4results about How to "Avoid drawing phenomenon" patented technology

This invention relates to the field of adhesive coating technology and discloses an adhesive coating device for an induction cooker panel, including a base, a linear guide rail on the base, a spray gun fixedly mounted on the linear guide rail, the spray gun including an adhesive supply pipe and a movable nozzle, a back suction valve on the adhesive supply pipe, a fixed pipe connecting the adhesive supply pipe and the movable nozzle, the fixed pipe being fixedly connected to the linear guide rail, a limit cylinder coaxially fixedly mounted on the fixed pipe, the movable nozzle coaxially mounted inside the limit cylinder and connected to the fixed pipe through a cylindrical elastic membrane, a magnet fixedly mounted on the movable nozzle, and a winding coaxially mounted on the limit cylinder; this application achieves rapid stretching and breaking of the adhesive by driving the movable nozzle to rotate circumferentially and causing the elastic membrane to undergo helical torsional deformation, forming an axial tensile force that drives the movable nozzle to move axially, thereby achieving rapid stretching of the adhesive and breaking it. At the same time, combined with the back suction effect of the back suction valve and the pressure-holding design of the elastic membrane, it effectively solves the problem of easy stringing of the adhesive at the end of the coating process.

The utility model relates to the technical field of glue dispensing, in particular to a multifunctional glue dispensing machine, and provides the following scheme aiming at the problems that the wire drawing phenomenon occurs during glue dispensing, the glue dispensing effect is greatly influenced, the thickness of a glue dispensing area is not uniform and the practicability is influenced due to the fact that part of existing glue dispensing machines cannot effectively process outlets of glue guns. The table comprises a table body; the supporting column is arranged on the ground, a plurality of first sliding grooves are formed in the table body, a table top is fixedly installed on the table body, a cutting table is connected to the first sliding grooves in a sliding mode, a transmission box is fixedly installed on the table body, a machine box is fixedly installed on the transmission box, and a plurality of fixing blocks are fixedly installed on the table body. And the cutting knife is driven to move left and right to cut the glue at the outlet of the glue gun, so that the glue is disconnected, the wire drawing phenomenon is avoided, and the glue dispensing uniformity and effect can be effectively improved.

The utility model relates to injection mold technical field, and disclose a kind of plastic mold gate bushing anti-wire drawing structure, including gate bushing body, the upper end of gate bushing body is drop-like, the center area of gate bushing body is formed with the tapering material delivery port, the upper end of gate bushing body is equipped with chamber, the inside of chamber is slidably connected with cutoff plate, and one end of cutoff plate is in contact with the inner wall of chamber.This kind of plastic mold gate bushing anti-wire drawing structure, through the slot hole set on cutoff plate, nozzle can pass through slot hole to the raw material in material delivery port, and the cutoff plate set can be after raw material delivery is completed, cutoff plate will raw material of material delivery port cut off, prevent the appearance of wire drawing phenomenon, not only effectively avoid the surface flaw of the forming piece caused by wire drawing, improve the appearance quality of product, and cutting action is rapid and accurate, can maximum degree reduce the waste of raw material in cutting process, reduce production cost.

The invention relates to the technical field of mold manufacturing, and provides a router shell injection mold which comprises a bottom plate parallel to the ground; the two supporting plates are installed on the front side and the rear side of the bottom plate correspondingly and comprise the front supporting plate and the rear supporting plate. The injection molding device is mounted at the front part of the front support plate; the static template is fixedly mounted at the rear part of the front support plate, and a movable template is arranged at the rear part of the static template; the injection port is formed in the middle of the front support plate, one end of the injection port is communicated with an inner cavity of the static template, and the other end of the injection port is communicated with a discharge port of the injection molding device; the sliding groove is formed in the front middle part of the top end of the front supporting plate, and the injection port is vertically separated by the sliding groove; and the injection port is vertically divided into a front hot melting port and a rear cooling port by a sliding groove. When the injection mold is used, the injection port is separated, the phenomenon of wire drawing during demolding caused by temperature difference between cooled plastic in the mold cavity and hot melting plastic at the injection port is avoided, residual plastic at the injection port is cleaned and utilized, and material loss is reduced.
