Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Referring to figs. 1 through Fig. 4, the utility model embodiment provides a kind of seamless rapid forming mold, comprises front mould 1 and rear mold 2 that mutual mould closes, the front of front mould 1 is provided with front die cavity 11, the front of rear mold 2 is provided with rear die cavity 21, and in the time that front mould 1 and rear mold 2 moulds close, front die cavity 11 and rear die cavity 21 are communicated with.
In front die cavity 11 on front mould 1, be provided with successively the first bottom 13 and the first core rod 14, in rear die cavity 21 in rear mold 2, be provided with successively the second bottom 23 and the second core rod 24, the first bottom 13 and the second bottom 23 are beryllium copper material, thermal conductivity is 245W/m DEG C, and the first core rod 14 and the second core rod 24 are steel material; In the time that front mould 1 and rear mold 2 moulds close, the first core rod 14 and the second core rod 24 form the die cavity of product, and die cavity is communicated with vacuum device, and this vacuum device is vacuum generator 3.
Utilize vacuum generator 3 to discharge by before penetrating to the gas in die cavity, allow and form vacuum in die cavity, like this in high speed ejaculation process, in die cavity, stop without air pressure, can greatly improve issuing velocity, strengthen plastic cement and fuse in die cavity, owing to being vacuum in die cavity, fast speed is also unlikely to product surface because tired gas burns again, improves product surface fineness.
Because the first bottom 13 and the second bottom 23 all adopt the beryllium copper material of high thermal conductivity, molding cycle is shortened more than 50% than the cycle of common die.
Be provided with ground floor water route 41 at the first core rod 14 and the second core rod 24 inside, ground floor water route 41 is communicated with hot water switch 51, and ground floor water route 41 is for passing into the hot water that maintains mold surface temperature; Be provided with second layer water route 42 at the first bottom 13 and the second bottom 23 inside, second layer water route 42 is communicated with cold water switch 52, and second layer water route 42 is for passing into the chilled water of rapidly heat being taken away.
Be different from prior art and adopt and on same water route, change hot water and chilled water, the present embodiment adopts the conversion that structurally realizes hot and cold water, and thermoconverter that need not be expensive is simple and practical.
The using method of this seamless rapid forming mold is as follows:
(1) mold closing, the first core rod 14 and the second core rod 24 form the die cavity of product, utilize vacuum generator 3 to discharge the air in die cavity, make it form vacuum, and then the plastic cement of melting is injected filling die cavity, and now vacuum generator 3 continues to bleed;
(2) treat that die cavity is full of plastic cement, after pressurize, hot water switch 51 is closed, cold water switch 52 is open, cold water is injected in second layer water route 42, and because the first bottom 13 and the second bottom 23 all adopt the beryllium copper material of high thermal conductivity, cold water passes unnecessary heat rapidly;
(3) cold water switch 52 is closed, die sinking, and in the process of die sinking, hot water switch 51 is open, and high-temperature-hot-water is injected in ground floor water route 41, and then mold closing enters next molding cycle.
By the water route design of multilayer diversification, utilize the heat of molten plastic itself to heat mould, keeping the surface temperature of mould, the time that greatly reduces the load of media and heat up again always.
As can be seen from the above description, the seamless rapid forming mold that adopts the utility model embodiment to provide, can reach following technique effect: one, molding cycle can be shortened more than 50% by the cycle of common die; Two, eliminate product surface and fuse line and surface fuses trace; Three, the mobile filling effect of reinforced plastics in die cavity, enhances productivity; Four, improve product surface fineness, make it to reach mirror effect; Five, solve and add the floating fine phenomenon that fine product produces; Six, quick-cooling and quick-warming controller equiment that need not be expensive.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
