[0001] This utility model relates to the technical field of extrusion dies for PE protective film production, and in particular to an extrusion die for PE protective film production. Background Technology

[0002] A PE protective film blown film die is a die head specifically designed for blown film machines used in the production of PE protective films. It uses a blow molding process to extrude molten plastic into a tubular film, which is then cooled, stretched, and wound up to ultimately produce the PE protective film.

[0003] Existing blown film dies for PE protective films mainly consist of a die body, die head, die core, and flow divider cone. These four parts are assembled together during use, and the connections between them are all accomplished by multiple bolts. However, bolted connections are not convenient for both installation and disassembly, and frequent use of bolts will cause wear on the mating thread grooves. Therefore, the connection method of the components in existing blown film dies for PE protective films is inconvenient. To address this, we provide an extrusion die head for PE protective film production. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: an extrusion die for producing PE protective film, comprising: a blow molding mechanism 1, the blow molding mechanism 1 including a mold body 11, a die 12 provided at the top of the mold body 11, a die core 13 sleeved inside the mold body 11 and the die 12, a flow divider cone 14 sleeved inside the mold body 11, and connecting mechanisms 2 provided on both sides of the mold body 11. Each connecting mechanism 2 includes a vertical rod 21, one end of which is provided with a mounting block 22, which is sleeved inside the die core 13; the other end of which is provided with a mounting block 23, which is sleeved inside the flow divider cone 14; and locking blocks 24 are sleeved inside both mounting blocks 22 and 23, and the locking blocks 24 are slidably connected to both mounting blocks 22 and 23. The locking block 24 is fixedly connected to the upright 21. The die 12 has a fitting block 25 inside. Both sides of the mold body 11 are provided with fixing mechanisms 3. The fixing mechanism 3 includes a connecting block 31. The connecting block 31 has a bidirectional threaded rod 32 inside. The outer surface of the bidirectional threaded rod 32 has a threaded block 33. One end of the threaded block 33 is fixedly connected to a locking post 34. Mounting block 1 22 is slidably connected to the mold core 13. Mounting block 23 is slidably connected to the flow divider cone 14. The fitting block 25 is slidably connected to the die 12. The fitting block 25 is fixedly connected to the upright 21. One side of the upright 21 is provided with a fixing block 26. The fixing block 26 is fixedly connected to the upright 21. The mold core 13 is slidably connected to the mold body 11 and the die 12. The flow divider cone 14 is slidably connected to the mold body 11.

[0020] In this embodiment, a support rod 21 is provided, which connects mounting block 1 22 and mounting block 23. Mounting blocks 1 22 and 23 are provided, and mounting grooves that fit into mounting blocks 1 22 and 23 are respectively provided on the mold core 13 and the diverter cone 14. Therefore, mounting blocks 1 22 and 23 cannot move laterally after installation. A locking block 24 is provided, which can fit inside mounting blocks 1 22 and 23. With the cooperation of the support rod 21, mounting blocks 1 22 and 23 cannot move longitudinally. The movement of the mold core 13 and the diverter cone 14 allows them to remain stable under the action of mounting block 1 22 and mounting block 23. At the same time, a fitting block 25 is provided, and the fitting block 25 is fixedly connected to the upright 21. The fitting block 25 can be sleeved inside the die 12. Therefore, under the action of the connecting mechanism 2, the mold body 11, the die 12, the mold core 13 and the diverter cone 14 can be connected into a whole. A fixing block 26 is provided, and a locking hole is provided on the fixing block 26 to fit into the locking post 34. Therefore, the locking post 34 can be locked into the interior of the fixing block 26, so that the entire connecting mechanism 2 can remain stable.

[0021] Example 2 like Figures 1-4 As shown, the connecting block 31 is fixedly connected to the mold body 11, the threaded block 33 is threadedly connected to the bidirectional threaded rod 32, the threaded block 33 is sleeved inside the connecting block 31, and the threaded block 33 is slidably connected to the connecting block 31. One end of the bidirectional threaded rod 32 is provided with a hexagonal block 35, which is fixedly connected to the bidirectional threaded rod 32. One end of the bidirectional threaded rod 32 is sleeved with a bearing 36, which is placed inside the connecting block 31. The bearing 36 is fixedly connected to the inner wall of the connecting block 31 and the outer surface of the bidirectional threaded rod 32.

[0022] In this embodiment, a fixing mechanism 3 is provided, which can be used in conjunction with the connecting mechanism 2 to ensure the stability of the blow molding mechanism 1. A bidirectional threaded rod 32 is provided, which can drive the two threaded blocks 33 to move simultaneously in opposite directions. As a result, the locking pin 34 can enter the interior of the fixing block 26 under the drive of the threaded blocks 33, thereby achieving the purpose of fixing the fixing block 26.

[0023] Working principle: like Figures 1-4As shown, in use, the present invention can first be fitted onto the outer surface of the diversion cone 14, then the die 12 can be placed on one side of the mold body 11, and then the die core 13 can be fitted onto the inside of the mold body 11 and the die 12. At this time, the first mounting block 22 is installed in the mounting groove opened on the die core 13, and the die core 13 is kept stable. Then, the second mounting block 23 is placed in the mounting groove opened on the diversion cone 14, and the second mounting block 23 is kept stable. Then, the upright rod 21 drives the locking block 24 to approach the first mounting block 22 and the second mounting block 23, so that the locking block 24 can engage with the inside of the first mounting block 22 and the second mounting block 23. Simultaneously, the engaging block 25 can enter the interior of the die 12, while the fixing block 26 can be positioned appropriately. Then, an auxiliary tool is used to fit onto the outer surface of the hexagonal block 35 and rotate the hexagonal block 35. The hexagonal block 35 can then rotate the bidirectional threaded rod 32. With the cooperation of the bearing 36, the bidirectional threaded rod 32 can drive the two threaded blocks 33 to move simultaneously towards or away from each other until the two locking pins 34 can simultaneously engage with the interior of the fixing block 26. Thus, the entire connecting mechanism 2 and the blow molding mechanism 1 can maintain a stable state and can be easily disassembled.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
