Existing injecting type vulcanizing/forming mode, it is direct one-shot forming, product has injection point, the later stage is needed to carry out grinding or other post processing mode, in material chamber, also have a layered material in addition can slattern, and the weight of this material slatterned quite with the rubber weight utilized on product can be have several times or even tens times, this thisly adds the intrinsic a kind of defect of sulphur mode.Improve this defect just to need to develop new mould.
Utility model content:
The purpose of this utility model is to provide a kind of press injecting type molded rubber product mould, can lower the waste of sulphur.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of press injecting type molded rubber product mould, comprise holding pad, pressure injection plate, lower plate, described lower plate die cavity, is provided with gold utensil in die cavity, and described lower plate is provided with guide column sleeve; Described pressure injection plate is provided with binder groove, and binder groove is provided with material hole, the gold utensil of the corresponding lower plate in position of described material hole; Described pressure injection plate is provided with guide pillar; Described holding pad is provided with the binder block corresponding with described binder groove; Also comprise moulded board, described moulded board mates with described lower plate.
Described moulded board is also provided with the guide pillar mated with described guide column sleeve.
On described moulded board, the position of corresponding gold utensil is provided with core rod.
Before beginning vulcanizing/forming, holding pad, this two boards of pressure injection plate do not carry out preheating, and this two boards of lower plate, moulded board is placed on preheating in vulcanizing machine.
When starting to add sulphur, rubber is put in the binder groove of pressure injection plate, then the first stage is carried out---the pressure injection stage, binder block press-in binder groove, the material of material hole injects die cavity gold utensil position, wherein positioning guide column, guide column sleeve need and compare wide arc gap, prevent holding pad, pressure injection plate from expanding after temperature rises and cause snap gauge, the time of first stage needs to get hold of, cannot be oversize, oversize meeting causes holding pad, pressure injection plate temperature to rise, and affects rubber stability, too short material can be noted discontented, so a time during pressure injection needs to get hold of.
Second stage---the rubber curing forming stage, holding pad, pressure injection plate need after taking out to carry out cooling process, moulded board directly and lower plate matched moulds, carry out vulcanizing/forming, moulded board does core rod, because press injecting type is all generally produce precision part, does core rod and can prevent mould from damaging the envelope mould caused, affect production efficiency.Moulded board guide pillar mates with the guide column sleeve in lower plate.
Then repeat to start the first stage, wherein in holding pad, pressure injection plate, remaining material can carry out secondaryly adding sulphur, can not affect the performance of material.
The Main Function of this utility model is the rubber waste reducing traditional press injecting type sulfidization molding production technology, in order to reach this object, whole sulfuration process is split, when first stage pressure injection, whole pressure injection plate and holding pad are in normal temperature state, do not heat, and the preheating on vulcanizing machine of moulded board and lower bolster, so when pressure injection, pressure injection plate and holding pad are normal temperature and our lower plate is more than 165 DEG C, so pressure injection time first time is shorter, after completing pressure injection, pressure injection plate and holding pad to be taken out in time, place on one side cooling, put the sulfidization molding that moulded board carries out second stage again.The most important thing is once to add the time of sulphur and the cooling to pressure injection plate and holding pad in whole process, these two is crucial.On pressure injection plate, remaining material can also carry out secondary pressure injection, because pressure injection plate and holding pad are normal temperature, lower the temperature in time, so material does not play vulcanization reaction, can ensure the stability of material after carrying out a pressure injection to this two boards.
The utility model greatly reduce material waste rate, saved production cost, and what adopt is moulded board sulfidization molding, thus on the surface of product, does not have decanting point, improves the quality of product.
