[0014] Beneficial effects:

[0015] (1) The composite mechanism of the slider with the side slider has a paddle and a guide block arranged in the mechanism. The oil cylinder drives the third slider to move through the connecting member. The third slider cooperates with the guide slider through the paddle. The synchronous movement of the first slider and the second slider is achieved through the transmission of force. The force is transmitted mechanically, which saves the oil cylinder, connecting member, oil pipe, fixed seat, travel switch and other parts required for the movement of the first slider and the second slider, reduces the mold production time and cost, and also reduces the risk of mold damage. The paddle and the guide block allow the three groups of sliders to constrain each other, thereby improving the stability of the three groups of sliders. There is no need to design conventional pressure strips on the left and right sides of the traditional slider, and there is no need to set additional inclined guide columns.

[0016] (2) The composite mechanism of the slider with the side slider is provided with a third slider in the mechanism. The third slider provides driving force for the first slider and the second slider through the paddle, so as to facilitate the first slider and the second slider to achieve disengagement. The composite mechanism can shorten the production cycle of the injection mold for injection molding products, effectively improve the injection molding production efficiency, and has fewer components, thereby reducing the workload of mold disassembly and assembly.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] refer to Figure 1-Figure 5 , the present invention provides two technical solutions:

[0026] The first embodiment: a composite mechanism of a slider with a side slider, including a rear mold 2, a cylinder pad 11 is fixedly connected to the middle of the front side of the rear mold 2, a cylinder 10 is fixedly connected to the cylinder pad 11, a connecting meson 12 is installed at the rear extension end of the cylinder 10, three groups of T-shaped guide sliders 6 are installed on the upper side of the rear mold 2, and the upper ends of the three groups of T-shaped guide sliders 6 are respectively slidably connected to the first slider 3, the second slider 13, and the third slider 14, and the upper side of the rear mold 2 is provided with a rear end corresponding to the first slider 3, the second slider 13, and the third slider 14. A middle air outlet 1 is provided, a connecting meson 12 is fixedly connected to a third slider 14, a paddle 9 is installed on the upper side of the third slider 14 and is slidably connected to the inner sides of the first slider 3 and the second slider 13 respectively, two sets of guide sliders 5 are installed on the inner sides of the first slider 3 and the second slider 13, a first wear-resistant plate 4 and a second wear-resistant plate 8 are respectively provided on the upper front side and the bottom of the first slider 3, the second slider 13 and the third slider 14, and an extended water nozzle 7 is installed on the lower front end of the first slider 3, the second slider 13 and the third slider 14;

[0027] Four through holes are arranged on the inner side of the middle air outlet 1, and the two adjacent through holes in the middle of the middle air outlet 1 have the same ejection direction, and the through holes on both sides of the middle air outlet 1 have opposite molding directions and are not consistent with the molding direction of the two vacancies in the middle; the guide slider 5 is made of aluminum bronze, the T-shaped guide slider 6 is made of high-strength brass insert graphite material, and the paddle 9 is made of Cr12 material; the bottom of the first slider 3, the second slider 13, and the third slider 14 are all provided with two groups of T-slots 16 that are close to the rear mold 2, and the T-shaped guide slider 6 is slidably connected to the T-slot 16; the extended water nozzle 7 is connected to the external water pipe, and the inner side of the cylinder pad 11 is provided with a movable groove near the end of the extended water nozzle 7, and the first slider 3, the second slider 13, and the third slider 14 are cooled by supplying water to the extended water nozzle 7; the first wear-resistant plate 4 is located on the rear side of the guide slider 5, and the first slider 3 and the third slider 14 are symmetrically arranged on the rear mold 2 relative to the second slider 13;

[0028] The oil cylinder 10 is horizontally arranged on the oil cylinder pad 11 along the Y axis, and the rear sides of the first slider 3, the second slider 13, and the third slider 14 are all installed with mushroom heads 15 for positioning; the oil cylinder 10 drives the third slider 14 to move through the connecting meson 12, and the third slider 14 cooperates with the guide slider 5 through the paddle 9, and realizes the synchronous movement of the first slider 3 and the second slider 13 through the transmission of force. The force is transmitted by mechanical means, which saves the oil cylinder 10 and the connecting meson 12 required for the movement of the first slider 3 and the second slider 13, reduces the mold production time and cost and damage risk, and the paddle 9 and the guide slider 5 allow the first slider 3, the second slider 13, and the third slider 14 to constrain each other, thereby improving the stability of the three groups of sliders;

[0029] The second implementation mode is mainly different from the first implementation mode in that:

[0030] The cylinder pad 11 is located at the front side of the third slider 14 and is used to limit the third slider 14. The inner sides of the second slider 13 and the third slider 14 are provided with sliding grooves that are slidably connected to the two sides of the paddle 9. The two groups of guide sliders 5 are respectively located at the two ends of the paddle 9 and fit with the paddle 9. The paddle 9 and the third slider 14 are perpendicular to each other. The third slider 14 provides driving force for the first slider 3 and the second slider 13 through the paddle 9, which is convenient for driving the first slider 3 and the second slider 13 to achieve disengagement, so that the device has fewer components and reduces the workload of mold disassembly and assembly.

[0031] refer to Figure 6:The movement of the third slider 14 and the left and right sliders follows the triangle principle. The triangle in the figure is the linkage principle of the third slider 14 and the first slider 3 (the third slider 14 is consistent with the principle of the second slider 13, unit: mm): The line segment 100 is the tripping direction and stroke of the third slider 14 (both determined by the product) combined with the transmission method of the mechanism force. Because the paddle 9 and the third slider 14 are perpendicular, draw another line segment perpendicular to the line segment 100 as the short right-angled side of the triangle, and the length is temporarily unknown. The hypotenuse of the triangle is the demoulding direction of the first slider 3, and the starting point is consistent with the starting point of the third slider 14. In this way, the hypotenuse of the triangle intersects with the short right-angled side, and the length of the short right-angled side 37.39 is obtained as the effective action length of the paddle 9 and the guide slider 5, and the hypotenuse length 106.76 is used as the tripping stroke of the first slider 3. Inspection: If the tripping of the first slider 3 106.39 does not reach the tripping distance, the tripping stroke of the third slider 14 should be increased accordingly. In this way, the tripping stroke of the first sliding block 3 will be increased, and the short right-angle side will also be lengthened.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When in use, after the external injection molding mechanism completes the injection molding, the upper side of the rear mold 2 is opened, and the oil cylinder 10 is started. The oil cylinder 10 drives the third slider 14 and the T-shaped guide slider 6 to slide along the T-shaped groove 16 through the connecting meson 12. The third slider 14 transmits the force of the first slider 3 and the second slider 13 through the paddle 9 and the two groups of guide sliders 5 on the first slider 3 and the second slider 13, so that the first slider 3 and the second slider 13 slide along the corresponding T-shaped groove 16 through the T-shaped guide slider 6 on the lower side of the air, so as to realize rapid demoulding, and the external ejection mechanism ejects the injection molded part from the middle air outlet 1, and then removes the injection molded part and resets the needle plate, so that the oil cylinder 10 drives the third slider 14, the paddle 9, the guide slider 5, the first slider 3, and the second slider 13 to reset through the connecting meson 12, and the rear mold 2 is re-molded;

[0034] After the film is completed, the mushroom head 15 on the rear side of the first slider 3, the second slider 13, and the third slider 14 is inserted into the injection molding mechanism to achieve interlocking and improve the stability of the device during the injection molding process. During the movement of the first slider 3, the second slider 13, and the third slider 14, the cylinder 10 provides driving force for the slider. Before the three groups of sliders are moved, the entire rear mold 2 is in a stationary state, and the middle air outlet 1 remains on the side of the rear mold 2, so the middle air outlet 1 is also in a stationary state at this time. The paddle 9 fixed on the third slider 14 moves synchronously with the third slider 14 and provides driving force for the movement of the first slider 3 and the second slider 13. The guide slider 5 on the first slider 3 reduces the sliding friction while also bearing the effect of force, and the paddle 9 needs to bear the shear force required to drive the first slider 3.
