Description
Technical Field
The invention relates to the technical field of molds, in particular to a thin water gap glue opening insert of an safety capacitor shell.
Background
The glue inlet of the safety capacitor shell product needs to be arranged on the top surface due to certain special requirements, and in order to meet the production requirements of high-speed and high-pressure injection, the glue dispensing port area needs to be made of special steel as an insert, because of the special requirements of the safety capacitor shell, the splicing trace which can be accepted by the special requirements is usually not more than 4mm, and thus, the difficulty is caused when products/injection raw materials with larger glue inlet sizes are needed. The glue opening insert in the prior art is produced in a standardized mode by adopting a given cylindrical size, but the design range of a glue opening is small due to size limitation on a capacitor shell product, the strength of the insert is difficult to guarantee, and in addition, the special engineering material physical properties of the capacitor shell are regulated, so that an extremely narrow forming window is often formed.
Disclosure of Invention
In order to solve the defects and problems of the mold insert of the safety shell in the prior art, the thin water gap glue opening insert of the safety capacitor shell is provided.
The technical scheme adopted by the invention for solving the technical problem is as follows: the invention discloses a thin water gap glue opening insert of a safety capacitor shell, which comprises a cavity and a core, wherein the cavity is provided with the glue opening insert, the glue opening insert is in a conical shape, the front end of the glue opening insert is a guide section with the length of 1mm, the rear end of the glue opening insert is a large-size section, a transition section is arranged between the guide section and the large-size section, the transition section is in a conical shape, and a certain gap is reserved between the transition section and the cavity.
The angle of inclination of the transition section is 22.5 degrees.
The gap distance between the transition section and the cavity is 0.05 mm.
The invention has the beneficial effects that: compared with the prior art, the safety capacitor shell thin water gap glue opening insert has the advantages that the insert is designed to be conical, the small size of a front-end cavity is reserved, a section of 1mm of matching is arranged, the machining size is convenient to control, the service life of parts is prolonged, the design size of a flow channel can be guaranteed by transition from a 1mm pilot section to a large size section, the strength is guaranteed, a glue injection system is the key of an injection mold, the scheme enables the processing convenience and the cost control to be well balanced on the premise of guaranteeing the injection productivity and the service life of the mold, the design freedom degree is greatly widened, and the stability of injection molding production of products is improved.
Drawings
The invention further discloses a thin water gap glue opening insert of a safety capacitor shell, which is disclosed by the invention, by combining the attached drawings and the detailed implementation mode.
FIG. 1 is a schematic structural distribution diagram of a thin water gap rubber mouth insert of an safety capacitor shell according to the present invention;
fig. 2 is a partially enlarged schematic view of a portion a in fig. 1.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, the thin water gap glue opening insert of the safety capacitor shell of the invention comprises a cavity 1 and a core 2, wherein the cavity 1 is provided with a glue opening insert 3, the glue opening insert 3 is in a conical shape, the front end of the glue opening insert 3 is a pilot section 31 with the length of 1mm, the rear end of the glue opening insert 3 is a large-size section 32, a transition section 33 is arranged between the pilot section 31 and the large-size section 32, the transition section 33 is in a conical shape, the inclination angle of the transition section 33 is 22.5 degrees, a certain gap is left between the transition section 33 and the cavity 1, and the gap distance is 0.05 mm. The transition from the 1mm pilot segment 31 to the large-size segment 32 ensures the design size of the flow channel.
In summary, compared with the prior art, the safety capacitor shell thin water gap glue opening insert provided by the invention has the advantages that the insert is designed to be conical, the small size of a front-end cavity is reserved, a section of 1mm of matching is arranged, the control of machining size is facilitated, the service life of parts is prolonged, the design size of a flow channel can be ensured by transition from a 1mm pilot section to a large size section, the strength is ensured, a glue injection system is the key of an injection mold, the scheme enables the processing convenience and the cost control to be well balanced on the premise of ensuring the injection productivity and the service life of the mold, the design freedom is greatly expanded, and the stability of injection molding production of products is improved.
The present invention has been described in accordance with embodiments thereof with the understanding that the present invention is not limited thereto but rather it is to be understood that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims, and any such modifications, equivalents and the like as fall within the true spirit and scope of the invention.
