Description
Technical field
The utility model is related to die device technical field, and in particular to one kind is used to manufacture router face-piece and similar production
The mould of product.
Background technology
It is general by corresponding mould molding when manufacturing router face-piece and similar products, as shown in figure 5, such mould
The parts such as upper die and lower die, core rod 3A, thimble are generally included, the pan feeding portion 21A of mould passes through flow path portion 22A connection mouths of a river portion
25A, mouth of a river portion 25A connection core rods 3A forming cavity, and flow path portion end 23A connection mouths of a river portion 25A mouth of a river radical end 24A,
And mouth of a river radical end 24A diameter is more than flow path portion end 23A diameter, the diameter of mouth of a river portion end is less than mouth of a river radical end
Mouth of a river thimble 5A is provided with below 24A diameter, mouth of a river portion.That is, the mouth of a river section head end of the mould is than flow channel section end more
Slightly, the shortcoming of this structure is that after shaping terminates, upper and lower mould is separated, the regrinding-material of flow channel section end（That is flow path portion end
23A）Directly it is pulled off, but the regrinding-material of mouth of a river section（That is mouth of a river portion 25A）Need thimble 5A tops in the mouth of a river are disconnected can take out of, cause mould
The structure of tool is more complicated, and shaping efficiency is relatively low, and this structure needs larger briquetting pressure, and the requirement to injection machine is more
Height, so as to produce higher production cost.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of structure design more rationally, production efficiency is higher, structure
The lower face-piece class product forming mould improved structure of simpler, required briquetting pressure.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：A kind of face-piece class product forming mould
Improved structure, includes upper die and lower die and core rod, and core rod is installed in lower mould, is located at after formed product on core rod, upper mould position
On lower mould, there is feeding mechanism in upper mould, feeding mechanism is from upper mould insertion into core rod, and moulding process stem stands on production
On product, it is characterised in that：The feeding mechanism includes pan feeding section, flow channel section and mouth of a river section, flow channel section access material section, mouth of a river section
Flow channel section is connect, pan feeding section forms pan feeding portion, and flow channel section formation flow path portion, mouth of a river section forms mouth of a river portion, wherein pan feeding section and runner
The main part of section is located in upper mould, and mouth of a river section is located in core rod and connects forming cavity；Flow channel section is diminishing structure, shape
Into flow path portion end diameter be less than its head end diameter；Mouth of a river section is also diminishing structure, the mouth of a river portion end of formation
Diameter be less than mouth of a river radical end diameter；Mouth of a river radical end is connected with flow path portion end, and the diameter at mouth of a river radical end is less than
The diameter of flow path portion end.
Further, the mouth of a river section is bending shape, and from mouth of a river section, head end is towards forming cavity linear narrowing and bends for it, this
Planting structure can enable regrinding-material during die sinking more all break.
Further, provided with two formed product chambers on core rod, each forming cavity respectively connects mouth of a river section, two mouths of a river section
It is connected respectively by its corresponding flow channel section with the two ends of pan feeding section, the uniformity that so can more keep material to enter, and die sinking
When can together be pulled out with both sides regrinding-material.
After shaping terminates, upper and lower mould is separated, mouth of a river portion end the pulling to leave behind and directly break simultaneously in flow path portion of mouth of a river section
It is carried over.
The utility model is by the way that the feeding structure part of face-piece class product forming mould is improved, i.e., by traditional moulds
The middle mouth of a river section head end structure thicker than flow channel section end, it is thinner than flow channel section end to be changed to mouth of a river section head end, and from flow channel section
Head end toward mouth of a river section end to reduce the structure attenuated always, and this structure mainly has following two advantages, first, mouth of a river portion
Can be with pan feeding portion with flow path portion（I.e. whole regrinding-material）It can together break and take out of, without disconnected with thimble top, so as to save
Province mouth of a river thimble, simplifies the structure of mould；Second, because the passage of whole pan feeding is the structure that tapers into, can significantly it drop
The pressure of low shaping, the requirement to injection machine can accordingly be reduced, and reduce production cost.
