The specific embodiment
Specific embodiment 1:
Be that example describes with deep trouth class plastic parts below.
Fig. 1 to Fig. 4 constitutes specific embodiment of the utility model 1.
With reference to Fig. 1, present embodiment comprises dynamic model 1, cover half 2, core 3, TOP-TIP and cooling system; Form injection molding cavity between dynamic model 1, cover half 2, described TOP-TIP comprises runner 4, is arranged on hot mouth 5 and heater in the runner 4, is socketed with coolant jacket 51 on hot mouth 5, and the circumference of coolant jacket 51 is communicated with recirculated cooling water road 52.The circumference of coolant jacket 51 is provided with cannelure 53 and " O " shape seal groove 54 that is communicated with recirculated cooling water road 52.
In the present embodiment, described core 3 is provided with mold insert 31, and this mold insert 31 is positioned at the high position of corresponding plastic parts regenerator temperature.
With reference to Fig. 2 and Fig. 3, in the present embodiment, consider the coil that heating is arranged on the hot mouth 5 of hot flow path, although adopted air adiabatic to reduce hot mouth 5 external radiations heat energies on the hot flow path structural design, in fact the temperature of mould is still than higher around the hot mouth 5 of hot flow path, and in order to reach average cooling purpose, we have designed the cooling water channel loop structure at hot mouth 5 coolings of hot flow path, be socketed with coolant jacket 51 on the described hot mouth, the circumference of coolant jacket 51 is communicated with recirculated cooling water road 52; The circumference of coolant jacket 51 is provided with cannelure 53 and " O " shape seal groove 54 that is communicated with the recirculated cooling water road.The coolant jacket material adopts the SKD11 that hard material is wear-resisting and be difficult for getting rusty, circumference has cannelure and " O " shape seal groove for the cooling water circulation, can be with hot mouth 5 radiation, the heat of conduction is taken away, reduce near hot mouth 5 temperature of hot flow path thereby reach, for strengthening hot mouth 5 cooling effects of hot flow path, we generally adopt single group water route circulation 52.
With reference to Fig. 4, the characteristics of deep trouth class plastic parts are: product is block form, " product advances the glue point " G1, G2 is in the deep trouth bottom, and the private side muscle is very dark, in the mold cools down process, the heat of trench bottom is higher, do not improve cooling structure and be difficult to reach synchronous cooling purpose, therefore, near present embodiment position (trench bottom part) cast gate of corresponding plastic parts on the described core 3 is provided with the mold insert 31 that adopts the beryllium copper material to make.Structure is shown in figure four: show by practice, so both reached the synchronous cooling purpose of mould, shortened the cooling cycle again.
The utility model design principle: at first analyze according to " the flow analysis report of plastic parts ".The first step is confirmed the best gate location and the quantity of plastic parts, guarantees each cast gate flow equilibrium, and the filling time is the shortest.Second step was found near the high position of plastic parts regenerator temperature (cast gate as plastic parts as described in the present embodiment).Consider to strengthen cooling at these positions, adopt the good material of heat conduction---beryllium copper in case of necessity, do this position inlaid piece of mould, design the structure of " beryllium copper mold insert " dexterously, reduce the temperature of plastic parts regenerator temperature high-order bit, temperature is even when guaranteeing the plastic parts moulding, shortens cool time.The 3rd step was found the bad position of plastic parts exhaust, how to consider to reach the designing mould mold insert and to shorten the filling time.
In the present embodiment, cooling system adopts the structure identical with heater with the cooling system of conventional injection mold with heater.
Specific embodiment 2:
Present embodiment is that example describes with local dent than dark and geomery plastic parts less than normal:
With reference to Fig. 5, the characteristics of present embodiment are: depression is dark and geomery is little on the plastic parts, plastic cement is arranged on every side, the cooling water at these positions is difficult to directly reach, the part of redness just is difficult to cooling when goods cool off, in order to solve this difficult problem, present embodiment dark square hole place of corresponding plastic parts depression on described core 3 is provided with the mold insert 31 that adopts the beryllium copper material to make.Described mold insert 31 inside are provided with cooling water well construction 32 and partition 33.The heat of accumulation of heat eminence is taken away rapidly.The darker place cooling of these local dents is cooled off synchronously with entire product, thereby reaches the raising cooling effect, shortens the purpose of molding cycle.Other are identical with specific embodiment 1.
Specific embodiment 3:
Present embodiment is that example describes with the plastic parts with the high small sircle hole of dimensional accuracy and big hole:
With reference to Fig. 6, the characteristics of present embodiment are: shown in the high small sircle hole of product size precision, this class hole cooling water can't be arranged at all, the high heat of accumulation of heat just has only the material of pattern tool own to take away in the deep hole, cooling effect is bad, the present embodiment projection cylinder position that corresponding plastic parts precision is high on described core 3 is provided with the mold insert 31 (beryllium copper pin) that adopts the beryllium copper material to make, and described mold insert 31 inside are provided with cooling water well construction 32 and partition 33.Utilize the good thermal diffusivity of " beryllium copper " material to take away mold heat.Thereby make the very fast cooling of glue potential energy in the deep hole, guarantee the small sircle hole dimensional accuracy, thereby reach the synchronous cooling purpose of entire product, the final realization shortened cool time, improves the purpose of molding cycle.In the mould structure design, if the root of " beryllium copper pin " can strengthen, can design the cooling water radiating effect can be better.For high " beryllium copper pin " surface of required precision, we can select to electroplate hard Cr or coating Ti-C, increase surface abrasion resistance, guarantee the stability of die size.Other are identical with specific embodiment.
