The utility model relates to a quick ejection die of front and back moulds even slanting extraction, including upper panel, front mould panel, back mould panel, mould foot, lower panel and ejection mechanism, be provided with the injection port of injection chamber as injection moulding mouth on the upper panel fixedly, install the elastic member between the upper panel and front mould panel, be provided with the damping open -close ware connection between the front mould panel and back mould panel, be provided with front mould slanting extraction subassembly on the injection bush, front mould slanting extraction subassembly includes the front mould slanting extraction piece, the oblique hole containing front mould slanting extraction piece is set up on the front mould kernel and passes through, front mould slanting extraction piece is moved in the oblique hole under the injection bush pull. Adopt above -mentioned technical scheme, the utility model through setting up elastic member and damping open -close ware between front mould and upper panel, make upper panel first in front mould action when opening mould action, thus fixed on upper panel drive injection bush upper setting mould slanting extraction subassembly first in front mould action core pulling, make its safe separation product Z direction's reverse buckle position.

This invention discloses a thrombus filter that is easy to fix and safely remove, relating to the field of medical device technology. The thrombus filter includes a filter screen made of metal wire and a retrieval hook at its proximal end. After the filter screen is released, both the distal and proximal ends have circumferentially evenly distributed petal-shaped mesh openings, the mesh size of which is smaller than that of the middle section mesh opening, and the mesh openings at both ends are staggered circumferentially. Multiple auxiliary positioning structures are provided at the maximum diameter of the filter screen. These structures include a positioning retaining ring and positioning spikes connected by biodegradable bioadhesive. These provide stable anchoring during initial implantation, and after the bioadhesive degrades, allow the positioning spikes and retaining ring to move relative to each other or separate, achieving minimally invasive removal. This invention balances reliable fixation during initial implantation with operational safety during removal, and also has a more significant thrombus-blocking effect.

The utility model provides a lifting device for a track inspection robot, which comprises a movable framework arranged between steel rails, a lifting unit arranged at the bottom of the movable framework and used for driving the movable framework to fall to the ground or be suspended, and an opening and closing unit arranged at the top of the movable framework and used for being clamped with or separated from the steel rails. The lifting unit and the opening and closing unit are both connected with the central control unit, and the opening and closing unit comprises a first anti-rollover rail wheel rolling along the outer side wall of a steel rail and a second anti-rollover rail wheel rolling along the inner side wall and the top face of the steel rail. When the robot detects that a bullet train approaches, a derailment program is triggered immediately, and the track inspection robot is rapidly fixed at a safe position in the middle of a track through the device, so that the inspection robot can be safely, accurately and rapidly separated from the track when detecting that the bullet train approaches, the potential collision risk is avoided, the detection efficiency is improved, and detection can be performed in any time period; and the method does not depend on window period operation.
