Utility model content
The purpose of this utility model is to provide a kind of without fash valve body moulding, to solve proposition in above-mentioned background technology
Problem, is had the beneficial effect that by the splicing of main core makes into main core global formation, then by 10 little core splicings
Main core, stitching portion, loam core uses high-strength novel binding agent, it is ensured that will not rupture when molten iron enters die cavity in stitching portion, with
Time also solve the problem of batch seam in main core runner, by arranging a sprue gate, and lead to die cavity by horizontal run, subtract
Lack the consumption of molten iron and rising head, save production cost.
For achieving the above object, this utility model provides following technical scheme: a kind of without fash valve body moulding, including cast
Mouth, foundry goods body, core, the first horizontal run and vertical run, one end of described foundry goods body upper surface is provided with sprue gate, waters
Geat connects with the vertical run of foundry goods body interior, and described vertical run is by the 3rd auxiliary flow of middle position and the
One end of one horizontal run connects, and the first horizontal run runs through the upper end of foundry goods body interior core, described first level stream
The other end in road is connected by AC port and the second horizontal run, and the second horizontal run runs through the bottom of core, described core
Being provided with uniform reinforcement, the side of described foundry goods body is provided with ten and is provided with air-vent between sand-spraying hole, and sand-spraying hole.
Preferably, chill height exothermic riser it is provided with at described sprue gate.
Preferably, described core has ten, and is divided into two row to be arranged symmetrically in the inside of foundry goods body.
Preferably, described AC port is connected with the core of AC port side by the first auxiliary flow.
Preferably, the bottom of described vertical run is connected with the core of vertical run side by the second auxiliary flow.
Compared with prior art, the beneficial effects of the utility model are: this equipment is by making the splicing of main core into main sand
Core global formation, then spliced main core by 10 little cores, stitching portion, loam core uses high-strength novel binding agent, it is ensured that splicing
It is in when molten iron enters die cavity and will not rupture, also solve batch problem stitched in main core runner simultaneously, water by arranging one
Geat, and lead to die cavity by horizontal run, decrease the consumption of molten iron and rising head, save production cost.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model provides: a kind of without fash valve body moulding, including sprue gate
1, foundry goods body 2, core the 3, first horizontal run 7 and vertical run 13, one end of foundry goods body 2 upper surface is provided with sprue gate 1,
Being provided with chill height exothermic riser at sprue gate 1, sprue gate 1 connects with the vertical run 13 within foundry goods body 2, vertical run 13
Bottom connected with the core 3 of vertical run 13 side by the second auxiliary flow 8, vertical run 13 passes through middle position
3rd auxiliary flow 9 connects with one end of the first horizontal run 7, and the first horizontal run 7 runs through foundry goods body 2 internal cores 3
