Abstract
The utility model discloses a kind of molding die blank holder of car roof, which is arranged on around the upper mold die face of mould, and the upper surface of the blank holder is equipped with a circle locking muscle, and the locking muscle is the groove of cross section inverted trapezoidal.A kind of molding die of car roof is also disclosed in the utility model, applies above-mentioned blank holder, including upper die and lower die, and the middle part in the upper model face is equipped with groove, a circle blank holder is equipped with around the rectangular recess being located on upper model face；The upper surface of the blank holder is equipped with a circle locking muscle, and the locking muscle is the groove of cross section inverted trapezoidal.The utility model makes exhaust and air inlet more smooth, reduces surface quality of workpieces and the probability of defect occur by the way that upper mold is locally emptied；And by the utilization of locking muscle, reduce cavity plate type face, accelerate the inflow of air, reduce the time existing for negative pressure.
Description
Technical field
The utility model belongs to machinery equipment field, and in particular to a kind of molding die blank holder of car roof and into
Pattern has.
Background technology
Covering for roofs is necessary for holotype face using punch-pin and cavity plate pressing and forming, cavity plate with punch-pin.In bonding processes, air
It is discharged, the space of sealing can be formed between plate and cavity plate；For cavity plate during opening, air is unable to Fast Filling, shape
Into negative pressure, i.e. the pressure of cavity plate is less than atmospheric pressure, and plate is adsorbed on cavity plate.As cavity plate rises, air gradually fills up recessed
Mould, negative pressure eliminate, and plate drops by dead weight.In such case, the production frequency is no more than 10 beats/min.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of the molding die blank holder and molding die of car roof,
By the way that upper mold is locally emptied, make exhaust and air inlet more smooth, reduce surface quality of workpieces and the probability of defect occur；And pass through
The utilization of locking muscle, reduces cavity plate type face, accelerates the inflow of air, reduce the time existing for negative pressure.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
The molding die of the car roof of the utility model is arranged on blank holder around the upper mold die face of mould, the pressure
The upper surface of flange is equipped with a circle locking muscle, and the locking muscle is the groove of cross section inverted trapezoidal.
The present invention also provides a kind of molding die of car roof, applies above-mentioned blank holder, including upper die and lower die, institute
The middle part in the upper model face stated is equipped with groove, and a circle blank holder is equipped with around the rectangular recess being located on upper model face；It is described
Blank holder upper surface be equipped with one circle locking muscle, the locking muscle be cross section inverted trapezoidal groove.
Further, the bottom of the groove is equipped with more than one exhausting-gas hole.
Further, the exhausting-gas hole uniform intervals are arranged at the bottom of groove.
Further, the groove is rectangular recess.
The course of work of the utility model is as follows：
Upper mold and lower die are pressed, in bonding processes, air is discharged from the gap between upper die and lower die and exhausting-gas hole, lock
Only muscle is molded by the extension of material itself, after locking muscle, it is only necessary to relies on lower mold forming, upper model face is locally emptied
Rectangular recess is formed, and the type face of member-retaining portion ensures dimensional accuracy.
The beneficial effects of the utility model are：
The utility model is emptied to form groove, exhausting-gas hole is added in groove by cleverly designing on upper model face,
So that upper parting line venting, air inlet are smooth, the situation of upper mold suction when being not in production；Groove causes upper mold not contact zero at the same time
Part, will not be weighed wounded there is a situation where part and caused by production environment point generation, reduce surface quality of workpieces there is defect
Probability.After retaining local profile, emptying for casting is added, when mould produces, the inflow velocity of air is accelerated, and negative pressure is deposited
Time shorten, production the frequency bring up to 16 beats/min.
The utility model is simple in structure, easy to operate, and cost is low, highly practical, securely and reliably.

Embodiment
The utility model is described in detail below by specific embodiment.
Embodiment 1
As shown in Figs. 1-3, the molding die blank holder of the car roof of the utility model, the blank holder are arranged on mould
Around 1 die face of upper mold of tool, the upper surface of the blank holder 3 is equipped with a circle locking muscle 5, and the locking muscle 5 is transversal
The groove of face inverted trapezoidal.
Such as the molding die of the car roof of Fig. 4-5 present invention, above-mentioned blank holder, including upper mold 1, lower die 2, institute are applied
The middle part in the upper model face 11 stated is equipped with groove 12, and a circle flanging is equipped with around the rectangular recess 12 being located on upper model face 11
Circle 3；The upper surface of the blank holder 3 is equipped with a circle locking muscle 5, and the locking muscle 5 is the groove of cross section inverted trapezoidal.
The bottom uniform intervals of the groove 12 set more than one exhausting-gas hole 4.The groove 12 is rectangular recess.
The course of work of the utility model is as follows：
Upper mold 1 and lower die 2 are pressed, in bonding processes, air is from 4 row of the gap between upper mold 1, lower die 2 and exhausting-gas hole
Go out, locking muscle 5 is molded by the extension of material itself, after locking muscle 3, it is only necessary to be molded by lower die 2, upper model face
11 it is local empty to form rectangular recess 12, and the type face of member-retaining portion ensures dimensional accuracy.
