Multiple type chambers in the prior art are same type, and since die bottom plate limits, type chamber quantity is also more solid
Fixed, heat dissipation design is not also rationally designed for type chamber different parts, this results in the cooling efficiency of type chamber different parts inconsistent,
And then influence production efficiency and product quality.
Summary of the invention
The purpose of the present invention is to provide a kind of Cavity blow molds with mutually independent swaging die block, have
Flexible configuration, good cooling results, production efficiency and product quality have good advantage.
In order to achieve the above object the technical scheme adopted by the invention is as follows: a kind of Cavity blow mold, comprising: phase
Mutual independent swaging die block, mutually independent refrigerating module, die bottom plate；The refrigerating module is mounted on the mold bottom
On plate, the swaging die block is mounted on the refrigerating module, and the swaging die block, refrigerating module, die bottom plate are equal
It is arranged in pairs.Due to designing using mutually independent swaging die block, thus the type of different number can be set according to production needs
Cavity mold block even different types of swaging die block, so that production has better flexibility, and mutually independent refrigerating module institute
It will not influence cooling effect with swaging die number of blocks.
Heretofore described swaging die block is that die section includes body type cavity block, bottom of bottle pressing block, the body
The lower end of type cavity block is equipped with to be located at described with the matched bottom of bottle pressing block card slot of the bottom of bottle pressing block, the bottom of bottle pressing block
In bottom of bottle pressing block card slot, the body type cavity block includes screw thread position and bottle body position；The screw thread position upper end is set
There is eck mould；Cooling water channel is equipped in the refrigerating module, the cooling water channel includes entrance, outlet and the connection entrance
With the cooling circuit of outlet.Bottom of bottle pressing block is easier to since it is desired that construct blow-molded progress cutoff process compared to other positions
Abrasion is so be separately provided to replace；Eck mould, which plays material and mouth blown, steps up sealing function, so that type chamber internal pressure
Meet forming requirements；The back side of swaging die block is set in refrigerating module, and cooling water channel includes entering described in entrance, outlet and connection
The cooling circuit of mouth and outlet, cooling medium are flowed by entrance, through cooling circuit, by outlet outflow, so that each swaging die
Block can be cooled down effectively and be improved production efficiency and product quality.
The entrance of heretofore described cooling water channel, outlet are located at the lower section of the bottom of bottle pressing block card slot, described
Cooling circuit be located at the position of body type cavity block and bottom of bottle pressing-type cavity block.The entrance of cooling water channel, outlet are located at described
It the lower section of bottom of bottle pressing block card slot can be to avoid the temperature difference between entrance, outlet medium to body type cavity block and bottom of bottle pressing-type chamber
The adverse effect of block, so that body type cavity block is consistent with bottom of bottle pressing-type cavity block cooling effect.
The screw thread position of heretofore described body type cavity block is in the place of turning back of cooling circuit.As of the invention preferred
For scheme screw thread position in the place of turning back of cooling circuit, screw thread position is higher relative to other spot temperatures, thus needs higher
Cooling efficiency, thus the i.e. cooling path in the place of turning back is more intensive compared to other positions for cooling circuit, and cooling efficiency is higher, can be with
Greatly improve the quality of product.
The quantity of heretofore described mutually independent swaging die block can be arbitrarily arranged, and described is mutually independent cold
But the quantity of module is corresponding with mutually independent swaging die block.The quantity of swaging die block, which can be arbitrarily arranged, improves the flexible of production
Property, the quantity of mutually independent refrigerating module is corresponding with mutually independent swaging die block so that each swaging die block obtains effectively
It is cooling, improve the consistency of product.
The type of heretofore described mutually independent swaging die block can be arbitrarily arranged.It can be in a production process
The different product of middle production.
There is adjustment gap between heretofore described refrigerating module and die bottom plate.Gap is adjusted according to each cooling
Module and the different molding effects of swaging die block are adjusted, it is ensured that the leakproofness of molding.
Heretofore described die bottom plate two sides are equipped with mould rack, and the swaging die block and the setting of swaging die block exist
In mould rack.Molding guiding structure is set on mould rack, it is ensured that the stabilization of clamping process and smooth.
It is designed, thus can be arranged according to production needs not using mutually independent swaging die block in technical solution of the present invention
With the swaging die block even different types of swaging die block of quantity, so that production has better flexibility, and mutually independent
Refrigerating module is so swaging die number of blocks will not influence cooling effect；Bottom of bottle pressing block is since it is desired that cut off construct blow-molded
Processing, it is more easy to wear compared to other positions so being separately provided to replace；Eck mould material and mouth blown are played step up it is close
Envelope effect, so that type chamber internal pressure meets forming requirements；The back side of swaging die block, cooling water channel packet are set in refrigerating module
Including the cooling circuit of entrance, outlet and the connection entrance and exit, cooling medium is by entrance inflow, through cooling circuit, by
Outlet outflow, improves production efficiency and product quality so that each swaging die block can be cooled down effectively；The entrance of cooling water channel,
The lower section that outlet is located at the bottom of bottle pressing block card slot can be to avoid the temperature difference between entrance, outlet medium to body type cavity block
With the adverse effect of bottom of bottle pressing-type cavity block, so that body type cavity block is consistent with bottom of bottle pressing-type cavity block cooling effect, swaging die
The flexibility for improving production, the quantity of mutually independent refrigerating module and mutually independent type chamber can be arbitrarily arranged in the quantity of block
Module is corresponding so that each swaging die block is winding is effectively cooled, and improves the consistency of product；Mutually independent swaging die block
Type can be arbitrarily arranged, and different products can be produced in a production process, improves the flexibility of production.
