This invention discloses a raw material mixing tank for processing work gloves, relating to the field of work gloves. It includes an exhaust device mounted on the top of the tank exterior; a sleeve coaxially fixedly mounted on the top of the tank interior, with at least one atomizing nozzle fixedly mounted circumferentially on the outer wall of the sleeve; a drive shaft coaxially disposed within the tank interior; a bushing coaxially and vertically slidingly fitted onto the outer side of the drive shaft, with a helical blade coaxially fixedly connected to the outer wall of the bushing; at least one vertical side scraper disposed on the outer side of the bushing and fixedly connected to the drive shaft via a support rod; and a bottom scraper mounted at the bottom end of the drive shaft, abutting against the bottom surface of the tank interior. The beneficial effects of this invention are: the helical blades, with their coordinated undulating and rotating motion within the tank, combined with the wall and bottom scraping structures, along with the exhaust device and the physical-chemical nozzle, achieve three-dimensional convection of the raw materials, improving mixing uniformity, eliminating dead zones, suppressing agglomeration and eliminating air bubbles, thereby improving batching efficiency and glove qualification rate.

The invention belongs to the technical field of die-casting dies, and provides a die-casting die for a shell, which comprises a movable die assembly, a fixed die assembly, a sliding block mechanism, a cooling mechanism and a feeding mechanism, the sliding block mechanism comprises an auxiliary sliding block, and the auxiliary sliding block comprises a feeding end face and a profiling face. The fixed mold assembly comprises a mold core, and a cooling hole is formed in the mold core; the cooling mechanism comprises a high-pressure point cooling pipe, and the high-pressure point cooling pipe is used for forming a cooling loop in the sleeve; the feeding mechanism comprises a main flow channel and a feeding channel. Compared with the prior art, the auxiliary sliding block is arranged on the side wall, without an inverted buckle structure, of the product cavity to serve as a feeding auxiliary structure, the feeding direction of the product cavity is parallel to the thickness direction of the shell in cooperation with the feeding mechanism, stable feeding of molten metal in the thickness direction of the shell is achieved, and strong impact on local parts of the cavity is avoided; and the filling uniformity of the molten metal is improved.

The invention relates to equipment and a method for tamping furnace charge outside a furnace, and belongs to the technical field of alloy production equipment and methods. According to the technical scheme, a reaction furnace body (12) is arranged below a steel frame (4), and a moving assembly (1) is arranged above the steel frame (4); the moving assembly (1) comprises a tamping assembly, a moving steel frame, moving wheels and a scraper assembly, the tamping assembly and the scraper assembly are installed on the moving steel frame, and the moving steel frame moves through the moving wheels; the input end of the piston type vibrator (2) is connected with the two-port gas storage tank (5), and the output end is connected with the tamping assembly; and the electrical cabinet (3) is connected with the moving assembly (1) and the piston type vibrator (2). The device has the beneficial effects that the tamping air cylinder is adopted to drive the tamping plate to compress the furnace charge, and the pneumatic vibrator is started to further vibrate and compact the furnace charge, so that the thermit reaction is stable, gas among furnace charge particles is reduced, and the defect that air holes are generated in alloy is avoided.
