In order to achieve the above object, the technical solution of the present utility model is:

the utility model relates to a double-hole forming slide block mould, which comprises an inclined guide post, an inclined guide block, a slide block seat and a thimble; the lower part of the inclined guide post is movably arranged in a guide post hole of the sliding block seat in a penetrating way, the inner side wall of the inclined guide block is in sliding connection with the side wall of the sliding block seat in a groove block matching way, the outer end of the thimble is fixed at the inner end of the sliding block seat, and the inner end of the thimble extends into the cavity; the inclined guide post is a stepped cylinder with a thick upper part and a thin lower part, and the thick upper part of the inclined guide post is matched with the guide post hole of the slide block seat.

The inner side wall of the oblique guide block is provided with a guide strip protruding outwards along the oblique direction, and the guide strip is in sliding connection with a guide chute on the side wall of the sliding block seat.

The utility model also comprises a thimble pressing block; the ejector pin is arranged at the bottom of the sliding block seat in a penetrating way, the outer end of the ejector pin is propped against the ejector pin pressing block, and the ejector pin pressing block is fixed at the bottom of the sliding block seat.

The utility model also comprises a fixed template and a movable template; the fixed template and the movable template are combined together; the upper ends of the inclined guide posts and the inclined guide blocks are fixed on the fixed die plate, and the sliding block seat is in sliding connection with the movable die plate.

After the scheme is adopted, the die comprises the inclined guide post, the inclined guide block, the slide block seat and the ejector pin, wherein the inclined guide post and the inclined guide block drive the slide block seat to move so as to drive the ejector pin to loose core, and the slide block seat is in relay loose core by the inclined guide post and the inclined guide block, so that a larger loose core stroke can be realized, and the size of the die is smaller.

The utility model will be further described with reference to the drawings and the specific examples.

Detailed Description

As shown in fig. 2-7, the utility model discloses a double-hole forming slide block mold, which comprises a fixed mold plate 1, a movable mold plate 2, an inclined guide pillar 3, two inclined guide blocks 4, a slide block seat 5, a thimble 6 and a thimble pressing block 7.

The fixed template 1 and the movable template 2 are leaned together; the upper ends of the inclined guide posts 3 and the inclined guide blocks 4 are fixed on the fixed template 1, and the slide block seat 5 is in sliding connection with the movable template 2. The lower part of the inclined guide post 3 is movably arranged in a guide post hole 51 of the slide block seat 5 in a penetrating way, the inner side walls of the two inclined guide blocks 5 are respectively connected with the two side walls of the slide block seat 4 in a sliding way in a groove block matching way, the outer end of the thimble 6 is fixed at the inner end of the slide block seat 5, and the inner end of the thimble 6 extends into the cavity.

In this embodiment, the oblique guide post 3 is a stepped cylinder with a thick upper part and a thin lower part, and the thick upper part 31 of the oblique guide post 3 is matched with the guide post hole 51 of the slide block seat 5. The inner side wall of the oblique guide block 4 is provided with a guide strip 41 protruding outwards along the oblique direction, and the guide strip 41 is in sliding connection with a guide chute 52 on the side wall of the slide block seat 5. The thimble 6 is arranged at the bottom of the sliding block seat 5 in a penetrating way, the outer end of the thimble 6 is propped against the thimble pressing block 7, and the thimble pressing block 7 is fixed at the bottom of the sliding block seat 5.

The working principle of the utility model is as follows:

when the die is opened, the inclined guide post 3 and the inclined guide block 4 simultaneously drive the slide block seat 5 to move outwards, the slide block seat 5 drives the thimble 6 to core outwards, after a certain distance of core pulling, the thick section 31 on the inclined guide post 3 is separated from the guide post hole 51 of the slide block seat 5, and the guide strip 41 on the inclined guide block 4 continuously drives the slide block seat 5 to move outwards, so that complete core pulling is realized.

The foregoing description is only illustrative of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, i.e., the equivalent changes and modifications to the utility model as described in the claims and specification should be considered as falling within the scope of the utility model.
