Thermostat base mold

Abstract

The invention relates to a thermostat base mold. The thermostat base mold comprises a top plate, wherein a sprue cup is arranged at the left side of the upper end surface of the top plate; the lower end surface of the top plate is provided with a No.1 groove and the No.1 groove is internally provided with an upper mold; the upper mold is internally provided casting hole pins; pin heads of the casting hole pins are positioned on the upper end surface of the upper mold; a lower mold is arranged below the upper mold; a cushion plate is arranged below the lower mold; the lower end surface of the cushion plate is provided with a No.2 groove; the lower mold is clamped insidethe No.2 groove; a lower pressing plate is arranged below the cushion plate; guide columns, the upper ends of which are clamped in the cushion plate, are clamped in the lower pressing plate; base plate groups are arranged below the lower pressing plate, and are internally provided with guide sleeves matched with the guide columns, and are also internally provided with demolding pins; pin heads of the demolding pins are all clamped insidethe base plate groups. A shaft of each air cylinder provided by the invention is convenient to contract, and a casting can be subjected to demoldingconveniently; meanwhile, supporting columns sleeving the shafts of the air cylinders and propping rods are convenient to replace without replacing the whole air cylinders; the cost can be reduced; imprints of a casting can be changed conveniently by replacing arc plates without replacing the whole upper mold; the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mold equipment for manufacturing auto parts, in particular to a thermostat seat mold. Background technique [0002] A car thermostat is a valve that controls the flow path of coolant. It is an automatic thermostat device that usually contains a temperature-sensing component that opens and controls the flow of air, gas or liquid by expansion or contraction. The thermostat seat is the carrying device of the car thermostat. Due to the complex shape of the thermostat seat and the inconvenient clamping, it is extremely inconvenient to process the connecting holes on the thermostat seat. It is even more difficult to make it with traditional sand casting molds. Mold cavity to accommodate complex outer surface of thermostat housing. [0003] In order to improve the tensile strength, toughness and molding rate of the thermostat seat, reduce the amount of sand used, and improve production efficiency, people began ...
