Abstract

The utility model discloses a water filter body casting die, which comprises a bottom core and two metal half dies arranged on the bottom core. Peripheries of the two half dies are jointed and form a closed water filter body casting cavity with the bottom core, a sealing cap is arranged at an opening of the casting cavity, a casting hole and exhaust holes which are communicated with the casting cavity are formed at two ends of the sealing cap respectively, a connecting through hole penetrating through a positioning pin is arranged at the joint of two sides of the two half dies, the casting hole is arranged on one side of the water filter body casting die, the lower portion of the casting hole is disposed in the exhaust hole on the same side with the casting hole. By adopting the above technical scheme, the water filter body casting die has the advantages of low environmental pollution and high accuracy of cast parts as compared with casting of sand dies.

Description

A kind of water filter body casting mould

Technical field

The utility model relates to a kind of water filter body casting mould.

Background technology

The general sand mo(u)ld that adopts of prior art casting is made mold; Sand casting need be put into the fabricated part model in molding sand; Around model, fill up molding sand then, thereby form mold, before the cast aluminum alloys liquation; Must take out model; Then the sand mold mould must be made two or more parts, the sand mold mould is made amendment again, and makes it have the hole of casting liquation in the sand mold mould; The casting back keeps appropriate time; Solidification of molten metal is processed cast, and taking-up cast then sand mold mould is ruined, and therefore is necessary for each cast member analogue formation; To the operator and Yan Yaoyou technological accumulation for many years; This forging type sand mold mould can't be reused, contaminated environment simultaneously, and defectives such as foundry goods exists that precision is low, rough surface and poor mechanical property.

The utility model content

The utility model technical problem to be solved provides a kind of environmental pollution and high water filter body casting mould of foundry goods precision of reducing.

For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of water filter body casting mould that is provided; Comprise end core and metal mold two-half die placed on it; Described two-half die periphery forms the water filter body casting die cavity of sealing and tapping hole and the steam vent that communicates with the casting die cavity with end core, and the oral area of casting die cavity is provided with seal cover, and the oral area of tapping hole and steam vent places the seal cover two ends respectively; The both sides joint of described two-half die also is provided with the connecting through hole that passes alignment pin.

Described tapping hole places mould one side, and its bottom communicates with the steam vent of its homonymy.

Described steam vent is symmetricly set on the both sides of mould respectively.

Described steam vent is the bigger flask shape of belly, and the part that stretches into the casting die cavity is about 90 ° of settings with oral area.

Described two-half die casting die cavity two ends joint up and down also is provided with ventilating groove.

Ventilating groove is many, is distributed on the joint of two ends up and down of two-half die.

The bottom of described two-half die casting die cavity also is provided with a plurality of ventilative apertures that communicate with it.

Adopt the technical scheme of the utility model, can cast by a type more, save Modeling Material; This forging type is compared with sand casting, and mould need not on-the-spot heap sand, has reduced the pollution to environment; Cast molding is cast to molten aluminium alloy and obtains foundry goods in the metal mold cavity, and the operator need not the experience accumulation through for many years, and technology is simple, is easy to realize mechanization; The foundry goods of cast molding is compared the precision height with the foundry goods of sand mold molding, surface roughness value is little, mechanical property good; Be applicable in batch, a large amount of production; Steam vent is the bigger flask shape of belly, and tapping hole stretches into the belly of steam vent, can cushion the molten aluminium alloy of pouring into wherein, avoids liquation to spill causing burning; The setting of ventilating groove and ventilative aperture, the cooling velocity of quickening liquation shortens molding time, improves the operating efficiency of casting.

Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.

Description of drawings

The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure briefly explains:

Fig. 1 is a kind of water filter body casting of the utility model mold structure sketch map;
