Specific embodiment
In the following, technical solution of the present invention is described in detail by specific embodiment.
As shown in Figure 1-3, Fig. 1 is a kind of structural representation of the O-ring seal mold of injection pressure formula structure proposed by the present invention
Figure；Fig. 2 is the structural schematic diagram of cope plate described in a kind of O-ring seal mold of injection pressure formula structure proposed by the present invention；Fig. 3
For the structural schematic diagram of lower template described in a kind of O-ring seal mold of injection pressure formula structure proposed by the present invention.
Referring to Fig.1-3, a kind of O-ring seal mold for injection pressure formula structure that the embodiment of the present invention proposes, comprising: upper and lower cloth
The cope plate 1 and lower template 2 set, in which:
Cope plate 1 is equipped with several shapes close to the side of lower template 2 as circular upper region, and region on any one
Inside it is equipped with several upper cavities 11；On any one in region in upper cavity 11 on this in region in round pie arrange,
Each upper cavity 11 on any one in region is interconnected；Side of the cope plate 1 far from lower template 2 and be located at any one on
The glue injection channel 12 with regional connectivity on this is equipped with above region；Lower template 2 close to cope plate 1 side and be located at any
Being equipped with a corresponding and shape below one upper region is circular lower region, is equipped in any one lower region
Several lower mode cavities 21, the lower mode cavity 21 under any one in region and the number of upper cavity 11 in upper region corresponding to the lower region
Amount is consistent and successively corresponds；In any one lower region and it is located at the periphery of all lower mode cavities 21 equipped with around all lower mode cavities
21 overflow launders being circular layout, the overflow launder is by the connected component slot in mesh arrangement and near the one of the overflow launder inner peripheral surface
Lower mode cavity 21 is enclosed to be connected to；And under molding state, upper cavity 11 and lower mode cavity 21 complement each other to form type chamber, in injecting glue state
Under, the spacing of 2~3mm is reserved between cope plate 1 and lower template 2.
In the present embodiment, any one upper cavity on any one in region respectively by connectivity slot with it is adjacent upper
Die cavity connection；Being provided with for the structure is conducive to further shorten the injecting glue time, and further increases the uniformity of overlap thickness.
In the present embodiment, upper region is arranged in array on cope plate 1, and in lower template 2 and is located at the two of arbitrary neighborhood
Clout slot 22 is equipped between row or the lower region of two column, which arranges the overflow in lower region with adjacent two rows or two respectively
Slot connection；The setting of clout slot, first is that product and waste material is facilitated to take out together；Second is that the dumping time can be shortened, to improve life
Produce efficiency；Third is that the product in each region can be connected it is integral, for the glue of some easy sticking to moulds while facilitating feeding
Expect available effective control.
In another embodiment, clout slot 22 can also be arranged between two lower regions of arbitrary neighborhood.
The present invention substitutes original compression molding mode using injection moulding, it is no longer necessary to using auxiliary mould (as fed
Device), to save cost and non-cutting time；And partition domain is distributed die cavity and makes same area in the upper and lower template in the present invention
The characteristic that various chamber in domain communicates with each other, accelerates injecting glue efficiency, so that the formed product time is short, so that production efficiency is able to
It greatly improves, and feeding is convenient, meanwhile, the characteristic that partition domain is distributed die cavity and the various chamber in the same area is made to communicate with each other,
And the sizing material infused is in a molten state, so that overlap thickness tends to uniformly, the utilization rate of sizing material effectively improves, and netted
The setting of connected component slot is then conducive to further shorten the discharge time；In addition, type chamber is arranged in region in round pie in the present invention
Cloth, can be convenient rear road is punched product overlap with fixture, eliminates the manually deflashing or costly of most original
Freeze deflashing.Its specific works of the invention are as follows:
It first controls cope plate 1 and lower template 2 enters injecting glue state, make to reserve 2~3mm's between cope plate 1 and lower template 2
Spacing, then by material feeding in the upward region of glue injection channel, institute's injecting glue material is branched to various intracavitary respectively by connectivity slot, and is worked as
When sizing material between cope plate 1 and lower template 2 reaches a certain amount of, stop injecting glue, cope plate 1 and lower template 2 mold, shaped article.
