[0002] The preform mold is generally composed of a core plate, a separation plate and a cavity plate. The core plate and the separation plate serve as a movable mold plate, and the cavity plate serves as a fixed mold plate. The movable mold plate is combined with the fixed mold plate to form one or more mold cavities. The preform manufacturing melt is injected into the mold cavity through the runner under high pressure.

[0036] The preform mold is generally composed of a core plate, a separation plate and a cavity plate. The core plate and the separation plate serve as a movable mold plate, and the cavity plate serves as a fixed mold plate. The movable mold plate is combined with the fixed mold plate to form one or more mold cavities. The preform manufacturing melt is injected into the mold cavity through the runner under high pressure. The preform manufacturing melt in the mold cavity is cooled and formed into a preform.

[0037] After the preform is formed, it needs to be removed from the mold by a robot and placed on a conveyor belt for transport to the next workstation. However, existing robots typically use a preform removal cylinder (using suction) to remove the preform. Because the preform formed in the mold cavity is still warm, the cylinder can easily lose its grip on the preform or deform it.

[0038] For this purpose, see Figure 1 、 Figure 2 and Figure 3The first aspect of the embodiment of the present application provides a blank removal cooling cylinder, comprising a cylinder body 1, a blank removal core 2, a hollow screw 3 and a cooling water channel 4.

One end of the hollow screw 3 is arranged on the blank removal core 2, and the other end passes through the blank removal core 2 and is arranged on the cylinder body. 1, one end of the hollow screw 3 passing through the outside of the barrel body 1 is used to communicate with the air path in the blank removal plate, and is connected to the external air source through the air path in the blank removal plate, wherein the accommodating groove 11, the communication port and the hollow screw 3 are connected in sequence to form an air path. That is, the air path formed in this embodiment is connected to the external air source through the air path in the blank removal plate, so as to provide suction for the blank removal cooling barrel of this embodiment through the external air source. The cooling water path 4 is provided in the barrel body 1 and is located on the outside of the bottle blank, and is used to cool the bottle blank;

[0039] It can be foreseen that, in this embodiment, a connecting port is formed through the blank removal core 2, and an air path is formed by sequentially connecting the accommodating groove 11, the connecting port and the hollow screw 3. Since the air path is connected to the external air source, the blank removal cooling cylinder of this embodiment has the function of removing the formed bottle blank from the mold cavity. In addition, in this embodiment, a cooling water path 4 is provided so that the blank removal cooling cylinder of this embodiment can cool the bottle blank while removing the bottle blank, which can not only shorten the cooling cycle of the bottle blank, but also solve the problem of the bottle blank being deformed due to suction when the blank removal cooling cylinder removes the bottle blank.

[0041] Among them, the cooling water channel 4 can be opened on the inner side surface of the outer shell 14; the cooling water channel 4 can also be opened on the outer side surface of the inner seat 15; the cooling water channel 4 can also be set as two parts, one part of which is opened on the inner side surface of the outer shell 14 and the other part is opened on the outer side surface of the inner seat 15. When the outer shell 14 and the inner seat 15 are combined, the parts of the cooling water channel 4 opened on the inner side surface of the outer shell 14 and the outer side surface of the inner seat 15 are combined to form a complete cooling water channel 4.

[0042] Optional, see Figure 3In one embodiment, the cooling water channel 4 is configured to be opened on the outer surface of the inner seat 15 .

[0043] Optional, see Figure 3 In one embodiment, a water inlet hole 12 and a water outlet hole 13 are formed at one end of the inner seat 15 close to the hollow screw 3 , and the mounting groove and the accommodating groove 11 are formed in the middle of the inner seat 15 .

[0044] Optional, see Figure 4 In one embodiment, the cooling water channel 4 includes a first spiral cooling groove 41, a second spiral cooling groove 42 and a connecting groove 43 which are opened in the inner seat 15. The first spiral cooling groove 41 and the spiral cooling groove are opened in the inner seat 15 in a surrounding manner and are located on the outside of the mounting groove and the accommodating groove 11. The connecting groove 43 is opened in the inner seat 15 and is located on the outside of the accommodating groove 11 away from the mounting groove.

[0046] It is foreseeable that the cooling water channel 4 of this embodiment flows from the water inlet 12 into the first spiral cooling groove 41 , then flows through the connecting groove 43 into the second spiral cooling groove 42 , and finally flows out from the water outlet 13 .

[0047] Optional, see Figure 5 In another embodiment, the cooling water channel 4 includes a first spiral cooling groove 41, a second spiral cooling groove 42, a connecting groove 43, and a first linear cooling groove 44 and a second linear cooling groove (not shown in the figure) opened in the inner seat 15. The first spiral cooling groove 41 and the second spiral cooling groove 42 are opened in the inner seat 15 and are located on the outside of the accommodating groove 11. The connecting groove 43 is opened in the inner seat 15 and is located on the outside of the accommodating groove 11 away from the mounting groove. The first linear cooling groove 44 and the second linear cooling groove are opened in the inner seat 15 and are located on the outside of the mounting groove.

[0048] Among them, the water inlet hole 12 is connected to the first linear cooling groove 44, the first linear cooling groove 44 is connected to the first spiral cooling groove 41, the first spiral cooling groove 41 is connected to the connecting groove 43, the connecting groove 43 is connected to the second spiral cooling groove 42, the second spiral cooling groove 42 is connected to the second linear cooling groove, and the second linear cooling groove is connected to the water outlet hole 13.

Because the installation groove corresponds to the installation position of the blank core 2, rather than the accommodation position of the bottle blank, therefore, compared with setting a spiral cooling groove in the cooling water section corresponding to the outside of the installation groove (that is, the previous embodiment), this embodiment shortens the flow of the cooling water path 4 by setting two linear cooling grooves (the first linear cooling groove 44 and the second linear cooling groove) in the cooling water section corresponding to the outside of the installation groove.

[0050] Optional, see Figure 4 and Figure 5 In one embodiment, the connecting groove 43 is configured as an annular groove.
