Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle processing, in particular to a multi-cavity bottle embryo rapid cooling device. Background Art

[0002] Multi-cavity preforms are usually used in the processing of plastic bottles. Multi-cavity preform molds are tools used to produce plastic preforms with multiple cavities. During the production process, plastic particles will be heated and injected into the multi-cavity preform mold. Through high-pressure injection molding or blow molding technology, the plastic will fill each cavity in the mold to form multiple preforms, which will then be cooled and solidified by a cooling device.

[0003] After searching, the Chinese patent announcement number: CN208867466U discloses a multi-cavity mold device for processing bottle embryos, including a fixed mold base and a movable mold base located below the fixed mold base, the upper surface of the fixed mold base is fixedly provided with a groove body, the interior of the groove body is embedded with a drainage mechanism, the lower surface of the movable mold base is fixedly connected with a support plate body, and a ejection mechanism that can separate the formed bottle embryo from the mold is arranged between the support plate body and the movable mold base. At the injection port of the original preform mold, an automatic sealing structure is arranged. When the injection slot in the preform mold is filled, the injection molding machine stops injecting, so that the slurry in the injection slot will not overflow from the preform mold. In addition, an automatic ejecting mechanism is arranged at the bottom of the preform mold.

However, the mold in the application allows the preform to be naturally cooled after injection molding, which results in low cooling efficiency of the preform and uneven cooling of the preform, resulting in poor quality of the preform after molding.

[0031] Specifically, by starting the electric push rod 2 18, the connected moving plate 9 can be driven to move. When the moving plate 9 on this side moves, the template 2 14 can be driven to contact the template 1 10 and inject materials. At the same time, under the action of the positioning rod 13, the template 10 and the template 2 14 can be positioned when they are fitted. Then, by starting the water pump 5, the cooling water in the water tank 3 can be pumped out, and the pumped water can be sent to the water inlet pipe 7 through the water pump 5. Through the water inlet pipe 7, it can be sent to the water storage chamber 15 for storage.

The output ends of the two electric push rods 206 penetrate the moving plate 9 on one side and are fixedly connected to the push plate 208. A support seat 202 is fixedly connected to the middle of the inner bottom wall of the base 1. A groove 205 is provided on the front and rear walls of the support seat 202.

When the push plate 208 is extended, the cooled and formed preforms can be pushed down, so that multiple preforms can fall onto the transmission belt 204. Then, the servo motor 201 can drive the transmission roller 203 connected to the output end to rotate, and the transmission belt 204 can be driven to rotate under the joint action of the two transmission rollers 203 on the front and rear sides. When the transmission belt 204 rotates, the preforms falling on the transmission belt 204 can be driven to be transported, and when the transmission belt 204 is transmitted, it will contact with the rotating shaft 207 and drive the rotating shaft 207 to contact. Under the action of the rotating shaft 207, the wear caused by the friction between the transmission belt 204 and the edge of the groove 205 can be reduced, thereby ensuring the service life of the transmission belt 204, and further achieving the effect of facilitating the unloading and feeding of the formed preforms.

[0035] Specifically, by providing a water filling pipe 4, it is convenient for workers to add cooling water to the water tank 3, by providing a protective cover 12, the internal mechanism of the base 1 can be protected, and by providing a visible window 11 on the protective cover 12, the internal mechanism of the base 1 can be protected while facilitating external workers to observe the interior.

[0036] Working principle: In actual use, by starting the water pump 5, the cooling water in the water tank 3 can be pumped out and sent to the water storage chamber 15 through the water inlet pipe 7. The cooling water entering the water storage chamber 15 will enter multiple cooling chambers 16 at the same time. The cooling water can cool the injection-molded bottle embryos at the same time during the flow of the cooling water in the cooling chambers 16. The cooled water will flow into the return pipe 6 through the water outlet pipe 17, and flow back to the water tank 3 through the return pipe 6 for repeated cooling, thereby achieving the effect of quickly and evenly cooling the injection-molded bottle embryos. In addition, by starting the electric push rod 206, the push plate 208 connected to the output end can be driven to push out, so that the cooled and formed bottle preforms can be pushed down, so that multiple bottle preforms can fall on the transmission belt 204, and then the servo motor 201 can drive the transmission roller 203 connected to the output end to rotate, so that the transmission belt 204 can be driven to rotate under the joint action of the two transmission rollers 203, so that the bottle preforms falling on the transmission belt 204 are transported, thereby achieving the effect of facilitating the unloading and feeding of the formed bottle preforms.
