Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the nouns of locality be included in term such as " upper and lower and interior " only represents the orientation of this term under normal service condition, or being commonly called as those skilled in the art's understanding, and should not be considered as the restriction to this term.
The utility model provides a kind of processing mold of gasoline saw motor cover (as illustrated in fig. 1 and 2), as shown in Figure 4, comprises patrix 1 (as shown in Figure 3) and counterdie; Counterdie comprises base 6 and protruding 4, projection 4 is arranged at the top of base 6 and projection 4 has been recessed to form lower mode cavity downwards from top, be provided with die 2 in lower mode cavity and die 2 has been recessed to form casting pressure hole 7 downwards from top, protruding 4 are provided with pilot hole with the junction of base 6 and are provided with lead 5 in pilot hole; Patrix 1 has upwards been recessed to form upper cavity from bottom, and the top of upper cavity is extended with punching press post 10 downwards and punching press post 10 can extend in casting pressure hole 7 and makes the bottom close contact of the bottom of patrix 1 and base 6 to make to form chamber of casting between upper cavity and protruding 4.
Above-mentioned processing mold installs die 2 to facilitate the inspection and maintenance of die 2 by activity in lower mode cavity, utilize the punching press post 10 in upper cavity to extend in the casting pressure hole 7 of die 2 to position die 2 simultaneously, so just, the location to die 2 can be realized quickly, prevent the surface of gasoline saw motor cover 12 from occurring crackle thus; In addition, by being provided with pilot hole in protruding 4 and the junction of base 6 and being provided with lead 5 in described pilot hole, just the gasoline saw motor cover 12 formed in casting chamber can made can to carry out close contact with lead 5 like this, just can prevent gasoline saw motor cover 12 in forming process from offseting thus, thus ensure further in casting cycle as the stability of completely shaping gasoline saw motor cover 12 is to reach the qualification rate improving product.
In the present embodiment, in order to improve the stability of die 2 further, preferably, processing mold also comprises die core seat 3, and die core seat 3 is installed in lower mode cavity and top has been recessed to form die chamber 7 downwards, and die 2 is installed in die chamber 7.So just, improve the stability of die 2 by the chucking power of die core seat 3 further, the wearing and tearing of die 2 pairs of counterdies can be prevented simultaneously by die core seat 3, and then improve the service life of processing mold.
Meanwhile, the concrete structure of lead 5 can be selected in wide scope, but the effect in order to make lead 5 can play fixing gasoline saw motor cover 12 better, and preferably, as shown in Figure 5, the top of lead 5 is extended with voussoir to the direction of protruding 4.Like this, the bottom of gasoline saw motor cover 12 just can be made to be formed with outward extending hook, this hook can closely cooperate with the voussoir at lead 5 top and then reach the function that motor cover 12 sawed by stable gasoline.In this embodiment, the process of the demoulding is as follows: first moved downward by counterdie to make lead 5 self-steering hole move upward and be separated with counterdie, then drives lead 5 to slide in the horizontal direction and lead 5 just can be made to be separated with gasoline saw motor cover 12.
In addition, in order to improve processing mold further in the course of the work, the tightness degree that patrix is combined with counterdie, preferably, the top of protruding 4 is upwards extended with locating piece 8, and patrix 1 is upwards formed with locating notch 9 from bottom, and locating piece 8 can extend in locating notch 9.So just, the top slide downward of locating notch 9 self-align piece 8 can be driven and then realize patrix and be combined closely with counterdie.This shows, locating piece 8 coordinates with locating notch 9 the assembling being not only convenient to patrix and counterdie, also can prevent patrix and counterdie from occurring rocking in the course of the work at processing mold simultaneously, and then can improve the quality of obtained gasoline saw motor cover 12.
In order to make to form through hole at the top of gasoline saw motor cover 12, preferably, the top of upper cavity is extended with casting briquetting 11 downwards, and the top of protruding 4 has been recessed to form casting indent 13 downwards, and casting indent 13 can extend in casting indent 13.
Owing to gasoline saw motor cover 12 needing mark model and other mark, in the art can by directly etching mould in upper cavity, also can by installing alphabetical mold insert to realize on the inwall of upper cavity, for the ease of changing the content of letter and the maintenance for the ease of patrix that gasoline saw motor cover 12 is formed, preferably, the inwall of upper cavity is provided with alphabetical mold insert.
On the basis of the above, the particular location of tapping hole can be selected in wide scope, enters casting chamber, preferably in order to be convenient to casting material further, the top of patrix 1 is provided with tapping hole, and casting material can enter mold cavity indoor from tapping hole through upper cavity.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
