Abstract
A kind of 3D printing wax pattern fusible pattern gray cast iron bracket casting described in the utility model, two circular pin holes are distributed in one end of upper backup pad, and the centre of upper backup pad is equipped with upper annular groove and the first round positioning pin；Transition is connected by the first dowel between upper backup pad and lower bottom base, the first dowel is equipped with the second circular pegs；Lower bottom base is provided with lower annular groove, and centre passes through the second dowel and third dowel and connecting plate transition；Lower bottom base side is successively arranged the 4th circular pegs, the 5th circular pegs, arc-shaped seat；Second dowel is equipped with third circular pegs.To the product digital-to-analogue, gray cast iron bracket casting is quickly produced, cost is greatly reduced using 3D printing casting wax pattern fusible pattern model by the design of reasonable structure, casting Technology Design, yield rate is improved, shortens the castings production period.
Description
Technical field
The utility model relates to field of automobile, in particular to a kind of 3D printing wax pattern fusible pattern gray cast iron bracket casting
Part.
Background technique
Casting, which refers to inject liquid alloy in casting mold, is allowed to cooling, solidification, and is post-processed, and made of metal is eventually become
A kind of production method of product.
Wax pattern investment casting method is that the casting to be done first is designed to three-dimensional digital model, and model is made with wax material, and
Model is welded on gate stick with same material, mould group (can be individually one group when casting is big) be made, is dipped on mould group surface
Upper fireproof coating (mixture of waterglass or silica solution and fine sand), then be sprinkled with fire sand, (be stained with slurry, stucco will be repeated several times, make
Layer of sand is sufficiently thick), it after its dry solidification, is heated to mould group, wax material is deviate from from cast gate, form ghost.Ghost is roasted,
Firm formwork is made, metal liquid is poured into from cast gate, after condensation, just becomes metal casting.
For castings of gray cast iron product development due to factors such as Mold Makings, the production cycle is long, needs molten using wax pattern
The method of modulus mould printing rapid shaping, which is realized, makees casting shell mould without molding, and casting obtains casting.
Utility model content
The purpose of the utility model is to provide a kind of 3D printing wax pattern fusible pattern gray cast iron bracket castings.
In order to solve the above technical problems, the utility model is realized as follows:
A kind of 3D printing wax pattern fusible pattern gray cast iron bracket casting, including circular pin hole (21), upper annular groove (22), first
Round positioning pin (23), upper backup pad (24), the first dowel (25), the second circular pegs (26), third circular pegs (27), second
Dowel (28), lower bottom base (29), third dowel (30), the 4th circular pegs (31), the 5th circular pegs (32), arc-shaped seat
(33), lower annular groove (34), connecting plate (35)；
Two circular pin holes (21) are distributed in one end of upper backup pad (24), and the centre of upper backup pad (24) is equipped with upper annular
Groove (22) and the first round positioning pin (23)；Between upper backup pad (24) and lower bottom base (29) even by the first dowel (25)
It takes over and crosses, the first dowel (25) is equipped with the second circular pegs (26)；Lower bottom base (29) is provided with lower annular groove (34), intermediate
Pass through the second dowel (28) and third dowel (30) and connecting plate (35) transition；Lower bottom base (29) side is successively arranged the 4th
Circular pegs (31), the 5th circular pegs (32), arc-shaped seat (33)；Second dowel (28) is equipped with third circular pegs (27).
The good effect of the utility model is: the present apparatus is to the complexity for making, manufacturing experimently in conventional casting techniques mold process
Process optimizes, and in such a way that no mould prints wax pattern fusible pattern, makes cast model, saves casting mould cost, realizes casting
Part quickly manufactures, and reduces the castings production preparatory period, and facilitates foundry enterprise and realize green manufacturing, reduces mold and manufactured
Environmental pollution in journey is conducive to protect environment.

Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, 2, a kind of 3D printing wax pattern fusible pattern gray cast iron bracket casting described in the utility model, including circle
The round positioning pin 23 of pin hole 21, upper annular groove 22, first, upper backup pad 24, the first dowel 25, the second circular pegs 26, the
Three circular pegs 27, the second dowel 28, lower bottom base 29, third dowel 30, the 4th circular pegs 31, the 5th circular pegs 32, arc
Seat 33, lower annular groove 34, connecting plate 35.
Two circular pin holes 21 are distributed in one end of upper backup pad 24, and the centre of upper backup pad 24 is equipped with upper annular groove 22
With the first round positioning pin 23；Transition, the first connection are connected by the first dowel 25 between upper backup pad 24 and lower bottom base 29
