[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1-Figure 7 As shown, the problem that the waste falling on the surface of the plastic mold cannot be cleaned up in time and effectively in the prior art can be solved by the following solutions:

[0043] In the present embodiment, a CNC precision drilling device for plastic molds includes a base 1, a fixed platform 11 is movably installed on the top of the base 1, which is used to place the plastic mold and provide a stable support effect for the plastic mold during the drilling process. The top of the base 1 is fixedly connected to a frame 12, and a moving platform 2 is installed on the frame 12. The bottom of the moving platform 2 is slidably connected to a push plate 21, and the bottom of the moving platform 2 is fixedly connected to a slide rail. The push plate 21 is slidably installed on the slide rail. An electric push rod 22 is fixedly connected between the push plate 21 and the moving platform 2. The push plate 21 is driven to move by the electric push rod 22 to realize the sequential operation of the collection component 3 and the drilling component 4. The collection component 3 and the drilling component 4 are arranged on the push plate 21;

[0044] The collecting assembly 3 includes an annular fixing seat 31, and a material blocking collecting cylinder 32 is slidably connected to the bottom of the annular fixing seat 31. By moving the push plate 21, the material blocking collecting cylinder 32 is caused to move downward, so as to achieve full shielding of the area around the drilling point to prevent waste from splashing during the drilling process and keep the surrounding environment clean. A plurality of material blocking auxiliary plates 33 are arranged at the bottom of the material blocking collecting cylinder 32;

[0045] A plurality of material blocking auxiliary plates 33 are distributed in a circular array, forming a circular enclosure structure for the bottom of the material blocking collection cylinder 32, so that after the material blocking collection cylinder 32 moves downward, when the plurality of material blocking auxiliary plates 33 come into contact with the plastic mold with an uneven surface, the mutually cooperating material blocking auxiliary plates 33 can flexibly adapt to the uneven surface of the plastic mold, ensuring a close contact surface with the plastic mold, further enhancing the waste interception effect, and solving the problem of waste leakage caused by the uneven mold surface;

[0046] The drilling assembly 4 includes a rotating disk 41 rotatably connected to the annular fixed seat 31, and a spline sleeve is fixedly connected to the rotating disk 41, a spline shaft 42 is slidably connected in the spline sleeve, and a drill bit fixture 43 is fixedly connected to the bottom of the spline shaft 42. When the spline shaft 42 drives the drill bit fixture 43 to rotate, the spline sleeve 42 drives the rotating disk 41 to rotate, thereby realizing linkage cooperation with the collecting assembly 3.

[0047] A U-shaped frame 34 is fixedly connected to one side of the top of the annular fixing seat 31, and a guide rod 1 is fixedly connected to the inside of the U-shaped frame 34. An oblique guide groove 23 adapted to the guide rod 1 is provided on the push plate 21, and a horizontal guide groove 24 is provided at the bottom of the oblique guide groove 23.

[0048] The electric push rod 22 drives the push plate 21 to move, and guides the guide rod 1 through the oblique guide groove 23 on the push plate 21, so as to cause the material blocking collection cylinder 32 to move downward, and cause several material blocking auxiliary plates 33 to contact the uneven surface of the plastic mold. After that, the guide rod 1 enters the horizontal guide groove 24, which limits the continuous descent of the material blocking collection cylinder 32, and avoids the problem that the material blocking collection cylinder 32 over-extrudes the plastic mold to deform, resulting in reduced drilling accuracy.

[0049] The top two sides of the material-blocking and collecting cylinder 32 are symmetrically fixedly connected with guide rods 35 slidably connected to the annular fixing seat 31, and the bottom of the moving platform 2 is fixedly connected with guide tubes 25 slidably connected to the corresponding guide rods 35. The guide rods 35 provided on the material-blocking and collecting cylinder 32 cooperate with the guide tubes 25 on the moving platform 2 to prevent the pushing plate 21 from synchronously pushing the material-blocking and collecting cylinder 32 to move to a horizontal position during the movement, while not affecting the vertical relative sliding effect between the material-blocking and collecting cylinder 32 and the annular fixing seat 31;

[0050] A suction pipe 36 is fixedly connected to the outer wall of the material blocking collection cylinder 32, and the suction pipe 36 is fixedly connected to a plurality of suction hoppers 37 that penetrate into the interior of the material blocking collection cylinder 32. The suction pipe 36 is connected to an external negative pressure suction device to extract the plastic waste blocked and collected in the material blocking collection cylinder 32 through the suction pipe 36 and the suction hopper 37.

[0051] A piston block 38 is fixedly connected to the top of the material blocking auxiliary plate 33, and a piston cavity 39 adapted to the corresponding piston block 38 is provided at the bottom of the material blocking collecting cylinder 32, and a spring 310 is fixedly connected between the piston cavity 39 and the piston block 38. After the material blocking collecting cylinder 32 moves downward, several material blocking auxiliary plates 33 below the material blocking collecting cylinder 32 contact the uneven surface of the plastic mold, and some of the material blocking auxiliary plates 33 compress the corresponding springs 310, which play a role in autonomously forming the same contact surface according to the uneven surface of the plastic mold, thereby enhancing the waste material interception effect and comprehensively blocking the area around the drilling point. The inner and outer sides of the material blocking collecting cylinder 32 are both threadedly connected with a one-way valve 311 connected to the corresponding piston cavity 39, and an air blowing pipe is installed on the one-way valve 311 located inside the material blocking collecting cylinder 32.

[0052] A U-shaped frame 2 44 is provided on the top of the rotating disk 41, and a guide rod 2 is fixedly connected inside the U-shaped frame 24. An oblique guide groove 26 adapted to the guide rod 2 is provided on the push plate 21, and the oblique guide groove 26 is arranged in parallel with the oblique guide groove 1 23, so that the drill bit can move synchronously downward during the descending process of the material blocking collection cylinder 32. A motor 1 45 for driving the spline shaft 42 to rotate is installed on the bottom bolt of the U-shaped frame 24;

[0053] The electric push rod 1 22 drives the push plate 21 to move, and guides the guide rod 2 through the oblique guide groove 26 on the push plate 21, so that the drill bit and the material blocking collection cylinder 32 are prompted to move downward synchronously, and after the material blocking collection cylinder 32 is restricted to continue to descend, the guide rod 2 continues to move downward under the guidance of the oblique guide groove 26. At this time, the motor 1 45 drives the spline shaft 42 to rotate, and the spline shaft 42 drives the drill clamp 43 to carry the drill bit to rotate for drilling.

[0054] A plurality of L-shaped rods 46 are fixedly connected to the bottom of the rotating disk 41, and a crushing knife 47 is fixedly connected to the L-shaped rods 46. An annular wave groove 312 is provided on the annular inner wall of the material blocking collection cylinder 32, which is slidably connected to the L-shaped rods 46. The sliding of the L-shaped rods 46 in the annular wave groove 312 can avoid the problem of separation of the material blocking collection cylinder 32 and the annular fixing seat 31.

[0055] As the drilling proceeds, filamentary plastic waste is generated, and as the drilling continues, the filamentary plastic waste continues to extend. Combined with the centrifugal force of rotation, the end of the filamentary plastic waste moves away from the drill bit and contacts the top of the material blocking collection tube 32. The spline shaft 42 drives the rotating disk 41 to rotate via the spline sleeve. The rotating disk 41 rotates with multiple crushing knives 47 via the L-shaped rod 46. Combined with the suction hopper 37 to block the filamentary plastic waste, the filamentary plastic waste is crushed, and combined with the external negative pressure suction equipment, efficient collection and treatment of waste is achieved, while also avoiding the problem of filamentary plastic waste easily entangled with the drill bit.

[0056] An electric cylinder slide module 13 is fixedly mounted on the frame 12, a mounting plate 14 is fixedly connected to the electric cylinder slide module 13, and an electric push rod 2 15 is fixedly connected between the mounting plate 14 and the moving platform 2, and a plurality of movable rods slidably connected to the mounting plate 14 are fixedly connected to the top of the moving platform 2 to increase the connection strength between the moving platform 2 and the mounting plate 14. The electric push rod 2 15 is combined with the horizontal movement of the push plate 21 to realize the drilling of plastic molds of different heights and the replacement of the drill bit;

[0057] An electric cylinder slide module 16 is installed between the base 1 and the fixed table 11. The electric cylinder slide module 13 drives the mounting plate 14 to move along the length direction of the base 1, and the electric cylinder slide module 16 drives the fixed table 11 to move along the width direction of the base 1, driving the drill bit to move to just above the designated drilling point of the plastic mold, thereby realizing drilling processing at different positions on the plastic mold.

[0058] A bidirectional screw rod 17 is rotatably connected to the fixed platform 11, and a clamping plate 18 slidably connected to the fixed platform 11 is symmetrically threaded on the bidirectional screw rod 17. A mounting groove is provided on the top of the fixed platform 1, and the bidirectional screw rod 17 is installed in the mounting groove to prevent the setting of the bidirectional screw rod 17 from affecting the stable placement of the plastic mold, and the cross-section of the clamping plate 18 is an inverted mountain-shaped structure, which is used for the stability of the clamping plate 18 during the sliding process. A limit plate 19 is symmetrically provided on one side of the clamping plate 18, and a clamping block 110 is fixedly connected to the limit plate 19. A plurality of clamping grooves 111 adapted to the clamping block 110 are equidistantly provided on the clamping plate 18, and a motor 2 112 for driving the bidirectional screw rod 17 to rotate is bolted to the base 1;

[0059] The distance between the two groups of limit plates 19 on the clamping plate 18 is determined according to the size of the plastic mold, and then the block 110 on the clamping plate 18 is engaged with the slot 111 at the corresponding position, and the plastic mold is placed between the multiple groups of limit plates 19. The motor 2 112 drives the bidirectional screw 17 to rotate, and the bidirectional screw 17 drives the two groups of clamping plates 18 to move relative to each other. Through the two groups of limit plates 19 on the clamping plate 18 and the relative movement of the two groups of clamping plates 18, the positioning and clamping of plastic molds of different sizes are achieved.

[0060] A vertical plate 113 is fixedly connected to one side of the top of the fixed platform 11, and a plurality of drill bit placement seats 114 are fixedly installed at equal intervals on the top of the vertical plate 113. The drill bit placement seat 14 is a rod-shaped structure, and a drill bit placement groove is opened on the top for vertical placement of the drill bit. The height of the drill bit placement seat 14 is higher than the height of the material blocking collection cylinder 32, and cooperates with the electric push rod 15 to drive the material blocking collection cylinder 32 to move downward, so as to realize the drill bit replacement process;

[0061] The electric cylinder slide module 13 drives the mounting plate 14 to move, and moves the drill fixture 43 to the top of the vertical plate 113. The electric cylinder slide module 2 16 drives the fixed platform 11 to move along the width direction of the base 1, so that the required corresponding drill bits on the multiple drill bit placement seats 114 move to the bottom of the drill fixture 43. The electric push rod 2 15 drives the mobile platform 2 to move downward, so that the drill fixture 43 contacts and grabs the corresponding drill bit, and at the same time, it can realize the rapid replacement of drill bits of different models.

[0062] Example 2: Please refer to Figure 5-Figure 8 As shown in the figure, the problem of difficulty in cleaning the waste attached to the drill bit can be solved by the following solutions:

[0063] In this embodiment, a piston block 38 is fixedly connected to the top of the material blocking auxiliary plate 33, a piston cavity 39 adapted to the corresponding piston block 38 is opened at the bottom of the material blocking collection cylinder 32, and a spring 310 is fixedly connected between the piston cavity 39 and the piston block 38, and a one-way valve 311 connected to the corresponding piston cavity 39 is threadedly connected to the inner and outer sides of the material blocking collection cylinder 32, and a blowing pipe is installed on the one-way valve 311 located inside the material blocking collection cylinder 32;

[0064] During the rotation of the rotating disk 41 carrying the L-shaped rod 46, the sliding of the L-shaped rod 46 in the annular wave groove 312 drives the material blocking collection cylinder 32 to reciprocate up and down. When the material blocking collection cylinder 32 moves upward, the compression force of the spring 310 causes the piston block 38 to move downward in the corresponding piston chamber 39. In combination with the one-way valve 311 on the outer side of the material blocking collection cylinder 32, the external air is drawn into the piston chamber 39.

[0065] When the material-blocking and collecting cylinder 32 moves downward, the contact between the material-blocking auxiliary plate 33 and the plastic mold causes the piston block 38 to move upward relatively in the corresponding piston cavity 39. Combined with the one-way valve 311 inside the material-blocking and collecting cylinder 32, the air in the piston cavity 39 is blown into the interior of the material-blocking and collecting cylinder 32 through the air blowing pipe. The piston block 38 continuously slides back and forth in the corresponding piston cavity 39, so as to achieve the effect of continuously blowing air into the interior of the material-blocking and collecting cylinder 32, so as to blow up the waste particles, and assist the negative pressure suction to improve the waste collection effect.

[0066] After the drilling is completed, the electric push rod 22 drives the push plate 21 to reset and move, prompting the drill bit to move upward, and as the motor 45 drives the spline shaft 42 to continue to rotate, the material blocking collection cylinder 32 continues to reciprocate up and down, and with the movement of the piston block 38 in the corresponding piston chamber 39, air is continuously blown into the inside of the material blocking collection cylinder 32 to blow off the waste particles adsorbed on the surface of the drill bit, and then combined with the external negative pressure suction equipment to extract the waste particles in the material blocking collection cylinder 32, complete the comprehensive cleaning of the waste.

[0067] Example 3: Please refer to Figure 1-Figure 8 As shown, the present invention also provides a method for using a plastic mold CNC precision drilling device, comprising the following steps:

[0068] Step 1: Positioning and clamping the plastic mold: Determine the distance between the two groups of limit plates 19 on the clamping plate 18 according to the size of the plastic mold, then engage the clamping block 110 on the clamping plate 18 with the corresponding position of the clamping slot 111, place the plastic mold between the multiple groups of limit plates 19, and the motor 2 112 drives the bidirectional screw 17 to rotate, and the bidirectional screw 17 drives the two groups of clamping plates 18 to move relative to each other, so as to position and clamp the plastic mold;

[0069] Step 2: Drill bit grabbing and replacement: The electric cylinder slide module 13 drives the mounting plate 14 to move along the length direction of the base 1, and moves the drill fixture 43 to the top of the vertical plate 113. The electric cylinder slide module 2 16 drives the fixed platform 11 to move along the width direction of the base 1, so that the required corresponding drill bits on the multiple drill bit placement seats 114 are moved to the bottom of the drill fixture 43. The electric push rod 2 15 drives the moving platform 2 to move downward, so that the drill fixture 43 contacts and grabs the corresponding drill bit, and then drives the drill bit to move to the top of the designated drilling point of the plastic mold through the electric cylinder slide module 13 and the electric cylinder slide module 2 16;

[0070] Step 3: Material blocking and shielding around the drilling point: The electric push rod 1 22 drives the push plate 21 to move, and the oblique guide groove 1 23 and the oblique guide groove 2 26 on the push plate 21 guide the guide rod 1 and the guide rod 2 respectively, so that the material blocking collection cylinder 32 and the drill bit move downward synchronously. During this process, several material blocking auxiliary plates 33 below the material blocking collection cylinder 32 contact the uneven surface of the plastic mold, and the corresponding spring 310 is compressed by the piston block 38, so as to fully block the material around the drilling point;

[0071] Step 4: Drilling and crushing of filamentary plastic waste: the electric push rod 1 22 continuously pushes the push plate 21 to move, the guide rod 1 enters the horizontal guide groove 24, and limits the continuous descent of the material blocking collection tube 32. The guide rod 2 continues to move downward under the guidance of the oblique guide groove 26, and the motor 1 45 drives the spline shaft 42 to rotate, and the spline shaft 42 drives the drill bit fixture 43 to carry the drill bit to rotate for drilling. As the drilling proceeds, the filamentary plastic waste is discharged, and as the filamentary plastic waste continues to extend and under the action of the centrifugal force of the rotation, the end of the filamentary plastic waste contacts the top of the material blocking collection tube 32, and the spline shaft 42 also drives the rotating disk 41 to rotate, and the rotating disk 41 rotates through the L-shaped rod 46 and carries a plurality of crushing knives 47, and combined with the suction hopper 37 to block the filamentary plastic waste, the filamentary plastic waste is crushed;

[0072] Step 5: waste collection: connect the suction pipe 36 to the external negative pressure suction equipment, extract the crushed waste particles in the material blocking collection tube 32 through the suction pipe 36 and the suction hopper 37, and during the rotation of the rotating disk 41 carrying the L-shaped rod 46, combined with the sliding of the L-shaped rod 46 in the annular wave groove 312, drive the material blocking collection tube 32 to reciprocate up and down, and combine the resistance between the material blocking auxiliary plate 33 and the plastic mold, and the compression force of the spring 310, so as to cause the piston block 38 to slide back and forth in the corresponding piston cavity 39, and then combine the one-way valve 311 inside and outside the material blocking collection tube 32 to continuously extract external air and inject it into the interior of the material blocking collection tube 32 to blow up the waste particles, and assist the negative pressure suction to improve the waste collection effect;

[0073] Step 6: Cleaning the waste material on the drill bit surface: After the drilling is completed, the electric push rod 22 drives the push plate 21 to reset and move, prompting the drill bit to move upward, and as the motor 45 drives the spline shaft 42 to continue to rotate, the material blocking collection cylinder 32 continues to reciprocate up and down, and with the movement of the piston block 38 in the corresponding piston chamber 39, air is continuously blown into the inside of the material blocking collection cylinder 32 to blow off the waste particles adsorbed on the drill bit surface, and then combined with the external negative pressure suction equipment to extract the waste particles in the material blocking collection cylinder 32, complete the comprehensive cleaning of the waste.
