Abstract
The utility model relates to a novel PTFE pushes mould changes single tapering design that mold design was in the past used, and the mould tapering adopts the ladder tapering, fibrillation process when changing the raw materials and pass through the mould through the ladder tapering for the fibre that raw materials when extrusion produced does not split, has improved properties of product, reduces equipment simultaneously and pushes and shove pressure, and pressure is too big to lead to the fact the damage because of pushing and shove to avoid equipment.
Description
Technical field
The utility model relates to a kind of novel PTFE pushing die.
Background technology
What polytetrafluoroethylene (PTFE) disperse materials goods adopted is paste shape extrusion mode, in this production process, equipment and mold has a specific compression ratio, the raw material itself used also has a compression ratio, just can produce the product of good quality after two compression ratios mate mutually.Because equipment is fixing in real production process, when needs use low compression ratio raw material to produce, the two compression ratio does not mate, and the product surface produced is coarse, and size is uneven.Meanwhile, it is large that pressure pushed by production equipment, is easy to cause device damage.
Now, needing on Design of Dies, make some and change, by changing polytetrafluoroethylene (PTFE) at mould place fibrotic processes, finally changing product surface performance, reduce equipment simultaneously and push pressure.
Summary of the invention
The utility model relates to a kind of novel PTFE pushing die, and object is to change product surface performance, reduces equipment simultaneously and pushes pressure.
The technical solution of the utility model: a kind of novel PTFE pushing die, comprises formwork and inwall, and inwall comprises the first tapered section, the second tapered section and profiled section, and the first tapered section is connected with the second tapered section, and the second tapered section is connected with profiled section.
Optimally, the second tapered section tapering is greater than the first tapered section tapering.
Optimally, the second tapered section tapering is set to 40 °-80 °.
The technical solution of the utility model inwall comprises the first tapered section, the second tapered section and profiled section, first tapered section is connected with the second tapered section, second tapered section is connected with profiled section, the control to compression ratio is realized by two tapered sections, improve the quality of production, reduce production equipment loss, structure is simple, easy to use, practical.
The utility model second tapered section tapering is greater than the first tapered section tapering, and tapering is different, and material is increased through the second tapering pressure, the material little to compression ratio adds can increase material compression ratio man-hour, improve product surface quality, save power, practical.
The utility model second tapered section tapering is set to 40 °-80 °, can according to the needs of different operating compression ratio, second tapered section is set to different tapering, meet the demand of multiple compression ratio, without the need to adjusting the operating pressure of complete machine, simple, and effectively cost-saving, improve the quality of production, practical.
The beneficial effects of the utility model are, change single taper design that Design of Dies in the past uses, the utility model mould tapering adopts step conical, by step conical feed change by fibrotic processes during mould, the fiber produced during material extruding is not ruptured, improve properties of product, reduce equipment simultaneously and push pressure, pressure is excessive causes damage because pushing to avoid equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel PTFE pushing die of the present utility model.
1-first tapered section; 2-second tapered section; 3-profiled section; 4-formwork.
Detailed description of the invention
Embodiment 1:
The technical solution of the utility model is: a kind of novel PTFE pushing die, comprise formwork 4 and inwall, inwall comprises the first tapered section 1, second tapered section 2 and profiled section 3, first tapered section 1 is connected 2 with the second tapered section, second tapered section 2 is connected 3 with profiled section, second tapered section 2 tapering is greater than the first tapered section 1 tapering, and the second tapered section 2 tapering is set to 40 °.
During use, mould is fixedly connected with production equipment, raw material is compressed to pushing die through production equipment, first time supercharging is carried out through the first tapered section 1, then secondary booster is carried out through the second tapered section 2, final arrival profiled section 3, enough large pressure is shaping by material extruding, and smooth surface, without the need to larger equipment dynamic.
Embodiment 2:
The distinguishing characteristics of the present embodiment and embodiment 1 is, second tapering of the present embodiment is set to 60 °.
Embodiment 3:
The distinguishing characteristics of the present embodiment and embodiment 1 is, second tapering of the present embodiment is set to 80 °.
The above, only to preferred embodiment of the present utility model, be not do other forms of restriction to the utility model, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But, everyly do not depart from the utility model plan content, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and remodeling, still belong to protection domain of the present utility model.
