Description
Technical field
It the utility model is related to the multi-cavity injection mould that a kind of locomotive turns to axial rubber pad.
Background technology
Since the viscosity of rubber is big, poor fluidity, many enterprises still use traditional die pressing molded rubber part, with
The extensive use of rubber, pure rubber product injection moulding are promoted, but iron glue composite members and common pure rubber
Part is different, particularly the iron glue composite members of a variety of ironwares sulfidization molding together with rubber, since process is more, and is chiefly used in railway system
Product, experimental performance require high, a variety of causes such as sulfuration process complexity, and it is to use mould mostly that axis locomotive, which turns to axial rubber pad, at present
Platen press is produced, although injection molding obtains stable vulcanization process condition by experiment, can meet properties of product requirement,
All it is to be produced using single type cavity mould, efficiency is low, it is also necessary to which manual operation, causes production of high cost, in addition, also existing
Problems with：1st, because it uses single-chamber compression-molded structures, there are low production efficiency, and manual operation is complicated, caused by human factor
The problems such as die wear is big, and die life is short, and homogeneity of product is poor；2nd, because L-type ironware is different from middle template fit system,
There are it is different the problem of：（1）L-type ironware faces clearance fit directly with middle template using conventional, and use level is few（On vertical direction
Lower gap is 0.1）, exist and do not take into full account ironware and sizing material under 150 °C of degree vulcanizations, the swell increment of ironware, causes product
It is overall to eject pickup difficulty, or even mold damage cavity after vulcanization, cause damages；（2）It is to adopt that middle template coordinates with L-type ironware
With 1 °, 14 ° of continuous dog-ear, although solving the problems, such as that product ejection is difficult, the spacing gap value of template is big because in（In ironware
Portion has reached 1.48mm with middle die clearance）, because heating expands, the effect of sizing material flow stress concentration causes in ironware L-type ironware
Between it is raised, cause product size overproof；4th, for runner using conventional design, runner is cone, and round hole is presented in glue-feeder
And directly with being connected at the top of cavity, glue-feeder size and the plug-in bondline thickness of resultant metal part are basically identical（Only 2.5mm, hangs
Bondline thickness 2.1mm）, glue-feeder centre distance metalwork edge only 1mm, cause always to accumulate into glue surface it is small, it is difficult there are injecting glue,
Product section misrun, qualification rate is relatively low, wastes raw material, and production cost is high.
The content of the invention
The utility model provides one kind aiming at the above problem can improve production efficiency and yield rate, reduction production and dimension
Accomplish sheet, the locomotive of service life length turns to the multi-cavity injection mould of axial rubber pad.
To achieve the above object, the utility model uses following scheme：Locomotive turns to the multi-cavity injection mould of axial rubber pad
Tool, including the cope plate for opening pressure pin, middle template, lower template, lower mold fixed plate and liftout attachment are provided with, master is set in cope plate
Hole for injecting glue, runner, runner both ends are connected with the cavity set in hole for injecting glue and middle template respectively, its structural feature is that cavity is
It is 8, symmetrical centered on main hole for injecting glue.
Further, 8 middle mould inserts are provided with middle template, with being set respectively in the lower template of middle mould insert relevant position
8 lower die model cores are equipped with, cavity is made of cope plate, middle mould insert, middle template, lower die model core.
Further, runner includes sprue, runner and vertical runner, and the cross of sprue and each cavity shunts
Road center is connected, and runner end is connected with vertical runner respectively.
Further, annular is provided with middle mould insert into glue groove, into glue groove at the top of be connected with vertical runner, its inner side and
Cavity is connected.
Further, vertical cross section of fluid channel is slotted hole, and the upper end is tubaeform, and the diameter of slotted hole is vertical with being connected this
The axis of the runner of runner is parallel.
Further, middle template is matched somebody with somebody from bottom to top with L-type ironware mating surface is combined into 1 °, 3 °, 0 ° of continuous dog-ear, middle template
It is minimum 0.1 mm in lower end with L-type ironware fit clearance, maximal clearance is 0.3 mm.
Further, cope plate, lower die plate thickness are 39 mm.
Further, liftout attachment includes angled slide block fixed plate and 8 angled slide blocks corresponding with die cavity position, angled slide block
Material is aluminium.
The beneficial effect of utility model
1st, using multi-cavity mold injection structure, have and improve production efficiency and utilization rate of equipment and installations, save the energy, reduce manpower
Cost；Cavity layout is symmetrical and compact, can prevent mould from the inconsistent phenomenon of product quality occurring because of pressure-bearing；Main gum-injecting port arrives
The distance of each cavity is consistent, sizing material flow equilibrium；
2nd, middle template at L-type ironware cooperation with, using the small―gap suture of change, both considering fit-up gap, it is contemplated that hot
Swell increment and face the spacing of section directly；Using appropriate gap value and the angle of change, it not only can guarantee that product ejection was smooth, but also will not
Cause product overproof；10mm is thickeied after the bolster of mould at the same time, in sulfidation, heat insulation function can be strengthened, is improved
Product Precision and uniformity；
3rd, using slotted hole vertical runner and increase into glue groove structure, vertical runner is big apart from metalwork edge, and
Glue-feeder shape is changed, and is expanded and is accumulated into glue surface, and cavity can be filled with completely, and starved phenomenon is not present in product, and qualification rate is high；
In addition, using cross vertical runner is distributed, balance is good, advantageously ensures that each cavity fills sizing material, can improve product
Can consistency and stability；
4th, the mould insert in, be damaged to replace in time, reduce use and the maintenance cost of mould；
5th, using aluminum angled slide block, because its hardness is low, mold damage and workpiece can be prevented, improve product qualification rate, drop
Low production, maintenance cost.
