Background technique
Cable insulation material development phase needs to test a variety of electric parameters such as dielectric constant, disruptive field intensity, testing of materials
It requires for tested sample to be pressed into chip shape greatly, compression molding instrument is scientific research institution and enterprise in cable material electrical property
The long instrument of test phase.But current compression molding instrument is mostly based on natural cooling or water-cooling pattern, as crosslinked polyethylene
Equal material cures pelletizing temperature is generally in 200 degrees centigrades, and above-mentioned material cooling means cooling rate is very slow, when needing long
Between wait, and be likely to cause the change of performance parameter.Therefore, there can be a kind of test that can quickly make compression molding instrument
The device of material cooling has important practical application value.
Summary of the invention
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide a kind of insulating materials test compression molding instrument
Quick cooler.
A kind of insulating materials test compression molding instrument quick cooler of the invention, it includes liquid nitrogen bottle, control valve, main liquid
Nitrogen channel, driving motor, drive rod, plate, cooling liquid nitrogen channel；The upper end of the liquid nitrogen bottle is connected with main liquid nitrogen channel, institute
The front end for stating main liquid nitrogen channel is connected with control valve, and the driving motor is two, and described two driving motors are in opposite up and down
It is arranged, is respectively connected with drive rod on described two driving motors, the end of the drive rod is equipped with plate, shape between two plates
At press-space, cooling liquid nitrogen channel, the cooling liquid nitrogen channel and main liquid nitrogen channel are provided on the plate of the upside
The connection of liquid nitrogen inlet.
Compared with prior art, the invention has the benefit that shortening cooling time, easy to use, easy to operate, efficiency
It is high.
Detailed description of the invention
Detailed description will be given by the following detailed implementation and drawings by the present invention for ease of explanation,.
Fig. 1 is the structural diagram of the present invention.
In figure: 1- liquid nitrogen bottle；2- control valve；The main liquid nitrogen channel 3-；4- driving motor；5- drive rod；6- plate；7- is cooling
Liquid nitrogen channel.
Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings specific
Embodiment describes the present invention.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit model of the invention
It encloses.In addition, in the following description, descriptions of well-known structures and technologies are omitted, it is of the invention to avoid unnecessarily obscuring
Concept.
As shown in Figure 1, present embodiment uses following technical scheme: it includes liquid nitrogen bottle 1, control valve 2, main liquid nitrogen
Channel 3, driving motor 4, drive rod 5, plate 6, cooling liquid nitrogen channel 7；The upper end of the liquid nitrogen bottle 1 is connected with main liquid nitrogen channel
3, the front end in the main liquid nitrogen channel 3 is connected with control valve 2, and the driving motor 4 is two, and described two driving motors 4 are in
It being oppositely arranged up and down, drive rod 5 is respectively connected on described two driving motors 4, the end of the drive rod 5 is equipped with plate 6,
Press-space is formed between two plates 6, and cooling liquid nitrogen channel 7, the cooling liquid nitrogen channel are provided on the plate 6 of the upside
7 connect with the liquid nitrogen inlet in main liquid nitrogen channel 3.
The working principle of the present embodiment is as follows: on the basis of Yuanping City's plate vulcameter device structure, in upper flat plate structure
Liquid nitrogen container is designed on surface, i.e., in figure shown in liquid nitrogen channel, and side installs liquid nitrogen inlet additional convenient for liquid nitrogen injection on a passage.When
After material is put between two plate of vulcameter, heats up to plate, carry out compressing tablet process after reaching preset temperature, two plates are passing
Smooth thin slice is formed according to predetermined pressure pressed material under dynamic motor effect.After film-making success, closing temperature control system is beaten
It opens liquid nitrogen valve and cooling is rapidly cooled to plate and Internal Experiment material.
Using the cooling compression molding instrument of liquid nitrogen in cross-linking polyethylene materials thin slice preparation process, the cooling velocity of material
It was down to 2 minutes from original cooling 20 minutes, has reached quick cooling effect.
