Abstract
The utility model provides a pin type dewaxing stick for investment casting, it includes barred body and joint, the barred body is a round bar, the diameter of round bar reduces to form the tapering by one end to the other end gradually, connecting and being a disk, the terminal surface of disk is connected with the main aspects of barred body, and the diameter of disk is greater than the main aspects diameter of cone. The utility model discloses simple structure, convenient to use has improved production efficiency.
Description
Technical field
The dewaxing rod that the utility model uses when relating to a kind of model casting, belongs to melted module precise casting technology field.
Background technology
In the process of investment casting moulding shell, need wax to deviate from from the dewaxing passage of shell, form cavity, and due to the general more complicated of casting structure of model casting, the wax under normal circumstances in shell can not purify completely.When leaving residual wax in shell, bring a lot of problem with regard to giving operation below: such as produce the casting flaw such as pore, slag inclusion, affect casting quality.
How to be purified from shell by wax is the problem that must consider as far as possible, current common practice be running gate system and multiple wax part are carried out group set after on each wax part the bonding rod that dewaxes, composition module.The dewaxing rod of current use is mainly cylindricality dewaxing rod 4 and arc dewaxing rod 5, the diameter of dewaxing rod is 4-6mm, general bonding location and bonding way are connected with a wherein wax part 2 one end of dewaxing rod, and the other end is linked on running gate system 3 or adjacent wax part, as shown in Figure 3 and Figure 4.
For illustrated two kinds of conventional dewaxing rods, all easily have problems in setting and removal.First, because the bonding of the rod that dewaxes just can must be carried out, so need enough operating spaces when bonding after multiple wax part first being completed group tree, otherwise wax part can be damaged, which limits the use of dewaxing rod, for some products, for vacating space, yield rate can only be reduced.Secondly, after casting complete cooling forming, when isolating single foundry goods by module, dewaxing rod is not easy to remove, and residual dewaxing rod is inconvenient to cut, and abrasive band can only be used to grind off, waste time and energy.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of structure simple moltening mold castings pin type dewaxing rod, easy to use, improves production efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of moltening mold castings pin type dewaxing rod, it comprises barred body and joint, described barred body is a round bar, the diameter of described round bar is reduced to form tapering to the other end by one end gradually, described joint is a disk, the end face of disk is connected with the large end of barred body, and the diameter of disk is greater than the outside diameter of cone.
Above-mentioned moltening mold castings pin type dewaxing rod, the tapering of described round bar is 1:16-1:20, and the outside diameter of barred body is 3-3.5mm, and the length of barred body is 18-22mm.
Above-mentioned moltening mold castings pin type dewaxing rod, the diameter of described disk is 4-5mm, and the thickness of disk is 1-2mm.
The utility model makes simple and convenient, and bonding does not limit by product structure, applied widely.In use pin type dewaxing rod is bonded at the position of needs, was knocked out before dewaxing, then dewax, facilitate liquid wax to flow out shell.Pin type dewaxes excellent moderate length, can not be damaged in shell process processed, simple to operate when needing to remove, and reduces labour intensity, improves production efficiency.

Fig. 4 to be cylindricality dewaxing rod with arc dewax excellent structure and using state figure thereof.
In figure, each list of reference numerals is: 1, pin type dewaxing rod, 1-1, barred body, 1-2, joint, 2, wax part, 3, running gate system, 4, cylindricality dewaxing rod, 5, arc dewaxing rod.
Detailed description of the invention
Referring to Fig. 1, a kind of moltening mold castings pin type dewaxing rod, it comprises barred body 1-1 and joint 1-2, and described joint 1-2 is connected with one end of barred body 1-1.
Described barred body 1-1 is a round bar, and the diameter of described round bar is reduced to the other end gradually by one end, form a tapering, and wherein the size of tapering is 1:16-1:20, and when dewaxing, liquid wax outwards flows out from large end to small end.The outside diameter of barred body 1-1 is 3-3.5mm, and the length of barred body 1-1 is 18-22mm.In this diameter and length range, pin type dewaxing rod is not easy to damage in bonding process, easily keeps in shell process processed, easy to operate; Simultaneously when carrying out dewaxing, needing to knock out, can remove smoothly, alleviate labour intensity.
Described joint 1-2 is arranged on the large end of barred body 1-1, and joint 1-2 is a disk, and the end face of disk is connected with the large end of barred body 1-1, and the diameter of disk is 4-5mm, is greater than the outside diameter of cone, strengthens bonding stability during bonding operation.The thickness of disk is 1-2mm.
As shown in Figure 2, when organizing number, after being connected with running gate system 3 by multiple wax part 2, joint 1-2's using state of pin type dewaxing rod of pin type dewaxing rod is connected with wax part 2, and described barred body 1-1 suspends.Pin type dewaxing rod bonding wax is bonded in the position that wax part needs, and carries out shell processed after completing module, is knocked out at the position of pin type dewaxing rod suspension, just form hole, facilitate liquid wax to flow out from shell after wax fusing after shell completes before dewaxing.With plastic refractory, hole is blocked before casting, wait to be cast.The thickness of shell is generally 5-6mm, knocks out pin type dewaxing rod along shell root, and residual pin type dewaxing rod is highly also 5-6mm, easily removes.
