Description
Technical field
The present invention relates to casting mould technical field, especially a kind of caliper body pours core frame manufacture craft side under cast moulding
Method.
Background technique
Lower core frame on core setter be for accurately placing sand core in type chamber, only by accurate simulator (
Including lower core frame) close tolerance that moulding machine is operated could be fully utilized, wherein the accuracy of lower core frame directly affects
The surface quality and dimensional accuracy of casting.Core setter skill is improved to machine automatization in the past always by manually core being played to operate now
Lower core, corresponding mold need to be equipped with lower core frame automatically, therefore turn over system and accurately play core frame just and become key therein.
Summary of the invention
It is an object of the invention to provide the process that core frame under a kind of moulding machine makes, this method is made down
Core frame precision is high, good toughness, firm and durable, is advantageous to mechanization and core is played to operate automatically.
Concrete scheme of the invention is: a kind of caliper body pours core frame process for making under cast moulding, including with
Lower step:
The first step turns over plaster master processed, specially following steps:

Or environment-friendlyantirust antirust agent, in favor of demoulding；
1-2, core frame under aluminum and external mold positioning pin stick are positioned, clamping fixture is fixed, surrounding gap release agent or Huang
Oily jointing is filled up, and prevents calcium plaster from leaking；
1-3, allotment calcium plaster, the dosage of usage amount calcium plaster according to required for core frame under mold are subject to that pour into lower core frame flat:
Land plaster and water press 1:1~1:1.3, and water should first be added and place into land plaster stirring, slowly drive bubble out of in whipping process, and
Big plaster block is crumbed, stirring is to calcium plaster exquisiteness without bulky grain；The calcium plaster of uniform stirring is poured under aluminum in core frame
Filling is complete, stand 5~6 hours or more；
1-4, lower core frame plaster master and external mold are separated, core frame under surrounding tapping aluminum, takes out positioning pin stick, use hanging ring when separation
Lock slowly lifts core frame under aluminum in the tension screw hole of core frame under aluminum, and the lower core frame plaster master after taking-up dries in the shade 5 small
When more than, while restoring to turn over the accessory and running gate system on the mold of system, avoid mold from corroding and influence the normal production of mold；
Second step turns over the modern designs of plastics processed, specially following steps:
2-1, it turns over and is inserted into corresponding sand core after the lower core frame plaster master produced dries, and is resistance in the placement metal block increase of sand core surrounding
Mill property, according to the design of the structure of product and mold stop-off piece, deploys sticky calcium plaster and is repaired, to avoid the lower core for system of turning over
Frame occurs to squeeze sand situation；
2-2, one layer of lubricating oil or environment-friendlyantirust antirust agent are smeared on lower core frame plaster master surface, in favor of demoulding, by another block of aluminium
Lower core frame is made to folder, the positioning of positioning pin stick simultaneously clamps on fixture and closes tightly；
2-3, allotment cured epoxy resin: curing agent volume accounting is 17%~30%, and diluent 10~20% is added in point 3 allotments
Increase the mobility of epoxy resin, single blending amount is the amount that single is sufficiently mixed stirring；
2-4, epoxy resin deployed in step 2-3 is slowly uniformly poured into lower core frame plaster master 7~10mm of surface layer thickness
Degree is formed uniformly shell mold with scraper plate smearing, is statically placed in shady place under environment temperature room temperature, avoids directly being exposed to the sun, and 0.5~1 hour
Layer of glass cloth is covered afterwards, it is every to brush one layer of epoxy resin covering to improve the intensity and toughness of epoxy resin plastics mould
Layer of glass cloth divides 3 times and pours into epoxy resin covering layer glass fiber cloth, until epoxy resin pours into core frame height under aluminium
It spends at 4/5, can just be demoulded within placement 10 hours or more after the completion of casting process；
2-5, positioning pin stick is removed, slowly separates two pieces of clip-on lower core frames, after the sand core removal on epoxy resin plastics mould
Polishing treatment, later period are smooth by epoxy resin cleaning extra after foaming；
2-6, suction hole is added in corresponding position according to product structure, to guarantee that lower core process is steady；
2-7, die trial is carried out to core frame the modern designs of plastics under epoxy resin, examines whether production scene can be used normally.
Heretofore described diluent is made of toluene or acetone material.
Ambient temperature chamber temperature is 20~24 DEG C in the present invention.
The upper surface of core frame the modern designs of plastics is equipped with the anti-wear coating of 1~2mm under epoxy resin in the present invention.
Core frame is cast in core frame with epoxy resin under specially designed aluminum standard under overmolded of the invention, frame
The interior shape of frame makes resin keep stable in the frame, there are four bolt hole on frame, for quick locking system and will under
Core frame is clamped on core setter, and similar to the template in moulding machine, frame is carried out by two guide pins on core setter console
Guiding, the case where placement of columnar lengthened guide pin is with template, is identical, and lower core frame manufacturing process is basically manufacture back-pressure
The process of the negative plate of plate.
Present invention process method turns over core frame the modern designs of plastics surface accuracy height under the epoxy resin produced and, high-quality, firm resistance to
With utilization and extention value is high.
