Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment technology, and in particular to a tooling for processing and fixing a blow molding mold guide plate. Background Technology

[0002] With the accelerating pace of intelligent and precise manufacturing, blow molding technology, with its advantages of high efficiency and low cost, is increasingly widely used in packaging, automotive, and medical device fields. As the core component of blow molding, the precision of the blow mold directly determines the quality and performance of the product. The guide plate, a key component in the blow mold responsible for guiding and positioning, requires extremely high machining precision. Any dimensional deviations or unstable installation can easily lead to problems such as poor mold opening and closing, uneven product wall thickness, and severely impact production efficiency and finished product yield.

[0003] A search revealed Chinese publication number CN218226306U, which discloses a positioning and clamping device for processing mold guide plates, belonging to the field of mold technology. The device includes a base, with an mounting seat installed at the upper end of the base. A clamping block adjustment assembly is installed inside the mounting seat. A clamping block is installed at the upper end of the clamping block adjustment assembly, and a clamping component is installed on the side of the clamping block. This invention improves the convenience and stability of the clamping block adjustment process by incorporating a second slider, a guide rod, and a second mounting groove. This avoids the problem of the clamping block wobbling during sliding. The clamping assembly allows for fine-tuning of the clamping plate via a throttle, thereby improving the clamping plate's fixation effect on the mold guide plate. Furthermore, the assembly incorporates a limit block, a sliding rod, and a spring, which further enhances the fixation effect on the mold guide plate through the spring's restoring action.

[0004] The aforementioned patent specification mentions that "a clamping block adjustment component is provided, which can improve the convenience and stability of the clamping block adjustment process. By providing a second slider, a guide rod, and a second mounting groove, the problem of the clamping block shaking during sliding can be avoided. In addition, the component has a simple structure, is easy to operate, and has a relatively better performance." However, in the above text, the contact area between the clamping block and the guide plate is small, making it difficult to ensure the perpendicularity of the guide plate and affecting the processing effect of the guide plate. In view of the above problems, a blow molding mold guide plate processing and fixing fixture is proposed. Utility Model Content

[0005] The purpose of this application is to provide a tooling for processing and fixing guide plates in blow molding molds, which aims to improve the problem that the contact area between the clamping block and the guide plate is small in some devices, affecting the perpendicularity of the guide plate fixing.

[0006] The technical solution of the blow molding die guide plate processing and fixing fixture provided in this application is as follows: A blow molding die guide plate processing and fixing fixture includes a worktable, a base plate is slidably connected to the top of the worktable, a positioning mechanism is fixedly connected to the top of the base plate, and an installation mechanism is provided inside the worktable; The positioning mechanism includes two positioning columns, the bottoms of which are fixedly connected to the top of the base plate. A positioning block is fixedly connected to the top of each positioning column. A fixing bolt is threaded inside the positioning block. A connecting column is fixedly connected to the outside of the fixing bolt. A rectangular clamping plate is rotatably connected to the outside of the connecting column. A circular plate is fixedly connected to the outside of the connecting column. The outside of the circular plate is rotatably connected to the inside of the rectangular clamping plate. A ball bearing is disposed inside the circular plate. The ball bearing is slidably connected to the inside of the rectangular clamping plate. A guide assembly is fixedly connected to the outside of the positioning block.

[0007] The above technical solution allows the tooling to be adjusted in position via a sliding base plate. The positioning column and positioning block work together to quickly position the guide plate. The rectangular clamping plate is locked with fixing bolts. The circular plate and ball bearings reduce rotational friction. The guiding components improve the movement accuracy. It can be adapted to guide plates of various specifications, improves processing efficiency, enhances fixing stability, reduces operation difficulty, and has a compact structure that is easy to use.

[0008] Preferably, the mounting mechanism includes multiple sliding rods, the outer surfaces of which are slidably connected to the interior of the worktable. An inclined plate is fixedly connected to the bottom of each sliding rod, and the inclined plate is slidably connected to the interior of the worktable. Multiple round rods are slidably connected to the interior of the worktable, with two of the round rods having L-shaped plates fixedly connected to their tops. The bottom of the L-shaped plates contacts the top of the base plate. A spring is sleeved on the outer surface of each round rod, and a sliding assembly is fixedly connected to the bottom of each round rod.

[0009] Through the above technical solution: the sliding rod in the installation mechanism works with the inclined plate to achieve fine height adjustment, the L-shaped plate enhances the fixing effect of the base plate, the sliding component reduces friction and improves the smoothness of adjustment, and the mold guide plate can be quickly installed and removed to ensure stability during processing and improve the convenience of operation and processing accuracy.

[0010] Preferably, the guide assembly includes two connecting blocks, which are externally fixedly connected to the outer sides of the positioning block. A guide rod is slidably connected inside the connecting blocks, and the guide rod is externally fixedly connected to the outer side of the rectangular clamping plate.

[0011] The above technical solution involves a sliding fit between the connecting block and the guide rod in the guide assembly, which restricts the rotational offset of the rectangular clamping plate, enhances clamping stability, ensures accurate positioning of the guide plate, reduces machining errors, improves adjustment smoothness, and has a simple structure that effectively optimizes the positioning effect, enhances the overall reliability of the tooling, and facilitates quick operation.

[0012] Preferably, the sliding assembly includes a bracket, the top of which is fixedly connected to the bottom of the round rod, the outside of which is slidably connected to the inside of the workbench, a pulley is rotatably connected inside the bracket, and the outside of which is slidably connected to the top of the inclined plate.

[0013] Through the above technical solution: the sliding component connects the round rod and the pulley through the bracket. The pulley slides along the inclined plate, converting the vertical force into lateral adjustment, reducing frictional resistance, making the installation mechanism easier to operate, improving adjustment sensitivity and stability, ensuring that the round rod drives the L-shaped plate to be accurately positioned, adapting to different working conditions, simplifying the operation process, enhancing the smoothness of tooling operation, and extending the service life of components.

[0016] Preferably, the workbench has a sliding connection to a limit bar inside, and a pull plate is fixedly connected to the outer side of the limit bar.

[0017] The above technical solution involves a sliding engagement between the limiting crossbar and the worktable, along with a pull plate for easy manual operation. This allows for quick and precise positioning of the base plate, preventing it from shifting during processing, enhancing overall stability, and improving the safety and reliability of the tooling.

[0018] Preferably, the top of the base plate is provided with a positioning groove, and the outer sides of the limiting crossbar are slidably connected to the outer sides of the base plate.

[0019] Through the above technical solution: the positioning groove on the top of the base plate can assist the guide plate in initial alignment, improve clamping efficiency, and the limiting crossbar is slidably connected to both sides of the base plate to form a two-way limiting, enhance the fixing effect of the base plate, prevent lateral displacement during processing, and improve the overall positioning accuracy and ensure processing stability in conjunction with the positioning groove.

[0020] Preferably, an arc-shaped pad is fixedly connected to the top of the positioning groove, and a rubber pad is fixedly connected to the outer side of the rectangular clamping plate.

[0021] Through the above technical solution: the arc-shaped pad at the top of the positioning groove can buffer the impact of placing the guide plate and avoid damage to hard parts; the rubber pad on one side of the rectangular clamp increases the clamping friction, prevents the workpiece from sliding, and protects the surface of the guide plate from scratches, thereby improving clamping stability and workpiece integrity.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the positioning mechanism drives the connecting column and the circular plate to move by rotating the fixing bolt, and the ball bearing pushes the rectangular clamping plate close to the guide plate.

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0030] Example: A tooling for processing and fixing a guide plate in a blow molding die, referring to... Figures 1 to 3 The system includes a workbench 1, which serves as a basic support component. A base plate 2 is slidably connected to the top of the workbench 1. The base plate 2 provides an installation carrier for the positioning mechanism 3. The positioning mechanism 3 is fixedly connected to the top of the base plate 2. An installation mechanism 4 is provided inside the workbench 1. The positioning mechanism 3 includes two positioning columns 31. The positioning columns 31 serve as a support and positioning reference, providing an installation base for the positioning block 32. The bottom of the two positioning columns 31 is fixedly connected to the top of the base plate 2. The top of the positioning columns 31 is fixedly connected to the positioning block 32. The positioning block 32 has a threaded hole inside that mates with the fixing bolt 33 for installing the fixing bolt 33. The fixing bolt 33 is internally threaded and connected to the fixing bolt 33. The fixing bolt 33 can drive the connecting column 34 to rotate by rotating. The connecting column 34 is fixedly connected to the outside of the fixing bolt 33. When the connecting column 34 rotates, it can drive the circular plate 36 to rotate. A rectangular clamping plate 35 is rotatably connected to the outside of the connecting column 34. The rectangular clamping plate 35 is used to directly contact and clamp the blow molding mold guide plate. A circular plate 36 is fixedly connected to the outside of the connecting column 34. The circular plate 36 reduces the friction during rotation by cooperating with the rectangular clamping plate 35 through the ball bearings 37. It can push the rectangular clamping plate 35 to fix the blow molding mold guide plate. The outside of the circular plate 36 is rotatably connected to the inside of the rectangular clamping plate 35. The inside of the circular plate 36 is provided with ball bearings 37. The ball bearings 37 contact the rectangular clamping plate 35 and can push the rectangular clamping plate 35 to move. The outside of the ball bearings 37 is slidably connected to the inside of the rectangular clamping plate 35. A guide assembly 38 is fixedly connected to the outside of the positioning block 32. The guide assembly 38 includes two connecting blocks 381, which provide a sliding mounting base for the guide rod 382. The two connecting blocks 381 are externally fixedly connected to the outer sides of the positioning block 32. The guide rod 382 is slidably connected inside the connecting blocks 381. The guide rod 382 guides the movement of the rectangular clamping plate 35. The guide rod 382 is externally fixedly connected to one side of the rectangular clamping plate 35. Specifically, rotating the fixing bolt 33 of the positioning mechanism 3 causes it to move along the internal thread of the positioning block 32, which drives the connecting column 34 and the circular plate 36 to move. The circular plate 36 pushes the rectangular clamping plate 35 against the guide plate by the ball bearing 37. The guide rod 382 slides in the connecting block 381 to ensure the linear movement of the clamping plate. The clamping plate clamps the guide plate through the rubber pad 9.

[0031] Reference Figure 1 , Figure 2 and Figure 4The installation mechanism 4 includes multiple sliding rods 41. The sliding rods 41 drive the inclined plate 42 to move by sliding. The external parts of the multiple sliding rods 41 are slidably connected to the inside of the worktable 1. The bottom of the sliding rods 41 is fixedly connected to the inclined plate 42. The inclined plate 42 slides by itself and pushes the sliding component 46 with the inclined surface, thereby driving the round rod 43 to move. The external parts of the inclined plate 42 are slidably connected to the inside of the worktable 1. The inside of the worktable 1 is slidably connected to multiple round rods 43. The round rods 43 play the role of transmitting force and driving the L-shaped plate 44 to move. The top of two round rods 43 is fixedly connected to the L-shaped plate 44. The L-shaped plate 44 can move under the drive of the round rods 43. The bottom of the L-shaped plate 44 contacts the top of the base plate 2. The outside of the round rods 43 is fitted with springs 45. The springs 45 provide a restoring force during the installation process, so that the round rods 43 drive the L-shaped plate 44 to fix the base plate 2. The bottom of the round rods 43 is fixedly connected to the sliding component 46. The sliding assembly 46 includes a bracket 461, which connects the round rod 43 and the pulley 462 and transmits motion. The top of the bracket 461 is fixedly connected to the bottom of the round rod 43, and the outside of the bracket 461 is slidably connected to the inside of the worktable 1. The pulley 462 is rotatably connected inside the bracket 461. The pulley 462 converts the linear motion of the inclined plate 42 into the lifting motion of the round rod 43 by rolling in conjunction with the sliding of the inclined plate 42. The outside of the pulley 462 is slidably connected to the top of the inclined plate 42. Specifically, the sliding rod 41 slides inside the workbench 1, causing the bottom inclined plate 42 to slide synchronously. When the inclined plate 42 slides, its inclined surface contacts the pulley 462 and pushes the pulley 462 to roll. The pulley 462 drives the round rod 43 to move through the bracket 461. When the round rod 43 moves, the top L-shaped plate 44 moves with it and separates from the bottom plate 2. At the same time, the spring 45 sleeved on the outside of the round rod 43 will deform due to the movement of the round rod 43. After the external force is removed, the spring 45 returns to its original shape, driving the round rod 43 and the L-shaped plate 44 to reset, completing the fixing operation of the bottom plate 2.

[0032] Reference Figure 1 , Figure 2 and Figure 4The top of the spring 45 is fixedly connected to the inside of the workbench 1, and the bottom of the spring 45 is fixedly connected to the top of the bracket 461. The inside of the workbench 1 is slidably connected to the limit bar 5, which is used to limit the bottom plate 2. The outer side of the limit bar 5 is fixedly connected to the pull plate 6, which allows the operator to pull the limit bar 5 to achieve the limit and release the limit. The top of the bottom plate 2 is provided with a positioning groove 7, which is used to place the rotating part of the plate to be processed. The outer side of the limit bar 5 is slidably connected to the outer sides of the bottom plate 2. The top of the positioning groove 7 is fixedly connected to the arc-shaped pad 8, which plays the role of protecting the mold guide plate. The outer side of the rectangular clamping plate 35 is fixedly connected to the rubber pad 9, which plays the role of anti-slip and protecting the surface of the guide plate when the rubber pad 9 contacts the mold guide plate. Specifically, the rotating shaft of the workpiece to be processed is placed into the positioning groove 7 at the top of the base plate 2, the arc-shaped pad 8 contacts the rotating shaft, the pull plate 6 is pulled, and the limiting crossbar 5 is slid inside the worktable 1 to separate it from the base plate 2. The fixing bolt 33 is rotated, and the rectangular clamping plate 35 moves accordingly. The rubber pad 9 on its outside contacts the mold guide plate. When the bracket 461 moves, the spring 45 is stretched. After the external force disappears, the spring 45 drives the bracket 461 to reset.

[0033] The implementation principle of this application embodiment is as follows: When the blow molding mold guide plate is processed and fixed, the rotating shaft part of the guide plate to be processed is first placed in the positioning groove 7 of the base plate 2, the arc-shaped pad 8 protects the rotating shaft, the fixing bolt 33 is rotated, the fixing bolt 33 moves along the internal thread of the positioning block 32, driving the connecting column 34 and the round plate 36 to move. The round plate 36 can push the rectangular clamping plate 35 closer to the guide plate by cooperating with the ball 37. The rectangular clamping plate 35 drives the guide rod 382 to slide in the connecting block 381, ensuring the linear movement of the rectangular clamping plate 35. The rectangular clamping plate 35 clamps the guide plate with the help of the rubber pad 9. When disassembling the base plate 2, first pull the pull plate 6. The pull plate 6 causes the limiting crossbar 5 to slide, releasing the limiting of the base plate 2. Then slide the sliding rod 41. The sliding rod 41 drives the inclined plate 42 to slide within the worktable 1. The inclined surface of the inclined plate 42 pushes the pulley 462 to roll. The pulley 462 drives the round rod 43 to slide through the bracket 461. The round rod 43 drives the L-shaped plate 44 to move, causing the L-shaped plate 44 to separate from the base plate 2. At the same time, the spring 45 is compressed as the round rod 43 moves. At this time, the base plate 2 can be disassembled. Remove the top of the workbench 1. During installation, place the base plate 2 on the top of the workbench 1 and slide the sliding rod 41 in the opposite direction. The sliding rod 41 drives the inclined plate 42 to move. The pulley 462 rolls on the inclined plate 42, and the spring 45 restores its deformation to generate elastic force. The elastic force pushes the round rod 43 through the bracket 461. The round rod 43 drives the L-shaped plate 44 to fix the base plate 2. The limiting crossbar 5 is inserted into the workbench 1 through the pull plate 6 to assist in limiting the base plate 2, thus completing the installation of the base plate 2.
