Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] The utility model provides a kind of storage type die head for blow molding machine, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5 It includes storage cylinder 1, storage core 2 slidingly installed in storage cylinder 1, die sleeve body 3 is arranged at the bottom of storage cylinder 1, die sleeve pressing ring 4 is fixedly installed at the bottom of storage cylinder 1 by bolt, lining ring 5 is arranged in storage cylinder 1, sliding sleeve 10 is screwed in storage core 2, mouth die 6 is fixedly installed on sliding sleeve 10, injection piston 7 is slidingly installed in storage cylinder 1, adjusting rod 8 is arranged in storage cylinder 1, guide sleeve 9 is fixedly installed in storage cylinder 1, air permeation hole 11 is opened in adjusting rod 8, storage cavity 12 is opened in storage cylinder 1.

[0025] Storage core 2 is slidingly installed on the side surface of adjusting rod 8, the bottom of lining ring 5 is fixedly connected with the top of die sleeve body 3 by bolt, and flow guide groove is formed between guide sleeve 9 and storage core 2.

[0026] The storage type die is used, first, the molten plastic is transported to the inside of the storage cavity 12 through the flow guide groove formed between the flow guide sleeve 9 and the storage core 2, the shot piston 7 is pushed up, the adjusting rod 8 moves up and down, the storage core 2 is synchronously moved up and down through the movement of the adjusting rod 8, the storage core 2 is contacted with the slope of the lining ring 5 through the movement of the storage core 2, thereby the lining ring 5 is pushed outwards, the die sleeve body 3 is synchronously moved through the movement of the lining ring 5, thereby the opening and closing of the die sleeve body 3 is realized, when the thickness of the discharged product needs to be changed, the sliding sleeve 10 is moved upwards or downwards, the mouth die 6 is synchronously moved through the movement of the sliding sleeve 10, the thickness of the extruded product is increased when the mouth die 6 is moved downwards, the thickness of the extruded product is reduced when the mouth die 6 is moved upwards.

[0027] Further, in order to facilitate the molten plastic to be added to the inside of the storage cavity 12, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , the side surface of the storage cylinder 1 is fixedly connected with the feeding port 13, the side surface of the storage core 2 is provided with the flow guide groove 14, the side surface of the storage cylinder 1 is provided with a plurality of overflow holes 22, the overflow holes 22 penetrate through the storage cylinder 1, and the overflow holes 22 are annularly arranged on the storage cylinder 1.

[0028] The storage type die is used, first, the plastic in the molten state is entered into the inside of the flow guide groove 14 carefully arranged on the storage core 2 through the feeding port 13, then the molten plastic flows into the flow guide groove between the flow guide sleeve 9 and the storage core 2 along the direction of the flow guide groove 14, along the flow guide groove, the molten plastic is smoothly entered into the inside space of the storage cavity 12, if the number of the molten plastic added in the process is too much, the excess plastic will flow out of the outside of the storage cylinder 1 along the plurality of overflow holes 22, thereby the operator can be timely informed that the current added plastic amount has exceeded the range that can be accommodated by the storage cavity 12, after the molten plastic is successfully added to the storage cavity 12, the operation of the shot piston 7 is followed, at this time, the shot piston 7 is pushed up, and the adjusting rod 8 connected with the shot piston 7 moves up and down, since the adjusting rod 8 and the storage core 2 have a linkage relationship, the up and down movement of the adjusting rod 8 drives the storage core 2 to synchronously move up and down, with the up and down movement of the storage core 2, it will gradually contact the slope of the lining ring 5, the contact will generate an outward force acting on the lining ring 5, since the lining ring 5 and the die sleeve body 3 are fixedly connected through bolts, the movement of the lining ring 5 will drive the die sleeve body 3 to synchronously move, in this way, the opening and closing action of the die sleeve body 3 is realized, finally, the molten plastic raw material is shot out of the die through the downward pressing operation of the shot piston 7, thereby the whole die working process is completed.

[0029] Wherein, in order to facilitate the control of the up-down axial movement of the adjusting rod 8, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the top of the storage cylinder 1 is provided with a servo cylinder 16, the top of the servo cylinder 16 is fixedly connected with a servo cylinder cover 15, and the bottom of the servo cylinder 16 is provided with a shot cylinder 18.

[0030] The top of the shot cylinder 18 is fixedly connected with a shot cylinder cover 17, the top of the shot cylinder cover 17 is fixedly connected with the bottom of the servo cylinder 16, and the bottom of the shot cylinder 18 is fixedly connected with a cooling plate 19.

[0031] The top of the storage cylinder 1 is fixedly connected with a support plate 21, the top of the support plate 21 is fixedly connected with a plurality of spacer columns 20, and the end of the spacer column 20 away from the support plate 21 is fixedly connected with the bottom of the cooling plate 19.

[0032] When the storage type die head is in use, the oil cylinder inside the servo cylinder 16 is started, at this time, the output end of the oil cylinder will push the shot piston 7 to slide towards the inside of the storage cavity 12 by means of the connecting action of the adjusting rod 8, with the movement of the shot piston 7, the space inside the storage cavity 12 is compressed, and the plastic in a molten state will be discharged from the bottom to the outside through the die head 6 and the die sleeve body 3, when the discharging process is completed, the output end of the oil cylinder which has been moved before will be retracted into the inside of the servo cylinder 16, during the blowing operation, if the temperature inside the die head is too high, the plastic raw material is extremely likely to be over-melted, such over-melting will bring a series of adverse effects, for example, the product may have various defects, such as uneven surface, insufficient structural strength and the like, and the production efficiency will also be reduced accordingly, in view of this, the cooling plate 19 is arranged in the design of the storage type die head to control the temperature, so as to avoid the occurrence of the above problems.

[0033] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
