Abstract
The invention discloses a method for manufacturing metal molds used for casting manganese steel crushing walls or rolling motor walls of cone crushers. The method is characterized by comprising the following steps of: (1) manufacturing cast molds according to different sizes, specifications and models of the manganese steel crushing walls or the rolling motor walls of the cone crushers; (2) respectively designing and manufacturing near inner metal molds and near outer metal molds which have corresponding thicknesses and overall structures according to the shapes of the cast molds; and (3) distributing trumpet-shaped vent holes on the near inner metal molds and the near outer metal molds. Castings produced by using the method do not produce fragmentation; the metal molds can accelerate the cooling speed of the castings so that the surfaces of the castings have fine grain structures; and the mold cavities have the characteristics of high size precision, bright and clean surface and no distortion.
Description
Technical field
The present invention relates to casting, particularly a kind of manufacture method that is used for the metal mold of broken wall of gyratory crusher manganese steel or rolled mortar wall casting.
Background technology
At present, the broken wall of domestic production, rolled mortar wall potassium steel wear resistance castings, the casting method of particularly medium-and-large-sized cone crushing wall, rolled mortar wall foundry goods mainly contains: limestone sand waterglass CO
2Manual strickle moulding hardens; Quartz sand waterglass CO
2Method for curing is with sandbox, natural pattern hand moulding.Its main method process is: assemble outer sandbox, natural pattern, interior sandbox → on the natural pattern surface apply fill out certain thickness facing sand → the foundry goods working face put certain thickness and quantity every sand cooling iron → filling floor sand and the reality of pounding → blow CO
2Sclerosis → molding → repair type → inside and outside sand mold surface brush coating, surface drying → mould assembling → cast → cooling → peeling etc.
In above-mentioned casting process, in order to play chilling action, quicken casting solidification speed, on the facing sand layer that natural pattern laid, put 40～50mm more than two thickness every sand cooling iron, recharging floor sand outside sand cooling iron, this lay by hand is every the method for sand cooling iron trivial operations not only, and efficient is low, and the facing sand thickness parameter that lays of natural pattern is difficult to control, makes casting quality can not get guaranteeing.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, and a kind of moulding mechanization that realizes is provided, job standardization can be enhanced productivity and the manufacture method of the metal mold of the cone crushing wall of casting quality or rolled mortar wall casting.
The technical scheme that realizes the object of the invention is: be the manufacture method that is used for the metal mold of broken wall of gyratory crusher manganese steel or rolled mortar wall casting, with in the integrally-built metal mold replacement conventional cast every sand cooling iron.
Described metal mold comprises nearly interior metal mold and nearly outer metal mold, and it is made with metal material, and is close with the natural pattern shape, is arranged on the inside and outside passive member of casting mold; When covering sand, interior nearly metal mold and nearly outer metal mold, natural pattern are assemblied on the mold(ing) board, reserve die cavity, can cover sand.
Be used for the manufacture method of the metal mold of broken wall of gyratory crusher manganese steel or rolled mortar wall casting, comprise the steps:
(1) according to cone crushing wall or the different size specification models of rolled mortar wall, makes natural pattern;
(2) shape according to natural pattern manufactures and designs metal mold and the outer metal mold of nearly shape in the nearly shape corresponding wall thickness, integrally-built respectively;
(3) near metal mold and closely outside lay flaring steam vent respectively on the metal mold wall, promptly get the metal mold of broken wall or rolled mortar wall.
The material of described nearly interior metal mold and nearly outer metal mold can be made with carbon steel, casting pig or spheroidal graphite cast-iron;
Described nearly interior metal mold is identical with the thickness of nearly outer metal mold, and its thickness is different and different with the specification of cone crushing wall or rolled mortar wall, can be 20-65mm;
Steam vent horn mouth subtend on the described metal mold is covered layer of sand, and the quantity of steam vent is 100-150, and the diameter of steam vent is 15-20mm;
Advantage of the present invention is:
1, metal mold and nearly outer metal mold are the overall structure that the natural pattern of shape and prefabricated broken wall or rolled mortar wall mates near, can realize moulding mechanization, and job standardization can be increased work efficiency greatly;
2, adopt inside and outside metal type sand-covering technique, can quicken the cooling velocity in potassium steel primary crystallization stage, the acquisition overcooling austenite is a matrix, and promptly cast(ing) surface obtains fine grain structure under the as cast condition;
3, adopt inside and outside metal mold to have good mold stiffness, the displacement of no type wall;
4, cavity dimension precision height, any surface finish is for fusing, the cast of operation afterwards provides smart type;
5, the dimensional accuracy height of the broken wall of being produced, rolled mortar wall foundry goods, indeformable, surface roughness can reach Ra12.5-Ra25, reduce process cost and labour intensity such as subsequent handling such as peeling, polishing, soldering greatly.

Among the figure: 1. metal type sand-covering layer 5. outer metal type sand-covering layer 6. mold(ing) board 7. steam vent in outer metal mold 3. natural patterns 4. of metal mold 2. nearly shapes in the near shape
The specific embodiment
Broken wall of figure conic crusher manganese steel of the present invention or rolled mortar wall are mantle and fixed secondary wear resistance castingses of boring mutual coupling, using simultaneously in the gyratory crusher, and the broken wall of different size model or the metal mold manufacturing process of rolled mortar wall are identical.
Below to make
The near interior metal mold and the nearly outer metal mold of rolled mortar wall are embodiment, and the invention will be further elaborated in conjunction with the accompanying drawings, only is used for the present invention is illustrated but should understand following embodiment, and is not in order to limit protection scope of the present invention.
Embodiment
Make
The near interior metal mold of rolled mortar wall and the method for nearly outer metal mold comprise the steps:
(1) basis
Cone crushing wall or rolled mortar wall specifications and models are made natural pattern 3;
(2) manufacturing and designing corresponding wall thickness respectively according to the shape of natural pattern 3 is metal mold 1 and the outer metal mold 2 of nearly shape in the integrally-built nearly shape of 65mm, and material is a carbon steel;
(3) outer metal mold 2 150 of the layings of metal mold 1 and nearly shape, diameter are in nearly shape
Flaring steam vent 7.
When covering sand, nearly metal mold 1 and the outer metal mold 2 of nearly shape, natural pattern 3 are assemblied on the mold(ing) board 6 in the shape, reserve die cavity, the back-up sand and the reality of pounding in die cavity then, metal type sand-covering layer 4 and outer metal type sand-covering layer 5 in sclerosis back molding obtains are contained in interior metal type sand-covering layer 4 and outer metal type sand-covering layer 5 on the bottom board, buckle the top box that is provided with rising head, promptly pourable, promptly obtain broken wall or rolled mortar wall after the insulation cooling.
