Description

Technical Field

[0001] The invention relates to the technical field of injection moulds, in particular to a mould for a ready-to-mix liquid solute beverage bottle cap which is easy to demould. Background Art

[0002] Common beverages on the market are already mixed with flavoring materials and water, but the shelf life of such beverages is very short, and most of them need to be drunk immediately after opening the lid; and in order to extend the shelf life, a lot of additives need to be added, which is not good for human health. In order to solve these problems, there are now some beverages on the market that separate water and flavoring agents (i.e. solutes) and mix them when they need to be drunk, that is, ready-to-drink beverages.

[0003] For example, a demoulding device for a bottle cap mold with announcement number CN221985711U is provided with a bottom mold, a lateral moving mechanism and a mobile demoulding mechanism, so that after the bottle cap body and the bottom mold are demoulded, the bottom mold can be driven to slide inside the fixed support plate and be misaligned with the top mold by controlling the lateral moving mechanism, and then the bottom mold will drive the mobile demoulding mechanism to move synchronously laterally during the movement process, which is beneficial to utilize the fitting friction with the bottle cap body during the movement process to rotate the bottle cap body out of the forming mold to complete the demoulding of the bottle cap body. , which improves the demoulding efficiency of the demoulding device of the bottle cap mold. However, in actual use, when the bottle caps are batch injection molded, the top mold is lifted after the bottle caps are formed, and then the demoulding mechanism is driven to move by the servo motor so that the demoulding mechanism demoulds the bottle caps. After the bottle caps are demoulded, the servo motor needs to be controlled to reverse so that the demoulding mechanism is reset. When the bottle caps are demoulded, there are many demoulding steps and it takes a certain amount of time, which will increase the processing time of the bottle caps and reduce the working efficiency of the bottle cap processing. There are certain usage defects.

[0004] Therefore we have proposed a kind of mould for instant liquid solute beverage bottle cap that is easy to demould, so as to solve the above-mentioned problem. Summary of the invention

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the mold for the ready-to-dispense liquid solute beverage bottle cap that is easy to demould is provided with a demoulding component above the base, so that after the bottle cap is injection-molded, the bottle cap can be automatically demoulded by raising the upper mold, thereby reducing the demoulding steps and time, speeding up the injection molding efficiency of the bottle cap, and improving the work efficiency and practicality;

[0026] 1. A demoulding assembly is arranged above the base. When the instant liquid solute beverage bottle cap is injection molded, the upper mold is driven down by the driving structure to close the mold with the lower mold, so that the molding mold is inserted into the molding cavity, and the hot melt raw material is injected through the injection hole. After waiting for cooling, due to the internal thread on the bottle cap, the bottle cap will be attached to the molding mold after the upper mold is raised. After the upper mold moves up, the top contacts with the two sets of counterweights. The upper mold continues to move up to drive the counterweights to move up, so that the mounting plate moves up, and then the driving gear is driven to rotate through the meshing of the driving gear and the rack. After the driving gear rotates, the driven gear is driven to rotate through the connection between the driving pulley and the connecting pulley. Then, the movable plate can be pushed to move through the meshing of the driven gear and the toothed plate. During the movement, the movable plate drives the positioning bar to slide inside the positioning groove for limiting. After the movable plate moves, it drives the two support rods to move, so that the support rods slide on the support frame, so that the support rods approach the upper mold, and the upper mold During the movement, the mounting frame is driven to move upward, and the ball bearings on the support rod can rotate on the connecting plate, and then the movement of the support rod can push the connecting plate to move, thereby making the moving rod move. During the movement of the rod, the limit block slides inside the limit groove for limiting, and drives the guide rod to slide on the mounting frame and stretch the tension spring, so that after the moving rod moves, the rubber strip can contact the bottle cap on the forming mold, and the bottle cap is driven to rotate by the movement of the rubber strip, so that the rotating internal thread of the bottle cap is separated from the forming mold for demoulding, and the two right moving rods are arranged at the front side of the two right forming molds, and the two left moving rods are arranged at the rear side of the two left forming molds, so that the two groups of moving rods are close to each other to perform demoulding operations on the two groups of bottle caps, and the demoulding assembly makes it possible to automatically demould the bottle cap by lifting the upper mold after the bottle cap is injection molded, thereby reducing the steps and time of demoulding, speeding up the injection molding efficiency of the bottle cap, and improving work efficiency and practicality;

[0027] 2. When the bottle cap is demoulded, the driven gear rotates. After the driven gear rotates, the rotating shaft can be driven to rotate through the connecting pulley on the other side and the driven pulley. After the rotating shaft rotates, the two cams are driven to rotate. After the cam rotates, the push rod can be pushed to move. After the push rod moves, the movable rod can be pushed to slide on the cylinder body, and the telescopic spring is compressed to push the piston to slide inside the cylinder body. At this time, the one-way valve inside the air inlet pipe is closed, and the one-way valve inside the air outlet pipe is opened, so that the cylinder gas is ejected through the air outlet pipe, so that the molding cavity can be blown to avoid residual injection debris inside the molding cavity. When the cam rotates, the movable rod is reset under the action of the telescopic spring. After the movable rod is reset, the piston is driven to reset. At this time, the one-way valve inside the air inlet pipe is opened, and the one-way valve inside the air outlet pipe is closed, so that the outside air can be sucked into the cylinder body, so that when the bottle cap is demoulded, the molding cavity can be blown and cleaned to avoid affecting the next injection molding of the bottle cap;

[0028] 3. The air outlet pipe is supported and limited by a fixed seat. After the upper mold moves downward, the moving rod can contact the L-shaped frame on one side. As the moving rod moves downward, the moving seat can be driven to move downward, so that the sliding rod can slide on the U-shaped frame, and the reset spring can be stretched, so that when the upper mold and the lower mold are closed, the fixed seat can move downward with the upper mold to avoid affecting the normal closing of the upper and lower molds. After the upper mold is raised, the fixed seat can be raised to facilitate the subsequent blowing of the molding cavity. BRIEF DESCRIPTION OF THE DRAWINGS

After waiting for cooling, the bottle cap will be attached to the molding die 104 after the upper mold 102 is raised due to the internal thread on the bottle cap. After the upper mold 102 moves up, the top contacts with the two sets of counterweights 204. The upper mold 102 continues to move up to drive the counterweights 204 to move up, so that the mounting plate 205 is moved upward, and then the driving gear 208 is driven to rotate by the meshing of the driving gear 208 and the rack 206. After the driving gear 208 rotates, the driven gear 210 is driven to rotate by the connection between the driving pulley 212 and the connecting pulley 211. Then, the movable plate 213 can be pushed to move by the meshing of the driven gear 210 and the toothed plate 214. During the movement, the movable plate 213 drives the positioning bar 216 to slide inside the positioning groove 217 for limiting. After the movable plate 213 moves, it drives the two support rods 218 to move. The support rod 218 slides on the support frame 219, so that the support rod 218 approaches the upper mold 102. The upper mold 102 drives the mounting frame 221 to move upward during the movement. The ball 220 on the support rod 218 can rotate on the connecting plate 225. Then, the movement of the support rod 218 can push the connecting plate 225 to move, thereby moving the moving rod 223. During the movement of the moving rod 223, the limit block 227 slides inside the limit groove 226 to limit the position, and drives the guide rod 229 to slide on the mounting frame 221. The stretching spring 230 is stretched so that the rubber strip 224 can contact the bottle cap on the forming mold 104 after the moving rod 223 moves, and the bottle cap is driven to rotate by the movement of the rubber strip 224, so that the internal thread of the bottle cap is disengaged from the forming mold 104 for demoulding, and the two right moving rods 223 are arranged at the front side of the two right forming molds 104, and the two left moving rods 223 are arranged at the rear side of the two left forming molds 104, so that the two groups of moving rods 223 are close to each other and the two groups of bottle caps can be demoulded;

[0056] When the bottle cap is demoulded, the driven gear 210 rotates. After the driven gear 210 rotates, it can drive the rotating shaft 232 to rotate through the other side connecting pulley 211 and the driven pulley 233. After the rotating shaft 232 rotates, it drives the two cams 235 to rotate. After the cam 235 rotates, it can push the push rod 238 to move. After the push rod 238 moves, it can push the movable rod 236 to slide on the cylinder 234, and compress the telescopic spring 239 to push the piston 237 to slide inside the cylinder 234. At this time, the one-way valve inside the air inlet pipe 240 is closed, and the one-way valve inside the air outlet pipe 241 is opened, so that the gas in the cylinder 234 is ejected through the air outlet pipe 241, so that the molding cavity 103 can be blown to avoid residual injection molding debris inside the molding cavity 103. When the cam 235 rotates, the movable rod 236 is reset under the action of the telescopic spring 239. After the movable rod 236 is reset, it drives the piston 237 to reset. At this time, the one-way valve inside the air inlet pipe 240 is opened, and the one-way valve inside the air outlet pipe 241 is closed, so that the outside air can be sucked into the cylinder 234, so that when the bottle cap is demoulded, the molding cavity 103 can be blown and cleaned to avoid affecting the next injection molding of the bottle cap. The air outlet pipe 241 is supported and limited by the fixing seat 245. After the upper mold 102 moves downward, the moving rod 223 can contact the L-shaped frame 248 on one side. As the moving rod 223 The downward movement can drive the movable seat 244 to move downward, so that the sliding rod 243 can slide on the U-shaped frame 242, and the reset spring 246 can be stretched, so that when the upper mold 102 and the lower mold 101 are closed, the fixed seat 245 can move downward together with the downward movement of the upper mold 102 to avoid affecting the normal closing of the upper mold 102 and the lower mold 101, and after the upper mold 102 is raised, the fixed seat 245 can be raised to facilitate the subsequent blowing of the molding cavity 103.
