Description
Technical field
The present invention relates to injection mold field, in particular to a kind of precise injection mould with cooling water channel.
Background technique
Injection mold is a kind of tool for producing plasthetics, and the plastic pellet after heating melting is injected by injection molding machine
To form required product in mould.
Currently, notification number is the Chinese utility model patent of CN207578964U, a kind of super more cave filling balances are disclosed
Injection mold, including upper mounted plate, A plate, B plate, support block, bottom plate, front cavity, rear cavity, locating ring and throttle into son,
The A plate is fixed at the bottom of upper mounted plate by locating ring, and the front cavity is arranged on the outer surface of A plate,
The B plate is fixed at the top of bottom plate by support block, and the rear cavity is arranged on the outer surface of B plate, more
A throttling enters son and is separately positioned in rear cavity.
In the injection mold in more caves or super more caves, generally require many thimbles, could it is stable by product from type chamber
Middle ejection, to need to offer more centre hole on mode, so that the mould of this super more cave filling balance injection molds
Benevolence is when opening up cooling water channel, since traditional water route is all to be arranged in a crisscross manner, so that traditional water route is difficult to avoid thimble
Hole, often this injection mold does not use cooling water channel cooling, but the heat-sinking capability of itself is relied on to radiate；This heat dissipation
Efficiency is slower, and since the long-time of mold is heated, mold is easily deformed.
Summary of the invention
The object of the present invention is to provide a kind of precise injection moulds with cooling water channel, its advantage is that cooling chamber and water storage
Chamber can pass through for more cooling water, rear mold water route water supply inlet and outlet, so that cooling water channel also can without being staggered
The more heat of mold is enough taken away, ensure that not with thimble or in the case where enter son and interfere, also can preferably be reduced
The temperature of mold.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of essence with cooling water channel
Close injection mold, including front cavity and rear cavity；The type chamber for shaped article, the rear cavity are offered in the front cavity
It is equipped with the type core plugged in type chamber, the type core is plugged in rear cavity in the form for entering son, and the front cavity is equipped with
For cooling down the preceding mould cooling component of front cavity, the rear cavity is equipped with rear mold cooling component；
The front cavity is equipped with into glue runner, and the rear cavity is equipped with the molding runners being connected into glue runner, it is described at
Type runner is connected to type chamber；
The rear mold cooling component includes the cooling chamber being provided in rear cavity and the rear mold water route being connected to the cooling chamber, institute
It states cooling chamber to be arranged by plesiotype core, the cooling chamber is connected to molding runners, is inserted in the cooling chamber for melting to be isolated
The spacing block of plastics and cooling water, the spacing block outside offer the water storage cavity being connected to cooling chamber.
