Description

Technical Field

[0001] The utility model relates to the technical field of sand shooting, in particular to a self-cleaning fast-adjusting sand shooting plate. Background Art

[0002] In casting production, it is necessary to use sand core molds to make corresponding sand cores. The molding process of the sand core is generally to use a core shooter to shoot the coated sand from the sand shooting port reserved on the mold into the mold cavity at high pressure, and then crust and form under the heating of the high-temperature mold. Since the shapes and sizes of casting sand cores are different, the positions of the sand shooting ports of various types of sand core molds cannot be unified. In the prior art, a sealing gasket is usually manually pasted on the sand shooting plate of the core shooter according to the shape of the mold, and then the sealing gasket is cut according to the position of the sand shooting port of the mold so that the sand outlet (nozzle) of the sand shooting plate can be aligned with the sand shooting port on the mold. This operation is not only cumbersome and labor-intensive, but also has a great loss of sealing gaskets in the case of frequent mold switching, and the cost of production consumables is high. Moreover, since the coated sand will agglomerate due to the influence of air humidity, there is a risk that the agglomerated coated sand will enter the mold cavity or block the sand shooting hole of the mold, causing abnormal production interruption. Furthermore, because sand core molds are constantly exposed to high temperatures during production, the coated sand remaining at the sand outlet of the sandblasting plate after sandblasting can harden and form a crust that is difficult to remove. During secondary production, this crust can often be injected into the mold cavity, causing product defects. In severe cases, the sand outlet can even be directly heated and hardened, resulting in a crust that causes sandblasting anomalies. Utility Model Content

[0040] A sand retaining plate 2 is provided in the groove 31. The adjusting block 4 and the sand-shooting plate body 3 are respectively locked with the sand retaining plate 2. The sand retaining plate 2 is fitted with the second end of the adjusting block 4, thereby forming a gap 7 between the sand retaining plate 2 and the bottom surface 311 of the groove 31. The gap 7 can be connected to the mounting through hole 32.

[0041] The back side of the sandblasting plate body 3 is provided with a sealing plate 6 fitted therewith, and the sealing plate 6 is provided with a clearance through hole 61 corresponding to the mounting through hole 32;

[0042] An air passage is provided in the sandblasting plate body 3 , an air inlet end of the air passage is connected to an external air source, and the air passage is communicated with the mounting through hole 32 .

[0043] The mounting through hole 32 tapers from the first end to the second end, and the profile of the adjustment block 4 matches the mounting through hole 32 .

[0044] The adjustment block 4 is preferably in the shape of a quadrangular pyramid.

[0045] See also Figure 6 、 Figure 7 The air passage includes two long passages 34 spaced apart, one end of each of the two long passages 34 being connected to a joint 1 provided on one side of the length direction of the sandblasting plate body 3; the other ends of the two long passages 34 are both located on the other side of the length direction of the sandblasting plate body 3, and a plug 12 for opening or closing the port is provided;

[0046] The two long channels 34 are connected via a short channel 35 to form an annular channel surrounding the circumference of the sandblasting plate body 3;

[0047] Each mounting through hole 32 is connected to the long channel 34 through two branch channels 33 spaced apart from each other; the two branch channels 33 are preferably connected to the two sides of the mounting through hole 32 respectively;

[0048] The two ends of the short channel 35 are respectively located on the two side surfaces in the width direction of the sandblasting plate body 3, and plugs 12 for opening or closing the short channel 35 are provided at the ends.

[0049] Specifically, the plug 12 is a stop screw.

[0050] Specifically, a washer 11 is provided between the sand retaining plate 2 and the sand shooting plate body 3 , and they are connected by fixing screws 9 .

[0051] Specifically, the sand retaining plate 2 and the adjusting block 4 are locked and connected by an adjusting screw 5 and a screw sleeve 8 . The screw sleeve 8 is located on one side of the sand retaining plate 2 , and a protective cover 10 is provided on the screw sleeve 8 .

[0052] For details, see Figure 1 and Figure 4 A circle of card grooves is provided on the reverse side of the sandblasting plate body 3, and a flange 62 is provided around the edge of the sealing plate 6 to fit in the card groove; the reverse side of the sandblasting plate body 3 and the sealing plate 6 are glued together.

[0053] Specifically, the sealing plate 6 is made of rubber.

[0054] The working principle and process of this embodiment are as follows:

[0055] When in use, lock the assembled sand shooting plate into the sand outlet of the core shooting machine, install the mold, and remove the adjustment block 4 on the sand shooting plate body 3 corresponding to the position of the mold sand shooting outlet. Figure 4 In this embodiment, only four of the five mounting holes 32 are installed with adjustment blocks 4, and the mounting hole 32 aligned with the sand shooting port is not installed with an adjustment block 4. Then the core shooting machine is started, and the sand shooting plate begins to move downward until the sealing plate 6 is pressed against one side of the sand shooting port of the mold. The core shooting machine starts to apply pressure and sprays the coated sand. At this time, the coated sand first passes through the gap 7 between the sand retaining plate 2 and the sand shooting plate body 3, and then flows into the mounting holes 32 where the adjustment blocks 4 are not installed, and then flows out from the corresponding clearance holes 61 on the sealing plate 6. Because the sealing plate 6 presses the mold, a closed cavity is formed between the two, and the gushing coated sand is directly sprayed onto the sand shooting port of the mold, and finally the coated sand enters the mold cavity, completing the production.

[0056] After the coated sand is punched, the sandblasting plate is lifted and air is blown through the connector 1 on the connecting device. The compressed gas flows through the air channel inside the sandblasting plate body 3 and is ejected from the mounting hole 32 where the adjusting block 4 is not installed through the branch channel 33, thereby blowing off the coated sand crusted on the surface of the sealing plate 6 and completing the cleaning work.

[0057] Those skilled in the art will understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
