A manufacturing process of the spiral rotor mould comprises the steps: molding an external mould, covering the external mould by sand, removing the sand, carrying out mould assembling and pouring; the spiral rotor mould is low in manufacturing cost and the production efficiency can be improved.
Description
[technical field]
The utility model relates to a kind of mould, especially a kind of casting sand mo(u)ld of helical rotor.
[background technology]
In the mould of existing helical rotor, spiral and axle head are separated from each other, the die cavity corresponding with the helical rotor outline is set on the iron case, lay the core of helical rotor after the attached sand in iron case top layer at the corresponding position of spiral, concrete technological process comprises the following steps: at first external mold is carried out moulding and manufactures core, then cover sand and lay core in external mold, afterwards die surface being carried out to sand removal, then carrying out mould assembling and build; Moulding helical rotor after building takes out from external mold together with core, then rotates profiled member is separated with sand mold; Relate to core in this preparation method, so cost of manufacture is high.And manufacturing process is more, cause the consuming time longer of manufacturing process, affect working (machining) efficiency.
[summary of the invention]
The technical problem that the utility model solves is to provide a kind of helical rotor mould, and this helical rotor mould, by the improvement of structure, has been given up original core, has saved human resources and manufacturing cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of helical rotor mould, comprise swage, lower swage, and described upper swage and lower swage opposite face are provided with die cavity, and described die cavity comprises the thread segment corresponding with helical rotor and smooth section, and the surface of described die cavity is provided with layer of sand.
Further, described thread segment comprises spiral convex rib, and the two ends of described spiral convex rib are provided with damaged section.
Further, on described upper swage and lower swage, two die cavities are set, described upper swage is provided with the sprue of cast use, described sprue is between two die cavities, the two ends that the opposite face of described lower swage two die cavities is provided with cast gate and described thread segment all arrange described cast gate, are connected with the runner corresponding with sprue on cast gate.
Further, the thickness of described layer of sand is 5mm.
The beneficial effects of the utility model:
In helical rotor mould of the present utility model, the die cavity of upper swage and lower swage comprises the thread segment corresponding with helical rotor and smooth section, divide by the spiral section of moulding helical rotor and two ends optical axis section, after covering sand, the die cavity top layer just can be built, the prototype structure that this structure is compared in background technology is simpler, do not relate to core, therefore can save manufacturing cost, and integrative-structure to compare core more firm, will grow service life.
These characteristics of the present utility model and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
The top view that Fig. 1 is lower swage in the utility model;
The upward view that Fig. 2 is upper swage in the utility model.
[specific embodiment]
The utility model provides a kind of helical rotor mould, comprises swage, lower swage, and upper swage and lower swage opposite face are provided with die cavity, and die cavity comprises the thread segment corresponding with helical rotor and smooth section, and the surface of die cavity is provided with layer of sand.Manufacturing process of the present utility model comprises outer modeling, then covers sand, and after sand removal, mould assembling is built; Compare the processing technology in background technology, the utility model has saved the step of manufacturing core and laying core, and the even thickness of layer of sand, can avoid the heat radiation inequality caused because of core, not only can save cost and raise the efficiency, and can improve the quality of product.
Technical scheme below in conjunction with the accompanying drawing of the utility model embodiment to the utility model embodiment is explained and illustrated, but following embodiment is only preferred embodiment of the present utility model, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
With reference to figure 1 and Fig. 2, shown helical rotor mould, comprise swage 2, lower swage 1, upper swage 2 and lower swage 1 opposite face are provided with die cavity, this die cavity comprises the smooth section 32 of the thread segment corresponding with helical rotor 31 and both sides, the die cavity of upper swage 2 and lower swage 1 is one side of something of corresponding helical rotor respectively, and at the layer of sand fitted with die cavity that is covered with of the surface uniform of die cavity.This mould structure is simple, and core has been broken away from the moulding of rotor helical-screw, cost-saved, and the direct withdrawing pattern of profiled member, compares original rotation withdrawing pattern, and production efficiency improves.
Improved, thread segment 31 comprises the spiral convex rib corresponding with helical rotor 33, form the spire of helical rotor between two spiral convex ribs 33, the spiral angle of helical rotor is excessive may cause directly withdrawing pattern of helical rotor after moulding, therefore to the rested and reorganized damaged section of forming section shortage of the two ends of spiral convex rib 33, dodge profiled member with this, allow its direct withdrawing pattern.
Preferably, two helical rotors of helical rotor mould of the present utility model one-shot forming, be provided with two die cavities side by side on upper swage 2 and lower swage 2, upper swage 2 is provided with the sprue 41 of cast use, sprue 41 is between two die cavities, sprue 41 also comprises the wing passage 42 extended to both sides, and the two ends that are equipped with cast gate 43 and thread segment 31 in lower swage 1 on the opposite face of two die cavities are provided with this cast gate 43, are connected with the runner corresponding with sprue 42 on cast gate 43.After mould assembling, the fluid of sprue 41 43 enters die cavity along runner 42 from cast gate.Because the length of rotor is longer, therefore select the suitable mode of building can guarantee the quality of moulding, after adopting this casting system, build runner and be divided into two-way inflow die cavity, and cast gate is positioned at the two ends of thread segment, compares originally and only at middle part, cast gate is set, the profiled member qualification rate of this mould is higher.
In addition, the sand layer thickness adhered on die cavity is 5mm, and this size, under the condition of guaranteeing layer of sand intensity, drops to minimum by the thickness of layer of sand as far as possible, and the profiled member of having built can be cooling fast, improves the efficiency of producing.
By above-described embodiment, the purpose of this utility model is by fully effective having reached.The personage who is familiar with this technology should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top specific embodiment.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
