[0034] like Figures 1 to 8 As shown, an embodiment of the utility model provides an injection molding device for silicone parts, including a base 1, a mounting frame 5 is provided on the top, an injection molding mechanism 6 is provided at the bottom of the mounting frame 5, a molding cylinder 10 is provided on the base 1 opposite to the injection molding mechanism 6, the base 1 is provided with a through hole 11 connected to the molding cylinder 10, two baffles 13 are relatively slidably arranged at the bottom of the base 1, and are configured to block the through hole 11, sliders 24 are relatively provided on both sides of the two baffles 13, a slide groove 4 for the slider 24 to slide is provided on the base 1, and a driving component 9 for driving the two sliders 24 to slide relative to each other is provided on the base 1.

[0035] Specifically, the driving assembly 9 drives the two baffles 13 to move relatively away from each other so that they no longer block the through hole 11, thereby facilitating the discharge and collection of the silicone parts in the molding cylinder 10 and avoiding the silicone parts from being damaged during collection. This solves the problem that in the existing silicone parts injection molding device, the motor 91 drives the mold to rotate to fit with the rubber support plate 21, and the product inside the mold is prone to falling out prematurely, thereby causing the product to not fall accurately into the material receiving box.

[0036] It should be noted that the injection molding mechanism 6 is a prior art, and this embodiment is intended to facilitate the collection of the molded silicone parts.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the driving assembly 9 includes two fixed plates 92, which are relatively fixed at the bottom of the base 1, and a double-headed screw 93 is rotatably connected between the two fixed plates 92. The double-headed screw 93 is driven by a motor 91, and the motor 91 is fixed at the bottom of the base 1. The sliders 24 on the two baffles 13 are respectively relatively sleeved and threadedly connected to the two ends of the double-headed screw 93, so that when the double-headed screw 93 rotates, the two baffles 13 are driven to move relative to each other. Specifically, in this embodiment, each baffle 13 is fixedly connected with a slider 24 on both sides, and a slide groove 4 for the slider 24 to slide is provided on the base 1. The double-headed screw 93 passes through and is threadedly connected to a group of sliders 24 on the same side of the two baffles 13. For details, please refer to Figure 4 shown.

[0038] like Figure 1 As shown, in this embodiment, a controller 7 which is signal-connected to the motor 91 and the injection molding mechanism 6 is fixedly connected to the mounting frame 5 .

[0039] like Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, one end of the slider 24 away from the double-headed screw 93 extends to the top of the base 1 and is fixedly connected to the rack 16. The base 1 is rotatably connected to a driving gear 12 meshing with the rack 16 through a first rotating shaft 15. The base 1 is rotatably connected to a driven gear 14 meshing with the driving gear 12 through a second rotating shaft 17. A shifting rod 18 is fixedly connected to the second rotating shaft 17. Two supporting plates 21 are relatively fixedly connected to the forming cylinder 10. A knocking rod 19 that intermittently collides with the forming cylinder 10 is rotatably connected between the two supporting plates 21 through a third rotating shaft 22. The knocking rod 19 intermittently conflicts with the shifting rod 18. A torsion spring 23 is sleeved on the three rotating shafts 22, and the two ends of the torsion spring 23 are fixedly connected to the knocking rod 19 and the support plate 21 respectively. The rack 16 is extended along the sliding direction of the slider 24. The diameter of the driving gear 12 is larger than the diameter of the driven gear 14. The lever 18 is an L-shaped structure, and the end of the knocking rod 19 away from the lever 18 is fixedly connected with a knocking ball 20. Specifically, the cooperation of multiple sets of gears can increase the number of rotations of the lever 18, thereby increasing the number of times the molding tube 10 is knocked, which is convenient for the collection of silicone parts. At the same time, the setting of the torsion spring 23 can facilitate the resetting of the knocking rod 19, ensuring that the knocking rod 19 can contact the lever 18.

[0040] like Figure 1 , Figure 2 and Figure 8 As shown, in the present embodiment, a collecting groove 3 is further included, which is arranged at the bottom of the base 1, and the opening of the collecting groove 3 is arranged opposite to the through hole 11. A guide plate 8 inclined from high to low is fixedly connected in the collecting groove 3. Specifically, the setting of the guide plate 8 facilitates guiding the silicone parts discharged along the through hole 11 to be discharged into the collecting groove 3, further avoiding the damage of the silicone parts.

[0041] Working principle:

[0042] When it is necessary to take out the silicone piece in the forming tube 10, the motor 91 is started by the controller 7, and the motor 91 drives the double-headed screw 93 to rotate, so that the two baffles 13 move away from each other, so that the baffles 13 no longer block the through hole 11. At this time, the rack 16 on the slider 24 drives the active gear 12 to rotate, and the active gear 12 drives the driven gear 14 to rotate, and the driven gear 14 drives the lever 18 to rotate, and the lever 18 intermittently conflicts with the bottom of the knocking rod 19, so that the knocking rod 19 drives the knocking ball 20 to knock the forming tube 10. At the same time, under the action of the torsion spring 23, the knocking ball 20 and the knocking rod 19 can intermittently knock the molding tube 10, so that the silicone parts in the molding tube 10 can fall into the collecting tank 3. The overall operation is simple and the degree of automation is high, which ensures the collection of silicone parts and avoids damage to the silicone parts. It solves the problem that the motor 91 of the existing silicone injection molding device drives the mold to rotate to fit with the rubber support plate 21, and the product inside the mold is prone to fall off prematurely, thereby causing the product to not fall accurately into the receiving box.
