Embodiment Construction

[0011] Referring to Fig. 1 and Fig. 2, the simple drawing mold for cement profile is composed of upper mold 1, cement surface fixing rod 2 cast on the upper mold, upper mold bushing 3, cement profile 4, blank holder 5, lower mold Counterdie pin 6 and lower die 7 form. The cement surface 4 is fixed on the upper mold 1 through the cement surface fixing rod 2 of the upper mold 1, the cement surface fixing rod 2 is cast on the upper mold 1, and the upper mold bushing 3 is embedded in the upper mold cement mold during the cement pouring process. In the surface 4, the lower mold counter-mold pin 6 is tightly fitted into the profile hole 10 of the lower mold 7. The cement profile 4 has vent holes for pouring at the parting surface of the upper mold, and a cement pouring port 8 is arranged on the bottom surface of the upper mold. When the upper die 1 works, press the blank holder 5 downwards, and after the upper die bushing 3 aligns with the lower die matching pin 6 of the lower die ...

Abstract

The simple drawing mold with cement mold surface includes one lower mold, one mold pin, one clamping ring, one upper mold, one cement mold surface fixing rod, one upper mold lining, and one cement mold surface. The lower mold and the clamping ring form one steel mold structure with steel mold surface; the upper mold is one steel mold structure with cement mold surface; the cement mold surface has one upper mold lining embedded during depositing cement; and the lower mold has corresponding mold surface hole with close fitted mold pin. The present invention has the following obvious advantages: saving in material, low numerically controlled machining cost, low cost and short making period.

Description

technical field [0001] The invention belongs to the technical field of dies, and in particular relates to a drawing die structure. Background technique [0002] At present, the simple drawing dies for automobile panels are mainly simple steel plate dies, low melting point alloy dies and epoxy resin dies. The price of low-melting-point alloy mold materials is high, close to 10,000 yuan / ton, and the mold manufacturing unit needs to have special low-melting-point alloy casting equipment, and the investment in equipment costs is even greater. The price of epoxy resin mold material is slightly lower than 10,000 yuan / ton, which is also quite expensive, and it also needs CNC machining to obtain the mold surface after it is combined on the steel frame. Simple steel plate mold material is cheap, less than half of the low melting point alloy mold, but its surface processing speed is slow and the cost is not low. [0003] The simple drawing die is mainly used to produce cover parts, ...
