[0007] The guide frame is L-shaped.
[0008] As a further description of the above technical solution:
[0009] The flow guide pipe is L-shaped.
[0010] As a further description of the above technical solution:
[0011] The inner annular surfaces of the water spray limiting sleeves are all spray surfaces.
[0012] As a further description of the above technical solution:
[0013] The opening arc of the guide opening is less than 180 degrees.
[0014] As a further description of the above technical solution:
[0015] The water spray limiting sleeve is made of metal.
[0016] Compared with the prior art, the utility model provides a metal casting mold drilling machine, which has the following beneficial effects:
[0017] 1. In the utility model, by designing a water spray limit sleeve and opening a guide port, it is possible to prevent the flying of punched debris, and the flushing water flow takes the debris out from one direction of the guide port, so that the area on the template that needs to be cleaned becomes smaller;
[0018] 2. In the utility model, the guide frame has an up-and-down guiding function for the guide pipe, can fix the position of the water spray limit sleeve, and has a simple structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 2 It is a schematic diagram of the three-dimensional structure of the utility model.
[0021] Legend:
[0022] 1. Drilling machine; 2. Drilling head; 3. Water spray limit sleeve; 4. Guide port; 5. Guide frame; 6. Guide pipe; 7. Limit ring; 8. Water pipe. DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example:
[0025] See also Figure 1-Figure 2 The utility model provides a metal casting mold drilling machine, including a drilling machine 1, a drilling head 2 is provided at the bottom of the drilling machine 1, a water spray limit sleeve 3 is sleeved on the drilling head 2, the water spray limit sleeve 3 is a hollow structure, and the water spray limit sleeve 3 is provided with a guide port 4, a guide frame 5 is fixedly installed on the back of the drilling machine 1, a guide pipe 6 is installed at the vertical pipe position of the guide frame 5, the lower end of the guide pipe 6 is connected and fixedly connected with the water spray limit sleeve 3, a limit ring 7 is provided at the upper end of the guide pipe 6, and the upper end of the guide pipe 6 is connected to the installation water pipe 8.
[0026] Specifically, Figure 2 As shown, the guide frame 5 is L-shaped, and the guide pipe 6 is L-shaped, which is convenient for fixing and simple for insertion.
[0027] Specifically, Figure 1 and Figure 2 As shown, the inner annular surface of the water spray limiting sleeve 3 is a spray surface, and the spray surface is large.
[0028] Specifically, the opening arc of the guide opening 4 is less than 180 degrees to prevent water from overflowing due to an opening that is too large and debris from being unable to come out due to an opening that is too small.
[0029] Specifically, the water spray limit sleeve 3 is made of metal, will not be damaged by flying debris, and is relatively durable.
[0030] Working principle:
[0031] When in use, the limiting ring 7 has a limiting effect on the descent of the water spray limiting sleeve 3 and the guide pipe 6. When the drilling machine 1 descends to drill a hole, the water spray limiting sleeve 3 contacts the mold plate, and the debris generated by the drilling head 2 is blocked by the water spray limiting sleeve 3 so that it does not fly around. Then the water pipe 8 guides water from the guide pipe 6 into the water spray limiting sleeve 3, and the water spray limiting sleeve 3 sprays toward the drilling position of the drilling head 2, and the debris only flows out from one direction of the guide port 4, which is easier to clean.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
