Detailed Description
The utility model provides a cover body injection mold. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
As shown in FIGS. 4 and 5, a cut portion 11 is provided on an outer wall of a cover 10, and the cut portion 11 is provided with a plurality of ribs 12 for increasing a frictional force.
As shown in fig. 1 to 3, the injection mold of the present invention includes a first mold base 1 and a second mold base 2 that are capable of relative opening and closing displacement. Namely, the first die holder 1 and the second die holder 2 have relative opening and closing operation displacement.
Wherein, be equipped with a plurality of model cavities 3 on the first die holder 1, be equipped with in arbitrary model cavity 3 and be used for the fashioned tangent plane type portion 4 of tangent plane portion 11, be equipped with in the tangent plane type portion 4 and be used for the fashioned a plurality of muscle body type grooves 5 of muscle body.
A plurality of model blocks 6 which are in one-to-one correspondence with the model cavities 3 are arranged on the second die holder 2, model surfaces 7 which are matched with the section-shaped parts 4 are arranged in the model blocks 6, and convex rib bodies 8 which are in one-to-one correspondence with the rib-shaped grooves 5 are arranged on the model surfaces 7.
