Technical Field

[0001] This utility model relates to the field of injection molds, specifically to an injection mold with a guiding material ejection function. Background Technology

[0002] Injection molds heat and inject plastic material into the mold cavity, which then cools and solidifies to form a product. The principle is to use high pressure to inject molten plastic material into the mold cavity, and then remove the molded product after cooling. Injection molds are widely used in various fields. Large injection molds refer to molds used to produce large plastic products, which usually have large size and complex structure.

[0003] Existing large injection molds, due to their large size and space occupation during the injection molding process, make it inconvenient to remove the molded parts, which leads to a decrease in the production efficiency of large injection molded parts.

[0025] like Figures 1-5 ;

[0026] An injection mold with a guiding ejection function includes a lower mold base 1. An ejection mechanism 2 is provided on the outer side of the lower mold base 1 to facilitate the guiding ejection of the injection molded part inside the injection mold. The ejection mechanism 2 includes a support component 23 and an ejection component 24. The support component 23 is located above the lower mold base 1 and is used to support the injection molded part to be removed from the lower mold base 1. The ejection component 24 is located on one side of the lower mold base 1 and is used to guide the injection molded part on the support component 23 to be ejected. The injection molded part is supported by a material support frame to detach from the lower mold base. By changing the position of the material support frame and by pushing the injection molded part on the material support frame to the placement platform through a push plate, it is not only convenient to guide and pick up large injection molded parts, but also to automate the material picking process, making it more convenient and faster, and improving the efficiency of the injection molding process.

[0027] Furthermore, a first bracket 21 is provided on one side of the lower mold base 1, and a second bracket 212 is provided on the other side of the lower mold base 1. The first bracket 21 and the second bracket 212 are used to support and install the guide rail 211. The guide rail 211 is fixedly installed between the top of the first bracket 21 and the second bracket 212. The guide rail 211 is periodically lubricated with oil. The guide rail 211 is used to support the movement of the first support plate 231. An electrical box is also provided on the second bracket 212, which is electrically connected to the first hydraulic cylinder 22, the second hydraulic cylinder 233 and the third hydraulic cylinder 243 respectively.

[0028] Furthermore, the support assembly 23 includes a first support plate 231 and a guide plate 232. The first support plate 231 is slidably mounted on the guide rail 211 and is used to support and install the second hydraulic cylinder 233. The position of the upper mold base 234 can be changed by sliding the first support plate 231. Guide plates 232 are installed on both sides of the top of the first support plate 231. The guide plates 232 are used not only to connect the second hydraulic cylinder 233 but also to guide the movement of the first support plate 231. The second hydraulic cylinder 233 is installed on the top of the first support plate 231. Two hydraulic cylinders 233 are used to support the lifting and lowering of the upper mold base 234. The output end of the second hydraulic cylinder 233 is connected to the upper mold base 234. The upper mold base 234 and the lower mold base 1 are used together. The top of the upper mold base 234 is also provided with an injection port. The bottom of the upper mold base 234 is equipped with a material support frame 235. The surface of the material support frame 235 is smooth. The material support frame 235 is used to support the injection molded part to be taken out from the lower mold base 1. A first hydraulic cylinder 22 is installed on one side of the first bracket 21. The output end of the first hydraulic cylinder 22 is connected to the guide plate 232. The first hydraulic cylinder 22 is used to push and pull the first hydraulic cylinder 22.

[0029] Furthermore, the unloading assembly 24 includes a base 241 and a placement platform 245. The base 241 is disposed between the lower mold base 1 and the second bracket 212. The base 241 is used to support and install the placement platform 245 and the second support plate 242. One end of the base 241 is configured as the placement platform 245. The injection molded part is moved from the material carrier 235 and placed on the placement platform 245. The top of the placement platform 245 is higher than the base 241. The second support plate 242 is fixedly installed at one end of the base 241. The descent height of the first support plate 231 is limited by the second support plate 242. At this position, the bottom of the injection molded part and the top of the material placement platform 245 are on the same horizontal plane. A third hydraulic cylinder 243 is installed on the second support plate 242. The third hydraulic cylinder 243 is used to push the push plate 244. The output end of the third hydraulic cylinder 243 is equipped with the push plate 244. The injection molded part on the material support frame 235 is pushed onto the material placement platform 245 through the push plate 244. A slot 25 is opened inside the lower mold base 1. The slot 25 is used to fit and insert the material support frame 235. After the upper mold base 234 is inserted into the top of the lower mold base 1, the material support frame 235 is matched and inserted into the slot 25.

[0030] The working principle of this utility model is as follows: A second hydraulic cylinder 233 is installed on the top of the first support plate 231. The output end of the second hydraulic cylinder 233 is connected to the upper mold base 234. When the first support plate 231 is positioned close to the first hydraulic cylinder 22, the upper mold base 234 is directly above the lower mold base 1. The second hydraulic cylinder 233 supports the upper mold base 234 and inserts it into the top of the lower mold base 1. The material support frame 235 fits into the slot 25. Molding liquid is injected through the injection port on the top of the upper mold base 234. When the molding liquid needs to be demolded, the second hydraulic cylinder 233 supports the upper mold base 234 to lift. The material support frame 235 supports the molded part to detach from the lower mold base 1. Then, the first hydraulic cylinder 22 pushes against the first hydraulic cylinder 22. Guide plates 232 are installed on both sides of the top of the first support plate 231. The first hydraulic cylinder 22 is guided by the guide plate 232 on the guide rail 211 to move to the far end of the other end. The second hydraulic cylinder 233 then supports the upper mold base 234 to descend. One end of the base 241 is set as the material placement platform 245. The other end of the base 241 is fixedly installed with the second support plate 242. The third hydraulic cylinder 243 is installed on the second support plate 242. The descent height of the first support plate 231 is limited by the second support plate 242. After the bottom of the first support plate 231 is attached to the top of the second support plate 242, the bottom of the material support frame 235 is also attached to the top of the base 241. At this time, the bottom of the injection molded part and the top of the material placement platform 245 are at the same level. The third hydraulic cylinder 243 pushes the push plate 244, and the push plate 244 guides the injection molded part on the material support frame 235 to be pushed onto the material placement platform 245.

[0031] In summary, by setting a material ejection mechanism on the outside of a large injection mold, the injection molded part is supported by the material support frame 235 to detach from the lower mold base 1. By changing the position of the material support frame 235 and guiding the injection molded part on the material support frame 235 to the material placement platform 245 by the push plate 244, it is not only convenient to guide and pick up large injection molded parts, but also to automate the material picking process, making it more convenient and faster, and improving the efficiency of the injection molding process.
