Description
Technical field
The present invention relates to peep hole production technologies, more specifically more particularly to a kind of hot melt peep hole production technology.
Background technique
Welding, also referred to as welding, Rong connects, and is a kind of jointing metal in a manner of heating, high temperature or high pressure or other heat
The manufacturing process and technology of plastic material such as plastics, modern times welding energy source there are many kinds of, including gas flame, electric arc, swash
Light, electron beam, friction and ultrasonic wave etc..Other than use in the factory, welding can also carry out in a variety of contexts, such as wild
Outside, under water and space.No matter wherein, welding all may bring danger to operator, so must take when being welded
Safeguard procedures appropriate.The injury that welding may cause to human body includes burn, electric shock, inpairment of vision, sucking toxic gas, purple
Outside line overexposure etc. needs to observe welded condition, internal PE colloidal sol by peep hole generally in tubing socket joint erecting and welding
It is observed by peep hole and overflows situation, to prove internal hot melt in place.
But peep hole majority traditional at present is electric drill perforating peep hole, causes to solve the bad control of hot molten time, and
And also by Current Voltage it is unstable caused by welding effect it is bad, it is also necessary to veteran worker operates, practicability compared with
It is low, be not suitable for mass production promotion, for this purpose, it is proposed that a kind of hot melt peep hole production technology.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of hot melt peep hole production proposed
Technique.
To achieve the above object, the invention provides the following technical scheme: a kind of hot melt peep hole production technology, including it is as follows
Step:
S1, a diameter 8mm, depth 5mm peep hole needle placement shrinkage pool are opened on injection forming mold；
S2, peep hole needle length 1.5cm, diameter 8mm cylindrical needle, peep hole needle are mounted on mold peep hole needle and place shrinkage pool
It is interior, protrude length 1cm；
Semi-finished product are placed on injection molding bracket by S3, according to the technological requirements, adjusting process data, replacement adjustment mold；
S4, starting cradle, semi-finished product be inserted in injection molding core touch in, start up and down grinding tool molding button up and down shaping mould
Tool fits like a glove with semi-finished product tubing；
S5, starting injection molding extruder switch, left and right injection molding extruder start simultaneously, and injection moulding head, which enters in molding die, to be opened
Begin to be molded；
Using hot melt peep hole needle protruding parts when S6, injection molding, peep hole is formed in molding die；
Injection molding extruder automatically exits from molding die after the completion of S7, injection molding, and after the completion of to be cooled, upper and lower injection mold is automatic
Die sinking, exits core manually and touches, and starting injection molding bracket exits injection mold and completes injection molding.
Preferably, in S1 position of opening under molding die mold central point apart from the position bellmouth outer edge 3.5cm.
Preferably, 100% is carried out to hot melt peep hole and checks that separate the sheep from the goats superiority and inferiority.
Preferably, in S5 injection temperature at 245 DEG C ± 5 DEG C.
Technical effect and advantage of the invention:
The present invention observes welded condition in tubing socket joint erecting and welding, through peep hole, and internal PE colloidal sol passes through observation
Situation is overflowed in hole observation, to prove internal hot melt in place.Hot melt peep hole gets rid of traditional electric drill perforating observation technique, solves
The certainly bad control of hot molten time, not by Current Voltage it is unstable caused by welding effect it is bad, with artificial experience hold defect.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Every other embodiment obtained is put, shall fall within the protection scope of the present invention.
Embodiment
A kind of hot melt peep hole production technology, includes the following steps:
S1, a diameter 8mm, depth 5mm peep hole needle placement shrinkage pool are opened on injection forming mold；
S2, peep hole needle length 1.5cm, diameter 8mm cylindrical needle, peep hole needle are mounted on mold peep hole needle and place shrinkage pool
It is interior, protrude length 1cm；
Semi-finished product are placed on injection molding bracket by S3, according to the technological requirements, adjusting process data, replacement adjustment mold；
S4, starting cradle, semi-finished product be inserted in injection molding core touch in, start up and down grinding tool molding button up and down shaping mould
Tool fits like a glove with semi-finished product tubing；
S5, starting injection molding extruder switch, left and right injection molding extruder start simultaneously, and injection moulding head, which enters in molding die, to be opened
Begin to be molded；
Using hot melt peep hole needle protruding parts when S6, injection molding, peep hole is formed in molding die；
Injection molding extruder automatically exits from molding die after the completion of S7, injection molding, and after the completion of to be cooled, upper and lower injection mold is automatic
