Abstract
The present invention relates to a thin-walled hollow metal handicraft and a production method thereof. The handicraft is composed of metals of plumbum, stannum, stibium and copper, wherein the proportion by weight of each component is as follows: 70 to 94% of plumbum, 0 to 20% of stannum, 5 to 20% stibium and 0 to 1% of copper. The production method of the product comprises: (1) the metals, plumbum, stannum, stibium and copper are smelted; (2) the smelted metal are injected into a hard mold made up by a metal or a nonmetal; (3) a needed cast can be formed after the smelted metal closely near to the outer wall is solidified to a needed wall thickness; if the injected quantity is lager than the cast needed quantity, the needed cast can be formed by pouring out the unsolidified metal. The product produced by the method has the following advantages: 1. the weight of the cast is light. The wall of the produced cast is thinner and lighter than a cast produced by an investment casting method and a metal mold casting method which adopts a mold core. 2. Productive efficiency is high. Compared with adopting the investment casting method, the productive efficiency raises more than 5 times; compared with adopting the mold core metal mold casting method, the productive efficiency raises more than that of times. 3. Cast cost is low. Compared with adopting the investment casting method, the cast cost reduces more than 1 time; compared with adopting the mold core metal mold casting method, the cast cost reduces 0.5 to 1 times.
Description
One, technical field:
The invention belongs to a kind of metal handicrafts and manufacture method thereof, be specifically related to a kind of thin-walled, hollow metal artwork and manufacture method thereof.
Two, background technology:
Traditional castmethod that is used to cast thin-walled, hollow metal artwork is: lost wax process.Lost wax process is because the casting technique complexity, and the operation process is many, in foundry technology process, requires the technology strictness, foundary loss rate height, thereby make casting cost height, expense big.When adopting traditional diecasting method to make thin-walled, hollow metal artwork foundry goods, must adopt core, adopt core first to increase the expense of making core; Second is difficult to accomplish the very thin thickness of wall and very even; The 3rd technology difficulty is big, also causes casting cost higher thus.
Three, summary of the invention:
Technical problem to be solved by this invention: when making thin-walled, hollow metal artwork foundry goods, do not adopt core, also do not adopt lost wax process.And provide a kind of new thin-walled, hollow metal artwork and manufacture method thereof.
The technical solution used in the present invention is: a kind of thin-walled, hollow metal artwork, and it is made up of metallic lead, tin, antimony and copper, and the weight content of each component is: plumbous 70-94%, tin 0-20%, antimony 5-20%, copper 0-1%, and the content of tin and copper is not 0.The manufacture method of this product comprises: (1) is with metallic lead, tin, antimony and copper melting; (2) metal after the melting is injected the die of metal or nonmetal manufacturing; When (3) treating near the metal freezing of outer wall, promptly form required foundry goods,, can form required foundry goods if injection rate greater than the foundry goods requirement, is poured out not solidified metal to required wall thickness.
Because the present invention has adopted technique scheme, therefore compare with background technology, have the following advantages: 1, casting weight is light.The casting section thickness that the casting section thickness that can make is produced than the diecasting method of lost wax process and employing core is thinner, casting weight is lighter.2, production efficiency height.Than adopting investment casting method production efficiency to improve more than 5 times, than adopting core diecasting method production efficiency to improve 3 times.3, casting cost is low.Reduce more than 1 times than the casting cost that adopts investment casting method to produce, reduce 0.5-1 doubly than the casting cost that adopts core diecasting method to produce.
Four, embodiment:
Embodiment 1
A kind of thin-walled of Yellow Crane Tower model, hollow metal artwork are made up of metallic lead, tin, antimony and copper, and the weight content of each component is: lead 79.9%, tin 6%, antimony 14%, copper 0.1%; The manufacture method of this product comprises: (1) metallic substance melting according to the above ratio; (2) metal after the melting is injected the die of metal or nonmetal manufacturing; When (3) treating near the metal freezing of outer wall, promptly form required foundry goods,, can form required foundry goods if injection rate greater than the foundry goods requirement, is poured out not solidified metal to required wall thickness.
Claims (2)
1, a kind of thin-walled, hollow metal artwork, it is characterized in that: it is made up of metallic lead, tin, antimony and copper, and the weight content of each component is: plumbous 70-94%, tin 0-20%, antimony 5-20%, copper 0-1%, and the content of tin and copper is not 0.
2, a kind of method of producing thin-walled as claimed in claim 1, hollow metal artwork, it is characterized in that: this manufacture method comprises: (1) is with metallic lead, tin, antimony and copper melting; (2) metal after the melting is injected the die of metal or nonmetal manufacturing; When (3) treating near the metal freezing of outer wall, promptly form required foundry goods,, can form required foundry goods if injection rate greater than the foundry goods requirement, is poured out not solidified metal to required wall thickness.
