Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a silicone rubber ring injection molding machine that facilitates material feeding. Background Technology

[0002] Silicone rubber rings are sealing rings made of silicone rubber. Due to their excellent heat resistance, low-temperature elasticity, and resistance to oxidation and ozone, silicone rubber rings are widely used in waterproof structural components of electronic products, the automotive industry, and medical devices. Silicone rubber rings are manufactured using injection molding. The main raw material for silicone rubber rings is silicone rubber. The working principle of an injection molding machine is to heat and melt plastic granules, then inject them into a closed mold cavity under high pressure, where they cool and solidify to form the final product. Its workflow includes a cyclical process of mold closing, injection, pressure holding, cooling, mold opening, and ejection of the finished product.

[0003] Injection molding machines are relatively large, and the feeding port is usually located on top of the machine. During the feeding process, workers need to climb up to the top of the injection molding machine to perform the feeding operation. Since a large amount of raw material needs to be added to the feeding port of the injection molding machine at one time, and the weight of the raw material is large, the workers expend a lot of physical strength during the feeding process, and it is not convenient to automatically feed, thus affecting the production efficiency of silicone rubber rings. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a silicone rubber ring injection molding machine that facilitates feeding, solving the technical problems of existing injection molding machines relying on manual feeding, which results in slow feeding speed, high consumption of human resources, and reduced production efficiency of silicone rubber rings due to manual feeding.

[0005] According to one aspect, at least one embodiment of the present invention provides a silicone rubber ring injection molding machine that facilitates feeding, including an injection molding machine body, a feeding pipe fixedly connected to the top end of the injection molding machine body, a feeding hopper fixedly connected to the top end of the feeding pipe, and a feeding assembly provided between the injection molding machine body and the feeding hopper.

[0006] The feeding assembly includes a material box fixedly connected to the outside of the injection molding machine body. The inside of the material box is provided with a material trough. A longitudinal feeding pipe is fixedly connected to the side wall of the material trough. A longitudinal connecting shaft is rotatably connected inside the longitudinal feeding pipe. A longitudinal feeding auger is fixedly connected to the outer end of the longitudinal connecting shaft.

[0007] The feeding assembly also includes a connecting pipe fixedly connected to the top end of the longitudinal feeding pipe, a transverse feeding pipe fixedly connected and communicating with the feeding hopper, a transverse connecting shaft rotatably connected inside the transverse feeding pipe, and a transverse feeding auger fixedly connected to the outer end of the transverse connecting shaft.

[0008] For example, the cross-section of the material box is a right trapezoid, the bottom end of the material box is fixedly connected to a mounting plate, the outer end of the mounting plate is fixedly connected to a first servo motor, and the output end of the first servo motor is fixedly connected to a transmission bevel gear.

[0009] For example, the longitudinal connecting shaft is rotatably connected to the mounting plate, and a driven bevel gear is fixedly connected to the outer end of the longitudinal connecting shaft. The transmission bevel gear meshes with the driven bevel gear, and both the transmission bevel gear and the driven bevel gear are located inside the mounting plate.

[0010] For example, a second servo motor is fixedly connected to the outer end of the connecting pipe, the output end of the second servo motor is fixedly connected to the transverse connecting shaft, and a storage hopper is fixedly connected to the top end of the connecting pipe and is in communication with it.

[0011] For example, a sealing cover is fixedly connected to the top of the feed hopper, a third servo motor is fixedly connected to the top of the sealing cover, and a stirring belt is fixedly connected to the output end of the third servo motor. The stirring belt is rotatably connected to the inside of the feed hopper.

[0012] For example, the top of the material box has a cavity, and a material discharge plate is fixedly connected inside the cavity. The top of the material discharge plate has a concave hole, and the side wall of the material box has a discharge hole, which is connected to the cavity.

[0013] For example, a control motor is fixedly connected to the outer end of the material box, and a lead screw is fixedly connected to the output end of the control motor. The lead screw is rotatably connected to the cavity inside the material box.

[0014] For example, the outer end of the lead screw is threadedly connected to a slider, which is slidably connected to the inside of the blanking plate, and a cutter is fixedly connected to the top of the slider.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] In this invention, a longitudinal feeding auger rotating inside the longitudinal feeding pipe drives the raw material inside the hopper to be lifted and transported to the inside of the connecting pipe. At the same time, a transverse feeding auger rotating inside the transverse feeding pipe drives the raw material inside the connecting pipe to move inside the transverse feeding pipe and enter the inside of the feeding hopper.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-4 As shown, it illustrates a silicone rubber ring injection molding machine with easy feeding in one embodiment of the present invention, including an injection molding machine body 1, a feeding pipe 2 fixedly connected to the top of the injection molding machine body 1, a feeding hopper 3 fixedly connected to the top of the feeding pipe 2, and a feeding assembly 4 provided between the injection molding machine body 1 and the feeding hopper 3.

[0031] The feeding assembly 4 includes a material box 401 fixedly connected to the outside of the injection molding machine body 1. The inside of the material box 401 is provided with a material trough. A longitudinal feeding pipe 402 is fixedly connected to the side wall of the material trough. A longitudinal connecting shaft 403 is rotatably connected inside the longitudinal feeding pipe 402. A longitudinal feeding auger 404 is fixedly connected to the outer end of the longitudinal connecting shaft 403.

[0032] The feeding assembly 4 also includes a connecting pipe 405 fixedly connected to the top end of the longitudinal feeding pipe 402, a transverse feeding pipe 406 fixedly connected and communicating with the feeding hopper 3, a transverse connecting shaft 407 rotatably connected inside the transverse feeding pipe 406, and a transverse feeding auger 408 fixedly connected to the outer end of the transverse connecting shaft 407.

[0033] In some examples, the raw material is poured into the inside of the hopper 401. During the feeding process, the longitudinal connecting shaft 403 drives the longitudinal feeding auger 404 at its outer end and the transverse connecting shaft 407 drives the transverse feeding auger 408 at its outer end to rotate inside the longitudinal feeding pipe 402 and the transverse feeding pipe 406, respectively. This allows the raw material in the hopper 401 to be transported to the inside of the feed hopper 3. This feeding method is convenient and simple, and can automatically feed and replenish the inside of the feed hopper 3 without requiring workers to climb to feed the material. It saves labor and makes the feeding operation of the feed hopper 3 simpler. The longitudinal feeding auger 404 and the transverse feeding auger 408 feed the inside of the feed hopper 3 in a timely manner, avoiding the normal injection operation of the injection molding machine body 1 from being affected by timely replenishment of material.

[0034] For example, such as Figures 2-3 As shown, the cross-section of the material box 401 is a right trapezoid. The bottom end of the material box 401 is fixedly connected to the mounting plate 5. The outer end of the mounting plate 5 is fixedly connected to the first servo motor 6. The output end of the first servo motor 6 is fixedly connected to the transmission bevel gear 7.

[0035] The longitudinal connecting shaft 403 is rotatably connected to the mounting plate 5. The outer end of the longitudinal connecting shaft 403 is fixedly connected to the driven bevel gear 8. The transmission bevel gear 7 meshes with the driven bevel gear 8. Both the transmission bevel gear 7 and the driven bevel gear 8 are located inside the mounting plate 5.

[0036] In some examples, during the feeding process, the first servo motor 6 drives the transmission bevel gear 7 to rotate inside the mounting plate 5. The rotating transmission bevel gear 7 drives the driven bevel gear 8 to rotate the longitudinal connecting shaft 403, thereby causing the longitudinal feeding auger 404 to rotate inside the longitudinal feeding pipe 402, thereby causing the raw material inside the hopper 401 to be lifted inside the longitudinal feeding pipe 402.

[0037] For example, such as Figure 1 As shown, a second servo motor 9 is fixedly connected to the outer end of the connecting pipe 405. The output end of the second servo motor 9 is fixedly connected to the transverse connecting shaft 407. A storage hopper 10 is fixedly connected to the top end of the connecting pipe 405 and they are in communication.

[0038] In some examples, during the lifting process of the raw material, the second servo motor 9 drives the transverse connecting shaft 407 to drive the transverse feeding auger 408 at its outer end to rotate, so that the raw material inside the connecting pipe 405 is transported from the transverse feeding pipe 406 to the inside of the feeding hopper 3. During the lifting process, some of the material enters the inside of the storage hopper 10 for storage. When the raw material inside the material box 401 is insufficient, the raw material inside the storage hopper 10 automatically falls into the inside of the connecting pipe 405 under gravity. At this time, the transverse feeding auger 408 drives the raw material inside the connecting pipe 405 into the inside of the feeding hopper 3.

[0039] like Figures 1-2 As shown, this invention illustrates a silicone rubber ring injection molding machine with easy feeding in another embodiment of the present invention. A sealing cover 11 is fixedly connected to the top of the feeding hopper 3, and a third servo motor 12 is fixedly connected to the top of the sealing cover 11. A stirring belt 13 is fixedly connected to the output end of the third servo motor 12, and the stirring belt 13 is rotatably connected to the inside of the feeding hopper 3.

[0040] In some examples, when there is a lot of raw material inside the feed hopper 3, blockage may occur. At this time, the third servo motor 12 drives the stirring belt 13 at its output end to rotate, stirring the raw material inside the feed hopper 3, thereby preventing blockage. At the same time, the top of the sealing cover 11 is provided with a cover plate, which makes it easy to open the cover plate and thus facilitates cleaning of the inside of the feed hopper 3.

[0041] For example, such as Figures 4-5 As shown, the top of the material box 401 has a cavity, and a material drop plate 14 is fixedly connected inside the cavity. The top of the material drop plate 14 has a concave hole, and the side wall of the material box 401 has a discharge hole 15, which is connected to the cavity.

[0042] A control motor 16 is fixedly connected to the outer end of the material box 401, and a lead screw 17 is fixedly connected to the output end of the control motor 16. The lead screw 17 is rotatably connected to the cavity inside the material box 401.

[0043] The outer end of the lead screw 17 is threaded with a slider, which is slidably connected to the inside of the blanking plate 14, and the top of the slider is fixedly connected with a cutter 18.

[0044] In some examples, the raw materials are usually in bagged form. Before loading, the staff needs to open the packaging bags, which causes great inconvenience to the staff. During the loading process, the bagged raw materials are placed into the groove at the top of the material box 401. At this time, the control motor 16 drives the lead screw 17 to rotate inside the material box 401. The rotating lead screw 17 drives the slider and the cutter 18 at its top to move back and forth at the top of the discharge plate 14. The front end of the cutter 18 is pointed. At this time, the moving cutter 18 can cut the packaging bag. At this time, the raw materials fall from the packaging bag to the top of the discharge plate 14. At the same time, the raw materials fall into the cavity of the material box 401 from the concave hole at the top of the discharge plate 14. The side wall of the cavity inside the material box 401 is inclined. At this time, the raw materials fall into the interior of the material box 401 from the discharge hole 15 on the outside of the cavity. During the loading process, the staff does not need to manually unpack the bags, making the loading process much simpler.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
