Technical Field
[0001] The utility model relates to a sand-leakage-proof sand-shooting head, belonging to the technical field of sand-shooting heads. Background Art
[0002] The sand-shooting head is a mechanism used for a molding machine to feed the mold on the molding machine.
[0003] However, the opening and closing of the existing sand shooting head is generally achieved by setting a valve on the feed pipe at the upper end of the sand shooting head. In actual use, there is a distance between the feed pipe and the sand shooting head. After the valve of the feed pipe is closed, the raw material retained in the sand shooting head will still flow out, causing sand leakage, which will be scattered on the molding machine and need to be manually cleaned. In view of the above shortcomings, the utility model proposes a sand shooting head that prevents sand leakage. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a leakage-proof sand-jetting head to solve the existing problems.

[0006] A further improvement is that a sand storage cavity is opened in the middle of the top surface of the sand blasting head body, a sand blasting plate groove is opened in the middle of the bottom surface of the sand blasting head body, a discharge port is opened between the sand storage cavity and the sand blasting plate groove, an opening and closing mechanism movable groove is opened on the right side of the sand blasting plate groove, and an opening and closing mechanism opening is opened between the sand blasting plate groove and the opening and closing mechanism movable groove.
[0007] A further improvement is that the feed pipe cover comprises a cover body and a feed pipe opening disposed in the middle of the cover body.
[0008] As a further improvement, the sandblasting plate comprises a spray plate, a plurality of sandblasting holes arranged at intervals on the spray plate, and an opening and closing plate slide groove connecting the sandblasting holes is arranged on the right side of the spray plate.
[0009] A further improvement is that the opening and closing plate includes an opening and closing plate body, a plurality of sandblasting opening and closing holes are spaced apart on the top surface of the opening and closing plate body, the opening and closing plate body is movably sleeved in the opening and closing plate slide groove from right to left, and the diameter of each sandblasting opening and closing hole is larger than the diameter of each sandblasting hole by 2 mm.
[0010] A further improvement is that a lifting structure is also provided on the top surface of the lifting frame.
[0011] The beneficial effects of the utility model are:
[0012] The utility model provides a sand-leakage-proof sand-shooting head, which is formed by a structural combination design of a sand-shooting spray plate, an opening and closing mechanism at the bottom end of the sand-shooting head. A draw-plate opening and closing valve design is adopted at the bottom end of the sand-shooting head, so that the opening and closing of the sand-shooting head is carried out at the bottom end. When the bottom end of the sand-shooting head is closed, the raw materials between the sand-shooting head and the feeding pipe will not flow downward and leak sand, thereby solving the sand leakage problem of the existing sand-shooting head and improving the sand-leakage-proof performance of the sand-shooting head.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figure 1-Figure 5The utility model provides a schematic diagram of a leak-proof sand-shooting head technical solution: it includes a sand-shooting head 1, a sand-shooting blasting plate 2 connected and sleeved on the bottom surface of the sand-shooting head 1, and an opening and closing mechanism 3 movably sleeved on the middle part of the right side of the sand-shooting blasting plate 2 to open and close the sand-shooting blasting plate 2. The top surface of the sand-shooting head 1 is connected with a feed pipe 4, and a lifting frame 5 is arranged on the upper end of the sand-shooting head 1. The sand-shooting head 1 is composed of a sand-shooting head body 11 and a feed pipe surface cover 12. The opening and closing mechanism 3 includes an opening and closing plate 31, and a telescoping device 32 is transversely arranged on the right side of the opening and closing plate 31. A sand storage cavity 111 is opened in the middle part of the top surface of the sand-shooting head body 11, and a sand-shooting blasting plate groove 113 is opened in the middle part of the bottom surface of the sand-shooting head body 11. A discharge port 112 is opened between the sand storage cavity 111 and the sand-shooting blasting plate groove 113. The sand-shooting blasting plate groove 113 is on the right side. An opening and closing mechanism movable groove 114 is opened on one side, an opening and closing mechanism opening 115 is opened between the sandblasting plate groove 113 and the opening and closing mechanism movable groove 114, the feed pipe face cover 12 comprises a face cover body 121, a feed pipe opening 122 opened in the middle of the face cover body 121, the sandblasting plate 2 comprises a spray plate 21, a plurality of sandblasting holes 22 are opened on the spray plate 21 at intervals, an opening and closing plate slide groove 23 connecting each of the sandblasting holes 22 is opened on the right side of the spray plate 21, the opening and closing plate 31 comprises an opening and closing plate body 311, a plurality of sandblasting opening and closing holes 312 are opened on the top surface of the opening and closing plate body 311 at intervals, the opening and closing plate body 311 is movably sleeved in the opening and closing plate slide groove 23 from right to left, and the diameter of each of the sandblasting opening and closing holes 312 is 2 mm larger than the diameter of each of the sandblasting holes 22.
[0020] Working principle:
[0021] When the lifting structure extends downward through the lifting frame 5, the sandblasting head 1 moves downward and contacts the mold on the molding machine, and then the telescopic device 32 on the opening and closing mechanism 3 extends to the left, pushing the opening and closing plate body 311 to slide to the left in the opening and closing plate slide groove 23, so that each sandblasting opening and closing hole 312 is connected with each sandblasting hole 22 in a one-to-one correspondence. Since the diameter of the sandblasting opening and closing hole 312 is 2 mm larger than the diameter of the sandblasting hole 22, the sandblasting hole 22 can be opened to allow the raw material to enter at the maximum flow rate. When the feed pipe 4 squeezes the sand storage cavity 111 on the sandblasting head 1 to feed the material, the raw material will pass through each The connection between the sandblasting opening and closing hole 312 and each sandblasting hole 22 is squeezed into the mold on the molding machine. Under the action of extrusion feeding, the extrusion feed in the mold cavity is filled. After completion, the telescopic device 32 shrinks to the right, pulling the opening and closing plate body 311 to slide to the right in the opening and closing plate slide groove 23, so that each sandblasting opening and closing hole 312 and each sandblasting hole 22 are misaligned one by one, and the spray plate 21 on the bottom surface of the sandblasting head 1 is closed. Because the spray plate 21 is at the bottom, the raw material in the sand storage chamber 111 will not flow downward, thereby realizing the sand leakage protection of the sandblasting head.
