Abstract
The utility model relates to an expansion and shrinkage molding die, comprising an expansion sub die, a shrinkage sub die and a mixing bar; the expansion sub die comprises an expansion locating lower die and an expansion upper die which is provided with an external locating ring; the shrinkage sub die comprises a shrinkage locating lower die and a shrinkage upper die which is provided with an internal locating core; in machining of expansion and shrinkage molding, a part to be machined is arranged on the expansion locating lower die firstly, the expansion upper die carries out expansion molding on the part to be machined, and then the part to be machined is arranged on the shrinkage locating lower die, and the shrinkage upper die carries out shrinkage molding on the part to be machined. Compared with the prior art, the die provided by the utility model has the advantages of being smooth in molding surface, being capable of meeting design requirements, and the like.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of closing-in forming die that dilates.
Background technology
Generally adopt when production dilates and close up simultaneous product at present, first dilate the twice processing technology that closes up again, swollen mouthful generally dilates material with the convex tendon on mould, and Closing in die is used for the top that dilates is zoomed in.Existing closing-in forming die such as Fig. 1-shown in Figure 2 of dilating, this mould is completed the expansion shaped insertion-type of part to be processed by dilating upper mold core, complete the closing in moulding of part to be processed by closing in patrix outside fix circle.Existing one exists the product that dilates and close up simultaneously, requires to dilate face round and smooth, dilates the R(radian of face) larger but to dilate the width of face smaller, dilate and close up after axiality require higher as the mould production with original mechanism.The problem that adopts existing mold processing to exist is:
1, dilate the R of face smaller, and the product axiality after dilating is relatively poor;
2, dilate facial contour not round and smooth, the distortion of closing in shape can not be satisfied production requirement.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of forming surface round and smooth, can meet design requirement dilate closing-in forming die.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of closing-in forming die that dilates, comprise and dilate submodule, closing in submodule and dnockout rod, the described submodule that dilates comprises and dilates the location counterdie and with the patrix that dilates of outside fix circle, and described closing in submodule comprises the location counterdie and with the closing in patrix of interior locating core of closing up.
The described patrix that dilates comprises and dilates upper mold core and dilate patrix outside fix circle, and the described upper mold core that dilates is located at and dilates in patrix outside fix circle.
The described upper mold core both sides of dilating are provided with the projection that dilates for part.
Described dilating is provided be used to the through hole that passes the dnockout rod in the middle of upper mold core.
Describedly dilate patrix outside fix circle and dilate the gap of leaving between upper mold core be used to placing part to be processed.
Described closing in patrix comprises locating core and closing in patrix outside fix circle in the closing in patrix, and in described closing in patrix, locating core is located in closing in patrix outside fix circle.
Described closing in patrix outside fix circle is provided with the arcuation groove that closes up for part.
Be provided be used to the through hole that passes the dnockout rod in the middle of locating core in described closing in patrix.
Compared with prior art, the utlity model has following advantage:
One, profile: the utility model is round and smooth by the product R that dilates after patrix outside fix circle has guaranteed to dilate that dilates upper mold core and increase, is out of shape little;
Two, size: the utility model has guaranteed that by work when locating core in closing in patrix outside fix circle and closing in patrix profile, R and all relative dimensions of final products reach the requirement of drawing fully.
Description of drawings
Fig. 1 is the machining sketch chart that dilates of existing mold;
Fig. 2 is the closing in machining sketch chart of existing mold;
Fig. 3 is the machining sketch chart that dilates of the utility model mould;
Fig. 4 is the closing in machining sketch chart of the utility model mould.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment is implemented as prerequisite take technical solutions of the utility model, provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
As Fig. 3-shown in Figure 4, a kind of closing-in forming die that dilates, comprise and dilate submodule, closing in submodule and dnockout rod 3, the described submodule that dilates comprises and dilates location counterdie 1 and with the patrix that dilates of outside fix circle, described closing in submodule comprises the location counterdie 8 and with the closing in patrix of interior locating core of closing up, when carrying out processing and forming, part to be processed is placed on counterdie, and dnockout rod 3 passes and is embossed on part to be processed.
As shown in Figure 3, the described patrix that dilates comprises and dilates upper mold core 2 and dilate patrix outside fix circle 4, and the described upper mold core 2 that dilates is located at and dilates in patrix outside fix circle 4.Dilate upper mold core 2 both sides and be provided with the projection that dilates for part, the centre is provided be used to the through hole that passes the dnockout rod; Dilate patrix outside fix circle 4 and dilate 2 of upper mold core and leave be used to the gap of placing part to be processed.
As shown in Figure 4, described closing in patrix comprises locating core 5 and closing in patrix outside fix circle 6 in the closing in patrix, and in described closing in patrix, locating core 5 is located in closing in patrix outside fix circle 6.Described closing in patrix outside fix circle 6 is provided with the arcuation groove that closes up for part, is provided be used to the through hole that passes the dnockout rod in the middle of locating core 5 in described closing in patrix.
The above-mentioned operation that dilates closing-in forming die is as follows:
When dilating the closing in processing and forming, first part to be processed is placed on and dilates on the counterdie of location, dilate patrix and treat processing parts and carry out expansion shaped insertion-type, round and smooth by the product R that dilates after patrix outside fix circle has guaranteed to dilate that dilates upper mold core and increase, be out of shape little; And then part to be processed is placed on the location counterdie that expand to close up, the closing in patrix is treated the processing parts moulding of closing up, and under the work of locating core, has guaranteed the axiality of product and the shape of closing in closing in patrix outside fix circle and closing in patrix.
