Abstract
The invention discloses a kind of safety cap manufacture crafts comprising: Step 1: buffer liner forms, Step 2: safety cap pre-shaped, Step 3: safe cap forming.The present invention is that cap shell is directly molded in buffer liner, simple process, and cap shell and buffering interliner can be made close.
Description
Technical field
The present invention relates to safety cap fields, particularly relate to a kind of safety cap manufacture craft.
Background technique
Traditional safety cap generally comprises cap shell and the buffer liner that is attached in cap shell, when assembling, by buffer liner plug
Enter in cap shell and is coated with glue between cap shell and buffer liner, buffer liner to be connected with cap shell inner wall by glue,
Since glue is difficult the gap filled up between buffer liner and cap shell inner wall, cause buffer liner not close in conjunction with cap shell, meeting
There are gap, this gap can make wearer lead because of secondary impact when traditional safety cap encounters high speed or impacting with high pressure
Cause more serious injury；And buffer liner is to fill in cap shell firmly, buffer liner may deform and lead to the slow of buffer liner
Rush ability decline.The applicant devises a kind of safety cap (publication number CN108433228A) thus, the safety cap in cap shell and
Filled with foaming body made of being foamed as foamed glue between buffer liner, by foaming body come so that buffer liner and cap shell inner wall
It combines closely.For this safety cap due to increasing foaming body, this increased the material cost of safety cap；And this peace
Full cap is that first foamed glue is cooperated between cap shell and buffer liner, then makes foamed glue foam to form foaming material again, thus
So that foaming material is closely linked with cap shell and buffer liner, it is increasingly complex compared to more traditional safety cap in production；And
And buffer liner is still filled in cap shell firmly, buffer liner still may deform and the buffer capacity of buffer liner is caused to decline.
Summary of the invention
The purpose of the present invention is to provide a kind of safety cap manufacture craft, simple process can simultaneously make in cap shell and buffering
Lining is tightly combined.
In order to achieve the above objectives, solution of the invention is:
A kind of safety cap manufacture craft comprising following steps:
Step 1: buffer liner forms: being put into foamed material in buffer liner mold, then add to buffer liner mold
Heat and pressurization, so that foamed material foams in buffer liner mold and forms buffer liner, then remove buffer liner；
Step 2: safety cap pre-shaped: the polymer fiber material of pre-soaked resin is attached on the outer surface of buffer liner, thus
Obtain the safety cap preform being made of the polymer fiber material of buffer liner and pre-soaked resin；
Step 3: safe cap forming: safety cap preform being put into hot briquetting in safety cap mold, so that the height of pre-soaked resin
Molecular fiber material is formed by curing cap shell in buffer liner, so that cap shell is combined together with buffer liner and is pacified
Full cap finished product；Finally, safety cap finished product is taken out from safety cap mold after safety cap finished product is cooling.
In said step 1, the mode being heated and pressurizeed to buffer liner mold is steam heating pressurization.
In said step 1, the heating temperature heated to buffer liner mold is 80 DEG C~150 DEG C, in buffering
The pressure value that lining mold pressurizes is 0.025Mpa~0.3Mpa.
In the step 3, the safety cap mold includes master mold and male model；Safety cap preform is put into safety cap
The method of hot briquetting in mold are as follows: safety cap preform is put into master mold, then male model is put into safety cap preform
And male model and master mold are molded, finally by after molding male model and master mold heat；When the macromolecule of pre-soaked resin is fine
Dimension material is formed by curing the male model stopped after cap shell to after molding in buffer liner and master mold heats.Wherein to the public affairs after molding
Mould and the heating temperature of master mold heating are 70 ~ 150 DEG C.
In the step 3, the safety cap mold includes master mold and air bag；Safety cap preform is put into safety
The method of hot briquetting in hat cone tool are as follows: safety cap preform is put into master mold, air bag is then put into safety cap pre-shaped
In vivo, finally master mold is heated and pressurizes and air bag is inflated；When the polymer fiber material of pre-soaked resin is in buffering
Lining stops heating master mold pressurization and stops being inflated air bag after being formed by curing cap shell.Wherein by safety cap pre-shaped
Body is put into safety cap mold in the method for hot briquetting, and the heating temperature to master mold heating is 70 ~ 150 DEG C, is pressurizeed to master mold
Pressure be 0.1 ~ 1Mpa.
In the step 3, the safety cap mold includes master mold and vacuum bag；Safety cap preform is put into safety
The method of hot briquetting in hat cone tool are as follows: first safety cap preform is put into master mold；Then again by master mold and safety cap pre-shaped
Body is put into togerther in vacuum bag；Then to bag vacuum, so that master mold and safety cap preform fit closely；Finally to mother
Mould and the heating of safety cap preform；Stop after the polymer fiber material of pre-soaked resin is formed by curing cap shell in buffer liner
Master mold is heated.Wherein it is put by safety cap preform in safety cap mold in the method for hot briquetting, to master mold and safety
The heating temperature of cap preform heating is 70 ~ 150 DEG C, after bag vacuum, vacuum degree in vacuum bag be 1mmHg~
76mmHg。
In the step 3, the safety cap mold includes male model and vacuum bag；Safety cap preform is put into safety
The method of hot briquetting in hat cone tool are as follows: first male model is put into safety cap preform；Then again by male model and safety cap pre-shaped
