a demolding direction of the mold.
- substantially parallel slopes are slopes with a difference in inclination of the order of magnitude of a draft angle for demolding the mold, that is to say a difference in inclination less than 2 °.
- the mold must allow overmolding on the cross member a constant outer shape of the element and must therefore be positioned on the thinner crossbar so as to be farther from the part to overmold than when the mold is positioned on a cross more thick.
- a cross comprises two slopes spaced a given space and forming a non-zero angle between them, the mold may come into intimate contact with one of the two slopes without reaching the bottom of this slope.
- the wall of the mold is thus remote from the other slope of the given space plus the length due to the inclination of the two slopes on the height of these slopes not covered by the mold (see FIGS. 7A and 7B).
- the mold can therefore not come into intimate contact with the second slope and the additional space provided between the wall of the mold and the second slope decreases the pressure losses occurring in the plastic material leaving the mold.
- the two slopes are parallel, the space between these two slopes is constant, and the wall of the mold comes into intimate contact with the two slopes, even when there are variations in thickness between the different sleepers (see Figures 8A and 8B). This characteristic makes it possible to maintain a satisfactory seal during overmoulding even in the case of variations in thickness;
- the cross member is a front end of a motor vehicle and preferably forms a beam of a front end of a motor vehicle.
- the mold is shaped to form on the cross member at least one amount substantially perpendicular to the cross member, preferably two spaced apart amounts and essentially parallel to each other.
- the two uprights can be connected to each other by another cross, called lower crossbar, parallel to the cross member forming the insert.
- the mold can also be shaped to form on the upright at least one side arm extending parallel to one end of the cross member along its longitudinal dimension, this arm can be used for fixing an optical or other accessories.
- a "molding cycle" comprises, for injection molding, the injection and compacting steps.
- the material does not escape the mold, which further saves manufacturing costs.
- maintenance costs of the workshop in which the parts are manufactured are saved;
- the receiving zone of the cross-member and the wall portion of the mold are shaped so that a flow of plastic material escaping from the mold solidifies when it is in the receiving zone.
- the solidification is due to the cooling of the material and the loss of speed thereof.
- the solidification of the plastic material completely closes the passage formed between the mold wall and the cross.
- the plastic forms a seal ensuring complete sealing of the mold. The seal saves even more material and, as a result, further reduces manufacturing costs.
- the invention also relates to a cross member of the assembly according to the invention, as well as a mold belonging to the assembly according to the invention.
- another object of the invention is a technical front end of a motor vehicle, comprising a cross member, forming in particular beam, and at least one amount overmolded on the cross member, substantially vertical extending downwardly when the front side technical is mounted on the motor vehicle and made of plastic, preferably a thermoplastic material such as polypropylene, the upright and the crossbar each having a connecting zone in which they are connected, the crossbar comprising, in the connection zone, at least one level difference with respect to a reference surface along the general outline of the beam.
- the unevenness is preferably covered with a thin layer of plastic material.
- the technical front is an overmolded part manufactured using an assembly as defined above comprising a cross member and a mold.
- the transom may include all the features of that described above.
- the technical front has two substantially vertical uprights spaced on the cross member and connected at their lower end by another cross, called lower cross, preferably integrally molded with the uprights.
- Each of the uprights is intended to support at least one functional element, such as the optical block, and the lower cross member forms a shock beam.
- the technical front face according to the invention allows to assemble outside the main assembly line many elements of the front block.
- the subject of the invention is also an assembly of a mold and a batch of two crosspieces, each of the crosspieces being according to the invention, and at least one wall portion of the mold, preferably each wall portion of the mold intended to be opposite a reception zone, being of substantially complementary shape to the corresponding reception zone of each of the two crosspieces, one of the two crosspieces comprising at least one portion having a shape different from a corresponding portion of the other of the two sleepers.
- the two sleepers can be overmolded in an identical shape, and this can be done with the aid of a single mold.
- This is for example advantageous in the case of a technical front for a motor vehicle platform in which the shape of the cross member, constituting a structural part of the vehicle, can change depending on the vehicle model and the desired mechanical properties the molded part can remain the same.
- each of the two sleepers has a spacing between the receiving areas of each of the two sleepers. This makes it possible to use the same mold, even in the case where the insert cross-member comprises a plurality of mold wall receiving zones.
- the two crosspieces of the batch have a difference in thickness
- the thickness of the cross-member is its dimension taken in the direction of molding.
- each of the two sleepers has several unevennesses each formed in one or other of its receiving zones and having slopes substantially constant and parallel to each other, at an angle of clearance.
- the mold can be in intimate contact with all the slopes of the receiving zone, despite the variation of the thickness of the cross-member and can therefore be positioned on the two crosspieces so as to form a part overmolding of constant thickness ensuring a seal during overmoulding, even if the two crosspieces have variations in thickness.
