Abstract
The invention discloses a forming mold for a filter sealing ring, relates to the field of forming molds, and mainly solves the problems of the existing mold-formed sealing ring that the outer surface of the sealing ring has bumps and the surface quality is poor. The mold comprises a movable mold body, wherein a mold core body is arranged in the center of the mold body. The mold is characterized in that an injection molding hole is formed in the center of the mold core body; the injection molding hole is connected with a centrosymmetric flow path; and an inner injection molding hole is formed in the tail end of the flow path and is formed in the bottom of a mold cavity. The mold is simple in structure and reasonable in design, by injecting melt plastic into the mold cavity through the inner injection molding hole which is formed in the mold core body, the formed injection bumps are at the inner side of the formed sealing ring, the outer surface of the sealing ring is smooth, and the surface quality of the sealing ring is good.
Description
Technical field:
The present invention relates to a kind of mould, relate in particular to a kind of filter sealing ring mould.
Background technology:
Filter sealing ring all is to use the moulding of mould injecting glue at present, and the injecting hole operated by rotary motion of existing mould is on patrix, and after the sealing ring moulding, the salient point that the injecting hole place stays is at the outer surface of sealing ring, make the sealing ring outer surface rough smooth, affect the product appearance quality.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art, provides a kind of injecting hole to be arranged on filter sealing ring mould on the core rod body.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of filter sealing ring mould comprises mobile die body, and mobile die body mid portion is provided with the core rod body, it is characterized in that: in the middle of the described core rod body injecting hole is set, injecting hole connects centrosymmetric runner, and flow field end is provided with the injection moulding endoporus.
Described injection moulding endoporus is arranged on the bottom of die cavity.
The present invention is simple in structure, and is reasonable in design, and injecting hole is arranged on the core rod body, will melt plastics by the injection moulding endoporus and inject in the die cavity, and after the sealing ring moulding, the injection moulding salient point of formation is in the inboard of sealing ring, and the smooth outer surface of sealing ring is smooth, and surface quality is good.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of filter sealing ring mould, comprise mobile die body 4, mobile die body 4 mid portions are provided with core rod body 3, injecting hole 2 is set in the middle of the core rod body 3, injecting hole 2 connects centrosymmetric runner 1, and runner 1 end is provided with injection moulding endoporus 5, and injection moulding endoporus 5 is arranged on the bottom of die cavity 6.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
