Description
Technical field
The utility model relates to mould applications, and in particular to a kind of mold convenient for vacuumizing.
Background technique
For the formed product of SMC composite material, usually in compression molding, mold inner-cavity is evacuated to the state of vacuum,
The purpose done so, first is that, second is that air remaining in material is discharged, being mentioned to increase material in the mobility of mould inside
The surface quality of high product.
At present in SMC mould applications, usually mould or rear mold border process seal groove to the structure vacuumized before a mold,
By in sealing strip embedding sealing slot, die face and sealing strip cooperation are to form closed sealing area when molding.This structure
The shortcomings that be: vacuuming action must be consistent with mold clamping, mold clamping to be just able to satisfy when touching sealing strip take out it is true
Dummy status can not form closed area when mold is not closed, vacuuming action is invalid, that is, the limited time vacuumized is closed in mold
The time of conjunction；Vacuumize stroke is influenced by mould steel material height, and steel material height is bigger, and the available stroke that vacuumizes is bigger, to
Increasing vacuumizes stroke, it is necessary to increase steel material height, will cause increasing considerably for die cost.
Utility model content
The utility model is intended to provide a kind of mold convenient for vacuumizing, to solve the deficiencies in the prior art.
The technical problems to be solved in the utility model is achieved through the following technical solutions.
A kind of mold convenient for vacuumizing, including preceding mould and rear mold；The preceding mould lower end side periphery is fixedly installed with one
The lower end surface of border sealing plate and sealing plate is concordant with the lower end surface of preceding mould, and the sealing plate periphery is equipped with a circle sealing ring,
The sealing ring is moved up and down by the drives edge sealing plate of oil cylinder, and the sealing ring is equipped with inner seal circle and bottom side
Sealing ring；The inner seal circle is installed on the inside of sealing ring and is bonded with sealing plate, to realize sealing plate and sealing ring
Between sealing；The rear mold upper end side periphery is fixedly installed with upper surface and the rear mold of a border support ring and support ring
Upper surface is concordant；The bottom side sealing ring is installed on the bottom of sealing ring and is bonded with support ring, with realize support ring with it is close
Sealing between seal ring；Sealing ring is come downwards in the support ring of rear mold by the drives edge sealing plate of oil cylinder, compresses bottom side sealing
Circle is to realize the sealing between preceding mould and rear mold.
Preferably, the sealing ring is formed by square tubes soldering.
Preferably, the support ring is formed by square tubes soldering.
Compared with prior art, beneficial effect possessed by the utility model is: the movement for vacuumizing downlink is driven by oil cylinder
Complete, with mold clamping movement be not directly dependent upon, can independent control, can make sealing ring mold closure before in advance closing, with
Achieve the effect that lengthen the pumpdown time；Sealing ring is moved along sealing plate, the height that stroke depends on sealing plate is vacuumized, with mould
Have steel material height without direct relation, die cost can be saved.
The utility model increases the pumpdown time, increases SMC material in the mobility of mold inner-cavity；It ensure that SMC
Mold inner-cavity is timely discharged in air pocket in material, it is ensured that product appearance bubble-free lacks the defects of material.

Specific embodiment
The design feature of the utility model is further described with specific embodiment with reference to the accompanying drawing.
A kind of mold convenient for vacuumizing, including preceding mould 1 and rear mold 2；The 1 lower end side periphery of preceding mould is fixedly installed with
The one border sealing plate 4 and lower end surface of sealing plate 4 is concordant with the lower end surface of preceding mould 1, it is close that 4 periphery of sealing plate is equipped with a circle
Seal ring 5, the sealing ring 5 are moved up and down by the drives edge sealing plate 4 of oil cylinder 6, and it is close that the sealing ring 5 is equipped with inside
Seal 7 and bottom side sealing ring 8；The inner seal circle 7 is installed on the inside of sealing ring 5 and is bonded with sealing plate 4, to realize
Sealing between sealing plate 4 and sealing ring 5；The 2 upper end side periphery of rear mold is fixedly installed with a border support ring 9 and supports
The upper surface of ring 9 is concordant with the upper surface of rear mold 2；The bottom side sealing ring 8 is installed on the bottom of sealing ring 5 and and support ring
9 fittings, to realize the sealing between support ring 9 and sealing ring 5；Sealing ring 5 is come downwards to by the drives edge sealing plate 4 of oil cylinder 6
