Description

Technical Field

[0001] The utility model relates to the technical field of synchronous mechanisms, and more specifically, to a synchronous mechanism for a large hollow blow molding machine. Background Technique

[0002] The mold clamping device generally mainly consists of front and rear fixed templates, a moving template, tie rods, a driving device for the moving template, etc. It is the main component of the mold clamping system of the blow molding machine. The mold clamping device of the blow molding machine is usually divided into three types according to its working principle: mechanical type, hydraulic type, and hydraulic-mechanical combined type.

[0003] At present, most in the industry adopt the method of mechanical limit fixation. By the collision of a template with a mechanical backstop, the limit positioning effect is achieved. The existing adjustment method has a large impact on the template, cannot ensure the synchronous operation of the template, and is easy to cause damage to the mold during the movement process. Therefore, in view of the above problems, a synchronous mechanism for a large hollow blow molding machine is specifically proposed. Content of the Utility Model

[0027] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a synchronization mechanism for a large hollow blow molding machine, including a frame 1, a first mold 2 and a second mold 3. On both opposite sides inside the frame 1, first sliding grooves 101 are provided. On the top of the frame 1, a third sliding groove 1010 is provided. At the bottoms of the first mold 2 and the second mold 3, a first L-shaped sliding rod 201 and a second L-shaped sliding rod 301 are respectively fixedly connected. On both opposite sides at the top inside the frame 1, sliding cylinders 102 are fixedly connected. Inside both of the two sliding cylinders 102, second sliding grooves 1012 are provided. The first L-shaped sliding rod 201 and the second L-shaped sliding rod 301 are both slidably connected in the third sliding groove 1010. One end of the first L-shaped sliding rod 201 and one end of the second L-shaped sliding rod 301 are both slidably connected inside the sliding cylinder 102. Inside the first sliding groove 101, a sliding block 1011 is slidably connected. Between the two sliding blocks 1011, a driving rod 103 is fixedly connected. On the surface of the driving rod 103, two sliding sleeves 104 are slidably connected. On the sides of both of the two sliding sleeves 104, a first movable connecting rod 105 is movably connected through a pin shaft 4. At the tops of the two first movable connecting rods 105, they are respectively movably connected to the sides of the first L-shaped sliding rod 201 and the second L-shaped sliding rod 301 through a pin shaft 4. At the top inside the sliding sleeve 104, two fixing plates 108 are fixedly connected.

[0028] By adopting the above technical solution, through the setting of the first movable connecting rod 105, the driving rod 103, the first L-shaped sliding rod 201 and the second L-shaped sliding rod 301, when the two molds move, the first L-shaped sliding rod 201 and the second L-shaped sliding rod 301 can slide inside the sliding cylinder 102, and then through the first movable connecting rod 105, it can drive the sliding sleeve 104 to slide on the surface of the driving rod 103. Through the linkage between the first movable connecting rod 105, the driving rod 103, the first L-shaped sliding rod 201 and the second L-shaped sliding rod 301, it can ensure that the two molds move smoothly, synchronously and reliably.

[0029] Refer to Figure 2 and Figure 3 , on the sides of both of the two sliding sleeves 104, a second movable connecting rod 106 is movably connected through a pin shaft 4.

[0030] The working principle of the present utility model is:

[0031] In use, people respectively install and connect the first L-shaped sliding rod 201 and the second L-shaped sliding rod 301 to the bottoms of the first mold 2 and the second mold 3. After the installation is completed, when the two molds are closed and opened, the first L-shaped sliding rod 201 and the second L-shaped sliding rod 301 can slide within the sliding cylinder 102. Then, through the first movable connecting rod 105, the sliding sleeve 104 can be driven to slide on the surface of the driving rod 103. By the movement of the sliding sleeve 104 on the surface of the driving rod 103, the movement of the two molds can be ensured to be stable, synchronous, and reliable. When the two molds are closed, the driving rod 103 is at the top end inside the frame 1. When the two molds are opened, the driving rod 103 is at the bottom end inside the frame 1.
