Description

Technical Field

[0001] The present invention relates to the technical field of molds, and particularly relates to a rapid demolding device for an injection mold. Background Art

[0002] Injection molding is a common method for producing injection products, specifically referring to injecting the heat-melted material into the mold cavity under high pressure, and obtaining the formed product after cooling and solidification. During the injection molding process, in order to enable the product to fall off smoothly from the mold cavity after molding, an ejection mechanism is usually used to push out the product.

[0003] Among injection products, container products such as barrels, boxes, and cases with closed wall shells, bottoms, and cavity depths greater than five times the wall thickness are called deep cavity products. For example, the battery case: the wrapping force between the product and the mold core is large, and coupled with the adhesion and negative pressure effects, it is difficult to demold deep cavity products. After the ejection mechanism pushes the product out for a certain distance, auxiliary removal by staff is still required, which not only increases the labor intensity of the staff, but also the manual operation method of the staff is accompanied by certain operation risks.

By the sliding of the second moving electric slider 8 in the second moving chute 7, the second electric lifting rod 9 can be driven to move on the workbench 1.

[0041] As a technical optimization solution of the present invention, a first electric extension rod 24 is embedded inside the first mounting block 23. The extension end of the first electric extension rod 24 penetrates through the first mounting block 23 and extends to the outside of the first mounting block 23. A second rotating motor 33 is embedded on one side of the second mounting block 25 close to the first mounting block 23. The mounting end of the second rotating motor 33 faces the first mounting block 23.

The first electric extension rod 24 can drive the second mounting block 25 to extend. The second rotating motor 33 can drive the second mounting block 25 to rotate. The second electric extension rod 26 can drive the second connecting member 27 to move.

[0042] When the present invention is in use, the electrical devices used in the device are all powered by connecting to an external power source through wires. In the device, the electrical devices in the device are controlled by presetting a control system. Cameras are provided on one side of the second connecting block 12 and the second mounting block 25 facing the lower die 2 and the upper die 3. A camera is installed on the top of the workbench 1 at a position far from the lower die 2 and the upper die 3 through an electric telescopic lifting rod. By installing the camera, when the workpiece is ejected, the top surface and the surrounding surfaces of the workpiece can be photographed, and then the production quality of the workpiece and the usage conditions inside the upper die 3 and the lower die 2 can be judged by comparing with the standard picture. The lower die 2 and the upper die 3 are both existing mature technologies, so no more elaboration will be made on them. The workbench 1 is installed above the base of the injection molding machine. The top of the upper die 3 is connected to the top of the injection molding machine through a hydraulic rod, and its installation method is an existing mature technology, so no more elaboration will be made on it. Two blanking grooves 34 are opened on the workbench 1, one for blanking good products and the other for blanking defective products. A blanking conveyor belt is provided at the lower position of the blanking groove 34. The mold release agent nozzle 29 is connected to a preset mold release agent spraying device outside the device through a conduit, and the opening 32 is connected to a preset dust suction fan outside the device through a conduit, and the conduit has a sufficient length to ensure normal use during work.

[0043] After the workpiece is injection molded, the upper die 3 moves upward to a preset position, and the ejection mechanism in the lower die binds the workpiece upward to a preset use position. By sliding the first moving electric slider 5 in the first moving chute 4, the first connecting member 14 moves to a 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 member 14 to extend upward, and then the first electric telescopic rod 11 drives the first connecting member 14 to extend, so that the two first rotating blocks 15 abut against the outside of the workpiece. Subsequently, the first electric lifting rod 6 continuously drives the first connecting member 14 to extend upward until the workpiece is taken out from the inside of the lower die 2. By this operation method, the device can automatically take out the workpiece without manual operation by the staff and can complete the rapid demolding of the workpiece. The process of taking out the workpiece is as Figure 7 shown;

[0044] After the two first rotating blocks 15 clamp and take out the workpiece, by sliding the first moving electric slider 5 in the first moving chute 4, the two first rotating blocks 15 can clamp the workpiece to the blanking groove 34 for automatic blanking.

[0045] After the workpiece is demolded and blanked, when there is residual injection molding residue inside 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. By sliding the lifting electric slider 21 in the lifting chute 20, the brushing plate 22 moves out of the inside of the first slot 19. Subsequently, by extending the first connecting piece 14 driven by the first electric telescopic rod 11 and rotating the second connecting block 12 driven by the second rotating motor 18, the brushing plate 22 can enter the inside of the lower mold 2 and the upper mold 3, so as to complete the brushing of the injection molding residue inside the lower mold 2 and the upper mold 3, and can assist the injection molding residue to fall off between the upper mold 3 and the lower mold 2. The residue cleaning process is as Figure 8 shown;

[0046] The second rotating block 28 enters the position between the lower mold 2 and the upper mold 3 driven by the first electric extension rod 24 and the second electric lifting rod 9. Then, by moving the second connecting piece 27 driven by the second electric extension rod 26 and rotating 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 suction fan connected to the opening 32, and can complete the absorption of the injection molding residues between the lower mold 2 and the upper mold 3, so as to uniformly recycle the injection molding residues between the lower mold 2 and the upper mold 3, which is convenient for the recycling and reuse of the injection molding residue raw materials.

[0047] After the injection molding residues between the lower mold 2 and the upper mold 3 are cleaned, by rotating the second rotating block 28, the use position of the release agent nozzle 29 is adjusted, and the release agent spraying device connected to the release agent nozzle 29 is started. Combining the movement of the second rotating block 28 between the lower mold 2 and the upper mold 3, the automatic spraying of the release agent between the lower mold 2 and the upper mold 3 can be completed, increasing the use convenience of the device.

[0048] When it is necessary to detect the precision between the upper mold 3 and the lower mold 2, the first rotating block 15 rotates to make the laser distance sensor 16 face the lower mold 2 and the upper mold 3. Subsequently, by moving up and down through the first connecting piece 14, the laser distance 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 comparison difference exceeds the standard difference range, it indicates that there is an installation deviation between the upper mold 3 and the lower mold 2. At this time, the staff can repair the upper mold 3 and the lower mold 2 according to the detection result.

[0049] By means of the camera set in this device, when the workpiece is injection molded and ejected by the ejection mechanism in the lower mold 2, 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 and convex abnormal conditions on the surface of the workpiece,

[0050] The conditions for specific judgment are as follows:

[0051] If D(x, y) is greater than T (threshold), there is an abnormal concavity or convexity at the point (x, y). If D(x, y) is less than or equal to T (threshold), it is normal at the point (x, y).

[0052] Statistically calculate the proportion of abnormal points in the entire picture of the captured image. If it exceeds the threshold P%, it is determined that the surface of the workpiece is unqualified. The five outer surfaces of the workpiece are photographed through a camera (including the top and the four sides of the workpiece). If any one of the five surfaces is unqualified, it means that the workpiece is unqualified. It is mainly used to detect whether there are any protrusions or depressions on the outer surface of the prepared workpiece that are different from the standard workpiece.

[0053] The meaning of Istd(x, y) is the pixel intensity of the standard image at (x, y), and its acquisition method is to directly read the grayscale image through a camera. The meaning of Itest(x, y) is the pixel intensity of the captured image at (x, y), and its acquisition method is to directly read the grayscale image through a camera. The meaning of is the gradient (edge intensity) of the image, and its acquisition method is to calculate through the sobel / prewitt algorithm. This algorithm is a mature existing technology, so it will not be elaborated too much here. The meaning of λ is the weight coefficient of the gradient difference, and its acquisition method is to adjust through experimental data. The meaning of T is the single-point difference threshold, and its acquisition method is to determine through statistical normal samples. The meaning of P% is the allowable proportion of abnormal points, and its acquisition method is set according to specific production requirements.

[0054] When the surface of the workpiece is detected to be normal, the device discharges the workpiece from the good product discharge chute 34. When an abnormality is detected in the captured image, the device discharges the workpiece from the defective product discharge chute 34. Through this operation method, the classification and discharging of good and defective products of the workpieces produced by the device can be completed.

[0055] And when an abnormality of the workpiece is detected, the device takes the above cleaning steps to complete the cleaning of the inside of the upper die 3 and the lower die 2. After the cleaning of the upper die 3 and the lower die 2 is completed, the production of the workpiece continues. Then, the workpiece after cleaning the upper die 3 and the lower die 2 is detected. If the workpiece after the device cleaning does not have the concavity and convexity problems generated on the previous workpiece, then it can be determined that there are impurities inside the upper die 3 and the lower die 2 that affect the production quality of the workpiece, and the device can quickly solve this problem through self-cleaning, ensuring the production rate of the device for the workpiece. If the workpiece produced after the cleaning of the upper die 3 and the lower die 2 still has concavity and convexity problems, then it means that there are problems with the upper die 3 and the lower die 2. At this time, it prompts the staff to quickly repair the upper die 3 and the lower die 2 to prevent the device from producing a large number of defective workpieces.

[0056] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
