Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings.

The drawings are merely schematic illustrations of the present disclosure. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. It will be understood that the scale of the various components in the figures do not constitute limitations of the present disclosure.

As shown in fig. 1-2, the embodiment of the present disclosure provides an anti-collision structure of a mold insert, including a rear mold core 1, a rear mold insert 2, an insert cushion block 3, a push plate 4, and a base plate 5, wherein the rear mold core 1 and the push plate 4 are disposed in a through manner, the rear mold insert 2 is disposed in the rear mold core 1, a first positioning portion 31 and a second positioning portion 33 protruding from the upper and lower surfaces of the insert cushion block 3 are respectively disposed, a first positioning groove matched with the first positioning portion 31 is disposed at the bottom of the rear mold insert 2, a second positioning groove 51 matched with the second positioning portion 33 is disposed on the base plate 5, the push plate 4 encloses the rear mold core 1 and the insert cushion block 3 therein, a plurality of guide posts 6 are respectively disposed on the base plate 5, and the plurality of guide posts 6 are inserted into the rear mold insert 2 after passing through the insert cushion block 3.

The push plate 4 is provided with a first groove and a second groove which are arranged in a stepped manner, the rear mold core 1 is arranged in the first groove at the upper part, and the insert cushion block 3 is arranged in the second groove at the lower part.

The two sides of the insert cushion block 3 are provided with protruding holding parts 32, a side groove corresponding to the holding parts 32 is arranged in the second groove position, and the base plate 5 is provided with a guide needle 7 which penetrates through the holding parts 32 and is inserted into the rear mold core 1.
