Description

Technical Field

[0001] This utility model relates to the field of mold component processing technology, specifically to a hole-opening device for mold components. Background Technology

[0002] Drilling is a common and critical process in the manufacturing of mold components. However, existing drilling devices for mold components have many problems in practical applications, which seriously affect the efficiency and quality of the manufacturing process.

[0003] Currently, most hole-opening devices are ineffective at securing mold components. Traditional fixing methods often only provide simple fixation in certain directions, failing to achieve comprehensive and stable clamping. For example, some devices can only fix the left and right sides of the component, while during the hole-opening process, the component is prone to displacement in the front-to-back direction, leading to inaccurate hole positioning and affecting the precision and subsequent performance of the mold component. Furthermore, after the hole-opening operation is completed, the component needs to be manually removed from the fixing device, which is cumbersome, time-consuming, and affects processing efficiency, causing inconvenience to users.

[0004] In summary, existing mold component opening devices have significant shortcomings in terms of fixing effect and ease of loading and unloading. There is an urgent need for an innovative opening device to solve these problems and improve the efficiency and quality of mold component processing. Utility Model Content

A detachable drill bit is fixedly connected to the output end of the drilling motor.

[0007] As a preferred embodiment of this utility model, a square groove is provided in the center of the base plate, located below the pressure moving plate and the moving clamping plate, and a number of evenly distributed guide rollers are rotatably connected inside the square groove, and the surface of the guide rollers is provided with a smooth and wear-resistant coating.

The inner wall of the sliding sleeve is slidably connected to the surface of the support column.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes a combination structure of a hollow sleeve, a movable retractable rod, and a compression spring. The accessory requiring an opening is placed between a pressure-bearing movable plate and a movable clamping plate. The movable clamping plate pushes the accessory, causing the pressure-bearing movable plate to move to the left. The compression spring is compressed, and the first electric telescopic rod continuously applies tension to the movable clamping plate, clamping and fixing the accessory on both sides. Simultaneously, the follower clamping plates on the front and rear sides of the pressure-bearing movable plate, hinged by torsion springs, can rotate inwards when the pressure-bearing movable plate moves to the left, clamping the accessory on both sides. This achieves comprehensive fixation of the accessory, improves the fixing effect, and effectively prevents the accessory from slipping. Displacement occurs during the drilling process, ensuring the accuracy of the drilling; the second electric telescopic rod on the top plate drives the lifting platform and drilling motor to move up and down, adjusting the drilling height; the guide rails and electric slides inside the support frame allow the drilling motor to move laterally, facilitating drilling operations at different positions of the parts, improving the flexibility and applicability of the device; moreover, after drilling is completed, the first electric telescopic rod retracts, and the pressure-bearing moving plate moves to the right under the rebound pressure of the compression spring, pushing out the parts. The two follow-up side clamps open under the torsion force of the torsion spring, making it convenient for operators to retrieve the parts and improving work efficiency.

[0013] 2. This utility model features a square groove in the center of the base plate with longitudinally arranged guide rollers. This layout facilitates the left-right movement of mold components. In actual operation, when placing the component requiring a hole between the pressure moving plate and the moving clamping plate for fixation, or when removing the component from the device after hole drilling, the longitudinally arranged guide rollers provide a smooth movement path for the component. Since the guide rollers are arranged longitudinally, their rolling direction is consistent with the left-right movement direction of the component, effectively reducing the friction between the bottom of the component and the base plate. This makes the placement and removal of the component easier and more convenient, improving operational efficiency and preventing wear on the bottom of the component due to excessive friction, thus ensuring the surface quality of the component. In addition, the smooth and wear-resistant coating on the surface of the guide rollers further reduces the coefficient of friction with the component, while enhancing the wear resistance of the guide rollers themselves and extending their service life. This ensures that they can stably play a role in reducing friction and facilitating movement during long-term use, thereby improving the practicality and reliability of the entire mold component hole drilling device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4As shown, the present invention provides a mold accessory opening device, including a base plate 1. A fixing plate 2 is fixedly connected to the left side of the top of the base plate 1. A hollow sleeve 3 is fixedly connected to the lower right side of the fixing plate 2. A movable retractable rod 4 is slidably connected inside the hollow sleeve 3. The movable retractable rod 4 is in an extended state. A pressure-bearing movable plate 5 is fixedly connected to the right end of the movable retractable rod 4. A compression spring 6 is sleeved on the surface of the hollow sleeve 3 and the movable retractable rod 4. The left end of the compression spring 6 is fixedly connected to the right side of the fixing plate 2, and the right end of the compression spring 6 is fixedly connected to the left side of the pressure-bearing movable plate 5. The compression spring 6 is in an extended state. Follower side clamps 7 are hinged to the front and rear sides of the pressure-bearing movable plate 5 by torsion springs. In the natural state, the two follower side clamps 7 are in an open state and are symmetrically arranged. Several threaded holes are opened on the front and rear sides of the top of the base plate 1, located outside the follower side clamps 7, and the threaded holes are open to the right. The internal threads of the threaded holes are... The bearing seat is connected to the bearing housing, and the top of the bearing housing is rotatably connected to the limit post 8. The surface of the limit post 8 is in contact with the outer surface of the left end of the follower side clamping plate 7. The right side of the top of the base plate 1 is fixedly connected to the first electric telescopic rod 9. The output end of the first electric telescopic rod 9 is fixedly connected to the moving clamping plate 10 corresponding to the pressure moving plate 5. The four corners of the top of the base plate 1 are fixedly connected to the support column 11. The top end of the support column 11 is fixedly connected to the top plate 12. The center of the top plate 12 is fixedly connected to the second electric telescopic rod 13. The bottom end of the second electric telescopic rod 13 is fixedly connected to the lifting platform 14. The bottom of the lifting platform 14 is fixedly connected to the bearing frame 15. The front and rear sides of the bearing frame 15 are fixedly connected to the horizontally arranged guide rails 16. The surface of the guide rail 16 is slidably connected to the electric slide table 17. The bottom of the electric slide table 17 is fixedly connected to the drilling motor 18 through the connecting frame. The output end of the drilling motor 18 is fixedly connected to the detachable drill bit through the coupling.

[0018] refer to Figure 3 The base plate 1 has a square groove in the center located below the pressure moving plate 5 and the moving clamping plate 10. The interior of the square groove is connected by a rotating shaft to several evenly distributed guide rollers 19. The surface of the guide rollers 19 is provided with a smooth and wear-resistant coating.

[0019] As a technical optimization of this utility model, by opening a square groove in the center of the base plate 1 and arranging guide rollers 19 longitudinally, this layout facilitates the left and right movement of the mold parts. In actual operation, when the parts that need to be drilled are placed and fixed between the pressure moving plate 5 and the moving clamping plate 10, or when the parts are removed from the device after drilling, the longitudinally arranged guide rollers 19 can provide a smooth movement path for the parts. Since the guide rollers 19 are arranged longitudinally, their rolling direction is consistent with the left and right movement direction of the parts, which can effectively reduce the friction between the bottom of the parts and the base plate 1, making the placement and removal of the parts easier and more convenient, improving the efficiency of operation, and avoiding wear on the bottom of the parts due to excessive friction, thus ensuring the surface quality of the parts. In addition, the smooth and wear-resistant coating on the surface of the guide rollers 19 further reduces the coefficient of friction with the parts, while enhancing the wear resistance of the guide rollers 19 themselves, extending their service life, and ensuring that they can stably play the role of reducing friction and facilitating movement during long-term use, thereby improving the practicality and reliability of the entire mold part drilling device.

[0020] refer to Figure 2 and Figure 4 A silicone sleeve 20 is fixedly connected to the surface of the limiting post 8. The surface of the silicone sleeve 20 is in contact with the outer surface of the follower side clamp 7. Several evenly distributed rubber convex strips 21 are fixedly connected to the inner surface of the follower side clamp 7.

[0021] As a technical optimization of this utility model, the silicone sleeve 20 on the surface of the limiting post 8 and the rubber protrusion 21 on the inner surface of the follower side clamp 7 both have a positive effect on improving the performance of the device. The silicone sleeve 20 is soft and has a certain degree of elasticity. When the follower side clamp 7 is in contact with the surface of the limiting post 8, the silicone sleeve 20 can increase the friction between the two, making the position of the follower side clamp 7 more stable and better clamping the parts. At the same time, the silicone sleeve 20 can also play a buffering role, reducing the collision and wear between the follower side clamp 7 and the limiting post 8. The rubber protrusion 21 on the inner surface of the follower side clamp 7 can increase the friction with the surface of the parts, further improving the clamping force on the front and rear sides of the parts, ensuring that the parts will not be displaced in the front and rear directions during the drilling process, and improving the accuracy and quality of drilling.

[0022] refer to Figure 3 The top of the fixed plate 2 has round holes on both the front and back sides, and the first stabilizing rod 22 is slidably connected inside the round holes. The right end of the first stabilizing rod 22 is fixedly connected to the left side of the pressure-bearing moving plate 5. The right side of the moving clamp 10 has a second stabilizing rod 23 fixedly connected to both the front and back sides. The surface of the second stabilizing rod 23 is slidably connected to a stabilizing seat 24. The bottom of the stabilizing seat 24 is fixedly connected to the top of the base plate 1.

[0023] As a technical optimization of this utility model, the stability of the device is enhanced by setting a first stabilizing rod 22 on the top of the fixed plate 2, a second stabilizing rod 23 on the right side of the movable clamping plate 10, and a stabilizing seat 24. The first stabilizing rod 22 plays a guiding and stabilizing role when the pressure-bearing movable plate 5 moves left and right, preventing the pressure-bearing movable plate 5 from shaking or shifting during the movement, and ensuring the accuracy of clamping the left and right sides of the accessory. The cooperation of the second stabilizing rod 23 and the stabilizing seat 24 makes the movable clamping plate 10 more stable during the movement, avoiding the impact of the movable clamping plate 10 shaking on the fixing effect of the accessory. Through the setting of these stabilizing structures, the entire hole-opening device is more stable and reliable during operation, improving the accuracy and safety of hole-opening operation.

[0024] refer to Figure 1 and Figure 2 A buffer pad 25 is fixedly connected to the right side of the pressure-bearing movable plate 5, and a wear-resistant and anti-slip pad 26 is fixedly connected to the left side of the movable clamping plate 10.

[0025] As a technical optimization of this utility model, the buffer pad 25 can buffer the impact when the moving clamp 10 pushes the accessory into contact with the pressure moving plate 5, reducing the impact force between the two and avoiding damage to the surface of the accessory, thus ensuring the appearance quality of the accessory. The wear-resistant and anti-slip pad 26 increases the friction between the moving clamp 10 and the accessory, improves the clamping force on the accessory, and prevents the accessory from sliding left and right during the opening process. At the same time, the wear resistance of the wear-resistant and anti-slip pad 26 can extend its service life, reduce the frequency of replacement due to wear, and reduce the cost of use.

[0026] refer to Figure 1 The lifting platform 14 has round grooves at all four corners, and a sliding sleeve 27 is fixedly connected inside the round groove. The inner wall of the sliding sleeve 27 is slidably connected to the surface of the support column 11.

[0027] As a technical optimization of this utility model, the sliding sleeves 27 at the four corners of the lifting platform 14 cooperate with the support column 11, which plays a key stabilizing role in the movement of the lifting platform 14. The sliding sleeves 27 can slide smoothly on the surface of the support column 11, making the lifting platform 14 move up and down more smoothly under the drive of the second electric telescopic rod 13, avoiding the lifting platform 14 from shaking or tilting, ensuring the stability of the drilling motor 18 during the up and down movement, thereby improving the precision and accuracy of drilling. At the same time, the cooperation between the sliding sleeves 27 and the support column 11 can also reduce the friction during the movement of the lifting platform 14, making the movement of the lifting platform 14 smoother and improving the operating efficiency of the device.

[0028] The working principle and usage process of this utility model are as follows: In use, the mold component requiring drilling is placed between the pressure-bearing moving plate 5 and the moving clamping plate 10. At this time, the longitudinally arranged guide rollers 19 reduce friction at the bottom of the component, facilitating its left and right movement to a suitable position. Next, the first electric telescopic rod 9 is activated, its output end pushing the moving clamping plate 10 to the left. The moving clamping plate 10 pushes the component to the left, causing the pressure-bearing moving plate 5 to move to the left, compressing the compression spring 6, thereby clamping the left and right sides of the component. Simultaneously, as the pressure-bearing moving plate 5 moves to the left, it causes the two follower-side clamping plates 7 to move inwards under the restriction of the limiting posts 8, clamping the front and rear sides of the component and securing it securely from all directions. Furthermore, depending on the size of the component, the limiting posts 8 can be fixed inside different threaded holes, changing their distance from the follower-side clamping plates 7. The closing size of the follower side clamp 7 is adjusted to match the size of the accessory. Then, the second electric telescopic rod 13 in the center of the top plate 12 is activated, causing the lifting platform 14 to lower the support frame 15 and the drilling motor 18 to a suitable drilling height. The lateral position of the drilling motor 18 is then adjusted by the electric slide 17 on the guide rail 16, and the drill bit is aligned with the position where the hole needs to be opened. The drilling motor 18 is then started to begin the hole-opening operation on the accessory. After the hole is opened, the first electric telescopic rod 9 is controlled to retract, and the pressure-bearing moving plate 5 is pushed out by the return pressure of the compression spring 6. The two follower side clamps 7 are opened relative to each other by the return torque of the torsion spring, releasing the fixation of the accessory and making it easier for the operator to retrieve the accessory, thus completing one hole-opening operation. After the work is completed, the residual iron filings on the surface of the device are cleaned in time to prevent iron filings from entering the gaps of various components and affecting the normal use of the device.
