Household electric appliance accessory casting device

Abstract

The invention relates to a household electric appliance accessory casting device which comprises a rack. A pressure casting barrel and a mould are arranged on the rack. The pressure casting barrel communicates with a discharging pipe. An outlet of the discharging pipe faces an inlet of the mould. A cutting port is reserved between the outlet of the discharging pipe and the inlet of the mould. A pressure casting block is connected into the pressure casting barrel in a sliding mode. The pressure casting block is fixedly connected with a push rod. A piston cylinder is arranged on the rack. The push rod is connected into the piston cylinder in a sliding mode. The side, away from the push rod, of the piston cylinder communicates with an air inlet pipe. An air pump is fixed to the rack. A valveis arranged on the air inlet pipe. A time-delay mechanism used for increasing the opening degree of the valve in a time-delay mode is further arranged on the rack. The rack is in sliding connection with a cutter used for cutting pressure casting materials in the cutting port. An ejection rod used for pushing the cutter is fixed to the push rod. Compared with the prior art, by arranging the pressure casting block, the time-delay mechanism, the cutter and the like according to the scheme, the operating efficiency is improved, and operating steps are also simplified.

Description

technical field [0001] The invention belongs to the field of die casting equipment for accessories, and particularly relates to a casting device for home appliance accessories. Background technique [0002] The assembly of refrigerators requires more accessories, including refrigerator shells, hinges, heat sinks, mounting brackets, pistons, shaft evaporator shells, etc. The production of these accessories can be completed using a horizontal die-casting machine. Type die casting machines generally use hydraulic cylinders as the power mechanism. When in use, the mold opening and closing of the horizontal die casting machine will produce certain vibrations. resulting in unqualified product quality. [0003] In order to solve the above problems, the utility model patent with the Chinese patent application number 201620659172.2 discloses a horizontal die-casting machine, which includes a die-casting machine body, a mold clamping mechanism and a control panel. Set in the die-cas...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the deficiencies in the prior art through the setting of the damping mechanism, but the above scheme also has the following disadvantages: during die-casting, in order to make the die-casting material in the mold cavity of the mold sufficient, the die-casting material is often made to flow from the sprue. Overflow, but when the die-casting parts are cooled, the overflowing die-casting material at the sprue will also be formed into the excess parts of the parts, requiring the operator to cut the parts, which increases the steps of the operator and reduces the production efficiency of the parts
