Description
Technical field
This utility model relates to rubber sulfurizing mould.
Background technology
Rubber in the market is mostly vulcanite, forms stereoeffect, tool after rubber sulfuration
There is higher elasticity, thermostability, hot strength and indissolubility etc. in organic solvent.
The vulcanization of rubber is carried out in sulfurizing mould, and raw-material utilization rate is about by current rubber sulfurizing mould
76%, waste of raw materials rate is higher.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of saving type single-body type rubber sulfurizing mould,
To reach to save rubber raw material purpose.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of saving type single-body type rubber system
Product sulfurizing mould, including upper die and lower die, described lower mold is provided with the lower mold die cavity of upper opening, described upper mold be provided with in upper mold and
Stretch into the upper mold post of drag intracavity after lower mold matched moulds, between described upper mold post and the bottom surface of lower mold die cavity and sidewall, form sulfuration
Die cavity, the oral area of described lower mold die cavity is provided with circumferential step portion, and the top of described upper mold post is provided with and is pressed in circumferential step portion
Peripheral flange portion, the inner peripheral in described circumferential step portion is provided with and becomes sealed lower lock material with peripheral flange portion inner rim dihedral
Chamber, the bottom outer peripheral edge in described peripheral flange portion is provided with the material chamber of locking becoming sealed with circumferential step portion neighboring dihedral.
Preferably, described lower lock material chamber is the V-type or circular arc notch arranged around circumferential step portion inner peripheral.
Preferably, the inner circumferential corner in described circumferential step portion is circumferentially arranged with circumferential notches.
Preferably, lock described in and expect that chamber is to be located at the V-type at peripheral flange portion bottom chamfer or circular arc type notch.
Preferably, described upper die and lower die use T8 carbon tool steel or 45# medium carbon steel to make.
The technical solution adopted in the utility model, arranges material chamber of locking in upper mold, and lower mold arranges lower lock material chamber, due to
Locking and expect chamber and the locking effect in lower lock material chamber, make sizing material only flow at vulcanization type intracavity in sulfidation, it is unnecessary not produce
Side crops, make rubber become single product simultaneously, remove the labor intensity of later stage artificial deburring from, change raw material after structure
Utilization rate is up to 92%.
Accompanying drawing explanation
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structure for amplifying schematic diagram at A in Fig. 1；
Fig. 3 is structure for amplifying schematic diagram at B in Fig. 1.
Detailed description of the invention
As it is shown in figure 1, a kind of saving type single-body type rubber sulfurizing mould, including upper mold 1 and lower mold 2, described lower mold 2
Being provided with the lower mold die cavity 21 of upper opening, described upper mold is provided with the upper mold post stretching into drag intracavity after upper die and lower die matched moulds
11, form the sulfuration die cavity that rubber is vulcanized between described upper mold post 11 and the bottom surface of lower mold die cavity 21 and sidewall.Wherein,
The oral area of described lower mold die cavity is provided with circumferential step portion 22, and the top of described upper mold post is provided with the week being pressed in circumferential step portion
To flange part 12.
The waste of raw materials rate of existing sulfurizing mould is higher, and mainly its structure design is unreasonable.This utility model is to biography
System sulfurizing mould carries out structural change, increases and sizing material carries out sealed lock material chamber, to reach to save rubber raw material mesh
's.Concrete, the inner peripheral in described circumferential step portion is provided with the lower lock material chamber becoming sealed with peripheral flange portion inner rim dihedral
221, the bottom outer peripheral edge in described peripheral flange portion is provided with the material chamber 121 of locking becoming sealed with circumferential step portion neighboring dihedral.
Lock described in as in figure 2 it is shown, and expect that chamber 121 is to be located at the V-type at peripheral flange portion bottom chamfer or circular arc type groove
Mouthful.
As it is shown on figure 3, described lower lock material chamber 221 is the V-type or arc-shaped slot arranged around circumferential step portion inner peripheral
Mouthful, the inner circumferential corner in described circumferential step portion is circumferentially arranged with circumferential notches 222, by arranging under strengthening of circumferential notches 222
The lock material chamber 222 locking effect to sizing material.
Wherein, upper mold post 11 and lower mold die cavity 21 can be circular or square, same, and circumferential step portion 22 circumference is convex
Edge 12 can be circular or square.
Mould structure of the present utility model is not limited to upper die and lower die combination, it is also possible to be 3 layers, upper, middle and lower mould composition
Structure, if 3 layers of mould, does the lock material structure as in lower mold with middle mold joint portion.
It addition, described upper die and lower die use T8 carbon tool steel or 45# medium carbon steel to make.
