Abstract
The utility model discloses an improved die core mounting main frame of a pressure cast die frame, which comprises a die frame; a main frame is fabricated in the die frame; the wall surface of the main frame includes a matching surface and a non-matching surface; the matching surface is matched with the outer wall of the die core; the non-matching surface in the main frame of the die frame is in unmatched contact with the outer wall of the die core; the requirement on allowance of size dimensions and verticality is low, so that the process operation can be easily carried out; the matching surface matched with the die core in the main frame becomes shallow by generally about 1/2 or above 1/2 of the whole depth (the wall surface); and compared with the prior art, the processing difficulty of the matching surface of the main frame is greatly lowered, the allowance of size dimensions and verticality are easily ensured, the matching surface is shallow, the die mounting and dismounting processes are both convenient, the damage of the die frame and the die core is reduced and the unexpected effect can be obtained.
Description
Technical field
It is framed that the utility model relates to die casting, particularly relates to the main frame that the framed modified of die casting is installed core rod, belongs to the die casting field.
Background technology
Die casting will be according to the structure processing core and the die cavity of die cast product; Baroque core or die cavity are processed on the core rod usually; Make framed more in addition; In framed, be shaped on the core rod installation hole, then be assembled to core rod in the installation hole, this core rod installation hole in framed also is main frame.As shown in Figure 2, prior art is framed 1 ' main frame 2 ' the processing wall relate to entire depth, all be mating surface 3 '; Because the main frame degree of depth is dark, it is big to add the man-hour difficulty, for the size of main frame; Difficulty is all compared in dress mould and form removal, causes core rod or framed damage again easily.So the major defect that prior art master's frame exists is the difficulty of processing height, error is big, and the assembling trouble is damaged easily, and the product precision cannot say for sure to demonstrate,prove.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of working depth shallow, and difficulty is low, and error is little, installs to be relatively easy to the main frame that the framed modified of die casting is installed core rod.
The technical scheme that the framed modified of the utility model die casting is installed the main frame of core rod is: comprise framedly, in framed, be shaped on main frame, it is characterized in that described main frame wall comprises mating surface and empty avoiding face, said mating surface matches with the outer wall of core rod.
The utility model discloses the framed modified of a kind of die casting the main frame of core rod is installed, in framed main frame, empty avoiding face has been arranged, empty avoiding face and core rod outer kept away not to be had cooperation and contacts; The tolerance of size and perpendicularity require low, handling ease, and the mating surface with core rod in the main frame shoals; Be generally entire depth (wall) about 1/2nd or greater than 1/2nd, compared with present technology, the difficulty of processing of main frame mating surface is reduced greatly; Make the big closed tolerance and the perpendicularity of frame guarantee that easily mating surface is shallow, dress mould and form removal are all more convenient; And reduce framed and damage core rod, obtain beyond thought effect.
Description of drawings
Fig. 1 is that the main frame of the framed modified installation core rod of die casting improves technological sketch map;
Fig. 2 is the prior art sketch map.
The specific embodiment
The utility model relates to the main frame that the framed modified of a kind of die casting is installed core rod; As shown in Figure 1, comprise framedly 1, in framed, be shaped on main frame 2; It is characterized in that described main frame 2 walls comprise mating surface 3 and empty avoiding face 4, said mating surface 3 matches with the outer wall of core rod.In framed 1 main frame 2, empty avoiding face 4 has been arranged, empty avoiding face 4 and core rod outer kept away not have to cooperate and contact, and the tolerance of size and perpendicularity requirement are low; Handling ease, the mating surface with core rod in the main frame shoals, be generally entire depth (wall) about 1/2nd or greater than 1/2nd; Compared with present technology, the difficulty of processing of main frame mating surface is reduced greatly, the big closed tolerance and the perpendicularity of frame are guaranteed easily; Mating surface is shallow; Dress mould and form removal are all more convenient, and reduce framed and damage core rod, obtain beyond thought effect.
Claims (1)
