Description
Technical Field
The utility model relates to the technical field of injection molding, in particular to a runner structure for high-viscosity plastic injection molding.
Background
In the existing plastic injection molding process, in order to improve the injection molding efficiency, a plurality of circulation structures are opened in a common injection molding structure or a mold, so that the simultaneous multi-channel injection molding is realized, and a plurality of products are molded simultaneously.
However, in order to satisfy the requirement of multi-channel injection molding and simultaneous molding, it is necessary that the molten plastics in each channel can reach the designated molding pattern simultaneously, and the injection molding speeds are consistent to ensure that a plurality of products are molded simultaneously, so that the problem of poor injection molding speed can be avoided, and the phenomena of air breakage and crack on the surface of the product caused by the final demolding of the product with a slow injection molding speed can be avoided. For the injection molding of the plastic with lower viscosity, because the resistance in the flowing process is small, the speed difference can not occur as long as the strokes are the same, but for the high-viscosity plastic, the speed difference problem is more serious, the crack phenomenon is more frequent, the product attractiveness is influenced, and the quality is reduced.
To this end, a runner structure for injection molding of high-viscosity plastics is proposed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a runner structure for high-viscosity plastic injection molding, which can ensure that a plurality of products are simultaneously injection molded so as to solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme: a runner structure for high-viscosity plastic injection molding comprises a mold main body, wherein a raw material injection opening is formed in the mold main body and is located in the center of the mold main body, two ends of the raw material injection opening are connected with conduction runners, the conduction runners are communicated with four diversion runners, the four diversion runners are uniformly arranged at the end parts of the conduction runners, and an injection molding hole is formed in the end part of each diversion runner;
an accelerating area is arranged between the two shunting flow channels far away from the end part of the conducting flow channel.
Preferably, the accelerating area is arc-shaped, the radius of the arc is 1cm, and the radian is 90 degrees.
Preferably, the acceleration zone is triangular in shape.
Preferably, the number of the raw material injection ports is two, and a main injection port is communicated between the two raw material injection ports and is positioned at the center of the mold main body.
Compared with the prior art, the utility model has the beneficial effects that: the acceleration area is added, so that the injection speed in the four injection holes far away from the raw material injection opening is consistent with that in the four injection holes close to the raw material injection opening, and a plurality of products are guaranteed to be simultaneously subjected to injection molding.
