Molding machine platform can also save considerable cost on selecting.
On article manufacturing cycle, because being not necessarily to be opened rotating mould completely in production of articles, die sinking rotation completely is saved
The time of revolving die tool, product molding period are substantially shorter, and promote the production efficiency of product, and the promotion of production efficiency is also just meaned
Production of articles greatling save on time cost.
For production of articles stability, conventional double-color mold needs to be opened completely after the completion of one penetrates, and allows injection molding machine
Pivoting mechanism driven mold carries out 180 ° of rotations, and one at this time penetrates product and generally rotates in dynamic model side with one piece of mold, rotates through
Product inevitably by shake is fallen or is misplaced because mold is rotated in journey, if there is above-mentioned condition processing not in time, gently product is not
Qualification, heavy then mold pressing mold cause burn failure, increase the delay of repair a die cost and production of articles duration on foot, and use duplexing bit-type
The double-color mold of cored structure and the design of double-station slide block mechanism need to only be opened on demand then without being opened completely after product one is penetrated
Mould respective distance, double-station sliding block and duplex core move to setting position, then under the driving of oil cylinder and its attachment device
Directly molding carries out biphasic injection, reduces the various risks generated by die sinking rotation, while also improving the quality of product, saves
About a large amount of cost.
It is analyzed from mould development angle, the present invention borrows the product case lifted to have particularity, can from the following figure two
Out, it is annular feature that product second, which injects glue at the both ends for having sliding block, and conventional double-color mold arrangement is then cavity side mode
Moulding section is constant, and core side is changed, and second penetrates the circular contour of the product nothing in conventional rotating bichromal mold
Method realizes rotary injection, and uses double-station core mechanism and the double-color mold of double-station slide block mechanism that above-mentioned ask then is not present
