[0025] Embodiment one

[0026] Please refer to Figures 1-5 The cooling device for injection molding part production of the present embodiment, including cooling pool 1 and setting in the cooling pool 1 inside bearing plate 2.

[0027] Cooling pool 1: as the main part of the cooling device, the cooling pool 1 provides a space containing cooling water and injection molding parts. It usually has enough depth and width to accommodate injection molding parts of different sizes and shapes. The two sides of the center of the cooling pool 1 are provided with lifting modules, which provide power support for the up and down movement of the bearing plate 2.

[0028] Carrying plate 2: Carrying plate 2 is arranged inside the cooling pool 1, used to directly carry the injection molded parts. Its top is designed with several through slots, which allow cooling water or cooling medium to pass through, fully contact with the injection molded parts, thereby improving the cooling efficiency. The two sides of the carrying plate 2 are also connected with the lifting bracket 4, which can move up and down with the action of the lifting module.

[0029] Lifting module: The lifting module is the key component of the cooling device to realize the up and down movement of the carrying plate 2. Each lifting module contains a protective shell 7 and a lifting cylinder 5 installed inside the protective shell 7. The protective shell 7 not only provides protection for the lifting cylinder 5, but also allows the lifting bracket 4 to pass through the lifting groove 15 opened on one side of the protective shell 7. The lifting cylinder 5 serves as a power source, connected to the lifting bracket 4 through its output end, driving the carrying plate 2 to move accurately up and down inside the cooling pool 1.

[0030] Protective shell 7: The protective shell 7 is the outer protective structure of the lifting module, which effectively isolates the lifting cylinder 5 from the external environment, preventing dust, moisture and other impurities from eroding the cylinder. At the same time, the lifting groove 15 opened on one side of the protective shell 7 provides a necessary channel for the lifting bracket 4, ensuring smooth lifting action.

[0031] Lifting cylinder 5: The lifting cylinder 5 is the core power component of the lifting module. It performs extension and retraction movement according to the control signal, and transmits power to the carrying plate 2 through its output end connected to the lifting bracket 4, realizing the up and down movement of the carrying plate inside the cooling pool 1. The stability and reliability of the lifting cylinder 5 directly affect the overall performance of the cooling device.

[0032] Lifting bracket 4: The lifting bracket 4 is an important component connecting the carrying plate 2 and the lifting cylinder 5. One end of it is tightly connected with the carrying plate 2, and the other end extends into the lifting groove 15 and is connected with the output end of the lifting cylinder 5. The design of the lifting bracket 4 ensures the stability of the lifting action and the carrying capacity, so that the injection molded parts can maintain a stable position during the cooling process.

[0033] The two sides of the cooling pool 1 are provided with lifting modules, and the top of the carrying plate 2 is provided with lifting brackets 4 on both sides. The lifting module contains a protective shell 7 and a lifting cylinder 5 installed inside the protective shell 7. The protective shell 7 is provided with a lifting groove 15 on one side, and one end of the lifting bracket 4 is connected with the carrying plate 2, and the other end extends into the lifting groove 15 and is connected with the output end of the lifting cylinder 5.

[0034] Example two

[0035] Please refer to Figures 1-5As shown, the cooling device for injection molding part production of the embodiment, the top of the bearing plate 2 is provided with a plurality of through grooves, one side of the cooling pool 1 is provided with a cooling circulation module 3 for cooperating with the cooling pool 1, the top of the bearing plate 2 is provided with a guide column 9 penetrating the bearing plate 2 through a sliding sleeve at four corners, the bottom end of the guide column 9 is connected with the bottom of the inner cavity of the cooling pool 1, and the top end is connected with the inner wall of the cooling pool 1 through a fixing plate 8. Specifically, the cooling water or cooling medium in the cooling pool 1 can be in full contact with the injection molding part through the cooperation of the plurality of through grooves on the top of the bearing plate 2 and the cooling circulation module 3, and the cooling circulation module 3 ensures the circulation of the cooling water or medium in the cooling pool 1, which continuously takes away the heat of the injection molding part. This working process improves the cooling efficiency and ensures the uniform cooling of the injection molding part, avoiding the deformation or quality problems of the injection molding part caused by uneven cooling.

[0036] The top of the bearing plate 2 is connected with a limiting frame 6, the limiting frame 6 is rectangular in shape, and the height of the limiting frame 6 is greater than the thickness of the bearing plate 2. Specifically, the limiting frame 6 connected to the top of the bearing plate 2 can limit the movement range of the injection molding part during the cooling process, avoiding the injection molding part from deviating from the predetermined position due to water flow or external force. At the same time, the limiting frame 6 is rectangular in shape and the height is greater than the thickness of the bearing plate 2, which ensures the limiting effect while not affecting the circulation of the cooling water. This working process improves the positioning accuracy and cooling effect of the injection molding part, further improving the overall performance of the equipment.

[0037] Embodiment three

[0038] Please refer to Figures 1-5 As shown, the cooling device for injection molding part production of the embodiment, the protective shell 7 is provided with a plurality of ventilation grooves 14 on one side, and the lifting cylinder 5 is connected with the inside of the protective shell 7 through a mounting bracket 11. Specifically, the heat generated by the lifting cylinder 5 during work can be effectively dissipated through the plurality of ventilation grooves 14 provided on one side of the protective shell 7, avoiding the performance decline or failure caused by overheating of the cylinder. At the same time, the lifting cylinder 5 is stably connected with the inside of the protective shell 7 through the mounting bracket 11, ensuring the stable operation of the cylinder and the long service life. This working process improves the stability and reliability of the equipment, reducing the maintenance cost.

[0039] The length of the lifting plate one 10 and the lifting plate two 13 is greater than the height of the cooling pool 1, and the width of the connecting plate 12 is greater than the thickness at the edge of the cooling pool 1. Specifically, by setting the length of the lifting plate one 10 and the lifting plate two 13 to be greater than the height of the cooling pool 1, and the width of the connecting plate 12 to be greater than the thickness at the edge of the cooling pool 1, the lifting support 4 can always remain stable during lifting and will not be blocked or deviated by the edge of the cooling pool 1. This working process improves the lifting flexibility and adaptability, so that the equipment can be applied to cooling pools and injection molded parts of different sizes.

[0040] The lifting support 4 comprises the lifting plate one 10 arranged outside the cooling pool 1 and the lifting plate two 13 arranged inside the cooling pool 1. One end of the lifting plate one 10 is connected with the output end of the lifting cylinder 5, and one end of the lifting plate two 13 is connected with the top of the bearing plate 2. The lifting plate one 10 and the lifting plate two 13 are connected through the connecting plate 12. Specifically, by the cooperation of the lifting plate one 10, the lifting plate two 13 and the connecting plate 12 included in the lifting support 4, the output force of the lifting cylinder 5 can be stably transmitted to the bearing plate 2, realizing the stable lifting of the bearing plate 2 in the cooling pool 1. Among them, the lifting plate one 10 is connected with the output end of the lifting cylinder 5, and the lifting plate two 13 is connected with the top of the bearing plate 2, and the two are tightly connected through the connecting plate 12. This working process improves the lifting stability and carrying capacity, ensuring the safety of the injection molded part during cooling.

[0041] The present scheme has the following working process:

[0042] Firstly, after the injection molded part is formed by the injection molding machine, it is placed on the bearing plate 2 inside the cooling pool 1. The top of the bearing plate 2 is provided with a plurality of through grooves, which cooperate with the cooling circulating module 3 installed on one side of the cooling pool 1, so that the cooling water or cooling medium in the cooling pool 1 can fully contact the injection molded part through the through grooves. The cooling circulating module 3 ensures the circulation of the cooling water or medium in the cooling pool 1, continuously taking away the heat of the injection molded part, thereby improving the cooling efficiency and ensuring the uniform cooling of the injection molded part, effectively avoiding the deformation or quality problems of the injection molded part caused by uneven cooling.

[0043] Then, according to the cooling requirement of the injection molded part, the lifting module starts to work. The lifting module is composed of a protective shell 7 and a lifting cylinder 5 installed inside the protective shell 7, and a lifting groove 15 is formed on one side of the protective shell 7. The top of the bearing plate 2 is provided with a lifting support 4 on both sides, one end of which is connected with the bearing plate 2 and the other end extends into the lifting groove 15 and is connected with the output end of the lifting cylinder 5. After the lifting cylinder 5 is started, the bearing plate 2 is driven by the lifting support 4 to move up and down inside the cooling pool 1. This design not only facilitates the adjustment of the position of the injection molded part in the cooling pool according to its different sizes and cooling requirements, but also further ensures the uniformity and efficiency of cooling.

[0044] The structure of the lifting support 4 plays a key role in the lifting process. It contains the lifting plate one 10 arranged outside the cooling pool 1 and the lifting plate two 13 arranged inside the cooling pool 1, which are tightly connected through the connecting plate 12. One end of the lifting plate one 10 is connected with the output end of the lifting cylinder 5, and one end of the lifting plate two 13 is connected with the top of the bearing plate 2. This structure enables the output force of the lifting cylinder 5 to be stably transmitted to the bearing plate 2, achieving smooth lifting of the bearing plate 2 in the cooling pool 1, improving lifting stability and carrying capacity, and ensuring the safety of the injection molded parts during the cooling process.

[0045] In addition, the lengths of the lifting plate one 10 and the lifting plate two 13 are both greater than the height of the cooling pool 1, and the width of the connecting plate 12 is also greater than the thickness at the edge of the cooling pool 1. Such design enables the lifting support 4 to remain stable during the lifting process, without being blocked or deviated by the edge of the cooling pool 1, improving lifting flexibility and adaptability, so that the equipment can be applied to cooling pools and injection molded parts of different sizes.

[0046] At the same time, the several ventilation slots 14 opened on one side of the protective shell 7 also play an important role. They enable the heat generated by the lifting cylinder 5 during work to be effectively dissipated through the ventilation slots 14, avoiding performance degradation or failure caused by overheating of the cylinder. The lifting cylinder 5 is also stably connected with the inside of the protective shell 7 through the mounting bracket 11, ensuring stable operation of the cylinder and long service life.

[0047] Finally, after the cooling is completed, the lifting cylinder 5 is started again to lift the bearing plate 2 together with the cooled injection molded parts on it above the cooling pool 1 through the lifting support 4. During this process, the limiting frame 6 connected to the top of the bearing plate 2 plays a key role. The limiting frame 6 is rectangular in shape and has a height greater than the thickness of the bearing plate 2, which can limit the movement range of the injection molded parts during the cooling process, avoiding the injection molded parts from deviating from the predetermined position due to water flow or external force. At the same time, the design of the limiting frame 6 also ensures that the limiting effect does not affect the circulation of cooling water, further improving the positioning accuracy and cooling effect of the injection molded parts.

[0048] In summary, the technical scheme through the precise cooperation and unique design of each component not only solves the problem of difficulty in lifting the cooled injection molded parts, but also exhibits significant beneficial effects in improving cooling efficiency, ensuring uniformity of cooling, improving lifting stability and carrying capacity, enhancing adaptability and flexibility of the equipment, reducing maintenance cost, and improving overall performance of the equipment.
