Description

Cast sanding device

Technical field

A kind of casting sanding device is the utility model is related to, belongs to technology of die manufacturing field.

Background technology

In lost foam casting process, some castings white mould used is an entirety, also, white mould is complex-shaped, type Intracavitary duct is more, and adds sand using rain type more during moulding so that in many die cavities plus sand is not in place or add less than sand, so Require to want dialogue mould to carry out pre- sand filling process before moulding is poured into a mould, i.e., it is advance to adding the cavity space less than sand to carry out during moulding Back-up sand, its method are that white mould is placed on plain jolter, and dry sand is loaded onto with container, and the sand inlet by white mould is to adding less than sand Dry sand is injected in space, is blocked after sand is filled up to sand inlet, then to sand inlet.Existing sanding device once can only Pre- back-up sand is carried out to a die cavity, pre- back-up sand is less efficient, has had a strong impact on the speed of casting；In pre-fill, due to sand Amount is not fixed so that sand is more or less during pre-fill process, and sand is more, and Bai Mo can be deformed, and cause casting to have flaw or report Useless, sand is few so that back-up sand is not in place, and leaving a blank space, and during casting solution, solution can reach this space, cause to cast After part shaping, the scab block of not easy-clear is formd, increases the difficulty of cleaning, causes labor strength high, when serious, also Casting can be caused to scrap.

Utility model content

Deficiency of the prior art, the technical problems to be solved in the utility model are more than：A kind of pre- back-up sand is provided Efficiency is higher, also, pre- back-up sand amount accurately casts sanding device.

Casting sanding device described in the utility model, including support body, the upper end of support body are fixed with storage sand warehouse, store up sand warehouse Lower section is provided with least two plus sand bucket, and respectively plus sand bucket is each attached on support body, respectively adds the charging aperture of sand bucket by corresponding to it The discharging opening of sand warehouse is stored up in feeding-passage connection, and inlet valve is equipped with each feeding-passage, and respectively plus sand bucket is transparent material, is respectively added Graduation mark is equipped with the outer webs of sand bucket, respectively adds the bottom of sand bucket to be equipped with and adds sand mouth, respectively plus on sand mouth be equipped with outlet valve, Respectively plus the bottom of sand mouth is respectively connected with plus sandpipe.

Above-mentioned respectively adds sandpipe to be flexible pipe, can change the discharging direction for adding sandpipe as needed, be easy to die cavity back-up sand.

Above-mentioned support body is provided with the pipe clamp corresponding with respectively adding sandpipe, respectively adds the end of sandpipe to be connected to corresponding to it On pipe clamp, when not in use, sandpipe can will be added to be stuck on pipe clamp, and effectively prevent plus sandpipe swings damage.

The bottom of above-mentioned support body is provided with least three wheels, is easy to movement of the present utility model.

Operation principle and process：

Dry sand is previously added in storage sand warehouse, in use, first opening inlet valve, dry sand is entered from storage sand warehouse and adds sand bucket, By observing graduation mark, when the dry sand amount for adding the dry sand amount in sand bucket to reach required in die cavity, inlet valve is closed, from pipe clamp Remove plus sandpipe, alignment die cavity, opening outlet valve can carry out pre- back-up sand manipulation.

Possessed beneficial effect is the utility model compared with prior art：

Casting sanding device described in the utility model, simultaneously multiple die cavities can be carried out with pre- back-up sand operation, pre- back-up sand effect Rate is higher；Also, add sand bucket to be provided with graduation mark, accurately control pre- sand feeding amount, prevent dry sand and fill out more or fill out less and shadow Casting quality is rung, effectively increases the qualification rate of casting, reduces the labor intensity of worker.

Brief description of the drawings
