Abstract
Description
Technical Field
[0001] This utility model relates to the field of thick-bottom bottle manufacturing and processing technology, and in particular to a mechanism for preventing jamming during the up-and-down movement of the core injection in a thick-bottom bottle. Background Technology
[0002] Patent application number CN202222709952.3 describes a thick-bottomed bottle mold forming mechanism and an injection stretch blow molding mold. In order to make the bottom of the thick-bottomed bottle thick, the core is designed to move up and down. During injection, the core moves upward under the injection pressure, compressing the spring and making the bottom glue thicker. After the preform is demolded, the core returns to its original position under the action of the spring and repeats the next action.
[0003] In the above scheme, the core moves up and down in the core sleeve, and the glue position must be sealed to prevent the glue from overflowing. The fit cannot be too loose, so the core and the core sleeve are prone to wear and jamming and cannot move. To address this, a mechanism is designed to prevent jamming when the core moves up and down in a thick-bottomed bottle. Summary of the Invention
[0004] According to an embodiment of the present invention, a mechanism for preventing jamming during the up-and-down movement of a thick-bottomed bottle filling process is provided, comprising:
[0005] Injection sleeve;
[0006] Core injection, the core moves up and down inside the core injection sleeve;
[0007] The core injection fixing plate is fixedly sleeved on the top of the core injection.
[0008] The core injection sleeve fixing plate is fixedly sleeved on the core injection sleeve;
[0009] The core injection sleeve pad is fitted onto the core injection and is connected to the core injection sleeve fixing plate. The outer pad is located between the core injection fixing plate and the core injection sleeve fixing plate.
[0010] Also includes:
[0011] The wear-resistant insert is fixed inside the bottom end of the core sleeve and is fitted onto the core.
[0012] The positioning ring is set on the top of the core injection sleeve and between the core injection sleeve and the core injection sleeve.
[0013] Furthermore, the anti-wear insert is made of beryllium copper.
[0014] Furthermore, the positioning ring is made of bronze.
[0015] Furthermore, it also includes:
[0016] At least two positioning holes are provided on the wear-resistant insert;
[0017] At least two through holes are provided at the bottom of the core-filling sleeve. The number of through holes corresponds to the number of positioning holes, and their positions are one-to-one. Positioning pins are inserted into the corresponding through holes and positioning holes.
[0018] Furthermore, the axial center lines of the core-filling sleeve, core, wear-resistant insert, and positioning ring are all on the same straight line.
[0019] According to an embodiment of this utility model, a mechanism for preventing jamming during the vertical movement of a core injector in a thick-bottomed bottle comprises an anti-wear insert made of beryllium copper embedded at the bottom of the core injector sleeve and secured with a positioning pin. Beryllium copper has high hardness and good wear resistance, and because it differs from the core injector material, it is not easily worn. A bronze positioning ring is then embedded at the top of the core injector sleeve. This two-point positioning structure, consisting of the bottom beryllium copper insert and the top bronze positioning ring, effectively prevents the core injector from tilting, ensuring accurate vertical positioning, thereby avoiding wear and guaranteeing normal operation.
[0020] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.
[0025] First, combine Figs. 1-3 This invention describes a mechanism for preventing jamming during the up-and-down movement of the core injector in a thick-bottomed bottle, according to an embodiment of the present invention. It is used to prevent the core injector 200 from jamming during the up-and-down movement of the thick-bottomed bottle 900 during processing, and has a wide range of applications.
[0026] like Figs. 1-3As shown in the figure, an embodiment of the present invention provides a mechanism for preventing jamming during the vertical movement of a thick-bottomed bottle core injector. The mechanism comprises a core injector sleeve 100, a core injector 200, a core injector fixing plate 300, a core injector sleeve fixing plate 400, and a core injector sleeve pad 500. The core injector 200 moves vertically within the core injector sleeve 100; the core injector fixing plate 300 is fixedly sleeved on the top of the core injector 200; the core injector sleeve fixing plate 400 is fixedly sleeved on the core injector sleeve 100; the core injector sleeve pad 500 is sleeved on the core injector 200 and connected to the core injector sleeve fixing plate 400; an outer pad is located between the core injector fixing plate 300 and the core injector sleeve fixing plate 400.
[0027] like Figs. 1-3 As shown, the anti-jamming mechanism for the up-and-down movement of the core injector in a thick-bottomed bottle according to an embodiment of this utility model further includes: an anti-wear insert 600 and a positioning ring 700. The anti-wear insert 600 is fixed inside the bottom end of the core injector sleeve 100 and sleeved on the core injector 200. The anti-wear insert 600 is made of beryllium copper. The positioning ring 700 is disposed between the top of the core injector sleeve 100 and the core injector 200. The positioning ring 700 is made of bronze. An anti-wear insert 600 made of beryllium copper is embedded at the bottom of the core injector sleeve 100. Beryllium copper has high hardness and good wear resistance, and is different from the material of the core injector 200, so it is not easily worn. A positioning ring 700 made of bronze is embedded at the top of the core injector sleeve 100. Through the two-point positioning structure of the bottom beryllium copper anti-wear insert 600 and the top bronze positioning ring 700, the tilting of the core injector 200 is effectively prevented, ensuring accurate up-and-down positioning, thereby avoiding wear and ensuring normal operation.
[0028] Furthermore, such as Figs. 1-3 As shown, an embodiment of the present invention provides a mechanism for preventing jamming during the up-and-down movement of a thick-bottomed bottle core injection. This mechanism further includes at least two positioning holes 801 and at least two through holes 802. At least two positioning holes 801 are formed on the wear-resistant insert 600; at least two through holes 802 are formed on the bottom of the core injection sleeve 100. The number of through holes 802 and positioning holes 801 are opposite, and their positions are also opposite. Positioning pins (not shown in the figure) are inserted into the corresponding through holes 802 and positioning holes 801, thereby fixing the wear-resistant insert 600 to the core injection sleeve 100.
[0029] Furthermore, the axial center lines of the core injection sleeve 100, core injection 200, wear-resistant insert 600, and positioning ring 700 are on the same straight line.
[0030] Above, refer to Figs. 1-3This invention describes a mechanism to prevent jamming during the vertical movement of a core injector in a thick-bottomed bottle, according to an embodiment of the present invention. A beryllium copper wear-resistant insert 600 is embedded at the bottom of the core injector sleeve 100 and secured with a positioning pin. Beryllium copper has high hardness and good wear resistance, and because it is made of a different material than the core injector 200, it is less prone to wear. A bronze positioning ring 700 is then embedded at the top of the core injector sleeve 100. Through this two-point positioning structure of the bottom beryllium copper wear-resistant insert 600 and the top bronze positioning ring 700, the tilting of the core injector 200 is effectively prevented, ensuring accurate vertical positioning, thereby avoiding wear and guaranteeing normal operation.
