Abstract
The utility model discloses a kind of crowded tubular type mold cores of rail cable, including die body and the mold core pipe for being connected to the die body inner cavity, it is characterized in that, it further include pressure plate and removable connector, the front end of the mold core pipe has the expansion mouth that cooperation is radially limited with the limiting section of the die body, and the pressure plate is connect with the die body by the removable connector and the expansion mouth of the mold core pipe is axially confined on the limiting section.The utility model provides a kind of crowded tubular type mold cores of rail cable, improves the service life of mold, is convenient for mold repair.
Description
Technical field
The utility model belongs to cable mold technical field, and in particular to a kind of crowded tubular type mold cores of rail cable.
Background technique
With the fast development of China's urbanization, the type of cable is changed to underground cable from original aerial cable, buried
Cable protects cable with steel-tape armouring layer substantially, and steel band used in track traffic cable armouring is stainless steel band, is squeezed with common
Tubing die squeeze out sheath when, because core is swung in head, steel band be easy to mold core grind partially, cause burn failure rate compared with
It is high.
Utility model content
The purpose of this utility model is that providing a kind of rail cable crowded pipe for the above-mentioned insufficient and defect of the prior art
Formula mold cores, to solve the above problems.
The technical issues of the utility model is solved can be achieved through the following technical solutions:
Rail cable is with tubular type mold cores are squeezed, and including die body and the mold core pipe for being connected to the die body inner cavity, feature exists
In further including pressure plate and removable connector, the front end of the mold core pipe has and the limiting section of the die body radially limits
The expansion mouth of cooperation, the pressure plate are connect with the die body by the removable connector and by the flarings of the mold core pipe
Portion is axially confined on the limiting section.
In a preferred embodiment of the utility model, the removable connector is screw.
In a preferred embodiment of the utility model, the expansion mouth is annular convex platform, and the limiting section is limit
Step.
Due to using technical solution as above, the utility model has the beneficial effects that: improving the use longevity of mold
Life is convenient for mold repair.
Detailed description of the invention
Fig. 1 is the crowded tubular type mold cores structural schematic diagram of rail cable of utility model.
Fig. 2 is the crowded tubular type mold cores main view of rail cable of utility model.
Specific embodiment
Referring to a kind of rail cable shown in Fig. 1 with squeezing tubular type mold cores, including die body 100 and it is connected to die body 100
The mold core pipe 200 of inner cavity, further includes pressure plate 300 and removable connector 400 between die body 100 and mold core pipe 200, detachably
Connector 400 is preferably screw, and the front end of mold core pipe 200 has the flaring with the radial limit cooperation of the limiting section 500 of die body 100
Portion 600, expansion mouth 600 in the present embodiment are annular convex platform, and limiting section 500 is limited step.Pressure plate 300 passes through removable
Connector 400 is unloaded to connect with die body 100 and the expansion mouth of mold core pipe 200 600 is axially confined on limiting section 500.If mold
Inner hole damage, directly changes the mold core pipe 200 by removable connector 400.
Mold die body 100 and 300 material therefor of pressure plate in the present embodiment are common No. 45 steel, to improve the resistance to of mold
Mill property, 200 material of mold core pipe are quenched 45 steel.Because quenched material hardness is higher, if not only turning is fast using regular turning tool turning
Degree is slow, and cutter is easily worn, and special tool to be processed, and in order to improve processing efficiency, is repeatedly linked up with cutter producer
And a kind of on probation, special import blade (trade mark C120404) of final choice, to complete the processing of the mold.
