Description

Technical Field

[0001] This invention relates to the field of rubber product processing technology, specifically to a vertical rubber injection molding machine and its usage method. Background Technology

[0002] Rubber injection molding machines are specialized automated molding equipment for rubber and silicone raw materials. They feed fully mixed rubber materials into a heated barrel for plasticization, and then inject the rubber materials into a sealed mold cavity under high pressure through a screw or plunger. High-temperature vulcanization and curing are completed in the mold to finally obtain various rubber products. Compared with traditional compression molding processes, it can achieve high-precision and high-consistency automated continuous production, significantly shorten the production cycle, and is widely applicable to the large-scale processing needs of precision rubber products in many fields such as automotive seals, medical silicone parts, and electronic insulation accessories. Currently, in order to improve the performance of rubber products, a small amount of additives are added to rubber raw materials. However, in traditional rubber injection molding machines, due to the lack of effective mixing measures before the raw materials are melted, the additives are prone to uneven distribution, which leads to uneven hardness and local mechanical property degradation in the molded products.

[0026] like Figures 1-5 As shown, it illustrates a vertical rubber injection molding machine according to an embodiment of the present invention, comprising: The frame 1 has a support frame 2 fixedly connected to its top end, and an injection mechanism 3 fixedly connected to its top end. A molding die 4 is fixedly connected to one end of the frame 1 near the injection mechanism 3, and the nozzle of the injection mechanism 3 is connected to the injection port of the molding die 4.

The extension frame 5 is equipped with a pretreatment component 6, which is used to mix rubber raw materials and additives. Pretreatment component 6 is assembled between extension frame 5 and injection mechanism 3. Pretreatment component 6 is used to feed the mixed raw material into injection mechanism 3. More specifically, the injection mechanism 3 consists of a screw barrel with segmented heating, a check valve, a nozzle, a storage motor that drives the screw, an injection cylinder that controls the screw's advance and retreat, and an injection seat cylinder that moves the barrel. During operation, rubber granules enter from the barrel and are plasticized and melted by the shear heat from the screw rotation and the auxiliary heat from the external heater of the barrel. Then, the injection cylinder pushes the screw forward and injects the homogenized molten rubber into the cavity of the molding mold 4 through the nozzle at a set pressure and speed. At the same time, the check valve can prevent the molten rubber from flowing back during injection, thereby accurately controlling the injection volume and ensuring the molding accuracy of the product. This is a mature existing technology and will not be described in detail here. Furthermore, the molding die 4 consists of a molding cavity composed of a moving die and a fixed die, as well as a gating runner, a temperature-controlled cooling circuit, a guiding and positioning mechanism, and an ejection mechanism. After the mold is closed, the moving and fixed dies are precisely closed to form a sealed cavity. The molten rubber material is injected into the cavity through the injection mechanism 3, and is cooled and solidified by temperature control through the temperature-controlled circuit. After the mold is opened, the ejection mechanism ejects the molded product from the cavity, completing a single molding process. This is a mature existing technology and will not be described in detail here.

The top of the pretreatment box 8 is fixedly connected to the transmission box 9. The middle of the transmission box 9 is vertically rotatably connected to the mixing shaft A10. Please refer to Figure 4 In this embodiment, a raw material adding pipe and an additive injection pipe are fixedly connected to the pretreatment box 8 so that the rubber raw material and additives can smoothly enter the pretreatment box 8 and be concentrated inside. Hollow shaft 11 is fixedly connected to the bottom end inside the transmission box 9. A support plate 12 is rotatably connected to the hollow shaft 11. A hybrid shaft B13 is rotatably connected to one end of the support plate 12. Please refer to Figure 6 In this embodiment, the bottom end of the transmission box 9 is provided with an avoidance groove, the avoidance groove is arc-shaped, and the hybrid shaft B13 is located inside the avoidance groove; More specifically, by setting up the clearance slot, the mixing shaft B13 can pass through the transmission box 9 and enter the interior of the pretreatment box 8, and can provide space for the swing of the mixing shaft B13, so as to avoid the presence of the transmission box 9 from affecting the adjustment of the mixing shaft B13. Please refer to Figure 6 In this embodiment, multiple mixing blades are fixedly connected to the outer sides of mixing shaft A10 and mixing shaft B13. By setting the mixing blades, the contact range between mixing shaft A10 and mixing shaft B13 and the material in pretreatment box 8 can be effectively provided, ensuring the application effect of mixing shaft A10 and mixing shaft B13. Transmission assembly 14 is mounted on the top of transmission box 9. Transmission assembly 14 is used to provide power for the rotation of hybrid shaft A10 and the oscillation of hybrid shaft B13.

Please refer to Figure 7 In this embodiment, the feeding component 7 includes: Feeding pipe 24 is fixedly connected to the bottom of pretreatment box 8, and the end of feeding pipe 24 away from pretreatment box 8 is also connected to the inlet of injection mechanism 3.

Please refer to Figure 7 In this embodiment, the bottom end of the pretreatment box 8 is provided with an inclined surface that is inclined towards the injection mechanism 3, and the feeding pipe 24 is fixedly connected to the bottom end of the inclined surface. More specifically, by setting the inclined plane, the raw material at the bottom of the pretreatment box 8 can be transferred to the direction of the feeding pipe 24, so that the raw material in the pretreatment box 8 can be discharged more thoroughly. Please refer to Figure 7 In this embodiment, the bottom end of the feeding pipe 24 is bent toward the injection mechanism 3. By setting the feeding pipe 24, the raw material entering the feeding pipe 24 can be sent to the injection mechanism 3 by means of the inclination of the feeding pipe 24. The support frame 28 is fixedly connected to one side of the extension frame 5. One end of the support frame 28 is rotatably connected to the support shaft 29 and the drive shaft 30. One end of the support shaft 29 is fixedly connected to the striking plate 31. The striking plate 31 has a force-bearing through groove 32 in the middle. Please refer to Figure 8 In this embodiment, the end of the striking plate 31 away from the support shaft 29 is arc-shaped, and a protective pad is fixedly connected to the bottom end of the feeding tube 24. More specifically, by utilizing the shape characteristics of the end of the striking plate 31 away from the support shaft 29, the striking plate 31 can smoothly contact the bottom end of the feeding tube 24, thus avoiding motion interference between the striking plate 31 and the feeding tube 24. Furthermore, the protective pad can prevent damage to the feed tube 24 caused by prolonged impact. Eccentric plate B33 is fixedly connected to one end of drive shaft 30. The end of eccentric plate B33 away from drive shaft 30 is fixedly connected to transmission pipe 34, and transmission pipe 34 is also movably connected inside force-receiving groove 32. The upright plate 35 is fixedly connected to the top of the support frame 28. An electric push rod 36 is fixedly connected to one side of the upright plate 35. A push plate 37 is fixedly connected to the output end of the electric push rod 36. A push rod 38 is rotatably connected to the top of the push plate 37, and the end of the push rod 38 away from the push plate 37 is also rotatably connected to the eccentric plate A27. Please refer to Figure 8 In this embodiment, a guide rod is fixedly connected between one side of the upright plate 35 and the support frame 28, and the push plate 37 is also slidably connected to the guide rod; More specifically, the guide rods effectively guide the displacement of the push plate 37, preventing uncontrollable adjustments to the push plate 37 and greatly ensuring the stability of the push plate 37 during application. Please refer to Figure 8 In this embodiment, the top of the push plate 37 and the end of the eccentric plate A27 away from the sealing plate 26 are both provided with a rotating shaft, and the two ends of the push rod 38 are respectively connected to the two rotating shafts. More specifically, by setting the pivot, the end of the push rod 38 can be effectively assembled, ensuring the linkage effect between the push rod 38 and the push plate 37 and the eccentric plate A27; The displacement rod 39 is rotatably connected to one end of the push plate 37, and one end of the displacement rod 39 is also inserted into the inside of the drive shaft 30. The other end of the displacement rod 39 is fixedly connected to the matching bevel gear 40. The bottom end of the mixing shaft A10 is fixedly connected to the transmission bevel gear 41, and the transmission bevel gear 41 is also meshed with the matching bevel gear 40. Please refer to Figure 8 In this embodiment, a insertion hole is provided at one end of the drive shaft 30 near the displacement rod 39, a limit groove is provided on the inner wall of the insertion hole, a limit strip is fixedly connected to the outer side of the displacement rod 39, and the limit strip is also slidably connected inside the limit groove. More specifically, the design of the insertion hole allows the drive shaft 30 to accommodate the displacement rod 39, enabling the displacement rod 39 to be adaptively adjusted within the insertion hole. Furthermore, the structure of the limiting strip and the limiting groove provides guidance for the displacement of the displacement rod 39. When the displacement rod 39 rotates, the limiting strip can drive the drive shaft 30 to rotate synchronously. In use, the rubber raw materials and additives are first introduced into the pretreatment box 8 for concentration. Then, the drive motor 16 is started, and the power of the drive motor 16 is transmitted to the mixing shaft A10 through the reducer 15, causing the mixing shaft A10 to rotate. With the connection of the two drive spur gears 21, the power of the mixing shaft A10 can be transmitted to the guide shaft 17, causing the guide shaft 17 to drive the guide plate 18 to rotate. Since the guide rod 19 is connected inside the guide channel 20, when the guide plate 18 rotates with the guide shaft 17, the adaptive movement of the guide rod 19 inside the guide channel 20 can drive the support plate 12 to swing back and forth, thereby changing the position of the mixing shaft B13. During the adjustment of the mixing shaft B13, the linkage spur gear 23 will move along the positioning gear ring 22, thereby causing the mixing shaft B13 to rotate adaptively. In this way, the mixing shaft A10 and the mixing shaft B13 form a mixture between the rubber raw materials and the additives. After mixing, the electric push rod 36 is activated to pull the push plate 37 to move, causing the displacement rod 39 to gradually move out of the drive shaft rod 30 until the drive bevel gear 40 meshes with the transmission bevel gear 41. Since the displacement rod 39 is connected between the push plate 37 and the eccentric plate A27, during the displacement of the push plate 37, the eccentric plate A27 can be pulled by the push rod 38, thereby driving the sealing plate 26 to rotate, releasing the blockage of the feeding pipe 24. Then, the raw material in the pretreatment box 8 can fall into the feeding pipe 24 under the action of gravity and be sent to the injection mechanism 3 along the feeding pipe 24. When feeding material to the injection mechanism 3, the drive motor 16 is started, causing the mixing shaft A10 to rotate. At the same time, the mixing shaft B13 is driven to swing back and forth above the feeding pipe 24. With the connection between the drive bevel gear 40 and the transmission bevel gear 41, when the mixing shaft A10 rotates, the drive bevel gear 40 can be driven by the transmission bevel gear 41 to drive the drive shaft 30 to rotate through the displacement rod 39. Since the transmission pipe 34 is connected inside the force-bearing groove 32, as the eccentric plate B33 rotates with the drive shaft 30, it can drive the striking plate 31 to swing back and forth under the support of the support shaft 29. When the striking plate 31 swings to the highest point, it will strike the feeding pipe 24, causing the feeding pipe 24 to vibrate slightly, thereby preventing the raw material from being blocked at the feeding pipe 24.

[0027] On the other hand, the present invention also provides a method for using a vertical rubber injection molding machine, the steps of which are as follows: The first step is to introduce the rubber raw materials and their additives into the pretreatment box 8 for centralized processing; The second step is to provide rotational power to the mixing shaft A10 and oscillating power to the mixing shaft B13 through the transmission assembly 14, so as to mix the rubber raw materials and additives by means of the mixing shaft A10 and the mixing shaft B13; The third step is to feed the raw materials inside the pretreatment box 8 into the injection mechanism 3 through the feeding assembly 7, and after being processed by the injection mechanism 3, send them into the molding mold 4. The fourth step is to mold the rubber product using molding die 4.

[0028] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
