Detailed Description
The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 7, an injection mold for an automobile fender of the present invention includes a fixed mold assembly 2, a movable mold assembly 3, and a feeding mechanism 4, the movable mold assembly 3 is movably disposed under the fixed mold assembly 2 and forms a product cavity between the fixed mold assembly 2 and the movable mold assembly 3 when the fixed mold assembly 2 is attached to the movable mold assembly 3, the feeding mechanism 4 has at least a first feeding state and a second feeding state, and the feeding mechanism 4 includes: the hot runner 5 is arranged on the fixed die assembly 2, a feed inlet 6 communicated with the hot runner 5 is arranged on the fixed die assembly 2, and a first sub-runner 7 and a second sub-runner 8 which are connected with the hot runner 5 and the product cavity are arranged at the lower part of the fixed die assembly 2; a first valve needle 9 and a second valve needle 10 movably arranged in the hot runner 5 and respectively movably abutted against the first sub-runner 7 and the second sub-runner 8; when the feeding mechanism 4 is in a first feeding state, the first valve needle 9 is abutted against the first sub-runner 7, the hot runner 5 is blocked from being communicated with the product cavity through the first sub-runner 7, and the hot runner 5 is communicated with the product cavity through the second sub-runner 8; when the feeding mechanism 4 is in the second feeding state, the second valve needle 10 abuts against the second sub-runner 8, the hot runner 5 is blocked from communicating with the product cavity through the second sub-runner 8, and the hot runner 5 communicates with the product cavity through the first sub-runner 7.
The hot runner 5 is heated to ensure that the plastic of the runner and gate remains molten. Because the heating rod and the heating ring are arranged near the runner or in the center of the runner, the whole runner from the nozzle outlet of the injection molding machine to the feed inlet 6 is in a high-temperature state, so that plastics in the runner are kept molten, the runner is generally not required to be opened to take out the solidified material after the machine is stopped, and the runner 5 is only required to be heated to the required temperature during the machine is started. Thus, the hot runner 5 process is sometimes referred to as a hot header system, or as runner-less molding.
During injection molding production, an injection mold is mounted on the injection molding machine, the movable mold assembly 3 is driven to move relative to the fixed mold assembly 2 through a driving structure on the injection molding machine, mold opening and closing actions of the injection mold are completed, during injection, the injection molding machine injects molten plastics into the hot runner 5 from the feed inlet 6, the plastics entering the hot runner 5 enter different feeding sequences according to different feeding states of the feeding mechanism 4 and different positions entering a product cavity, and the feeding states of the feeding mechanism 4 can be two or more and mainly described for the conditions of the two feeding states in the scheme.
According to the design of the fender, the second sub-runner 8 and the first sub-runner 7 are respectively arranged on the fixed mold component 2 and are positioned on the upper part of the fender accommodating cavity 1, and the first sub-runner 7 is positioned on the upper part of the other main body part of the fender. Because if the mud guard structure is more complicated and the outer wall of the containing cavity 1 is fed, the feeding time of the structure is too long due to the fact that the outer side wall of the containing cavity 1 is complicated, the heat dissipation of the plastic in a molten state is faster, and the phenomenon of welding marks or material taking occurs on the mud guard.
It should be noted that the number of product cavities can be determined according to the size of the mud guard and the size of the injection mold, and can be one, two or more, and the present solution is mainly described with respect to the case of one product cavity.
