Abstract
The utility model discloses a sprue-free O-shaped ring injection mould, which comprises a moving mould and a fixed mould, wherein the moving mould is provided with a first material bin; the first material bin is provided with a lower cavity; the fixed mould is provided with a second material bin; the second material bin is provided with an upper cavity matched with the lower cavity; and the lower cavity and the upper cavity form an integral vacuum cavity after the moving mould and the fixed mould are combined. The sprue-free O-shaped ring injection mould also comprises a vacuum pump, wherein the vacuum pump is connected with the moving mould; the moving mould is provided with a plurality of lower cavities; and the fixed mould is provided with upper cavities matched with the lower cavities. For the sprue-free O-shaped ring injection mould, the vacuum pump is utilized to pump air to ensure that the sealed vacuum cavity is formed after the moving mould and the fixed mould are combined, so that bubbles can not be generated in the cavity; and the O-shaped ring is not provided with the sprue, so that the sealing performance is guaranteed.
Description
Technical field
The utility model relates to mould manufacturing field, particularly a kind of no cast gate injection mold of making O type circle.
Background technology
The O RunddichtringO is to use very many a kind of seals in hydraulic pressure and the pneumatic actuator system, and injection moulding O RunddichtringO is injection molded through injection machine, and existing O type circle injection mold all has the injection moulding cast gate; After the demoulding; Can residual injection moulding cast gate on the product, influence the sealing function of product, particularly for the O type circle of some small dimension sizes; Example: the line footpath is less than the O type circle of 3.53mm, and cast gate can directly cause the sealing property of product to lose efficacy.
The utility model content
In order to address the above problem, the utility model provides a kind of no cast gate O type circle injection mold, comprises dynamic model and cover half; Dynamic model is provided with first material bin, and first material bin is provided with lower impressions, and cover half is provided with the terrium quid feed bin; The terrium quid feed bin is provided with the upper impression that cooperates with lower impressions; Dynamic model and cover half merge the back lower impressions and upper impression forms a complete vacuum die cavity, also comprises vavuum pump, and vavuum pump is connected with dynamic model.
Said dynamic model is provided with a plurality of lower impressions, and cover half is provided with a plurality of upper impression that cooperate with lower impressions.
Said dynamic model is provided with jacking block, and cover half is provided with injection hole.
The junction of said die cavity and material bin is provided with chamfering.
Advancing the glue mode is that glue is advanced on whole plane, replaces habitual some cast gate and advances glue.
The utility model stops when dynamic model and cover half are incorporated into certain distance, at this moment starts vavuum pump, vacuumizes the vacuum die cavity that dynamic model and cover half is incorporated into fully form a sealing together; When vacuumizing, begin to inject melt from injection hole, the matched moulds of dynamic model and cover half and material feeding are carried out simultaneously, and utilizing the vavuum pump suction air to make in material bin and the die cavity does not have air; Make more even that melt distributes in die cavity; And can not produce bubble, guarantee the quality of product, the material after the demoulding is accomplished drawing on stamping machine; Because a lot of O type circles are arranged on the material; Utilize the clamps material, and on punch press, carry out punching press, higher than the manual press degree of single O type circle.
Utilize the O type circle of the utility model production not have cast gate, can well guarantee the sealing property of O type circle.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing
See also Fig. 1 to Fig. 6, a kind of no cast gate O type circle injection mold comprises dynamic model 3 and cover half 1; Dynamic model 3 is provided with first material bin, 24, the first material bins 24 and is provided with lower impressions 22, and cover half 1 is provided with terrium quid feed bin 23; Terrium quid feed bin 23 is provided with the upper impression 21 that cooperates with lower impressions 22, and dynamic model 3 merges back lower impressions 22 with cover half 1 and forms a complete O type circle die cavity 2 with upper impression 21, also comprises vavuum pump; Vavuum pump is connected with dynamic model; Dynamic model 3 is provided with jacking block 31, and cover half 1 is provided with injection hole 11, and said upper impression 21 is provided with chamfering 25 with the junction of last material bin 23.
The above-mentioned disclosed specific embodiment that is merely the utility model, this embodiment only are that clearer explanation the utility model is used, and are not the qualification to the utility model, any those skilled in the art can think variation, all should drop in the protection domain.
