Abstract
The present invention discloses a kind of flexible glue flash structure, for including the product in ebonite portion and flexible glue portion, has through-hole in the ebonite portion, the flexible glue portion, which has, is inserted in the through-hole and the boss by exposing surface, which includes: ejection part, set on the lower section of the product；Flash groove, set on the side of the ejection part, the flash groove is located at below the boss；Air discharge duct, set on the side of the ejection part, the air discharge duct, which extends, to be set to below the flash groove.Compared to the prior art, flexible glue flash structure of the invention, due to being just directly to be taken the flash remained in flash groove out of after formed product using ejection part, when therefore forming next product again, flexible glue will not be remained in mold, the problem of will not blocking, be conducive to be vented, avoiding frequent demoulding cleaning flexible glue flash.
Description
[technical field]
The present invention relates to a kind of plastic moulds, and in particular to a kind of flexible glue flash structure.
[background technique]
It for the product that flexible glue and ebonite combine, is carried out using the molding mode of dijection, second penetrates mold combines in flexible glue
Flexible glue flash structure can be done at line.
Referring to Fig. 1, Fig. 1 is schematically shown as a kind of flexible glue flash structural schematic diagram of the prior art.As shown, product includes
Ebonite portion 100 and flexible glue portion 200 have through-hole 101, the corresponding through-hole 101 tool in the flexible glue portion 200 in the ebonite portion 100
There is boss 201, which is inserted in the through-hole 101 and exposing surface, when which forms with the through-hole 101
It is combined with each other.
The flash structure of the prior art includes one entering son 300, it is described enter sub 300 sides there is flash groove 301 and air discharge duct
302, the flash groove 301, which extends, is set to 201 lower section of boss, and the air discharge duct 302, which extends, to be set under the flash groove 301
Side.
However, due to being used into son 300, the flexible glue of flash can break in flash groove after molding using above-mentioned flash structure
In 301, lead to trapped gas, gas row does not go out to influence product quality, customer demand is not achieved, and then need to clear up after mould release
Remaining flash.
In view of this, it is really necessary to develop a kind of flexible glue flash structure, to solve the above problems.
[summary of the invention]
Therefore, the purpose of the present invention is to provide a kind of flexible glue flash structures, and flexible glue overflows after solving existing flash shaping structures
Material remains in mold, subsequent forming can not normal exhaust the problem of.
In order to achieve the above object, flexible glue flash structure of the invention, for including the product in ebonite portion and flexible glue portion, institute
Stating has through-hole in ebonite portion, the flexible glue portion, which has, is inserted in the through-hole and the boss by exposing surface, which includes:
Ejection part, set on the lower section of the product；
Flash groove, set on the side of the ejection part, the flash groove is located at below the boss；
Air discharge duct, set on the side of the ejection part, the air discharge duct, which extends, to be set to below the flash groove.
Optionally, the ejection part is taper pin or jacking block.
Optionally, the flash groove is wide at the top and narrow at the bottom, and section is trapezoidal.
Optionally, the upper end width of the flash groove is 0.07 millimeter -0.09 millimeter.
Optionally, the upper end width of the flash groove is 0.08 millimeter.
Optionally, the lower end width of the flash groove is 0.01 millimeter -0.03 millimeter.
Optionally, the lower end width of the flash groove is 0.01 millimeter.
Optionally, the section of the air discharge duct is rectangle.
Optionally, the width of the air discharge duct is 0.02 millimeter -0.03 millimeter.
Optionally, the width of the air discharge duct is 0.03 millimeter.
Compared to the prior art, flexible glue flash structure of the invention, due to just after formed product using ejection part
The flash remained in flash groove is directly taken out of, therefore when forming next product again, will not remain flexible glue in mold, will not
The problem of blocking, be conducive to be vented, avoiding frequent demoulding cleaning flexible glue flash.
[Detailed description of the invention]
Fig. 1 is schematically shown as a kind of flexible glue flash structural schematic diagram of the prior art.
Fig. 2 is painted the structural schematic diagram of one preferred embodiment of flexible glue flash structure of the invention.
Fig. 3 is painted the partial enlargement structural representation of one preferred embodiment of flexible glue flash structure of the invention.
[specific embodiment]
Fig. 2, Fig. 3 are please referred to, Fig. 2 is painted the structural representation of one preferred embodiment of flexible glue flash structure of the invention
Figure, Fig. 3 are painted the partial enlargement structural representation of one preferred embodiment of flexible glue flash structure of the invention.
In order to achieve the above object, flexible glue flash structure of the invention, for including the production in ebonite portion 10 and flexible glue portion 20
Product have through-hole 11 in the ebonite portion 10, and the flexible glue portion 20, which has, is inserted in the through-hole 11 and the boss by exposing surface
21, which includes:
Ejection part 30, set on the lower section of the product；
Flash groove 31, set on the side of the ejection part 30, the flash groove 31 is located at 21 lower section of boss；
Air discharge duct 32, set on the side of the ejection part 30, the air discharge duct 32, which extends, is set to 31 lower section of flash groove.
Compared to the prior art, flexible glue flash structure of the invention, due to be using ejection part 30 after formed product just
When the flash remained in flash groove 31 directly being taken out of, therefore forming next product again, flexible glue will not be remained in mold,
The problem of will not blocking, be conducive to be vented, avoiding frequent demoulding cleaning flexible glue flash.
Wherein, the ejection part 30 can be taper pin or jacking block, depending on specific mould structure and product structure.
Wherein, the flash groove 31 can be wide at the top and narrow at the bottom, and section is trapezoidal.The wider suitable flash in upper end enters, lower end
It is relatively narrow to can control flash downlink, it is ensured that gas can be discharged.
Wherein, the upper end width of the flash groove 31 can be 0.07 millimeter -0.09 millimeter, the width be suitble to flash into
Enter.Preferably, the upper end width of the flash groove 31 is 0.08 millimeter.
Wherein, the lower end width of the flash groove 31 can be 0.01 millimeter -0.03 millimeter, which is conducive to control and overflows
