Technical field
The utility model relates to the concavo-convex powder injection-molded mould of taking turns of a kind of rotating shaft, relates in particular to a kind of metal powder injection molding mould that has the push pin device of caving in.
Background technology
Metal powder injection molding (MIM) is a new forming technique that develops rapidly in the world in recent years, it is advantageous that the small-sized parts that can form any complicated shape, and each position density of goods is even, excellent performance.General technological process is for to be uniformly mixed into fine metal dust and organic binder for having the material of rheological characteristic, the die cavity that adopts advanced injector injection to have part shape forms blank, remove adhesive and through sintering, make its high compaction become metallic article, one of this key wherein is exactly to utilize mould to obtain given shape.
Powder injection forming concavo-convex function of use of taking turns has determined it to having relatively high expectations of working face up and down; and ejector pin of die set will design in the plane inevitably; normal push rod ejects the position and is opened on the table plane of mould core; mould in process of production; thimble is motion repeatedly in centre hole; regular meeting ejects overlap because of wearing and tearing at product, and is higher than product surface, has had influence on concavo-convex working face of taking turns.
The utility model content
The technical problems to be solved in the utility model is: a kind of concavo-convex mould of taking turns of powder injection forming that can not influence the invaginating thimble design of product working surface is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of powder injection-molded concavo-convex mould of taking turns that has the push pin device of caving in, comprise the cover half fixed head, cover half, dynamic model, thimble fixed head and dynamic mould fixing plate, described cover half fixed head upper end is connected with centring ring, described cover half fixed head is installed on the cover half, described cover half and dynamic model are oppositely arranged, described dynamic model is installed on the dynamic mould fixing plate, be provided with the thimble fixed head between described dynamic model and the dynamic mould fixing plate, described thimble fixed head is provided with thimble, and the thimble position of described mould core is provided with a step.
According to another embodiment of the present utility model, a kind of powder injection-molded concavo-convex mould of taking turns that has the push pin device of caving in comprises that further described step is diameter 1.2mm, dark 0.1mm, top chamfer R0.1mm.
According to another embodiment of the present utility model, a kind of powder injection-molded concavo-convex mould of taking turns that has the push pin device of caving in comprises that further described push rod gos deep into core rod 0.1-0.12mm.
According to another embodiment of the present utility model, a kind of powder injection-molded concavo-convex mould of taking turns that has a push pin device of caving in further comprises and is provided with the cover half core rod in the described cover half.
According to another embodiment of the present utility model, a kind of powder injection-molded concavo-convex mould of taking turns that has a push pin device of caving in further comprises and is provided with the dynamic model core rod in the described dynamic model.
According to another embodiment of the present utility model, a kind of powder injection-molded concavo-convex mould of taking turns that has the push pin device of caving in comprises that further described step is the volcano shape of the mouth as one speaks.
The utility model has solved the defective that exists in the background technology, and push rod is ejected by traditional direct plane and changes the design of invaginating thimble into, has solved the harmful effect that product push rod overlap causes product better; Save manually to repair and removed the operation that ejects overlap, prevented that manual operation to injecting damaging and damaging of training part product appearance, having improved production efficiency and product appearance quality.

Fig. 2 is the enlarged drawing of A among Fig. 1.
Wherein: 1, centring ring, 2, the cover half fixed head, 3, cover half, 4, dynamic model, 5, the thimble fixed head, 6, dynamic mould fixing plate, 7, thimble, 8, step.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of powder injection-molded concavo-convex mould of taking turns that has the push pin device of caving in shown in Fig. 1-2, comprise cover half fixed head 2, cover half 3, dynamic model 4, thimble fixed head 5 and dynamic mould fixing plate 6, described cover half fixed head 2 upper ends are connected with centring ring 1, described cover half fixed head 2 is installed on the cover half 3, described cover half 3 is oppositely arranged with dynamic model 4, described dynamic model 4 is installed on the dynamic mould fixing plate 6, be provided with thimble fixed head 5 between described dynamic model 4 and the dynamic mould fixing plate 6, described thimble fixed head 5 is provided with thimble 7, and thimble 7 positions of described mould core are provided with a step 8.
As shown in Figure 2, in mould when design, increased a small stair 8 in the position of the thimble 7 of die, likeness in form volcanic crater moulding, even on product, eject overlap after the moulding, but overlap is trapped in the counterbore, can not exert an influence by high out-of-plane, and described step 8 is of a size of diameter 1.2mm during actual design, dark 0.1mm, top chamfer R0.1mm.
As shown in Figure 2, thimble gos deep into core rod 0.1-0.12mm when product surface designs, after product injection moulding, the thimble overlap is trapped in the counterbore, can make overlap not be higher than product surface, so both can guarantee the quality of product, also can save the operation of manually repairing except that the thimble overlap.
Powder injection forming concavo-convex function of use of taking turns has determined it to having relatively high expectations of working face up and down; and ejector pin of die set will design in the plane inevitably; normal push rod ejects the position and is opened on the table plane of mould core; mould in process of production; thimble is motion repeatedly in centre hole; regular meeting ejects overlap because of wearing and tearing at product, and is higher than product surface, has had influence on concavo-convex working face of taking turns.
When utilizing this mold injects, the first, the push rod design is ejected by traditional direct plane and changes the design of invaginating thimble into, can better solve the harmful effect that product push rod overlap causes product; The second, save manually to repair to remove and ejected the overlap operation, thereby can prevent that manual operation to the damaging and damaging of injection blank product appearance, having improved the presentation quality of production efficiency and product.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
