Description
Technical field
The utility model relates to sealing element processing technique field, especially a kind of accurate brass seal molding die.
Background technique
In the prior art, for one end periphery injection molded elastomer that accurate brass seal is in brass part, when use, can be close
Envelope.The shape of brass part is as shown in Figure 1, the shape of brass seal is as shown in Figure 2.At present in the peripheral injection molded elastomer of brass part
In the process, it is easy to appear in the shrinkage pool of brass part and enters rubber, to influence the normal use of brass seal, form substandard products.
In addition the independent die cavity of current brass seal typically one by one is formed, and shaping efficiency is low.
Utility model content
It is simple that a kind of structure is provided purpose of the utility model is to solve the deficiency of above-mentioned technology, can ensure that brass
Sealing element quality and the accurate brass seal molding die for promoting processing efficiency.
In order to achieve the above object, a kind of precision brass seal molding die designed by the utility model, including under
Mould, middle mould and upper mold, lower die are slab construction, and the upper surface of lower die is provided with concave cavity, and the bottom surface of inner cavity is level,
What is be spaced on the bottom surface of indent is provided with several brass part placed cavities, and the lower surface of the middle mould is planar structure,
The upper surface of middle mould is recessed downwards sizing material chamber, is provided at position corresponding with brass part placed cavity on middle mould logical
Hole, is arranged mold core in through-hole, and the lower end surface of the mold core is docked with the brass part being located in brass part placed cavity by brass
Shrinkage pool on part blocks, and blanking hole is provided on the middle mould between adjacent mold core, and blanking hole is connected to the concave cavity of lower die
With the sizing material chamber of middle mould；The lower end surface of upper mold is provided with the bulge-structure with the cooperation of sizing material chamber, and bulge-structure is used for sizing material chamber
Interior sizing material is pressed into the concave cavity and brass part placed cavity of lower die by blanking hole.
Above-mentioned technical proposal, brass part is placed on inside brass part placed cavity, mould when then covering middle mould, on middle mould
Core lower end surface and brass part cooperate, and the shrinkage pool of brass part is blocked, and place proper amount of sizing material the sizing material of middle mould is intracavitary, on
Sizing material out of blanking hole is pressed into concave cavity and is extended to the brass part placed cavity around brass part by pressurization after on die cap,
Sizing material in brass part placed cavity is connect with brass part in cooling procedure, forms brass seal；And the brass of multiple arrays
The film that sealing element and the concave cavity of lower die are formed links together, to demould simpler, can pass through the later period after demoulding
Separation, it is simple and convenient, and it is easy number of computations.After mold core and brass part cooperate simultaneously, it is avoided that sizing material enters brass part
In shrinkage pool, brass seal quality is effectively promoted.
The lower end diameter of blanking hole is less than the upper end diameter of blanking hole.The design of the structure, during demoulding, blanking hole
Interior sizing material is connect with the intracorporal sizing material of lower die inner cavity, and also the sizing material intracavitary with middle mould sizing material connects, straight due to lower end
Diameter is small, film separation that can directly with lower end in separation process, so that demoulding simpler convenience.
The bottom of brass part placed cavity is provided with dumping pit, dumping pit upper end is connected to brass part placed cavity, dumping pit
Lower end penetrate through lower die.The design of the structure, when have interfered between brass part and brass part placed cavity and be difficult to demould when,
It can be ejected by the dumping pit of lower section with pole, it is simple and convenient, brass seal will not be destroyed.
When the lower end surface of mold core and the shrinkage pool for the brass part being located in brass part placed cavity cooperate, the upper surface of mold core is higher than
The bottom surface of middle mould sizing material chamber.The design of the structure can give in concave cavity of the upper mold by the intracavitary sizing material indentation lower die of sizing material
Certain pressure, mold core is pressed in brass part with mold core, and sizing material is avoided to enter in the shrinkage pool of brass part, simple and convenient, is promoted
Quality.
A kind of obtained accurate brass seal molding die of the utility model, be able to achieve multiple brass parts once at
Type becomes brass seal and is connected on the same film, and demoulding etc. is easier；In addition the design of mold core can effectively be kept away
Exempt from sizing material to enter in the shrinkage pool of brass part, to promote the quality of brass seal.
