Abstract
The utility model relates to a concealed glue feeding device for a plastic mould, which comprises a main runner, a sub-runner and a glue inlet opening, wherein the inlet end of the main runner is connected with the outlet of a plastic melting device; the outlet end of the main runner is communicated with the inlet of the sub-runner; the glue inlet opening is arranged at the outlet of the sub-runner, and is communicated with the cavity of the plastic mould. The concealed glue feeding device is characterized in that an opening is formed between the glue inlet opening and a mould core; an S-shaped pouring gate insert is movably mounted in the opening. The concealed glue feeding device breaks through the application of a concealed pouring gate in the production of thin-walled plastic products, particularly the design of fulfilling mould design schemes of thin-walled products thinner than 1.5 mm by utilizing a concealed pouring gate. The concealed glue feeding device has the advantages that pouring gate residue can be avoided, so that problems caused by follow-up work and manual operation of pouring gate residue removing are solved to reduce processing steps, and improve the quality and production efficiency of the thin-walled products.
Description
Technical field
The utility model relates to a kind of plastic mould, relates in particular a kind of submarine type glue feeding device of plastic mould.
Background technology
Sub marine gate is applied more extensive in the time that plastic mould designs at present, the general product that adopts sub marine gate design, all some some products that product glue position is thicker and exterior quality requirement is low, the general design of gate location is at the medial surface of product, the maximum bright spot of this method for designing is not need artificial removal's cast gate after moulding, and require high product for the thinner exterior quality in glue position, on gate design, can only adopt the mode of directly entering glue in side, but need to increase later process and manually remove cast gate residue problem, so want that for the following thin-wall product of 1.5mm the scheme urgent need searching that utilizes sub marine gate to complete Design of Dies breaks through.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provide a kind of prevent cast gate residual, reduce manufacturing procedure, promote the submarine type glue feeding device of the plastic mould of thin-wall product quality.
In order to solve above technical problem, the utility model provides a kind of submarine type glue feeding device of plastic mould, comprise sprue, runner and glue-feeder, described sprue arrival end connects the outlet of plastic cement melting appartus, its port of export is communicated with described runner entrance, described glue-feeder is arranged at the exit of described runner, and be communicated with the die cavity of plastic mould, it is characterized in that: between described glue-feeder and mould core, be provided with a perforate, described tapping is movably installed with sprue mold insert, described sprue mold insert is S shape, and width is greater than described glue-feeder width.
The technical scheme that the utility model further limits is:
Further, described perforate is square opening.
Further, described sprue mold insert is column ironware, and described sprue mold insert is embedded in the described square opening at core rod cast gate place, and effect is to control the position of glue-feeder in product side by the height of bottom.
Further, described sprue is that cross section is the pipeline of circle zigzag, and described runner is that cross section is the pipeline of circular arc.This design is more convenient for the flow velocity of liquid plastic cement.
Further, the diameter of described sprue is 3.00mm.
Further, the diameter of described runner is 2.00mm.
Further, described glue-feeder is rectangle goose-headed structure, and long is 1.18mm, and wide is 0.23mm.
Further, described sprue mold insert length is 37.33mm, and width is 3.58mm, and height is 5.55mm.
The beneficial effects of the utility model are: the utility model has been broken through the following thin-wall product of the sub marine gate application in thin-walled plastic production, especially 1.5mmm and utilized sub marine gate to complete the design of the scheme of Design of Dies.The utility model can prevent cast gate residual, without later process with manually remove cast gate residue problem, reduced manufacturing procedure, promoted thin-wall product quality and production efficiency.
Brief description of the drawings
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of structure described in Fig. 1 embodiment;
Fig. 3 is glue inlet structure schematic diagram.
Detailed description of the invention
Embodiment 1
The submarine type glue feeding device of a kind of plastic mould that the present embodiment provides, as shown in Figures 1 to 3: comprise sprue 1, runner 3 and glue-feeder 4, sprue 1 arrival end connects the outlet of plastic cement melting appartus, its port of export is communicated with runner 3 entrances, glue-feeder 4 is arranged at the exit of runner 3, and be communicated with the die cavity of plastic mould, cut a square opening at cast gate and the runner design place line of product, and inlay the irony sprue mold insert 2 of a S shape at square opening place.
Sprue 1 for cross section be circle zigzag pipeline, the arcuate structure that runner 3 is banana-shaped for cross section.This design is more convenient for the flow velocity of liquid plastic cement.The diameter of sprue 1 is 3.00mm.The diameter of runner 3 is 2.00mm.Glue-feeder 4 is rectangle structure, and long is 1.18mm, and wide is 0.23mm.Sprue mold insert 2 length are 37.33mm, and width is 3.58mm, and height is 5.55mm.
Mainstream channel 1 effect is the main thoroughfare that the plastic cement of thawing enters mold cavity; Runner 3 is branches of sprue 1, and effect is the passage that plastic cement separately enters multiple mold cavities; The effect of glue-feeder 4 is positions that plastic cement is filled with the curing rear final sum separation of products of mold cavity.
Mode of operation of the present utility model is: can adjust as required the height of ironware 2, thereby control the height and position of cast gate on product sidewall.Operate very convenient.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
