Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a quick demolding device for injection molds. Background Technology

[0002] Injection molding is a common method for producing injection-molded products. Specifically, it involves injecting molten material under high pressure into a mold cavity, where it cools and solidifies to obtain the molded product. During the injection molding process, an ejector mechanism is typically used to push the product out of the mold cavity after molding.

[0003] In injection molding, containers such as barrels, boxes, and cartons with enclosed shells, bottoms, and cavities whose depth is more than five times the wall thickness are called deep-cavity products, such as battery casings. The strong encapsulation force between the product and the mold core, coupled with adhesion and negative pressure, makes demolding deep-cavity products difficult. After the ejection mechanism pushes the product out a certain distance, workers are required to remove it, which not only increases the labor intensity of the workers, but also carries certain operational risks due to the manual operation.

[0043] After the workpiece is injection molded, the upper die 3 moves upward to the preset position, the ejection mechanism in the lower die 2 ejects the workpiece upward to the preset use position, the first moving electric sliding block 5 slides in the first moving sliding groove 4, the first connecting piece 14 moves to the preset use position on one side of the lower die 2 and the upper die 3, the first electric lifting rod 6 drives the first connecting piece 14 to extend upward, then the first electric telescopic rod 11 drives the first connecting piece 14 to extend, so that the two first rotating blocks 15 abut to the outside of the workpiece, then the first electric lifting rod 6 continuously drives the first connecting piece 14 to extend upward, until the workpiece is taken out from the inside of the lower die 2, through this operation mode, the device can automatically take out the workpiece without manual operation of the worker, and the rapid demolding of the workpiece can be completed. Figure 7

[0044] After the two first rotating blocks 15 clamp and take out the workpiece, the first moving electric sliding block 5 slides in the first moving sliding groove 4, so that the two first rotating blocks 15 can clamp the workpiece to the discharge groove 34 for automatic discharging.

[0045] ​When the workpiece demolding and blanking is completed, and the injection molding residues are left in the lower mold 2 and the upper mold 3, at this time, the first rotating block 15 moves to the position between the lower mold 2 and the upper mold 3, and through the sliding of the lifting electric sliding block 21 in the lifting sliding groove 20, the brushing plate 22 moves out of the inside of the first slot 19, and then through the extension of the first electric telescopic rod 11 driving the first connecting piece 14 and the rotation of the second rotating motor 18 driving the second connecting block 12, the brushing plate 22 can enter the inside of the lower mold 2 and the upper mold 3, so that the brushing of the injection molding residues in the lower mold 2 and the upper mold 3 can be completed, which can assist the injection molding residues to fall off between the upper mold 3 and the lower mold 2. The residue cleaning process is as shown in Figure 8

[0046] The second rotating block 28 enters the position between the lower mold 2 and the upper mold 3 under the driving of the first electric extension rod 24 and the second electric lifting rod 9, and then through the movement of the second connecting piece 27 driven by the second electric extension rod 26 and the rotation of the second mounting block 25 driven by the second rotating motor 33, the second rotating block 28 can move between the lower mold 2 and the upper mold 3 to start the dust collection fan connected by the opening 32, so that the injection molding residues between the lower mold 2 and the upper mold 3 can be absorbed, thereby the injection molding residues between the lower mold 2 and the upper mold 3 can be uniformly recycled, which is convenient for recycling and reusing of the injection molding residues raw materials.

[0047] After the injection molding residues between the lower mold 2 and the upper mold 3 are cleaned, the use position of the demolding agent nozzle 29 is adjusted through the rotation of the second rotating block 28, the demolding agent spraying equipment connected by the demolding agent nozzle 29 is started, and combined with the movement of the second rotating block 28 in the lower mold 2 and the upper mold 3, the automatic spraying of the demolding agent between the lower mold 2 and the upper mold 3 can be completed, which increases the use convenience of the device.

[0048] When the precision between the upper mold 3 and the lower mold 2 needs to be detected, the first rotating block 15 rotates so that the laser ranging sensor 16 faces the lower mold 2 and the upper mold 3, and then through the lifting movement of the first connecting piece 14, the laser ranging sensor 16 can complete the distance detection between the upper mold 3 and the lower mold 2, and transmit the measured data value to the background control system for comparison. If the difference value exceeds the standard difference value range, it means that there is an installation deviation between the upper mold 3 and the lower mold 2, at this time, the workers can repair the upper mold 3 and the lower mold 2 according to the detection results.

[0049] Through the camera provided in the device, when the workpiece is ejected by the ejection mechanism in the lower mold 2 after the workpiece is injection molded, the surface of the workpiece is photographed by the camera, and the photographed pictures are calculated and compared according to the following formula, so as to judge the concave-convex abnormality of the workpiece surface,

[0050] ​The specific judgment condition is:

[0051] If D(x, y) is greater than T (threshold value), there is a concave-convex anomaly at the point (x, y), and if D(x, y) is less than or equal to T (threshold value), the point (x, y) is normal.

[0052] The proportion of abnormal points in the entire picture is counted, and if it exceeds the threshold P%, the workpiece surface is determined to be unqualified. By shooting the five surfaces of the workpiece (including the top and the periphery of the workpiece) through the camera, if any one of the five surfaces is unqualified, it means that the workpiece is unqualified. It is mainly used to detect whether the prepared workpiece surface has protrusions or depressions different from the standard workpiece.

[0053] Where Istd(x, y) means the pixel intensity of the standard picture at (x, y), which is obtained by directly reading the gray scale through the camera, and Itest(x, y) means the pixel intensity of the shooting picture at (x, y), which is obtained by directly reading the gray scale through the camera, The meaning of is the gradient (edge intensity) of the image, which is calculated by the sobel / prewitt algorithm, which is a mature technology, so it will not be described in more detail, the meaning of λ is the weight coefficient of the gradient difference, which is adjusted by experimental data, the meaning of T is the single-point difference threshold, which is determined by statistical normal samples, and the meaning of P% is the allowed proportion of abnormal points, which is set according to the specific production requirements.

[0054] When the workpiece surface is normal, the device discharges the workpiece from the good product discharge chute 34, and when the shooting picture has an abnormality, the device discharges the workpiece from the substandard product discharge chute 34, so that the good and substandard products of the device can be classified and discharged;

[0055] And when the workpiece is abnormal, the device takes the above cleaning steps to clean the inside of the upper die 3 and the lower die 2, and continues to produce the workpiece after cleaning the upper die 3 and the lower die 2, and then detects the workpiece after cleaning the upper die 3 and the lower die 2. If the workpiece after cleaning by the device does not have the concave-convex problem produced by the previous workpiece, it can be determined that there is impurity in the inside of the upper die 3 and the lower die 2 affecting the production quality of the workpiece, and the device can quickly solve the problem by self-cleaning, ensuring the production rate of the device. If the workpiece produced after cleaning the upper die 3 and the lower die 2 still has the concave-convex problem, it means that the upper die 3 and the lower die 2 have a problem, so the worker is prompted to quickly repair the upper die 3 and the lower die 2 to prevent the device from producing a large number of substandard workpieces.

[0056] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
