Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a make ball and glue mould of assembly, including last mould 1 and lower mould 2.

Referring to fig. 1 and 2, the upper die 1 is provided with a chute 11 in the circumferential direction of the end surface facing the lower die 2, the cross section of the chute 11 is semicircular, the upper die 1 is provided with a plurality of limiting mechanisms 3 at the chute 11, and the plurality of limiting mechanisms 3 are uniformly arranged along the circumferential direction of the chute 11 at intervals.

Referring to fig. 2 and 3, the limiting mechanism 3 includes two clamping strips 31, a fixing groove 32 is formed between the two clamping strips 31, and first round corners 311 are disposed at two ends of each clamping strip 31. In the present embodiment, three limit mechanisms 3 are provided in total.

Referring to fig. 2 and 4, the bottom of the upper die 1 in the depth direction of the sliding groove 11 is provided with first clamping holes 12 corresponding to the limiting mechanisms 3 one by one and second clamping holes 13 corresponding to the limiting mechanisms 3 one by one. The first clamping hole 12 is formed in the upper die 1 at the position of the limiting mechanisms 3, and the second clamping hole 13 is formed between the two limiting mechanisms 3.

Referring to fig. 4 and 6, the lower die 2 has a slide 21 that is engaged in the slide groove 11 at one end toward the upper die 1.

Referring to fig. 4 and 5, the slide bar 21 is provided with a clamping groove 22 at a position corresponding to the clamping bar 31 for the clamping bar 31 to slide in, when the slide bar 21 is placed in the sliding groove 11, the upper die 1 is rotated to enable the slide bar 21 to be clamped in the upper die 1 at the position of the limiting mechanism 3, so that the upper die 1 and the lower die 2 are relatively fixed, and the probability that the end surface of the upper die 1 and the end surface of the lower die 2 are difficult to attach is reduced.

Referring to fig. 4, 7 and 8, the slide bar 21 is provided with a plunger hole 211, and the ball-end spring plunger 23 is installed in the plunger hole 211, and the ball-end spring plunger 23 further includes a plunger housing 231, a plunger ball 232 and a plunger spring 233. When the plunger ball 232 is caught in the first catching hole 12, the slide bar 21 is scratched into the slide groove 11 at the catching bar 31, thereby reducing the probability of generating a gap between the upper and lower dies 1 and 2.

Referring to fig. 4, 7 and 8, when the plunger ball 232 is snapped into the second snap hole 13, the slide bar 21 and the snap bar 31 are staggered, so that the upper die 1 is more convenient to fall off from the lower die 2, and the difficulty in demolding between the upper die 1 and the lower die 2 is reduced.

Referring to fig. 4 and 5, a guide corner 111 is formed at the edge of the upper die 1 at the sliding groove 11, and the slide bar 21 is more smoothly clamped into the sliding groove 11 due to the guide corner 111, so that the mounting difficulty of the upper die 1 at the lower die 2 is reduced.

Referring to fig. 3 and 5, in order to make the slider 21 more smoothly when being clamped into the position limiting mechanism 3, the second rounded corners 213 are respectively formed at the two ends of the slider 21, and the slider 21 is more conveniently clamped in the sliding groove 11 due to the arrangement of the first rounded corners 311 and the second rounded corners 213.

The implementation principle of the embodiment is as follows:

1. the sliding strip 21 is scratched to the position, where the upper die 1 is located on the clamping strip 31, of the upper die 1, so that the probability that the upper die 1 and the lower die 2 are difficult to attach due to accumulation of debris at a lower touch position is reduced, and therefore the probability that rubber leaks from the upper die 1 and the lower die 2 when the rubber is injected between the upper die 1 and the lower die 2 due to gaps generated between the upper die 1 and the lower die 2 is facilitated;

2. the plunger ball 232 is clamped into the first clamping hole 12, so that the probability of deviation of the slide bar 21 at the sliding groove 11 is reduced, the rotating position of the slide bar 21 at the sliding groove 11 is determined, the plunger ball 232 is clamped into the second clamping hole 13, the position of the slide bar 21 at the sliding groove 11 is facilitated, the upper die 1 and the lower die 2 are more convenient to separate, and the difficulty in dismounting between the upper die 1 and the lower die 2 is reduced; 3. the arrangement of the first round angle 311 and the second round angle 213 facilitates the slide bar 21 to be clamped into the card bar 31 when the slide bar 21 slides in the sliding slot 11, thereby reducing the probability of collision between the slide bar 21 and the card bar 31.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
