[0002] With the rapid development of the sports equipment industry, the demand for high-quality sports accessories is increasing. Sports equipment accessories such as handles, brackets, and connectors require injection molds for production. Traditional injection molds for these accessories typically employ a single cooling layout, where coolant enters the mold's cooling "zone" through cooling channels. However, this design often results in uneven cooling, with some areas being excessively hot while others are too cold, failing to achieve the desired cooling effect. This temperature imbalance leads to poor flow of molten plastic within the mold, incomplete molding, and consequently, product appearance defects and decreased physical properties, affecting the overall performance of the sports equipment accessories.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, this utility model provides a circulating rapid cooling type injection mold for sports equipment accessories, including a mold main frame 1, a molding system 8 and an intelligent temperature control detection system 6 disposed on the mold main frame 1.

The lower mold base 102 is provided with a rapid cooling system 4 and a cooling circulation system 7 acting on the molding system 8. The rapid cooling system 4 and the cooling circulation system 7 are respectively connected to the intelligent temperature control detection system 6.

[0025] In this embodiment, the main frame of the mold consists of an upper mold base 101 and a lower mold base 102. When the mold is closed, the two fit tightly together to form a molding cavity 801. The molding system 8 is located between the upper mold base 101 and the lower mold base 102, and includes the cavity 801 and the core 802. The mold cavity is responsible for forming the outer shape of the plastic part, while the core 802 forms the internal structure of the plastic part. The core 802 is equipped with pipes of a rapid cooling system 4, which are arranged in a spiral manner to enhance the cooling effect of the coolant on the plastic.

[0026] The intelligent temperature control and detection system 6 includes a temperature detection module 601 and a control processing module 602, enabling real-time monitoring of the mold temperature. The control processing module 602 adjusts the operation of the cooling and heating systems 3 according to temperature data commands to ensure the mold temperature meets the set production requirements.

[0027] The rapid cooling system 4 includes an air inlet 401, a cold air input interface 405 located on one side of the air inlet 401, and a first coolant input interface 402. The air inlet 401 is provided with a first circulating cooling pipe 404, a first coolant output pipe 406, and a cold air control valve. The cold air control valve is connected to a plurality of cold air nozzles 403. The first coolant input interface 402 is connected to the first circulating cooling pipe 404, the first circulating cooling pipe 404 is connected to the first coolant output pipe 406, and the cold air control valve is connected to the cold air input interface 405.

[0028] The rapid cooling system 4 in this embodiment includes components such as a cold air nozzle 403 and a cold air input interface 405. Cold air is sprayed out through a cold air control valve to accelerate the cooling speed of the mold. In addition to cold air, the rapid cooling system 4 is also combined with a first circulating cooling pipe 404 to circulate coolant through the mold core and coolant output pipe to quickly achieve heat transfer.

[0029] The cooling circulation system 7 includes a coolant delivery guide seat 705 and a second coolant input interface 701 located on one side of the coolant delivery guide seat 705.

[0031] This embodiment combines a rapid cooling system 4 and a cooling circulation system 7, allowing operators to easily adjust the mold temperature and cooling conditions via an intelligent temperature control system, adapting to various production conditions and material types. Simultaneously, the mold can rapidly reduce internal and external temperatures, improving molding cycle time and increasing output. Its precise temperature control detection system ensures stable mold temperature, guaranteeing the dimensional and shape accuracy of the plastic parts and reducing defects. Furthermore, through efficient temperature control and cooling strategies, mold cooling and heating can be precisely controlled, reducing energy consumption, achieving higher economic efficiency, and avoiding material waste and time loss.

[0032] Furthermore, the molding system 8 is located between the upper mold base 101 and the lower mold base 102. The molding system 8 includes a cavity 801 and a core 802. The first circulating cooling pipe 404 is arranged in a spiral manner inside the core 802. Each of the cold air nozzles 403 is linearly distributed along the axial direction of the core 802. The second circulating cooling pipe 703 is spirally arranged around the outside of the cavity 801.

[0033] The first circulating cooling pipe 404 is arranged in a spiral shape inside the core 802, so that the coolant is evenly distributed throughout the core 802, increasing the cooling efficiency; the second circulating cooling pipe 703 is also arranged in a spiral shape on the outside of the cavity 801, ensuring rapid molding and cooling of the plastic part.

[0034] During the injection molding process, after the molten plastic is injected into the mold, the coolant flows through the first circulation cooling pipe 404, quickly carrying away the heat from the plastic. The cold air emitted by the cold air nozzle 403 can further reduce the temperature of the mold surface, enhancing the cooling effect.

[0035] Furthermore, the upper mold base 101 is also provided with an injection runner 103, a preheating system 2 and a heating system 3 acting on the injection runner 103. The preheating system 2 and the heating system 3 are respectively connected to an intelligent temperature control and detection system 6. The intelligent temperature control and detection system 6 includes a temperature detection module 601, a control processing module 602 and a digital display screen connected to the control processing module 602. The temperature detection module 601 is connected to the control processing module 602, wherein the cold air control valve and the coolant control valve 702 are respectively connected to the control processing module 602.

[0036] The preheating system 2 heats the plastic material in the runner during injection molding to ensure good flowability upon injection into the mold and prevent poor filling due to excessively low temperatures. The heating system 3 primarily heats a portion of the mold during molding to maintain mold temperature and ensure smooth flow and filling of the plastic material throughout the molding process. The connection between the heating system 3 and the intelligent temperature control and detection system 6 ensures precise control during the heating process.

[0037] The temperature detection module 601 monitors the temperature in the mold and runner in real time and obtains data feedback. The control processing module 602 automatically adjusts the working status of the preheating system 2 and the heating system 3 according to the temperature data and the preset temperature target to maintain the set temperature. The digital display screen is used to display the current temperature and other relevant parameters, so that the operator can clearly understand the system status and make manual adjustments when necessary.

[0038] Both the cold air control valve and the coolant control valve 702 are connected to the control processing module 602, allowing the intelligent system to automatically adjust the flow rate of the coolant and the duration of the cold air according to the temperature data of the mold to achieve the best cooling effect. When the mold temperature is too high, the cooling valve will automatically open to ensure that the mold cools down in time.

[0039] Furthermore, the preheating system 2 includes a first mounting base and a preheating air input interface 201 located on one side of the first mounting base. The first mounting base is provided with a preheating air control valve 202 and a preheating pipe 203 connected to the preheating air input interface 201. The preheating pipe 203 is connected to the preheating air control valve 202, and the preheating air control valve 202 is connected to the control processing module 602. The preheating pipe 203 is arranged in a spiral manner at the upper end of the injection molding channel 103.

[0040] The preheating system 2 heats the plastic material in the runner during injection molding to ensure good flowability upon injection into the mold and prevent poor filling due to excessively low temperatures. The heating system 3 primarily heats a portion of the mold during molding to maintain mold temperature and ensure smooth flow and filling of the plastic material throughout the molding process. The connection between the heating system 3 and the intelligent temperature control and detection system 6 ensures precise control during the heating process.

[0041] Furthermore, the first mounting base also includes a preheating air output pipe 204 connected to the preheating pipe 203, wherein the preheating pipe 203 is flat. The first mounting base includes a preheating air input interface 201, a preheating air control valve 202, and a preheating pipe 203. The preheating air input interface 201 is used to connect to a preheating air source, and the control valve manages the flow of preheating air. The preheating air control valve 202, connected to the control processing module 602, can precisely control and adjust the airflow and temperature entering the preheating pipe 203 according to actual needs. Within the first mounting base, the preheating pipe 203 is spirally positioned at the upper end of the injection molding channel 103, increasing the heat exchange area with the fluid and improving preheating efficiency. The preheating air heats the plastic within the injection molding channel 103 through the preheating pipe 203, ensuring good fluidity when injected into the mold.

[0042] Further explanation is provided: the heating system 3 includes a second mounting base and a third mounting base. The second and third mounting bases are connected to the injection molding flow channel 103. A first heating air input interface 301 is provided on one side of the second mounting base, and a second heating air input interface 302 is provided on one side of the third mounting base. The second mounting base is provided with a first heating air control valve 303, a second heating air control valve 308, a first heating tube 304, a second heating tube 306, a third heating tube 309, a first heating air output tube 305, a second heating air output tube 307, and a third heating air output tube 310. The first heating air control valve 303 and the second heating air control valve 308 are respectively connected to the control processing module 602. The first heating tube 304 is connected to the first heating air output tube 305, the second heating tube 306 is connected to the second heating air output tube 307, and the third heating tube 309 is connected to the third heating air output tube 310.

[0043] The second and third mounting brackets are connected to the middle and lower ends of the injection molding flow channel 103, respectively, and are responsible for further heating the injection molding flow channel 103. The second and third mounting brackets are respectively connected to the first and second heating air input interfaces 302, allowing external hot air sources to enter. The heating system 3 can work independently or in coordination. The two heating air control valves are also connected to the control processing module 602, which can adjust the flow rate of hot air entering the heating tube according to the actual temperature control requirements.

[0044] Furthermore, heating tube 304 and heating tube 306 are both arranged in a spiral manner at the middle of the injection molding flow channel 103, while heating tube 309 is arranged in a spiral manner at the lower end of the injection molding flow channel 103. The spiral arrangement of heating tubes 304, 306, and 309 at different positions (middle and lower end) of the injection molding flow channel 103 enhances the heat exchange between the fluid and the heating tubes, ensuring uniform temperature throughout the flow channel.

[0045] Furthermore, a guide rod 104 is provided between the upper mold base 101 and the lower mold base 102. A demolding system 5 is also provided on both sides of the lower mold base 102.

[0046] A guide rod 104 is provided between the upper mold base 101 and the lower mold base 102 to ensure good alignment of the upper and lower mold bases 102 during closing and opening, improving the stability and flatness of the mold. The core of the demolding system 5 lies in the high-pressure gas input interface 501 and the high-pressure gas delivery pipe 502. After the plastic part is molded, high-pressure gas is supplied to the gas delivery channel through the high-pressure gas input interface 501. The gas pushes the plastic part away from the core 802, reducing physical friction in the mold and preventing damage. The high-pressure gas delivery pipe 502 is directly connected to the gas delivery channel, ensuring that the gas can quickly reach the demolding area, improving demolding efficiency. The design of the gas delivery channel makes it more efficient and reduces resistance to gas flow.
