Abstract
The utility model provides a flow channel structure of one-mould two-cavity polystyrene products. The flow channel structure of the one-mould two-cavity polystyrene products can slow down flow velocity in the process of injection molding; prevent products from leaving flow marks at a pouring gate position, and guarantee attractive appearance of the products. The flow channel structure of the one-mould two-cavity polystyrene products comprises two cavities, glue inlets and flow channels and is characterized in that two sections of the flow channels on the lower portion of the glue inlets form an S-shaped flow channel, and two tail ends of the S-shaped flow channel are respectively communicated with the cavities on two sides of the S-shaped flow channel.
Description
Technical field
The utility model relates to the technical field of mould structure, is specially a kind of flow passage structure of polystyrene products of a mould two-chamber.
Background technology
The runner of the polystyrene products of an existing mould two-chamber is seen Fig. 1, its from glue-feeder 2 ' inflow line flowing channel 3 ', then flow into die cavity 1 ', runner is linear pattern, during injection moulding, flow velocity is too fast, goods will stay current mark clearly at the cast gate place, affect the outward appearance of goods.
Summary of the invention
For the problems referred to above, the utility model provides a kind of flow passage structure of polystyrene products of a mould two-chamber, and when it makes injection moulding, flow velocity slows down, and goods are difficult for staying current mark at the cast gate place, guarantees the appearance looks elegant of goods.
A kind of flow passage structure of polystyrene products of a mould two-chamber, its technical scheme is such: it comprises two die cavities, glue-feeder, runner, it is characterized in that: two sections runners of described glue-feeder bottom are combined to form S shape runner, and two ends of described S shape runner are communicated with respectively the described die cavity of both sides.
After adopting said structure of the present utility model, S shape runner just has a buffering in injection moulding
Effect slows down the speed into glue, and when it makes injection moulding, flow velocity slows down, and goods are difficult for staying current mark at the cast gate place, guarantees the appearance looks elegant of goods.
Description of drawings
Fig. 1 is the structural representation of runner of the polystyrene products of an existing mould two-chamber
Fig. 2 is structural representation of the present utility model.
The specific embodiment
See Fig. 2, it comprises two die cavities 1, glue-feeder 2, runner, and two sections runners of glue-feeder 2 bottoms are combined to form S shape runner 3, and two ends of S shape runner 3 are communicated with respectively the die cavity 1 of both sides.
Claims (1)
1. the flow passage structure of the polystyrene products of a mould two-chamber, it comprises two die cavities, glue-feeder, runner, it is characterized in that: two sections runners of described glue-feeder bottom are combined to form S shape runner, and two ends of described S shape runner are communicated with respectively the described die cavity of both sides.
