Technical Field
[0001] This utility model relates to the field of injection mold cooling technology, and in particular to a cooling and shaping device for automotive injection molded parts. Background Technology
[0002] Automotive injection molded parts refer to various plastic parts used in automobiles manufactured through injection molding. Injection molded parts cooling and solidification devices are used in the injection molding process to cool down the plastic products after injection molding, so that they can quickly solidify and solidify. Rapid cooling can shorten the molding cycle of injection molded parts, allowing the mold to proceed to the next injection molding cycle more quickly.
[0003] A search revealed that the document with publication number "CN214395290U" mentions "This application relates to a cooling and shaping device for injection molded parts, comprising a support assembly and a cooling assembly disposed on the support assembly. The support assembly also has a shaping assembly that cooperates with the cooling assembly. The shaping assembly includes a plurality of cylinders disposed on the support assembly and shaping molds disposed one-to-one with the cylinders. The shaping molds include a lower shaping mold disposed on the cooling assembly and an upper shaping mold disposed on the cylinders. The lower shaping mold is used to place the injection molded part to be cooled. When the piston rod of the cylinder extends, the upper shaping mold and the lower shaping mold..." The molds work together to limit the movement of the injection molded part. This application has the effect of preventing warping and deformation of the injection molded part during the cooling process. Its cooling effect is good, allowing the coolant to flow better within the cooling platform along the guide of the serpentine water channels, ensuring timely replacement of the coolant within the cooling platform. Furthermore, the water flow directions of the two serpentine water channels are opposite, thus ensuring that the cooling effect of the cooling platform is similar, improving the cooling efficiency of the injection molded part and guaranteeing the cooling effect of the cooling device. However, this device only provides cooling for the bottom of the mold, lacking top cooling, resulting in uneven cooling. This uneven cooling effect can lead to uneven shrinkage stress inside the injection molded part, causing deformation and affecting the dimensional accuracy and appearance quality of the product.
[0004] To address these issues, we provide a cooling and shaping device for automotive injection molded parts. Utility Model Content

[0014] 1. The heat dissipation components provide simultaneous cooling to the top and bottom of the mold, ensuring uniform cooling and providing pressure to ensure the mold's tightness, preventing deformation of the injection molded parts that could affect the product's dimensional accuracy and appearance. The drive motor provides power to rotate the drive gears, causing the two sets of transmission gears on both sides to rotate, which in turn rotates the transmission screw, causing the translation frame to move horizontally along the support frame. This brings the C-shaped heat-conducting plate into contact with the large area of the mold on both sides, and provides pressure to clamp the mold. Heat is transferred through the C-shaped heat-conducting plate to the solid heat-conducting pipe, and then the coolant in the heat-conducting hose absorbs the heat.

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.
[0022] Please see Figure 1-4 As shown, a cooling and shaping device for automotive injection molded parts includes a base 1 and a heat dissipation assembly 2. The heat dissipation assembly 2 is installed on one side of the top of the base 1. The heat dissipation assembly 2 includes a support frame 201 fixedly connected to one side of the top of the base 1. A translation frame 202 is slidably connected to the inner side of the support frame 201 through a slot. A C-shaped heat conduction plate 203 is fixedly connected to the upper side of one side of the translation frame 202.
[0023] Furthermore, an auxiliary bracket 204 is fixedly connected to the top of the C-shaped heat-conducting plate 203, and a sliding frame 205 is fixedly connected to the bottom of the C-shaped heat-conducting plate 203. The inner side of the sliding frame 205 is slidably connected to the support frame 201 through a slot. The auxiliary bracket 204 is fixedly connected to the support frame 201 to provide auxiliary support for the C-shaped heat-conducting plate 203. The sliding frame 205 moves with the C-shaped heat-conducting plate 203 to provide bottom auxiliary support, reducing the load-bearing deformation of the C-shaped heat-conducting plate 203.
[0024] Furthermore, the inner side of the translation frame 202 is threaded with a transmission screw 206, and one end of the transmission screw 206 is fixedly connected to a transmission gear 207. The transmission screw 206 and the support frame 201 form a rotating structure through a slot. The support frame 201 provides a limit for the transmission screw 206. Two sets of transmission gears 207 are symmetrically distributed, and the two sets of symmetrically arranged transmission screws 206 and translation frame 202 are connected.
[0025] Furthermore, a drive motor 208 is installed on one side of the support frame 201. One end of the drive motor 208 is connected to a drive gear 209 via a shaft key. The outer side of the drive gear 209 meshes with the transmission gear 207. The drive motor 208 provides power to drive the drive gear 209 to rotate, causing the two sets of transmission gears 207 distributed on both sides to rotate accordingly, driving the transmission screw 206 to rotate, so that the two sets of translation frames 202 move horizontally towards or away from each other along the support frame 201.
[0026] Furthermore, a solid heat pipe 210 is fixedly connected to the inner side of the C-shaped heat-conducting plate 203. A heat-conducting hose 211 is sleeved inside the solid heat-conducting pipe 210. A pump 212 is installed at one end of the heat-conducting hose 211. A storage tank 213 is installed at the bottom of the pump 212. A cooling plate 214 is installed on one side of the storage tank 213. The other end of the heat-conducting hose 211 is connected to the storage tank 213. The C-shaped heat-conducting plate 203 abuts against the large area of the forming mold 8 on both sides and provides pressure to clamp the forming mold 8. Heat is transferred to the solid heat-conducting pipe 210 through the C-shaped heat-conducting plate 203. Then, the coolant in the heat-conducting hose 211 absorbs the heat. The pump 212 provides power to drive the coolant circulation. The cooling plate 214 works in conjunction with the cooling of the coolant to ensure the heat absorption effect of the coolant.
[0027] Furthermore, a limiting block 3 is fixedly connected to the other side of the top of the base 1. An electric telescopic rod 4 is installed on the top of the limiting block 3. A bracket 5 is fixedly connected to the telescopic end of the electric telescopic rod 4. The bracket 5 and the limiting block 3 form a sliding structure through a slot. The extension and retraction of the electric telescopic rod 4 drives the bracket 5 to move horizontally along the slot of the limiting block 3, thereby displacing the shaping mold 8 and facilitating the transfer of the shaping mold 8 before and after cooling.
[0028] Furthermore, an extension frame 6 is fixedly connected to the outer end of the bracket 5. A limiting screw 7 is threadedly connected to the inner side of the extension frame 6. A shaping mold 8 is inserted into the inner side of the bracket 5 through a slot. The shaping mold 8 is inserted into the slot of the bracket 5, and the limiting screw 7 rotates inside the extension frame 6 to make the inner end of the limiting screw 7 abut against the shaping mold 8 to complete the fixation, providing a certain degree of flexibility and applicability.
[0029] Working principle: In use, firstly, the shaping mold 8 is inserted into the slot of the bracket 5. The limiting screw 7 rotates inside the extension frame 6, causing its inner end to abut against the shaping mold 8 for fixation. The electric telescopic rod 4 extends and retracts, causing the bracket 5 to move along the slot of the limiting block 3 to the vicinity of the C-shaped heat-conducting plate 203. Secondly, the drive motor 208 provides power to rotate the drive gear 209, causing the two sets of transmission gears 207 on both sides to rotate accordingly, driving the transmission screw 206 to rotate, causing the two sets of translation frames 202 to move towards each other along the support frame 201. Thirdly, the C-shaped guide... The hot plate 203 abuts against the large area of the mold 8 on both sides, and provides pressure to clamp the mold 8. Heat is transferred to the solid heat pipe 210 through the C-shaped heat conduction plate 203, and then the coolant in the heat conduction hose 211 absorbs the heat. The pump 212 provides power to drive the coolant circulation, and works with the cooling plate 214 to cool the coolant to ensure the heat absorption effect of the coolant. In the fourth step, after cooling is completed, the C-shaped heat conduction plate 203 moves to both sides, and the electric telescopic rod 4 extends and retracts to drive the bracket 5 to send out the mold 8. This completes the use of a cooling and shaping device for automotive injection molded parts.
