Description
Technical field
Technical field of mold is the utility model is related to, specifically a kind of combined type mould of high-strength bolt turret head.
Background technology
In the production process of high-strength bolt, its turret head typically coordinates hot pier machine-shaping by mould.Existing shaping
Mould is made using heated die steel, and the top of mould goes out hexagonal die cavity, the center of hexagonal die cavity by electrical discharge machining
Place goes out to penetrate into the cylindrical die cavity of bottom by electrical discharge machining.During Re Dun, after accessory is put into, in the work of pressure
With lower deformation, constrained by hexagon die cavity, form turret head.The defects of such mould is：During Re Dun, hexagon type
The bottom of chamber can bear very big impulsive force, cylinder die cavity tip position more in this way, heated die steel is easier out
Split or deform, service life is very short, and needs integral replacing after cracking/deformation, adds production cost.
Utility model content
The purpose of this utility model is overcome the shortcomings of in above-mentioned background technology, there is provided a kind of group of high-strength bolt turret head
Box-like mould, there is long lifespan, simple in construction, easy to use, lower-cost feature.
What technical purpose of the present utility model was realized in：A kind of combined type mould of high-strength bolt turret head,
It is characterized in that：It is coaxial with core rod including a matrix with hexagon die cavity and the core rod with cylindrical mold cavity, matrix
Arrange, a counterbore is formed with the top of core rod, the top sides edge of cylindrical mold cavity is arc port.
Further, the matrix is arranged in top mold frame, and the core rod is arranged in lower mold holder.
Further, the matrix is made using heated die steel, and the core rod is made using wolfram steel.
Further, the external diameter of the core rod is more than the external diameter of a circle of hexagon die cavity.
Further, the outer wall of the matrix is in up big and down small conical surface shape.
The utility model has an advantageous effect in that：Mould is divided into matrix and core rod by the utility model, and core rod is outer
Footpath is more than the external diameter of a circle of hexagon die cavity, and during hot pier, the bottom of whole hexagon die cavity is in the top of core rod
In the range of face, the top surface of the core rod made by wolfram steel using wolfram steel high rigidity and high intensity, can be carried effectively come the power that withstands shocks
High life；And the utility model is split type, can be changed at any time after a portion damage, and without changing whole mould
Tool, has saved cost, simple in construction, easy to use.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the present utility model.
Fig. 2 is the overlooking the structure diagram of matrix.
Fig. 3 is the structural representation of high-strength bolt.
Embodiment
With reference to Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
A kind of combined type mould of high-strength bolt turret head as shown in Fig. 1 to Fig. 3, including one have hexagon type
The matrix 4 of chamber 6 and the core rod 2 with cylindrical mold cavity, matrix is coaxially arranged with core rod, and a counterbore 5 is formed with the top of core rod,
The top sides edge of cylindrical mold cavity is arc port (being formed by rounding).
(outer wall of the matrix is in up big and down small conical surface shape, is easy to tear open in top mold frame 3 for the matrix insertion
Unload), the core rod insertion is arranged in lower mold holder 1.The matrix is made using heated die steel, and the core rod is made using wolfram steel.
The external diameter of the core rod is more than the external diameter of a circle of hexagon die cavity, is withstood shocks by the top surface of the core rod of wolfram steel making
Power.Top mold frame uses common iron with lower mold holder.It is bolted between top mold frame and lower mold holder, in order to avoid hot pier time shift
Position.Have in Fig. 3, blank 8, turret head 7.
Preferred embodiment of the present utility model is the foregoing is only, for those skilled in the art, this practicality is new
Type can have various modifications and variations.All any modifications within the spirit and principles of the utility model, made, equally replace
Change, improve, should be included within the scope of protection of the utility model.
