Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass bottle molds, and particularly relates to a limit structure for mold clamping of a glass bottle forming mold. Background Art
[0002] The forming of glass bottles requires the use of a primary mold and a forming mold. Generally, the male and female half molds of the existing forming mold and primary mold are positioned during mold clamping through the cooperation of vertical positioning ribs and positioning grooves. However, this positioning structure can only control the misalignment of the male and female molds in the horizontal direction. The installation errors or the dimensional errors of the male and female molds and their holding clamps (mounting brackets) may cause misalignment in the vertical direction, resulting in misalignment or too thick of the joint of the glass bottle, making it difficult to produce some bottles with high requirements for appearance and precision, such as high-end and mid-range cosmetic bottles, perfume bottles, wine bottles, etc. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, and provide a limit structure for mold clamping of a glass bottle forming mold that can perform effective upper and lower limits and is convenient for maintenance, which is suitable for producing glass bottles with high precision requirements.
[0004] The utility model is realized through the following technical solutions:
[0005] A limit structure for mold clamping of a glass bottle forming mold, which is used for the two half molds of a glass bottle, and includes a vertical positioning groove, a vertical positioning strip, a protruding member and a recessed member. The vertical positioning groove and the vertical positioning strip are respectively arranged on the mutually cooperating side surfaces of the two half molds and extend vertically along the two half molds. When the two half molds are clamped, horizontal positioning is carried out through the mutual cooperation of the vertical positioning groove and the vertical positioning strip. The protruding member and the recessed member are respectively arranged on the mutually cooperating side surfaces of the two half molds. When the two half molds are clamped, upper and lower limits are carried out by the protruding member being snapped into the recessed member.
[0006] Furthermore, the protruding member is a round nail component, and the recessed member is a round hole component. The round nail component includes an integrally arranged first fixing seat and a round nail. The round nail component is detachably installed on one of the mutually cooperating side surfaces of the two half molds through the first fixing seat, and the round nail protrudes from this side surface. The round hole component includes an integrally arranged second fixing seat and a round hole. The round hole component is detachably installed on the other opposite side surface of the two half molds through the second fixing seat, and the round hole is recessed from this side surface. The two half molds carry out upper and lower limits through the engagement between the round nail and the round hole.
[0007] Furthermore, mounting holes penetrating the half molds are arranged on both half molds. The first fixing seat and the second fixing seat are respectively detachably installed in the half molds through bolts passing through the mounting holes.
[0008] Further, the mutually cooperating sides of the two half - molds include vertically extending surfaces, and the round - nail component is installed on one of the vertically extending surfaces, while the round - hole component is installed on the other relatively vertically extending surface.
[0009] Further, there are two sets of the round - nail components and the round - hole components respectively. The two sets of round - nail components are respectively arranged on the vertically extending surfaces of the two half - molds, and the two sets of round - hole components are respectively arranged on the relatively vertically extending surfaces of the two half - molds.
[0010] Further, the protruding member is a trapezoidal protruding block, the recessed member is a trapezoidal groove, and the trapezoidal protruding block and the trapezoidal groove cooperate with each other to realize the up - and - down limit of the two half - molds.
[0011] Further, the mutually cooperating sides of the two half - molds include horizontally extending surfaces. The trapezoidal protruding block is installed on the horizontally extending surface, and the trapezoidal groove is installed on the other relatively horizontally extending surface.
[0012] Further, each half - mold includes a side mold and an upper mold. The upper mold is fixed on the side mold by bolts. The vertical positioning groove and the vertical positioning strip are respectively arranged on the side molds of the two half - molds, and the trapezoidal protruding block and the trapezoidal groove are respectively arranged on the upper molds of the two half - molds. When the two side molds are closed by the cooperation of the vertical positioning groove and the vertical positioning strip, the two upper molds are closed by the cooperation of the trapezoidal protruding block and the trapezoidal groove. At this time, the two half - molds realize horizontal limit and up - and - down limit simultaneously.
[0013] Further, there are two trapezoidal protruding blocks, and there are two opposite trapezoidal grooves.
[0014] Further, the trapezoidal protruding block and the trapezoidal groove are closely matched in the up - and - down direction to play the role of up - and - down limit.
[0015] The utility model realizes the up - and - down limit during mold closing by setting a protruding member and a recessed member on the glass - bottle forming mold, and realizes the horizontal limit during mold closing by setting a vertical positioning groove and a vertical positioning strip, thereby improving the precision and appearance of the glass bottle, enhancing the forming quality, and being beneficial to manufacturing high - grade glass bottles; setting the protruding member and the recessed member in the form of detachable round nails and round holes. When the round nails or round holes are deformed by high temperature, the round - nail components or the round - hole components can be directly disassembled and replaced, which is convenient for maintenance and does not occupy much installation space; setting the protruding member and the recessed member in the form of a trapezoidal protruding block and a trapezoidal groove, the limiting surface area is large, improving the reliability of the limit. Setting the trapezoidal protruding block and the trapezoidal groove on the up - and - down detachable half - molds is convenient for maintenance and replacement. The detachable half - molds also improve the use range and maintainability of the mold, expanding the use range. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0024] A limit structure for the mold closing of a glass bottle forming mold, which is used for the two half molds 1 of the glass bottle. It includes a vertical positioning groove 3, a vertical positioning strip 2, a protruding part and a recessed part. The vertical positioning groove 3 and the vertical positioning strip 2 are respectively arranged on the mutually cooperating side surfaces of the two half molds 1 and extend vertically along the two half molds 1. When the two half molds 1 are closed, horizontal positioning is carried out through the mutual cooperation of the vertical positioning groove 3 and the vertical positioning strip 2. The protruding part and the recessed part are respectively arranged on the mutually cooperating side surfaces of the two half molds 1. When the two half molds 1 are closed, up and down positioning is carried out by the protruding part being snapped into the recessed part. The horizontal positioning and up and down positioning of the two half molds 1 can improve the accuracy when the two half molds 1 are closed, and are suitable for the production of glass bottles with high requirements for accuracy and appearance.
[0025] Embodiment 1
[0026] Such as Figures 1 to 3As shown, the protruding part is the round nail component 4, and the recessed part is the round hole component 5. The round nail component 4 includes an integrally provided first fixing seat 42 and a round nail 41. The round nail component 4 is detachably mounted on one side surface where the two half-molds 1 cooperate with each other through the first fixing seat 42, and the round nail 41 protrudes from this side surface. The round hole component 5 includes an integrally provided second fixing seat 52 and a round hole 51. The round hole component 5 is detachably mounted on the other opposite side surface where the two half-molds 1 cooperate with each other through the second fixing seat 52, and the round hole 51 is recessed in this side surface. The two half-molds 1 are vertically limited by the engagement between the round nail 41 and the round hole 51. The forming temperature of the glass bottle is relatively high, and there is a risk of high-temperature deformation of the components on the mold. Since the mold needs to be repaired and maintained regularly, the detachable installation of the round nail component 4 and the round hole component 5 facilitates their disassembly and replacement without replacing the entire mold.
[0027] The detachable installation structure can adopt existing structures and methods. As one of the implementation manners, the bolt fixing method can be adopted. Specifically, mounting holes 8 penetrating through the half-mold 1 are provided on both of the two half-molds 1. The first fixing seat 42 and the second fixing seat 52 are respectively detachably mounted in the two half-molds 1 through bolts passing through the mounting holes 8. The ends of the bolts remain outside the half-mold 1, and the bolt columns pass through the mounting holes 8 and are screwed to the first fixing seat 42 or the second fixing seat 52. Bolt holes are reserved on the first fixing seat 42 and the second fixing seat 52, and the round nail component 4 and the round hole component 5 can be disassembled by screwing the bolts. If the bolt structure is difficult to screw due to high-temperature deformation, the bolt head can be cut off, and then the bolt column and the round nail component 4 or the round hole component 5 can be taken out of the mounting hole 8 together.
[0028] As one of the implementation manners, the side surfaces where the two half-molds 1 cooperate with each other include a vertically extending surface 13 and a horizontally extending surface 14. The round nail component 4 is mounted on one of the vertically extending surfaces 13, and the round hole component 5 is mounted on the other opposite vertically extending surface 13. The width of the vertically extending surface 13 is generally greater than that of the horizontally extending surface 14. Of course, it can also be arranged on the horizontally extending surface 14, depending on the specific shape of the half-mold 1. The vertical positioning groove 3 and the vertical positioning strip 2 are also arranged on the vertically extending surface 13.
[0029] In this embodiment, there are two groups of the round nail component 4 and the round hole component 5 respectively. The two groups of round nail components 4 are respectively arranged on the vertically extending surfaces of the two half-molds 1, and the two groups of round hole components 5 are respectively arranged on the opposite vertically extending surfaces of the two half-molds 1.
[0030] It should be noted that the round nail component 4 of the present invention also includes a pin structure. The round nail 41 protruding from the mating surface of the half-mold 1 can be a pin, and the corresponding round hole component 5 also includes a pin hole structure. The round hole 51 recessed in the mating surface of the half-mold 1 can be a pin hole.
[0031] Embodiment Two
[0032] As shown Figures 4 to 7 in the figure, the convex member is a trapezoidal convex block 6, the concave member is a trapezoidal groove 7, and the trapezoidal convex block 6 and the trapezoidal groove 7 cooperate with each other to realize the up-and-down limit of the two half-molds 1. The trapezoid facilitates the wedging of the convex block into the groove.
[0033] In this embodiment, the side surfaces of the two half-molds 1 that cooperate with each other include a vertically extending surface and a horizontally extending surface. The trapezoidal convex block 6 is installed on the horizontally extending surface, and the trapezoidal groove 7 is installed on the other horizontally extending surface opposite thereto.
[0034] As one implementation manner, each half-mold 1 includes a side mold 11 and an upper mold 12. The upper mold 12 is fixed on the side mold 11 by bolts. The vertical positioning groove 3 and the vertical positioning strip 2 are respectively arranged on the side molds 11 of the two half-molds 1, that is, the vertically extending surfaces of the half-molds 1. The trapezoidal convex block 6 and the trapezoidal groove 7 are respectively arranged on the upper molds 12 of the two half-molds 1, that is, the horizontally extending surfaces of the half-molds 1. When the two side molds 1 are closed by the cooperation of the vertical positioning groove 3 and the vertical positioning strip 2, the two upper molds 12 are closed by the cooperation of the trapezoidal convex block 6 and the trapezoidal groove 7. At this time, the two half-molds 1 simultaneously realize horizontal limit and up-and-down limit. Setting the half-molds 1 in a form that can be separated up and down is beneficial to the cleaning and maintenance of the mold, and is suitable for glass bottles with straight shoulders or wide shoulders. Setting the trapezoidal convex block 6 and the trapezoidal groove 7 on the upper mold 12, when the trapezoidal convex block 6 and the trapezoidal groove 7 are melted and deformed, the upper mold 12 can be directly replaced without replacing the entire half-mold 1.
[0035] In this embodiment, there are two trapezoidal convex blocks 6, and there are two opposite trapezoidal grooves 7. As shown Figure 6 in the figure, the trapezoidal convex block 6 and the trapezoidal groove 7 are closely matched in the up-and-down direction to play an up-and-down limiting role. As shown Figure 7 in the figure, the trapezoidal convex block 6 and the trapezoidal groove 7 can be in clearance fit in the horizontal direction.
[0036] The above detailed description is a specific description of the feasible embodiments of the present invention. This embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification without departing from the present invention shall be included in the patent scope of this case.
