Described rear mold die joint is provided with chute with described line position corresponding position, described line position is provided with draw runner and coordinates with described slide.
The die joint of described front mould is provided with shovel with described line position corresponding position.
On the die joint of described front mould, the end face corresponding position with described line position is provided with spring knock pin.
Described line position is additionally provided with handle on described chute direction.
The end of described chute is provided with baffle plate, and one end of described baffle plate and described rear mold are hinged.
The silicone filler end of described straight tube die cavity is provided with overflowing well.
The die joint both sides of described straight tube die cavity are provided with flash groove, and wherein the described flash groove of side is connected with the cold runner nozzle in described front mould by sub-runner.
The beneficial effects of the utility model are: include front mould and rear mold due to this utility model, described rear mold die joint is provided with straight tube core, constitute straight tube die cavity in described straight tube core corresponding position after described front mould and described rear mold matched moulds, the fixing end of described straight tube core is fixed in line position and by location and installation on described line position mould in the rear, described front mould and described rear mold are provided with supporting mechanism, the support pin of described supporting mechanism withstands described straight tube core, stretching for pneumatic control of described support pin between two relatively.So by the multipoint positioning of described line position and the described support pin of pneumatic control and clamping, described straight tube core is made to reduce cantilever deflection in injecting glue process, counteract the impact impact of injecting glue extruding force, the axiality of described straight tube core Yu described straight tube die cavity is controlled in smaller range, make product uniform wall thickness, reach high-precision requirement, in injecting glue process, when namely injecting glue amount will be filled with described straight tube die cavity, described supporting mechanism passes through pneumatic control, described support pin is regained, silica gel material is made to be filled by the original position of described support pin, so that described straight tube die cavity can be filled up completely with, do not affect the physical dimension of product.

Detailed description of the invention
Such as Fig. 1, shown in Fig. 2 and Fig. 3, in the present embodiment, described a kind of silica gel sealing straight tube mould includes front mould 1 and rear mold 2, described rear mold 2 die joint is provided with straight tube core 3, constitute straight tube die cavity 4 in described straight tube core 3 corresponding position after described front mould 1 and the 2-in-1 mould of described rear mold, the fixing end of described straight tube core 3 is fixed in line position 5 and by location and installation on described line position 5 mould 2 in the rear, described front mould 1 and described rear mold 2 are provided with supporting mechanism, the support pin 6 of described supporting mechanism withstands described straight tube core 3 between two relatively, stretching for pneumatic control of described support pin 6.By the multipoint positioning of described line position 5 and the described support pin 6 of pneumatic control and clamping, described straight tube core 3 is made to reduce cantilever deflection in injecting glue process, counteract the impact impact of injecting glue extruding force, the axiality of described straight tube core 3 with described straight tube die cavity 4 is controlled in smaller range, make product uniform wall thickness, reach high-precision requirement, in injecting glue process, when namely injecting glue amount will be filled with described straight tube die cavity 4, described supporting mechanism passes through pneumatic control, described support pin 6 is regained, silica gel material is made to be filled by the original position of described support pin 6, so that described straight tube die cavity 4 can be filled up completely with, do not affect the physical dimension of product.
In the present embodiment, described rear mold 2 die joint is provided with chute 21 with described line position 5 corresponding position, described line position 5 is provided with draw runner 51 and is slidably matched with described chute 21.After die sinking, in knockout course, owing to the slenderness ratio of described straight tube core 3 is bigger, described straight tube core 3 is made to be easy to cause deformed damaged because the die joint with described rear mold 2 collides, therefore be slidably matched described in passing through and make described line position 5 drive described straight tube core 3 to further take out after skidding off described straight tube die cavity 4 along described chute 21 by described draw runner 51 so that described straight tube core 3 is not easily susceptible to collision deformation.
In the present embodiment, the die joint of described front mould 1 being provided with shovel 11 with described line position 5 corresponding position, described shovel 11 holds out against with described line position 5 and coordinates.When matched moulds, described shovel 11 props up described line position 5 below in described line position 5, it is prevented that during injecting glue, described line position 5 produces to retreat displacement because being subject to the pressure of injecting glue, and then has influence on the size of product, so described shovel 11 plays the effect locking described line position 5.
In the present embodiment, the die joint of described front mould 1 is provided with spring knock pin 12 with the end face corresponding position of described line position 5, after matched moulds, the end face compression fit of described spring knock pin 12 and described line position 5.Ensure that the fixing of described line position 5 and be accurately positioned.
In the present embodiment, described line position 5 is additionally provided with handle 52 on described chute 21 direction.Due to the thermosetting of silica gel material, sulfidation needs higher temperature so that the temperature of described a kind of silica gel sealing straight tube mould is higher, therefore be provided with the convenient operator's taking when the demoulding of described handle 52.
In the present embodiment, the end of described chute 21 is provided with baffle plate 22, and one end of described baffle plate 22 and described rear mold 2 are hinged.During die sinking, 22 position-limiting actions of described baffle plate, it is to avoid described line position 5 skids off described chute 21.
In the present embodiment, the silicone filler end of described straight tube die cavity 4 is provided with overflowing well 41, and the die joint both sides of described straight tube die cavity 4 are provided with flash groove 42, and wherein the described flash groove 42 of side is connected with the cold runner nozzle 13 in described front mould 1 by sub-runner.The problem being effectively improved the product burr of injecting glue aerofluxus.
This utility model is applied to the technical field of silica gel sealing straight tube mould.
Although embodiment of the present utility model describes with practical solution, but it is not intended that the restriction to this utility model implication, for those skilled in the art, the combination according to this specification amendment to its embodiment and with other schemes will be apparent from.
