Abstract
The utility model relates to a casting die of an axially split pump. The casting die comprises positioning columns, a sand core, a core head and a cavity, wherein the sand core adopts a structure of two symmetrical pump dies, and two pump bodies of the sand core share one axially split core head; a water inlet runner and a water outlet runner are respectively of a three-point fix structure, and are used for accurately guaranteeing the mounting position of the sand core. The axially split pump has the beneficial effects that the problems can be solved due to the improvement of the die design and layout, and two pump bodies can be once cast, so that the sand amount can be reduced, the casting efficiency can be improved, the casting material cost and storage field can be saved, and the quality rate of castings can be improved to 100 percent.
Description
Technical field
The utility model belongs to die casting field, relates in particular to a kind of middle-opening pump casting mould.
Background technology
In traditional middle-opening pump sand casting process, conventionally adopt one case die casting mode of, not only sand using amount is large, and casting efficiency is low.Because pump body structure is asymmetric, loam core is opened face and is entered (going out) water core print location and support in need relying on, and the stability in loam core is not good, must increase corresponding loam core stud and lengthen core print, stud easily causes the pump housing after casting to leak because fusion is bad in casting process, and lengthening core print has increased sand using amount.Meanwhile, the position in loam core is difficult for determining, in order to ensure quality, need increase the wall thickness of part, thereby cause casting weight to exceed design weight when mould production, and placer iron mostly is 1:5 to 1:6 than generally, and sand using amount is larger.
In addition, for the medium-sized or above pump housing, need to occupy the larger auxiliary facility such as space storage mould and sandbox, also increase technique circulation requisite space.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of middle-opening pump casting mould, by the improvement to Design of Dies and layout, overcome the above problem, realize two pump housings of disposable casting, not only reduced sand using amount, improve casting efficiency, save molding material cost and storage place, casting qualified rate is increased to 100%.
The purpose of this utility model completes by following technical solution.This middle-opening pump casting mould, comprises locating dowel, core, core print and die cavity, and described core adopts two mould for pump body symmetrical expression layout structures, opens face core print and share in two pump housings of core; Water inlet flow channel and outlet passage are three-point fix structure, for accurately ensureing the installation site of core.
The beneficial effects of the utility model are: compared with prior art, the utility model originally has advantages of that cost is low, work efficiency is high, occupied ground is little, qualification rate is high, is embodied in following three aspects::
One, adopt the symmetrical expression integral layout structure of two of moulds, water inlet flow channel and outlet passage are three-point fix structure, can accurately ensure the installation site of core, can cancel stud, effectively avoid, because of the bad leakage problems causing of stud place fusion, greatly having improved the qualification rate of foundry goods;
Two, the core print of intake-outlet can shorten over half, in open face core print can share, thereby can reduce by 1/4 sand using amount;
Three, because stability and the position degree in loam core are high, can not cause the phenomenon on inclined to one side limit, loam core, mould can strictly be pressed design drawing and produce, and has saved material cost more than 10%;
Four, once can complete the casting of two pump housings, improve 50% casting efficiency, and save because of mould and the accessory space taking that circulates.
Brief description of the drawings
Fig. 1 is the utility model mould schematic diagram;
Fig. 2 is the utility model mould water-in and water-out runner schematic diagram.
Label in accompanying drawing is respectively: locating dowel 1, core 2, core print 3, die cavity 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction:
As shown in Figure 1 to Figure 2, this middle-opening pump casting mould, comprises locating dowel 1, core 2, core print 3 and die cavity 4, and described core 2 adopts two mould for pump body symmetrical expression layout structures, opens face core print and share in two pump housings of core 2; Water inlet flow channel and outlet passage are three-point fix structure, do not need stud, for accurately ensureing the installation site of core 2.Adopt die casting of the present utility model, can disposablely complete the casting of two pump housings.
The utility model is by the improvement to Design of Dies and layout, by traditional one case one make one case symmetrical expression integral layout structure of two into, water-in and water-out runner is three-point fix structure, do not need stud, can accurately ensure the installation site of core, can two pump housings of disposable casting, not only reduce sand using amount, improve casting efficiency, save mold cost and storage place, also improved casting qualified rate.
The utility model is not limited to above-mentioned embodiment; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection domain.
