Detailed Description

Example (b):

the present invention will be described in further detail with reference to the accompanying fig. 1-4.

A fog lamp shade mould of an automobile comprises a fixed mould 1, a movable mould 2 is inserted into the surface of the fixed mould 1, guide holes 3 are fixedly formed in the surfaces of the fixed mould 1 and the movable mould 2, and the four guide holes 3 are symmetrically distributed by taking the axes of the fixed mould 1 and the movable mould 2 as the center;

furthermore, by arranging the guide hole 3, when the die is used, once the guide post is worn, a new guide post can be directly replaced, the guide hole 3 is milled and reused, and the die assembly precision is kept, so that the problem that the guide post and the guide sleeve of the existing die are inconvenient to replace because the guide post is directly and fixedly connected with the surface of the fixed die 1 is solved;

as shown in fig. 1 and fig. 3-4, a guiding and positioning groove 4 is fixedly arranged on the surface of a fixed mold 1, six guiding and positioning grooves 4 are symmetrically distributed by taking the axis of the fixed mold 1 as the center, a slide block 5 is connected on the inner wall of the guiding and positioning groove 4 in a sliding manner, a convex part 21 is arranged on the surface of a movable mold 2, six convex parts 21 correspond to the guiding and positioning grooves 4, the surfaces of the convex parts 21 are respectively inserted and connected with the inner wall of the guiding and positioning groove 4 and the surface of the slide block 5 in a sliding manner, a mold cavity 101 is arranged on the inner wall of the fixed mold 1, two mold cavities 101 are symmetrically distributed by taking the axis of the fixed mold 1 as the center, functional blocks 102 are fixedly connected on the inner wall of the fixed mold 1, six functional blocks 102 are distributed in an annular array by taking the axis of the mold cavity 101 as the center, the surface of one end of the functional block 102 is in, the surface of the core 201 is inserted with the surface of the functional block 102, the surface of the movable mold 2 is fixedly provided with an injection molding hole 202, the surface of the lower part of the fixed mold 1 is fixedly provided with a thimble hole 103, and the thimble holes 103 are uniformly distributed on the lower surface of the fixed mold 1;
