Description
Technical Field
The present invention relates to a key cooling and mold releasing method, and more particularly to a method for cooling and mold releasing a key by using the physical property of high thermal conductivity of a material with high thermal conductivity (thermal conductivity of the material: copper 401 Wm)-1K-1Aluminum 237Wm-1K-1) And double rapid local cooling of cooling water in key demoulding (the key production mould is usually made of iron and steel, and the thermal conductivity of the material is iron 80Wm-1K-160Wm of steel-1K-1) Therefore, the vacuum cooling demolding jig is cooled by the double rapid coolingThe key size is consistent with that of the forming male die, so that the key can be completely attached to the inner wall of the key product, and the targeted rapid cooling effect can be achieved and the key can reach the depth of the key product; and a demoulding edge strip for avoiding tearing and damage caused by insufficient film thickness during demoulding is additionally arranged at the corner excess material of the key product consisting of silicon rubber or rubber; and a vacuum suction pipeline is arranged on the vacuum cooling demoulding jig, so that the button product damage caused by uneven force application during demoulding can be avoided by adopting a comprehensive vacuum suction mode for demoulding, and the yield and the efficiency of the button product during demoulding can be effectively improved by using the button demoulding mode.
Background
Generally, when the silicone rubber or rubber of the key product made of silicone rubber or rubber is molded at high temperature, the physical properties of the material are swelling and soft; because the key product expands to enlarge the size of the key product, and further the expansion force between the key product and the molding master die expands to increase the adhesion and the friction between the key product and the molding master die, the demoulding difficulty and the demoulding reject ratio of the key product are increased; in addition, the physical properties of the material are soft and inelastic during high-temperature curing, and the key product is damaged by pulling during demolding, which causes the yield and efficiency of demolding the key product at high temperature to be low.
Generally, when demoulding a key product, manual demoulding and high-pressure air gun cooling are adopted, and when the key product is demoulded manually, uneven force application and insufficient bearing force and scalding of hands of personnel due to direct facing to the high temperature of a production mould are caused; when the high-pressure air gun is used, the air gun can only be cooled in a single point and a certain range, so that the key product in a small or deep position is not easy to cool, the key product which is most required to be cooled and is deeply sunk in the production master die cannot be effectively cooled, the production master die is continuously blown by high-pressure air to be cooled, and the production master die is not easy to demould and leaves the heating time for too long to generate temperature drop, so that the production master die needs to be heated by the die for one time before the next key product is produced due to uneven temperature and insufficient temperature of the die, otherwise, the key product produced secondarily is not cured in some places due to uneven temperature distribution and insufficient temperature of the die, the leveling of the key product composition material and other production defects are generated, and the production period is prolonged; especially when the distance between the keys of the key product is not enough and the height of the keys is too high, the demoulding difficulty of the key product is increased; and because the high pressure of the high pressure air gun is concentrated on one point, the high pressure air gun still stays at high temperature and the constituent materials are not cooled to complete bonding with the material properties of the constituent materials such as: in the case of high ductility and high elasticity, the key product may be damaged by the high pressure blow from the high pressure air gun.
The corner material of the key product is often placed only for ensuring the finish degree of the key product and the convenience of demoulding, and the composition material will diffuse and flow around at high temperature, which also causes the problem of insufficient film thickness at the corner material, and the insufficient film thickness will also cause the physical properties of the high-ductility and high-elasticity material of the composition material to be reduced, so that the corner material will be damaged from the corner material due to uneven force application during manual demoulding, and the key product will be damaged.
Disclosure of Invention
The invention aims to provide a key cooling demoulding way, which comprises a key product consisting of silicon rubber or rubber, and a demoulding edge strip which is formed at the corner excess material of the key product together, so as to avoid the damage of the key product caused by the tearing due to the insufficient film thickness at the corner excess material during demoulding, and the key product can be removed together with the removal of the corner excess material in the future without adding extra processing and removing procedures; and at least one vacuum cooling demolding jig which is made of a material with high heat conductivity coefficient and has the same size with the key on the molding male mold, the vacuum cooling demolding jig can completely and completely adhere to the inner wall of the key product so as to completely and deeply conduct heat conduction and temperature reduction aiming at the needed key product, and a vacuum suction pipeline and a cooling water inlet pipeline are arranged in the jig; the key product is quickly and pertinently cooled by the high heat conductivity characteristic of the high heat conductivity coefficient material and the double cooling of cooling inlet water, the key product is expanded and softened due to the material generated in the high-temperature forming process, and the damage of the key product caused by uneven force application in the demoulding process can be reduced by fully sucking air in vacuum to demould.
The vacuum cooling demolding jig is composed of copper or aluminum with high thermal conductivity coefficient and alloy thereof (thermal conductivity: copper 401 Wm)-1K-1Aluminum 237Wm-1K-1) Generally, the key production mold is made of iron or steel (thermal conductivity: iron 80Wm-1K-160Wm of steel-1K-1) The key product which needs to be rapidly cooled is subjected to heat conduction and cooling by virtue of the physical characteristics of high heat conduction of the high-heat-conductivity material (the heat conduction speed of copper and aluminum can be 3-8 times faster than that of iron and steel); even if a material with high heat conductivity coefficient is used, the heat conduction and heat dissipation efficiency of the high heat conduction material can be ensured only by the environment with temperature difference and heat dissipation at two ends, so that a cooling water inlet pipeline is arranged in the vacuum cooling demolding jig, the temperature rise of the vacuum cooling demolding jig caused by a continuous cooling program can be effectively reduced, the heat conduction and heat dissipation efficiency of the vacuum cooling demolding jig is reduced, cooling water with different temperatures can be provided according to the required cooling efficiency, and the cooling water inlet pipeline not only can cool the vacuum cooling demolding jig, but also can provide a cold source for cooling key products; the vacuum cooling demolding jig can be composed of more than one component made of materials with high thermal conductivity according to the difficulty degree of the vacuum cooling demolding jig in the processing and installation procedures, and only the required vacuum air suction pipeline and the cooling water inlet pipeline are respectively processed on the materials with high thermal conductivity, and then the components of the materials with high thermal conductivity which are respectively processed are combined into the vacuum cooling demolding jig.
In order to achieve the purpose, the key cooling demolding mode provided by the invention can be comprehensively attached to the inner wall of a key product to provide targeted, rapid and effective heat conduction and temperature reduction, can also ensure that the material physical properties of the key product can be bonded to complete the material physical properties with high ductility and high elasticity due to rapid temperature reduction, and the demolding edgings can double improve the demolding yield and the production efficiency, and can also ensure that an operator does not need to directly contact a high-temperature production mold and a key product during the operation and demolding due to the vacuum cooling demolding jig, thereby effectively ensuring the safety of the operator and the production efficiency; therefore, even when the distance between the key units of the key product is insufficient and the key units are too high, the demoulding is difficult, the demoulding yield and the demoulding efficiency can be effectively improved; the vacuum cooling demoulding jig is composed of at least one component according to the difficulty of the processing and installation procedures of a vacuum suction pipeline and a cooling water inlet pipeline to be arranged, and the vacuum cooling demoulding jig is composed of at least one component made of high-thermal-conductivity materials, so that the functions of vacuum suction and cooling water inlet cannot be influenced, and the processing and assembly procedures of the vacuum cooling demoulding jig are simpler and more convenient.
