Description
Technical Field
The invention relates to the field of mold water channel modeling, in particular to a method for dynamically creating a mold cooling water channel.
Background
The mould is a tool for batch forming such as injection molding, die casting and the like in industrial production, a cavity for forming is arranged in the mould, melted materials are injected into the cavity of the mould, the materials in the mould are solidified into products after the mould is cooled, the mould is opened, the formed products are taken out, and the forming is finished. The material of the mould is metal, and the time for waiting for the natural cooling of the mould is very long, so a plurality of cooling water channels are manufactured in the mould for accelerating the production efficiency.
The mould water channel is cooled by flowing water for better cooling effect, so a group of water channels consists of a water inlet, a water outlet and a cooling water channel hole between the water inlet and the water outlet, because the mould material is metal, the method for processing the mould cooling water channel hole is to use a metal drill bit to drill, the metal drill bit is straight and can not drill a bent hole, after the drilling is finished, a processing process hole of the water channel hole is blocked by a plug, only the water inlet and the water outlet are left, each section of independent water channel is provided with an opening drilled by the drill bit, and a group of water channels are formed by connecting a plurality of independent water channels, so the inlets of the drill bits are blocked by plugs, one water channel can be drilled by the openings at any one of two ends of a part, and the key is that the cost can be saved by determining the drilling direction and the drilling point. The other parts of the water channel hole are all inside the die, and the water channel hole is not allowed to be broken except for a water inlet and a water outlet, because in die production, flowing water is inside the water channel, and if the water channel hole is broken, the flowing water flows out from the broken opening, so that production is stopped. In addition, the processing error exists in the drilling processing of the water channel, so the water channel has a safe distance with a die inner cavity or other parts of the die, and the water channel is not broken when the water channel hole is processed.
Before the cooling water channel of the mold is processed, a drawing of the cooling water channel of the mold is designed. In the past, 2d software drawing water channel drawings are adopted, 3d modeling software is raised in recent years, 3d modeling software is designed intuitively, but water channels of a mold are complicated in horizontal and vertical positions and distributed in a three-dimensional space of the mold, and each water channel contains water channels with different numbers and different positions, and each water channel has a safe distance from any surface of a cooling part, so that the water channel design in the 3d modeling software is very troublesome.
The existing water channel design modeling method is that different sections in a group of water channels are divided into independent water channels for modeling respectively, because the starting point and the end point of each section of water channel are different in position and height space, when the water channel is drawn, a user firstly designates the starting point coordinate (xyz three-dimensional coordinate) and the end point coordinate (xyz three-dimensional coordinate) of the section of water channel by a mouse, and then creates a water channel model by the starting point and the end point, because the starting point and the end point are only designated, the middle part of the created long strip-shaped water channel model is probably interfered with other surfaces of a cooling body, if the coordinate size of the water channel is modified, the user needs to designate the starting point and the end point again to regenerate a water channel, and then the human eyes are used for identifying whether the water channel interferes with other surfaces. The method has the disadvantages that the user can only see the model after the mouse designates two points, and the model is recognized by human eyes after the model is existed, and whether the coordinate position is modified or not is determined. After a user creates a channel, other channels are created by specifying a starting point and an end point by the user mouse. The number of water channel sections is large, the operation is very complicated, and the number of mouse clicks is large.
In addition, each section of water channel obtained by the conventional method is independent, the height of other water channels cannot be changed when the height of one water channel is adjusted, and even if the height of other water channels at the same height as the water channel is still required to be adjusted independently, the workload is large, and the operation is complicated.
In conclusion, how to obtain the position of the mouse in real time, generate and update the water channel in real time according to the position of the mouse, adjust the heights of the water channels which are sequentially connected and have the same height in real time, and reduce the difficulty of creating the water channel by 3d modeling software is particularly important.
