Abstract
The utility model discloses a kind of phase disc molding former, including core rod and die sleeve, the core rod is fixed in the die sleeve, die cavity is offered on the core rod, the die cavity is integrally formed with core rod, and the size of the die cavity is adapted with product to be formed, and the through hole being adapted with phase disk signal teeth is provided with the die cavity, gradually the heart extends the side wall of the die cavity thereto from top to bottom, and the connected mode of arc transition is used between the side wall of die cavity and bottom.Its remarkable result is：By by the belly of die cavity and the cylindrical monolithic construction for being made of one shaping, solving the Burr Problem caused by die clearance, and the mould strength so worked it out is good, it is not easy to damage, effectively increase production efficiency, reduce entreprise cost.
Description
Technical field
Automotive parts manufacturing technology is the utility model is related to, is that a kind of phase disc molding is cloudy specifically
Mould.
Background technology
Steering is the tie point between vehicle and driver.It not only provides direction controlling and road feel feedback, also deep
The characteristics of carving influence vehicle and performance.And phase disk is the important component in engine cam, at present to save processing cost,
Ensure structural strength, produced more using powder metallurgical technique.
However, in traditional powder metallurgical technique, because existing mould has gap, product edge is caused hair to be present
Thorn, not only influences product quality, and needs to carry out post-processing, reduces efficiency, adds cost.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of phase disc molding former, by die cavity
Belly be integrally formed with cylindrical, and arc transition between cavity lateral and bottom surface can effectively solve the problem that the Burr Problem of product.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of phase disc molding former, its key are：Including core rod and die sleeve, the core rod is fixed on described
In die sleeve, die cavity is offered on the core rod, the die cavity is integrally formed with core rod, and the size of the die cavity and production to be formed
Condition adapts to, and the through hole being adapted with phase disk signal teeth is provided with the die cavity, the side wall of the die cavity is from top to bottom
Gradually the heart extends thereto, and the connected mode of arc transition is used between the side wall of die cavity and bottom.
By the way that die cavity and core rod are integrally formed, and by the side wall of die cavity, gradually the heart extends thereto from top to bottom, simultaneously
Arc transition is used between the side wall of die cavity and bottom so that mould is solved because gap causes not with gap
Phase disk there is the problem of burr, not needing subsequent handling to phase panel surface carry out post-processing, improve production effect
Rate, reduce production cost；The overall structural strength of former is more enhanced, extends service life.
Further, the core rod is arranged concentrically with die sleeve.
Further, the angle between the side wall of the die cavity and its center line is 2~5 °.
Further, the bottom of the die sleeve extends to form step laterally, and positioning hole is offered on the die sleeve.
Further, the edge of the core rod and die sleeve carries out chamfered.
Remarkable result of the present utility model is：It is simple in construction, it is easy to accomplish, by the way that the belly of die cavity is made into one with cylindrical
Body formed monolithic construction, solve the Burr Problem caused by die clearance, and the mould strength so worked it out
It is good, it is not easy to damage, effectively increase production efficiency, reduce entreprise cost.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is the close-up schematic view of B in Fig. 2；
Fig. 4 is the structural representation of the die cavity.
Embodiment
Specific embodiment of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to 4, a kind of phase disc molding former, including core rod 1 and die sleeve 2, the installation of core rod 1 are solid
It is scheduled in the die sleeve 2, die cavity 3 is offered on the core rod 1, the die cavity 3 is integrally formed with core rod 1, and the die cavity 3
Size is adapted with product to be formed, and four through holes 4 being adapted with phase disk signal teeth, institute are provided with the die cavity 3
State the side wall gradually heart extension thereto, and the company of arc transition is used between the side wall of die cavity 3 and bottom from top to bottom of die cavity 3
Connect mode.
The core rod 1 is can be seen that from Fig. 1 and Fig. 2 to be arranged concentrically with die sleeve 2.
Concrete technology requirement in actual production, the angle α between the side wall of the die cavity 3 and its center line are
3°。
As a kind of common die sleeve structure, the bottom of the die sleeve 2 extends to form step 5 laterally, on the die sleeve 2
Positioning hole 6 is offered, so as to be conveniently accomplished the overall assembling of former by above-mentioned step 5 and positioning 6.
In the present embodiment, the edge of the core rod 1 and die sleeve 2 carries out chamfered.
