Abstract
The utility model relates to a rubber injection die and discloses a die structure preventing engine oil filter screen rubber from being overflowed during vulcanization and moulding. The die structure comprises a material injecting plug, a material injecting cavity and a bottom die, wherein the material injecting plug is positioned on the material injecting cavity and presses the material injecting cavity; a filter screen is arranged between the material injecting cavity and the bottom die; a groove is formed on the material injecting cavity; a spring is arranged in the groove; and the spring is pushed against the material injecting plug. The die structure has the beneficial effects that: a rubber flash condition generated on the surface of the filter screen after a product is vulcanized is effectively avoided by adding the spring and a lug boss on a traditional die.
Description
Technical field
The utility model relates to rubber injection mold, relates in particular to a kind of mould structure that prevents the excessive glue of oil filter screen rubber curing forming.
Background technology
The extensive sulfurizing mould structure that adopts of the product of oil filter screen rubber curing forming is made up of material feeding plug, injection pot and bed die at present.Generally metal screen is put into mold bottom die, the injection pot that closes is then put into block rubber in injection pot, the material feeding plug closes, starting device applies notes pressure to the material feeding plug, and the rubber in the injection pot becomes flow-like under HTHP, and the injection eye by injection pot fills up mold cavity.Because when applying notes pressure, the metal screen surface is not pushed down by injection pot and bed die plane, so the defective that exists of mould structure is that rubber can overflow from the metal screen surface when annotating pressure applying, on screen surface, can't clean out, influence the product filter effect.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of mould structure that prevents the excessive glue of oil filter screen rubber curing forming, solves and annotates the problem that rubber can overflow from the screen pack surface when pressing in the prior art.
The utility model provides a kind of mould structure that prevents the excessive glue of oil filter screen rubber curing forming, comprise material feeding plug, injection pot and bed die, described material feeding plug is positioned on the described injection pot and pushes down described injection pot, be provided with screen pack between described injection pot and described bed die, described injection pot is provided with groove, in the described groove spring is installed; Described spring is replaced described material feeding plug.
As further improvement of the utility model, be respectively equipped with boss on the last plane of the bottom of described injection pot and bed die, described screen pack is placed on the described boss.
As further improvement of the utility model, described boss is the 0.2mm height.
As further improvement of the utility model, described groove is four described grooves, in each described groove a spring is installed respectively.
The beneficial effects of the utility model are: by on existing mold, increasing spring and boss, effectively prevented vulcanizate after screen surface produce rubber burrs.
[description of drawings]
Fig. 1 is the structural representation that the utility model prevents the mould structure of the excessive glue of oil filter screen rubber curing forming.
[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
A kind of mould structure that prevents the excessive glue of oil filter screen rubber curing forming, comprise material feeding plug, injection pot and bed die, described material feeding plug is positioned on the described injection pot and pushes down described injection pot, be provided with screen pack between described injection pot and described bed die, described injection pot is provided with groove, in the described groove spring is installed; Described spring is replaced described material feeding plug.
Be respectively equipped with boss on the last plane of the bottom of described injection pot and bed die, described screen pack is placed on the described boss.
Described boss is the 0.2mm height.
Described groove is four described grooves, in each described groove a spring is installed respectively.
In one embodiment, as Fig. 1, a kind of mould structure that prevents the excessive glue of oil filter screen rubber curing forming, comprise material feeding plug 1, injection pot 2 and bed die 3, described material feeding plug 1 is positioned on the described injection pot 2 and pushes down described injection pot 2,3 of described injection pot 2 and described bed dies are provided with screen pack 33, and described injection pot 2 is provided with groove, and spring 21 is installed in the described groove; Described spring 21 is replaced described material feeding plug 1, in the present embodiment, increase by 4 springs on the injection pot, be respectively equipped with boss 34 on the last plane of the bottom of described injection pot 2 and bed die 3, the height of this boss is 0.2mm, and described screen pack 33 is placed on the described boss 34.During use metal screen is put into mold bottom die, the injection pot that closes is then put into block rubber 32 in injection pot, the material feeding plug 1 that closes, and starting device applies notes pressure to material feeding plug 1.Owing on the injection pot 1 spring 21 is arranged, apply when annotating pressure, spring 21 will be annotated pressure and hand on, and make the boss 34 on injection pot 2 and the bed die 3 push down screen surface, eliminate the gap of metal screen and injection pot and bed die.Just before the rubber injecting glue, filter screen is sealed, and with the increase of the pressure of showwing loving care for, the rubber in the injection pot becomes flow-like under HTHP, and the injection eye 31 by injection pot fills up mold cavity, and rubber can not overflow and stick to screen surface like this.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
