Abstract
The invention relates to a mold for thin-wall parts and large-cavity parts. The mold comprises a die casting mold body, and is characterized in that a mold frame is arranged at the periphery of the die casting mold body and is provided with auxiliary pressure point parts. Therefore, due to the auxiliary pressure point parts, full contact surfaces between the die casting mold body and parts can be effectively ensured, and the die casting quality of the die casting mold body in actual production is improved. According to the requirement for manufacturing the thin-wall parts and the large-cavity parts particularly, an area in which the auxiliary pressure point parts are distributed is a non-structure molding surface of the die casting mold body, the integrity of die casting is realized, the die casting quality cannot be influenced, and the mold deserves promotion and application.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of thin-wall part and big cavity spare is used mould.
Background technology
With regard to prior art, mould is to be used for the instrument of formed article, and this instrument has various parts to constitute, and different dies is made up of different parts.It mainly realizes the processing of article profile through the change of institute's moulding material physical state.Press the difference of the material of institute's moulding, mould can be divided into metal die and nonmetal mould.Metal die is divided into again: casting mould (non-ferrous metal die casting, steel casting) and forging mold etc.; Nonmetal mould also is divided into: mould of plastics and inorganic non-metallic mould.And according to the difference of the material of mould own, mould can be divided into: sand mold mould, metal die, vacuum mold, paraffin mould or the like.Wherein, along with the fast development of high molecule plastic, mould of plastics and people's life is closely related.Mould of plastics generally can be divided into: injecting molding die, extrusion moulding mould, gas assisted molding mould or the like.Mould structure design and parameter are selected to consider factors such as rigidity, guidance quality, shedding mechanism, localization method, gap length.Consumable accessory on the mould should be changed easily.For plastics mould and compression mod, also need consider rational running gate system, molten plastic or metal flow state, the position and the direction that get into die cavity.In order to boost productivity, reduce runner cast loss, can adopt the multi-imprssion mould tool, in a mould, can accomplish a plurality of identical or different goods simultaneously.In production in enormous quantities, should adopt the mould of high efficiency, high accuracy, high life.
But; In the existing mould manufacturing field; Particularly to thin-wall part and big cavity spare with mould because it lacks necessary contact component with other equipment of mould, and can't satisfy between pressurize casting mould body and each parts has sufficient contact-making surface, the acceptance rate of product after casting.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, provide a kind of thin-wall part and big cavity spare to use mould.
For realizing that a kind of thin-wall part of the object of the invention and big cavity spare use mould, include the die casting body, it is characterized in that: described die casting body periphery is provided with the mould framework, is distributed with on the described mould framework to assist the pressure point parts.
Further, above-mentioned a kind of thin-wall part and big cavity spare are used mould, and wherein, described auxiliary pressure point component distribution is in the outside of mould framework.
Further, above-mentioned a kind of thin-wall part and big cavity spare are used mould, and wherein, the thickness of said auxiliary pressure point parts is 3～6 millimeters.
Further, above-mentioned a kind of thin-wall part and big cavity spare are used mould, and wherein, the thickness of said auxiliary pressure point parts is 4 millimeters.
Again further, above-mentioned a kind of thin-wall part and big cavity spare are used mould, and wherein, described auxiliary pressure point parts are columned pressure point post, or are cone shape pressure point post, or are the pressure point post of cubic.
Adopt technical scheme of the present invention, through the existence of auxiliary pressure point parts, can effectively guarantee has sufficient contact-making surface between die casting body and each parts, has promoted the die casting quality in the actual production of die casting body.Particularly be directed against the manufacturing demand of thin-wall part and big cavity spare; The zone of the auxiliary pressure point component distribution that the present invention adopts is the non-structure formation face of die casting body; Both realized the integrality of die casting, and can not influence the quality of die casting again, and be worth applying in the art.
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is that this thin-wall part reaches the organigram of big cavity spare with mould.
The implication of each Reference numeral is following among the figure:
1 die casting body, 2 mould frameworks
3 auxiliary pressure point parts
The specific embodiment
A kind of thin-wall part and big cavity spare as shown in Figure 1 are used mould, include die casting body 1, and its unusual being: the periphery of the die casting body 1 that the present invention adopted is provided with mould framework 2.And, on mould framework 2, be distributed with auxiliary pressure point parts 3.Like this, can realize effectively that the zone that auxiliary pressure point parts 3 distribute is the non-structure formation face of die casting body 1, can not cause unnecessary influence follow-up casting manufacturing.
In conjunction with the present invention's one preferred implementation; For the ease of saving the pressing mold and the demould time of die casting body 1; And can adopt the auxiliary pressure point parts 3 of minimum number to satisfy actual manufacturing needs, the auxiliary pressure point parts 3 that the present invention used are distributed in the outside of mould framework 2.
Further, consider and improve the support that auxiliary 3 pairs of die casting bodies of pressure point parts 1 combine tightness degree that the thickness of auxiliary pressure point parts 3 is 3～6 millimeters.And, through finding after the multiple comparison test that the thickness of auxiliary pressure point parts 3 is 4 millimeters, can play preferable effect.
Again further; Consider in the actual manufacture process thin-wall part or big cavity spare foundry goods has different casting demands; Profile structure to auxiliary pressure point also has different demands; The auxiliary pressure point parts 3 that the present invention adopted are columned pressure point post, or are cone shape pressure point post, or are the pressure point post of cubic.Thus, the matching requirements of various Casting Equipments can effectively adapt to the processing intensive of die casting body 1 and other manufacture component, guarantee the qualification rate of casting.And the auxiliary pressure point parts 3 of employing have four at least, are distributed in the both sides of mould framework 2 in twos.
Through above-mentioned character express and combine accompanying drawing to find out; After adopting the present invention; Through the existence of auxiliary pressure point parts, can effectively guarantee has sufficient contact-making surface between die casting body and each parts, has promoted the die casting quality in the actual production of die casting body.Particularly be directed against the manufacturing demand of thin-wall part and big cavity spare; The zone of the auxiliary pressure point component distribution that the present invention adopts is the non-structure formation face of die casting body; Both realized the integrality of die casting, and can not influence the quality of die casting again, and be worth applying in the art.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
