Abstract
The utility model discloses a sub - injection mold's of silicon rubber insulation sizing material pouring device, including sprue, middle runner and branch's runner, its sprue one end is provided with into jiao kou, and middle runner setting feeds through on one side of the sprue and with the sprue, and branch's runner sets up and feeds through in middle runner both sides and with middle runner, and middle runner sets up bottom the sub - injection mold of silicon rubber insulation, branch's runner and the sub - injection mold's of silicon rubber insulation mould cavity intercommunication, the utility model relates to a sub - injection mold's of silicon rubber insulation sizing material pouring device can avoid the sizing material to receive the hindrance that silicon rubber insulation submodule core exceeds mould size part, and its compound die can the sub - finished product of a plurality of silicon rubber insulation of shaping, has the efficient advantage of shaping, and the sizing material loss is few in addition, the problem of its runner of the sub - injection mold of present silicon rubber insulation adopt hot runner, can receive the mold core and obstruct is solved.
Description
Technical field
The utility model relates to silicon rubber insulator injection molding technical field, is specifically related to a kind of sizing material apparatus for pouring of silicon rubber insulator injection molding.
Background technology
The sizing material runner of silicon rubber insulator injection molding is used to the sizing material smooth sequential of plasticizing to be injected in silicon rubber insulator injection molding die cavity, fill at sizing material and each position pressure being delivered to fully silicon rubber insulator must be guaranteed in sulfidation, therefore, the position of sizing material runner on silicon rubber insulator injection molding, shape and size will directly have influence on Forming Quality and the shaping efficiency of silicon rubber insulator.Current its sizing material runner of existing silicon rubber insulator injection molding is arranged on the side of silicon rubber insulator injection molding, for hot flow path, and exceed die size due to silicon rubber insulator core rod length, obstruction can be caused to sizing material glue inlet tube line trend, a large amount of waste material can be produced on the one hand in runner, this runner of another side arranges and once can only pass through mould molding silicon rubber insulator finished product, and shaping efficiency is low.
Summary of the invention
For the deficiencies in the prior art, the utility model aims to provide the sizing material apparatus for pouring of the silicon rubber insulator injection molding of the plastic multiple silicon rubber insulator of a matched moulds that a kind of sizing material loss is few, silicon rubber insulator shaping efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sizing material apparatus for pouring of silicon rubber insulator injection molding, comprise sprue, intermediate flow channel and branch flow passage, described sprue one end is provided with glue-feeder, intermediate flow channel is arranged on sprue side and is communicated with sprue, branch flow passage is arranged on intermediate flow channel both sides and is communicated with intermediate flow channel, described intermediate flow channel is arranged on bottom silicon rubber insulator injection molding, and branch flow passage is communicated with the mold cavity of silicon rubber insulator injection molding.
Further, described intermediate flow channel has two at least, and namely sprue side is at least provided with two intermediate flow channel be communicated with sprue, and the mold cavity of the silicon rubber insulator injection molding be communicated with branch flow passage has four at least.
Further, the mold cavity of the described silicon rubber insulator injection molding be communicated with branch flow passage is connected.
The utility model has following beneficial effect:
The sizing material apparatus for pouring of a kind of silicon rubber insulator injection molding of the utility model, its intermediate flow channel is arranged on bottom silicon rubber insulator injection molding, obstruction sizing material can being avoided to be subject to silicon rubber insulator core rod exceed die size part, its matched moulds can shaping multiple silicon rubber insulator finished product, there is the advantage that shaping efficiency is high, and sizing material loss is few; Solving current its runner of silicon rubber insulator injection molding, to be arranged on silicon rubber insulator injection molding side be the problem that the sizing material loss that exists of hot flow path is large and shaping efficiency is low.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model will be further described, understands the technological thought that the utility model is claimed so that clearer.
The sizing material apparatus for pouring of a kind of silicon rubber insulator injection molding of the utility model as shown in Figure 1-2, comprise sprue 1, intermediate flow channel 12 and branch flow passage 13, sprue 1 one end is provided with glue-feeder 11, intermediate flow channel 12 is arranged on sprue 1 side and is communicated with sprue 1, intermediate flow channel 12 has two, namely sprue 1 side is provided with two intermediate flow channel 12 be communicated with sprue 1, branch flow passage 13 is arranged on intermediate flow channel 12 both sides and is communicated with intermediate flow channel 12, intermediate flow channel 12 is arranged on bottom silicon rubber insulator injection molding, branch flow passage 13 is communicated with the mold cavity 14 of silicon rubber insulator injection molding, the mold cavity 14 of the silicon rubber insulator injection molding be communicated with branch flow passage 13 has four, and the mold cavity 14 of the silicon rubber insulator injection molding be communicated with branch flow passage 13 is connected.
Certainly, sprue 1 side also can arrange the plural intermediate flow channel 12 be communicated with sprue 1, and the mold cavity 14 of the corresponding like this silicon rubber insulator injection molding be communicated with branch flow passage 13 can have more than four.
Operation principle of the present utility model is: sizing material flows into sprue 1 from the glue-feeder 11 of sprue 1, two intermediate flow channel 12 again through being arranged on sprue 1 side branch in branch flow passage 13, sizing material in branch flow passage 13 flows in mold cavity 14 again, because intermediate flow channel 12 is arranged on bottom injection molding, the obstruction that silicon rubber insulator core rod exceeds die size part can be avoided, its sizing material runner is cold runner, like this can one-shot forming four silicon rubber insulator finished products.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
