Abstract
Utility model discloses a kind of epoxy resin mould, and in this epoxy resin mould, be provided with one or several ribs or floor or rib block or ribbed pipe, described rib, floor, rib block, ribbed pipe are rigid body; The structure of this epoxy resin can improve mould machine performance and mechanical property, and make it not yielding, shrinkage factor is low, can use by continous-stable, mould good toughness, is applicable to Digit Control Machine Tool processing, meets the demand of different die modeling.
Description
Technical field
Shaping the used mould of the utility model design on-metallic article, is specially a kind of epoxy resin mould.
Background technology
Utilize Making mold product, must first according to the die cavity designed and produced on mould and mould of mould bases, product.
Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy.The requirement that Design of Dies makes is: size accurately, any surface finish, easy to manufacture, the life-span is high, cost is low.At present, automobile, aviation/space flight, the mould material of shipbuilding industry is generally carbon steel, steel alloy, plastics, epoxy resin mould etc.The density of metal or alloy material is large, and finished product is heavier, not easy to operate, and its thermal coefficient of expansion is large, easily causes precision low, have stress corrosion dehiscence resistant to be inclined to during process operation, after long-time use, easily produces metal fatigue, not corrosion-resistant, affects its service life.Plastic material hardness is little, wears no resistance, the shortcomings such as mutability, does not meet the requirement of precision die.Epoxy resin mould is also known as resin die, and it has, and the manufacturing cycle is short, cost is low, be particularly suitable for complex-shaped goods and model change industrial circle fast.The manufacture characteristic of epoxy resin mould, be that manufacture is simple and easy, fast, cost is low.
Epoxy resin mould, by matrix resin, curing agent, flexibilizer, the composition such as filler and fibre reinforced materials, adopt the words that pouring technology makes: weigh and mixing in Formulaion of epoxy resin ratio, be then poured into mould, by Recipe requirement, adopt room temperature or hot setting shaping, rise a curing reaction make.
But the mechanical performance of epoxy resin mould and mechanical property are desirable not enough, need to be improved further.Its structure causes mould to be easily out of shape, and shrinkage factor is higher, and be difficult to continuously, stablize use, toughness is also not ideal enough, causes adding precise decreasing in man-hour for Digit Control Machine Tool, and the applicability of different die modeling is narrower.
Utility model content
For improving mechanical performance and the mechanical property of epoxy resin further, the utility model discloses a kind of epoxy resin mould containing rib, and its task improves the physical property of epoxy resin mould.The structure of this epoxy resin can improve mould machine performance and mechanical property, and not yielding, shrinkage factor is low, can use by continous-stable, mould good toughness, is applicable to Digit Control Machine Tool processing, meets the demand of different die modeling.
This epoxy resin mould, is characterized in that, in described epoxy resin mould, be provided with one or several ribs or floor or rib block or ribbed pipe, described rib, floor, rib block, ribbed pipe are rigid body.
When mould is subject to the power from mold exterior, power can be delivered to rib, floor, rib block by matrix resin, thus the enhancing that rib, floor, rib block are produced concrete as the reinforcing bar of armored concrete, supporting function, humidification is physically produced to matrix resin.
Preferably, above-mentioned rib, floor, rib block, ribbed pipe are fibre reinforced materials, particularly fibre reinforced composites.
Preferably, the locus of rib, floor, rib block, ribbed pipe is set, to improve or to adjust the physical property of mold integral further in one or more modes following:
Rib or floor or rib block or ribbed pipe quantity are at least two (individual), arbitrary rib, be at least the rib of one (individual) or floor or rib block or ribbed pipe be located in described epoxy resin mould in a staggered manner with other quantity;
Rib or floor or rib block or ribbed pipe and other quantity are at least the rib of one (individual) or floor or rib block or ribbed pipe, in mutually perpendicular mode, are staggeredly located in described epoxy resin mould;
Rib or floor or rib block or ribbed pipe quantity are at least two (individual), and distance is each other 25-50 centimetre;
Establish quantity to be at least rib or the ribbed pipe of two (individual) in epoxy resin mould, its axle is positioned at same plane and is parallel to each other; Again further, if its rib or ribbed pipe not only one deck, the rib between different layers or the axle of ribbed pipe are that projection is intersected, that is: in described rib or ribbed pipe, axle is positioned at conplane rib or ribbed pipe, is positioned at the rib of another plane with other axles, and their axle is that projection is intersected.
The structure of this epoxy resin can improve mould machine performance and mechanical property, and make it not yielding, shrinkage factor is low, can use by continous-stable, mould good toughness, is applicable to Digit Control Machine Tool processing, meets the demand of different die modeling.
accompanying drawing illustrates:
Fig. 1: the perspective view of mould.
Fig. 2: the sectional view of mould.
Wherein, 1 is mould, and 2 is rib, and 3 is ribbed pipe.
detailed description of the invention:
First make the mould of die needed 1, in this example, mould is cuboid; Then three rib 2, three ribbed pipes 3 are fixed in above-mentioned mould; Mould 1 after last moulding by casting, as depicted in figs. 1 and 2.
After moulding by casting is cylinder containing rib epoxy resin mould 1, three ribbed pipe 3, and its axle is parallel, the length 10 of bus doubly with its bottom surface radius.Rib 2 is high relative to long and wide, and the cuboid that long measure is less, is positioned at the top of three ribbed pipes 3, and the distance that three ribbed pipes 3 points are clipped to nearest rib 2 is 30 centimetres.The projection of three ribbed pipes 3 is all in the plane at the common place of three ribs 2, and perpendicular, therefore also meets the requirement that projection is intersected, also meets staggered requirement simultaneously; If there is no rib 2, only have ribbed pipe 3, then do not meet the staggered requirement be located in epoxy resin mould 1.
Rib 2 is this fibre reinforced materials of glass fibre, and floor is carbon fiber, metal fiber composite.
This is used to contain rib epoxy resin mould 1 when making shaped article, time from the defeating on binder resin of a direction, resin can be delivered to rib 2, ribbed pipe 3 power, cause the elastic deformation of rib 2, ribbed pipe 3, and then a reaction force is produced to resin, support whole mould 1, the reinforcing bar in principle and armored concrete is similar, thus improves the physical property of mould 1.
Also floor or rib block can be adopted to substitute ribbed pipe 3 or the rib 2 of one of them or several, and its position can with reference to the mode of above-mentioned ribbed pipe 3 with rib 2.
Above-mentionedly use machining center to process the die cavity on mould 1 containing after rib epoxy resin mould 1 completes, the mould 1 processing die cavity is fixed on mould bases, just can compacted products.Also the above-mentioned rib epoxy resin mould 1 that contains can be utilized to make injection mould, blow molding die, adsorption mould etc.
