Technical field
The present invention relates to a kind of Glass Run and manufacture method thereof.
Background technology
Usually, along week Glass Run being set in the self-propelled vehicle doorframe.Observe from its section, Glass Run comprises the main part of U-shaped cross-section, and this main part forms by basal part and from madial wall portion and lateral wall portion that basal part stretches out, and Glass Run also comprises and extends to interior sealing lip of main part in-to-in and outer seal lip.The sealing means of above-mentioned Glass Run is main part is contained in along in the installation portion (channel guide section) that week is provided with in the doorframe, and the circumference of door glass surfaces externally and internally to be clipped between interior sealing lip and the outer seal lip.
In addition, Glass Run comprises the roughly portion that extrudes of linearity that forms, and comprise molded section, molded section is arranged between the portion of extruding and at a predetermined angle the portion of extruding is connected, and, along the shape of doorframe, Glass Run forms (for example, referring to Japanese patent gazette JP 2006-8045A) by for example preceding vertical sidepiece, the vertical sidepiece of upper lateral part and back.
At that time, when Glass Run was made up of portion of extruding and molded section, the connection lead of extruding between portion and the molded section can be exposed, and this can cause the deterioration of presentation quality.In addition, the portion that extrudes may be different with the composition material of molded section, thereby, extrude portion and molded section color and gloss and have than big-difference on the surface.This species diversity of color and gloss also can cause the deterioration of presentation quality.In addition, the boundary between portion of extruding and molded section (connecting portion) locates to form easily step, and this can cause reducing sealing property.In addition, the local change when extruding the cross sectional shape of portion need carry out post-processing respectively to these parts.
In contrast, also propose Glass Run is shaped to inside structure body and outboard structure body separately, then with two structure integrators (for example, referring to U.S. Patent No. 5,396,733).
Adopting the technology of U.S. Patent No. 5,396,733, can avoid taking place following situation: the difference of color and gloss vertically appears along Glass Run, and, longitudinally form the N/R step.
Yet, in U.S. Patent No. 5,396, in the 733 described Glass Runs,, needing at least two cover or more large-scale molding apparatus because inside structure body and outboard structure body separate moulding, this causes cost to increase.In addition, not only need to assemble the operation of these two structures, but also worry to misplace between two structures, thereby, if two structures of assembling not accurately can cause the reduction of sealing property, the problems such as deterioration of installing condition on installation portion.
In addition, for the part that contacts with the door glass slides in the Glass Run, that is, the door glass slides face of the inside face of basal part and sealing lip in order to improve the sliding capability of a glass, it is desirable to sticking polyethylene (PE) band or applies antiseize paste to form sliding layer.
Yet, when forming sliding layer, need separate with the step of molding owing to form the step of sliding layer, this not only increases man-hour but also reduces manufacturing operation.In addition, for U.S. Patent No. 5,396, therefore 733 described Glass Runs if want to form sliding layer in the stage that outboard structure body and inside structure body separate, also can increase the man-hour of pasting or applying operation.
Summary of the invention
Consider that above-mentioned situation proposes the present invention, and, the objective of the invention is, a kind of Glass Run and manufacture method thereof are provided, presentation quality can be improved, and manufacturing operation can be improved, can also reduce manufacturing cost.
Below, explanation is suitable for achieving the above object and every scheme of other purposes item by item.In addition, as required, also add distinctive operation of corresponding scheme and effect.
In a first aspect of the present invention, a kind of Glass Run is provided, comprising:
Main part is installed on the installation portion that is provided with along week in the door frame for vehicle, and has roughly U-shaped cross section, and main part comprises basal part and from madial wall portion and lateral wall portion that basal part stretches out; And
Interior sealing lip and outer seal lip reach main part inside from the roughly front end of madial wall portion and lateral wall portion,
Wherein: whole longitudinal region is one-body molded through molding, be provided with a door glass rising wood cooresponding upper lateral part, with door glass exterior region cooresponding before vertical sidepiece and with the vertical sidepiece in the cooresponding back of door glass hinder marginal part,
Interval in during molding between sealing lip and the outer seal lip is set at more than or equal to 1.5mm and smaller or equal to 3.0mm, and
Main part and interior sealing lip and outer seal lip are made by olefin hydrocarbons thermoplasticity elastic body.
According to a first aspect of the invention, the whole longitudinal region of Glass Run is through molded.So, compare with the situation that molded item is formed by extruding part with for example Glass Run, can avoid externally exposing the connection lead of extruding between part and the molded item.In addition, can avoid occurring the difference of color and gloss along vertical (circumferentially) part of Glass Run.As a result, can realize the raising of presentation quality.In addition, can avoid vertically forming the N/R step, thereby can realize the raising of sealing property along Glass Run.
In addition, because molded item is extruded the part height at ratio aspect the degree of freedom of product design, even for example Glass Run can be easily by molded when specific part has different cross section shape (for example, when longitudinally the local length that lug boss is set or changes sealing lip).So, can avoid because of forming the independent operation (post-processing) that the different cross section shape needs at specific part, thereby, can realize the raising of capacity rating.
In addition, compare by the situation of assembling a plurality of molded items and forming,, can improve manufacturing operation owing to do not need assembly manipulation with Glass Run for example, and, owing to only need a cover molding apparatus get final product all right cost-cutting.In addition, can avoid following situation: dislocation takes place or separates in a plurality of molded items of forming Glass Run, causes the reduction of sealing property, the deterioration, the reduction of fitting operation etc. of installing condition on installation portion.
As described in a first aspect of the present invention, with being set between interior sealing lip and the outer seal lip more than or equal to 1.5mm, can guarantee the intensity that holding plate keeps module (core), with forming body portion, interior sealing lip and outer seal lip inner peripheral surface separately.In addition, with being set between interior sealing lip and the outer seal lip, can guarantee thickness is typically about the sealing property of surfaces externally and internally in the door glass periphery of 4.0mm to 5.0mm smaller or equal to 3.0mm.
When main part and sealing lip by elastomeric material such as EPDM rubber (ethylene propylene diene rubber) when making, EPDM etc. have higher relatively viscosity, if this material is filled up in the every nook and cranny in mold cavity, just need provide very high injection pressure, perhaps, need to increase the quantity of the running channel that is used to inject.During a kind of structure, EPDM etc. can invade the docking section of a plurality of modules of formation die cavity before adopting, and this can cause burr.On the other hand, adopt a kind of structure the in back can cause the complicated of mould structure.In contrast, according to the present invention, because main part and sealing lip are made by olefin hydrocarbons thermoplasticity elastic body (TPO), the viscosity of TPO is lower than the viscosity of EPDM etc., can prevent burr, also can avoid the complicated of mould structure, thereby suppress the increase of manufacturing cost.In addition, the result as form main part and sealing lip with TPO no longer needs vulcanisation step, thereby, in this, can also realize the raising of capacity rating.
In upper lateral part, the salient that raises up from basal part can locally be set.
Because in above-mentioned feature, even when salient from the basal part projection is set, salient can be when molding and basal part one-body molded.So, can avoid following situation:, and therefore cause the reduction of manufacturing operation owing to the setting of salient needs post-processing.In addition, the example of salient comprises: the lug boss (damper element) that is used to cushion the impact when closing glass; And, and be formed on the lug boss that hole portion in the installation portion or recess hook, be used to control Glass Run skew longitudinally.

Below, be described more specifically the manufacture method of Glass Run 1.According to the Glass Run 1 of present embodiment, for example, utilize molding apparatus shown in Figure 5 40 moldings to form.More specifically, molding apparatus 40 comprises first module 41, second module 42, the 3rd module 43, the 4th module 44, the 5th module 45, the 6th module 46 and the 7th module 47.In addition, the 3rd module 43 is made up of core 43a and holding plate 43b, core 43a forming body portion 11, outer seal lip 12 and interior sealing lip 13 inner peripheral surface separately, and holding plate 43b then keeps core 43a.Form and the corresponding forming surface of Glass Run 1 profile respectively on these modules 41 to 47, the die cavity 49 that these forming surface form is used for formed glass chute 1.
With the vertical sidepiece 4 cooresponding part bendings of preceding vertical sidepiece 3 and back, as mentioned above, thereby the vertical sidepiece 4 of preceding vertical sidepiece 3 and back tilts to vehicle interior side in the die cavity 49.In addition, in the present embodiment, the thickness setting of the holding plate 43b of the 3rd module 43 is 1.5mm to 3.0mm.
Then, via the cast gate 51 and the running channel 52 that are formed in the 7th module 47, the TPV that will be in plastic state by injection device 50 injects die cavity 49 and fills up.After curing was finished, die sinking was also taken out the Glass Run 1 of moulding from molding apparatus 40.Thereby the whole longitudinal region of the aforesaid Glass Run 1 of moulding comprises the cross sectional shape with main part 11 and sealing lip 12 and 13, and, be provided with the vertical sidepiece 4 in upper lateral part 2, preceding vertical sidepiece 3 and back.Afterwards, by basal part 14 and sealing lip 12 and 13 are applied surface treatment, make Glass Run 1.
As described in detail above, in the present embodiment, the moulding of the whole longitudinal region of Glass Run 1 by molding.So, compare with the situation that molded item is formed by extruding part with for example Glass Run 1, can avoid extruding the situation that the connection lead between part and the molded item is exposed on the external.In addition, can avoid occurring the difference of color and gloss along vertical (circumferentially) part of Glass Run 1.As a result, can realize the raising of presentation quality.In addition, can avoid along the unnecessary step of vertical formation of Glass Run 1, thereby, can realize the raising of sealing property.
In addition since molded item to extrude part at ratio aspect the product design degree of freedom higher, for example, even Glass Run is when privileged site has different cross sectional shapes, also easily by the molding methods moulding.In the present embodiment, for upper lateral part 2 glass guide 31 is set although proposed, but guiding piece 31 when molding and other parts be shaped simultaneously, need not carry out independent operation, promptly, for example need not lateral wall portion of local excision 15 after Glass Run 1 molding, perhaps independent formed glass guiding piece.In addition, in the present embodiment, the shape of molding lip 17 and inner mold lip 18 outside although the part (bottom of back vertical sidepiece 4 and preceding vertical sidepiece 3) of Glass Run 1 below stringcourse is shaped to and omits, but this in moulding process with the moulding simultaneously of other parts, and need not carry out independent operation, that is, for example need not to cut out outer molding lip 17 and inner mold lip 18.So, can avoid carrying out independent operation (post-processing) because of specific part need form the different cross section shape, thereby, can increase productivity.
In addition, for example make Glass Run 1, by comparison,, realized the raising of manufacturing operation because the present invention need not assembly manipulation by assembling a plurality of molded items, and, owing to only need a cover molding apparatus, can cost-cutting.In addition, can prevent following situation: promptly, dislocation takes place and separates in a plurality of molded items of forming Glass Run, causes the reduction of sealing property, the deterioration of installing condition and the reduction of fitting operation performance on installation portion.
In addition, when molding, the interval W1 between interior sealing lip 13 and the outer seal lip 12 is set at more than or equal to 1.5mm and smaller or equal to 3.0mm.Being set to more than or equal to 1.5mm between interior sealing lip 13 and the outer seal lip 12 can guarantee forming body portion 11, outer seal lip 12 and interior sealing lip 13 intensity of the 3rd module 43 (holding plate 43b) of inside face separately.In addition, being set between interior sealing lip 13 and the outer seal lip 12 smaller or equal to 3.0mm, can save the operation that follow-up pressure narrows down the interval between sealing lip 12 and 13, thereby, can guarantee thickness is approximately the sealing property of the door glass DG surfaces externally and internally circumference of 4.0mm to 5.0mm.
In addition, Glass Run 1 (main part 11 and sealing lip 12 and 13) is made by TPV.For example, when Glass Run 1 was made such as EPDM by elastomeric material, EPDM etc. had higher relatively viscosity, like this, if want in the die cavity 49 of molding apparatus 40 each corner to fill up this material, need very high injection pressure, perhaps need to increase the quantity of the running channel that is used to inject.During a kind of structure, EPDM etc. can invade the docking section of a plurality of modules of formation die cavity 49 before adopting, and this can cause burr.On the other hand, adopt a kind of structure in back then can cause the complicated of mould structure.In contrast, according to the embodiment of the present invention,, can prevent burr, also can avoid the complicated of mould structure, thereby avoid increasing manufacturing cost because Glass Run 1 is made by the TPV that viscosity is lower than EPDM etc.In addition, adopt TPV to form Glass Run 1, no longer need vulcanisation step, thereby, can increase productivity.
In addition, in moulding process, the vertical sidepiece 4 in upper lateral part 2, preceding vertical sidepiece 3 and back forms consistent with the curvature of channel guide section DC.So than such situation, it is also crooked to be installed on the channel guide section DC that the linearity Glass Run is extended along channel guide section DC, embodiments of the present invention can realize stability, the raising presentation quality of installing condition and improve sealing property.
In addition, usually, the variation of molded item cross sectional shape (manufacturing errors) is very little, and only is made up of molded item according to the Glass Run 1 (main body of Glass Run 1) of present embodiment, therefore, can realize the raising of quality.In addition, compare when part is formed with molded item by extruding, can realize the raising of work efficiency, the simplification of equipment etc. with Glass Run 1, and, can increase productivity, cost-cutting etc.
In addition, be not limited to the description of contents of above-mentioned embodiment, the present invention also can be realized by other modes described below.Certainly, the present invention also can be implemented by other modes hereinafter do not mentioned and improved form.

Below, be described more specifically the manufacture method of Glass Run 101.According to the Glass Run 101 of present embodiment, for example, utilize molding apparatus shown in Figure 11 140 moulding.More specifically, molding apparatus 140 comprises first module 141, second module 142, the 3rd module 143, the 4th module 144, the 5th module 145, the 6th module 146 and the 7th module 147.In addition, the 3rd module 143 is made up of core 143a and holding plate 143b, core 143a forming body portion 111, outer seal lip 112 and interior sealing lip 113 inner peripheral surface separately, and holding plate 143b then keeps core 143a.On these modules 141 to 147, form and the cooresponding forming surface of Glass Run 101 profiles respectively, and the die cavity 149 that these forming surface form is used for formed glass chute 101.In addition, in the present embodiment, set like this, make that the thickness of holding plate 143b of the 3rd module 143 is 1.5mm to 3.0mm.
Then, via the cast gate 151 and the running channel 152 that are formed in the 7th module 147, the TPV that will be in plastic state by injection device 150 injects die cavity 149 and fills up.After curing was finished, die sinking was also taken out the Glass Run 101 of moulding from molding apparatus 140.Thereby, the whole longitudinal region of continuously shaped Glass Run 101, it has and comprises main part 111, sealing lip 112 and 113 and the cross sectional shape of junction surface 124 and 134, and is provided with the vertical sidepiece 104 in upper lateral part 102, preceding vertical sidepiece 103 and back.Afterwards, by basal part 114 and sealing lip 112 and 113 are applied surface treatment, make Glass Run 101.
In addition, last functor 121 and the predetermined independent moulding of molding apparatus of vertical functor 131 usefulness.Then, be mounted to upper lateral part 102 and vertical functor 131 is mounted to the vertical sidepiece 104 of preceding vertical sidepiece 103 and back by going up functor 121, formation has the Glass Run 101 of cross sectional shape as mentioned above.Afterwards, sealing lip 112 and 113 is applied surface treatment, thereby make Glass Run 101.
As described in detail above, in the present embodiment, the moulding of the whole longitudinal region of Glass Run 101 by molding.So, than common process, for example being connected to form Glass Run 101 vertically will extruding part and molded item, the connection lead that can avoid extruding between part and the molded item is exposed on the external.In addition, can avoid occurring the difference of color and gloss along vertical (circumferentially) part of Glass Run 101.As a result, can improve presentation quality.In addition, can avoid along the unnecessary step of vertical formation of Glass Run 101, thereby, sealing property can be improved.
In addition,, for example form Glass Run 101,, improved manufacturing operation owing to do not need assembly manipulation by a plurality of molded items of assembling than common process, and, owing to only need a cover molding apparatus, can also cost-cutting.In addition, can prevent following situation: promptly, a plurality of molded items of forming Glass Run dislocation occurs and separate, and cause the reduction of sealing property, the deterioration of installing condition and the reduction of fitting operation on installation portion.
In addition, according to present embodiment,, and be that the vertical sidepiece 104 of preceding vertical sidepiece 103 and back is provided with vertical functor 131 for upper lateral part 102 is provided with functor 121.
In addition, more specifically, when closing a glass DG, function portion 122 connects with the rising wood of door glass DG in the last functor 121, and the major part of function portion 122 is formed by expanded material.Take this to absorb the impact due to the glass DG bump, the result can reduce the impact noise when closing a glass DG.
In addition, when overhead door glass DG, the forward and backward vertical edge portion of the basal part 135 of function portion 132 and door glass DG connects in the vertical functor 131, and this basal part 135 is made by polyethylene, and it is harder than the basal part 114 that TPV makes.So, can improve the sliding of glass DG and door glass DG resistance to abrasion corresponding to moving contact.
In addition, in the function portion 132 of vertical functor 131, be provided with secondary lip 138, make secondary lip 138 can contact the surface (back side) that is positioned at a glass slides contact surface opposite side in the interior sealing lip 113.So when door glass DG tends to when vehicle interior side is offset, a door glass DG is supported in interior sealing lip 113 and 138 bendings of secondary lip simultaneously, with combined action door glass DG is pushed back.Thereby, can suppress a glass hits noise.In addition, be clipped in the middle with door glass DG by secondary lip 138 because interior sealing lip 113 is subjected to supporting simultaneously, can prevent following situation: interior sealing lip 113 is in the vehicle-width direction swing, thereby interior sealing lip 113 separates with door glass DG.In view of the above, can improve sealing property and sound insulation property.
In addition since molded item to extrude part at ratio aspect the product design degree of freedom higher, for example, even Glass Run when privileged site has the different cross section shape, also carries out moulding by molding easily.In the present embodiment, although propose along Glass Run 101 vertically by joint 124 and 134 are set every preset space length, but these junction surfaces are when molding and the moulding simultaneously of other parts, and need not carry out independent operation (such as local excision's basal part 114 after Glass Run 101 moldings).In addition, in the present embodiment, the shape of molding lip 117 and inner mold lip 118 outside although the part (bottom of back vertical sidepiece 104 and preceding vertical sidepiece 103) of Glass Run 101 below stringcourse is shaped to and omits, but this is shaped simultaneously with other parts in moulding process, need not carry out independent operation (such as outer molding lip 117 of excision and inner mold lip 118).So, the situation that can avoid when specific part has the different cross section shape, need operating separately (post-processing), thereby, can increase productivity.
In addition, when molding, the interval W1 between interior sealing lip 113 and the outer seal lip 112 is set at more than or equal to 1.5mm and smaller or equal to 3.0mm.Being set to more than or equal to 1.5mm between interior sealing lip 113 and the outer seal lip 112 can guarantee the intensity of the 3rd module 143 (holding plate 143b) of molded body portion 111, outer seal lip 112 and interior sealing lip 113 inside face separately.In addition, being set between sealing lip 113 and the outer seal lip 112 smaller or equal to 3.0mm, can save the operation that forces the interval between sealing lip 112 and 113 to narrow down in the subsequent operation, thereby, can guarantee thickness is approximately the sealing property of the door glass DG surfaces externally and internally circumference of 4.0mm to 5.0mm.
In addition, main part 111 and sealing lip 112 and 113 are made by TPV.For example, when main part 111 and sealing lip 112 and 113 are made such as EPDM by elastomeric material, EPDM etc. have higher relatively viscosity, like this, fill up this material if want in the die cavity 149 of molding apparatus 140 each corner, need very high injection pressure, perhaps need to increase the quantity of the running channel that is used to inject.During a kind of structure, EPDM etc. can invade the docking section of a plurality of modules of formation die cavity 149 before adopting, and this can cause burr.On the other hand, adopt a kind of structure in back then can cause the complicated of mould structure.In contrast,,, can prevent burr, also can avoid mould structure complicated, thereby suppress the increase of manufacturing cost because main part 111 and sealing lip 112 and 113 are made by low TPV such as viscosity ratio EPDM according to present embodiment.In addition, the result as form main part 111 and sealing lip 112 and 113 with TPV no longer needs vulcanisation step, thereby, can realize the raising of capacity rating.
In addition, need not be confined to the description of above-mentioned embodiment, the present invention also can be implemented as for example following mode.Nature also can constitute hereinafter not illustrative other application and change.
(a) as shown in figure 12, the function portion 122 of last functor 121 can be shaped as hollow form.Thereby when closing a glass DG, the inside of the basal part 114 that connects with door glass DG rising wood forms hollow part 122a.In this case,, can absorb an impact that causes with door glass DG butt by means of the repulsive force of hollow part 122a, and the impact noise can suppress to close a glass DG more reliably the time.In addition,, form independent parts, can not cause the difficulty of molding processing by going up functor 121 although be difficult to form hollow form in the whole cross section of mold glass chute 101.
Equally, can omit functor 121 and joint 124.In addition, the buffering salient can be set, its basal part 114 from upper lateral part 102 is raised up, and the impact of buffering when closing a glass DG.In addition, the offset-limited projection can be set, its basal part 114 from upper lateral part 102 is raised up, and, be installed at Glass Run 101 under the state of channel guide section DC, by offset-limited projection and the hole portion or the recess that are formed among the channel guide section DC are hooked, control Glass Run 101 skew longitudinally.In addition, upper lateral part 102 can be provided with glass guide, glass guide from the border between lateral wall portion 115 and the outer seal lip 112 to lower convexity, and, as the door glass DG that rises during to the vehicle outside dislocation, glass guide is directed to the rising wood of door glass DG in the main part 111.Therefore, even buffering salient, offset-limited projection and glass guide etc. are set, these parts can be when molding and other parts one-body molded.So, can avoid following situation: need post-processing owing to buffering salient, offset-limited projection, glass guide etc. are set, and therefore cause reducing the manufacturing operation performance.In addition, can be in the moulding process of Glass Run 101 insert moulding offset-limited projection.
(b) in the present embodiment, although the secondary lip 138 that is arranged in the vertical functor 131 forms, extend from basad 114 side of leading section of extension 137 (stretching out) from base portion 135, but the present invention is not confined to this structure especially, can contact with the surface (back side) that interior sealing lip 113 is positioned at a glass slides contact surface opposite side as long as secondary lip 138 is configured as.For example, as shown in figure 13, secondary lip 138 can be positioned at the leading section back side of the inside sealing lip 113 in end of madial wall portion 116 sides and extend from the base portion 135 of vertical functor 131.
(c) the lip shape portion 136 according to the vertical functor 131 of above-mentioned embodiment can omit.In addition, shown in Figure 14 A and Figure 14 B, before vertical functor 131 was installed, the protrusion direction that the base portion 135 of vertical functor 131 can be formed to junction surface 133 tilted, in this way from the connecting portion or near the horizontal expansion it at base portion 135 and junction surface.In this case, under the installing condition of vertical functor 131, base portion 135 can constitute pressure with the inside face of basal part 114 and contact.Thereby, can prevent that base portion 135 from floating from basal part 114, and can prevent owing to float the sliding deterioration that causes a glass DG.
In addition, also can omit vertical functor 131 and joint 134.In this case,, for example, can wait to form sliding layer by sticking polyethylene (PE) band, perhaps can form coating (for example, polyurethane coating) for the inside face of the basal part 114 of vertical sidepiece 103,104.
(d) in the above-described embodiment, although main part 111 and sealing lip 112 and 113 are made by TPV, the present invention is not confined to this structure especially, and for example, these parts also can be made by non-crosslinked olefin hydrocarbons thermoplasticity elastic body (TPO).
In addition, make by EPDM, also can make such as TPO by other materials although go up functor 121.Yet, it is desirable to, the function portion 122 of last functor 121 has absorption and causes the function of impacting because of door glass DG butt.In addition, although the junction surface 133 of vertical functor 131 and lip shape portion 136 are made by TPV, and base portion 135 is made by polyethylene, but junction surface 133 and lip shape portion 136 also can be made by non-crosslinked olefin hydrocarbons thermoplasticity elastic body and EPDM, and base portion 135 then can be made by polypropylene and other materials.Yet, it is desirable to, the base portion 135 of vertical functor 131 is made by the material harder than the material of basal part 114.In addition, form junction surface 123 and 133, can improve the operating characteristic that functor 121 and 131 is installed on basal part 114 (joint 124 and 134) by the material (for example, the material harder) that uses hardness to reach to a certain degree than EPDM.
In addition, in the present embodiment,,, also can pass through molded whole longitudinal region, and functor 121 and vertical functor 131 can be set about the Glass Run of tail gate etc. although described the Glass Run 101 of driver door especially in detail.In addition, the present invention can also be applied to cross sectional shape for example not with the Glass Run of molding lip 117 and 118.
In addition, in Figure 11, although the holding plate 143b of the 3rd module 143 form thickness be slightly smaller than between the forming surface of sealing lip 113 in the forming surface of moulding outer seal lip 112 and the moulding the interval (just, interval during molding between outer seal lip 112 and the interior sealing lip 113), but holding plate 143b also can form thickness the time with molding the interval between outer seal lip 112 and the interior sealing lip 113 identical.
(e) in addition, when molding, the vertical sidepiece 104 of preceding at least vertical sidepiece 103 and back can form and the corresponding to case of bending of the curvature of channel guide section DC.More specifically, for car door 61, in design, car door 61 can be shaped to case of bending from the top that stringcourse begins, and tilting to vehicle interior side, therefore, not only door glass DG but also channel guide section DC are configured as case of bending.Be shaped to and the corresponding to case of bending of the curvature of channel guide section DC by the vertical sidepiece 104 of preceding vertical sidepiece 103 and back Glass Run 101, than such situation, it is also crooked to be installed on the channel guide section that the linearity Glass Run is extended along channel guide section DC, and the present invention can realize stability, the raising presentation quality of installing condition and improve sealing property.

Outer seal lip 212 and interior sealing lip 213 according to present embodiment are not straight-line extensions, but slightly crooked when extending, to bloat slightly to door glass DG under the state that is installed on channel guide section DC.Thereby, realize the raising of sealing property.In addition, the boundary between basal part 214 and lateral wall portion 215, and the boundary between basal part 214 and madial wall portion 216 forms to the recessed notch 219 of main part 211 peripheries.Owing to be provided with above-mentioned notch 219, when Glass Run 201 is installed on channel guide section DC, two side wall portions 215 and 216 are all shunk, thereby, can improve the fitting operation performance.
In addition, as shown in figure 16, in the present embodiment, under the state before Glass Run 201 is installed on channel guide section DC, the interval W1 between the leading section of the leading section of outer seal lip 212 and interior sealing lip 213 is set in the scope of 1.5mm to 3.0mm.On the other hand, the thickness of door glass DG is about 4.0mm to 5.0mm.So, when Glass Run 201 being installed on channel guide section DC (or the DS of frame portion) (fitting in together),, and need not to force the interval between outer seal lip 212 and the interior sealing lip 213 to narrow down by the circumference of pair of seal lips 212 and 213 energy positiver sealing door glass DG.
In addition, upper lateral part 202 and preceding vertical sidepiece 203 also comprise main part 211 and pair of seal lips 212 and 213.Yet, be arranged in the following door-plate 63 of stringcourse in the Glass Run 201 and the part that the is not exposed bottom of the vertical sidepiece 204 of preceding vertical sidepiece 203 and back (in this example for) in, omit outer molding lip 217 and inner mold lip 218, and, the size of the DS of frame portion that this part is installed is reduced.In addition, outer seal lip 212 forms than interior sealing lip 213 short (little).Thereby DG pushes vehicle outside to door glass, thereby can obtain flush.In the present embodiment, the whole longitudinal region of Glass Run 201 is one-body molded through molding, has the cross sectional shape that comprises main part 211 and interior outer seal lip 212 and 213, and is provided with the vertical sidepiece 204 in upper lateral part 202, preceding vertical sidepiece 203 and back.
In addition, in the present embodiment, sliding layer 221 and interior sliding layer 222 outside on the door glass slides face of outer seal lip 212 and interior sealing lip 213, forming, and on the inside face of basal part 214, form base portion side sliding layer 223.Thereby, improve the sliding of door glass DG at each several part.In addition, although can describe in detail hereinafter, each sliding layer 221,222 of brief description and 223 is made by polyethylene (PE) sheet material here, and polyethylene (PE) sheet material is imbedded to be exposed on the surface as sliding part.In addition, on the door glass slides face of outer seal lip 212 and interior sealing lip 213, the part that is formed with sliding layer 221,222 is concordant with the part that does not comprise sliding layer 221,222, does not have step therebetween.In addition, (from the notch 219 that is positioned at vehicle outside to the notch 219 that is positioned at vehicle interior side) forms base portion side sliding layer 214 along the whole zone of vehicle-width direction across basal part 214.
Then, molding apparatus shown in Figure 17 240 is described, its by way of example explanation is used for the molding apparatus of the Glass Run 201 of moulding present embodiment.In addition, Figure 17 is illustrated in and puts into PE thin slice 231,232 and 233 in the die cavity 249 to form sliding layer 221,222 and 223, afterwards, is in the section of the molding apparatus 240 under the matched moulds state.
As shown in figure 17, molding apparatus 240 comprises first module 241, second module 242, the 3rd module 243, the 4th module 244, the 5th module 245, the 6th module 246 and the 7th module 247.On these modules 241 to 247, form respectively and the cooresponding forming surface of the profile of Glass Run 201, and the die cavity 249 that these forming surface form is used for formed glass chute 201.
In addition, the 3rd module 243 is made up of core 243a and holding plate 243b, core 243a forming body portion 211, outer seal lip 212 and interior sealing lip 213 each corresponding inner peripheral surface, and holding plate 243b then is used to keep core 243a.In addition, in the 3rd module 243 (core 243a), the office, both sides on the forming surface of moulding basal part 214 inside faces is provided with a pair of moulding salient 243c towards die cavity 249 internal projection.By means of moulding salient 243c, the boundary between basal part 214 and lateral wall portion 215, and, the boundary between basal part 214 and madial wall portion 216, moulding notch 219.In addition, in the present embodiment, the thickness setting of the holding plate 243a of the 3rd module 243 is 1.5mm to 3.0mm.
In addition, in second module 242 in the forming surface of 212 glass slides faces of moulding outer seal lip, form first suction socket 254, in the 3rd module 243 in the forming surface of moulding basal part 214 inside faces, form second suction socket 255, and, in the 4th module 244, in the moulding in the forming surface of 213 glass slides faces of sealing lip, form the 3rd suction socket 256.In the present embodiment, form the aspirator 257 that is arranged side by side with molding apparatus 240, so that can be via the air in suction socket 254,255 and the 256 suction die cavities 249.
Below, the manufacture method of Glass Run 201 is described.At first, under the die opening state of molding apparatus 240, in second module 242, place PE thin slice 231 on the forming surface of 212 glass slides faces of moulding outer seal lip, in the 4th module 244, place PE thin slice 232 in the moulding on the forming surface of 213 glass slides faces of sealing lip, and, in the 3rd module 243, place PE thin slice 233 on the forming surface of moulding basal part 214 inside faces.Especially, with basal part 214 inside face corresponded manners PE thin slice 233 to be set, the transverse width of PE thin slice 233 forms the distance that is substantially equal between a pair of moulding salient 243c that is arranged in the 3rd module 243 (core 243a).Thereby in the time of on being placed on forming surface, PE thin slice 233 is arranged between a pair of moulding salient 243c, and makes two sidepieces of PE thin slice 233 and moulding salient 243c butt respectively.In other words, PE thin slice 233 is accurately located.
In addition, when being placed on PE thin slice 231,232 and 233 on each forming surface, aspirate via 254,256 and 255 pairs of PE thin slices 231,232 and 233 of suction socket by aspirator 257.Thereby, make PE thin slice 231,232 and 233 close fit in cooresponding each forming surface, and keep this state.
Then, remain under the state that is sucked device 257 suction at PE thin slice 231,232 and 233 and to carry out matched moulds, afterwards, via the cast gate 251 and the running channel 252 that are formed in the 7th module 247, the TPV that will be in plastic state by injection device 250 injects die cavity 249 and fills up.The Glass Run 201 of moulding is taken out in die sinking after curing is finished from molding apparatus 240.Thereby, obtain the Glass Run 201 whole longitudinal regions of one mode as mentioned above, it has the cross sectional shape that comprises main part 211, sealing lip 212 and 213, sliding layer 221,222 and 223 etc., and is provided with the vertical sidepiece 204 in upper lateral part 202, preceding vertical sidepiece 203 and back.
As described in detail above, in the present embodiment, the moulding of the whole longitudinal region of Glass Run 201 by molding.So, be different from routine techniques, for example longitudinally connect a plurality of shaped objecies of extruding part that comprise to form Glass Run, embodiment of the present invention can avoid the connection lead of adjacent shaped object to be exposed on the external.In addition, can avoid occurring the difference of color and gloss along vertical (circumferentially) part of Glass Run 201.As a result, can improve presentation quality.In addition, can avoid along the unnecessary step of vertical formation of Glass Run 201, thereby, sealing property can be improved.
In addition, because molded item is extruded the part height at ratio aspect the product design degree of freedom, for example,, also carry out moulding by molding easily even Glass Run has the different cross section shape at privileged site.In the present embodiment, the shape of molding lip 217 and inner mold lip 218 outside although the part (bottom of back vertical sidepiece 204 and preceding vertical sidepiece 203) of Glass Run 201 below stringcourse is configured as and omits, but this is shaped simultaneously with other parts in moulding process, and need not carry out independent operation (such as outer molding lip 217 of excision and inner mold lip 218).So, can avoid because of specific part has the situation that the different cross section shape need be operated (post-processing) separately, thereby, can increase productivity.
In addition, than routine techniques, for example form Glass Run 201 by a plurality of molded items of assembling, owing to do not need assembly manipulation, embodiments of the present invention can improve the manufacturing operation performance, and, owing to only need a cover molding apparatus, can also cost-cutting.In addition, can prevent following situation: a plurality of molded items of forming Glass Run dislocation occurs and separate, and cause the reduction of sealing property, the deterioration of installing condition and the reduction of fitting operation on installation portion.
In addition, the thickness setting of the holding plate 243b of the 3rd module 243 is more than or equal to 1.5mm and smaller or equal to 3.0mm.The thickness of holding plate 243b is set to more than or equal to 1.5mm, can guarantee the intensity of the 3rd module 243 (holding plate 243b).In addition, the thickness setting of holding plate 243b is smaller or equal to 3.0mm, and the interval W1 when allowing molding between interior sealing lip 213 and the outer seal lip 212 is set to smaller or equal to 3.0mm.This can save the follow-up operation that forces the interval between sealing lip 112 and 113 to narrow down, thereby, can guarantee thickness is approximately the sealing property that the door glass DG surfaces externally and internally circumference of 4.0mm to 5.0mm provides.
In addition, main part 211 and sealing lip 212 and 213 are made by TPV.For example, when main part 211 and sealing lip 212 and 213 are made such as EPDM by elastomeric material, EPDM etc. have higher relatively viscosity, like this, fill up this material if want in the die cavity 249 of molding apparatus 240 each corner, need very high injection pressure, perhaps need to increase the quantity of the running channel that is used to inject.During a kind of structure, EPDM etc. can invade the docking section of a plurality of modules of formation die cavity 249 before adopting, and this can cause burr.On the other hand, adopt a kind of structure in back then can cause the complicated of mould structure.In contrast,,, can prevent burr, also can avoid the complicated of mould structure, thereby avoid the increase of manufacturing cost because main part 211 and sealing lip 212 and 213 are made by low TPV such as viscosity ratio EPDM according to present embodiment.In addition, the result as form main part 211 and sealing lip 212 and 213 with TPV no longer needs vulcanisation step, thereby, can increase productivity.
In addition, according to present embodiment, when mold glass chute 201, sliding layer 221,222 and 223 is shaped simultaneously.In other words, by insert moulding PE thin slice 231,232 and 233 when the molding, obtain to be formed with the Glass Run 201 of sliding layer 221,222 and 223.So, can omit following operation:, give the door glass slides face of sealing lip 212 and 213 and the inside face of basal part 214 such as after molding, paste band or apply antiseize paste, be used to form sliding layer 221,222 and 223, thereby, can realize the raising of manufacturing operation.
In addition, have compatibility with the PE thin slice 231,232 and 233 that forms sliding layer 221,222 and 223 owing to form the TPV of Glass Run 201, so, even do not use adhesives etc. separately, these parts are combined securely.
In addition, in the moulding process of Glass Run 201, PE thin slice 231,232 and 233 is placed in the die cavity 249, to form sliding layer 221,222 and 223, simultaneously according to present embodiment, via suction socket 254,256 and 255, the PE thin slice 231,232 and 233 that is placed in the die cavity 249 with 257 pairs of aspirators aspirates.Thereby, make PE thin slice 231,232 and 233 be in the state of close fit in cooresponding each forming surface, and the dislocation of control PE thin slice 231,232 and 233 and floating.And, in this state, will be in the TPV injection die cavity 249 of plastic state as formed material.So, can avoid following situation: when TPV is injected die cavity 249 and fills, PE thin slice 231,232 and 233 misplaces, perhaps, TPV clamp-on PE thin slice 231,232 and 233 and cooresponding each forming surface between, make PE thin slice 231,232 and 233 can not be exposed at the surface of Glass Run 201.In view of the above, make PE thin slice 231,232 and 233 go out reliably to be exposed on the surface in desired location, thereby, sliding layer 221,222 and 223 can be formed more accurately.
In addition, PE thin slice 233 about the setting of basal part 214 inside face corresponded manners, in the time of on PE thin slice 233 being positioned over the forming surface that forms die cavity 249, it is arranged as between a pair of moulding salient 243c that is arranged in the 3rd module 243 (core 243a), and two sidepieces that make PE thin slice 233 respectively with moulding salient 243c butt.When not only allowing PE thin slice 233 to be placed on the forming surface, this accurately locatees, and, when TPV charges into die cavity 249, can also prevent 233 dislocation of PE thin slice more reliably.
In addition, for example, if in order on the door glass slides face of outer seal lip 212 that forms case of bending and interior sealing lip 213, to form sliding layer, if after molding, paste PE thin slice 231 and 232, operate in this case can be relatively difficulty, cause the reduction, quality deterioration of operability etc.To this, according to present embodiment,, can in molding, form sliding layer 221 and 222, and make it be in the exact location for the door glass slides face of outer seal lip 212 and interior sealing lip 213, therefore, can eliminate above-mentioned rough sledding.In addition, can avoid following situation: on the door glass slides face of sealing lip 212,213, the boundary between sliding layer 221,222 and the general part made by TPV forms step.
In addition, for example Glass Run is separately become inside and outside two molded items at basal part, and, in this mode, need on two molded items, to form and the cooresponding sliding layer of basal part inside face (base portion side sliding layer) separately by two molded item assemblings are formed Glass Run.In this case, in the moulding process of two molded items, need to form the operation of base portion side sliding layer respectively, and this can cause reducing the manufacturing operation performance, make mould structure complicated etc. unfavorable.In addition, each molding apparatus for each molded item of moulding, need set up an organization respectively (such as suction socket is set) is used for preventing respectively that the PE thin slice of placing (being used to form the base portion side sliding layer) from misplacing.At this on the one hand, according to present embodiment, by the whole longitudinal region of the one-body molded Glass Run 201 of molding, Glass Run 201 has the cross sectional shape that comprises main part 211 and outer seal lip 212 and interior sealing lip 213.More specifically, the cooresponding base portion side sliding layer 223 of inside face of formation and basal part in single molded item.In view of the above, because single job can form base portion side sliding layer 223, can avoid above-mentioned unfavorable.
In addition, be not limited to the description of above-mentioned embodiment, the present invention also can be implemented by for example following mode.Certainly, also can carry out hereinafter not illustrative other application and improvement to the present invention.
(a) although use in the above-described embodiment aspirator 257 with PE thin slice 231,232 and 233 (sliding part) close fit in forming surface and keep the close fit state, but the present invention is not confined to this structure especially, as long as adopt the structure that can prevent the sliding part dislocation when die cavity 249 is filled in that TPV is injected.For example, utilize static also can prevent the sliding part dislocation.In this case, because confining force can be uniformly applied to the whole surface of sliding part, can prevent that sliding part part on the forming surface from floating.
Selectively, can control part be set for module 242,244 and 243, this control part hooks the end of PE thin slice 231,232 and 233.In this case, even without aspirator etc. is set, also can controls the skew of PE thin slice 231,232 and 233 and float by means of control part.As a result, can prevent the dislocation of sliding part, be suppressed to the increase of this aspect etc. simultaneously.In addition, can with control part with as above-mentioned embodiment in aspirator be used in combination, and, in this case, can prevent more reliably that the sliding part end from floating.In addition, control part can be along vertical local setting of die cavity 249.In other words, although in Glass Run 201, form predetermined recess because of control part is set in module 242,243 and 244, but,, can prevent to be formed with in the Glass Run 201 easily deformable the or durability reduction of part of recess because longitudinally the part is provided with control part.
