Description
Technical field
The utility model relates to die casting field, is specifically related to a kind of shell core box for casting sand core.
Background technology
Resin sand shell core process is a kind of core manufacturing craft of precision, and shell core box is process unit resin sand being made core.Shell core machine is a kind of mo(u)lding equipment producing shell core, and shell core box is arranged on shell core machine, produces shell core by the operation of shell core machine equipment.The operation principle of shell core machine: left and right core shell matched moulds, is blown in shell core box by resin sand; After blast terminates, blast bucket stays for some time and crusts, and investing time is generally 15-50S, and thickness is determined as required; After reaching the crust thickness of regulation, shell core box is overturn 180 °, the core core sand do not crusted is poured out; Again core box is continued heating about 2min, die sinking after shell hardens completely, ejects core from core box, and artificial taking-up is stand-by.The production efficiency of shell core box higher than hot box, but lower than cold-box.The core box height of shell core box can not lower than 510mm, and this size is determined by shell core machine.For the fuse (fuse height is less than 250mm) that size is less, the moulding section of core is only positioned at the first half of core box, and the latter half can not be effectively utilized, and causes certain waste.
Utility model content
The purpose of this utility model is to provide a kind of shell core box, changes monolateral coremaking into bilateral coremaking, improves the utilization rate of shell core box.
For achieving the above object, the technical scheme that the utility model adopts is: comprise left core shell and right core shell, the inner die cavity formed for shaping core after left core shell and right core shell matched moulds, the inside upper-lower position of left core shell is provided with upper left die cavity and lower-left die cavity, the inside upper-lower position of right core shell is provided with upper right die cavity and bottom right die cavity, matched moulds rear left upper impression and upper right die cavity form the upper impression being used for shaping core, and matched moulds rear left lower impressions and bottom right die cavity form the lower impressions being used for shaping core.
Preferably, described upper left die cavity and lower-left die cavity are all laterally provided with two side by side, and upper right die cavity and bottom right die cavity are all laterally provided with two side by side.
Preferably, described upper left die cavity, lower-left die cavity, upper right die cavity and bottom right die cavity are equipped with the sand-spraying hole for blast.
Preferably, between described upper left die cavity and lower-left die cavity the spreader stopping gravel circulation, is equipped with between upper right die cavity and bottom right die cavity.
Preferably, position that described left core shell contacts with right core shell is provided with buckles pin, and right core shell is provided with and the pin hole of buckleing pin and matching.
After adopting technique scheme, the utility model has following good effect:
(1) shell core box of the present utility model, be divided into upper impression and lower impressions, each die cavity is shaping two cores of energy all, shell core box can shaping four cores, change existing can only in the die cavity of one side the defect of shaping core, change monolateral coremaking into bilateral coremaking, the production efficiency of core doubled, improve the utilization rate of core box simultaneously, avoid the waste caused because core height is less.
(2) the shell core box in the utility model is provided with spreader between upper impression and lower impressions, when with mold cavity forming core or core shaping by lower impressions, spreader can prevent gravel from being dispelled in the die cavity that do not work, ensures core Forming Quality and shaping efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in figures 1 to 6, be shell core box of the present utility model, comprise left core shell 1 and right core shell 2, the inner die cavity formed for shaping core after left core shell 1 and the 2-in-1 mould of right core shell.Left core shell 1 contacts with right core shell 2 position is provided with and buckles pin 13, and right core shell 2 is provided with and the pin hole of buckleing pin 13 and matching, and by the combination of button pin 13 with button hole, makes left core shell 1 and right core shell 2 can free deciliter.
The inside upper-lower position of left core shell 1 is provided with upper left die cavity 11 and lower-left die cavity 12, upper left die cavity 11 and lower-left die cavity 12 are all laterally provided with two side by side, be provided with the spreader 4 stopping gravel circulation between upper left die cavity 11 and lower-left die cavity 12, upper left die cavity 11 and lower-left die cavity 12 be equipped with the sand-spraying hole 3 for blast.
The inside upper-lower position of right core shell 2 is provided with upper right die cavity 21 and bottom right die cavity 22, upper right die cavity 21 and bottom right die cavity 22 are all laterally provided with two side by side, be provided with the spreader 4 stopping gravel circulation between upper right die cavity 21 and bottom right die cavity 22, upper right die cavity 21 and bottom right die cavity 22 be equipped with the sand-spraying hole 3 for blast.Matched moulds rear left upper impression 11 and upper right die cavity 21 form the upper impression being used for shaping two cores, matched moulds rear left the lower impressions 12 and lower impressions that formed for shaping two cores corresponding with bottom right die cavity 22 position.
In use, first by left core shell 1 and the 2-in-1 mould of right core shell, shell core box, to blast in upper impression, after stopping 15-50S, is overturn 180 °, is poured out the gravel do not crusted in core shell core box of the present utility model by blast bucket.After upset terminates, shell core box, to blast in lower impressions, after stopping 15-50S, is overturn 180 °, is poured out the gravel do not crusted in core by blast bucket again.Heat about 2min again, core ejects by die sinking, namely makes core for subsequent use.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain that the utility model requires.
