Description

Technical Field

[0001] This utility model relates to the technical field of blow molding production equipment, specifically to a multi-station blow molding mold closing mechanism and a blow molding machine. Background Technology

[0002] A blow molding machine is a device that heats granular plastic to form a preform tube, and then blows the plastic into a mold cavity of a certain shape using the air force of the machine, thereby making a product.

[0003] The mold clamping mechanism, a crucial component of blow molding machines, is responsible for closing and maintaining close contact between the two mold plates to ensure uniform molding of the plastic within the mold cavity. Existing mold clamping mechanisms typically employ multiple drive sources and connection structures to drive the two mold plates. For example, multiple hydraulic cylinders or motors can be used to drive each mold plate separately to achieve the mold clamping action. Furthermore, a complex control system is required to coordinate the actions of multiple drive sources to ensure synchronous operation. This approach increases the overall size and structural complexity of the mold clamping mechanism, impacting debugging and production efficiency. The use of multiple drive sources also increases energy consumption and the failure rate, raising production and maintenance costs. Moreover, existing mold clamping mechanisms can only perform mold clamping processing on one set of mold plates at a time, failing to achieve simultaneous mold clamping processing on multiple sets of mold plates, further hindering production efficiency.

[0004] To ensure production efficiency, existing blow molding machines all use robotic arms to handle material and product loading and unloading. However, existing blow molding machines still have the following problems: When the robotic arms of existing blow molding machines transport preform materials to the mold closing mechanism, they need to first remove the product from the mold closing mechanism and then return to the loading point to clamp and transport the preform materials to the mold closing mechanism for blow molding. The transport continuity is poor, the transport time is long, and it affects production efficiency. Utility Model Content

7. A blow molding machine, characterized in that: The multi-station blow molding clamping mechanism includes any one of claims 1-6.

8. The blow molding machine according to claim 7, characterized in that: The blow molding machine includes a worktable, two chain drive mechanisms, a synchronous handling robot, and a blow molding mechanism. The multi-station blow molding and mold closing mechanism is set on the worktable. The two chain drive mechanisms are set at one end of the multi-station blow molding and mold closing mechanism, the synchronous handling robot is set at the other end of the multi-station blow molding and mold closing mechanism, and the blow molding mechanism is set below the multi-station blow molding and mold closing mechanism. Each chain drive mechanism is also equipped with a heat preservation and heating component. A first handling robot is also provided between the two chain drive mechanisms. A material handling mechanism is provided between the first handling robot and the chain drive mechanism. A linkage handling mechanism is provided between the synchronous handling robot and the material handling mechanism.

9. The blow molding machine according to claim 8, characterized in that: Each chain drive mechanism includes a chain bracket, a drive source, and a chain. The chain is disposed within the chain bracket and is connected to the drive source to form a drive connection. The chain is provided with multiple fixing modules. The material handling mechanism includes a fixed frame, two drive cylinders, and two interval separation components. The fixed frame is provided with multiple first guide rods. The drive cylinders are respectively mounted on the fixed frame and positioned below the first guide rods. The two sets of interval separation components are mounted on the multiple first guide rods and form a sliding connection. Each interval separation component includes multiple first sliders. A linkage module is provided between the first sliders, and one of the first sliders is provided with a mounting block. The mounting block is connected to the drive end of the drive cylinder. Each first slider is provided with a material fixing seat. The blow molding mechanism includes multiple sets of blow molding component groups, which are respectively arranged at the bottom of the multi-station blow molding and mold closing mechanism. The bottom of each blow molding component group is provided with an ejector pin assembly, which is used to lift and eject the preform. Each blow molding component group includes multiple blow molding components arranged in an array.

10. The blow molding machine according to claim 9, characterized in that: The first handling robot includes a linear module and two gripper modules. The linear module is equipped with a servo motor, and the gripper modules are mounted on the linear module in a sliding connection. Each of the two gripper modules includes a lifting assembly, a push-pull assembly, and a first gripper. The linkage conveying mechanism includes two first linear modules, each of which is equipped with a first servo motor and two first clamping modules. The first linear modules pass through the multi-station to form a blow molding and clamping mechanism. The two first clamping modules are both mounted on the first linear modules to form a sliding connection. There is a gap between the two first clamping modules. Each first clamping module is equipped with a first linkage component and a first clamp. The synchronous handling robot includes two second linear modules, each equipped with a second servo motor and a second clamping module; each clamping module includes a second pushing component and a second clamp.
