Abstract
The utility model relates to a pipe making mould sleeve. The pipe making mould sleeve comprises a mould sleeve and a mould core, wherein a first circular concave opening is formed in the inner wall of one end of an outlet pipe opening of the mould sleeve; a second circular concave opening is formed in the outer wall of one end of an outlet pipe opening of the mould core; the first circular concave opening and the second circular concave opening are internally provided with gaskets made of polytetrafluoroethylene. The pipe making mould sleeve provided by the utility model has the advantages that the circular concave openings are symmetrically arranged at the same ends of the mould sleeve and the mould core; the concave openings are internally provided with the gaskets made of the polytetrafluoroethylene so that no PVC (Polyvinyl Chloride) materials are remained at outlets of the mould sleeve and the mould core in the production process; the pipe making mould sleeve is a novel technical scheme and is convenient for popularization and application.
Description
Technical field
The utility model relates to tubing field, particularly a kind of tubulation die sleeve.
Background technology
At present in the time producing pvc pipe, the tubulation die sleeve of pvc pipe comprises mould cover and core rod, in the process of tubulation, each root pvc pipe is produced while end, capital has some PVC material to remain in the exit of mould cover and core rod, if cleaning, will cause the surface irregularity of pvc pipe below, thereby affect the quality of product not in time.
Summary of the invention
For above-mentioned shortcoming, the utility model object is to provide a kind of tubulation die sleeve that can not leave in the exit of mould cover and core rod PVC material.
For achieving the above object, the technical solution adopted in the utility model is: a kind of tubulation die sleeve described in the utility model, comprise mould cover and core rod, on the described inwall that overlaps outlet spout one end at mould, be provided with the first circular recess, on the outer wall of one end of core rod outlet spout, be provided with the second circular recess, in described the first circular recess and the second circular recess, be respectively equipped with the packing ring made from polytetrafluoroethylene (PTFE), described two packing rings adopt interference fit with the first circular recess and the second circular recess respectively.(Polytetrafluoroethene, is generally called " non-sticking lining " or " easy clean pot material " to polytetrafluoroethylene (PTFE); It is a kind of artificial synthesized polymer material that has used fluorine to replace all hydrogen atoms in polyethylene.This material has the feature of antiacid alkali resistant, anti-various organic solvents, is dissolved in hardly all solvents.Simultaneously, polytetrafluoroethylene (PTFE) has resistant to elevated temperatures feature, its coefficient of friction is extremely low, so after can making lubrication, also become the desirable coating of easy clean pot and water pipe internal layer, so do not have metal accumulation in tubulation on polytetrafluoroethylene (PTFE), be difficult for causing steel tube surface below to occur rugged situation.
The utility model compared with prior art, the advantage having is, same one end at mould cover and core rod is arranged with circular recess, in recess, be provided with the packing ring that adopts polytetrafluoroethylene (PTFE) to make, so in the time producing, do not have the exit that PVC material remains in mould cover and core rod, this is a kind of new technical scheme, is convenient to promote the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral is:
1, mould cover; 2, core rod; 3, the first circular recess; 4, the second circular recess,
5, packing ring.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation are only used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of tubulation die sleeve, comprise mould cover 1 and core rod 2, on the described inwall that overlaps 1 outlet spout one end at mould, be provided with the first circular recess 3, on the outer wall of one end of core rod 2 outlet spouts, be provided with the second circular recess 4, in described the first circular recess 3 and the second circular recess 4, be respectively equipped with the packing ring 5 made from polytetrafluoroethylene (PTFE).Described two packing rings 5 adopt interference fit with the first circular recess 3 and the second circular recess 4 respectively.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
Claims (2)
1. a tubulation die sleeve, comprise mould cover (1) and core rod (2), it is characterized in that, described the first circular recess (3) that is provided with on the inwall of mould cover (1) outlet spout one end, on the outer wall of one end of core rod (2) outlet spout, be provided with the second circular recess (4), in described the first circular recess (3) and the second circular recess (4), be respectively equipped with the packing ring (5) made from polytetrafluoroethylene (PTFE).
2. a kind of tubulation die sleeve according to claim 1, is characterized in that, described two packing rings (5) adopt interference fit with the first circular recess (3) and the second circular recess (4) respectively.
