Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to an injection molding product deformation correction device containing double-screw bolts. Background Art

[0002] Glass fiber reinforced plastic materials are widely used due to their excellent performance. However, due to the influence of shrinkage and glass fiber orientation, and the influence of product structure on material flow, injection molded products generally have warping problems. Product warping cannot be solved by adjusting injection molding process parameters. Usually, a complex correction device is required to correct the product in the opposite direction of the warping. This puts forward the requirements of reliability, simple operation and low cost for the design of the correction device. Summary of the invention

[0003] In order to solve the problem of warping and deformation of glass fiber reinforced plastic injection molding products, the utility model provides a

[0004] The deformation correction device for injection molded products with double-screw bolts uses double-screw bolts and locking nuts to reliably connect the correction jig with the toggle clamp head, so that the correction jig and the toggle clamp can move simultaneously, and the product can be corrected in the opposite direction. At the same time, the double-screw bolts and nuts also ensure the position accuracy of the correction jig. By simply rotating the double-screw bolts, the toggle clamp head can move towards each other or away from each other, thereby adjusting the pressing height position of the correction jig to achieve the function of adjusting the correction deformation amount. Achieve reliable, simple and low-cost correction requirements.

[0005] The technical solution of the utility model is: a deformation correction device for injection molded products containing double-screw bolts,

[0006] It includes a base, a bracket, an elbow clamp, a double-rotation bolt, a correction jig and a support block. The four support blocks are respectively arranged at the four corners of the base. The bracket is L-shaped and arranged at the upper end of the base; the pressure head end of the elbow clamp is arranged at the right-handed threaded end of the double-rotation bolt and is locked by a right-handed nut, and the elbow clamp body is arranged at the end of the horizontal part of the bracket; the correction jig matches the shape of the product, is arranged at the left-handed threaded end of the double-rotation bolt, and is locked by a left-handed nut.

[0007] In the above technical solution, the middle of the double-rotation bolt is the position of the wrench slot, the upper end is a right-hand thread end, which is consistent with the rotation direction of the threaded hole of the elbow clamp pressure head, and the lower end is a left-hand thread end, which matches the thread of the mounting hole on the correction fixture;

[0008] The beneficial effects of the utility model are: using double-rotation bolts and right-handed nuts and left-handed nuts, the toggle clamp and the correction fixture can be reliably connected, so that the toggle clamp and the correction fixture can move simultaneously, ensuring the position accuracy of the correction fixture. At the same time, it avoids the operations of placing the correction fixture separately and aligning the position, thereby improving the correction accuracy and efficiency.

[0009] By using a double-rotation bolt, the distance between the toggle clamp and the correction fixture at both ends of the bolt can be reduced or increased at the same time. By rotating the double-rotation bolt, the distance between the toggle clamp and the correction fixture can be adjusted while keeping the relative position of the toggle clamp and the correction fixture unchanged, that is, the pressing position of the correction fixture can be adjusted, and the correction deformation can be flexibly adjusted.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, a deformation correction device for injection molded products containing double-screw bolts comprises a base 1, a bracket 2, a toggle clamp 3, a double-screw bolt 4, a right-handed nut 5, a left-handed nut 6, a correction fixture 7 and a support block 9. The correction fixture 7 matches the shape of the product 8. The middle of the double-screw bolt 4 is a wrench groove 4-3, one end of which is processed into a right-handed thread end 4-1, which is consistent with the threaded hole direction of the toggle clamp 3 pressure head 3-1, and the other end is processed into a left-handed thread end 4-2, which matches the thread of the mounting hole on the correction fixture 7; support blocks 9 are respectively installed at the four corners of the base 1, and the L-shaped bracket 2 is fixed to the bottom. At the upper end of the seat 1, the right-handed threaded end 4-1 of the double-rotation bolt 4 is screwed into the threaded hole of the pressure head 3-1 of the toggle clamp 3 and locked with a right-handed nut 5; the other end of the pressure head 3-1 uses a nut to fix the main body of the toggle clamp 3 to the end of the horizontal part of the bracket 2, and the left-handed threaded end 4-2 of the two-way bolt 4 is screwed into the mounting threaded hole of the correction fixture 7 and locked with a left-handed nut 6. Rotating the wrench slot 4-3 of the double-rotation bolt can make the toggle clamp 3 and the correction fixture 7 approach or move away from each other at the same time, so as to achieve the purpose of adjusting the pressing height of the fixture and the purpose of being able to simply adjust the correction amount of the correction fixture 7.

[0015] When in use, it is divided into two parts: adjustment jig and correction product.

[0016] Adjust the fixture as follows:

[0017] Open the toggle clamp 3, and the pressure head 3-1 of the toggle clamp 3 reaches the maximum height. Screw the right-handed nut 5 and the left-handed nut 6 onto the double-rotation bolt 4 and adjust the positions symmetrically.

[0018] Screw the right-hand thread end 4-1 of the double-thread bolt 4 into the pressure head 3-1 of the toggle clamp 3, and lock the right-hand nut 5;

[0019] Screw the correction fixture 7 into the left-handed thread end 4-2 of the double-rotation bolt 4, and lock the left-handed nut 6;

[0020] Place the product 8 on the support block 9 and press down the toggle clamp 3;

[0021] Loosen the right-handed nut 5 and the left-handed nut 6, rotate the wrench slot 4-3 of the double-rotation bolt 4, adjust the height of the correction fixture 7 upward or downward, and re-tighten the right-handed nut 5 and the left-handed nut 6 when the correction position is reached.

[0022] Correct the product as follows: open the toggle clamp 3, and the toggle clamp 3 drives the correction fixture 7 to reach the maximum height. Put the product 8 in, press the toggle clamp 3 to drive the correction fixture 7 to press on the product 8, so that the product produces reverse deformation and completes the correction.
