Description
Technical field
The present invention relates to mould water channel modeling field, more particularly to a kind of method in dynamic creation mold cooling water road.
Background technology
Mould be in industrial production for being molded, the instrument of the batch shaping such as die casting, there is the type of shaping the inside of mould
Chamber, in the material injection mold cavity of thawing, internal material is solidified into product after mould cooling, opens mould taking-up shaping and produces
Product, shaping is completed.The material of mould is metal, waits the mould natural cooling time very long, so having made many in mould
Cooling water channel, for accelerating production efficiency.
Mould water channel for more preferable cooling effect, be with flowing water cooling, so one group of water channel by a water inlet and
One cooling water channel hole composition between delivery port, and water inlet and delivery port, because mold materials are metals, processing mold
The method in cooling water channel hole is bored with metal bit, and metal bit is straight, it is impossible to bore curved hole, drilling terminates rear water channel
The processing technology hole in hole is blocked with plug, leaves behind water inlet and delivery port, so each section of independent water channel, all with one
With drill bit drilling come opening, and one group of water route be made up of multiple independent water channels connections, so these drill bit imports are to want
Blocked with plug, a water channel can be, from any one of two of part opening drill, how to determine boring direction and boring point
Cost-effective could be critical., in mould inside, except water inlet and delivery port, water channel hole is or not the other parts of water channel hole
Cut is allowed, because in mould production, inside water channel is circulating water, if water channel hole has a cut, circulating water will be from broken
Mouth outflow, causes production to terminate.In addition, there is mismachining tolerance in water channel Drilling operation, so die cavity or mould in water channel and mould
Other parts will have safe distance, in order to avoid water channel cut during water channel hole machined.
Before processing mold cooling water channel, the drawing of the cooling water channel of mould is first designed.All it was in the past that 2d softwares draw water
Road drawing, 3d modeling softwares rise in recent years, 3d modeling softwares design is directly perceived, but position is numerous and diverse anyhow because of mould water channel,
It is distributed in the solid space of mould, because every group of water channel contains the water channel of varying number and diverse location, and each water channel
Want and there is safe distance in any face of the cooling part, so water channel is designed in 3d modeling softwares bothering very much.
Current water channel design modeling method is that the different sections inside one group of water channel are divided into independent water channel to be modeled respectively,
Because each section of water channel beginning and end position is different, height space is also different, so when drawing water channel, user elder generation mouse is specified
This section of water channel starting point coordinate (xyz three-dimensional coordinates) and terminal point coordinate (xyz three-dimensional coordinates), then with beginning and end the water channel mould
Type is created, because simply specifying beginning and end, the center section of the long strip type water channel model of establishment is likely to and cooling body
Other faces interfered, if to change the coordinate dimension of the water channel, it is necessary to user reassigns beginning and end, regeneration
Water channel, then whether the water channel interferes other faces with eye recognition.This method has the disadvantage that user's mouse can just be seen after specifying at 2 points
To model, have after model again by eye recognition, and determine whether to change coordinate position.After user creates one section of water channel, its
His section water channel equally wants user's mouse to specify beginning and end to create.Water channel hop count is more, operates very cumbersome, mouse point
Hit quantity very many.
Additionally, each section of water channel that above-mentioned existing method is obtained all is independent, the height of one of water channel is being adjusted
When, the height of other water channels will not change therewith, even if still needing individually tune in level other water channels with the water channel
Whole height, workload is big, cumbersome.
To sum up, how mouse position is obtained in real time, water channel, and real-time adjustment are generated and update in real time by the position of mouse
Be sequentially connected and level water channel highly, reduce the difficulty that 3d modeling softwares create water channel, it appears increasingly important.
