Accompanying drawing explanation
Fig. 1 is the structural representation of the manufacture craft of core mould plastic-like core of the present invention.
Fig. 2 is the flow chart of the manufacture craft of core mould plastic-like core of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
The plastic-like core that the manufacture craft of the core mould plastic-like core of the specific embodiment of the invention can manufacture a kind of lighter in weight carrys out the core assembly checking that alternative core carries out sand mold casting mold, thus solve that production line stops production, core is heavier, production line or the problem such as the road between production scene and mould factory is far away.
Wherein, the checking (the oil gas core etc. as cylinder of diesel engine) of thinner for core, long, thin sand mold casting mold, core mould plastic-like core adopts the good epoxy resin of intensity to make plastic-like core.The checking (main core as cylinder of diesel engine) of larger for core, heavier sand mold casting mold, core mould plastic-like core adopts a kind of outer surface to have some strength, meets the Foamex plastic-like core of checking needs.
As shown in Figure 2, comprising the following steps according to the manufacture craft of the core mould plastic-like core of the specific embodiment of the invention:
1) steam vent of patrix, is made;
As shown in Figure 1, after new mould polishing completes, before not filling venting plug, original for upper mould 1 exhaust consent 11 is sealed with plasticine and pulled out and equals shape, and again open a steam vent in centre, the diameter of this steam vent is ф 5mm ~ ф 8mm.
2), shutoff sand-spraying hole;
With the Plastic cap 2 shutoff sand-spraying hole made in advance, the centre of this Plastic cap is with the through hole of ф 5mm ~ ф 8mm.
3), lower plunger tip is reduced;
Lower plunger tip 3 is reduced by 5 ~ 10mm from original plunger tip position, then seals with plasticine and pull out and put down predetermined shape.
4) the exhaust consent of counterdie, is sealed;
The exhaust consent plasticine of counterdie 4 is sealed and pulled out and puts down predetermined shape, counterdie 4 does not need the pore that begins to rehearse.
5), upper releasing agent;
Thin layer releasing agent is evenly coated at the die joint of upper/lower die and cavity surface.This releasing agent can select 2605-QV5110/ packing agent QV5110 or butter fat.
6), upper/lower die matched moulds;
As shown in Figure 1, on patrix 1, cup 12, overflow pipe 13 and collection container 14 are watered in installation respectively.
7), water;
Wherein, for thin, long, thin plastic-like core, the good epoxy resin of intensity is adopted to make, wherein: epoxy resin (Gen Cast3010R) is 1:0.2 with the weight ratio of curing agent (Gen H61).For comparatively large, heavy plastic-like core, except adopting the good epoxy resin of intensity to make, a kind of outer surface can also be adopted to have some strength, meet the Foamex plastic production of checking needs.Wherein, epoxy resin (RENLAM M-1) is 1:(0.14 ~ 0.2 with the weight ratio of curing agent (REN HY 956)); Foamex (Gen R132-2) and curing agent (Gen H132-1) weight ratio are 1:0.2.
The following list ratio of epoxy resin, Foamex and curing agent weighs:
Table one, the density of sample core is 1.1 х 10
-6kg/mm

| Mold cavity volume | Gen Cast3010R epoxy resin | Gen H61 curing agent |
| a | 1b | 0.2b |
Table two, the density of sample core is 0.554 х 10
-6kg/mm

Add appropriate mill base or paint according to the needs of color, make plastic-like core have different colors as required, by different colors when cored is checked, be embedded in the sample core of depths below, can distinguish soon from crack is the shape of that sample core.
Load weighted material is fully stirred, after having stirred, pours pouring container 15 into from stirred vessel.Finally, watered to watering cup 12 by pouring container 15, watering time controls to complete in 25 minutes.
8), die sinking;
Open time is 12 ~ 15 hours under 25 ° of conditions, is 2 ~ 3 hours under 40 ° of conditions.
Before die sinking, first the plastics electric hand drill watered in cup 12, row's consent 11, overfall on patrix 1 is bored.Use jack after the pine of upper and lower mould top again, patrix is hung out and opens.The plastics overflowing die joint are utilized to check die joint gap.The lower plunger tip bar 31 of recycling ejects plastic-like core 5 from counterdie 4.Finally the plug of patrix sand-spraying hole is got recovery, the plasticine of counterdie and patrix is taken out recovery.
9), mold cleaning totally, former state is recovered;
10), plastic-like core 5 is arranged.
To sum up, the manufacture craft of this core mould plastic-like core can produce the plastic-like core of lighter in weight, carry out the core assembly checking that alternative core carries out sand mold casting mold, because this plastic-like core does not need to make to production line, the normal production of production line can not be have impact on, reduce the manufacturing cost of sand mold casting mold.In addition, plastic-like core quality is light, and large core is substituted by it, does not need crane to assist, convenient operation in cored checking.Also have, being produced on Making mold producer and just can completing of plastic-like core, and after carrying out trying core assembly, the size of core assembly, core assembly, carry out a series of inspections such as pressure mud bar inspection part wall thickness dimension, when inspection is pinpointed the problems and maybe will be adjusted, just can change at once, reduce the logistics back and forth between manufacturer and mould factory.Plastic-like core can retain makes archives sample core, and inspection afterwards, change provide foundation.Plastic-like core provides perceptual knowledge when product can be provided to change, change on plastic-like core in advance suitable after, remake the change of mould.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
