Abstract
The utility model provides a bellows class product rubber mold, includes mould and lower mould, goes up mould and lower mould opposite face and is equipped with the die cavity, is equipped with the core in the die cavity, forms the product outline during die cavity and core compound die, the product outline includes bellows section, characterized by: the upper die is characterized in that a sprue is arranged on the upper surface of the upper die, a longitudinal runner communicated with the sprue is arranged on the upper die, a transverse runner is arranged on the joint surface of the upper die and the lower die and communicated with the corrugated pipe section and the longitudinal runner, and a material equalizing groove with the width larger than that of the transverse runner is arranged in the middle of the transverse runner. This scheme provides a bellows class product rubber mold, and bellows department cavity can form the even product ripple surface of density.
Description
Technical field
This utility model relates to injection mold, particularly to a kind of corrugated tube series products rubber mold.
Background technology
Ripple pipe part has a circle circle annular ridge due to surface alignment so that pipe fitting is easier to bending and high resilience.When this series products of injection moulding, the material homogeneity of molding round fin is required very strict, not so after molding annular ridge due to each position anti-pressure ability different, it is easy to occur that local fatigue damages.
Utility model content
The purpose of this utility model is in that to provide a kind of corrugated tube series products rubber mold, and corrugated tube place chamber can form the uniform product corrugated surface of consistency.
Above-mentioned purpose of the present utility model has the technical scheme that a kind of corrugated tube series products rubber mold, including upper die and lower die, upper die and lower die opposite face is provided with die cavity, core it is provided with in die cavity, product outline is formed when die cavity and core matched moulds, described product outline includes bellows piece, described upper mould upper surface is provided with cast gate, upper mould is communicated with longitudinal runner of cast gate, the land area of upper mould and counterdie is provided with transverse flow channels, transverse flow channels diaphragm for passageway section and longitudinal runner, the width equal hopper more than transverse flow channels it is provided with in the middle part of transverse flow channels.
By adopting technique scheme, equal hopper becomes big due to width, melt flow is slowed down, certain retardance can be formed time again with the transverse flow channels communicating downstream narrowed, generation backflow effect so that melt forms backflow whirlpool in equal hopper, is stirred further by injection molding raw material, make to enter finally into the melt mixed of bellows piece evenly, form the uniform product corrugated surface of consistency.
Preferably, the degree of depth of equal hopper is more than transverse flow channels.
By adopting technique scheme, expand after the degree of depth so that melt is not only limited only to the stirring in horizontal plane in equal hopper, more can roll up and down, mixing more abundant.
Preferably, equal hopper is square.
By adopt technique scheme, square groove be prone to processing, and with transverse flow channels produce hierarchic structure cross ferry, bigger backflow power can be produced, be more conducive to mix homogeneously.
Preferably, described counterdie is provided with the cooling port coaxial with longitudinal runner, and the junction of transverse flow channels and longitudinal runner is positioned at cooling port upper end.
By adopting technique scheme, cooling port is used for storing the material that first wave is come in, and owing to runner does not warm up completely at that time, the material just come in is easily because temperature cools down not, and cooling port can collect the defect material of this some effects product quality.
Preferably, described longitudinal runner bottom is provided with enlarging.
By adopting technique scheme, owing to longitudinal runner and transverse flow channels exist the flex point of 90 degree, enlarging is set and can slow down flow velocity, reduce the impact in melt convection road.
In sum, this utility model has the advantages that forming quality of products is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of corrugated tube series products rubber mold, including upper mould (1) and counterdie (2), upper mould (1) and counterdie (2) opposite face are provided with die cavity, core it is provided with in die cavity, product outline is formed when die cavity and core matched moulds, described product outline includes bellows piece (3), described upper mould (1) upper surface is provided with cast gate (4), upper mould (1) is communicated with longitudinal runner (5) of cast gate (4), the land area of upper mould (1) and counterdie (2) is provided with transverse flow channels (6), transverse flow channels (6) diaphragm for passageway section (3) and longitudinal runner (5), transverse flow channels (6) middle part is provided with the width equal hopper (8) more than transverse flow channels (6).Equal hopper (8) becomes big due to width, melt flow is slowed down, certain retardance can be formed time again with transverse flow channels (6) communicating downstream narrowed, generation backflow effect, melt is made to form backflow whirlpool in equal hopper (8), injection molding raw material is stirred further so that enter finally into the melt mixed of bellows piece (3) evenly, form the uniform product corrugated surface of consistency.
As shown in Figure 4, the degree of depth of equal hopper (8) is more than transverse flow channels (6).Expand after the degree of depth so that melt is not only limited only to the stirring in horizontal plane in equal hopper (8), more can roll up and down, mixing more abundant.Equal hopper (8) is for square.Square groove be prone to processing, and with transverse flow channels (6) produce hierarchic structure cross ferry, bigger backflow power can be produced, be more conducive to mix homogeneously.
As it is shown on figure 3, counterdie (2) is provided with the cooling port (7) coaxial with longitudinal runner (5), the junction of transverse flow channels (6) and longitudinal runner (5) is positioned at cooling port (7) upper end.Cooling port (7) is used for storing the material that first wave is come in, and owing to runner does not warm up completely at that time, the material just come in is easily because temperature cools down not, and cooling port (7) can collect the defect material of this some effects product quality.
As it is shown in figure 5, longitudinal runner (5) bottom is provided with enlarging (9).Owing to longitudinal runner (5) and transverse flow channels (6) exist the flex point of 90 degree, enlarging (9) is set and can slow down flow velocity, reduce the impact in melt convection road.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
