Description

Core making machine sand ejection board

Technical field

The utility model relates to core making machine fields, and in particular to core making machine sand ejection board.

Background technique

Traditional shell core coremaking equipment, its blasting unit and sand ejection board are separated structure, one as mold of sand ejection board Point, it is fixed on mold, when changing the mold coremaking or is replaced with dedicated sand ejection board matched with corresponding mould or is penetrated with one kind The biggish general sand ejection board of sand mouth, there is higher cost and occupied space in the former, the latter is main in entire production process It wants that there are the following problems: 1, connecting not close between sand ejection board and blasting unit, sand can be leaked out from gap when penetrating sand, be caused Waste and pollution；2, larger due to penetrating sand mouth, some will remain in die surface to the sand projected, influence the molding of sand core Effect；3 make a slip of the tongue greatly due to penetrating sand, and pressure is not enough concentrated when penetrating sand, will lead to the problem of that penetrate sand not firm, further influence finished product Quality.

Utility model content

In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide can be according to different molds Open and close the good core making machine sand ejection board of corresponding sand-spraying hole, using flexible, sealing effect.

To realize the above-mentioned technical purpose, the utility model provides following technical solution:

Core making machine sand ejection board, including mainboard, the mainboard are equipped with several mounting holes, it is characterised in that: the mainboard top The middle part in face is equipped with caulking groove, and the first sand-spraying hole for having several proper alignments is run through from the caulking groove bottom to the mainboard bottom surface, Matched silica gel plate is removably embedded on the caulking groove, the silica gel plate is equipped with and penetrates with part described first Corresponding second sand-spraying hole of sand hole.

The mainboard surface is set as layer of silica gel.

The mounting hole is kidney slot.

First sand-spraying hole and second sand-spraying hole are the identical cylindrical structure of diameter.

The caulking groove bottom surface is equipped with several fixture blocks, and the fixture block is distributed between the first adjacent sand-spraying hole, the silica gel Plate is equipped with the card slot to match with the fixture block.

The fixture block is rectangular parallelepiped structure.

The silica gel plate protrudes from the mainboard surface.

It after the above technical solution is adopted, the beneficial effects of the utility model are: can be according to different molds on mainboard Different silica gel plates is installed, to open and close corresponding with mold the first sand-spraying hole, not only using flexible, and with good sealing Effect achievees the purpose that province's sand and improves sand core molding effect.

Detailed description of the invention

The utility model has following attached drawing:

Fig. 1 is the schematic diagram of the utility model；

Fig. 2 is that Fig. 1 removes the schematic diagram after silica gel plate 2；

Fig. 3 is the side view of Fig. 1.

Specific embodiment

As shown, core making machine sand ejection board, including mainboard 1, the mainboard 1 are equipped with several mounting holes 11, pass through installation Mainboard 1 can be mounted on mold by hole 11, and the middle part of 1 top surface of mainboard is equipped with caulking groove 12, from 12 bottom of caulking groove to institute Stating mainboard bottom surface and running through has the first sand-spraying hole 121 of several proper alignments, be removably embedded on the caulking groove 121 and its The silica gel plate 2 to match, in the present embodiment, the silica gel plate 2 protrude from 1 surface of mainboard, and silica gel plate 2 is completely fitted In caulking groove 12, the leakproofness between product and blasting unit is effectively increased by silica gel plate 2, sand is from gap when preventing from penetrating sand Outflow, avoids the waste of sand.The silica gel plate 2 is equipped with and first sand-spraying hole 121 corresponding second of partial amt Sand-spraying hole 21, since the plasticity of silica gel plate 2 is strong, the position of the second sand-spraying hole 21 on silica gel plate 2 and size can be right for its The mold answered and design, this structure, which is able to achieve, accurately injects sand formed in mould technical effect, effectively improves sand core shape Molding effect, not only overcome and do not penetrated sand mode bring accurately in the past and penetrate the not firm problem of sand, and avoid it is extra Sand remains in the phenomenon that die surface, prevents sand from polluting and wasting, penetrates sand effect to further increase, first sand-spraying hole 121 with second sand-spraying hole 21 be the identical cylindrical structure of diameter, and sand is swimmingly from the second sand-spraying hole 21 when guaranteeing to penetrate sand It is middle to enter the first sand-spraying hole 121.

For the sealing effect for further increasing product, it is equipped with heat conduction silicone on 1 surface of mainboard,

For guarantee mainboard 1 be accurately mounted on mold, the mounting hole 11 be kidney slot, make mainboard 1 can as needed into The adjustment of row left-right position.

In order to further increase the chimeric tightness of silica gel plate 2 Yu caulking groove 12,12 bottom surface of caulking groove is equipped with several fixture blocks 122, the fixture block 122 is distributed between the first adjacent sand-spraying hole 121, and the silica gel plate 2 is equipped with and 122 phase of fixture block Matched card slot, the fixture block 122 are rectangular parallelepiped structure.

To sum up, this product can install different silica gel plates 2 according to different molds on mainboard 1, with folding and mold Corresponding first sand-spraying hole 121, not only using flexible, and there is good sealing effect, reach province's sand and improve sand core at The purpose of type effect.
