Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below with reference to examples and drawings further
Explanation, the content that embodiment refers to not is restriction to the utility model.
A kind of hot-die for automobile decoration lid, as shown in Figure 1, including pedestal 1, being arranged on pedestal 1 for forming
The set of molds 2 of automobile decoration lid and for pressing set of molds 2 to form the pressing assembly 3 of trim, for heating mould group 2
Heating member.Set of molds 2 includes lower die 21 and upper mold 22, and lower die 21 is fixed on pedestal 1, and 21 top surface of lower die is formed with to recessed
Sunken half chamber 211 (referring to Fig. 2) of lower molding, 22 bottom surface of upper mold are formed with half chamber 222 of upper molding being recessed upwards (referring to Fig. 3)；
Lower die 21 and with 21 male-female engagement of lower die so that half chamber 211 of lower molding and half chamber 222 of upper molding are formed decorates for formed automobile
Lid forming cavity (does not regard out) in figure.The inner wall of half chamber 222 of inner wall and upper molding of half chamber 211 of lower molding offers multiple ventilations
Hole 5 (referring to Fig. 2) is provided with air pump (not showing in figure) on pedestal 1, and air pump is equipped with multiple gas-guide tubes and is connected with venthole 5
It is logical.
The sample of filling manufacture trim in forming cavity, then makes upper mold 22 together with the concave-convex adaptation of lower die 21, opens
Dynamic pressure seaming element 3 and heating member progress are hot-forming, and heating member is to mold while pressing assembly 3 applies pressure to set of molds 2
Group 2 heats so that sample reaches molten condition, then booster air pump air-breathing, air pump by the extraction of venthole 5 decoration cap surface with
The air between cavity wall is formed, decoration cap surface after processing is completed is avoided uneven phenomenon occur or form endless
It is whole.After trim to be formed is cooling, booster air pump is blown, and it is de- that the high pressure gas blown out from venthole 5 facilitates trim
It is conveniently stripped from half chamber 222 of half chamber 211 of lower molding and upper molding.It, should compared to the method for using the explosive demoulding of muti-piece mold
Scheme can reduce the lapping defect quantity of automobile decoration cap surface, improve the aesthetics of automobile decoration lid.
Specifically, referring to Fig. 2, in order to avoid automobile decoration cap surface after molding occur being not belonging to it is formed in mould convex
The diameter of block, venthole 5 is less than 1mm.Multiple ventholes 5 are evenly distributed on half chamber of inner wall and upper molding of half chamber 211 of lower molding
On 222 inner wall, decoration cap surface after processing is completed is avoided uneven phenomenon occur.Meanwhile in half chamber 211 of lower molding
The recess of inner wall of half chamber 222 of inner wall and upper molding be equipped with venthole 5, sample can be entered into when facilitating hot pressing
The place of type cavity wall recess keeps sample molding complete.
Referring to Fig.1, pressing assembly 3 includes four guide posts 31, force fit plate 32 and hydraulic cylinder 33.Four guide posts 31 are distinguished
1 upper end two sides of pedestal are fixed on vertically, there are two on each side；Force fit plate 32 and four 31 sliding plugs of guide post；Four guide posts 31
Top be fixed with fixed plate 34, hydraulic cylinder 33 is fixed on the lower end surface of fixed plate 34, the piston rod of hydraulic cylinder 33 and pressing
Plate 32 is fixedly connected, and force fit plate 32 can be driven to slide up and down along guide post 31 for hydraulic cylinder 33 so that the pressing of force fit plate 32 or disengaging
Upper mold 22.Here it uses four guide posts 31 for the guiding of force fit plate 32, pushes force fit plate 32 more under the driving of hydraulic cylinder 33
Add steadily, keeps sample molding more accurate.
In conjunction with Fig. 1 and Fig. 3, when pushing upper mold 22 under the driving of hydraulic cylinder 33 in order to avoid force fit plate 32, force fit plate 32
There may be dislocation between upper mold 22, and the substandard products of automobile decoration lid are generated after hot-forming, in the two sides point of 22 top surface of upper mold
It She Zhi not be opened up there are three locating rod 221, the bottom surface of force fit plate 32 there are six the location hole 321 being adapted to 221 grafting of locating rod,
The bottom surface of one of location hole 321 is provided with the trigger switch 322 for controlling heating member starting, when force fit plate 32 is hydraulic
Upper mold 22 is compressed under the driving of cylinder 33, locating rod 221 is plugged into location hole 321, and the top of locating rod 221 abuts trigger switch
When 322, set of molds 2 is heated in heating member starting.If there is dislocation between force fit plate 32 and upper mold 22, force fit plate 32 exists
When pushing upper mold 22 under the driving of hydraulic cylinder 33, locating rod 221 cannot be plugged into location hole 321, and heating member will not open
Dynamic, the sample in forming cavity will not be melted, and avoid the waste of the energy.
Preferably, the upper end of upper mold 22 is also equipped with the coldplate 6 for cooling down upper mold 22, is equipped in coldplate 6 S-type
Cooling tube 61, the both ends of cooling tube 61 protrude from coldplate 6 respectively, can connect water-supply-pipe to cold at the both ends of cooling tube 61
But 61 water flowing of pipe, and then cool down to set of molds 2, cooling tube 61 is S-type, extends flowing of the cooling water in coldplate 6
Time improves cooling efficiency.
As shown in Fig. 2, heating member includes the electromagnetic heating coil 4 being mounted in lower die 21, electromagnetic heating coil 4 around it is lower at
The surrounding of half chamber 211 of type.Workpiece sample is heated using electromagnetic heating coil 4, compared to Resistant heating, heating efficiency
Height saves electric energy.
Working principle: firstly, filling manufactures the sample of trim in forming cavity, make upper mold 22 and the concave-convex adaptation of lower die 21
Together；Then, start pressing assembly 3 and heating member progress is hot-forming, pressing assembly 3 applies set of molds 2 stressed same
When heating member to set of molds 2 heat so that sample reaches molten condition；Then, booster air pump air-breathing, air pump are taken out by venthole 5
Cap surface is decorated out and forms the air between cavity wall, avoids decoration cap surface appearance after processing is completed rough existing
As or molding it is imperfect；Finally, water flowing cools down to set of molds 2 in cooling tube 61 after waiting the sample of meltings to fill up forming cavity,
After trim to be formed is cooling, booster air pump air blowing mould release.It is de- that the high pressure gas blown out from venthole 5 facilitates trim
It is conveniently stripped from half chamber 222 of half chamber 211 of lower molding and upper molding.It, should compared to the method for using the explosive demoulding of muti-piece mold
Scheme can reduce the lapping defect quantity of automobile decoration cap surface, improve the aesthetics of automobile decoration lid
To sum up, multiple ventholes are offered using the inner wall of half chamber 222 of inner wall and upper molding in half chamber 211 of lower molding
5, air pump is provided on pedestal 1, air pump is equipped with multiple gas-guide tubes and is connected with venthole 5, when hot-forming, booster air pump at
Type chamber air-breathing, can make the sample of molten condition be filled in each corner of forming cavity, and the defect rate that mold generates is low；Demoulding
When, booster air pump blows to forming cavity, and the high pressure gas blown out in venthole 5 facilitates trim and is detached from half chamber 211 of lower molding
It is conveniently stripped with half chamber 222 of upper molding.
Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides
Formula realizes that any obvious replacement is in the protection model of the utility model without departing from the concept of the premise utility
Within enclosing.
