[0037] Due to the irregular structure of the blow molding product, the product will move with the movement of the blow molding die when the blow molding die is opened.

[0038] The above problems are effectively solved by the following embodiments.

[0039] As shown in Figure 3 , the automatic unloading system 3 in the present embodiment includes an automatic clamping mechanism 31 and an unloading driving mechanism 32. The unloading driving mechanism 32 can drive the automatic clamping mechanism 31 to move in X, Y and Z directions, so as to drive the automatic clamping mechanism 31 to the position of the blow molding die 6, and facilitate the clamping of the flash of the blow molding product 7 formed by the blow molding of the blow molding die 6.

In this embodiment, the two clamping plates 315 are symmetrically distributed, and the opening size of the clamping plate 315 can be adjusted according to the size of the extruded hollow blank.

[0041] In order to ensure that the two clamping plates 315 remain stable during the extension and contraction process, a plurality of symmetrical guide rods 316 are further arranged on the clamping plate 315, and correspondingly, guide grooves 317 matching the guide rods 316 are formed on the cylinder support plate 313, and the guide rods 316 can penetrate the guide grooves 317.

[0042] The blanking driving mechanism 32 in this embodiment can realize accurate grabbing of the blow molding product 7 by the automatic clamping mechanism 31, and can avoid interference with the work of the automatic oiling system 2. Figure 3 As shown in the figure, the blanking driving mechanism 32 comprises a blanking Y-axis moving module 322 connected with the automatic clamping mechanism 31, the blanking Y-axis moving module 322 is connected with a blanking X-axis moving module 321, the blanking X-axis moving module 321 is connected with a blanking Z-axis moving module 323, the blanking Z-axis moving module 323 is connected with the movable support 1 through a blanking Z-axis moving module support 324, the blanking Z-axis moving module 323 can drive the blanking X-axis moving module 321 to perform Z-direction lifting movement, the blanking X-axis moving module 321 can drive the blanking Y-axis moving module 322 to perform X-direction horizontal movement, and the blanking Y-axis moving module 322 can drive the automatic clamping mechanism 31 to perform Y-direction movement.

[0043] As the optimization of the automatic clamping mechanism 31, the clamping plate 315 is provided with an air cooling module 33, the air cooling module 33 comprises an air nozzle 331 with an air cavity, one end of the air nozzle 331 is provided with a connector 332 for connecting an external air source, and the other end is provided with a plurality of air holes 333 for discharging air; correspondingly, the clamping plate 315 is provided with an air nozzle groove 334 for embedding the air nozzle 331, and the end face of the air hole 333 does not exceed the clamping surface of the clamping plate 315; an electronic one-way valve is further arranged between the air nozzle 331 and the air source, the electronic one-way valve is connected with the central control system, and the time and amount of the ejected air can be controlled, and the air ejected can directly act on the flash of the blow molding product 7, which is beneficial to the rapid cooling and shaping of the flash.

In this embodiment, the liquid can be selected as a cooling liquid, which can not only rapidly cool the clamping plate 315, but also can secondary cool the clamped flash.

[0045] The working process of the automatic clamping mechanism in this embodiment is as follows:

[0046] When the blow molding mold is closed, the automatic clamping mechanism 31 is accurately positioned under the driving of the blanking driving mechanism 32, the air cooling module 33 and the liquid cooling module 34 are turned on, at the same time, the automatic clamping mechanism 31 pre-clamps the flash, the closed size of the pre-clamping can be adjusted according to the size of the mold parting surface, and the flash is finally clamped after cooling, so that the blow molding product can be prevented from being damaged due to the parting surface deviating from the center parting surface too much;

[0047] When the blow molding mold 6 is opened, due to the special-shaped structure of the blow molding product 7, it will move with the movement of one of the molds. In order to prevent the clamping mechanism from causing damage to the product, the automatic clamping mechanism 31 needs to be installed on the unpowered mold group (i.e. the unloading Y-axis moving mold group 322 in the embodiment). The unpowered mold group (the unloading Y-axis moving mold group 322) adopts a tension and compression spring group to balance the tension and compression force, and cooperates with guide rails, sliding blocks and other components to realize the free transfer of the automatic clamping mechanism along the opening and closing direction of the mold. The automatic clamping mechanism can be actuated under the action of a small traction force, and has the function of automatically returning to the original position, so as to ensure that the clamped blow molding product does not interfere with the blow molding mold.

[0048] When the ejection mechanism of the blow molding mold ejects the blow molding product, the automatic clamping mechanism together with the blow molding product returns to the original position under the action of the unpowered mold group (the unloading Y-axis moving mold group 322), and then performs the unloading action under the driving of the unloading X-axis moving mold group 321 and the unloading Z-axis moving mold group 323.

The roller shaft clamping plates 51 are supported and fixed by the support plates 53 which are connected perpendicularly to the movable support 1.

[0050] As shown in Figure 1 , the embodiment also provides a safety protection mechanism 9, that is, a fence area is arranged through a support. During the working process of the system, some components will move in the area, which will cause safety hazards to the operators. Therefore, the safety protection mechanism 9 is mainly used for preventing personnel from entering, and can identify and monitor the personnel who accidentally enter by installing an induction sensor. When the alarm is triggered, the central control system 4 can control the system to pause working.

[0051] The wiring of the central control system 4, the automatic oiling system 2 and the automatic unloading system 3 in the system can be arranged through the drag chain 10.

[0052] As shown in Figure 7As shown, the workflow of the system is as follows: the starting of a single production cycle is controlled by the central control system 4, the automatic oiling system 2 first starts the oiling action, then the extruder extrudes the hollow material, the sealing mechanism performs sealing, at the same time the blow molding mold is closed, the automatic clamping mechanism 31 of the automatic feeding system 3 moves to the upper end of the blow molding mold 6 as a whole through servo driving, and performs air cooling on the upper end flash to increase the strength of the flash, then the flash is clamped, when the blow molding mold 6 is opened, the automatic clamping mechanism 31 will move freely with the movement of the blow molded product, finally, the blow molded product is conveyed to the receiving table 8 through the flow channel mechanism 5 by the feeding driving mechanism 32 of the automatic feeding system 3 for subsequent operation.

[0053] The above merely illustrates the embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made by those skilled in the art within the spirit and principle of the present application shall be included in the protection scope of the present application.
