Description
Technical field
The utility model belongs to extrusion formation equipment technical field more particularly to a kind of strip molding die.
Background technology
Ultra-high molecular weight polyethylene is engineering thermoplastic material, it combines the superior function of most of plastics, impact resistance,
Low temperature resistant, wear-resistant, resistant to chemical etching, self-lubrication, absorb impact energy, this six characteristics be in current plastics possessed by most
High level, for this novel plastic product using extensively, demand is big in recent years.
" performance is remarkable, processing difficulties " is a big feature of ultra-high molecular weight polyethylene, is difficult to adopt conventional polymer
Processing method is molded.For plate, common forming method is compression molding method.It is after pressurizeing to mold charge, by mould
Tool and powder raw material, by water cooling after pressurize, finally take out product by deep fat heating, plasticizing.In this moulding process, close
Key is to control pressure, sintering temperature, time and cooling velocity.Wherein cooling process is after molding in die cavity when product, by
Cooling system cools down to mold, can just make product the final shaping and smoothly demoulding, cooling various process parameters are to high score
Color, flatness of sub- weight polyethylene board etc. have significant impact.The cooling time of mold and cooling position are directly related to production
The Forming Quality of product, therefore the position of cooling water channel and distribution are most important.
Currently, the compression molding die of conventional production high molecular weight polyethylene board material is uniformly distributed two in upper and lower mould
A independent S types cooling water channel.Polyethylene board big for thickness, length and width dimensions are small, required precision is not stringent, the cooling system
System can substantially meet the technological requirement of processing.But for thinner thickness and the larger polyethylene board of length and width dimensions, due to
Water channel away from mold working surface farther out, distribution compared with dredge and also water channel length it is too long, the cooling water quick heating in water channel, strip is cooled
Uneven, it is easy that sheet edge ununiform shrinkage is made to generate warping phenomenon, influences machining accuracy and product quality.
Utility model content
The purpose of this utility model is to provide a kind of strip molding dies, to solve the problems, such as that strip inhomogeneous cooling is even.
In order to achieve the above object, the base case of the utility model is：Strip molding die, including cope plate and lower die
Plate, lower template is interior to be equipped with cavity, is equipped with vacuum chamber in cope plate and lower template, vacuum chamber is circumscribed with suction opening, and vacuum chamber leans on
The side of plesiotype chamber is evenly equipped with several vacuum ports, and vacuum port is connected to cavity, and vacuum port is equipped with gas valve with cavity connectivity part；
It is evenly equipped with several water filling ports at left and right sides of cope plate and lower template, is equipped in cope plate and lower template and is connected to water filling port
Circulating water pipeline, the circulating water pipeline of lower template is identical as the profile of cavity, and the circulating water pipeline of cope plate is transversely and horizontally set.
The operation principle of this base case is：When using this mold, in advance by the note of cope plate and lower template the same side
The mouth of a river is connect with cooling water equipment, and the water filling port of the other side is connected to water circulating apparatus；Suction opening and vaccum-pumping equipment are connected
It connects.Then the blank of strip made of single lead screw ex truding briquetting machine is placed in the cavity of lower template, cope plate is put down, make cope plate
It is closed with lower template.Start vaccum-pumping equipment and cooling water equipment.Since suction opening, vacuum port are connected to vacuum chamber, and it is true
It eats dishes without rice or wine to be connected to cavity, therefore the air in cavity all can be extracted by vaccum-pumping equipment, keep cavity closed as one
Vacuum space.Due to eating dishes without rice or wine to be equipped with gas valve with cavity connectivity part, so blank can not enter vacuum chamber from cavity.By
It is adapted with the profile of cavity in the circulating water channel of cope plate and the circulating water channel of lower template, therefore cooling water is by following
When ring waterpipe, cooling water can cool down the strip blank in cavity.To the strip blank in cavity, vacuum,
Quickly setting is realized under the action of cooling water and template.
The advantageous effect of this base case is：This programme by being arranged vacuum chamber in cope plate and lower template, then
Vacuum port is set in vacuum chamber, realizes the vacuum setting of strip blank；Due to being uniformly distributed for the vacuum port that is connected to cavity,
So vacuumizing more uniformly to have ensured the uniformity of strip.This programme is by being laterally arranged circulating water pipeline, with longitudinal direction
The circulating water pipeline of setting is shorter compared to the length of the circulating water pipeline of this programme so that cooling water can pass through cycle faster
Waterpipe ensure that the temperature of cooling water, to more preferable to the cooling effect of strip, cooling efficiency also higher；And recirculated water
Pipeline is identical as the profile of cavity so that cooling water can be flowed along the appearance profile of strip, and cooling effect is more preferable.
As being further improved for this programme, the water filling port of cope plate side is water inlet, and the water filling port of the other side is
The mouth of a river；With the water filling port of cope plate water outlet homonymy be water inlet in lower template, in lower template with cope plate water inlet homonymy
Water filling port is water outlet.The advantage is that by being passed through cooling water from both sides, the cooling rate of strip can be improved.
As being further improved for this programme, the joint place of cope plate and lower template covers one layer of silicon rubber.Advantage exists
In by the way that silicon rubber is arranged, making cope plate and lower template seal even closer, improve the closure of cavity, and then improve
The shaping speed of strip improves working efficiency.
As being further improved for this programme, the vacuum port of cope plate and the vacuum port of lower template are staggered, cope plate
Circulating water pipeline and the circulating water pipeline of lower template be staggered.The advantage is that being arranged so that cavity vacuumizes more
Uniformly quickly, the cooling effect of strip more preferably, cooling rate higher.
As being further improved for this programme, there are two the vacuum chamber of lower template is set, two vacuum chambers are located at the two of cavity
Side.The advantage is that by the way that vacuum chamber is arranged in the both sides of cavity so that mold vacuumizes more thoroughly, improves the molding of strip
Efficiency.
