Abstract
The invention belongs to the technical field of mechanical equipment and discloses a nut casting die. The nut casting die comprises a die body. The die body comprises an upper cavity and a base which are integrally formed. The nut casting die is simple in structure. The appearance of the die is manufactured through the resin sand molding process. Due to the fact that resin sand is high in strength, a cast casting cannot expand in a box, manual grinding operation is avoided, casting cost is saved, the size of the appearance of the casting is controlled within 1.5 mm, the stable size of the casting is guaranteed, the yield is high, the production speed is high, grinding is not needed, labor is saved, and efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of nut casting mould, belong to mechanical equipment technical field.
Background technology
Nut is also nut, be be screwed in bolt or screw rod together be used for the part that plays the role of fastening, be all manufacture machinery must a kind of part, use widely, according to the difference of material, mainly be divided into carbon steel, several large type such as stainless steel and non-ferrous metal, and screw nut die, then be used to the instrument making nut shaping, it realizes the processing of article profile mainly through the change of institute's moulding material physical state, making blank become under external force has given shape and size nut, therefore, the use of screw nut die widely, it is the important apparatus realizing nut production in enormous quantities.
But, along with the use gradually of screw nut die, its some use deficiencies are also constantly manifesting, existing screw nut die in use, external mold die cavity is generally one go out two aluminum dipping forms, hand moulding technique, this die shape intensity caused is low, foundry goods easily rises case after pouring, overall dimensions are difficult to control within 1.5mm, great casting effect and the casting quality affecting foundry goods, therefore, in order to ensure the overall dimensions of foundry goods, need to carry out manual polishing to the overproof part of the case that rises to complete, cause the significant wastage of manpower and materials, and it is few that this mould goes out number, production efficiency is low, waste time and energy very much, the overall economic efficiency causing nut to cast low, for this reason, we propose a kind of nut casting mould.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of nut casting mould, because phenolic sand molding technique does mould external form, resin sand intensity is high, and therefore after casting, foundry goods can not produce the case that rises, and avoids manual polishing to complete, save casting cost, foundry goods overall dimensions control within 1.5mm, and casting dimension is stablized, and it is many to go out number, speed of production is fast, does not need polishing, saves manpower, substantially increase efficiency, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The invention provides a kind of nut casting mould, comprise die ontology, described die ontology comprises upper cavity and base, described upper cavity and base one-body molded.
As a preferred technical solution of the present invention, described die ontology top is provided with groove, and described inside grooves is provided with hexagonal through hole.
As a preferred technical solution of the present invention, described die ontology external form is made by phenolic sand molding technique.
As a preferred technical solution of the present invention, described groove is circular.
The beneficial effect that the present invention reaches is: a kind of nut casting mould, does mould external form by phenolic sand molding technique, because resin sand intensity is high, therefore after casting, foundry goods can not produce the case that rises, and avoids manual polishing to complete, saves manpower, save casting cost, make foundry goods overall dimensions control within 1.5mm simultaneously, ensure the stable of casting dimension, and it is many to go out number, speed of production is fast, substantially increase efficiency, hoisting nut productivity effect, reduce mixed economy cost.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for description, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.
In the accompanying drawings:
Fig. 1 is a kind of nut casting mould top view described in the embodiment of the present invention;
Fig. 2 is a kind of nut casting mould profile described in the embodiment of the present invention;
Fig. 3 is a kind of nut casting mould left view described in the embodiment of the present invention;
Number in the figure: 1, die ontology; 2, groove; 3, hexagonal through hole; 4, upper cavity; 5, base.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment: refer to Fig. 1-3, a kind of nut casting mould of the present invention, comprise die ontology 1, described die ontology 1 comprises upper cavity 4 and base 5, described upper cavity 4 and base 5 one-body molded.
Described die ontology 1 top is provided with groove 2, described groove 2 inside is provided with hexagonal through hole 3, the setting of hexagonal through hole 3, effectively can ensure the external form of cast article, described die ontology 1 external form is made by phenolic sand molding technique, because resin sand intensity is high, therefore after casting, foundry goods can not produce the case that rises, and avoids manual polishing to complete, save manpower, save casting cost, make foundry goods overall dimensions control within 1.5mm simultaneously, ensure the stable of casting dimension, and it is many to go out number, speed of production is fast, substantially increases efficiency, and described groove 2 is circular.
It should be noted that, the present invention is a kind of nut casting mould, during work, die ontology 1 is fixed, cast material is entered hexagonal through hole 3 to cast, by making nut shaping under External Force Acting, in the process, owing to doing mould external form by phenolic sand molding technique, therefore, after casting, foundry goods can not produce the case that rises, manual polishing is avoided to complete, save manpower, save casting cost, make foundry goods overall dimensions control within 1.5mm simultaneously, ensure the stable of casting dimension, and it is many to go out number, speed of production is fast, thus the production efficiency of nut and the quality of production are improved.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
