Abstract
A plastic pipe forming mould core is characterized in that the mould core is provided with a hollow tubular structure, the inner cavity of the tubular mould core is a cooling water circular channel, and the cooled water inlet and outlet pipe ports communicate with the inlet and outlet ports of the circular channel. The utility model implements forced cooling to the pipe thus to improve the forming speed, reduce the forming distance to create conditions for the implementation of other special processes. So the utility model makes some special pipe production possible.
Description
The utility model relates to mould.More particularly, be a kind of die core for plastic pipe formation.
Along with continuing to bring out of new material, be that the tubing of Facing material is applied more and more widely with plastics.The moulding of this tubing be unable to do without mould.The plastic pipe formation die tool is made of sheathed external mold and core rod usually.The material that injects behind the first one-step forming, utilizes extraneous medium (air or water) cooling and shaping again in the tubular cavity that is made of external mold and column core rod.Existing problem is:
1, high-temperature material forms bonding easily in core surface, causes the shaping pipe madial wall coarse.
2, this mould at all can't some special tubing of moulding.As extrude one-time formed steel-plastics composite pipe.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of improved die core for plastic pipe formation is provided, to improve the madial wall smooth degree of tubing.And the one-shot forming technique of extruding of steel-plastics composite pipe is achieved.
The purpose of this utility model is achieved through the following technical solutions:
Architectural feature of the present utility model is that described core rod is a hollow tubular structures, and the inner chamber of described tubulose core rod is the cooling water circulation canal, and has the cooling water turnover mouth of pipe to be communicated with the circulation canal import and export respectively.
Compared with the prior art, the utility model is by employing hollow tubular core rod, and the inner chamber of core rod is the cooling water circulation canal.Cool off implementing pressure by the cooling water that therefrom flows through attached to the outer tubing to be formed of core rod.Thereby avoided the bonding of material effectively, improved the smooth degree of shaping pipe madial wall in core surface.Because enforcement is cold by force, shaping speed improves greatly.For the one-shot forming technique of steel-plastics composite pipe has been created condition.
Accompanying drawing is the utility model structural representation.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, in the present embodiment, core rod 1 is a hollow tubular structures, and the inner chamber of tubulose core rod 1 is a cooling water circulation canal 2, and has the cooling water turnover mouth of pipe to be communicated with the circulation canal import and export respectively.
Shown in the figure, in the present embodiment, the turnover mouth of pipe of cooling water all be positioned at core rod 1 to go into mould distolateral, in the cavity of core rod 1, pipe 3 in being provided with, cooling water is introduced from interior pipe 3, draws along the madial wall of hollow core rod 1, carry out heat exchange when drawing, to implement to force cooling attached to the tubing on the core rod lateral wall.
Claims (1)
1, a kind of die core for plastic pipe formation is characterized in that described core rod (1) is hollow tubular structures, and the inner chamber of described tubulose core rod (1) is cooling water circulation canal (2), and has the cooling water turnover mouth of pipe to be communicated with the circulation canal import and export respectively.
