Abstract
The utility model discloses a die casting of a lower cover of an automobile thermostat with a special-shaped structure, which comprises a lower cover inner cavity and a die casting plug. The lower cover inner cavity is formed by the process of pulling cores from the upper direction, the lower direction and a side direction, and the die casting plug is pressed into the lower cover inner cavity from a side opening. The lower cover inner cavity is provided with a first inner cavity and a second inner cavity, and the internal widths of both the first inner cavity and the second inner cavity are larger than the widths of outlets of the first inner cavity and the second inner cavity. By the aid of die casting technique, a special-shaped structure of an inner cavity of an original sand casting is changed into two die casting units and a cover plug by means of smart geometric decomposition, combination portions are machined after a die casting process is completed, the cover and the plug are integrally assembled after assembly conditions are met, accordingly, complete technical conversion of the sand casting is completed, and an original mode with shortcomings of long production period, high material consumption and low efficiency is improved.
Description
Technical field
The utility model relates to a kind of special-shaped automobile spare, particularly relates to a kind of automobile polymorphic structure thermostat lower cover parts that adopt casting die to produce.
Background technology
At present, the Chinese Foundry of tracing to the source development history, China is the earliest one of cradle in the world.But to modern age, industry still was in backward state up to 1976.Since 1977, because industrial departments such as China's machinery, electronics, light industry, instrument, traffic is flourish, the demand of casting mould is quantitatively got more and more, require increasingly highly qualitatively, Lead Time is shorter and shorter.Therefore; Caused of the great attention of China relevant department, mould has been classified as " six or five " and " the Seventh Five-Year Plan " planning emphasis scientific research project, through these series of measures to casting mould industry; Make casting mould industry that very great development arranged, die casting is used widely.
Traditional automobile polymorphic structure thermostat lower cover parts are to adopt the technology of core casting to accomplish; Because the characteristic of core casting process; Make that it is in that working environment is the poorest, material expends maximum, in the single-piece manual production the longest inferior position consuming time; Because of its flexibly in shaping characteristic be again the casting industry scarce unique means of can not slitting, the inside abnormity of core cast is the compression mod tradition insurmountable difficult problem of mode of loosing core.
Summary of the invention
The purpose of the utility model is to provide a kind of automobile polymorphic structure thermostat lower cover die casting, solves foundry goods inside through casting die and looses core and the special-shaped problem in the inside of core cast.
The purpose of the utility model and to solve its technical problem be that technical scheme below adopting realizes.A kind of automobile polymorphic structure thermostat lower cover die casting according to the utility model proposes comprises: the lower cover inner chamber of loosing core and accomplishing from upper and lower and a side directions respectively; Reach the die casting plug that is pressed into the lower cover inner chamber by the side openings place.
Said lower cover inner chamber has one first inner chamber and one second inner chamber.
The inner width of said first inner chamber is greater than the width of its outlet.
The inner width of said second inner chamber is greater than the width of its outlet.
By technique scheme, the advantage that the utility model automobile polymorphic structure thermostat lower cover die casting has is:
The utility model makes roughing sand core cavity polymorphic structure into two die castings, cover body plug through decomposing for how much cleverly through casting die technology; After completion die casting, through to binding site processing, reach assembled condition and again cover body and plug are assembled into an integral body, thereby accomplish the whole technologies conversions of this sand foundry goods, making originally, production cycle length, many, the inefficient patterns of materials are improved; Compare the sand foundry goods of existing explained hereafter, its intensity of the die casting of the utility model has improved 25～30%, and dimensional accuracy is high, and fineness is good, and processing capacity is very little.

The specific embodiment
See also shown in Fig. 1 and 2, the utility model automobile polymorphic structure thermostat lower cover die casting, its structure mainly comprises: lower cover inner chamber 10 and die casting plug 40.This lower cover inner chamber 10 is respectively from the completion of loosing core of upper and lower and a side directions; It has one first inner chamber 20 and one second inner chamber 30.The inner width of this first inner chamber 20 is greater than the width of its first outlet 21.The inner width of this second inner chamber 30 is greater than the width of its second outlet 31.The lower cover parts of this polymorphic structure be the traditional mode of loosing core can not accomplish.
The part that forms first inner chamber 20 and second inner chamber, 30 shapes is split into another die casting, and " plug " promptly shown in Figure 3, and lower cover inner chamber as shown in Figure 2 can be loosed core from A, B, three directions of C respectively and accomplished the moulding of lower cover inner chamber.In addition; Can carry out fine finishining to the cylindrical of die casting plug 40 and the endoporus of die casting lower cover 10; Again the A end of plug 40 from Fig. 4 is pressed in the hole of lower cover 10, forms size, form and the on all four product of Fig. 1, thereby accomplish whole production processes of casting die new technology.
The molding process of the utility model automobile polymorphic structure thermostat lower cover die casting can be explained as follows:
At first, through die casting machine, compression mod, the manual work mold insert of packing into, motor-driven matched moulds; Moreover, hand stock, motor-driven back under pressure, pressure-cure, motor-driven die sinking ejects foundry goods; At last, mold insert is taken out in artificial pickup, and the cleaning die casting, obtains the die casting finished product.
Satisfying the extrusion process condition is this mould design difficulty, and the structural design of interior mold insert reaches the interior location of mold insert in mould, and interior mold insert is installed and taken out in the production process, and the interior mold insert of manufacturing interchangeability is used and produced.
Compare the core cast that existing technology is made, the advantage of the utility model automobile polymorphic structure thermostat lower cover die casting can be explained as follows:
1. use the plurality of geometries compound mode constitute in mold insert, solve young in the big problem of loosing core.
2. main points: stable, accurate localization structure, reasonably service life.
3. consumptive material relatively: former technology core cast substance 750 grams, existing die casting substance 395 grams reduce aluminium alloy materials 47%.
4. production efficiency relatively: 10 minutes/part of former technology core cast production time per piece, 1 minute/part of die casting production time per piece enhances productivity 900%.
5. numerous advantages: intensity improves 25～30%, and dimensional accuracy is high, and fineness is good, and processing capacity is very little.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; So every the utility model technical scheme content that do not break away from, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
