Abstract
The utility model discloses a metal mould for casting a worm gear and a gear. The metal mould for casting the worm gear and the gear comprises an upper mould plate, a locating ring, an outer mould circle, a middle mould plate and a bottom mould plate. The periphery of the locating ring is provided with a protrusion, the upper end of the locating ring and the lower end of the locating ring is respectively arranged on the upper mould plate and the middle mould plate in inserted mode. The upper mould plate is connected with the lower mould plate by a plurality of arc-shaped shafts, the middle mould plate is fixed on the end mould plate, and the outer mould circle is arranged on the periphery of the upper mould plate, the locating ring and the middle mould plate in sleeved mode and fixed on the end mould plate. The metal mould for the casting worm gear and the gear has the advantages of being reasonable in structure, changing sand casting mode of the prior art by adopting the metal mould to cast, being free from repeat modeling, avoiding rehandling, improving production efficiency, reducing production cost, being high in casting precision, reducing working allowance, being smooth in casting surface, high in casting density, higher than sand casting in intensity, and worth popularizing and applying.
Description
Technical field
The utility model relates to mould, particularly a kind of casting worm gear, gear metal pattern.
Background technology
In the prior art, when casting, usually traditional handicraft is sand casting, and such forging type often needs to carry out first the sand mo(u)ld moulding, and every casting once just needs to repeat the sand mo(u)ld moulding again, causes the continuous duplication of labour.And casting product product allowance out is large, and size is nonstandard, and percent defective is high,, wasted raw material, this traditional forging type production efficiency is low, and production cost is high, is difficult to satisfy Production requirement.
The utility model content
The purpose of this utility model is, for the problems referred to above, provides a kind of casting worm gear reasonable in design, gear metal pattern.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of casting worm gear, gear metal pattern, it comprises cope match-plate pattern, centring ring, outer die ring, middle template and end template, the periphery of this centring ring is provided with projection, plant respectively on this cope match-plate pattern, the middle template in the upper end of this centring ring, lower end, be connected with some Arc Axials between this cope match-plate pattern and the middle template, should middle template be fixed on this end template, described outer die ring is sheathed on the periphery of this cope match-plate pattern, centring ring and middle template and is fixed on this end template.
Be respectively equipped with the through hole of equal number on described cope match-plate pattern, the middle template, namely attractive in appearance after foundry goods forms, improve again and bear the intensity of pressure, save again raw material.The corresponding described through hole of described some Arc Axials is connected between this cope match-plate pattern and the middle template.
The quantity of described Arc Axial is six.
Described cope match-plate pattern, middle template are provided with centre bore, and upper surface of template is provided with the first depression that matches with described centring ring lower end in this, and lower surface of template is provided with the projection of the downward protrusion that matches with the upper surface of described end template in this.
The middle part of described end template upper surface is provided with the second depression that matches with described projection, and the periphery place of this end template upper surface is provided with three depression corresponding with described outer die ring.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, adopts metal pattern to cast, and changes in the past sand casting mode, need not the repetition moulding, avoid the duplication of labour, improved production efficiency, reduced production cost, and casting casting accuracy out is high, can dwindle allowance, cast(ing) surface is level and smooth, and density is high, the strength ratio sand casting is high, is worthy of popularization.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment: see Fig. 1, a kind of casting worm gear of the utility model, gear metal pattern, it comprises cope match-plate pattern 1, centring ring 2, outer die ring 3, middle template 4 and end template 5, the periphery of this centring ring 2 is provided with projection 21, plant respectively on this cope match-plate pattern 1, the middle template 4 in the upper end of this centring ring 2, lower end, be connected with some Arc Axials 6 between this cope match-plate pattern 1 and the middle template 4, should middle template 4 be fixed on this end template 5, described outer die ring 3 is sheathed on the periphery of this cope match-plate pattern 1, centring ring 2 and middle template 4 and is fixed on this end template 5.
Be respectively equipped with the through hole 7 of equal number on described cope match-plate pattern 1, the middle template 4, described some Arc Axial 6 corresponding described through holes 7 are connected between this cope match-plate pattern 1 and the middle template 4.
The quantity of described Arc Axial 6 is six.
Described cope match-plate pattern 1, middle template 4 are provided with centre bore, and upper surface of template 4 is provided with the first depression 41 that matches with described centring ring 2 lower ends in this, and lower surface of template 4 is provided with the projection 42 of the downward protrusion that matches with the upper surface of described end template 5 in this.
The middle part of described end template 5 upper surfaces is provided with the second depression 51 that matches with described projection 42, and the periphery place of these end template 5 upper surfaces is provided with three depression 52 corresponding with described outer die ring 3.。
The utility model is rational in infrastructure, adopts metal pattern to cast, and changes in the past sand casting mode, need not the repetition moulding, avoid the duplication of labour, improved production efficiency, reduced production cost, and casting casting accuracy out is high, can dwindle allowance, cast(ing) surface is smooth, and density of material is high, the strength ratio sand casting is high, is worthy of popularization.
As described in the utility model embodiment, with Castingother worm gear, the gear metal pattern of the same or similar structure of the utility model, all in the utility model protection domain.
