Description

Technical Field

[0001] The utility model relates to the technical field of LED bracket mold demoulding, in particular to an LED bracket mold demoulding device. Background Art

[0002] The traditional production process of LED brackets includes stamping, electroplating, injection molding, cutting and packaging. Among them, LED brackets need molds when they are injected, so injection molding is also called injection molds. Injection molds are a major molding method for thermoplastic plastic parts, and can successfully inject certain thermosetting plastics. After injection molding and cooling, the LED bracket needs to be demolded to obtain the finished product;

[0003] The existing patent number CN202122347223.3 discloses an LED bracket mold, which drives the frame to move up and down by a hydraulic rod to adjust the height position of the frame, and debugs the stamping cylinder to drive the upper mold and the upper module to perform stamping operation. After debugging, the LED bracket is placed in the lower mold groove above the lower mold, and then the upper mold is driven downward by the stamping cylinder, so that the upper mold and the lower mold are molded together, thereby realizing the stamping and pressing of the LED bracket; after the stamping is completed, the stamping cylinder recycles the upper mold, and at the same time, the ejection cylinder inside the lower mold generates a reaction force after being stamped, pushing the piston rod to move upward, pushing the ejection plate, the first ejection rod and the second ejection rod through the ejection through hole on the lower mold to eject the LED bracket from the lower mold; the LED bracket and the lower mold are separated, which is very practical.

[0004] However, when the ejector plate of the LED bracket mold ejects the LED bracket mold, it is easy to cause the LED bracket to deform due to the adhesion of the side and the molding groove, thereby reducing the production efficiency; therefore, it does not meet the existing needs. In this regard, we propose an LED bracket mold demolding device. Utility Model Content

[0005] The purpose of the utility model is to provide an LED bracket mold demolding device to solve the problem that when the ejection plate of the LED bracket mold proposed in the above background technology ejects the LED bracket mold, it is easy to cause the LED bracket to deform due to the adhesion of the side and the molding groove, thereby reducing the production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a LED bracket mold demolding device, comprising a lower mold and a base, a mold groove is opened inside the upper end of the lower mold, a driving groove is opened at the bottom end of the base, the interior of the driving groove is connected to a support plate through cylinder drive, one side of the upper end of the support plate is fixedly connected to a guide rod that movably penetrates the top of the base and is fixedly connected to the bottom end of the lower mold, a shaping block that penetrates the lower mold and extends to the inside of the mold groove is fixedly connected to the middle of the top end of the base, a groove is opened inside the top of the shaping block, and a top block is movably connected inside the groove.

[0007] Preferably, a slide groove is provided at the upper end of the support plate away from the guide rod, a slider is slidably connected inside the slide groove, and a limit rod is fixedly connected to one side of the bottom end of the shaping block in an inclined manner.

[0011] Preferably, the upper end of the sliding block on one side close to the guide rod is arranged in an inclined surface, and the bottom end of the connecting rod movably extends through the inside of the driving groove and contacts with the inclined surface of the sliding block.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model starts the cylinder to drive the support plate to move upward, and at this time, the lower mold is lifted up from the upper end of the base along the shaping block through the connection between the guide rod and the lower mold, thereby preventing the bottom end of the LED bracket mold from sticking to the outside of the shaping block, and driving the slider to move along the outer surface of the limit rod while the support plate moves up, thereby driving the slider to move along the slide groove toward one side of the connecting rod, and when the inclined surface on one side of the slider contacts the bottom end of the connecting rod, the connecting rod is pushed to move along the inclined surface of the slider toward the top end extending through the shaping block, and the spring is squeezed and compressed through the limit block.

[0020] A slide groove 8 is provided on the upper end of the side of the support plate 6 away from the guide rod 7, and a slider 9 is slidably connected inside the slide groove 8. A limit rod 10 is fixedly connected to one side of the bottom end of the shaping block 11. A through groove connected to the slide groove 8 is provided on one side of the bottom end of the support plate 6. One end of the limit rod 10 away from the shaping block 11 moves through the slider 9 and extends to the inside of the through groove. When the support plate 6 moves upward, the slider 9 is driven to move along the surface of the limit rod 10, and then the slider 9 is driven to move along the slide groove 8 toward one side of the connecting rod 13. When the inclined surface on one side of the slider 9 contacts the bottom end of the connecting rod 13, the connecting rod 13 is pushed to move along the inclined surface of the slider 9 toward the top of the shaping block 11.

[0021] A pushing groove 12 is provided in the middle of the top of the base 2 and extends to the bottom end of the shaping block 11.
