In the application process of reality because the defective of Design of Dies, so that the shaped article surface easily appears in this mould in actual batch production process bubble, out-of-flatness are arranged, reduce the yield rate of product, owing to being to occur in batch production process, this will cause larger waste of raw materials.
Moreover, owing to the shape of the forming hole on the plastics suction mould and the mode problem of distribution, cause the problem of the mould inconvenience demoulding, the large efficient of producing in enormous quantities, this will cause great economic loss to enterprise.
The utility model content
The utility model occurs the problems such as waste of raw materials and production efficiency is low when the plastics sucking moulding for existing plastics suction mould, and a kind of energy-saving sandblast mould is provided.This mould improves the yield rate of product greatly by structural improvement, effectively reduces raw-material waste, thereby reduces its production cost.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of energy-saving sandblast mould, it comprises an aluminium-making mould body, and described mold is that a cross section is oval-shaped Elliptic Cylinder, offers three forming holes on the surface of mold, and described three forming holes are symmetrical along the curved edge on mold surface.
In preferred embodiment of the present utility model, a forming hole distributes along mold centre of surface axis in described three forming holes, and two forming holes are symmetrically distributed in its both sides in addition.
Further, arc transition between the sidewall of described forming hole and the bottom.
Further, the bottom of described forming hole is distributed with some projections.
Further, the array distribution of even distance between described some projections.
Further, the spacing between the described projection is 4-5mm.
Further, described projection is that the length of side is the 2-3mm bumping square, and the height of described projection is 1-2mm.
Further, the surface of described mold arranges one deck sandblast layer.
The utlity model has following advantage according to what such scheme obtained:
(1) adopts the mould of Elliptic Cylinder, be provided with three forming holes thereon simultaneously, and distribute with special distribution mode, yield rate that can the Effective Raise product;
(2) the excessive part at forming hole adopts the circular arc setting, can be convenient to the demoulding of product;
(3) be distributed with corresponding projection in the bottom of forming hole, can not be convenient to the demoulding, when plastic uptake is produced, can improve the quality of shaped article bottom simultaneously.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the energy-saving sandblast mould 100 that the utility model provides, it mainly comprises a mold 101.This mold 101 adopts aluminum, to improve durability, energy saving, production efficiency and the rate of reducing the number of rejects and seconds of mould.
For the drop-shaped product, because the side of this product all is to be made of continuous arc, thus very difficult when utilizing plastics suction mould to carry out plastics sucking moulding, be difficult to form even thickness, side wall strength meets the requirements of product.
For this reason, it is oval-shaped Elliptic Cylinder that the mold 101 that the utility model provides adopts cross section, and offer three forming holes 102 at the working face 101a of mold 101, these three forming holes 102 are drops, and symmetrical along the curved edge 101b on the concrete surface of elliptical mode.
It is elliptical mode concrete 101 that the utility model adopts the cross section, simultaneously on this mold 101 to the forming hole 102 that is provided with three water-drop-shapeds, adopt special distribution mode on oval-shaped surface like this, so that match with the shape of forming hole 102 in the mold surface, distribute spacing is reasonable between three forming holes 102, is convenient to the moulding of finished product.When plastics sucking moulding, can allow raw material be uniformly distributed on forming hole 102 surfaces, form even thickness, the consistent product of side wall strength.
Further, in order to reach the maximum utilization of mold, three forming hole 102 area occupied are 3/4 of the mold 101 working face 101a gross areas, are guaranteeing under the prerequisite of properties of product like this, so that the materials of mold drop to is minimum, effectively reduce production costs.
On the basis of such scheme, the utility model also provides further prioritization scheme, to improve the performance of mould, so that the ratio of briquetting of product improves and materials reduce.
In prioritization scheme, in three forming holes 102, the first forming hole 102a distributes along longitudinal center's axis (being than minor axis on the oval face) of mold working face 101a, and the central axis of the first forming hole 102a overlaps with longitudinal center's axis of mold working face 101a, the bottom of the first forming hole 102a is positioned at the edge of mold working face 101a simultaneously, all the other two the second forming hole 102b adopt the distribution arrangement consistent with the first forming hole 102a with the 3rd forming hole 102c, and be symmetrically distributed in the both sides of the first forming hole 102a, and be 60 ° angle between the central axis of the central axis of two forming hole 102b and 102c and the first forming hole 102a.
By this prioritization scheme, so that cooperating between the forming hole and between forming hole and the mold working face reaches the most appropriate design, can greatly improve the ratio of briquetting of product.Moreover because the raw material consumption that above-mentioned optimal design can reduce greatly, thereby can reduce by 20% production cost.
The utility model also provides another prioritization scheme, with the demoulding efficiency of raising mould and the quality of product.
As shown in the figure, the utility model adopts arc transition 102d between the sidewall of forming hole 102 and bottom, not only can be convenient to like this moulding of product, can also be convenient to the demoulding of product simultaneously, to increase work efficiency.
Moreover the utility model is provided with some projection 102e in the bottom of forming hole 102, and these projections 102e spares the array distribution of distance along forming hole 102 bottom shapes.
Further, the spacing between these projections is 4-5mm, and projection is that the length of side is the 2-3mm bumping square simultaneously, and the height of projection is 1-2mm.
In this prioritization scheme, the effect by projection 102e is adopted the projection of above-mentioned size and dimension simultaneously so that product very convenient demoulding after moulding, can improve the adhesion of raw material and mould when plastics sucking moulding, effectively guarantees the quality of product bottom moulding.By this scheme, the utility model can improve the demoulding efficiency of product, thereby can improve 30% production efficiency.
In another prioritization scheme, the utility model (comprises in the forming hole) on the surface of mold one deck sandblast layer is set, make mould when moulding the surface air to around diffusion, the surfacing of product is difficult for that bubble is arranged.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
