Specific embodiment
The high molecular material note of refrigeration demoulding can be heated referring to a kind of Figure of description 1 to 7 pairs of attached drawing type cores of the invention
Mould is described in detail below.
A kind of type core can heat the high molecular material injection mold of refrigeration demoulding, including cover half 1, dynamic model 2, pressing plate 3, type core
Component 4, which is characterized in that the cover half 1 is interlocked with dynamic model 2, and the core package 4 penetrates the sky that dynamic model 2 and cover half 1 fasten
In, the core package 4 is fixed on 2 top of dynamic model by pressing plate 3；The core package 4 includes type core housing 40, type in-core
Gallbladder 41, thermal resistance washer 42, capping 43, refrigerating fluid connector 44, molding bolt 45, heater strip 46, the type in-core gallbladder 41 are placed in type
It in core housing 40 and is connected by screw to, the heater strip 46 is wound in 41 outside of type in-core gallbladder, and the capping 43 is tightened against type
It is pushed up on in-core gallbladder 41, has the thermal resistance washer 42 being nested on type in-core gallbladder 41 between the capping 43 and type in-core gallbladder 41, it is described
It covers 43 upper ends to twist there are two refrigerating fluid connector 44, sets that there are two molding bolts 45 on the type in-core gallbladder 41 on end plate.
Further, the intermediate position of the dynamic model 2 is equipped with the through-hole for installing core package 4, and through-hole lower section is cylinder
Hole portion, through-hole upper section are circular cone hole portion, and four blind threaded holes for installing pressing plate 3 are distributed in through-hole surrounding.
Further, the type core housing 40 of the core package 4 is the shell of inner hollow, and type core housing 40 is from the bottom up
It is followed successively by lower cylindrical portion, conus portion, upper cylindrical portion, cylinder pan portion, the outer diameter of the lower cylindrical portion of type core housing 40 and conus portion lower end
Outer diameter is equal, and conus portion upper end outer diameter is greater than lower end outer diameter, and upper cylindrical portion outer diameter is equal to conus portion upper end outer diameter, in cylinder pan portion
