Description

Technical Field

[0001] The invention relates to the technical field of mold processing, in particular to a machine tool for processing a bottle blow molding mold and a clamping tool. Background Art

[0002] In modern manufacturing, plastic products are used in various industries, among which bottle products occupy an important position in the packaging field. Blow molding is one of the core technologies for producing bottle products. Usually, bottle blow molding molds are composed of two semicircular hollow molds. In the actual blow molding production process, these two semicircular hollow molds need to be precisely clamped. The quality of the clamping directly determines the quality of the final blow-molded bottle. If the clamping is not tight, during the blow molding process, the plastic material may overflow from the gap, resulting in serious quality problems such as flash and uneven wall thickness on the bottle.

[0003] In order to achieve tight mold closing, the fitting surfaces of the two semicircular hollow molds must be processed. When the mold is processed, the angle needs to be precisely adjusted to ensure that key parts such as the mold closing surface can be accurately processed. However, in actual operation, since the outer wall of the mold is in an arc shape, when the mold is rotated to adjust the processing angle, it is difficult to ensure that the mold is in a stable clamping state during the flipping period. If stable clamping cannot be performed, the accuracy of the processed surface is easily damaged, resulting in deviation of the mold closing surface. Summary of the invention

[0007] The two first-strut rod assemblies are used to press and fix the supporting base plate. When the workpiece is processed horizontally, the two second-strut rod assemblies can press and clamp the two sides of the workpiece. When the workpiece is flipped over by the angle push plate mechanism, one of the second-strut rod assemblies loses support and slides down, applying pressure to the supporting base plate to strengthen it. At the same time, the other second-strut rod assembly is lifted and combined with the angle push plate mechanism to clamp and fix the workpiece.

[0008] As a further improvement of the technical solution, the first support rod assembly includes a first pressing plate and a first branch rod, the first pressing plate is threadedly connected to the upper end of the first branch rod, the bottom end of the first branch rod passes through the middle hole formed between the plate frames and is fixedly installed at the bottom of the bottom cavity, and the bottom end of the first pressing plate is attached to the surface of the supporting bottom plate to apply a clamping force to the supporting bottom plate;

[0009] The second support rod assembly includes a second pressure plate and a second branch rod, the second branch rod includes a hollow rod, the bottom of the hollow rod is fixedly installed at the bottom of the bottom cavity, a movable rod is slidably installed inside the hollow rod, the surface of the movable rod is in contact with the inner wall of the hollow rod, the second pressure plate is fixedly connected to one end of the movable rod away from the hollow rod, an elastic member is fixedly installed at one end of the movable rod away from the second pressure plate, and the other end of the elastic member is fixedly connected to the bottom of the inner cavity of the hollow rod.

[0010] As a further improvement of the present technical solution, the angle push plate mechanism includes two side frame plates, the two side frame plates are symmetrically arranged, and extension rods are movably arranged inside the two side frame plates, the side of the side frame plates and the extension rods are fixed by a swivel, and the two extension rods are located inside the bottom cavity on one side away from the side frame plates, and a connecting rod is fixedly connected between the two extension rods, and the connecting rod is located inside the bottom cavity, and a driving member is arranged inside the bottom cavity, and the driving member includes a vertical plate fixedly installed inside the bottom cavity, a micro screw is rotatably arranged between the vertical plate and the inner wall of the bottom cavity, a driving motor is fixedly installed on the side of the vertical plate away from the micro screw, one end of the micro screw is fixedly connected to the output shaft of the driving motor, and the connecting rod is movably installed on the surface of the micro screw.

[0011] As a further improvement of the technical solution, the two first pressing plates and the two second pressing plates are both installed with bonding plates at one end close to the supporting bottom plate, the four bonding plates are all made of elastic material, and the size of the two second pressing plates is longer than that of the two first pressing plates;

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the bottle blow molding mold processing machine tool and clamping tooling, multiple plate racks divide the workbench into two parts: a support platform and a bottom cavity. A support bottom plate is provided on the surface of the support platform, and the arc-shaped structure on the surface can provide stable support for the arc-shaped mold. When the mold is in a horizontal state, the first support rod assembly and the second support rod assembly arranged on the side of the support bottom plate can clamp the support bottom plate and the mold respectively.

[0016] When the mold needs to be flipped, the angle push plate mechanism can be used to push the mold to flip inside the support base plate. During this process, the second support rod assembly on the lifted side of the mold can rise with the lifting of the mold and continue to clamp the mold. When the other side of the mold is flipped to the inside of the support base plate, the second support rod assembly on this side will descend with the flipping of the mold. When it descends to fit the surface of the support base plate, it will fix and clamp the support base plate, thereby reducing the possibility of sliding of the support base plate.

[0036] The following will be combined with the accompanying drawings in 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. Example

[0037] See also Figure 1 , Figure 2 and Figure 5As shown, the purpose of this embodiment is to provide a clamping tool for a bottle blow molding mold, including a workbench 11 and a supporting base plate 21, the supporting base plate 21 is installed on the surface of the workbench 11, the workbench 11 is a concave structure, and a plurality of plate racks 111 are fixedly installed on one side of the workbench 11 close to the concave opening, and the plurality of plate racks 111 separate the workbench 11 into a supporting platform 15 and a bottom cavity 16, the upper surface of the supporting base plate 21 is semi-arc-shaped, and a first strut assembly 22 and a second strut assembly 23 are arranged on both sides of the supporting base plate 21, and two of the first strut assembly 22 and the second strut assembly 23 are arranged.

[0038] The two first support rod assemblies 22 and the two second support rod assemblies 23 are arranged in a staggered manner, and an angle push plate mechanism 3 is arranged on the side of the support base plate 21 away from the first support rod assemblies 22 and the second support rod assemblies 23 .

[0039] The two first support rod assemblies 22 are used to press and fix the support base plate 21. When the workpiece is processed horizontally, the two second support rod assemblies 23 can press and clamp the two sides of the workpiece. When the workpiece is flipped over by the angle push plate mechanism 3, one of the second support rod assemblies 23 loses support and slides down, applying pressure to the support base plate 21 to strengthen it. At the same time, the other second support rod assembly 23 is lifted and combined with the angle push plate mechanism 3 to clamp and fix the workpiece.

[0040] Since the specifications of the molds processed by the processing machine are different, it is necessary to select an appropriate support base plate 21 according to the arc specifications of the outer wall of the mold. The support base plate 21 is movably installed on the surface of the support platform 15. Therefore, it is necessary to use a first support rod assembly 22 to clamp and fix the support base plate 21. The specific structure of the first support rod assembly 22 is disclosed below. The first support rod assembly 22 includes a first pressure plate 221 and a first branch rod 222. The first pressure plate 221 is threadedly connected to the upper end of the first branch rod 222. The bottom end of the first branch rod 222 passes through the middle hole formed between the plate frames 111 and is fixedly installed at the bottom of the bottom cavity 16. The bottom end of the first pressure plate 221 is attached to the surface of the support base plate 21 to apply a clamping force to the support base plate 21.

[0041] After selecting a suitable support base plate 21, place it on the surface of the support platform 15, and the support base plate 21 needs to be between the two first branch rods 222. Then, the two first pressing plates 221 are rotated and installed on the top of the first branch rods 222 respectively. During the installation process, it is necessary to ensure that the two first pressing plates 221 can effectively press and clamp the support base plate 21, so that the support base plate 21 remains stable on the support platform 15, providing a stable foundation for subsequent processing operations.

[0042] Depend on Figure 5It can be seen that the two first branch rods 222 and the two first pressure plates 221 are installed in an oblique angle symmetrical manner. This installation method enables them to fix the diagonals of the support base plate 21. Unlike the traditional four-corner support method, this oblique angle symmetrical fixed support method can more evenly disperse the stress generated during mold processing. During the mold processing process, the mold will generate stress, and the four-corner support is likely to cause stress concentration at certain points. With the oblique angle symmetrical support method, when the mold is subjected to external force, the stress will be more evenly transmitted to the surroundings along these oblique support structures. This oblique support distribution changes the path of stress transmission, so that the stress is no longer concentrated on a few points like the four-corner support, but is dispersed to a larger area, effectively avoiding the problems that may be caused by stress concentration, thereby ensuring the quality and accuracy of mold processing, and further improving the stability and reliability of the entire processing process.

[0043] It should be noted that the interior of the support base plate 21 is a counterweight structure, which can enhance the supporting effect on the mold.

[0044] After the mold is placed inside the supporting bottom plate 21, the mold needs to be clamped again with the help of the second support rod assembly 23. The specific structure of the second support rod assembly 23 is disclosed below. The second support rod assembly 23 includes a second pressing plate 231 and a second branch rod 232. The second branch rod 232 includes a hollow rod 2321. The bottom of the hollow rod 2321 is fixedly installed at the bottom of the bottom cavity 16. A movable rod 2322 is slidably installed inside the hollow rod 2321. The surface of the movable rod 2322 is in contact with the inner wall of the hollow rod 2321.

[0045] The second pressing plate 231 is fixedly connected to one end of the movable rod 2322 away from the hollow rod 2321 . An elastic member 2323 is fixedly installed on one end of the movable rod 2322 away from the second pressing plate 231 . The other end of the elastic member 2323 is fixedly connected to the bottom of the inner cavity of the hollow rod 2321 .

[0046] See also Figure 7 and Figure 8 As shown, when the mold needs to be placed and fixed, the staff pulls the two second pressure plates 231 at the same time, driving the two movable rods 2322 to slide simultaneously inside the hollow rod 2321, thereby forcing the two second branch rods 232 to lift. Then, another staff member places the mold to be processed horizontally and fits inside the supporting bottom plate 21. After the placement is completed, the two second pressure plates 231 are released. At this time, the movable rod 2322 will slide inside the hollow rod 2321 under the action of the elastic member 2323. When the two second pressure plates 231 are fit and supported on the surface of the mold, the mold is installed. At this time, the two second pressure plates 231 can provide good support for both sides of the mold to ensure that the mold remains stable during horizontal processing.

[0047] The function of the above-mentioned elastic member 2323 is that when the second pressure plate 231 is pulled, the movable rod 2322 will be driven to slide up in the hollow rod 2321. This process will exert a force on the elastic member 2323 to cause it to deform. After the second pressure plate 231 is released, the elastic member 2323 uses its own elastic restoring force to cause the movable rod 2322 to slide down in the hollow rod 2321. The above-mentioned elastic member 2323 preferably uses a spiral spring member, which has a high elastic limit and a certain impact toughness, can withstand repeated expansion and contraction deformation, and ensure long-term stable operation.

[0048] When the mold needs to be flipped, the mold needs to be pushed and flipped by the angle push plate mechanism 3. The specific structure of the angle push plate mechanism 3 is disclosed below. The angle push plate mechanism 3 includes two side frame plates 31, and the two side frame plates 31 are symmetrically arranged. Extension rods 32 are movably arranged inside the two side frame plates 31. The side frame plates 31 and the extension rods 32 are fixed by a swivel 33. The two extension rods 32 are located inside the bottom cavity 16 on the side away from the side frame plates 31. A connecting rod 34 is fixedly connected between the two extension rods 32. The connecting rod 34 is located inside the bottom cavity 16, and a driving member 35 is arranged inside the bottom cavity 16.

[0049] The driving member 35 includes a vertical plate 352 fixedly installed inside the bottom cavity 16, a micro screw 351 is rotatably arranged between the vertical plate 352 and the inner wall of the bottom cavity 16, a driving motor 353 is fixedly installed on the side of the vertical plate 352 away from the micro screw 351, one end of the micro screw 351 is fixedly connected to the output shaft of the driving motor 353, and a connecting rod 34 is movably installed on the surface of the micro screw 351.

[0050] See also Figure 5 , Fig. 9 Combined with Fig.10 As shown, when the mold needs to be flipped to one side, the drive motor 353 is started, and the output shaft of the drive motor 353 will drive the micro screw 351 fixedly connected to it to rotate. During the rotation of the micro screw 351, the connecting rod 34 engaged with its surface will slide in the bottom cavity 16, and the sliding of the connecting rod 34 can prompt the two extension rods 32 and the side frame plates 31 fixedly connected on the top of both sides to slide horizontally. Since the arc surface of the mold is in a fit state with the surface of the supporting bottom plate 21, the mold can be rotated and flipped inside the supporting bottom plate 21 under the push of the side frame plates 31 to achieve angle adjustment of the mold.

[0051] In order to make it more convenient for the side frame plate 31 to flip the mold, the side frame plate 31 and the extension rod 32 are movably connected. Specifically, the side frame plate 31 is connected to the thread on the surface of the extension rod 32 through a swivel ring 33, so that the side frame plate 31 is clamped on the surface of the extension rod 32. The height of the side frame plate 31 can be flexibly adjusted according to the actual situation of the mold to be processed. The side frame plate 31 needs to be higher than the height of the mold in a horizontal state. When the side frame plate 31 is higher than the mold, the point of action of the force applied by the side frame plate 31 on the mold is relatively high. According to the principle of leverage, the farther the point of action of the force is from the center of rotation, the mold and the supporting bottom plate 21 can be approximately regarded as the center of rotation. Under the action of the same magnitude of force, the greater the torque generated, which makes it easier to overcome the inertia and friction of the mold and make the mold start to flip.

[0052] Furthermore, the two side frame plates 31 slide in the same direction. When one of the side frame plates 31 applies a thrust to the mold to cause it to flip, the other side frame plate 31 will move away from the mold, thereby avoiding interference with the flipping process of the mold and ensuring smooth flipping of the mold.

[0053] See also Figure 3 and Figure 4 As shown, during the mold flipping process, the second pressure plate 231 on the lifted side can rise along with the lifting of the mold. This process will pull the movable rod 2322, thereby forcing the elastic member 2323 to stretch. In this state, the second pressure plate 231 on the lifted side of the mold can still maintain the clamping state of the mold. At the same time, the other side of the mold flips to the inside of the supporting bottom plate 21. The second pressure plate 231 on this side loses the support of the mold, and the elastic member 2323 begins to rebound, driving the movable rod 2322 to slide down. In this way, the second pressure plate 231 on this side will also slide down until it is attached to the surface of the supporting bottom plate 21. At this time, the second pressure plate 231 on this side will apply pressure to the supporting bottom plate 21 in the opposite direction of the mold push, thereby effectively reducing the situation where the supporting bottom plate 21 slides with the mold, thereby ensuring the stability and accuracy of the mold flipping operation.

[0054] During the mold flipping process, the side frame plate 31 that pushes the mold cooperates with the second pressure plate 231 at one end of the lift to provide symmetrical support for the mold on both sides. At the same time, the double-sided support effectively disperses the external force borne by the mold, avoids excessive stress concentration in one place, and reduces the risk of damage to the mold during the flipping process.

[0055] The mold workpiece is in a semicircular state. Its special shape determines its stability during the flipping process. When flipping 90 degrees, due to the uneven distribution of its center of gravity, after flipping to a certain angle, the center of gravity of the mold workpiece will exceed the range of the support point. This imbalance of the center of gravity will cause the mold workpiece to lose balance and fall over. Therefore, when the mold workpiece starts to flip, the connecting rod 34 will move with the relevant driving device. See Figure 6 and Fig. 9 As shown, the lower end of the second branch rod 232 is inside the bottom cavity 16. When the connecting rod 34 moves to a certain position, it will be blocked by the second branch rod 232. This blocking effect limits the connecting rod 34 from continuing to move in the original direction. Because the movement of the connecting rod 34 is directly related to the flipping angle of the workpiece, its movement amount and direction determine the flipping degree of the workpiece. Therefore, by limiting the moving position of the connecting rod 34 by the second branch rod 232, the flipping angle of the workpiece can be accurately controlled to avoid it from unbalanced and tipping due to excessive flipping, ensuring that the workpiece is flipped within a safe and stable angle range.

[0056] During the mold processing, it is necessary to ensure that the first pressing plate 221 and the second pressing plate 231 can function effectively while not having a negative impact on the workpiece and related components. Therefore, the two first pressing plates 221 and the two second pressing plates 231 are each installed with a bonding plate 4 at one end close to the supporting base plate 21, and the four bonding plates 4 are all made of elastic material.

[0057] The improvement lies in that: when the second pressure plate 231 slides, due to the elasticity of the bonding plate 4, it can adaptively change its shape and will not cause scratches, collisions and other damages to the workpiece. For the first pressure plate 221, the elastic bonding plate 4 can better contact with the supporting base plate 21, and its elasticity can fill some tiny gaps, increasing the contact area, thereby increasing the friction force, thereby enhancing the clamping effect of the first pressure plate 221 on the supporting base plate 21, ensuring the smooth progress of the mold processing, wherein the bonding plate 4 can be made of rubber material.

[0058] Since the workpiece needs to be flipped during the mold processing, its position will change, and stable clamping is required during flipping to ensure normal processing. Therefore, the size of the two second pressing plates 231 is longer than the size of the two first pressing plates 221.

[0059] The improvement is: Figure 5 As shown, the main function of the second pressure plate 231 is to clamp the workpiece. When the workpiece is flipped and its position changes, only the second pressure plate 231 with a longer size can achieve stable clamping, reduce the problems of shaking and displacement of the workpiece, and ensure that the processing accuracy and quality are not affected.

[0060] During the mold processing, the stable sliding of the angle push plate mechanism 3 is crucial to the precise flipping and processing quality of the mold, and its unstable sliding may lead to problems such as mold flipping angle deviation. Therefore, two limit grooves 52 are provided at the bottom of the bottom cavity 16, and the inner walls of the limit grooves 52 are fitted with the outer walls of the extension rod 32. Side grooves 51 are provided on the inner walls of the two limit grooves 52. The lower end surfaces of the two extension rods 32 are fixedly installed with square plates 5, and the surfaces of the square plates 5 are fitted with the inner walls of the side grooves 51.

[0061] The improvements are: See Figure 7 and Figure 8 As shown, two limiting grooves 52 are provided at the bottom of the bottom cavity 16, and the inner walls of the limiting grooves 52 are fitted with the outer walls of the extension rod 32, which can limit the shaking of the extension rod 32 in the horizontal direction, and each limiting groove 52 has a side groove 51 on the inner wall, and the square plate 5 at the lower end of the extension rod 32 is fitted with the inner wall of the side groove 51, which can limit the movement of the extension rod 32 in the vertical direction, and ensure that the extension rod 32 can only slide stably in the predetermined direction from both the horizontal and vertical directions, thereby ensuring the sliding stability of the angle push plate mechanism 3.

[0062] On the other hand, the present invention also proposes a bottle blow molding mold processing machine tool, which is used to cooperate with the clamping tooling of the above-mentioned bottle blow molding mold to process the bottle blow molding mold, including a base cabinet 12, a workbench 11 fixedly installed on the top of the base cabinet 12, a frame baffle 13 fixedly installed on the outer wall of the workbench 11, a processing head group 14 is installed inside the frame baffle 13, and the processing head group 14 is located on the top of the workbench 11.

[0063] In summary, the working principle of the present solution is as follows: first, select an appropriate support base plate 21 according to the arc specifications of the outer wall of the mold. After selecting a suitable support base plate 21, place it on the surface of the support platform 15, and the support base plate 21 must be between the two first branch rods 222. Then, the two first pressure plates 221 are rotated and installed on the top of the first branch rods 222 respectively. During the installation process, it is necessary to ensure that the two first pressure plates 221 can effectively press and clamp the support base plate 21, so that the support base plate 21 remains stable on the support platform 15.

[0064] When the mold needs to be placed and fixed, the staff pulls the two second pressure plates 231 at the same time, driving the two movable rods 2322 to slide simultaneously inside the hollow rod 2321, thereby forcing the two second branch rods 232 to rise. Then, another staff member places the mold to be processed horizontally and fits inside the supporting bottom plate 21. After the placement is completed, the two second pressure plates 231 are released. At this time, the movable rod 2322 will slide inside the hollow rod 2321 under the action of the elastic member 2323. When the two second pressure plates 231 are fit and supported on the surface of the mold, the mold is installed. At this time, the two second pressure plates 231 can provide good support for both sides of the mold to ensure that the mold remains stable during horizontal processing.

[0065] When the mold needs to flip to one side, the drive motor 353 is started, and the output shaft of the drive motor 353 will drive the micro screw 351 fixedly connected to it to rotate. During the rotation of the micro screw 351, the connecting rod 34 engaged with its surface will slide in the bottom cavity 16, and the sliding of the connecting rod 34 can prompt the two extension rods 32 and the side frame plates 31 fixedly connected on the top of both sides to slide horizontally. Since the arc surface of the mold is in a fit state with the surface of the supporting bottom plate 21, the mold can be rotated and flipped inside the supporting bottom plate 21 under the push of the side frame plates 31 to achieve the angle adjustment of the mold. During the flipping process of the mold, the second pressing plate 231 on the lifted side can rise with the lifting of the mold. A process will pull the movable rod 2322, thereby forcing the elastic member 2323 to stretch. In this state, the second pressure plate 231 on the side of the mold lifting can still maintain the clamping state of the mold. At the same time, the other side of the mold is flipped to the inside of the supporting bottom plate 21. The second pressure plate 231 on this side loses the support of the mold, and the elastic member 2323 begins to rebound, driving the movable rod 2322 to slide down. In this way, the second pressure plate 231 on this side will also slide down until it is attached to the surface of the supporting bottom plate 21. At this time, the second pressure plate 231 on this side will apply pressure to the supporting bottom plate 21 in the opposite direction of the mold push, thereby effectively reducing the situation where the supporting bottom plate 21 slides with the mold, ensuring the stability and accuracy of the mold flipping operation.

[0066] During the mold flipping process, the side frame plate 31 that pushes the mold cooperates with the second pressure plate 231 at one end of the lift to provide symmetrical support for the mold on both sides. At the same time, the bilateral support effectively disperses the external force borne by the mold, avoids excessive stress concentration in one place, reduces the risk of damage to the mold during the flipping process, and ensures that the mold is stably supported during the angle adjustment process.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention.
