Description

Technical Field

[0001] The utility model relates to the technical field of glass production and manufacturing, in particular to a die bottom plate structure of a glass mold. Background Art

[0002] A glass mold is a forming tool widely used in the production and manufacturing of glassware. After the high-temperature molten liquefied glass is introduced into the mold, it flows and fills the cavity inside the glass mold, and after cooling and solidifying, it forms a glassware corresponding to the shape of the glass mold. The quality and structural settings of the glass mold directly affect the forming quality and production efficiency of the glassware.

[0003] As shown in the attached Figure 1 In the prior art, as shown, the die bottom plate and the die bottom of the glass mold are arranged in one-to-one correspondence. The positioning posts arranged on the top of the die bottom plate pass through the corresponding positioning holes opened in the middle of the die bottom to relatively install and limit the die bottom plate and the die bottom; through vertical cooling holes penetrating through are also correspondingly and densely arranged circumferentially around the positioning posts on the die bottom plate and the die bottom to support the cooling of the glassware. However, in actual production, different glassware need to be formed using different glass molds. The one-to-one correspondence setting of the die bottom plate and the die bottom makes it necessary for the operator to remove and replace both the die bottom plate and the die bottom when changing production. Among them, the removal and replacement of the die bottom plate are time-consuming and laborious, which has a greater adverse impact on production efficiency. This drawback is particularly evident in mass production, and it also results in poor interchangeability of the glass molds and a large number of spare parts, which is not conducive to the control of production costs. At the same time, in the existing glass molds, in order to ensure the ventilation volume of the vertical cooling holes, the aperture of the blowing cooling holes is set relatively large, and it is easy for broken iron blocks and glass slag to fall into the cooling fan through the blowing cooling holes, affecting the service life of the cooling fan. In addition, during the process of changing the mold and producing the glassware, the positioning posts of the die bottom plate inevitably rub and collide with the die bottom, and the problem of positioning post fracture is likely to occur after long-term production, affecting the normal progress of production. Summary of the Utility Model

[0004] The utility model precisely aims to avoid the deficiencies existing in the above prior art, and provides a universal vertical cooling die bottom plate for a glass mold.

[0005] The utility model adopts the following technical solutions to solve the technical problems: A universal vertical cooling die bottom plate for a glass mold, the plate body of the die bottom plate is installed and fixed through threaded parts at each screw hole opened at its edge, and a positioning post is arranged in the middle of the plate body; the bottom mold of the glass mold is placed on the die bottom plate, and a positioning hole is opened thereon, and vertical cooling holes penetrating vertically are densely arranged in a regional manner. The positioning post is cooperatively clamped in the positioning hole to relatively install and limit the die bottom plate and the bottom mold;

[0006] It further includes a dust-proof mesh plate. A vertically penetrating vertical cooling groove is opened in the area of the plate body covering the vertical cooling holes. A dust-proof mesh plate with a mesh structure is cooperatively covered on the top of the vertical cooling groove. The aperture of the dust-proof mesh plate is smaller than that of the vertical cooling holes, and the setting density of the mesh holes of the dust-proof mesh plate is greater than the setting density of the vertical cooling holes.

[0007] Further, the vertical cooling grooves are arc-shaped grooves circumferentially and evenly arranged around the positioning column.

[0008] Further, a pair of the vertical cooling grooves are symmetrically opened on the plate body.

[0009] Further, a step structure is provided at the top of the vertical cooling groove, and the dust-proof mesh plate is cooperatively covered on the top of the vertical cooling groove through the step structure.

[0010] Further, the positioning column and the plate body are of a separable and detachable installation structure.

[0011] Further, mounting holes are opened on the plate body, and the positioning column is cooperatively inserted into the mounting holes.

[0012] Further, a limiting edge is formed along the radial outer edge at the bottom end of the positioning column, and the bottom of the mounting hole is correspondingly opened as a stepped round hole.

[0013] The utility model provides a general vertical cooling die bottom plate for a glass mold, which has the following beneficial effects:

[0014] 1. In the utility model, vertically penetrating vertical cooling grooves are opened on the die bottom plate of the glass mold in a way that can cover the largest ventilation area as much as possible, and a dust-proof mesh plate is covered on the top of the vertical cooling grooves, so that the ventilation area of the vertical cooling grooves can be communicated with the vertical cooling holes opened on different types of bottom dies. During the production change process, the operator only needs to replace the bottom die, effectively improving the production efficiency; the small aperture setting of the dust-proof mesh plate can effectively prevent broken iron blocks and glass slag from falling into the cooling fan, which is beneficial to extending the service life of the cooling fan.

[0015] 2. The die bottom plate of the utility model can be used in supporting with various types of bottom dies, effectively improving the interchangeability of the glass mold structure, simplifying the types and quantities of spare parts required to ensure production, and being beneficial to controlling the production cost.

[0016] 3. The positioning column and the plate body of the utility model are of a separable and detachable structure. The positioning column can be regularly replaced separately at a relatively low maintenance cost, avoiding production stagnation caused by the fracture of the positioning column, and at the same time reducing the overall maintenance cost of the die bottom plate.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] A general vertical cooling die bottom plate for a glass mold, as Figures 1 to 2 shown, its structural relationship is as follows: at each screw hole 13 opened at the edge of the plate body 11 of the die bottom plate 1, it is installed and fixed through threaded parts, and a positioning column 12 is provided in the middle of the plate body 11; the bottom die 3 of the glass mold is placed on the die bottom plate 1, on which a positioning hole 31 is opened, and vertically penetrating vertical cooling holes 32 are densely arranged in a regional manner. The positioning column 12 is cooperatively clamped in the positioning hole 31 to relatively install and limit the die bottom plate 1 and the bottom die 3;

[0023] It further includes a dust-proof net plate 2. A vertically penetrating vertical cooling groove 14 is opened in the area of the plate body 11 covering the vertical cooling holes 32. A dust-proof net plate 2 with a mesh structure is cooperatively covered on the top of the vertical cooling groove 14. The aperture of the dust-proof net plate 2 is smaller than the aperture of the vertical cooling holes 32, and the setting density of the mesh holes of the dust-proof net plate 2 is greater than the setting density of the vertical cooling holes 32.

[0024] In actual setting, the difference in aperture and density between the mesh holes of the dust-proof net holes 2 and the vertical cooling holes 32 should be large enough to ensure that when the dust-proof net plate 2 is used in cooperation with different types of bottom dies 3, the ventilation effect of the cooling air is basically not affected.

[0025] Preferably, the vertical cooling groove 14 is an arc-shaped groove evenly distributed circumferentially around the positioning column 12.

[0026] Preferably, a pair of vertical cooling grooves 14 are symmetrically opened on the plate body 11.

[0027] Preferably, a step structure 15 is provided at the top of the vertical cooling groove 14, and the dust-proof net plate 2 is cooperatively covered on the top of the vertical cooling groove 14 through the step structure 15.

[0028] In actual setting, the dust-proof net plate 2 is preferably arranged on the step structure 15 and fixedly welded to the die bottom plate 1.

[0029] Preferably, the positioning column 12 and the plate body 11 are of a separable and detachable installation structure.

[0030] Preferably, the plate body 11 is provided with mounting holes, and the positioning column 12 is inserted into the mounting holes in a matching manner.

[0031] In actual setting, the mounting holes and the positioning column 12 are preferably installed with interference fit.

[0032] Preferably, a limiting edge is formed along the outer edge of the bottom end of the positioning column 12 in the radial direction, and the bottom of the mounting hole is correspondingly provided as a stepped round hole.

[0033] When using the die bottom plate of the prior art to produce glassware and a product change is required, since the die bottom plate 1 and the bottom die 3 are arranged in a one-to-one correspondence, and the vertical cooling holes 32 on both are correspondingly opened, it is necessary to replace the die bottom plate 1 and the bottom die 3 simultaneously. The specific process is to disassemble one by one the threaded parts used to install and fix the die bottom plate 1. After removing the currently used die bottom plate 1 and the bottom film 3, take the die bottom plate 1 required for the product change, install and fix the die bottom plate 1 after the product change through each threaded part, and then install the bottom die 3 after the product change onto the die bottom plate 1. The operation is relatively complex, time-consuming and laborious.

[0034] When using the above-mentioned general vertical cooling die bottom plate to produce glassware and a product change is required, only the bottom die 3 needs to be replaced. The specific process is to remove the currently used bottom film 3 from the die bottom plate 1, take the bottom film 3 required for the product change, and install it onto the currently used die bottom plate 1. Since there is no need to disassemble and assemble the threaded parts, the operation of replacing the die during the product change is greatly simplified, and the die replacement efficiency is effectively improved.

[0035] The cooling structure of the above-mentioned general vertical cooling die bottom plate is a vertically penetrating vertical cooling groove 14 opened in the area covering the vertical cooling hole 32, and the vertical cooling groove 14 should be arranged to cover the largest ventilation area as much as possible. Therefore, even after the bottom film 3 is replaced and the arrangement of the vertical cooling holes 32 on the bottom film 3 changes, the vertical cooling groove 14 can still maintain complete communication with the vertical cooling holes 32, and will not affect the normal cooling of the glassware.

[0036] In addition, since the positioning column 12 is a fatigue structure in the die bottom plate 1, the fracture of the positioning column 12 is a common form of damage to the die bottom plate 1 in the prior art. When the positioning column 12 breaks during production, it is necessary to stop production urgently and arrange for the overall replacement of the die bottom plate 1 in a timely manner. This not only has a relatively high maintenance cost, but also affects the normal progress of production.

[0037] The positioning posts 12 of the above-mentioned general vertically cooled die bottom plate and the plate body 11 are arranged as a separable detachable structure. The cost of separately replacing the positioning posts 12 is relatively low. During production, the die bottom plate 1 can be properly maintained by periodically replacing the positioning posts 12 of the die bottom plate 1, and the normal progress of production can be ensured at a relatively low cost.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
