As a further optimization, the filter plate comprises a plate body and supporting columns, one end of each supporting column is arranged at the lower end of the plate body, and the other end of each supporting column is positioned on the sand shooting plate.

As a further optimization, the filter plate further comprises a locking bolt, and the locking bolt penetrates through the body and the supporting column in sequence and then extends into the sand shooting plate; the support column has vertical dodge hole, sets up and dodges the hole and can be used for the bolt to pass.

As a further optimization, the plate body is a wear-resistant steel plate, and the thickness of the plate body is six to ten millimeters.

As a further optimization, the number of the supporting columns is two to four, preferably three, and three supporting columns have better supporting stability.

As a further optimization, the height of the supporting column is smaller than the width of the waist-shaped shunting hole on the sand shooting head.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model forms a horizontal gap by arranging the filter plate, and the horizontal gap has a larger space, so that the overall passing rate is not influenced even if one part of the horizontal gap is blocked, and the sand grains passing through the waist-shaped shunting holes of the sand shooting head are standard sand grains, thus being smooth and unobstructed;

2. the sand block blocked in the filter plate can be automatically crushed by colliding with sand grains through a plurality of times of high pressure, and manual cleaning is also avoided.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 6, a core box machine sand shooting mechanism comprises a sand preparing bin 10, a sand shooting plate 20 and a sand shooting head 30, wherein the sand shooting plate 20 is installed at the bottom end of the sand shooting bin 10, a through hole 201 communicated with the sand shooting bin 10 is formed in the sand shooting plate 20, the sand shooting head 30 is installed at the through hole 201, the core box machine sand shooting mechanism further comprises a filter plate 40, the filter plate 40 is installed on the sand shooting plate 20 and located above the through hole 201, the diameter of the filter plate 40 is larger than that of the through hole 201, and a horizontal gap 400 is formed between the filter plate 40 and the sand shooting plate 30 for allowing sand materials 100 to enter the through hole 201 from the sand preparing bin 10.

The utility model discloses in, sand material 100 places in shooting storehouse 10 through feed inlet 101, then blows sand material to shooting plate's through-hole 201 department through high pressure gas, compare in the conventionality, throw sand and pile up on shooting head's flow distribution plate ready, as shown in fig. 6, receive the high pressure influence, the sand piece blocks up shooting head's flow distribution hole very easily, the leading cause, the flow distribution hole area is little (only three waist shape hole), and accumulated sand axial blows in and does not have the buffering area, very easily by sand piece fill up, however the utility model discloses in, because the filter exists, sand material piles up on the filter, shooting head's 30 flow distribution plate 31 is not accumulated sand, receive the high pressure influence, sand piece can be blocked up between filter and shooting plate, and sand grain flows into through-hole 201 from filter horizontal clearance all around, sand material is for preparing sand storehouse 10, horizontal clearance 400, through-hole 201, shooting head's feed inlet 301, shooting head's flow distribution shape hole 310 is by the waist shape flow distribution hole 400, even if it is more big sand piece passes through the horizontal clearance of a pair of sand core box, because it is located sand hole, even if it is the whole smooth to pass through sand grain space, it is by the smooth to pass through the discharge gate 310; moreover, the sand block blocked on the filter plate is impacted with sand grains through multiple times of high pressure, and can be automatically crushed, and manual cleaning is also avoided.

The concrete structure of filter 40 includes plate body 41 and support column 42, and the plate body is wear-resisting steel sheet, and its thickness is eight millimeters, and the one end of three support column 42 sets up in the lower extreme of plate body 41, and the other end is positioned on shooting board 30, specifically is: the locking bolt 43 sequentially passes through the locking hole 411 of the body 41 and the supporting column 42 and then extends into the sand shooting plate 20, and in cooperation with the locking bolt, the supporting column 42 is provided with a vertical avoiding hole coaxial with the locking hole for the locking bolt to pass through.
