Abstract
The invention discloses a kind of segregative large-scale instrument board slush mold nickel shells and the separation method of resin core model, specifically include following steps：(1) slush mold model is integrally placed at temperature in 320 DEG C~350 DEG C environment, to heat 200 minutes~220 minutes；(2) slush mold model is taken out, then is put into temperature rapidly in 6 DEG C~10 DEG C environment, to cool down 30 minutes~50 minutes；(3) slush mold model is taken out, repeats step (1) and step (2)；(4) slush mold model is taken out, is placed on mould to be divided in the environment of room temperature.Separation method provided by the invention, since resin core model is different from the expansion and contraction of both metallic nickel shells, in this way after the process of high/low temperature cold cycling, with metallic nickel shell interfacial separation will occur for resin core model, so as to easily carry out a point mould using the manual mode for tapping, removing, the difficulty of point mould is thus greatly reduced, can readily carry out a point mould.
Description
Technical field
The invention belongs to auto parts and components manufacture fields, and in particular to a kind of instrument board slush mold nickel shell and resin core model
Separation method.
Background technology
It, when fascia slush mold reaches certain thickness in electroforming pond by way of plating (3mm or so)
Electroformed nickel shell with resin core model is detached, nickel shell mold tool can be obtained in this way, but due to the resin core of fascia
Mode structure is complicated, and model surface is distributed many negative angle and back-off structure, thus after electroforming in separation resin core model and
Very difficult during nickel shell, the present invention proposes a kind of instrument board slush mold nickel shell and resin core model separation method, energy
It is enough easily to detach resin core model with nickel shell.
Invention content
The purpose of the invention is to which slush mold nickel shell is detached with resin core model, a kind of instrument board slush mold is provided
The separation method of nickel shell and resin core model.
To achieve these goals, the present invention provides following technical solution：
The separation method of a kind of instrument board slush mold nickel shell and resin core model, which is characterized in that include the following steps：
(1) slush mold model is integrally placed at temperature in 320 DEG C~350 DEG C environment, to heat 200 minutes~220 points
Clock；
(2) slush mold model is taken out, then is put into temperature rapidly in 6 DEG C~10 DEG C environment, to cool down 30 minutes~50 points
Clock；
(3) slush mold model is taken out, repeats step (1) and step (2)；
(4) slush mold model is taken out, is placed on mould to be divided in the environment of room temperature；
(5) divide mould.
Further, the heating means of step (1) are using oil bath.
Further, the oil bath is dimethicone oil bath.
Further, the cooling means of step (2) is using water-bath.
Further, step (3) number of repetition is 1~2 time.
Further, the temperature that the model described in step (4) is placed at room temperature for is 23 DEG C~25 DEG C, and the time is 24 hours.
Further, the mould-dividing mode described in step (5) is dragged manually to tap and/or tearing.
Compared with prior art the beneficial effects of the invention are as follows：
The separation method of instrument board slush mold nickel shell provided by the invention and resin core model, due to resin core model and metal
The expansion and contraction of both nickel shells is different, and in this way after the process of high/low temperature cold cycling, resin core model will occur with metallic nickel shell
Interfacial separation so as to easily carry out a point mould using the manual mode for tapping, removing, thus greatly reduces the difficulty of point mould
Degree, can readily carry out a point mould.
