Description
Technical field
The utility model relates to a kind of cast steel technology, refers to a kind of sand cores of castings especially and makes shell mould.
Background technology
Core in casting mold major part surround by the liquid metal of high temperature, and the size of supporting and location part is general less, and therefore core sand is except should having the performance of general molding sand, also requires higher intensity, gas permeability, deformability and collapsibility.Core sand is divided into clay core sand, waterglass core sand, wick sand by binding agent difference used, closes fat core sand, resin core sand etc.
Domestic patent database also discloses the correlation technique of some cores, core preparation method and mould thereof:
Such as: the manufacture method of [title] core mold, core and core, [application number] CN201410028458.8, [applying date] 2014.01.21, discloses a kind of precoated sand multi-stack casting process: core mold comprises: fixed half and moving half, and dynamic model and cover half close up rear formation die cavity; Die cavity comprises: multiplely take turns raia, centring ring chamber, multiple compensated cavity, boss chamber and water oral cavity, multiple one end of taking turns raia is all connected with centring ring chamber, the other end by boss chamber with water oral cavity and be connected, and multiple raia of taking turns is distributed on centring ring chamber and waters between oral cavity, compensated cavity between adjacent wheels raia, and respectively with centring ring chamber with water oral cavity and be connected.The compensated cavity arranged in the core mold that the utility model provides adds the quantity of watering passage between oral cavity and centring ring chamber, precoated sand is enable to be full of die cavity in the short period of time, meanwhile, make the precoated sand in centring ring chamber fill type more abundant, thus improve the qualification rate of product.
Such as: [title] a kind of core, [application number] CN201320848941.1, [applying date] 2013.12.20, disclose a kind of precoated sand multi-stack casting process: comprise core body, described core body comprises core top and core bottom, described core top and described core bottom are connected by contract mouth, the upper inner chamber be interconnected and lower inner cavity is provided with in described core body, described upper inner chamber is positioned at described core top, described lower inner cavity is positioned at described core bottom, the described upper inner chamber be interconnected forms the inner chamber of core body together with lower inner cavity.The beneficial effects of the utility model are: core body interior arranges cavity, alleviate the weight of core, decrease the quantity of material of core, thus reduce the manufacturing cost of core, and are convenient to operative, enhance productivity, and increase core venting quality.
Such as: [title] precoated sand multi-stack casting process, [application number] 201010242422. 1, [applying date] 2010.08.02, disclose a kind of precoated sand multi-stack casting process: after foundry goods drawing making precoated sand core unit, the described core unit of at least two covers is stacked vertically on pouring platform, covers grouting plate and clamp with Connection Element; Then from the liquid material of the cup cast high temperature of grouting plate, the liquid material of high temperature fills foundry goods die cavity, cross gate and sprue under gravity; After the liquid material of high temperature solidifies cooling, obtain foundry goods.The utility model technique, under the prerequisite guaranteeing casting quality, greatly improves casting technique production efficiency, reduces production cost.
Be not difficult to find, existing core only has a die cavity, and die cavity ensconces sand core internal, and cavity shape is identical with cast shape.Because die cavity is closed, the necessary individual cast of two parts up and down of core die cavity, therefore often producing a kind of foundry goods then needs two covers to make shell mould, and cost of manufacture and operation easier are all higher.Be necessary to design the core that makes new advances and make shell mould, improving efficiency and the quality of casting pouring process on the one hand, reduce cost of manufacture and the operation easier of core on the other hand.
