This utility model provides an in-mold hot-cutting device for injection molding machines, including a fixed mounting plate and an injection mounting plate. The fixed mounting plate is connected to a mold parting assembly and has a push groove. The mold parting assembly is connected to a mold component, which includes a mold assembly and an injection assembly. The injection assembly includes an injection mounting plate, which is rotatably connected to an injection mold plate. A hot-cutting lever is inserted into the side of the injection mounting plate. By causing the injection mounting plate and the injection mold plate to rotate relative to each other, the injection gate is cut off, realizing in-mold hot-cutting technology. This separates the injection-molded model from the injection runner. The central mold parting rod can push out the injection runner, and the mold parting push rod can push out the injection-molded product. This reduces the steps required to separate the runner after injection molding, simplifies the workflow, improves injection efficiency, does not affect the product appearance quality, and significantly reduces the product scrap rate.

The invention belongs to the field of cables, and provides a high-voltage cable insulation eccentricity quality detection method and a deviation adjusting tool, and the method comprises the steps: S1, drawing an inner identification line at the outer side of a semi-conductive wrapping tape; s2, intercepting a detection sample section; s3, drawing a main outer identification line and an auxiliary outer identification line in the axis direction of the detection sample section; s4, cutting a plurality of test pieces, and insulating the thinnest point position and the thickest point position; and S5, observing the orientation distribution of the thinnest point and the thickest point of each test piece. Compared with the prior art, the method has the advantages that the inner marking line is applied before the conductor enters the three-layer co-extrusion machine head, the main / auxiliary outer marking line with the space direction definition is established on the surface of the take-up sample section, and multi-point slicing detection and space direction reduction are combined, so that the appearance quality of a certified cable is not influenced, and meanwhile, the production efficiency is improved. And reasons causing poor insulation eccentricity can be visually distinguished, so that an adaptive deviation adjusting mode can be selected according to the actual eccentricity condition, and accurate positioning of the real insulation eccentricity position and accurate judgment of causes are guaranteed.

This invention relates to the field of office and teaching equipment technology, and particularly to a writing board and its installation method. The writing board includes a fixed plate and a movable plate, the movable plate being combined with the fixed plate via a sliding mechanism to form the writing board. The sliding mechanism includes at least two guide rails and at least one connector, the guide rails being connected by the connector to form a split-type combinable guide rail. The two ends of the split-type combinable guide rail and the connector are fixedly installed, and the split-type combinable guide rail is located behind the fixed plate and the movable plate. The movable plate can slide along the split-type combinable guide rail. This writing board solves the logistical, handling, and installation problems caused by excessively long borders, reduces noise, has a more concise and aesthetically pleasing overall design, and improves the user experience.

The application discloses a rapid pipeline pressure sealing device and a sealing method, and is applied to an oil and gas pipeline with strip crack leakage or point leakage; a hollow cylindrical cover body is arranged on a leakage position of the oil and gas pipeline, a closed leakage cavity is formed between the middle part of the hollow cylindrical cover body and the oil and gas pipeline; the hollow cylindrical cover body is spliced by two arc cover plates, connecting edges are arranged at the abutting positions of the two arc cover plates, the abutting surfaces of the two connecting edges are sealing planes, and the two abutting connecting edges form a strip-shaped structure; end face covers are fixed at two ends of the hollow cylindrical cover body, limiting squares are arranged on the end face covers, and the strip-shaped structure is arranged in the limiting squares; a sealing flow channel is arranged at the joint surface of the end face cover and the hollow cylindrical cover body, and the sealing flow channel is formed by the end face cover, the hollow cylindrical cover body and the oil and gas pipeline; oil-resistant sealing glue is injected into the sealing flow channel to form a sealing structure; and a pressure relief structure is connected to one of the arc cover plates of the hollow cylindrical cover body and is communicated with the leakage cavity. The application is suitable for pipeline sealing operation of pipelines with different flatnesses and can rapidly realize sealing operation of the pipeline with strip crack leakage.
