Pay mold could complete product because the size of head components be in automobiles it is very big, cause to invest larger.
Since the process that the characteristic of metal plate punching manufacturing process needs at least needs five processes that could complete plus blanking,
Need to occupy three press, the personnel of 4 stations.And Same Part needs are processed on three molds, resetting
Accumulated error is caused, product quality is influenced.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide one kind especially suitable for pure
The automobile lamina tecti for the PDCPD material that electric car top cover uses, and corresponding location structure is formed, ease of assembly installation.
It is for technical solution used by realization the purpose of this utility model:
A kind of automobile lamina tecti of PDCPD material, including pass through Shooting Technique integrated injection molding, including lamina tecti sheet
One side of body, the lamina tecti ontology is wider than opposite side, the outer surface of the lamina tecti ontology formed axially arrange it is equal
Even reinforcement convex ribs, the front and rear end of the reinforcement convex ribs form streamlined structure to reduce windage, this lamina tecti sheet
Three outsides of body form connection edge, and the connection is connect along with the top cover body by an inclined-plane docking transition part, institute
Another first downward slope portion of outer formation of lamina tecti ontology is stated, the first downward slope portion connects the second downward slope
Portion, second downward slope portion are connected by curved portion to upper inclined portion.
Fixation hole is installed along upper formation in the connection.
The reinforcement convex ribs are three, parallel uniformly axial setting.
The utility model have the following advantages that and the utility model has the advantages that
1. being similar to Shooting Technique using PDCPD material fabrication process, only using a set of injection mold can be completed manufacture,
Die cost can be saved, original Sheet Metal Forming Technology needs are completed on three molds；
2. the accumulation of fabrication error is so that the quality control difficulty of product is larger, present one set of die is completed, and there is no each
Accumulated error between process；
3. need to occupy an injection molding station, original punching press needs four stamping stations, can save human cost；
4. reducing product weight, the material density of PDCPD is in 1.08g/cm3, steel are in 7.8g/cm3。
For the material of 5.PDCPD under equal design condition, intensity is the several times of steel, and reaching 1.5 dual intensities only needs
To increase to 3.5mm on the basis of former top cover thickness 0.8mm, top resistance to compression can be effectively improved in the case where mitigating weight
Intensity promotes vehicle security.
Edge and structure 6. surrounding formation is located by connecting, ease of assembly, and by the reinforcing rib of setting, structure further increases
By force, and windage is small.
Detailed description of the invention
Fig. 1 show the overlooking structure diagram of the automobile lamina tecti of the PDCPD material of the utility model；
Fig. 2 show the left view structural representation of Fig. 1；
Fig. 3 is the schematic view of the front view of Fig. 1.

Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, the automobile lamina tecti of the PDCPD material of the utility model, including pass through Shooting Technique integrated injection molding
Molding, including lamina tecti ontology 1, a side of the lamina tecti ontology is wider than opposite side, the appearance of the lamina tecti ontology
Face forms the uniform reinforcement convex ribs 5 axially arranged, the front and rear end of the reinforcement convex ribs forms streamlined structure 6 to subtract
Three outsides of few windage, this lamina tecti ontology of institute form connection edge, and the axial connection including axial sides is along 2 and diameter is arranged
To the radially connected along 3 of side, the connection is connect along with the top cover body by an inclined-plane docking transition part, including axis
Transition part 7 is docked to inclined-plane and radial docks transition part 11, the outside one in another outside 9 of the lamina tecti ontology
Body is formed with top cap rear cross beam sealing structure, to shut rear side formation discharge structure in vehicle rear cover, from the two of following ditch body
Outside end discharge vehicle, including the first downward slope portion 10, the first downward slope portion connect the second downward slope portion 8, institute
The second downward slope portion is stated to connect by curved portion 12 to upper inclined portion 4.
Wherein, fixation hole 13 is installed along upper formation in the connection, is connected the docking site of lamina tecti and vehicle body with facilitating
Fitting, such as screw element, are connected.
Wherein, the reinforcement convex ribs are three, parallel uniformly axial setting.
The utility model have the following advantages that and the utility model has the advantages that
1. being similar to Shooting Technique using PDCPD material fabrication process, only using a set of injection mold can be completed manufacture,
Die cost can be saved, original Sheet Metal Forming Technology needs are completed on three molds；
2. the accumulation of fabrication error is so that the quality control difficulty of product is larger, present one set of die is completed, and there is no each
Accumulated error between process；
3. need to occupy an injection molding station, original punching press needs four stamping stations, can save human cost；
