The casting mold comprises a machining table and a machining cover, the machining cover is arranged at the top of the machining table, a lead screw is arranged on one side of an open groove in the machining table, a transmission block is arranged on the lead screw, a sliding rod is arranged on the other side of the open groove in the machining table and parallel to the position of the lead screw, and the transmission block is arranged on the sliding rod. A sliding block is arranged at the position, corresponding to the transmission block, of the sliding rod, the top of the sliding block and the top of the transmission block are fixedly connected with a lower mold through open grooves, telescopic rods are arranged on the two sides of the bottom of the lower mold correspondingly, and the output ends of the telescopic rods extend into a mold groove of the lower mold to be fixedly connected with a top plate; and the top of the top plate is fixedly connected with a mold cavity. By moving the lower die, material taking is convenient, the labor intensity can be reduced, secondary cooling can be conducted on the lower die before material taking, high-temperature scalding is prevented, and dropped metal liquid can be received and prevented from dropping on the surface of a workpiece.

This utility model relates to the field of welding auxiliary equipment technology and discloses an anti-splash device for welding aluminum alloy pipes, including a base and a protective cover. A top frame is fixedly installed on the top of the base, and a lifting mechanism is fixedly installed inside the top frame. The movable end of the lifting mechanism is fixedly connected to the protective cover. This utility model utilizes the lifting mechanism to lower the protective cover and place it over the outside of the pipe to be welded, achieving surround protection above the welding area. Manual welding operations can be performed along both sides. During welding, a suction pump draws the welding area along the filter collection section, suction pipe, and suction port. The suction forcefully draws in and filters the tiny splashed metal particles into the filter collection section, ensuring welding operation space on both sides while achieving the separation and collection of splashed metal particles, avoiding high-temperature burns from splashing, and preventing splashed metal particles from falling into the welding area and affecting the welding process. The overall protective effect is good.

The present invention discloses a workbench for thermocouple thermal resistance testing, comprising a component to be tested, a non-magnetic metal sleeve, a temperature-sensing rod, a connecting sleeve, a supporting column, a positioning seat, a clamping assembly and a contact-type heating assembly. The present invention has the following advantages and effects: the contact-type heating assembly can contact the temperature-sensing rod of the component to be tested, and transfer the generated heat to the temperature-sensing rod of the component to be tested through heat transfer, thereby improving the temperature measurement accuracy through direct contact; the clamping assembly can conveniently clamp the connecting sleeve of the component to be tested, and the clamping assembly is driven by air, without the need for the operator to manually fix the component to be tested, which is more labor-saving and safer; the entire workbench is small in size, has no restrictions on the placement location, and can be easily carried and moved.

The utility model discloses multi-station continuous tempering equipment for gear heat treatment, and relates to the technical field of gear machining equipment. Four mounting frames are fixedly connected to the upper surface of the base, two conveying rollers are rotationally connected between the mounting frames on the front side and the rear side, a conveying belt is in transmission connection between the conveying rollers on the left side and the right side, a cooling frame is fixedly installed on the upper surface of the base, a tempering furnace is fixedly installed on the base, and the conveying belt penetrates through the interior of the tempering furnace. And a placing mechanism is arranged on the conveying belt. According to the gear blanking device, the connecting rod drives the push rod to backwards push the gear placed on the placing frame, the gear subjected to tempering heat treatment is pushed into the cooling frame to be cooled, so that the gear blanking work is realized, the gear subjected to tempering heat treatment does not need to be manually taken down from the placing frame, the gear blanking device is safer, high-temperature scalding is avoided, and the gear blanking device is energy-saving, efficient and high in practicability. And therefore, the practicability of the multi-station continuous tempering equipment for gear heat treatment is improved.
