Description
Technical field
The utility model is related to casting core to equip field, and in particular to a kind of light-duty hot core machine sand ejection board of sand leakage avoiding.
Background technology
Core surface quality depends not only on core box technological design, and in actual production, coremaking frock is to core quality
Influence it is also particularly important, such as the sand ejection board with core box directly contact just plays very crucial work in this course
With.The operation principle of hot box is that the sand material for being mixed into foundry sand, thermosetting resin and curing agent is penetrated by certain pressure
In entering the core box with heater（200~230 DEG C）, make to press close to the sand material of box surface to be heated, under temperature action, it glues
Knot agent within a very short time can polycondensation and harden, formed core.In this course, the sand material being mixed into is directly by penetrating
Sand plate enters core box interior（The material of sand ejection board is 45# steel, and core box material is HT250）, penetrate sand and complete rear portion sand material meeting
Between retaining in sand ejection board hole or internal, the core box due to sand ejection board with 220 DEG C or so is contacted and is operated（Time of contact regards sand
Depending on type quality, generally 1 ~ 6s）, because of the heat conductivility of sand ejection board material, in the case of time of contact long enough, itself temperature
Degree can also reach 80 ~ 120 DEG C, and the softening temperature of sand material polymer is at 90 ~ 110 DEG C（Primary solidification form）, it is preliminary in sand material
In the case that condition of cure is formed, the sand material of sand ejection board interior contact high temperature can occur curing reaction, form not of uniform size gathering
Zoarium, then enters core box die cavity by penetrating sand again.Its produced solidification condensate can cause core surface produce space
With the untight core defect of tissue.Former sand ejection board structural disadvantages 1：Deadweight is excessive；Shortcoming 2：When sand ejection board is contacted with core box face
Because thermal deformation and mating surface cause race sand serious without sealing function；Shortcoming 3：Sand ejection board can accelerate temperature with core box directly contact
Transmission, causes roughing sand premature cure；Shortcoming 4：Because loophole size is fixed, its applicability is reduced（For small or big specification
Core box is not generally applicable）.
The content of the invention
The utility model proposes a kind of light-duty hot core machine sand ejection board of sand leakage avoiding, the technical problem to be solved is sand material preceding
Phase produces condensate because of heat conduction high temperature, and then influences core quality；There are race sand and leakage sand phenomenon in core-shooting process.
The technical solution of the utility model：
The light-duty hot core machine sand ejection board of sand leakage avoiding, it includes plate body, seal gasket, water circulation pipe, fixing hole, silk hole, plate
Body is rectangular-shape plate, and the upper and lower both sides of plate body are designed with and water circulation pipe is housed in the middle of fixing hole, plate body, and plate body is contacted with core box
A side end face on seal gasket is housed, plate body medium design has several hole shapes in a row, and being rotated in described silk hole has
Soket head cap screw.
Described water circulation pipe is U-tube road, and one end is water inlet, and the other end is delivery port.
Silk hole and fixing hole on described seal gasket correspondence plate body are also provided with corresponding circular hole, and seal gasket vulcanization connects
It is connected on plate body side.
Described plate body is aluminum alloy material.
The utility model has the advantages that replace 45# steel to make sand ejection board using aluminum alloy material, from heavy and light（It is original weight
1/2）；End face is contacted with core box in sand ejection board and places rubber blanket, this technique can effectively prevent from running sand problem；Increase in sand ejection board
Add water circulatory function, often penetrates sand and completes once, that is, circulate 10s（Less than pitch time）, the method can effectively solve roughing sand and shift to an earlier date
Problem of solidification；Change injection nozzle structure design, can be according to core box size using the interior spiral shell angle aperture designs of G1/4（Size）Flexibly adjust
Section penetrates sand scope（Blocked no）.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is A-A of the present utility model to sectional view.
Specific embodiment
Referring to the drawings 1-2, the light-duty hot core machine sand ejection board of sand leakage avoiding, it include plate body 1, seal gasket 2, water circulation pipe 3,
Fixing hole 4, silk hole 5, plate body 1 are rectangular-shape plates, and plate body is designed with fixing hole 4 in both sides, is followed equipped with water in the middle of plate body 1 about 1
Endless tube road 3, is equipped with seal gasket 2 on the side end face that plate body 1 is contacted with core box, the medium design of plate body 1 has several shapes of hole 5
In a row, rotation has soket head cap screw in described silk hole 5.
Described water circulation pipe 3 is U-tube road, and one end is water inlet, and the other end is delivery port.
Silk hole and fixing hole on the described correspondence plate body of seal gasket 2 are also provided with corresponding circular hole, and seal gasket 2 vulcanizes
It is connected to the side of plate body 1.
Described plate body 1 is aluminum alloy material.
When the utility model is used, plate body is fixedly connected through fixing hole by soket head cap screw with core box, plate body and core
Seal gasket is housed, it is ensured that sand will not be run, staff as needed can be by soket head cap screw silk between box contact surface
Hole blocks a part, and the silk hole of remainder so ensures that and penetrate sand targetedly as nozzle, improves operating efficiency.
