Description
Technical field
The present invention relates to mould pressing process technical field more particularly to a kind of molding die for preparing test bars and impact samples
Preparation method.
Background technique
The performance of material determines the application space of material, and it is very big that the superiority and inferiority of toughness of material is applied to influence, and judges
A kind of superiority and inferiority of toughness of material is usually to pass through simply supported beam or izodtest is tested, and root is needed when being tested
According to the test bars of national standard preparation standard specification.
The impact batten of common thermoplastic resin such as LDPE, HDPE, PP, PVC, PS etc. are usually that pass through injection molding machine direct
Injection molding obtains, but can not pass through injection molding machine if the resin such as UHMWPE of very poor for some mobility or even extreme viscosities
Prepare batten.Material very high for some viscosity is usually to first pass through molding template is made, is then cut using universal sampling machine
Batten out prepares notched impact batten if necessary, then needs to prepare notch with dedicated cutter.The shortcomings of doing so
It is：One side program is cumbersome, troublesome in poeration, and the period for preparing test bars is very long；On the other hand it is prepared using universal sampling machine
Test bars size difference it is larger and relatively rough by the side surface cut；When in addition using cutter manufacture notch,
Very serious to the abrasion of cutter, replacement cutter makes sample preparation increased costs.
Summary of the invention
The object of the present invention is to provide for the material that can not prepare impact batten by injection molding and a kind of prepare impact sample
The molding die of item and impact batten preparation method, solve that sample preparation is cumbersome, size is unstable, rough surface and tool wear etc. are asked
Topic.
The object of the present invention is achieved like this, it is a kind of prepare impact batten molding die, including die holder, profiled sheeting,
Pressing plate, demoulding backing plate, location hole, positioning pin, forming tank, overflow launder, gas vent, divides mould opening, backform raised line and activity at top plate
Inserts, it is characterised in that the profiled sheeting is placed in above die holder, and pressing plate is placed in above profiled sheeting and can be fixed with positioning pin, mould
Seat, profiled sheeting and pressing plate have collectively constituted sample preparation mechanism；Profiled sheeting can be placed on top plate, and top plate is placed on demoulding backing plate, top plate,
Profiled sheeting and demoulding backing plate have collectively constituted demoulding mechanism；It is uniformly distributed multiple forming tanks on profiled sheeting, is arranged around forming tank
There are overflow launder and gas vent, for extra material and gas to be discharged, eliminates product defect, be equipped on die holder and pressing plate and divide mould
Opening, convenient for separating die holder, profiled sheeting and pressing plate after molding；Top plate is equipped with backform raised line, quantity and position with
The quantity of forming tank and position are corresponding on profiled sheeting, and the profiled sheeting after separation is placed on top plate and by top plate
Backform raised line demoulds impact batten molding in the forming tank in profiled sheeting.
Each forming tank on the profiled sheeting is equipped with movable removable insert, and removable insert is by plate and V
Type edge of a knife composition, on the side of forming tank, the V-knife mouth being connected on plate is arranged flat-plate compressed towards forming tank direction.
According to the preparation of the shape of forming tank meet the non-notch impact batten of national standard, single v-notch impact batten or
Double V-shaped notch shock batten.
The quantity of the forming tank is 3 to 8.
The backform raised line shape is strip or cylindric.
The size for being dimensioned slightly smaller than corresponding forming tank of the backform raised line.
The application of a kind of molding die preparing impact batten of the present invention, it is characterised in that applied to can not pass through
Injection moulding process prepares the impact batten preparation of the heavy polymer of the UHMWPE of the extreme viscosities of test bars, or uses
In the impact batten preparation of the heavy polymer for the extreme viscosities for adding fluorine-containing auxiliary agent improvement mobility.
A kind of preparation method of molding die preparation impact batten preparing impact batten of the present invention, feature exist
In steps are as follows：
1）Removable insert is put into the forming tank on profiled sheeting；
2）Compression molding agent is put into after die holder, profiled sheeting and pressing plate are fixed with positioning pin series connection to preheat；
3）By step 2）Compression molding agent preheating after, by dividing mould opening to separate pressing plate with die holder and profiled sheeting, addition
Then appropriate material covers pressing plate, carry out precompressed and exhaust, then carry out hot pressing；
4）Step 3）After hot pressing die is cold-pressed, material is made to be fully cooled sizing；
5）By dividing mould opening to separate pressing plate with die holder and profiled sheeting, by top plate, profiled sheeting and backing plate string is demoulded with positioning pin
Connection is put into vulcanizing press and is demoulded.
The beneficial effects of the present invention are：Material in forming tank by hot pressing, cold pressing, demoulding and etc. can directly make
Batten must be impacted, die surface improves the smoothness and dimensional stability on impact each surface of batten, in addition material by polishing
In forming tank be it is molding under the conditions of viscous state or elastomeric state, to the abrasion very little of notch cutter when preparing batten, improve
Cutting-tool's used life.
