[0002] The mold clamping device is one of the important mechanisms of an extrusion blow molding hollow forming machine, which is used to load a mold and realize the opening and closing of the mold and the high-pressure mold clamping action. With the development of the technology of blow molding equipment, the functions of the extrusion blow molding hollow forming machine are increasingly rich and the automation level is significantly improved, which undoubtedly greatly improves the production efficiency and product quality.

[0003] However, with the replacement of equipment and the increasing requirements for automation, in order to meet the needs of equipment automation transformation, more functional components such as sensors, actuators, control systems, etc. have to be added inside the equipment, which directly leads to the increasingly compact internal space of the equipment.

Specific embodiments

[0021] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0022] A mold clamping device for facilitating mold replacement in this embodiment, referring to the attached Figure 1 and 2 , includes a sliding base 1, a mold clamping assembly 2 and a molding machine frame 3. The mold clamping assembly 2 is fixed on the sliding base 1, and the sliding base 1 is slidably connected to the molding machine frame 3, and the sliding base 1 can slide out or slide into the molding machine frame 3.

[0023] By providing a sliding base 1 slidably connected to the molding machine frame 3 and fixing the mold clamping assembly 2 on the sliding base 1, the operator can pull the sliding base 1 to cause a relative displacement between the sliding base 1 and the molding machine frame, so that the mold clamping assembly 2 together with the mold can be slid out of the molding machine frame 3 from the working position, so that the mold replacement operation can be carried out in a larger space. After the mold replacement operation is completed, the operator can also pull the sliding base 1 to make the sliding base 1 slide into the molding machine frame 3, so that the mold clamping assembly 2 returns to the working position. This avoids problems such as difficult operation caused by complex hoisting and positioning work inside the compact equipment, reduces the operation difficulty and safety risk, and also reduces the risk of equipment damage or personal injury that may be caused by improper operation.

[0024] Preferably, it further includes a pulley component 4. The pulley component 4 is arranged on the side of the sliding base 1 away from the molding machine frame 3, and the height of the pulley component 4 is adjustable. By providing the pulley component 4 connected to the sliding base 1 and the ground clearance of the sliding component being adjustable, it can ensure that the sliding component remains in contact with the ground or the plane under the sliding position of the sliding base 1, making the sliding base 1 move in or out of the molding machine frame 3 more smoothly, reducing the frictional resistance. Thereby, the force required for the operator to move the sliding base 1 can be reduced, thus reducing the working intensity and improving the working efficiency. It also ensures the stability and smoothness of the sliding base 1 during the movement process, reducing the safety risk caused by sudden movement or tilting.

[0025] Preferably, referring to the attached Figure 3 , the pulley component 4 includes an angle adjusting member 41 and a pulley body 42. The angle adjusting member 41 is hinged to one side of the sliding base 1, and the pulley body 42 is hinged to the angle adjusting member 41. The pulley body 42 is used to keep in contact with the ground or the plane under the sliding position of the sliding base 1, so as to reduce the frictional resistance. The angle adjusting member 41 is used to adjust the ground clearance height of the pulley body 42 to adapt to different working environments or the height of the feet of the molding machine frame 3.

[0026] Preferably, the pulley component 4 further includes a pulley bracket 43. The pulley bracket 43 is hinged to the bottom of the sliding base 1. The pulley bracket 43 is provided with a first connecting shaft 431 and a second connecting shaft 432. The pulley body 42 is rotatably connected to the first connecting shaft 431 through a bearing, and the pulley bracket 43 is hinged to the angle adjusting member 41 through the second connecting shaft 432. By providing the pulley bracket 43, the pulley body 42 is arranged on the side of the sliding base 1 away from the molding machine frame 3, and the pulley body 42 is hinged to the angle adjusting member 41 and the sliding base 1 through the pulley bracket 43, so that the ground clearance height of the pulley body 42 can be adjusted by adjusting the angle adjusting member 41.

[0027] Furthermore, the angle adjusting member 41 includes a swing shaft 411, a limit block 412, a threaded rod 413 and an adjusting nut 414. The swing shaft 411 is hinged to one side of the sliding base 1. The limit block 412 is arranged on the swing shaft 411. The threaded rod 413 passes through the limit block 412 and is hinged to the second connecting shaft 432. The adjusting nut 414 is in threaded cooperation with the threaded rod 413, and the end face of the adjusting nut 414 is in contact with the end face of the limit block 412. Thus, when adjusting the ground clearance height of the pulley body 42, by screwing the adjusting nut 414, the adjusting nut 414 and the threaded rod 413 are in threaded cooperation under the limitation of the limit block 412, so that the threaded rod 413 generates an up-and-down displacement. Due to the hinge connection between the limit block 412 and the sliding base 1, the hinge connection between the threaded rod 413 and the pulley bracket 43, and the hinge connection between the pulley bracket 43 and the sliding base 1, the up-and-down displacement of the threaded rod 413 drives the pulley bracket 43 to swing up and down, thereby realizing the adjustment of the ground clearance height of the pulley body 42. The structure is simple and the operation is convenient.

[0028] Preferably, a locking component is also included, and the locking component includes a pressing plate 11, a positioning platform 31 and a locking bolt (not shown in the attached drawings). The pressing plate 11 is arranged on one side of the sliding base 1, and the positioning platform 31 is fixed to the molding machine frame 3. The pressing plate 11 and the positioning platform 31 are both provided with front and rear connecting holes 111 opposite to each other, and the locking bolt is used to be threadedly connected with the connecting hole 111. By fitting the pressing plate 11 with the positioning platform 31, and connecting the locking bolt with the connecting holes 111 on the pressing plate 11 and the positioning platform 31 in turn, the sliding base 1 can be locked with the molding machine frame 3, thereby effectively preventing the sliding base 1 from accidentally moving due to misoperation or external force when the blow molding hollow molding machine is processing; and when the mold needs to be replaced, the sliding base 1 can be unlocked by quickly removing the locking bolt, which is simple to operate.

[0029] Preferably, it also includes a slide rail and a slider, the slide rail is arranged on the molding machine frame 3, the slider is arranged at the bottom of the sliding base 1, and the slider is slidably connected to the slide rail. Through the arrangement of the slide rail and the slider, the sliding cooperation between the sliding base 1 and the molding machine frame 3 is realized.

[0030] Preferably, an upper fixing frame 32 is provided on the molding machine frame, and the upper fixing frame 32 is provided above the mold clamping assembly 2, and the upper fixing frame 32 is used to support the blow molding device 5. By providing the upper fixing frame 32, the blow molding device 5 is fixed above the mold clamping assembly 2, so that when the sliding base 1 slides into the molding machine frame 3 and is in place, the mold clamping assembly 2 cooperates with the blow molding device 5, and when the sliding base 1 slides out of the molding machine frame 3, the mold clamping assembly 2 leaves the blow molding device 5, and at this time, there is no other equipment above the mold clamping assembly 2, so that the mold replacement operation can be performed in a larger space.

[0031] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way.
