Description

Technical Field

[0001] The present application relates to the technical field of die parts, and more specifically, to a cavity component disassembly structure and a preform mold. Background Art

[0002] A preform mold is generally composed of a core plate, a separating plate and a cavity plate. Among them, the core plate and the separating plate together serve as the moving template, and the cavity plate serves as the fixed template. The moving template is combined with the fixed template to form one or more mold cavities. In the mold cavity, the preform manufacturing melt is injected under high pressure through a runner. The preform manufacturing melt in the mold cavity forms a preform through cooling, and the preform can form a plastic bottle through subsequent blow molding treatment.

[0003] The mold cavity is generally defined by the space between a cavity component, a die head component and a core rod component. The cavity component is used to be arranged on the cavity plate and at least defines the body part of the outer shape of the preform; the die head component is used to be arranged on the separating plate and at least defines the neck part of the outer shape of the preform; the core rod component is used to be arranged on the core plate and at least defines the inner shape of the preform.

[0004] Among them, the cavity component usually includes a flange, a cavity and a bottom die that are precisely connected in sequence. The cavity is arranged in the cavity plate, the flange is arranged above the cavity plate, and the bottom die is arranged below the cavity plate. However, currently, when it is necessary to disassemble the flange or the cavity in a certain cavity component on the cavity plate, it is usually necessary to disassemble the entire cavity component separately and then knock it from the bottom die of the cavity component to disassemble the flange or the cavity of the cavity component. This operation process is too cumbersome, resulting in low disassembly efficiency of the flange or the cavity.

[0005] Therefore, the prior art still needs to be improved. Utility Model Content

The terms "first" and "second" are only used for the purpose of convenient description and cannot be construed as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0038] A preform mold is generally composed of a core plate, a separation plate and a cavity plate. Among them, the core plate and the separation plate together serve as a moving template, and the cavity plate serves as a fixed template. The moving template is combined with the fixed template to form one or more mold cavities. In the mold cavities, a preform manufacturing melt is injected under high pressure through a runner. The preform manufacturing melt in the mold cavities forms a preform through cooling, and the preform can form a plastic bottle through subsequent blow molding treatment.

[0039] The mold cavities are generally defined by the space between a cavity assembly, a mouth mold assembly and a core rod assembly. The cavity assembly is used to be disposed on the cavity plate and at least defines the body part of the outer shape of the preform; the mouth mold assembly is used to be disposed on the separation plate and at least defines the neck part of the outer shape of the preform; the core rod assembly is used to be disposed on the core plate and at least defines the inner shape of the preform.

[0040] Among them, the cavity assembly usually includes a flange, a cavity and a bottom mold that are precisely connected in sequence. The cavity is disposed in the cavity plate, the flange is disposed above the cavity plate, and the bottom mold is disposed below the cavity plate. However, currently, when it is necessary to disassemble the flange or the cavity in a certain cavity assembly on the cavity plate, usually the entire cavity assembly needs to be disassembled separately, and then the flange or the cavity of the cavity assembly can be disassembled by knocking from the bottom mold of the cavity assembly. This operation process is too cumbersome, resulting in low disassembly efficiency of the flange or the cavity.

[0041] For this reason, refer to Figure 1 and Figure 2, A disassembly structure for a cavity component provided in the first aspect of the embodiment of the present application. The disassembly structure for the cavity component includes a flange 1, and the flange 1 is used to be arranged above a cavity plate 7. A first disassembly groove 11 is formed on the edge of the end face of the flange 1 close to the cavity plate 7, and the first disassembly groove 11 is disassembled by a disassembly tool.

[0042] In this embodiment, by forming the first disassembly groove 11 on the edge of the end face of the flange 1 close to the cavity plate 7, when it is necessary to separately disassemble the flange 1, a disassembly tool can be used. The disassembly tool is aligned with the first disassembly groove 11, and the flange 1 can be directly disassembled from the cavity component on the cavity plate 7. The operation is simple, and the disassembly efficiency of the flange 1 is improved.

[0043] To improve the manufacturing efficiency of preforms, usually as many cavity components as possible are arranged on a cavity plate 7, and in order to utilize the space, the gap between the cavity components is set as small as possible. Optionally, refer to Figure 1 and Figure 2 , in an embodiment, at least two first disassembly grooves 11 are provided. The two first disassembly grooves 11 are respectively arranged on both sides of the flange 1. Compared with only providing one first disassembly groove 11, the two first disassembly grooves 11 provided in this embodiment can not only reduce the material cost of the flange 1, but also have more angles to operate (disassemble) the corresponding flange 1, and have more space for disassembly convenience.

[0044] Optionally, refer to Figure 2 , in an embodiment, the first disassembly groove 11 can be set as an inverted "L" - shaped groove. Correspondingly, the corresponding disassembly tool can be a flat disassembly screwdriver.

[0045] Optionally, refer to Figure 1 and Figure 3 , in an embodiment, the disassembly structure for the cavity component further includes a cavity 2. The cavity 2 has a first end 21 and a second end 22, and the first end 21 passes through the cavity plate 7 and is connected to the flange 1.

[0046] Optionally, refer to Figure 3 , in an embodiment, a second disassembly groove 23 can be formed on the circumferential side of the first end 21. In this embodiment, by forming the second disassembly groove 23 on the circumferential side of the first end 21 of the cavity 2 passing through the cavity plate 7, when it is necessary to disassemble the cavity 2, a disassembly tool can be used. The disassembly tool is aligned with the second disassembly groove 23, and the cavity 2 can be directly disassembled from the cavity component on the cavity plate 7. The operation is simple, and the disassembly efficiency of the cavity 2 is improved.

[0047] Further, refer to Figure 3, in one embodiment, the second disassembly groove 23 may be provided with at least two, and the two second disassembly grooves 23 are respectively arranged on both sides of the first end 21 and are located directly below the corresponding first disassembly groove 11. Compared with only setting one second disassembly groove 23, the two second disassembly grooves 23 provided in this embodiment can not only reduce the material cost of the cavity 2, but also have more angles to operate (disassemble) the corresponding cavity 2, having more space for disassembly convenience.

[0048] Optionally, referring to Figure 3 , in one embodiment, the second disassembly groove 23 is provided as a "U" - shaped groove, and the corresponding disassembly tool can be a flat disassembly screwdriver.

[0049] Optionally, in another embodiment, the first end 21 of the cavity 2 may also be provided with an annular disassembly groove (not shown in the figure) on its circumferential side. Among them, the disassembly principle of the annular disassembly groove is the same as that of the second disassembly groove 23, and the disassembly tools used for both are also common.

The bottom die 4 is configured to be disposed below the cavity plate 7 and connected to the second end 22 of the cavity 2. At least one fixed positioning groove 41 is provided on the bottom die 4. The second threaded fastener 5 has a head end and a tail end. The head end portion abuts against the fixed positioning groove 41 and the other portion is configured to abut against the cavity plate 7. The tail end is disposed on the cavity plate 7 to fix the bottom die 4 to the cavity plate 7. It can be foreseen that both ends of the cavity 2 are fixedly disposed within the cavity plate 7 through the flange 1 and the bottom die 4 respectively.

[0054] Optionally, referring to Figure 4 , Figure 5 and Figure 6 , in one embodiment, the cavity assembly disassembly structure further includes a socket seat 6. The socket seat 6 partially abuts against the fixed positioning groove 41 and the other portion is configured to abut against the cavity plate 7. The head end of the second threaded fastener 5 is disposed on the socket seat 6, and the tail end passes through the socket seat 6 and is disposed on the cavity plate 7.

[0055] Optionally, referring to Figure 6 , in one embodiment, two fixed positioning grooves 41 are provided on each bottom die 4. Correspondingly, two second threaded fasteners 5 are provided.

[0056] A preform mold provided in the second aspect of the embodiments of the present application includes the cavity assembly disassembly structure as described above.

The disassembly tool is aligned with the first disassembly groove 11, and the flange 1 can be directly disassembled from the cavity assembly in the cavity plate 7. The operation is simple, and the disassembly efficiency of the flange 1 is improved.
