Description

A kind of novel dual-color mold
Technical field
The present invention relates to technical field of mold, and in particular to a kind of novel dual-color mold.
Background technique
Most of accessory of automobile be tool there are two types of color plastic products, mostly by it is two-color injection-molded go out its needed for Shape.Double color injection, which refers to, is made different color by injection molding processes for two kinds of different colours or different types of plastics Or the process of the different finished product of appearance hardness, i.e., mavable module core is ejected after first time is molded, then mavable module core rotates 180 °, mavable module core is retracted into molding and carries out secondary injection molding.Currently, having no cooling inside the mavable module core of common double-color mold System, since injection moulding process temperature is higher, mavable module core is easy fever expansion, influences stripping result, causes final product quality irregular not Together;In addition, also increasing the coefficient of friction of mavable module core and mold, the service life of mold is reduced.
Further, since operation process, mandril drives mavable module core rotation, after long-time use, the contact surface of the two be easy by Damage, need to regularly replace mandril and mavable module core, and the cost of mandril and mavable module core is higher, virtually increases the production of enterprise Cost.
Summary of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of being provided with cooling fortune water-bound in a kind of mavable module core, And the novel dual-color mold of die life can be extended.
The technical scheme adopted by the invention is that: a kind of novel dual-color mold, including solid plate and moving template, the dynamic model Intralamellar part is respectively arranged with mavable module core, and the moving template is fixed on die holder, and the moving template is internally provided with for jacking up With the mandril of rotation moving template;The mavable module core is internally provided with the cooling fortune water-bound being connected to, the cooling with mandril Transporting water-bound includes the mandril water inlet pipe and mandril outlet pipe for being arranged in inside mandril and being symmetric, and is symmetricly set on The cooling water inlet pipe road of cooling water circulation loop inside mavable module core, the cooling water circulation loop and mandril and outlet pipe Road connection;The mandril is provided with the bearing holder (housing, cover) with self-lubricating function, the bearing in the one end contacted with moving template The inner wall of set and ejector pin contact is evenly equipped with oilhole, fills out inside the oilhole filled with the lubrication for being filled lubricating oil Material.
Further, the cooling water circulation loop includes that mavable module core water inlet pipe, mavable module core outlet pipe and mavable module core return Lu Guan, cooling water successively passes through mandril water inlet pipe, mavable module core water inlet pipe, mavable module core loop pipe, mavable module core outlet pipe, finally from top The outflow of bar outlet pipe.
Further, the lubrication filler is made of carbon material.
Further, the bearing holder (housing, cover) bottom outward radial stretches out the circumferential projection with moving template clamping.
Further, the solid plate is internally provided with the liquid storage chamber for storing hydrojet, and the liquid storage chamber is uniformly distributed There is hot flow path.
Further, the spray head that oriented injection die cavities spray injection molding liquid is connected below the liquid storage chamber, head of the nozzle is set It is equipped with the nozzle that diameter successively decreases from top to bottom, the injection die cavities of the nozzle alignment product.
Further, the solid plate bottom is provided with guide rod, and the moving template is provided with guide rod hole, the guide rod It is slidably fitted in the guide rod hole of moving template.
Compared with the prior art, the present invention has the following advantages:
1, double-color mold of the invention is internally provided with the cooling fortune water-bound being connected to mandril in its mavable module core, can make Mavable module core and mandril are quickly cooled down, and the processing temperature of stable prod stablizes final product quality;The friction system of the two can also be reduced Number, extends the service life of mold.
2, double-color mold of the invention is provided in the one end contacted with moving template with self-lubricating function in its mandril The inner wall of bearing holder (housing, cover), bearing holder (housing, cover) and ejector pin contact is evenly equipped with oilhole, is filled with inside the oilhole and is filled profit The lubrication filler of lubricating oil is increased the lubricant effect of the two with this, further extends the service life of mold.
