DETAILED DESCRIPTION

[0025] The technical scheme of the utility model will be further specifically described below by specific embodiments, and the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Embodiment 1: refer to Figures 1 to 4 A kind of injection molding machine mold locking oil cylinder support rotating device, this embodiment introduces a kind of injection molding machine mold locking oil cylinder support rotating device in detail, the device has important application value in injection molding machine field, can effectively improve the production efficiency and product quality of injection molding machine, its unique structure design makes it show many advantages in actual operation.

[0027] The injection molding machine mold locking oil cylinder support rotating device is mainly composed of a main support rod 3 and an outer support 4. The outer support 4 is in a surrounding shape, tightly enclosing the main support rod 3, forming a relatively stable external frame structure. There is a specific gap 23 between the outer support 4 and the main support rod 3, which is not a simple gap, but has a key functional layout. In the gap 23, a rotating shaft 2 is symmetrically arranged. This symmetrical layout enables the entire device to maintain good balance during stress and operation. One end of the rotating shaft 2 is a support column 21, which has good support performance and can rotate flexibly in the gap 23 along with the rotating shaft 2. The flexibility of this rotation provides convenience for the operation of the mold locking oil cylinder 1. The other end of the rotating shaft 2 is a side positioning rod 22, which cooperates with the center positioning rod 32 at the top of the main support rod 3 to jointly fix the mold locking oil cylinder 1. Through the cooperation of the side positioning rod 22 and the center positioning rod 32, the mold locking oil cylinder 1 can be stably fixed on the device, avoiding product quality problems caused by cylinder shaking during assembly.

[0028] From the overall structure, the injection molding machine mold locking oil cylinder support rotating device adopts a mechanical structure support, which is one of the important features that distinguishes it from traditional devices. Mechanical structure support has the advantages of high stability and strong durability. In actual production, the diameter of the mold locking oil cylinder 1 may vary due to different production needs, and this device can automatically adjust to effectively support mold locking oil cylinders 1 of different diameters. This automatic adjustment function is mainly due to the ingenious structure design, the rotation of the rotating shaft 2, and the cooperation of the side positioning rod 22 and the center positioning rod 32, which allows the device to adjust itself according to the diameter of the mold locking oil cylinder 1, ensuring the stability and accuracy of the oil cylinder in the support state. At the same time, the device also ensures that the mold locking oil cylinder 1 can rotate, which is of great significance to the production process of the injection molding machine. During the injection molding process, the mold locking oil cylinder 1 needs to be adjusted accordingly according to the position and shape of the mold, so that the plastic raw materials can be uniformly injected into the mold, thereby improving the quality and production efficiency of the products.

[0029] The side positioning rod 22 is in a curved shape, which not only increases its own strength and stability, but also better adapts to the shape and position of the mold locking oil cylinder 1. A plurality of support bearings 5 are arranged side by side on the side positioning rod 22. The arrangement of the support bearings 5 allows the side positioning rod 22 to more stably withstand the pressure of the oil cylinder during the fixation of the mold locking oil cylinder 1, reduces friction, and prolongs the service life of the device. At the same time, these support bearings 5 can also automatically adjust their positions with the rotation of the mold locking oil cylinder 1, further ensuring the flexibility and stability of the oil cylinder rotation.

[0030] Corresponding to the side positioning rod 22 is the center positioning rod 32, which is also provided with a plurality of support bearings 5. These support bearings 5 cooperate with the support bearings 5 on the side positioning rod 22 to collectively provide all-around support and protection for the mold locking cylinder 1. When the mold locking cylinder 1 is fixed on the device, the support bearings 5 on the center positioning rod 32 can effectively disperse the pressure of the cylinder, avoiding deformation or damage of the cylinder due to excessive local pressure. At the same time, these support bearings 5 can also reduce the friction between the cylinder and the center positioning rod 32, ensuring the smoothness of the cylinder during rotation.

[0031] The outer support 4 includes a support bottom block 42 and a support inclined block 41. The support bottom block 42 serves to fix the main support rod 3, and it stably installs the main support rod 3 on the corresponding position of the injection molding machine through a firm connection, providing stable bottom support for the entire device. One end of the support inclined block 41 abuts against the center of the rotating shaft 2, which effectively supports and positions the rotating shaft 2 during rotation. The inclination angle and position of the support inclined block 41 are accurately calculated and designed to ensure that the rotating shaft 2 remains stable at different rotation angles, thereby ensuring the normal operation of the entire device.

[0032] Example 2: Reference Figures 1 to 4 An injection molding machine mold locking cylinder support rotating device mainly consists of a main support rod 3 and an outer support 4. The main support rod 3, as the core component of the entire device, undertakes the main task of supporting the mold locking cylinder 1. It is made of high-strength material and has good mechanical properties and durability, capable of bearing the huge pressure generated by the mold locking cylinder 1 during operation. The outer support 4 is ring-shaped and tightly surrounds the main support rod 3, forming a relatively stable external frame structure. This design not only enhances the stability of the entire device, but also provides reliable support for the installation and fixation of other components. There is a specific gap 23 between the outer support 4 and the main support rod 3, which is not simply a void, but has a key functional layout. Within the gap 23, a rotating shaft 2 is symmetrically arranged. This symmetrical layout ensures that the entire device maintains good balance during operation and avoids damage or production accidents caused by uneven stress.

[0033] One end of the rotating shaft 2 is a support column 21, which has good support performance and can flexibly rotate with the rotating shaft 2 in the slot 23. This flexibility provides convenience for the operation of the mold locking cylinder 1. During the injection molding process, the mold locking cylinder 1 needs to be adjusted according to the position and shape of the mold. The flexible rotation of the support column 21 can ensure that the mold locking cylinder 1 remains stable at different angles, thereby improving the quality of the product and the production efficiency. The other end of the rotating shaft 2 is a side positioning rod 22, which cooperates with the center positioning rod 32 at the top of the main support rod 3 to jointly fix the mold locking cylinder 1. Through the cooperation of the side positioning rod 22 and the center positioning rod 32, the mold locking cylinder 1 can be stably fixed on the device, avoiding product quality problems caused by cylinder shaking during the injection molding process. This fixing method is not only simple and reliable, but also can be adjusted according to the different sizes of the mold locking cylinder 1, with strong adaptability.

[0034] From the overall structure, the injection molding machine mold locking cylinder support rotating device adopts a mechanical structure support, which is one of the important features that distinguishes it from traditional devices. Mechanical structure support has the advantages of high stability and strong durability, and can maintain good performance in a long-term high-strength working environment. In actual production, the diameter of the mold locking cylinder 1 may vary due to different production needs, and the device can automatically adjust to effectively support mold locking cylinders 1 of different diameters. This automatic adjustment function is mainly due to the ingenious structure design of the rotating shaft 2 and the cooperation of the side positioning rod 22 and the center positioning rod 32, which allows the device to adjust itself according to the diameter of the mold locking cylinder 1, thereby ensuring the stability and accuracy of the cylinder in the support state. At the same time, the device also ensures that the mold locking cylinder 1 can rotate, which is of great significance to the production process of the injection molding machine. The side positioning rod 22 is a curved structure, which not only increases its own strength and stability, but also better adapts to the shape and position of the mold locking cylinder 1. A plurality of support bearings 5 are arranged side by side on the side positioning rod 22, which allows the side positioning rod 22 to more stably bear the pressure of the mold locking cylinder 1 during the fixing process, reduces friction, and prolongs the service life of the device. At the same time, these support bearings 5 can also automatically adjust their positions with the rotation of the mold locking cylinder 1, further ensuring the flexibility and stability of the cylinder rotation. This design not only improves the performance of the device, but also reduces maintenance costs, with high practical value.

[0035] The center positioning rod 32 is also provided with a plurality of support bearings 5. These support bearings 5 cooperate with the support bearings 5 on the side positioning rod 22 to provide all-around support and protection for the mold locking cylinder 1. When the mold locking cylinder 1 is fixed on the device, the support bearings 5 on the center positioning rod 32 can effectively disperse the pressure of the cylinder, avoiding deformation or damage of the cylinder due to excessive local pressure. At the same time, these support bearings 5 can also reduce the friction between the cylinder and the center positioning rod 32, ensuring the smoothness of the cylinder during rotation. This all-around support and protection design enables the mold locking cylinder 1 to maintain good condition during operation, thereby improving the production efficiency and product quality of the injection molding machine.

[0036] The outer support 4 includes a support bottom block 42 and a support inclined block 41. The support bottom block 42 serves to fix the main support rod 3, and it is firmly connected to the main support rod 3 to stably install it on the corresponding position of the injection molding machine, providing stable bottom support for the entire device. One end of the support inclined block 41 abuts against the center of the rotating shaft 2, which enables the rotating shaft 2 to be effectively supported and positioned during rotation. The inclination angle and position of the support inclined block 41 are accurately calculated and designed to ensure that the rotating shaft 2 remains stable at different rotation angles, thereby ensuring the normal operation of the entire device. This structural design not only improves the stability of the device, but also enhances its durability, enabling it to maintain good performance in a long-term high-strength working environment.

[0037] The main support rod 3 near the support bottom block 42 is provided with a first limiting block 31, which serves to abut against the support column 21, thereby preliminarily limiting the position of the rotating shaft 2. The port of the first limiting block 31 is designed as an arc surface, which can better fit the surface of the support column 21, reducing stress concentration between the two, and avoiding damage to the parts due to excessive contact stress. At the same time, the arc surface design also enables the support column 21 to rotate more smoothly, reducing frictional resistance and prolonging the service life of the device.

[0038] The main support rod 3 near the rotating shaft 2 is provided with a second limiting block 33, which cooperates with the support inclined block 41 to abut against the center of the rotating shaft 2. This design enables the rotating shaft 2 to be more stably supported during rotation. The side of the second limiting block 33 that contacts the center of the rotating shaft 2 is beveled, which can better disperse the pressure transmitted by the rotating shaft 2, avoiding deformation or damage of the parts due to excessive local pressure. At the same time, the beveled surface has a relatively large contact area with the rotating shaft 2, which can provide better support effect and ensure the stability of the rotating shaft 2 during rotation.

[0039] The diameter of the support column 21 is larger than the diameter of the rotating shaft 2, which can provide a larger supporting area when the support column 21 bears pressure, thereby better supporting the lock mode oil cylinder 1. The position where the support column 21 contacts the first limiting block 31 is an arc surface, which cooperates with the arc surface design of the first limiting block 31, can further reduce stress concentration, and ensure the smoothness and stability of the support column 21 during rotation.

[0040] The diameter of the rotating shaft 2 is larger than the diameter of the side positioning rod 22, which can provide a larger torque during rotation of the rotating shaft 2, thereby better driving the lock mode oil cylinder 1 to rotate. At the same time, the larger diameter of the rotating shaft 2 can also improve its own strength and rigidity, ensuring that it will not be deformed or damaged when bearing a larger pressure.

[0041] The utility model is not limited to the details of the above exemplary embodiments for those skilled in the art, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model.
