The invention discloses an EPP seat foaming die and a foaming technology. The EPP seat foaming die comprises an upper template and a lower template. An upper die core is arranged in the upper template, and a lower die core is arranged in the lower template. A plurality of positioning blind holes are formed in the edge position of the lower surface of the upper die core. Magnetic inserts are embedded in the positioning blind holes. A framework steel wire is adsorbed to the bottom of each magnetic insert. The adjacent framework steel wires are connected in an end-to-end manner, and the shape matched with the outer edge of a seat product is defined by all the framework steel wires. According to the foaming technology, the magnetic inserts are embedded in the corresponding positioning blind holes in the upper template, the framework steel wires connected in the end-to-end manner are stably adsorbed to the bottoms of the magnetic inserts, the upper template and the lower template are assembled and combined into the foaming die, and after EPP foam particles are subjected to pressure loading, the EPP foam particles are injected into the die through a spray gun to be formed. Through the foaming technology and the foaming die matched with the foaming technology, the EPP raw materials and the framework steel wires can be integrally formed, the strength of the edge of a formed seat body is improved, and accordingly staggering of the pressurized seat and a seat cover is avoided.

The invention provides a chemical vapor deposition furnace. The furnace comprises a furnace body; an upper furnace cover which is arranged at the upper portion of the furnace body and is detachably fixedly connected with the furnace body in a sealing manner; a lower furnace cover arranged at the lower portion of the furnace body and in sealed detachable fixed connection with the furnace body; and a lower furnace cover elevating mechanism fixedly connected with the lower furnace cover to make the lower furnace body removed from the fixed furnace body drive the lower furnace cover to fall in order to discharge and drive the lower furnace cover after discharge to rise to be combined with the furnace body. The chemical vapor deposition furnace also comprises a forward / backward pushing mechanism arranged just below the lower furnace cover, and the forward / backward pushing mechanism makes the lower furnace cover elevating mechanism drive the falling lower furnace cover to fall on the forward / backward pushing mechanism and forward / backward move to the periphery in order to carry out discharging and charging. The furnace body, the upper furnace cover and the lower furnace cover adopts a water cooling interlayer and a heat insulating layer respectively. The mutual dislocation of the furnace body in the repeated dismounting process is avoided; the discharging and the charging are safe and reliable, and are convenient to operate; and the stability of the thermal field in the furnace is stable, and the high temperature work safety is improved.

The invention discloses a reinforcing rib making die for a ribbed superposed concrete prefabricated member. The die comprises a first template and a second template which are arranged corresponding to each other; the sections of the first template and the second template respectively consist of a vertical plate body and a horizontal plate body positioned at the lower part of the vertical plate body and are L-shaped; a first elastic lining film and a second elastic lining film are respectively arranged on the inside walls of the first template and the second template; the mutually corresponding edges of the first lower lining film and the second lower lining film are respectively concave-convex; a first baffle plate and a second baffle plate are respectively arranged between the first template and the second template and are respectively in contact with the first elastic lining film and the second elastic lining film; the first baffle plate is provided with a first steel bar hole and asecond steel bar hole; and the second baffle plate is provided with a third steel bar hole and a fourth steel bar hole. The die has the remarkable characteristics of standardization, strong interchangeability, simplicity and convenience in disassembly and assembly, no need of die release treatment and capability of meeting industrialized production of concrete prefabricated members.

The invention discloses an assembled geocell which comprises a first geocell body, a second geocell body, a third geocell body and a fourth geocell body, and the first geocell body, the second geocell body, the third geocell body and the fourth geocell body are the same and / or different in shape and size. Movable rods are moved out of rotating sleeves through rotating the rotating sleeves and the spiral effect of the rotating sleeves and the movable rods till the ends of the movable rods of the two connecting devices make contact with each other, the joint of the two movable rods can be sleeved with a rubber sleeve, the ends of the two movable rods are prevented from being staggered, and the rotating sleeves continue to be rotated; the distance between the two connecting devices is limited by utilizing the extending lengths of the two movable rods, and the volumes of the first geocell body, the second geocell body, the third geocell body, the fourth geocell body and the central space of the four geocell bodies are further changed under the cooperation of a second nut, a first frame plate and a second frame plate. The whole geocell can meet the building requirements of different working conditions, and the whole geocell is convenient to install.
