[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mold zero-angle slider clamping mechanism includes a front mold core 1 and a rear mold core 2. The adjacent surfaces of the front mold core 1 and the rear mold core 2 are both provided with a slide groove 8, and a slider group 12 is slidably installed inside the slide groove 8;

[0023] The slider group 12 includes a slider 1 3, a slider 2 4, a slider 3 5 and a slider 4 6. The slider 1 3 is internally plugged with a first guide post 9. The slider 3 5 and the slider 4 6 are slidably mounted in the row slots 8 on both sides of the top of the rear mold core 2, and the slider 3 5 and the slider 4 6 are internally plugged with a second guide post 10.

[0024] The rear mold insert 7 is detachably installed inside the rear mold core 2, and the first guide column 9 and the second guide column 10 are respectively installed on the top and both sides of the rear mold insert 7. A positioning pin 11 runs through the interior of the rear mold insert 7. The length of the positioning pin 11 is smaller than the second guide column 10. The positioning pin 11 and the slider three 5 and the slider four 6 are plug-in arranged.

[0025] In this embodiment, the rear mold insert 7 is first installed inside the rear mold core 2, and then the rear mold insert 7 is installed with the first guide column 9 and the second guide column 10 respectively. When the mold needs to be closed, the slider three 5 and the slider four 6 are inserted into the second guide column 10, and gradually closed toward the middle of the rear mold insert 7 through the second guide column 10 and the positioning pin 11 passing through the inside, and then the slider two 4 is first placed in the sliding groove 8 on the rear mold core 2, and finally the front mold core 1 is covered and the slider one 3 is moved downward along the first guide column 9 to complete the mold closing. The left and right side sliders are positioned by making positioning pins 11 on the rear mold core 2 to ensure that the sliders are prevented from breaking when moving at zero angle, and the relative position of the sliders between the mold cores moves, thereby effectively avoiding the risk of mold collision.

[0026] As an implementation method, Figure 1 , Figure 2 and Figure 3 As shown, the length of the second guide column 10 is greater than that of the first guide column 9, and the second guide column 10 and the first guide column 9 are vertically arranged, and the second guide column 10 and the positioning pin 11 are vertically arranged in parallel.

[0027] In this embodiment, the length of the second guide column 10 is greater than that of the first guide column 9, the interior of the slider 1 3 in the slider group 12 corresponds to the first guide column 9, and the interiors of the sliders 3 5 and 4 6 in the slider group correspond to the second guide column 10, thereby assisting the installation between the sliders and the mold core.

[0028] As an implementation method, Figure 4 As shown, the first guide column 9 and the second guide column 10 are both T-shaped structural members.

[0029] In this embodiment, the first guide column 9 and the second guide column 10 of the T-shaped structural member are used to correspond to the slider 1 3, the slider 3 5 and the slider 4 6 respectively, so as to prevent shaking during the moving mold closing process and affect the mold closing accuracy.

[0030] As an implementation method, Figure 2 and Figure 3 As shown, the slider three 5 and the slider four 6 are both provided with grooves corresponding to the slider two 4, and the slider two 4 is clamped between the row slot 8 and the grooves.

[0031] In this embodiment, after the slider three 5 and the slider four 6 are respectively combined with the second guide column 10 and the positioning pin 11, the grooves on the slider three 5 and the slider four 6 are used to clamp the slider two 4 in the row groove 8 and the groove to ensure the mold closing action of the slider two 4.

[0032] As an implementation method, Figure 3 and Figure 4 As shown, both ends of the positioning pin 11 extend into the row position slot 8, and the slider three 5 and the slider four 6 are arranged in a mirror image.

[0033] In this embodiment, both ends of the positioning pin 11 extend into the row groove 8. The positioning pin 11 is shorter than the second guide column 10 and is doubly parallel to the second guide column 10, which can improve the stability of the slider three 5 and the slider four 6 during the direct insertion process.

[0034] As an implementation method, Figure 2 , Figure 3 and Figure 4 As shown, the interiors of the slider three 5 and the slider four 6 are respectively provided with sliding grooves corresponding to the second guide column 10 and the positioning pin 11.

[0035] In this embodiment, the slider three 5 and the slider four 6 are inserted into the second guide column 10. After being inserted through the second guide column 10, the slider three 5 and the slider four 6 move while the positioning pin 11 passing through the inside is inserted, and gradually closes toward the middle of the rear mold insert 7 in the horizontal direction to avoid mold collision.

[0036] Working principle: When in use, first install the rear mold insert 7 inside the rear mold core 2, and then install the rear mold insert 7 with the first guide column 9 and the second guide column 10 respectively. When the mold needs to be closed, insert the slider 3 5 and the slider 4 6 into the second guide column 10. After the second guide column 10 is inserted, the slider 3 5 and the slider 4 6 move while inserting the positioning pin 11 that penetrates the inside, and gradually close to the middle of the rear mold insert 7 in the horizontal direction;

[0037] Then place the slider 2 4 in the row slot 8 on the rear mold core 2, and finally cover the front mold core 1 and move the slider 1 3 downward along the first guide column 9 to complete the mold closing. By making positioning pins 11 on the rear mold core 2 to position the sliders on the left and right sides, it is ensured that the sliders move in relative positions between the mold cores, thereby effectively avoiding the risk of mold collision.
