Capsule mold

Abstract

A capsule mold relates to the technical field of molds and comprises an upper mold shell and a lower mold shell which are arranged from top to bottom, and a core mold is arranged between the upper mold shell and the lower mold shell; a multi-section type lifting structure used for prolonging the moving stroke of the core mold is arranged between the core mold and the lower mold shell. The utility model solves the problems in the prior art that the die cost is increased, the die weight is heavy, and the difficulty in mounting and dismounting is increased because the thickness of the lower die shell is generally required to be increased to reserve the stroke of the core die during the design in order to meet the requirement of the core die for enough ascending stroke so as to facilitate the release of the capsule positioned at the lower die shell part.

Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a capsule mold. Background Art

[0002] Rubber bladders are widely used in the tire vulcanization industry for tire inner cavity molding, while bladder molds are used for bladder shaping and vulcanization. At present, bladder molds are basically composed of three parts: upper mold shell, lower mold shell, and core mold. When the bladder needs to be demoulded after vulcanization, the core mold needs to rise enough to facilitate the bladder located in the lower mold shell to be ejected.

[0003] As the existing devices are used, their shortcomings are gradually exposed, mainly in the following aspects:

[0004] In order to meet the need for the core mold to have sufficient rising stroke to facilitate the removal of the capsule located in the lower mold shell, the thickness of the lower mold shell usually needs to be increased during design to leave room for the core mold stroke, which will increase the mold cost, increase the mold weight, and increase the difficulty of installation and disassembly.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the defects in the prior art, the utility model solves the problem that in the traditional technology, in order to satisfy the need for sufficient rising stroke of the core mold to facilitate the removal of the capsule located in the lower mold shell, the thickness of the lower mold shell usually needs to be increased during design to leave room for the core mold stroke, which will increase the mold cost, and the mold is heavy, making installation and disassembly more difficult.

[0007] In order to solve the above problems, the utility model provides the following technical solutions:

[0008] A capsule mold comprises an upper mold shell and a lower mold shell arranged from top to bottom, wherein a core mold is arranged between the upper mold shell and the lower mold shell;

[0009] A multi-stage lifting structure for extending the moving stroke of the core mold is provided between the core mold and the lower mold shell.

[0010] As an optimized solution, the multi-stage lifting structure includes a limit plate connected to the lower mold shell, and the limit plate is also arranged to be lifted vertically. An upper limit screw connected to the core mold is slidably provided on the limit plate, and a lower limit screw slidably connected to the lower mold shell is connected to the limit plate.

[0011] As an optimized solution, a coaxial slideway for constraining the upper limit screw is coaxially opened on the limit plate and the lower mold shell, and a coaxial slideway stepped hole abutting against the handle end of the upper limit screw is provided in the coaxial slideway of the limit plate.

[0012] As an optimized solution, a lower mold shell slideway for constraining the lower limit screw is provided on the lower mold shell, and a lower mold shell stepped hole abutting against the handle end of the lower limit screw is provided in the lower mold shell slideway.

[0013] As an optimized solution, the multi-stage lifting structure includes a limit plate connected to the lower mold shell, the lower end of the limit plate is fixedly connected to the limit column, the limit plate is also arranged to be lifted vertically, and the limit plate and the limit column slide together and are provided with a limit screw connected to the core mold.

[0014] As an optimized solution, the limit plate and the limit column are coaxially provided with a coaxial slideway for constraining the limit screw, and the coaxial slideway in the limit plate is provided with a coaxial slideway stepped hole that abuts against the handle end of the limit screw.

[0015] As an optimized solution, a lower mold shell sliding groove is opened on the lower mold shell, and the outer ring of the limiting column is fixedly connected to the limiting column boss slidably arranged along the lower mold shell sliding groove.

[0016] As an optimized solution, the multi-stage lifting structure includes a limiting column connected to the lower mold shell, and the limiting column is also arranged to be lifted vertically. A limiting screw connected to the core mold is slidably provided in the limiting column.

[0017] As an optimized solution, a lower mold shell slide groove is opened on the lower mold shell, the outer ring of the limit column is fixedly connected to a limit column boss slidably set along the lower mold shell slide groove, and the bottom of the lower mold shell is fixedly connected to a baffle that constrains the downward stroke of the limit column.

[0018] As an optimized solution, the limiting column is provided with a limiting column slideway for constraining the limiting screw, and the limiting column slideway is provided with a limiting column stepped hole abutting against the handle end of the limiting screw.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] Through the multi-stage lifting structure, under the condition of the same lower mold shell height, the core mold can obtain a longer stroke. When demolding, the core mold can be fully raised to make room for capsule demolding, making demolding more convenient.

[0021] Through the multi-stage lifting structure, the traditional design of increasing the thickness of the lower mold shell to obtain sufficient stroke is changed. Under the condition of the same stroke, the thickness of the lower mold shell does not need to be increased additionally, which effectively reduces the total weight of the mold, reduces costs and unnecessary waste, and is relatively easy and safe to install and disassemble.
