The utility model discloses a hot runner, mould, wherein hot runner contains hot runner body and the glue inlet, and the glue inlet is located on hot runner body, and is linked with the injection molding machine nozzle of outside, still contains: bottle embryo injection nozzle, bottle embryo injection nozzle is linked with the bottom of the bottle embryo cavity of outside's glue inlet intercommunication, and bottle embryo injection nozzle conveys injection molding material to bottle embryo cavity, handle injection nozzle, handle injection nozzle is linked with the bottom of the handle cavity of outside's glue inlet intercommunication, and handle injection nozzle conveys injection molding material to handle cavity. The utility model discloses through adding a handle nozzle, realizes handle single injection molding, is not affected by bottle embryo injection molding, can shorten injection molding time, guarantees the heat of bottle embryo to blow -molding qualified handle bottle.

The application relates to the technical field of batteries, in particular to a battery cell cover plate and a battery cell. The battery cell cover plate comprises: a liquid injection hole arranged on a cover plate main body; a first insulating piece with a first cavity and a second cavity arranged at intervals along the thickness direction of the cover plate main body; the opening of the first cavity faces the cover plate main body, the opening of the second cavity faces away from the cover plate main body, the cavity bottom of the second cavity is provided with a first through part in communication with the first cavity, and the side wall of the second cavity is provided with a second through part in communication with a pole group; a sealing cover piece is connected with the first insulating piece, the sealing cover piece seals the opening of the second cavity and can abut against the pole group, the application realizes smooth inflow of electrolyte, improves the stability of the battery cell in the process of high-temperature baking and pre-charging, the sealing cover can increase the contact area of the battery cell cover plate and the pole group, the pole group is more safe and stable in the battery cell and is not prone to shaking, and therefore the performance and safety performance of the battery cell are ensured.

This utility model discloses a clamping and sealing device, relating to the field of microfluidic chip injection technology. The clamping and sealing device includes: a frame; a placement seat mounted on the frame, having a placement position for placing the microfluidic chip; and an opening and closing module mounted on the frame, comprising a driving component and an opening and closing component. The opening and closing component has a first position and a second position relative to the placement position. The driving component can drive the opening and closing component to reciprocate between the first and second positions. When the opening and closing component is in the first position, it presses against the irregularly shaped structure to block and close the first channel. When in the second position, the opening and closing component moves away from the irregularly shaped structure to allow the first channel to open. The technical solution provided by this utility model can solve the problem of inconvenient and rapid injection of microfluidic chips in existing systems.

Some embodiments of the present application provide an injection mold, comprising: an outer slider reciprocating along a first horizontal direction, a through hole inclined to the first horizontal direction being formed on the outer slider; an inner slider slidingly arranged on the outer slider and having a limiting position; a slanted ejector pin penetrating the through hole and rotatably connected to the inner slider at one end to swing relative to the inner slider in a second horizontal direction to have a molding position and a demolding position, the other end of the slanted ejector pin cooperating with the outer slider to form a molding cavity capable of molding a reverse locking structure when being at the molding position, the second horizontal direction being perpendicular to the first horizontal direction; and a driving assembly comprising a driving member and a limiting member, the driving member being configured to drive the outer slider to move, and the limiting member being configured to limit the inner slider at the limiting position when the outer slider drives the slanted ejector pin to swing between the molding position and the demolding position. The outer slider drives the slanted ejector pin to swing to realize demolding, without the need to set a slanted guide pillar to drive the slanted ejector pin, which is conducive to the miniaturization design of the mold and reduces the cost.
