Description

Technical Field

[0001] This utility model relates to the field of injection molding production technology, and in particular to a post-cooling device for injection molded parts. Background Technology

[0002] Currently, injection molding is a highly efficient and widely used plastic processing technology. It primarily involves injecting molten plastic into a mold cavity, where it cools and solidifies to form the final product. This is mainly achieved through an injection molding machine. The process includes mold closing, preparation for injection, filling, injecting molten plastic into the mold under high pressure, holding pressure to compensate for shrinkage, cooling (which takes up most of the cycle), and finally, mold opening and demolding to remove the finished product, completing one cycle.

[0003] However, in actual production, most products are cooled directly in the injection molding machine. For some products with a large thickness, the cooling effect in the middle is poor after the mold is opened and the product is removed, which affects the product quality. Therefore, improvement is needed. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a post-cooling device for injection molded parts, which can improve the cooling effect of the product and reduce the product defect rate.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A post-cooling device for injection molded parts includes a cooling water tank, a draining tank, and a drying tank arranged sequentially. The workpiece to be cooled is placed in a storage frame with a hollow mesh structure. The storage frame can be placed in the cooling water tank, the draining tank, and the drying tank. The cooling water in the cooling water tank is higher than the top of the workpiece in the storage frame. The device also includes a blower assembly, which includes a blower and several ventilation pipes. Each ventilation pipe is connected to the air outlet of the blower. Each ventilation pipe passes through the cooling water tank, the draining tank, and the drying tank in sequence. Each ventilation pipe includes a heat exchange section, a draining section, and a drying section arranged sequentially. The heat exchange section, the draining section, and the drying section are respectively located in the cooling water tank, the draining tank, and the drying tank. Each drying section is provided with several ventilation holes.

[0007] By adopting the above technical solution, and by setting up a cooling water tank, a draining tank, an air drying tank, a storage frame, and a blower assembly, the injection molded parts can be cooled, drained, and dried, thereby improving the cooling effect and reducing the product defect rate. In this application, the workpiece to be cooled can be placed in the storage frame, and then the storage frame can be placed in the cooling water tank. After cooling, the storage frame can be transferred to the draining tank to drain most of the water adhering to the workpiece. Then, the storage frame can be transferred to the air drying tank, where hot air blown out of the ventilation pipe can be used to air dry the workpiece. After air drying, the workpiece can be removed. This cycle can achieve the cooling, draining, and air drying operations of the workpiece. The advantage of this application is that the cooling effect of the cooling water can be used to transfer heat energy to the cooling water. The heat energy in the cooling water can be transferred to the inner wall of the ventilation pipe through the outer wall of the ventilation pipe. The blower blows air into the ventilation pipe, and the airflow carries the heat energy of the inner wall of the ventilation pipe to the ventilation holes at the air drying tank for air drying of the workpiece surface.

[0008] In one possible implementation, each of the ventilation pipes is divided into several support pipes and several limiting pipes. Each of the support pipes is supported on the lower side of the storage frame, and each of the limiting pipes is located on one side of the storage frame. The ventilation holes of each of the ventilation pipes blow air towards the inside of the storage frame, and the installation position of each of the limiting pipes is lower than the water level of the cooling water tank.

[0009] By adopting the above technical solution, the setting of support tubes and limiting tubes can achieve two functions: first, limiting and stabilizing the storage frame; second, the cooling tank can achieve timely and balanced heat dissipation of the cooling water in the upper and lower parts of the cooling tank; and third, the air-drying tank section can achieve uniform air-drying of the workpieces in the storage frame from multiple angles.

[0010] In one possible implementation, the connection between each of the ventilation pipes and the cooling water tank is sealed by full welding.

[0011] By adopting the above technical solution, the waterproof sealing of each heat dissipation pipe and the cooling water tank is improved by using a full-welded sealing connection.

[0012] In one possible implementation, each heat exchange section has a plurality of heat dissipation fins on its inner wall, each heat dissipation fin is arranged along the axis of the ventilation duct, and each heat dissipation fin is arranged circumferentially around the axis of the ventilation duct.

[0013] By adopting the above technical solution and setting up several heat dissipation fins, the heat dissipation performance of the heat exchange section will be further improved.

[0014] In one possible implementation, a shroud is provided on one side of the cooling water tank, and the shroud and the cooling water tank enclose a main ventilation cavity. The air outlet of the main ventilation cavity is connected to the air inlet of each of the ventilation pipes, and the air inlet of the main ventilation cavity is connected to the air outlet of the blower.

[0015] By adopting the above technical solution, the installation of the hood will facilitate the connection between the blower and each ventilation pipe.

[0016] In one possible implementation, the main ventilation cavity is provided with a drainage protrusion, which is spherically shaped to guide the diverted flow to the air inlets of each of the surrounding ventilation ducts.

[0017] By adopting the above technical solution, the setting of the diversion bulge can guide the airflow entering the main ventilation cavity according to the arrangement of each ventilation pipe, thereby improving the smoothness of airflow.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. By setting up a cooling water tank, a draining tank, a drying tank, a storage frame, and a blower assembly, the injection molded parts are cooled, drained, and dried, improving the cooling effect and reducing the defect rate. In this application, the workpiece to be cooled is placed in the storage frame, and then the storage frame is placed in the cooling water tank. After cooling, the storage frame is transferred to the draining tank to drain most of the water adhering to the workpiece. Then, the storage frame is transferred to the drying tank, where hot air blown from the ventilation pipe dries the workpiece. After drying, the workpiece is removed. This cycle can achieve the cooling, draining, and drying operations of the workpiece. The advantage of this application is that the cooling effect of the cooling water can transfer heat energy to the cooling water. The heat energy in the cooling water is transferred to the inner wall of the ventilation pipe through the outer wall of the ventilation pipe. The blower blows air into the ventilation pipe, and the airflow carries the heat energy from the inner wall of the ventilation pipe to the ventilation holes at the drying tank for spraying out, thus drying the surface of the workpiece.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a post-cooling device for injection molded parts. (Refer to...) Figures 1-3 As shown, the system includes a cooling water tank 1, a draining tank 2, and a drying tank 3 arranged sequentially. The workpiece to be cooled is placed in a square, hollowed-out mesh-like trough frame 4. The frame 4 can be placed sequentially in the cooling water tank 1, the draining tank 2, and the drying tank 3. The cooling water level in the cooling water tank 1 is higher than the top of the workpiece in the frame 4. The system also includes a blower assembly, which includes a blower 5 and several ventilation pipes 6. Each ventilation pipe 6 is connected to the air outlet of the blower 5. Each ventilation pipe 6 passes through the cooling water tank 1, the draining tank 2, and the drying tank 3 in sequence. Each ventilation pipe 6 includes a heat exchange section 601, a draining section 602, and a drying section 603 connected sequentially. The heat exchange section 601, the draining section 602, and the drying section 603 are respectively located in the cooling water tank 1, the draining tank 2, and the drying tank 3. Each drying section 603 is provided with several ventilation holes 7.

[0027] The ventilation pipes 6 are divided into several support pipes 61 and several limiting pipes 62 according to their installation positions. In this embodiment, there are two limiting pipes 62, respectively located on both sides of the storage frame 4, and three support pipes 61, all located on the lower side of the storage frame 4. The ventilation holes 7 of each ventilation pipe 6 blow air towards the inside of the storage frame 4. The installation position of each limiting pipe 62 is lower than the water level of the cooling water tank 1, which facilitates more comprehensive heat dissipation of the cooling water in the cooling water tank. Specifically, the ventilation holes 7 on each support pipe 61 are all set upwards, and the ventilation holes 7 of the two limiting pipes 62 are all set diagonally downwards towards the inside of the storage frame 4.

[0028] To ensure the airtightness of each ventilation pipe 6 and the cooling water tank 1, the connection between each ventilation pipe 6 and the cooling water tank 1 is sealed by full welding.

[0029] In order to improve the heat dissipation efficiency of each ventilation duct 6, a number of heat dissipation fins 8 will be fixed on the inner wall of each heat exchange section 601. Each heat dissipation fin 8 is arranged along the axis of the ventilation duct 6 and is arranged circumferentially around the axis of the ventilation duct 6. The width of each heat dissipation fin 8 is smaller than the inner wall radius of the heat exchange section 601.

[0030] Furthermore, a fan shroud 9 is fixed on one side of the cooling water tank 1. The fan shroud 9 and the cooling water tank 1 enclose a closed ventilation main cavity 10. The air outlet of the ventilation main cavity 10 is connected to the air inlet of each ventilation pipe 6. The air inlet of the ventilation main cavity 10 is connected to the air outlet of the blower 5.

[0031] To improve the airflow stability within the main ventilation chamber 10, a drainage protrusion 11 will be fixed inside the main ventilation chamber 10. The drainage protrusion 11 is spherical and is mainly used to guide the airflow to the air inlet of each ventilation pipe 6 on the periphery.

[0032] The implementation principle of the injection molding post-cooling device in this application embodiment is as follows: the blower 5 is turned on to ventilate each ventilation pipe 6. The workpieces to be cooled after being removed from the injection molding equipment are placed in the storage frame 4. After accumulating a specified number, the storage frame 4 is placed in the cooling water tank 1. After cooling is completed, the storage frame 4 is taken out and transferred to the drain tank 2 to drain most of the water attached to the workpiece and the storage frame 4. At this time, the next storage frame 4 can be placed in the cooling water tank 1. When the specified time is reached, the storage frame 4 in the drain tank 2 is transferred to the air drying tank 3. The hot air blown out of the ventilation pipe 6 is used to air dry the workpiece. At this time, the next storage frame 4 can be taken out from the cooling water tank 1 and placed in the drain tank 2. Then the next storage frame 4 is placed in the cooling water tank 1. After air drying is completed, the workpiece is taken out, and each storage frame 4 is taken out and placed in the next level tank in sequence. The post-cooling, draining and air drying operations of the injection molding parts are completed in this cycle.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
