Specific embodiment
With reference to the accompanying drawing, by the description of the embodiment, making further specifically to a specific embodiment of the invention
It is bright.
A kind of forming method of car refrigerator insulating layer, includes the following steps:
A, the external mold 10 of open-close type is provided and inside contracts and extend out the core model 20 of formula；
B, inner container of icebox 1 is set on the core model 20 for the state of inside contracting when external mold 10 opens wide；
C, external mold 10 is enclosed, the outer expanded support of core model 20 consolidates inner container of icebox 1；
D, foamed material is injected into forming cavity at self seeding hole；
E, after foaming solidification, external mold 10 is opened wide, core model 20 is inside contracted, takes out molded part.
In the present embodiment, core model 20 includes movable part 20a and fixed part 20b, and fixed part 20b includes pedestal and is set to seat
Top plate above body, pedestal are located at below movable part 20a, and the opening's edge of inner container of icebox 1 is bonded with the outer peripheral surface of aforementioned pedestal, make ice
Case liner 1 can be steadily set on the interior core model 20 to condense.
In stepb, the top type face paste of the inner wall bottom surface and core model 20 that are set in the inner container of icebox 1 on core model 20 is closed,
I.e. the bottom wall of inner container of icebox 1 is bonded with aforementioned top plate, so that the bottom wall of 20 inner container of icebox 1 of core model is provided secure support, is avoided ice
The damage of product quality caused by 1 extrusion of case liner.
In step C, the external mold that is first closed the first external mold side plate 11 positioned opposite and is connected on the first external mold side plate 11
Then top plate 13 installs outcase of refrigerator 2, is closed the second external mold side plate 12 positioned opposite, outcase of refrigerator 2 is pressed on outside first
Mould side plate 11, external mold top plate 13 side end face on.Both be avoided that in this way the first external mold side plate 11, external mold top plate 13 be closed when with
Loose outcase of refrigerator 2 interferes, and outcase of refrigerator 2 can be made to be installed in place, and guarantees close between outcase of refrigerator 2 and external mold 10
Envelope.
In the present embodiment, while the first outboard template 11 closure, the driving movement of core model 20 makes core model 20 to position is extended out
Side type face be bonded with the inner wall side of inner container of icebox 1, the side wall for inner container of icebox 1 provides support.In other embodiments,
Core model 20 can also inject any moment before foamed material in forming cavity and act to extending out position.
In step E, successively opening the second external mold side plate 12, external mold top plate 13, the first external mold side plate 11 makes at external mold 10
In opening-wide state.In other embodiments, external mold top plate 12, the first external mold side plate 12 can also be first opened, or is opened simultaneously outer
Each plate body of mould 10.
In the present embodiment, when the first outboard template 11 opens wide, the driving movement of core model 20 is condensed to interior, makes the side of core model 20
Portion type face is separated with the inner wall side of inner container of icebox 1.In other embodiments, core model 20 any moment can also be moved before demoulding
Work condenses to interior.
In step E, when external mold 10 opens wide, core model 20 inside contracts, the movement of liftout plate 30 positioned at 3 bottom of insulating layer is extremely ejected
Position, molding insulating layer 3 and the inner container of icebox 1 being coupled as one with it, outcase of refrigerator 2 are ejected together, and operating personnel will be at
Product remove completion demoulding from core model 20, then drive the movement of liftout plate 30 to molding position.The ejection height of liftout plate 30 is higher than
The pedestal of fixed part 20b, such liftout plate 20 can be such that inner container of icebox 1 and the pedestal of fixed part 20b separates when ejecting, to protect
Demonstrate,prove reliable, the convenient demoulding of molded part.
