Detailed description of the invention:
Fig. 1 is the concrete structure schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of Fig. 1；
Fig. 3 is the partial enlarged view of another part of Fig. 1；
Fig. 4 is the simplified basic diagram of the utility model.
Specific embodiment:
Embodiment 1 is shown in that as shown in Figures 1 to 4 a kind of mold delayed goring device for reducing deformation, including thimble reset
Bar 1 and die bottom plate 2, the bottom end of the thimble release link 1 pass through the guide through hole 21 of die bottom plate 2 and are fixed with thimble cover board
3, the bottom surface of thimble cover board 3 is fixed with common thimble fixed plate 4, and it is logical that the top surface of thimble cover board 3 forms at least one stairstepping
Hole 31, the diameter of the upper segment of stairstepping through-hole 31 are less than the diameter of lower section, and 5 sleeve of thimble that is delayed is in stairstepping through-hole 31
In, delay 51 sleeve of thimble block that the bottom end of delay thimble 5 is equipped with is in the lower section of stairstepping through-hole 31, and be delayed thimble block 51
Top surface and stairstepping through-hole 31 lower section top surface between molding have gap 6；
The top surface of the common thimble fixed plate 4 forms multiple connection ladder holes 41, connects the upper of ladder hole 41
The diameter for being directly greater than lower section of section, commonly uses 7 sleeve of thimble in the lower section of connection ladder hole 41, commonly uses thimble 7
71 sleeve of upper block that is equipped with of top in the upper segment of connection ladder hole 41；
The top surface of partial upper block 71 is pressed against on the bottom surface of thimble cover board 3, at least one connection ladder hole 41
Corresponding with about 31 stairstepping through-hole, the upper block 71 that is inserted with is pressed against pair in the upper segment of this connection ladder hole 41
On the bottom surface for the delay thimble block 51 being inserted in the lower section for the stairstepping through-hole 31 answered；
The bottom end of all common thimbles 7 is pressed against on the top surface of mould product 100.
Further, the bottom end of the delay thimble 5 forms delay thimble block 51, commonly uses the top molding of thimble 7
There is upper block 71.
Further, the gap 6 is the gap of 5mm and the above height.
Further, the top surface of the thimble release link 1 stretches out the top surface of die bottom plate 2 and is fixed with die casting machine thimble
Plate 8.
Further, the bottom surface of the thimble cover board 3 is fixed with mold rack 10, and the bottom surface of mold rack 10 is fixed with down
Mold base 20, upper mold seat 30 are in the lower section of lower mold base 20, and the top surface of upper mold seat 30 is pressed against the bottom of lower mold base 20
On face, upper mold 40, the bottom surface middle part of lower mold base 20 are installed in the installation groove that the top surface middle part of upper mold seat 30 has
Lower mold 50 is installed, mould product 100 is clamped between upper mold 40 and lower mold 50, lower die in the installation groove having
There are multiple ejection through-holes 501 on tool 50, eject the middle through-hole 201 formed on through-hole 501 and lower mold base 20 and communicate,
The lower part sleeve of common thimble 7 commonly uses the bottom end of thimble 7 close to ejection in corresponding middle through-hole 201 and ejection through-hole 501
The bottom end of through-hole 501.
Working principle: attached drawing is to be inverted setting, in use, upper mold seat 30 is in top and is fixed on the lifting of rack
It on plate, is run by the lifter plate of rack, upper mold seat 30 is promoted, then, promoted by die casting machine ejector retainner plate 8, so that top
Needle cover plate 3 and thimble fixed plate 4 simultaneously so that the common thimble 7 for the thimble 5 that is not delayed top stretch out ejection through-hole 501 simultaneously
By the big part ejection of the enclasping force of corresponding mould product 100, and between the common thimble 7 of opposite delay thimble 5 is due to having
Gap 6 so that its when pushing than being delayed when other common thimbles 7 so that its mould product 100 enclasping force greatly
After partial ejection, the part delayed goring small to the enclasping force of corresponding mould product 100, effect is good, high-efficient, makes mould
Have product deflection after ejection and in the reasonable scope, promotes the quality stability of die-cast product, what reduction was processed and assembled
Rejection rate.
Finally, embodiment of above is merely to illustrate the utility model, and it is not limitation of the utility model, related skill
The those of ordinary skill in art field can also make various changes in the case where not departing from the spirit and scope of the utility model
Change and modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the patent protection model of the utility model
Enclosing should be defined by the claims.
