[0028] Reference Figure 1 A correction system includes: a fixed die base 100, a magnetic member 300 and a movable die base 700. The fixed die base 100 is provided with a cavity 150, and the cavity 150 is used to place a workpiece; the magnetic member 300 is arranged on the fixed die base 100, and there are multiple magnetic members 300, each of which surrounds the side of the cavity 150 and can apply a directional magnetic field to the cavity 150; the movable die base 700 is movably connected to the fixed die base 100, and the movable die base 700 can move close to the fixed die base 100 and cover the cavity 150, and the movable die base 700 can move away from the fixed die base 100. The magnetic member 300 will form a directional magnetic field around the cavity 150, so that after the magnetic workpiece is placed in the cavity 150 manually or by a robot, the magnetic workpiece will be offset under the action of the magnetic field. Therefore, by presetting the orientation and other states of the magnetic suction component 300, the movement trajectory of the workpiece guided by the magnetic field can be determined, and then the workpiece and the cavity 150 can be automatically guided directly and effectively through the magnetic field formed by the magnetic suction component 300, so that the workpiece can automatically achieve the correction effect with the cavity 150 after being placed in the cavity 150, and the problem of damage to the mold and the workpiece caused by misalignment of the workpiece can be avoided.

[0029] In certain embodiments, reference Figure 4 There are two magnetic members 300, which are symmetrically distributed on both sides of the cavity 150, and the magnetic poles of the two magnetic members 300 are opposite to each other. The two magnetic members 300 can effectively form positive and negative magnetic poles of the magnetic field on both sides of the cavity 150, thereby directly and effectively forming a magnetic field around the cavity 150 for guiding the workpiece, so that the workpiece can be effectively automatically corrected after being placed in the cavity 150.

[0030] It is conceivable that only a single magnetic member 300 may be provided on the upper and lower sides of the cavity 150, and the magnetic properties may be formed by the magnetic member 300 itself. The specific implementation method may be adjusted accordingly according to actual needs, and is not limited here.

[0031] In certain embodiments, reference Figure 3, mounting holes 130 are provided on both sides of the fixed mold base 100, and the mounting holes 130 extend from the outer wall of the fixed mold base 100 to the cavity 150, and the magnetic member 300 is installed in the mounting holes 130. The mounting holes 130 not only allow the magnetic member 300 to be smoothly and effectively installed on the fixed mold base 100, but also the mounting holes 130 can perform relative positioning between the fixed mold base 100 and the magnetic member 300, thereby ensuring that the magnetic member 300 can accurately form a predetermined magnetic field around the cavity 150, thereby ensuring that the workpiece can smoothly obtain the automatic correction effect of the magnetic field on it.

[0032] In certain embodiments, reference Figure 2 , the cavity 150 is arranged in the middle of the top of the fixed mold base 100, and the mounting hole 130 extends obliquely from the outer side of the bottom end of the fixed mold base 100 to the middle of the top of the fixed mold base 100. The cavity 150 located in the middle of the top of the fixed mold base 100 allows the workpiece to be placed conveniently and avoids the structure of the fixed mold base 100 from interfering with the placement process of the workpiece. The oblique setting of the mounting hole 130 not only allows the mounting hole 130 to be exposed from the side of the fixed mold base 100, but also ensures that the mounting hole 130 can guide the magnetic suction member 300 to the cavity 150, so that the magnetic suction member 300 can apply magnetic force to the workpiece in the cavity 150.

[0033] In certain embodiments, reference Figure 3 The fixed die base 100 is provided with a blanking hole 190, the mold cavity 150 is connected to the blanking hole 190, and each magnetic attraction member 300 is distributed around the blanking hole 190. The blanking hole 190 allows waste materials to be discharged smoothly during mold processing, and the surrounding distribution of the magnetic attraction members 300 can ensure that the magnetic field effect caused by the magnetic attraction members 300 on the falling waste materials is always balanced, thereby preventing the falling waste materials from being blocked in the blanking hole 190 due to the magnetic field effect of the magnetic attraction members 300.

[0034] In certain embodiments, reference Figure 3 The top of the fixed mold base 100 is provided with a positioning slope 110, and the cavity 150 is provided at the bottom of the positioning slope 110. The positioning slope 110 can guide the workpiece when the workpiece is placed in the cavity 150, so that the workpiece can fall into the cavity 150 smoothly and accurately, thereby avoiding the problem of misalignment of the workpiece.

[0035] In certain embodiments, reference Figure 2The fixed mold base 100 has a plurality of cavities 150, and a plurality of magnetic parts 300 are distributed on the sides of each cavity 150, and the magnetic parts 300 corresponding to each cavity 150 have the same number and distribution. The plurality of cavities 150 can operate together, so that the effect of processing a plurality of workpieces simultaneously can be achieved, thereby effectively increasing the working efficiency. Since the number and distribution of the magnetic parts 300 corresponding to each cavity 150 are the same, the workpieces in each cavity 150 can be guided by the same magnetic field, and the misalignment problem in individual cavities 150 can be avoided.

[0036] It is conceivable that the magnetic field distribution at each cavity 150 may be different, so as to achieve the effect of processing different workpieces at one time. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0037] In certain embodiments, reference Figure 2 , the distances between the cavities 150 are equal. The cavities 150 with equal distances can make the magnetic field corresponding to each cavity 150 have the same influence on the other cavities 150, so as to avoid the influence of the non-corresponding magnetic field on the cavity 150 to the greatest extent, and thus make the automatic correction effect between the workpiece and the cavity 150 more accurate and effective.

[0038] In certain embodiments, reference Figure 3 , each cavity 150 is arranged in the middle of the fixed mold base 100 along the same straight line direction, and each magnetic attraction member 300 located on the same side of the cavity 150 has the same magnetic pole direction. One side of each cavity 150 is a magnetic attraction member 300 with the same magnetic pole direction, and the other side of each cavity 150 is a magnetic attraction member 300 with another magnetic pole direction. Therefore, the magnetic attraction member 300 can be arranged in an orderly manner under the division of the cavity 150, thereby ensuring that the magnetic field used to correct the workpiece can be formed more orderly and exert a more accurate magnetic field correction effect on the workpiece.

[0039] The second aspect of the utility model provides an embodiment of a molding mold, including the above correction system. The magnetic suction member 300 will form a directional magnetic field around the cavity 150, whereby, after the magnetic workpiece is placed in the cavity 150 manually or by a robot, the magnetic workpiece will be offset under the action of the magnetic field. Therefore, the direction and other states of the magnetic suction member 300 can be preset to determine the movement trajectory of the workpiece guided by the magnetic field, and then the magnetic field formed by the magnetic suction member 300 can be directly and effectively used to automatically guide the workpiece and the cavity 150, so that the workpiece can automatically achieve the correction effect with the cavity 150 after being placed in the cavity 150, and avoid the problem of damage to the mold and the workpiece due to misalignment of the workpiece.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
