Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an injection molding mold for producing a tire blowout emergency safety device. Background Art

[0002] The tire blowout emergency safety device can effectively prevent the wheel hub from contacting the ground at the moment of a tire blowout, so that the steering force and braking force of the vehicle can still be controlled, ensuring the safety of people and vehicles at the first time. It is the fourth generation of automobile passive safety protection device system after seat belts, ABS, and airbags. It can ensure that the vehicle can still travel a certain distance safely and controllably after the tire is severely or completely depressurized. The tire blowout emergency safety device is made of plastic and metal. The plastic tire blowout emergency safety device is produced by injection molds;

[0003] However, the existing injection molds still have many shortcomings. For example, when cooling after injection molding, the cooling channel does not surround the inside and outside of the cavity for cooling, so the cooling molding time is long, and the coolant will carry some impurities when flowing in the circulation pipe for a long time. These impurities may block the circulation pipe, causing the coolant flow rate to weaken and the cooling effect to decrease. Utility Model Content

[0024] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0025] An injection molding mold for producing a tire blowout emergency safety device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a lower fixed plate 1, a mold foot 2, an ejector plate 3, a male module 4, and a female module 5. The upper end surface of the lower fixed plate 1 is respectively provided with two groups of mold feet 2 and ejector plates 3. The upper ends of the two groups of ejector plates 3 are connected to the male module 4 through guide columns 11. The guide columns 11 are fixedly connected to the upper ends of the mold feet 2 through fixed heads 10. Four groups of spring rods 12 are provided at the upper ends of the two groups of ejector plates 3. The upper end of the male module 4 is provided with a male mold cavity 9. The male module 4 and the female module 5 are connected by The guide column 11 is slidably connected to the guide sleeve 13, the female module 5 is fixedly connected to the fixing rod 7 through the male mold cavity 9, the upper end of the fixing rod 7 is provided with a positioning ring 8, and two groups of mounting plates 14 are symmetrically connected to the two sides of the male module 4, and the inner wall of each group of mounting plates 14 is plugged with two groups of infusion connectors 15, each group of mounting plates 14 is connected to the outer cooling pipe 18 and the inner cooling pipe 19, each group of infusion connectors 15 is connected to the infusion pipe 17, and the outer wall of each group of infusion pipe 17 is provided with a sealing gasket 16;

[0026] The working principle of Example 1 is that after the injection mold is installed on the injection molding machine, the injection molding machine seals the male mold cavity 9 through the male module 4 and the female module 5, and the injection tube injects the male mold cavity 9 through the positioning ring 8, and then the coolant tube is connected to the infusion pipe 17, and the coolant tube is sealed by the sealing gasket 16, so as to avoid leakage when the coolant is input. The coolant flows into the outer cooling pipe 18 and the inner cooling pipe 19 through the infusion connector 15 and the mounting plate 14. The outer cooling pipe 18 and the inner cooling pipe 19 are respectively located on the inner and outer sides of the internal chamber of the male mold cavity 9. When the male mold cavity 9 is injected After completion, the outer cooling tube 18 and the inner cooling tube 19 cool and mold the injection molded tire blowout emergency safety device, and then the female module 5 slides on the outer wall of the guide column 11 through the guide sleeve 13 to separate the male module 4 from the female module 5, and the tire blowout emergency safety device injection molded in the male mold cavity 9 is removed, and then the male module 4 and the female module 5 are molded again. When the mold is molded too many times, fatigue deformation of the mold parts will occur, resulting in the scrapping of the mold. The spring rod 12 can play a buffering role when the mold is closed, reducing the wear of the mold parts, thereby extending the life of the mold. Example 2

[0027] Embodiment 2 is based on embodiment 1, further as Figure 3 and Figure 4 As shown, the outer wall of each mounting plate 14 is provided with four sets of spring switches 20, and each set of infusion connectors 15 is plugged into the inner wall of the mounting plate 14 through a mounting sleeve 21. The outer wall of each mounting sleeve 21 is provided with a rubber ring 22, and the interior of the mounting sleeve 21 is provided with a filter screen 23, which is connected to the inner side of the infusion connector 15;

[0028] The working principle of Example 2 is that after the coolant delivery pipe is connected to the infusion pipe 17, the coolant is fed into the infusion connector 15 through the infusion pipe 17, and the coolant flows through the filter 23, and then enters the outer cooling pipe 18 and the inner cooling pipe 19 through the diversion holes, so that the tire burst emergency safety device in the male mold cavity 9 can be cooled, and the impurities contained in the outer cooling pipe 18 and the inner cooling pipe 19 that have been circulating for a long time can be filtered out, so as to avoid the impurities blocking the outer cooling pipe 18 and the inner cooling pipe 19, resulting in a decrease in flow rate and a decrease in cooling effect. In a weak situation, when it is necessary to clean the filter screen 23, the retaining spring switches 20 on the upper and lower sides of the mounting plate 14 are pressed simultaneously to retract the fixed retaining spring in the mounting plate 14, and after the infusion connector 15 is pulled out from the inner wall of the mounting plate 14, the filter screen 23 is cleaned. After the filter screen 23 is cleaned, the infusion connector 15 is inserted into the inner wall of the mounting plate 14 through the mounting sleeve 21, and the retaining spring in the mounting plate 14 will fix the mounting sleeve 21. The outer wall of the mounting sleeve 21 is provided with a plurality of rubber rings 22 for ensuring the airtightness when the infusion connector 15 is connected to the mounting plate 14.
