Detailed Description

The present invention is further illustrated by the following examples, which should not be construed as limiting the scope of the invention.

Example (b): refer to FIGS. 1-2

The utility model provides a prevent equipotential mould structure that mold insert card was hindered, includes roof pressing plate 1, cover half 2,

mold insert

3, 2 slider 4, movable mould 5, moulding foot 6, movable mould press plate 7 and thimble board 8, is provided with the thimble on the thimble board 8. The 2 slide blocks 4 are symmetrically arranged on two sides of the movable mold 5 in a sliding mode, and the slide blocks 4 are arranged on two sides of the movable mold 5 in a sliding mode, referring to Chinese patent CN 201810738862.2, through arranging the inclined guide posts and the guide rails in sliding fit with the slide blocks, the slide blocks 4 on two sides of the movable mold 5 can slide back and forth in the process of mold closing and mold stripping.

The movable die 5 is provided with insert grooves 10 and a movable die core 9 arranged in the insert grooves 10, and as can be seen from a comparison of fig. 2, 2 rows of insert grooves 10 are arranged on the movable die 5, a straight groove 11 extending towards the direction of the slide block 4 is arranged on the side portion of each insert groove 10, and the extending directions of the straight grooves 11 on the side portions of the 2 rows of insert grooves 10 are opposite, that is, the straight grooves 11 on the side portions of the 2 rows of insert grooves 10 extend towards the direction of the slide block 4 on the opposite two sides of the movable die 5 respectively. The slide block 4 is provided with a slide block core 401 matched with the movable mold core 9 and a slide block matched with the straight groove 11 in a sliding way. It can be seen that the number of the slide blocks on the slide 4, the movable mold core 9, the slide core 401, the insert groove 10 and the straight groove 11 is the same.

The side part of the insert 3 is provided with a positioning lug 301, the width of the positioning lug 301 is slightly smaller than that of the straight groove 11, the insert 3 is sleeved on the outer side of the movable mold core 9, and one end, far away from the insert 3, of the positioning lug 301 slightly extends into the insert groove 10, so that the insert 3 is not easy to be clamped in the installation process, one end of the positioning lug 301 slightly horizontally extends into the insert groove 10, a certain positioning effect is achieved on the position of the positioning lug 301, and sliding deviation is avoided. The sliding blocks on the sliding block 4 are arranged in the straight grooves 11 at the side parts of the corresponding insert grooves 10, and can slide back and forth along the straight grooves 11 in the horizontal direction.

When the mold is closed, the sliding block on the slide block 4 slides towards the insert 3 along the straight groove 11, and after the mold closing is completed, the opening of the slide block core 401 is butted with the opening of the movable mold core 9, and the sliding block on the slide block 4 is in close contact with the surface of the positioning bump 301 on the side of the insert 3, so that the straight groove 11 on the side of the insert groove 10 is completely closed. And (3) opening the mold after the injection molding is finished, enabling the sliding blocks 4 on the two sides of the movable mold 5 to slide outwards, driving the sliding blocks on the sliding blocks 4 to be separated from the surfaces of the positioning bumps 301 on the side parts of the mold inserts 3, and then ejecting out the product.

The statements in this specification merely set forth a list of implementations of the inventive concept and the scope of the present invention should not be construed as limited to the particular forms set forth in the examples.
