Abstract
The utility model provides a compound pillar silicon rubber mold. Relates to a mold for electric power fitting production, in particular to an improvement of a composite pillar silicon rubber mold. The composite pillar silicon rubber mold has good exhaust and rubber discharge effects and few defects in the formed umbrella skirt. The forming die comprises at least one group of forming dies, wherein the at least one group of forming dies are arranged in a die frame, each forming die is provided with an exhaust hole, and a plurality of exhaust holes form exhaust channels. The forming die is provided with an overflow groove, and the overflow groove is arranged on the end surface of the forming die and is communicated with the exhaust hole through a diversion groove. The gas in the cavity is exhausted by the radial surface of the umbrella skirt through the overflow groove, and the redundant glue amount and the gas overflow; in the process of injecting glue into the mould, redundant gas can be discharged through the exhaust channel in time, so that gas retention cannot be formed in the cavity, the surface of the produced umbrella skirt is smooth, repair is not needed, and the product quality is good.
Description
Technical Field
The utility model relates to a mould is used in the electric power fitting production, especially relates to a composite support silicon rubber mold's improvement.
Background
The composite support is mainly applied to a converter station and a transformer substation and is used as an element of high-voltage electrical equipment to play a role in supporting and insulating. The converter station and the transformer substation have great functions as the center of the national power transmission and transformation project, and the function of the composite support is also important for ensuring the normal operation of equipment in the converter station and the transformer substation. The silicone rubber umbrella cover of the composite strut is a carrier of the electrical performance of the composite strut, but the appearance condition of the molded silicone rubber umbrella cover is worried about for many years. In the prior art, the composite pillar silicon rubber umbrella cover is formed, so that the umbrella skirt is prone to defects, and the appearance and the performance of the umbrella skirt are affected to a certain extent even if the umbrella skirt is repaired in the later period. The reasons for these situations are that the air exhaust is not smooth during the molding process, the amount of glue is too much, and the like, so how to find out the air exhaust and glue discharge method during the production process is a technical problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a compound pillar silicon rubber mould which has good exhaust and glue discharging effects and few defects of the formed umbrella skirt.
The utility model discloses a following technical scheme realizes: a composite pillar silicon rubber mold comprises at least one group of forming molds, wherein the at least one group of forming molds are arranged in a mold frame, each forming mold is provided with an exhaust hole, and a plurality of exhaust holes form an exhaust channel.
The exhaust holes are communicated with the radial glue overflowing grooves through exhaust grooves, the forming die comprises an upper die and a lower die, and the exhaust holes are respectively formed in the upper die and the lower die.
The joint of the upper die and the lower die is a parting surface, the upper die and the lower die are provided with glue overflow grooves, one end of each glue overflow groove is communicated with the parting surface, and the other end of each glue overflow groove is communicated with the exhaust hole.
The forming die is provided with an overflow groove, and the overflow groove is arranged on the end surface of the forming die and is communicated with the exhaust hole through a diversion groove.
And the lower die is provided with a glue injection hole, and the glue injection hole is communicated with a cavity formed by the upper die and the lower die through a glue injection groove.
Compared with the prior art, the utility model discloses when multiunit moulded die arranges the framed interior formation mould in, exhaust hole formation exhaust passage at same height can in time pass through exhaust passage with unnecessary gas and discharge at mould injecting glue in-process for can not form gaseous detention in the die cavity, the full skirt surface that consequently produces is smooth, need not to repair, and product quality is good.
The forming die is provided with an overflow groove, and the overflow groove is arranged on the end surface of the forming die and is communicated with the exhaust hole through a diversion groove. The umbrella skirt radial surface is an axial combined area of the mold, influences the length of the silicon rubber of the composite strut, and an overflow groove on the umbrella skirt radial surface is used for exhausting gas in the cavity, and the redundant rubber and the gas overflow; in the process of injecting glue into the mould, redundant gas can be discharged through the exhaust channel in time, so that gas retention cannot be formed in the cavity, the surface of the produced umbrella skirt is smooth, repair is not needed, and the product quality is good.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the end face structure of the forming die of the present invention;
in the figure: 1. a cavity; 2. a rectangular groove; 3. a glue overflow groove; 4. injecting glue holes; 5. stringing holes; 6. an exhaust hole; 7. an overflow trough; 8. a guide mating zone; 9. parting surfaces; 10. and a screw hole.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-2, a composite pillar silicone rubber mold comprises at least one set of forming dies, at least one set of forming dies is arranged in a mold frame, each forming die is provided with an exhaust hole, and a plurality of exhaust holes form an exhaust channel. When a plurality of groups of forming dies are arranged in the die frame to form the die, the exhaust holes at the same height form an exhaust channel, and redundant gas can be discharged through the exhaust channel in time in the glue injection process of the die, so that gas retention cannot be formed in a die cavity, the surface of the produced umbrella skirt is smooth, repair is not needed, and the product quality is good.
The exhaust holes are communicated with the radial glue overflowing grooves through exhaust grooves, the forming die comprises an upper die and a lower die, and the exhaust holes are respectively formed in the upper die and the lower die.
The joint of the upper die and the lower die is a parting surface, the upper die and the lower die are provided with glue overflow grooves, one end of each glue overflow groove is communicated with the parting surface, and the other end of each glue overflow groove is communicated with the exhaust hole. The parting surface is a combination area of the upper die and the lower die, and is provided with a rectangular groove, a glue overflow groove and a glue injection hole which play a role in removing redundant glue on the parting surface.
