[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] See also Figures 1 to 3As shown, a mold drilling device includes a support plate 1, a supporting assembly 2, a first driving part 3, a drilling assembly 6, a second driving part 4, a third driving part 5 and a protective assembly 7. The support plate 1 is a rectangular workbench, and legs 11 are respectively provided at the four corners of the bottom thereof, for supporting the support plate 1. The supporting assembly 2 is arranged above the support plate 1, for supporting and fixing the mold. The drilling assembly 6 is arranged above the supporting assembly 2, for drilling the mold from top to bottom. The protective assembly 7 is sleeved on the lower part of the drilling assembly 6, for preventing debris from splashing during drilling. The first driving part 3 is fixedly arranged on the top surface of the support plate 1, located between the support plate 1 and the supporting assembly 2, for driving the supporting assembly 2 to move along the X-axis of the support plate 1. The second driving part 4 is arranged on one side of the drilling assembly 6, for driving the drilling assembly 6 to rise and fall. The third driving part 5 is mounted above the support plate 1, and is located on one side of the second driving part 4, for driving the second driving part 4 to move along the Y-axis direction of the support plate 1.

[0023] During implementation, the staff fixes the mold above the supporting assembly 2, starts the first driving unit 3, and the first driving unit 3 drives the mold to move along the X-axis direction to the bottom of the drilling assembly 6, and then starts the third driving unit 5, and the third driving unit 5 drives the second driving unit 4 to move along the Y-axis direction until the output end of the drilling assembly 6 corresponds to the position where the hole needs to be drilled, and then starts the second driving unit 4 to drive the drilling assembly 6 to move downward, that is, to drive the drilling assembly 6 to move toward the mold to drill the mold. At the same time, during the drilling process, the protective assembly 7 is set on the outside of the drilling assembly 6 to prevent debris from splashing outward during drilling. By setting the first driving unit 3, the second driving unit 4 and the third driving unit 5, the mold and the drilling assembly 6 can be quickly moved to the designated position, thereby improving work efficiency.

[0024] In this embodiment, the first driving part 3, the second driving part 4 and the third driving part 5 each include a connecting plate 31, a lead screw 32, a first motor 33, a slider 34 and a slide rail 35. Among them, the connecting plate 31 of the first driving part 3 is fixedly arranged on the top surface of the support plate 1, and the connecting plate 31 of the third driving part 5 is erected above the support plate 1. (It should be noted here that two vertically arranged connecting columns (not shown in the figure) are fixedly arranged at intervals on the top surface of the support plate 1. The two ends of the connecting plate 31 of the third driving part 5 are respectively fixedly connected to the two connecting columns. After the two connecting columns and the connecting plate 31 of the third driving part 5 are fixed, they are slightly called a U-shaped structure), and the connecting plate 31 of the second driving part 4 is arranged on one side of the third driving part 5. Each lead screw 32 is respectively rotatably connected to the corresponding connecting plate 31, and the axial direction of the lead screw 32 is parallel to the length direction of the corresponding connecting plate 31. The first motor 33 is arranged at one end of the corresponding lead screw 32 for driving the lead screw 32 to rotate. The slider 34 is sleeved on the lead screw 32 and is screwed to the lead screw 32. There are two slide rails 35, which are respectively located on both sides of the support plate 1 in the width direction. Among them, the supporting component 2, the second driving part 4 and the drilling component 6 are respectively slidably arranged on the corresponding slide rails 35 and are fixedly connected to the corresponding sliders 34.

[0025] Taking the first driving part 3 as an example, during implementation, the first motor 33 drives the lead screw 32 to rotate forward or backward, thereby driving the slider 34 to move along the X-axis direction of the support plate 1. Further, the slider 34 drives the supporting component 2 to move along the X-axis direction of the support plate 1. At the same time, the bottom of the supporting component 2 is slidably connected to the slide rail 35, making the movement of the supporting component 2 more stable.

[0026] The drilling component 6 includes a slide plate 61, a driving motor 62, an electric spindle 63 and a drill bit 64. The slide plate 61 is L-shaped and is slidably connected to the second driving part 4. Specifically, one side of the slide plate 61 is fixedly connected to the slider 34 of the second driving part 4 and is simultaneously slidably connected to the slide rail 35 of the second driving part 4. The driving motor 62 is fixedly arranged on the top surface of the slide plate 61, the electric spindle 63 is arranged on the bottom surface of the slide plate 61, and the output end of the driving motor 62 passes through the slide plate 61 and is connected to the electric spindle 63 for driving the electric spindle 63 to rotate. The drill bit 64 is fixedly arranged at the output end of the electric spindle 63 for drilling the mold.

[0027] In this embodiment, a fixing block 65 is fixedly provided on the bottom surface of the slide plate 61, and the output end of the driving motor 62 is connected to the electric spindle 63 through the fixing block 65, and the protection component 7 is sleeved on the outside of the fixing block 65 and screwed to the fixing block 65. The setting of the fixing block 65 facilitates the disassembly and maintenance of the protection component 7. Among them, the protection component 7 includes a fixed cylinder 71 and a sleeve 72. The fixed cylinder 71 is a circular cylinder with a hollow interior, and the cover is arranged on the outside of the electric spindle 63. The upper part of the fixed cylinder 71 is sleeved on the outside of the fixed block 65 and screwed to the fixed block 65. The bottom end of the fixed cylinder 71 is protruded with a retaining ring 711 in the direction away from the central axis of the fixed cylinder 71. The sleeve 72 is slidably arranged on the outside of the fixed cylinder 71. The sleeve 72 is also a circular cylinder with a hollow interior. The inner diameter of the sleeve 72 is larger than or The outer diameter of the sleeve 72 is equal to the outer diameter of the fixed cylinder 71, and a retaining ring 721 is protruded from the top of the sleeve 72 toward the central axis of the sleeve 72, wherein the inner diameter of the retaining ring 721 is smaller than the outer diameter of the retaining ring 711, so that the sleeve 72 cannot be separated from the fixed cylinder 71 after the sleeve 72 is sleeved with the fixed cylinder 71, and a spring 73 is sleeved on the outer side of the fixed cylinder 71, and the two ends of the spring 73 are respectively in contact with the retaining ring 721 and the bottom surface of the slide plate 61, so as to push the sleeve 72 to move away from the fixed cylinder 71.

[0028] During the implementation, the staff first sleeves the sleeve 72 with the fixed sleeve 71, and then sleeves the spring 73 on the outside of the fixed sleeve 71. At this time, the bottom end of the spring 73 abuts against the outer wall of the retaining ring 721 of the sleeve 72. Then the staff sleeves the fixed sleeve 71 on the outside of the electric spindle 63, and screws the upper part of the fixed sleeve 71 with the fixed block 65, thereby completing the fixing of the protective assembly 7. At this time, the two ends of the spring 73 abut against the bottom surface of the retaining ring 721 and the slide plate 61. When drilling is required, the second driving unit 4 drives the drilling assembly 6 and the protective assembly 7 to move downward. During the drilling process, the protective assembly 7 is always covered on the outside of the drill bit 64 to prevent debris from splashing outward during drilling.

[0029] It should be noted that when drilling, as the drill bit 64 descends, the bottom surface of the sleeve 72 abuts against the mold. As the drill bit 64 continues to descend, the spring 73 is compressed. At this time, the sleeve 72 can move upward along the axial direction of the fixed cylinder 71 without affecting the downward movement of the drill bit 64. When the drilling is completed, the second drive unit 4 drives the drilling assembly 6 to move away from the mold. At this time, the sleeve 72 can be reset due to the elastic force of the spring 73. The protective assembly 7 can prevent debris from splashing outward during drilling. When the drilling is completed, the debris is collected together, which is convenient for the staff to clean up.

[0030] In this embodiment, the supporting assembly 2 includes a receiving tray 21, a receiving plate 22 and a clamping block 23. The receiving tray 21 is used to collect debris generated during the processing. The bottom surface of the receiving tray 21 is fixedly connected to the slider 34 of the first driving part 3, and is also slidably connected to the slide rail 35 of the first driving part 3, that is, the first driving part 3 drives the receiving tray 21 to move along the X-axis direction of the support plate 1. The receiving plate 22 is arranged on the top surface of the receiving tray 21 and is used to receive the mold. That is, during the drilling process, the mold is placed on the receiving plate 22, and a plurality of threaded holes that pass through the receiving plate 22 are arranged. The clamping block 23 is L-shaped. When the mold is placed on the top surface of the receiving plate 22, the clamping block 23 is fixedly connected to the corresponding threaded hole through the first bolt 24.

[0031] During implementation, the mold to be drilled is placed on the receiving plate 22, and the staff presses the clamping block 23 on one side of the mold, and then passes the first bolt 24 through the clamping block 23 and is fixedly connected with the corresponding threaded hole, thereby fixing the mold on the receiving plate 22. By setting multiple threaded holes, molds of different sizes can be accommodated.

[0032] Preferably, through holes that pass through the top and bottom are respectively opened at the four corners of the receiving plate 22, and a second bolt 25 is respectively passed through each through hole. A pad 26 is fixed to the bottom surface of the receiving plate 22 corresponding to each through hole. The bottom end of the second bolt 25 passes through the pad 26 and is screwed to the receiving pan 21. The pad 26 is used to create a gap between the top surfaces of the receiving plate 22 and the receiving pan 21. During the drilling process or the process of cleaning waste chips, some waste chips fall into the threaded holes, and then the waste chips can pass through the threaded holes and fall into the receiving pan 21, avoiding the waste chips from blocking the threaded holes and facilitating centralized cleaning by the staff.

[0033] When the utility model is implemented, the staff places the mold on the receiving plate 22, fixes the mold by the clamping block 23, and then starts the first driving unit 3 to move the mold to the bottom of the drilling assembly 6, and starts the third driving unit 5 to drive the second driving unit 4 to move to the preset position. At this time, the output end of the drilling assembly 6 corresponds to the position where the hole needs to be drilled, and then starts the second driving unit 4 to drive the drilling assembly 6 to move downward to drill the mold. During the drilling process, the protective component 7 can prevent the debris from splashing outward during drilling, which is convenient for the staff to collect the waste chips later. During the collection process, some of the waste chips may fall onto the receiving plate 22 and fall into the receiving tray 21 through the threaded holes on the receiving plate 22, thereby facilitating the staff to collect the waste chips. At the same time, by setting the receiving plate 22, it is also possible to prevent the waste chips from falling into the first driving unit 3, thereby avoiding the waste chips from affecting the first driving unit 3.

[0034] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of 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.
