Technical field
The present invention relates to foaming mould technical fields, and in particular to one kind being used for cold sotrage door foaming mould.
Background technology
The mold of foaming is exactly plastic foaming mould, and foaminess resin is directly inserted in mold, it is made to be heated
Melt, form gas-liquid saturated solution, by nucleation, forms a large amount of small complexs, complex increases, and foam plastic is made, and commonly uses
Foaming method there are three types of：Physical blowing method, chemical blowing process and mechanical foaming method.During refrigerator cold-storage pupil production, refrigeration
Filling-foam material is needed between door shell and liner, this process is typically all to be completed in foaming mould.
Existing foaming mould, because during not accounting for foam production, the temperature change and expanding foam solution of mold exist
Mobility in foam chamber can have an impact the quality of foam plastic, so when mold puts into production, be also easy to produce unqualified production
Product cause yield rate not high.
When cold sotrage door previous simultaneously demoulds after expanding, the side of upper die and lower die is all connected using hinge, and another
Side then uses cylinder open-top, and the door body due to easilying lead to upper die and lower die intersection during upper mold is opened goes out
It now scratches, so influencing whether the appearance of door.Pneumatic operation is cylinder due to power source, it is therefore desirable to match air compression station outside,
And it in process of production, needs constantly to consume electric power energy, compressed air is generated by air compressor, simultaneously because
Power source is cylinder, causes failure rate higher, and die cost rises.

It She You not tight locking button corresponding with locking folder.
The upper mold is internally provided with more oil fuel tubes with lower die, by injecting cold and hot oil in oil fuel tube, can make mold
Temperature is stablized.
The foam chamber surface is coated with polytetrafluoroethylene film.
The invention course of work is：By injecting cold and hot oil into oil fuel tube, mold temperature is made to stablize.Door shell will be refrigerated
It is put into lower die, the retractable venthole of cold sotrage door innerliner and retractable material hole is all opened, then in cold sotrage door
Lining is put into upper mold, then upper mold is allowed to move vertically downward, upper and lower mould is made to be closed, and is pulled locking folder, is completed mold closing.Air pump is opened,
So that air pressure in foam chamber is consistently lower than an atmospheric pressure, then inject a certain amount of expanding foam solution into foam chamber by filling tube,
Start to foam.After foaming, locking folder is opened, by the thrust of the first hydraulic cylinder and the second hydraulic cylinder, completes die sinking
And take out the cold sotrage door after foaming, close the retractable venthole of cold sotrage door innerliner and retractable material hole.
(3) advantageous effect
The present invention provides one kind being used for cold sotrage door foaming mould.Has following advantageous effect：By on pedestal upper surface
First hydraulic cylinder of four corners pushes upper mould fixed plate, can be molded by vertical mode, so as to avoid
The scuffing of refrigeration door body.It can in conjunction with the thrust of the second hydraulic cylinder by coating polytetrafluoroethylene film on foam chamber surface
To realize quickly die sinking.Foam chamber is evacuated using air pump, air pressure in foam chamber is made to be consistently lower than an atmospheric pressure, it can be with
Reduce the air resistance in foam chamber, increase the mobility of foamed material so that foam complete, even density.Pass through past oil fuel tube
The interior cold and hot oil of injection, can be such that mold temperature stablizes, improve the quality of foam plastic.Since power source is hydraulic cylinder,
Air compression station need not be matched outside, reduce die cost.
