Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0027] In the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0028] Referring to Figure 1 , 2 An embodiment of the present application provides a multi-station blow molding hollow forming equipment, which comprises:

[0029] The extrusion system 100 comprises three extruders 120 and a shared extruder head 110. The hollow forming equipment further comprises a high-altitude platform 510, and the extrusion system is installed on the high-altitude platform 510, so that the extruder head 110 is at a higher position, facilitating the subsequent robot to grab the blank below. A cutter is arranged below the extruder head 110. After the robot grabs the blank, the cutter cuts the continuous blank, and the robot grabs the upper part of the segmented blank and moves forward.

[0030] Referring to Figure 3 The four open-close mold forming mechanisms 200 are arranged in front of the extruder head 110. After the blank is fed into the open-close mold forming mechanism 200, the blank is blow molded and shaped in the open-close mold forming mechanism to form a hollow blow molded product. Since the blow molding process comprises actions such as mold closing, mold locking, and blow molding, the operation time is relatively long. In order to maximize the matching efficiency of blow molding and extrusion, four open-close mold forming mechanisms are used in the present application. After the robot feeds the blank into one open-close mold forming mechanism, the robot can return to the extruder head to grab the next blank during the mold closing waiting time.

[0031] The four open-close mold forming mechanisms 200 are symmetrically arranged in two rows and two columns on both sides of the central axis of the hollow forming equipment. This arrangement cooperates with the structure of the displacement mechanism to take and place the blank and the product in the shortest route and the most convenient displacement mechanism. Referring to Figure 4 , 5 .

[0032] The online flash removal mechanism 300 is arranged in front of the plurality of open-close mold forming mechanisms 200 and can remove excess waste from the blow molded product. The online flash removal mechanism 300 is connected to the product conveying line, and the blow molded product after flash removal enters the next station through the product conveying line.

[0033] The displacement mechanism 400 is arranged above the plurality of open-close mold forming mechanisms 200 and the online flash removal mechanism 300 and is used to grab the blank extruded by the extruder head 110 and feed the blank into each open-close mold forming mechanism 200, and is also used to take the blow molded product from each open-close mold forming mechanism 200 and feed the product into the online flash removal mechanism 300.

[0034] Referring to Figure 5 、 6 , the displacement mechanism 400 includes a pair of longitudinal rails 410 extending in the front-rear direction and parallel to the central axis of the hollow molding apparatus, a first cross rail 420 slidably disposed on the pair of longitudinal rails 410 and perpendicular to the central axis, a second cross rail 430, and a blank manipulator 440 slidably disposed on the first cross rail 420 and a product manipulator 450 slidably disposed on the second cross rail 430, the blank manipulator 440 and the product manipulator 450 each having a gripper 460 capable of moving up and down relative to the longitudinal rails and the cross rails.

[0035] The first cross rail 420 is close to the extruder head 110, and the blank manipulator 440 is used to send the blank into each open-close mold molding mechanism 200. The second cross rail 430 is close to the online trimming mechanism 300, and is used to grab the blow molded product and send it into the online trimming mechanism 300.

[0036] Since the online trimming mechanism 300 is located on the central axis of the hollow molding apparatus, the front part of the pair of longitudinal rails 410 can also be provided with a fixed third cross rail, and a manipulator is used to grab the hollow blow molded product after trimming and place it on the product conveying assembly line.

[0037] Further, the displacement mechanism 400 is located in front of the high-altitude platform 510, and the height of the gripper 460 does not exceed the high-altitude platform 510.

[0038] The hollow molding apparatus also has a hydraulic and electrical control cabinet 500, in order to make the overall structure of the apparatus compact and beautiful, the hydraulic and electrical control cabinet 500 is arranged below the high-altitude platform 510.

[0039] Please continue to refer to Figure 4 , the extrusion system 100, the open-close mold molding mechanism 200, the displacement mechanism 400, the online trimming mechanism 300 and the supporting hydraulic and electrical control cabinet 500 of the hollow molding apparatus of the present application are all installed in the blow molding rack. The extrusion system is located at the top of the rack and is responsible for extruding plastic pipe blanks O of appropriate length and weight. Four sets of open-close mold molding mechanisms 200 are installed in the rack, and molding molds (A\B\C\D) are installed respectively. The open-close mold molding mechanism opens and closes in a fixed position to meet the process requirements. The displacement mechanism can operate in a three-axis space. The online trimming mechanism P is responsible for trimming the blow molded product containing flash to form the final product. The online trimming mechanism is attached to an output device, which outputs the final product to the subsequent work station.

[0040] In the working process, the extrusion system extrudes plastic tube blank 0 with a proper length and weight, the blank mechanical arm 440 in the displacement mechanism moves the tube blank 0 through X, Y and Z three-axis space to put the tube blank 0 into any one open-close mold forming mechanism forming mold (A\B\C\D), and the blow molding is performed to form a plastic product with excess temperature and burrs. Then the product clamp in the displacement mechanism takes the product with burrs in the A\B\C\D mold cavity to the on-line burr removing mechanism P to remove the burrs to form the final product.

[0041] The conventional equipment moves a 3-ton open-close mold mechanism, and the plastic tube blank of 2Kg is moved in the application, so that the energy consumption of the equipment can be significantly reduced. Meanwhile, since four open-close mold forming mechanisms and three extruders are arranged, the production capacity of the hollow forming equipment can be greatly improved, the hollow product produced has low manufacturing cost and high processing efficiency.

[0042] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by the person skilled in the art that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the application, the utility model can have various changes and improvements, and the protection scope of the utility model is defined by the appended claims, the specification and the equivalent thereof.
