Description
Technical field
The present invention relates to the cooling systems of plastic ＆ rubber blade technical field of mold, especially a kind of to be set with profile-followed water route
The cooling system of meter.
Background technology
Plastic ＆ rubber blade in the fields extensive use such as 3C electronic products, white domestic appliances, automobile, simultaneously because technological innovation and
The continuous promotion of product quality, continuous pursuit of the above field to high-quality impeller, also determines plastic ＆ rubber blade in product size
It increases in terms of the functional attributes such as precision and dynamic balancing parameter, this also meets the manufacture of plastic ＆ rubber blade with molding technique
Carry out new challenge.It is well known that in plastic injection molding, the adjusting of the temperature of mold is all by temperature such as external die heaters
Control device controls corresponding medium and is flowed into die waterway pipeline by pipeline, leads to heat transfer to realize to mold
Temperature is regulated and controled, and whether the heat transmission in this link is balanced, directly affects the contraction distortion amount after formed product, to shadow
It rings and arrives product quality.Traditional plastic ＆ rubber blade class mold belongs to round mould core structure, but because plastic ＆ rubber blade product reinforcing rib position compared with
More, generally using the machining modes such as milling are bored, can not detour processing, can only laterally or longitudinally add along straight line for the processing in traditional water route
Work, and water route with the equidistant design of product, can not in this way result in water route distance product distance have it is close have remote, flow is for a long time
After cycle, temperature is then unbalanced everywhere on mode, and non-uniform Temperature Distribution causes product cooling heterogeneous, final result to lead
Cause deformation of products.
And in practical application, the final quality of impeller class product is directly determined by 2 important parameters, one be product circle
Appearance profile (end face run-out, circular runout), it determines whether the volume of product is evenly distributed in all angles.Second is that
The rotation imbalance amount of product, it determines whether the quality of product is evenly distributed in all angles.At present using tradition
The product of the impeller mold production of water route scheme, appearance profile (end face run-out, circular runout) are controlled substantially in 0.8mm or so,
After portioned product tolerance exceeds, it has to take the modes such as post-processing to be corrected, production cost further increases；And in plastic cement
Impeller product rotation imbalance value control aspect, the value of conventional impellers product rotation imbalance amount generally in 12mg.mm or so, and
Drawing requirement ideal value then in 4mg.mm hereinafter, encountered in production rotation imbalance value it is exceeded when, generally use dynamic balancing
After machine measures, and correction is balanced by the way of increasing clump weight, portioned product generally requires to check simultaneously compensation correction
2-3 times, such to measure the production model corrected, production cost is relatively surprising.
Still further aspect will mould when traditional water route mold is in order to improve quality problem that product is deformed by inhomogeneous cooling
Part molding deliberately extends cooling time, and not only improved effect is extremely limited for this measure, but also production efficiency is also decreased obviously.It passes
It unites in the impeller mold in water route, life cycle of the product was at 60 seconds or so, and sometimes in order to improve deformation of products, injection cycle is very
To more than 75 seconds or more, root it is estimated that all to spend in and cool down there are about 48-60 seconds time in whole cycle, plastic parts
Cooling cycle occupies 80% or so of entire molding cycle, it is therefore apparent that cooling time, cost was relatively high.
Invention content
The present invention in view of the above shortcomings of the prior art, provides a kind of plastic ＆ rubber blade mould conformal waterway cooling system,
Injection molding cycle that not only can be by product at traditional cooling scheme 60-70 seconds or so is reduced to 40-50 seconds or so, but also
The inferior rate that product occurs by inhomogeneous cooling can be reduced.

First, inventive die utilizes existing 3D metallic prints forming technique, the molding zero of processing plastic impeller mold
Part part.Water route can combine the moulds stream softwares such as Moldflow along product profile design, muscle position easily shrink position in this way
Analysis result, optimizes the shape of cooling water channel and shunting diameter, part mode position because iron charge is excessively thin and traditional cooling scheme without
When method is arranged, special-shaped profile-followed water route design scheme may be used, reinforce cooling effect.
Second, in terms of control of product quality, the mode part designed using profile-followed water route can make mode inside parts
It is cooling balanced, promote plastic ＆ rubber blade product quality, the appearance profile (end face run-out, circular runout) of product can be standard control
0.4mm processed or so, and also reach the 4mg.mm marks below of drawing requirement in terms of the quality control of the rotation imbalance of product
It is accurate.
Third is analyzed in terms of part processing, is processed the part with profile-followed water route using 3D printing technique, is reduced mode
Part machining link, the significant increase processing efficiency of part shorten the development cycle of mold, improve factory and produce mould per year
The production capacity of tool amount.
4th, it is analyzed from the effect of profile-followed water route application, the arrangement that water route can be balanced in mode can ensure in this way
Best formed product temperature, and the balanced regulation and control of mould temperature, injection molding that can be by product at traditional cooling scheme 60-70 seconds or so
Molding cycle is reduced to 40-50 seconds or so, and the production cycle saves 30% time using traditional cooling scheme, in the matter of product
In terms of amount, product can be reduced in the inferior rate occurred by inhomogeneous cooling, the significant increase production yield of product, and be residual
Substandard products are measured can also save with the cost of correction, be greatly saved plastic ＆ rubber blade production cost, improve the profit of product
Profit rate.
