The utility model relates to a hydraulic turbine sleeve casting mold combination box, which includes a sand box, sand molds are evenly arranged inside the sand box, castings are arranged in the sand box, and an annular riser is arranged on the upper end of the casting, and the gap between the riser and the upper end of the sand box is There is an air outlet between them, and a sand core is provided through the air outlet, the riser, and the casting. The upper end of the sand core is placed outside the sand box, and the lower end of the sand core passes through the casting and is placed inside the sand box. The lower end of the sand core is provided with a transverse gate, the first inner gate is provided between the gate and the lower part of the casting, one end of the gate is provided with a vertical sprue, and the sprue The upper end of the sprue cup is connected with a sprue cup, the sprue cup is set through the sand box, the upper end of the sprue cup is placed outside the sand box, and a plurality of second ingates placed obliquely between the outer wall of the casting and the sprue. The utility model has the advantages of reasonable structure, convenient modeling and ensuring no casting defects on the inner circle processing surface of the sleeve.
Description
Technical field:
The utility model relates to the mould assembling and closing of a kind of hydraulic turbine sleeve.
Background technology:
Sleeve belongs to long tube class foundry goods, higher to processing back fineness and dimension precision requirement, therefore foundry goods can not have shrinkage cavity, shrinkage porosite and crackle, traditional hydraulic turbine sleeve mould assembling and closing structure is too simple, molten iron flows not steady, the core exhaust is obstructed, and foundry goods easily produces slag inclusion, burning into sand, sand holes and gas hole defect.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, provide a kind of rational in infrastructure, be convenient to moulding, guarantee that circle machined surface in the sleeve does not have the hydraulic turbine sleeve mould assembling and closing of casting flaw.
The purpose of this utility model is achieved through the following technical solutions: the mould assembling and closing of a kind of hydraulic turbine sleeve, comprise sandbox, sandbox inside evenly is provided with sand mold, be provided with foundry goods in the sandbox, the upper end of foundry goods is provided with feed-ring, be provided with a venthole between the upper end of rising head and sandbox, run through venthole, rising head, foundry goods is provided with core, the upper end of core places outside the sandbox, the lower end of core is passed foundry goods and is placed the inside of sandbox, and core inside is provided with the core pipe, and the lower end of core is provided with the runner gate of horizontal placement, be provided with first ingate between the bottom of runner gate and foundry goods, one end of runner gate is provided with the down gate of vertical placement, and the upper end of down gate is connected with cup, and cup runs through the sandbox setting, the upper end of cup places the outside of sandbox, is provided with tilted-putted a plurality of second ingate between the outer wall of foundry goods and the down gate.
The utility model compared with prior art has the following advantages:
It is rational in infrastructure, be convenient to moulding, guarantee that the circle machined surface does not have casting flaw in the sleeve, and molten iron disperses to introduce, and reduces foundry goods and core hot-spot.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: 1-sandbox, 2-foundry goods, 3-rising head, 4-venthole, 5-core, 6-core pipe, 7-runner gate, 8-first ingate, 9-down gate, 10-cup, 11-second ingate, 12-sand mold.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of embodiment of the utility model hydraulic turbine sleeve mould assembling and closing as Fig. 1, comprise sandbox 1, sandbox 1 inside evenly is provided with sand mold 5, be provided with foundry goods 2 in the sandbox 1, the upper end of foundry goods 2 is provided with feed-ring 3, be provided with a venthole 4 between the upper end of rising head 3 and sandbox 1, run through venthole 4, rising head 3, foundry goods 2 is provided with core 5, the upper end of core 5 places outside the sandbox 1, the lower end of core 5 is passed foundry goods 2 and is placed the inside of sandbox 1, core 5 inside are provided with core pipe 6, the lower end of core 5 is provided with the runner gate 7 of horizontal placement, be provided with first ingate 8 between the bottom of runner gate 7 and foundry goods 2, one end of runner gate 7 is provided with the down gate 9 of vertical placement, and the upper end of down gate 9 is connected with cup 10, and cup 10 runs through sandbox 1 and is provided with, the upper end of cup 10 places the outside of sandbox 1, is provided with tilted-putted a plurality of second ingate 11 between the outer wall of foundry goods 2 and the down gate 9.
Rising head 3 adopts feed-ring, neither increases the contact thermal center, helps again entering rising head 3 with sand, the slag of molten iron come-up.
The core fire of choking is avoided in sand washing when preventing casting mold when upset drop and cast, and sand mold 12, core 5 should have higher dry consistency and air permeability and good.
Do not have casting flaw in order to ensure circle machined surface in the sleeve, be convenient to moulding, mould assembling operation simultaneously, casting technique adopts divides the mould somatotype along the foundry goods axis, horizontal moulding, and with 90 ° of casting mold upsets, stand up position is poured into a mould after the mould assembling.The utlity model has rational in infrastructure, be convenient to moulding, guarantee that circle machined surface in the sleeve does not have the advantage of casting flaw.
