Description

Technical Field

[0001] This utility model relates to the field of deformation correction technology, and in particular to a simple deformation correction device that utilizes the protruding structure of the product itself. Background Technology

[0002] Plastic materials are widely used due to their excellent properties. However, the shrinkage properties of injection molding materials and the characteristics of reinforcing materials such as glass fiber, limited by the product structure, can significantly affect the flow of plastic materials, leading to warpage in injection molded products. Warpage cannot be resolved by adjusting injection molding process parameters during the injection molding process. It generally requires the use of complex corrective fixtures after injection molding to correct the product by deforming it in the opposite direction to the warpage. Each product requires a separate corrective fixture design, and currently there is no universally applicable solution.

[0003] Previous methods required product positioning fixtures and complex clamping and deformation mechanisms such as elbow clamps, which were complex in structure, high in manufacturing cost, long in processing cycle, and the straightening fixtures required frequent adjustments to the clamping amount.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0021] The following is combined with Figures 1 to 2 Specific embodiments of this utility model are described below: Figure 1 This is a side view of a simple deformation correction device that utilizes the protruding structure of a product, as provided by this utility model. Figure 2 This is a top view. This utility model provides a simple deformation correction device utilizing the product's own protruding structure, including an elastic pad 2, a pressure block 4, a supporting plane 1, and a loading counterweight 3. The simple deformation correction device is used to correct the bending of the component 5 to be corrected during processing and production. Here, the component 5 to be corrected is an injection-molded part, a long and narrow shell with protruding hook structures and bending deformation at both ends. During the production process of the injection-molded part, due to factors such as internal stress in the plastic, stress during processing, and uneven cooling, the bending at both ends will cause a banana-shaped bending deformation, and the deformation should be less than 1 mm. The surface of the component 5 to be corrected in this application has multiple surface protrusions, which are the protruding hook structures, and at least some of the surface protrusions are located at the edges of the component 5 to be corrected. In this embodiment, there are a total of five surface protrusions on the component 5 to be corrected, four of which are located at both ends of the component 5 to be corrected, and the remaining one is located in the middle of the component 5 to be corrected.

[0022] When correcting the component 5, the elastic pad 2 needs to be placed on the supporting plane 1, and then the middle part of the component 5 to be corrected is placed on the elastic pad 2, with the surface of the component 5 convex upwards. Due to the deformation pattern and characteristics of the component 5 to be corrected, its deformation also occurs towards the side with the convex surface. Here, the thickness of the elastic pad 2 is determined according to the deformation of the component 5 to be corrected, and the greater the deformation, the greater the thickness of the elastic pad 2. In this way, elastic pads 2 of different thicknesses can be used to adjust the effect of correcting deformation, thereby adapting to different deformations. The thickness range of the elastic pad 2 is 3mm to 5mm.

[0023] The pressure block 4 is then placed on the surface protrusion, and the deformation is corrected by pressing down on it. Here, the pressure block 4 has a groove inside, and assuming the surface protrusion is not wider at the top than at the bottom, the shape and depth of the groove are the same as the shape and height of the surface protrusion. This allows the shape of the groove to match the surface protrusion, and the surface protrusion can be accommodated within the groove. During the production process of the component 5 to be corrected, due to its shape, manufacturing process, etc., the deformation in various directions may not be completely consistent. However, if the component 5 is a mass-produced product, and its manufacturing process and shape follow clear specifications, the resulting deformation should be similar. Therefore, the weight of the pressure block 4 can vary; a heavier pressure block 4 is used in areas with more severe deformation, and a lighter one is used in areas with less deformation, thus effectively correcting the deformation and preventing some areas from being overcorrected while others are undercorrected. Furthermore, when the shapes of the surface protrusions are different, since the shape of the groove matches the surface protrusions, it can avoid incorrect placement when placing the pressure block 4 on the surface protrusions, and can ensure that pressure blocks 4 of different weights are placed in the appropriate positions.

[0024] After placing the pressure block 4, a counterweight 3 needs to be placed on top of the pressure block 4 to further add weight and ensure the corrective effect. Since the deformation is a banana-shaped bend, to correct this deformation, the weight needs to be applied to both ends. However, placing the weight of the counterweight 3 on the pressure block 4 located above the elastic pad 2 is not very effective and may even cause uneven deformation of the elastic pad 2, resulting in other deformations. Therefore, the counterweight 3 is a weight block with a notch, and when placing the counterweight 3 on the pressure block 4, the notch of the counterweight 3 needs to be aligned with the pressure block 4 located above the elastic pad 2, so that the counterweight 3 avoids the pressure block 4 located above the elastic pad 2.

[0025] This invention can correct the deformation of injection molded parts during the production process using relatively simple equipment, thereby providing reasonable correction force for the parts to be corrected and meeting the time requirements of rapid mass production.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
