Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment, and in particular to an injection molded part straightening device. Background Technology

[0002] During the molding process, injection molded parts are prone to warping, bending and other deformations due to factors such as uneven cooling, mold precision deviation, and inconsistent shrinkage at weak points in the structure. Therefore, it is very important to perform correction work on injection molded parts.

[0003] Chinese patent application number CN202021443348.5 provides a correction device for injection molded parts. This solution only requires clamping the plastic part between the pressure plate and the base plate for correction. It is convenient and quick to operate and has a low correction defect rate.

[0004] Existing injection molding straightening devices have a simple structure. During the straightening process, temperature may affect the material, causing excessive softening or insufficient temperature, which makes straightening difficult. Furthermore, the high temperature after straightening also makes it difficult to mold the injection parts. Therefore, we propose an injection molding straightening device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a correction device for injection molded parts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A straightening device for injection molded parts includes a straightening table, a base, a receiving frame, and two automatic push rods. Assembly frames are fixedly connected to the four corners of the upper end of the straightening table. An automatic push rod is fixedly connected to the outer end of the assembly frame. A positioning block is installed at the transmission end of the automatic push rod. A straightening box is snapped into the inner end of the positioning block. A pair of assembly slots are formed at the inner end of the straightening box. A temperature sensor is installed at the inner end of each assembly slot. An electric heating element is installed above the temperature sensor. Diverter pipes are installed on the outer sides of both ends of the straightening box. Cooling heads are fixedly connected to the outer ends of the diverter pipes and are evenly distributed.

[0008] By installing a straightening box and a manifold, the practicality of this injection molding straightening device can be improved, making it adaptable to different straightening molding needs.

[0009] Furthermore, each of the diverter pipes is fixedly connected to an air blower pipe at its outer end, and one end of each pair of air blower pipes is fixedly connected to a conveying pipe, with a fan fixedly connected to the outer end of the conveying pipe.

[0010] The installation of delivery pipes and air blowing pipes improved the usability of the structure.

[0011] Furthermore, a base is installed at the bottom of the correction table, and a support frame is installed at the top of the correction table. The support frame has a U-shaped structure, and an automatic push rod is installed at the top of the support frame.

[0012] By installing a support frame, the automatic push rod and the connected structure can operate more stably.

[0013] Furthermore, a reinforcing frame is installed at the transmission end of the automatic push rod 2, and an adjusting rod is slidably connected to each of the four corners of the inner end of the reinforcing frame. Limit heads are fixedly connected to both ends of the adjusting rod, and a reset ring is sleeved on the outer end of the adjusting rod.

[0014] By installing an adjusting rod and a reset ring, the device can be made more efficient in the process of straightening injection molded parts.

[0015] Furthermore, a straightening plate is installed at the bottom end of the adjusting rod, and a mounting frame is bolted to the bottom end of the straightening plate. A straightening component is fixedly connected to the bottom end of the mounting frame.

[0016] By setting up an installation frame, the ease of maintenance and use of this injection molding part straightening device is improved.

[0017] Furthermore, a heating element is installed at the inner end of the corrective component, and a high-temperature resistant silicone layer is fixedly connected to the bottom end of the corrective component.

[0018] By installing a high-temperature resistant silicone layer, the effectiveness of the device's corrective structure is improved.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting up a straightening box and a distribution pipe, when the device is performing straightening work, the injection molded part is located on the upper end of the electric heating plate inside the straightening box. The electric heating plate, together with the temperature sensor connected to the bottom, can sense the temperature of the electric heating plate in real time, so that the electric heating plate can maintain the normal value of heating the injection molded part. During the straightening process, the electric heating plate, together with the heatable straightening part and the high-temperature resistant silicone layer at the bottom, can adjust the heating at the outer end of the injection molded part. Using a heating structure with an appropriate temperature can soften the injection molded part locally, so that deformation can be straightened smoothly. After injection molding is completed, starting the fan can enable the distribution pipe to conduct air energy. Combined with the air blown from multiple cooling heads, the straightened workpiece can be cooled and formed quickly, so that it can be quickly solidified and shaped. This shortens the entire straightening operation cycle, improves production efficiency, and enhances the practicality of the injection molded part straightening device, making it adaptable to different straightening and forming needs.

[0028] Reference Figure 1-4As shown, a preferred embodiment of the present invention provides a straightening device for injection molded parts, comprising a straightening table 1, a base 2, a receiving frame 10, and an automatic push rod 11. Assembly frames 3 are fixedly connected to the four corners of the upper end of the straightening table 1. An automatic push rod 4 is fixedly connected to the outer end of the assembly frame 3. A positioning block 5 is installed on the transmission end of the automatic push rod 4. A straightening box 6 is snapped onto the inner end of the positioning block 5. A pair of assembly slots 8 are provided inside the straightening box 6. A temperature sensor 9 is installed inside the assembly slot 8. An electric heating element 7 is installed above the temperature sensor 9. Diverter pipes 23 are installed on the outer sides of both ends of the straightening box 6. Cooling heads 24 are fixedly connected to the outer ends of the diverter pipes 23, and the cooling heads 24 are evenly distributed. By installing the straightening box 6 and the diverter pipes 23, when the device performs straightening work, the electric heating element 7 located inside the straightening box 6... At the upper end of the heating element 7, the electric heating element 7, together with the temperature sensor 9 connected to the bottom, can sense the temperature of the electric heating element 7 in real time, so that the electric heating element 7 can maintain the normal value when heating the injection molded part. During the straightening process, the electric heating element 7, together with the heatable straightening element 18 and the high-temperature resistant silicone layer 19 at the bottom, can adjust the heating at the outer end of the injection molded part. Using a heating structure with an appropriate temperature can soften the injection molded part locally, so that deformation can be straightened smoothly. After the injection is completed, the fan 21 can be turned on so that the distribution pipe 23 can conduct wind energy. Combined with the air blown from multiple cooling heads 24, the straightened workpiece can be cooled and formed quickly, so that it can be quickly solidified and shaped, shortening the entire straightening operation cycle, improving production efficiency, and improving the practicality of the injection molded part straightening device, so that it can be adapted to different straightening and forming needs.

[0029] Reference Figure 1-2 As shown, each of the two branch pipes 23 is fixedly connected to a blower pipe 22 at its outer end. One end of each blower pipe 22 is fixedly connected to a conveying pipe 211. The outer end of the conveying pipe 211 is fixedly connected to a fan 21. By installing the conveying pipe 211 and the blower pipe 22, when the fan 21 is started, it can conduct air energy to the conveying pipe 211. The conveying pipe 211 then delivers the air energy to the blower pipe 22 for branching. This allows the two branch pipes 23 to conveniently conduct gas for heat conduction, improving the performance of the structure.

[0030] Reference Figure 1-3 As shown, a base 2 is installed at the bottom of the correction table 1, and a support frame 10 is installed at the top of the correction table 1. The support frame 10 has a U-shaped structure, and an automatic push rod 11 is installed at the top of the support frame 10. By installing the support frame 10, the support frame 10 can support the connecting structure at the outer end of the automatic push rod 11, making the automatic push rod 11 and the connected structure operate more stably.

[0031] Reference Figure 1-4As shown, a reinforcing frame 12 is installed at the transmission end of the automatic push rod 11. Adjusting rods 13 are slidably connected to the four corners of the inner end of the reinforcing frame 12. Limiting heads 14 are fixedly connected to both ends of the adjusting rods 13. A reset ring 15 is sleeved on the outer end of the adjusting rods 13. By installing the adjusting rods 13 and the reset ring 15, when the straightening plate 16 connected to the bottom of the adjusting rod 13 contacts the workpiece, the adjusting rod 13, in conjunction with the elastic reset ring 15, can adjust and reset its position under the action of the force. This allows the straightening plate 16 and the straightening component 18 to be conveniently adjusted for straightening, while also allowing for more precise calibration based on the position of the workpiece. This ensures the flexibility of the straightening plate 16 and the straightening component 18 in the straightening adjustment, making the device more efficient in the straightening process of injection molded parts.

[0032] Reference Figure 3-4 As shown, a straightening plate 16 is installed at the bottom of the adjusting rod 13. A mounting frame 17 is bolted to the bottom of the straightening plate 16. A straightening component 18 is fixedly connected to the bottom of the mounting frame 17. By setting up the mounting frame 17 and connecting it to the straightening plate 16 with bolts, it is very convenient to disassemble, maintain or replace structural components such as the straightening component 18, thus improving the convenience of structural maintenance and use of the injection molding straightening device.

[0033] Reference Figure 4 As shown, a heating element 20 is installed at the inner end of the straightening element 18, and a high-temperature resistant silicone layer 19 is fixedly connected to the bottom end of the straightening element 18. By installing the high-temperature resistant silicone layer 19, the straightening element 18 is made of thermally conductive aluminum plate or high-temperature resistant composite plate material. It can be straightened by moving under the transmission of the automatic push rod 11. The straightening element 18 and the high-temperature resistant silicone layer 19 connected to the bottom protect the workpiece in contact with the straightening, avoiding damage to the workpiece when the straightening element 18 is adjusted and straightened, thus improving the use effect of the straightening structure of the device.

[0034] Specific implementation process: When using this device, the heating component is turned on to the required temperature through the control system, and then the workpiece is placed on the upper end of the electric heating plate 7. The electric heating plate 7, together with the temperature sensor 9 connected at the bottom, can sense the temperature of the electric heating plate 7 in real time so that the electric heating plate 7 can maintain the normal value when heating the injection molded part. During the correction process, the electric heating plate 7, together with the heatable correction component 18 and the high temperature resistant silicone layer 19 at the bottom, can adjust the heating at the outer end of the injection molded part. Using a heating structure with an appropriate temperature can make the injection molded part locally soft, so that deformation correction can be carried out smoothly.

[0035] When the automatic push rod 11 is activated again, it can drive the straightening plate 16 and the straightening component 18 to adjust. During the movement, when the straightening plate 16 connected to the bottom of the adjusting rod 13 contacts the workpiece, the adjusting rod 13, in conjunction with the elastic reset ring 15, can adjust and reset its position under the action of the force. This allows the straightening plate 16 and the straightening component 18 to be easily adjusted for correction, while also allowing for more precise calibration based on the position of the workpiece. This ensures the flexibility of the straightening plate 16 and the straightening component 18 in the adjustment. The straightening component 18 is made of thermally conductive aluminum plate or high-temperature resistant composite plate material. It can be straightened by moving under the transmission of the automatic push rod 11. The straightening component 18 and the high-temperature resistant silicone layer 19 connected to the bottom provide protection on the outside of the workpiece being straightened, allowing the device to be easily adjusted for correction.

[0036] After the straightening is completed, multiple heating components stop heating and the fan 21 is started. After the fan 21 is started, it can conduct air energy to the conveying pipe 211. The conveying pipe 211 then delivers the air energy to the blowing pipe 22 for diversion. This allows a pair of diversion pipes 23 to conveniently conduct gas for heat conduction, which can accelerate the cooling and forming of the straightened workpiece, making it quickly solidify and set, shortening the entire straightening operation cycle and improving production efficiency.
