Abstract
The utility model relates to a filling valve foundry goods mould, set up the psammitolite in upper and lower shell mould including upper and lower shell mould and level, the cope shell top has the round platform shape cavity that the several is used for forming valve body surface boss, is equipped with the intercommunication cavity perpendicular exhaust hole outside with the shell mould on the cope shell of this cavity top, the upper surface of cope shell be equipped with several ways feed through the hole of exhausting perpendicularly on the horizontal guiding gutter of port. The utility model has the advantages of: the utility model discloses technical scheme's shell mould adopts tectorial membrane arenaceous shell molding die skill, and the psammitolite adopts chromite sand coremaking technology, and the structure is more stable, and intensity is higher, non -deformable, the utility model discloses technical scheme will change into the top surface by original molding shell mould bottom surface, make the psammitolite utilize the main aperture to have the support, solve psammitolite fracture problem, the utility model discloses technical scheme is because this product main aperture runner is less, and the unable exhaust hole of settling, so must set up the body whistler at the shell mould boss, improves the emergence that the exhaust capacity prevented the gas pocket.
Description
Technical field
The utility model relates to a kind of injection moulding tool, especially a kind of inlet valve casting die.
Background technology
At present, the internal galleries that the shell mould of inlet valve foundry goods manufacturing process and core are formed is less, core easily ruptures, and cannot place arbor again, and due to the sprue of this product less, cannot riser runner be set, so cast(ing) surface easily forms bubble, therefore, a kind of core not easy fracture and bubble-free inlet valve casting die of cast(ing) surface is just badly in need of developing, through retrieval, do not find the same or analogous technical scheme with the utility model.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of core not easy fracture and bubble-free inlet valve casting die of cast(ing) surface.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of inlet valve casting die, and its innovative point is: the core comprising upper and lower shell mould and be horizontally placed in upper and lower shell mould;
Described cope shell top has several truncated cone-shaped cavity for the formation of valve body surface boss, cope shell above this cavity is provided with the vertical row pore being communicated with cavity and shell mould outside, is provided with several horizontal guiding gutter being communicated with vertical row pore upper port at the upper surface of cope shell;
Described mould also comprises a sandbox, described upper and lower shell mould embeds in sandbox, cavity between inside described upper and lower shell mould outer surface and sandbox is coated with layer of sand, be provided with the pouring and riser systems be communicated with shell mould in described layer of sand, described pouring and riser systems comprises a running channel and the rising head with shell mould quantity equity.
Further, one deck barrier paper is coated with between described shell mould and layer of sand.
Further, the diameter of described core runner is between 0.5 ~ 1.2cm.
The utility model has the advantage of: the shell mould of technical solutions of the utility model adopts resin-coated sand shell mould technique, and core adopts chromite sand core manufacturing craft, and structure is more stable, and intensity is higher, not yielding;
Technical solutions of the utility model will change into end face by original moulding shell mould bottom surface, make the core support that utilized main aperture to have, and solve core breakage problem;
Technical solutions of the utility model are less due to this product main aperture runner, and cannot settle steam vent, so must arrange body riser runner at shell mould boss, improve the generation that exhaust capacity prevents pore.
Technical solutions of the utility model design tank on original shell mould basis, are linked together by several steam vent, and then are connected to riser runner, and the water of each venthole can both be flowed out, and strengthen exhaust, and perfection solves the bubble phenomenon that cast(ing) surface exists.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model inlet valve casting die.
Fig. 2 is the side view of the utility model inlet valve casting die.
Detailed description of the invention
A kind of inlet valve casting die as depicted in figs. 1 and 2, the core 1 comprising upper and lower shell mould 2 and be horizontally placed in upper and lower shell mould.
Cope shell 2 top of the present utility model has several truncated cone-shaped cavity for the formation of valve body surface boss, cope shell 2 above this cavity is provided with the vertical row pore being communicated with cavity and shell mould 2 outside, is provided with several horizontal guiding gutter being communicated with vertical row pore upper port at the upper surface of cope shell 2.
Mould of the present utility model also comprises a sandbox 3, described upper and lower shell mould embeds in sandbox 3, cavity between inside upper and lower shell mould outer surface and sandbox 3 is coated with layer of sand, and be provided with the pouring and riser systems be communicated with shell mould in layer of sand, pouring and riser systems comprises a running channel and the rising head with shell mould quantity equity.
Be coated with one deck barrier paper between the shell mould 2 of technical solutions of the utility model and layer of sand, the sand when covering layer of sand can be stoped to fall in die cavity, affecting the qualification rate of product.
The diameter of core 1 runner of the present utility model is between 0.5 ~ 1.2cm, and core 1 is thinner, and technical solutions of the utility model will change into end face by original moulding shell mould bottom surface, makes core 1 support that utilized main aperture to have, and solves core breakage problem.
The shell mould 2 of technical solutions of the utility model adopts resin-coated sand shell mould technique, and core 1 adopts chromite sand core manufacturing craft, and structure is more stable, and intensity is higher, not yielding.
Technical solutions of the utility model are less due to this product main aperture runner, and cannot settle steam vent, so must arrange body riser runner at shell mould boss, improve the generation that exhaust capacity prevents pore.
Technical solutions of the utility model design tank on original shell mould basis, are linked together by several steam vent, and then are connected to riser runner, and the water of each venthole can both be flowed out, and strengthen exhaust, and perfection solves the bubble phenomenon that cast(ing) surface exists.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
