As shown in figure 1, more and more passenger cars now, because of the convenience needs that rear passenger is got on or off the bus, during design model Back door is crossed on rear shaft center's line with gusset C post parting lines, and typical representative vehicle is two boxcars and SUV.However, in back door Plate is longer across rear tyre radian, and cracking and corrugated risk is bigger during forming parts.
Back door inner panel forming process it is cracking and corrugation the problem of often influenceed by following factor:1. material, 2. back doors Inner panel height, 3. art shapes drawing depths, 4. technical face complexities, 5. briquetting pressure sizes, 6. material feed rates, 7. Mold surface roughness, 8. mold materials, 9. gaps, 10. drafting angles, 11. product R angles sizes, 12. scantlings.Wherein, Plate material is chosen in process of production in back door is defined, it is impossible to which change is replaced.Back door inner panel height and product R angles, During vehicle structure general arrangement and product-forming design typification, change can not be adjusted.
Utility model content
In view of this, the utility model provide it is a kind of reduce back door inner panel cracking and corrugation risk be used for produce back door The mould and back door inner panel of inner panel.
In order to achieve the above-mentioned advantages, the utility model provides a kind of mould for being used to produce back door inner panel, it includes being used to produce C Second mold of first mold in post parting portion and the side of sidewall portion for producing covering rear tyre, the first mold and second Mold is connected, and several grooves for being used to absorb more clouts of side of sidewall portion in drawing process are provided with the second mold.
Further, groove includes two linear oblique line portions and connects the arc sections of two oblique line portions, two oblique line portions difference Extension is tilted from the end of arc sections to the direction away from arc sections.
Further, the depth of groove is 3-5mm.
Further, the length of the oblique line portion of groove is 32.48mm, and the arc length of arc sections is 52.17mm.
Further, the number of groove is four.
Further, the utility model also provides a kind of back door inner panel, and it includes C post parting portions and for covering rear tyre Side of sidewall portion, C post partings portion is connected with side of sidewall portion, and back door inner panel utilizes the mould as described above for being used to produce back door inner panel Make, several recesses corresponding with groove are formed in side of sidewall portion.
Further, recess includes two linear oblique line mouths and connects the arc opening of two oblique line mouths, two oblique line mouths difference Extension is tilted from the end of arc opening to the direction away from arc opening.
Further, the depth of recess is 3-5mm.
Further, the length of the oblique line mouth of recess is 32.48mm, and the arc length of arc opening is 52.17mm.
Further, the number of recess is four.
In summary, due to being provided with several grooves in the second mold, the groove can absorb side wall in drawing process More clouts in portion, this can reduce back door inner panel cracking and corrugated risk.In addition, by setting two linear oblique lines in groove The arc sections of two linear oblique line portions of portion and connection, the overall length of groove can be increased, so as to increase more clouts of side of sidewall portion Uptake, this can further reduce back door inner panel cracking and corrugated risk.
Brief description of the drawings
Fig. 1 is the structural representation of the back door inner panel of prior art.
Fig. 2 is the schematic diagram of the back door inner plate structure of the embodiment of the utility model one.
Fig. 3 is the schematic front view of the recess of the embodiment of the utility model one.
Embodiment
Further to illustrate that the utility model is to reach technical approach and effect that predetermined purpose of utility model is taken, Below in conjunction with drawings and Examples, to specific embodiment of the present utility model, structure, feature and its effect, describe in detail such as Afterwards.
The mould of the present utility model for being used to produce back door inner panel includes being used for the first mold for producing C post partings portion 1 With the second mold of the side of sidewall portion 2 for producing covering rear tyre, the first mold is connected with the second mold., Two molds portion is provided with several grooves for being used to absorb more clouts of side of sidewall portion 2 in drawing process.
Groove includes two linear oblique line portions and connects the arc sections of two linear oblique line portions, two linear oblique lines Portion tilts extension from the end of arc sections to the direction away from arc sections respectively.The depth of groove is 3-5mm, the linear pattern of groove The length of oblique line portion be 32.48mm, the arc length of arc sections is 52.17mm, and the number of groove is four.Oblique line portion and arc sections End it is tangent.
In addition, as Figure 2-3, back door inner panel of the present utility model includes C post partings portion 1 and for covering rear tyre Side of sidewall portion 2.C post partings portion 1 is connected with side of sidewall portion 2.The back door inner panel is by the present embodiment for producing back door inner panel Mold Making, four recesses 3 corresponding with groove are formed in side of sidewall portion 2.Recess 3 includes two linear oblique line mouths 31 and connected The arc opening 32 of two linear oblique line mouths 31 is connect, two linear oblique line mouths 31 are respectively from the end of arc opening 32 to away from circle The direction of nock 32 tilts extension.In the present embodiment, specifically, the linear oblique line mouth 31 positioned at the left side is from arc opening 32 Left end inclined upward extends to the left, the linear oblique line mouth 31 positioned at the right is from the right-hand member of arc opening 32 inclined upward to the right Extension.The depth of recess 3 is 3-5mm, and the length of linear oblique line mouth 31 is 32.48mm, and the arc length of arc opening 32 is 52.17mm。
