Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, and more specifically, to a cooling device for processing plastic products. Background Art

[0002] Plastic is a polymer compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] In the production process of plastic products, the plastic raw materials are usually first heated to a molten state, and then the molten plastic is injected into a mold with a specific cavity. The molten plastic in the mold is then cooled to harden it to produce a plastic product. The prior art usually opens a wavy channel in the mold and conveys flowing coolant into the channel to cool the molten plastic by the coolant. However, the conventional wavy channel has a low heat exchange area, resulting in a relatively low cooling effect. If fins are added to the channel to increase the heat exchange area, scale is easily accumulated at the fins, interfering with the heat exchange operation and resulting in a decrease in the cooling effect.

[0026] The scraping assembly includes a round rod 7, a spring 8 and a scraper 9; two round rods 7 are connected to the cover plate 4; each round rod 7 is sleeved with a spring 8, one end of the spring 8 is fixedly connected to the corresponding round rod 7, and the other end of the spring 8 is connected to the cover plate 4, and the round rod 7 is set to an alloy material; all the round rods 7 are fixedly connected with a scraper 9, and the scraper 9 is located on the lower side of the cover plate 4; each partition 5 is in contact with the scraper 9; each fin 6 is in contact with the scraper 9, and the scale on the partition 5 and the fin 6 is scraped off by the scraper 9.

[0027] It also includes a connecting plate 10; all the round rods 7 are fixedly connected with the connecting plate 10.

[0028] It also includes auxiliary components; the scraper 9 is connected to the auxiliary components; the auxiliary components include an elastic telescopic rod 11, a connecting plate 12, a scraper block 13 and an electromagnet 14; a plurality of elastic telescopic rods 11 are fixedly connected to the scraper 9; eight connecting plates 12 are slidably connected to the scraper 9, and the connecting plates 12 are fixedly connected to the corresponding telescopic ends of the elastic telescopic rods 11; a plurality of scraper blocks 13 are welded to each connecting plate 12; and eight electromagnets 14 are fixedly connected to the mold 1.

[0029] It also includes a sealing component; the sealing component is connected to the cover plate 4; the sealing component includes a ring 15, a sealing ring 16 and a waste discharge unit; two rings 15 are fixedly connected to the cover plate 4, and the rings 15 are located on the outside of the corresponding round rod 7; two sealing rings 16 are fixedly connected to each ring 15, and the sealing ring 16 is in contact with the corresponding round rod 7. Through the cooperation of the two sealing rings 16, the outside of the round rod 7 is double-sealed, which is beneficial to improve the sealing effect; the ring 15 is connected to the waste discharge unit; a cavity 2 92 is formed between each upper and lower adjacent two sealing rings 16; the waste discharge unit is used to discharge the coolant in the cavity 2 92.

[0030] The waste discharge unit includes a pipe three 17 and a plug 18; a pipe three 17 is passed through each ring 15, and the pipe three 17 is connected to the corresponding cavity two 92, and the coolant remaining in the cavity two 92 is discharged through the pipe three 17; a plug 18 is inserted into each pipe three 17, and the plug 18 is set to a plastic material.

[0031] The round rod 7 is made of heat-insulating material.

[0032] First, the external coolant circulation system is manually connected to pipe 1 2 and pipe 2 3. During cooling, the external coolant circulation system delivers coolant to pipe 1 2, and the coolant enters cavity 1 91 through pipe 1 2, and then flows back to the coolant circulation system from pipe 2 3, thereby cooling the mold 1 and the partition 5, and then cooling the molten plastic in the mold cavity of the mold 1 located in the partition 5. At the same time, the heat exchange area is increased by the fin 6, thereby improving the cooling efficiency. When the cooling effect is reduced, it means that there is too much scale attached to the partition 5 and the fin 6. At this time, the external coolant circulation system extracts the coolant in the cavity 1 91, and then manually presses the connecting plate 10 downward to connect the connecting plate 10. The round rod 7 is driven to move downward and the spring 8 is compressed. The round rod 7 drives the scraper 9 to move downward, and the scale on the partition 5 and the fin 6 is scraped off by the scraper 9. Then the connection plate 10 is manually stopped from being pressed, so that the spring 8 rebounds and drives the scraper 9 to move back to its original position. Then the external coolant circulation system injects flowing coolant into the cavity 91. The coolant flushes the scale scraped off in the cavity 91, and then the scale is filtered out by the filtering mechanism in the external coolant circulation system. When in use, the heat exchange area is increased by the fin 6, thereby improving the cooling efficiency. When the cooling effect is reduced, the connection plate 10 is manually pressed to quickly scrape off the scale on the partition 5 and the fin 6 by the scraper 9, so as to continue to maintain efficient cooling.

[0033] When the round rod 7 drives the scraper 9 to move downward, the scraper 9 will also drive the parts thereon to move downward, so that the scraper block 13 contacts the mold 1. At this time, the electromagnet 14 attracts the connecting plate 2 12 through magnetic force, so that the connecting plate 2 12 moves backward and stretches the elastic telescopic rod 11. The connecting plate 2 12 drives the scraper block 13 to move backward, so that the scale attached to the bottom of the cavity 1 91 is scraped off by the scraper block 13, thereby further improving the cooling efficiency.

[0034] The two sealing rings 16 cooperate with each other to perform a double seal on the outside of the round rod 7. When the coolant penetrates through the lower sealing ring 16, it will be stored in the second cavity 92. The coolant in the second cavity 92 is intercepted by the upper sealing ring 16 to prevent the coolant from penetrating to the upper side of the cover plate 4. During regular maintenance, the plug 18 is manually opened, and then the suction hose is passed through the pipe three 17 and inserted into the second cavity 92 to extract the coolant stored in the second cavity 92. When in use, the two sealing rings 16 cooperate with each other to perform a double seal on the outside of the round rod 7, which greatly improves the sealing effect. At the same time, the coolant remaining in the second cavity 92 can be discharged through the pipe three 17.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
