[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0039] Please refer to Figures 1-4 , the present invention provides a technical solution for a two-station injection mold: a two-station injection mold, including a substrate 1, a lower mold assembly 2, an upper mold assembly 3, a moving assembly 4, a bracket 5 and a lifting cylinder 6. Specifically, the number of the lower mold assemblies 2 is two groups. The lifting cylinder 6 drives the upper mold assembly 3 to lift and move, and the moving assembly 4 drives the upper mold assembly 3, the bracket 5 and the lifting cylinder 6 to move left or right, and then moves the upper mold assembly 3 above a group of lower mold assemblies 2. The single upper mold assembly 3 sequentially performs mold closing and injection molding on the two groups of lower mold assemblies 2. Thus, when injecting into one group of lower mold assemblies 2, the molded parts in the other lower mold assembly 2 are removed. Such alternate operations reduce the time consumed for blanking.
[0040] The lower die assembly 2 includes a lower die base 21, a forming cavity 22, a positioning groove 23, a sliding column 24, a lifting plate 25, a ejector cylinder 26 and ejector pins 27. Specifically, when the ejector cylinder 26 contracts, it pulls the lifting plate 25 and multiple groups of ejector pins 27 downward until the top ends of the ejector pins 27 are adapted to the bottom end of the forming cavity 22. And after injection molding, the ejector cylinder 26 extends to push the lifting plate 25 and multiple groups of ejector pins 27 upward, and then the ejector pins 27 eject the molded part out of the forming cavity 22, thus facilitating the removal of the molded part.
[0041] The upper die assembly 3 includes an upper die base 31 and positioning columns 32. Specifically, when the upper die base 31 and the lower die base 21 are closed, multiple groups of positioning columns 32 are inserted into the interiors of multiple groups of positioning grooves 23, so that the upper die base 31 and the lower die base 21 are more precise after closing.
[0042] The moving assembly 4 includes a U-shaped seat 41, a screw 42, a moving seat 44, a servo motor 45 and a guide rod 43. Specifically, the servo motor 45 drives the screw 42 to rotate, so that the moving seat 44 moves left or right along the guide rod 43, and then the moving seat 44 drives the upper die assembly 3, the bracket 5 and the lifting cylinder 6 to move left or right.
[0043] In actual use of this double-station injection mold, the lifting cylinder 6 drives the upper die assembly 3 to move downward, and then the upper die assembly 3 and a set of lower die assemblies 2 are in a closed mold state, and then injection molding is carried out;
[0044] After injection molding, the lifting cylinder 6 drives the upper die assembly 3 to move upward, and the moving assembly 4 drives the upper die assembly 3, the bracket 5 and the lifting cylinder 6 to move until the upper die assembly 3 is directly above the second set of lower die assemblies 2, so that the lifting cylinder 6 drives the upper die assembly 3 and the second set of lower die assemblies 2 to close for injection molding. At this time, the operator can remove the molded part on a set of lower die assemblies 2;
[0045] Repeat the above operations in this way, so that double-station continuous injection molding can be realized.
