Description
Technical field
The present invention relates to rubber ring production technical fields, and in particular to a kind of rubber loop mould.
Background technology
Mold be in industrial production to be molded, be blow molded, squeeze out, the side such as die casting or forging forming, smelting, punching press, stretching
Method obtains the tool of required product.With the fast development of high molecular material, rubber mold is closely related with people’s lives, root
According to a variety of different demands, the rubber ring of small line footpath specification is widely used in various occasions.But existing old small line footpath round
Female mold tool structure, in discharge, rubber size is not easy to be discharged into mold cavity, and operator discharge velocity is slow, easily causes dead
Material, misrun, choke with resentment it is bad.The dead material i.e. overlong time of accurate discharge in mold cavity leads to sizing material heated time on mold
It grows and generates incipient scorch, product is caused extremely to expect；Misrun, that is, sizing material is not easy equably to be booked mold cavity, and especially sizing material is heated rear variable
Shape cannot fill mold cavity well, cause product misrun；I.e. sizing material some places of choking with resentment cover mold cavity, type completely
Gas inside chamber is difficult to exclude, bad to cause product to choke with resentment.Forming quality of products is poor, cannot be satisfied requirement；
Production efficiency is relatively low simultaneously, cannot be satisfied the production requirement of enterprise.
Invention content
In view of this, the object of the present invention is to provide a kind of rubber loop mould, to improve the molding matter of rubber ring product
Amount and production efficiency.
The present invention is solved the above problems by following technological means：A kind of rubber loop mould, including formation die core, it is described at
Pattern in-core offers cavity, and open top is offered at the top of formation die core and is delayed by the material that feeding-passage is connected to cavity
Rush chamber, the material buffer intracavitary is provided with seals the pressing plate being slidably connected with material buffer chamber, the pressing plate by tension spring with
Material buffer bottom of chamber portion connects.
Further, the suction channel vertically extended is offered in the formation die core, the suction channel passes through
Exhaust passage is connected to cavity, and the junction of the exhaust passage and cavity is provided with filtering baffle, is provided in suction channel
Piston, formation die core top are provided with fixed pulley by holder, further include drawstring, described drawstring one end is connect with pressing plate, another
End is connect after bypassing fixed pulley with piston.
Further, the molding mold that the formation die core is made of upper mold and lower mold, the cavity of the upper mold
It is symmetrical arranged with the cavity of lower mold or the formation die core is a single mode mold for carrying concavity cavity.
Further, the cavity of the upper mold is formed in the lower surface of the upper mold, and the cavity of the lower mold is formed
In the upper surface of the lower mold.
Further, the upper mold is fitted together with the lower mold using the positioning of guide post guide sleeve fit system.
Further, the platen edge is arranged with rubber ring.
Beneficial effects of the present invention：The rubber loop mould of the present invention, including formation die core offer in the formation die core
Cavity, the material buffer chamber that formation die core top offers open top and is connected to cavity by feeding-passage, the material
It is provided in cushion chamber and seals the pressing plate being slidably connected with material buffer chamber, the pressing plate passes through tension spring and material buffer bottom of chamber portion
Connection.The rubber loop mould of the structure solves the problems, such as that rubber loop mould discharge stability is poor, it is dead to effectively prevent rubber
Material, is choked with resentment phenomena such as bad at misrun, and the Forming Quality and production efficiency of rubber ring product are improved.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the present invention.
Specific implementation mode
Below with reference to attached drawing, the present invention is described in detail, as shown in Figure 1：The rubber loop mould of the present embodiment, packet
Include formation die core, offer cavity 2 in the formation die core, cavity is annular groove-shaped, formation die core be by upper mold 101 and under
The cavity of the molding mold that mold 102 forms, the cavity of the upper mold and lower mold is symmetrical arranged or the formation die core
It is a single mode mold for carrying concavity cavity, in the present embodiment, molding that formation die core is made of upper mold and lower mold
Mold, the cavity of upper mold and the cavity of lower mold are symmetrical arranged, and the cavity of upper mold is formed in the lower surface of upper mold, lower die
The cavity of tool is formed in the upper surface of lower mold, and upper mold is assembled in one with lower mold using the positioning of guide post guide sleeve fit system
It rises；The material buffer chamber 3 for offering open top at the top of formation die core and being connected to cavity by feeding-passage, the material are slow
It rushes intracavitary and is provided with the pressing plate 4 being slidably connected with the sealing of material buffer chamber, the pressing plate passes through tension spring 5 and material buffer bottom of chamber portion
Connection.In forming process, material is initially injected material buffer chamber by corresponding injection-moulding device, then passes through feeding-passage again
Cavity is flowed into, during material injects cavity by material buffer chamber, tension spring tenses pressing plate, and pressing plate is made to be pressed down against always
Trend be conducive to improve material and enter the rate and uniformity of cavity to form extruding force to material in real time, solve rubber
The problem of cushion rubber mold discharge stability difference, effectively prevents rubber and extremely expects, misrun, chokes with resentment phenomena such as bad, improves rubber ring
The Forming Quality and production efficiency of product.
It is further improved as to above-mentioned technical proposal, the pumping vertically extended is offered in the formation die core
Channel 6 is inhaled, the suction channel is connected to by exhaust passage 7 with cavity, and the junction of the exhaust passage and cavity is provided with
Filtering baffle 8, filtering baffle are avoided that liquid rubber fluid flows into exhaust passage, piston 9, shaping mould are provided in suction channel
Fixed pulley 11 is provided with by holder 10 at the top of core, further includes drawstring 12, described drawstring one end is connect with pressing plate, and the other end bypasses
It is connect with piston after fixed pulley.As material gradually injects cavity, pressing plate gradually moves down, by drawstring pull piston gradually on
It moves, to generate swabbing action, on the one hand, the air in material or in cavity can be extracted out, further avoid phenomenon of choking with resentment；
On the other hand, the flow velocity that can further increase material, makes material quickly fill with cavity, to improve production efficiency.
Be further improved as to above-mentioned technical proposal, the platen edge is arranged with rubber ring 13, rubber ring with open
It is located at the annular groove socket of platen edge, rubber ring has elasticity, the sealing between energy real-time ensuring pressing plate and material buffer chamber
Effect.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the right of invention.
