Abstract
The utility model relates to an experimental vacuum plastic sheet pressing machine, which has a square framework structure. The square framework consists of a top plate, a base plate and studs fixedly arranged at four corners; two guide columns are vertically and symmetrically arranged on a middle shaft between the top plate and the base plate; a guide sleeve is sleeved on each guide column at the lower end face of the top plate; an upper heating plate fixedly arranged on the lower end face of the top plate is arranged on the guide sleeves; a movable plate is horizontally sleeved on the two guide columns between the guide sleeves and the base plate; a closed square vacuum cover is vertically embedded between the movable plate and the upper heating plate; a jack is fixedly arranged on the middle shaft, which is positioned between the top plate and the base plate, of the base plate; and the plunger end of the jack is coaxially sleeved in a lower heating plate in a sliding manner. The sheet pressing machine performs plastic sheeting in the vacuum space formed by the upper heating plate and the lower heating plate as well as a vacuum cover; before the upper heating plate and the lower heating plate are closed, the upper heating plate, the movable plate and the vacuum cover are closed to form sealed space; and therefore, when the upper heating plate and the lower heating plate are pressed to be closed, the pressure on the vacuum cover is reduced.
Description
Technical field
The utility model belongs to field of plastics processing, relates to the plastics compressing tablet, especially a kind of experiment type vacuum plastics tablet press machine.
Background technology
Experiment plastic tablet press machine is the chief component of compressing tablet system, is made up of upper and lower heating plate two parts, is used for the hot pressing film-making process of plastics.Existing experiment plastic tablet press machine does not have pumped vacuum systems, makes processed macromolecular material directly contact with air, and in the hot pressing, oxidation reaction takes place material easily, and then influences the mechanical performance, hot property etc. of material.And the sheet material that experiment plastic tablet press machine makes is mainly used in material properties test, can directly influence test result like this, for experiment is made troubles.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, provides a kind of through vacuumizing the experiment plastic tablet press machine of avoiding material oxidation.
The purpose of the utility model is achieved in that
A kind of experiment type vacuum plastics tablet press machine; Be a quadro frame structure, this quadro frame is made up of top board, base plate and four jiaos of double-screw bolts that installed, and top board and base plate laterally arrange; It is characterized in that: the axis position vertically is symmetrically installed with two guide pillars between top board and base plate; Equal suit one guide pin bushing on these two guide pillars of top board lower surface, install on this guide pin bushing one with the top board lower surface install on heating plate, horizontal set one portable plate on two guide pillars between guide pin bushing and the base plate; The cubic vacuum (-tight) housing of vertical setting-in one sealing between portable plate and last heating plate; The two ends up and down of this vacuum (-tight) housing setting-in are respectively gone in the made caulking groove of portable plate and last heating plate, on being communicated with between heating plate, vacuum (-tight) housing and the portable plate formed space on be communicated with vacuum connection tube on the heating plate, the base plate axis position between top board and base plate is fixed with a jack; The coaxial slip cap of the plunger end of this jack is contained in the heating plate; Spacing being inlaid on the portable plate in this time heating plate upper end, the outer rim of following heating plate is installed in down on the heating plate through the slipper seal of flange-type sealing ring, the last plane of following heating plate and the last plane parallel of following heating plate.
And, a pair of mutual dislocation and expansion sliding block in the opposite direction radially are installed on the following heating plate of portable plate lower surface, in the inner end of each expansion sliding block one spring is installed all, upper surface is shaped on a chamfering in the expansion sliding block outer end.
And corresponding two the guide pillar position average level engagements of said portable plate are equipped with a jackscrew.
The advantage and the good effect of the utility model are:
1, this tablet press machine adopts the vacuum space of upper and lower heating plate and vacuum (-tight) housing formation to carry out the plastics compressing tablet; Because before the upper and lower heating plate closure; Last heating plate, portable plate and vacuum (-tight) housing are closed; Form seal cavity, continue to pressurize when making upper and lower heating plate closed, the pressure that vacuum (-tight) housing bears reduces.
2, this tablet press machine is because of down heating plate is movable, thus the thickness of plastics compressing tablet can transfer within the specific limits, to satisfy the compressing tablet needs of multiple thickness.

Fig. 2 partly cuts open figure for the A-A of Fig. 1 to the cross section;
Fig. 3 is that the B-B of Fig. 2 is to the cross section cutaway view Amplified image.
The specific embodiment
Being described in detail the embodiment of the utility model below in conjunction with accompanying drawing, need to prove that present embodiment is narrative, is not determinate, can not limit the protection domain of the utility model with this.
A kind of experiment type vacuum plastics tablet press machine is a quadro frame structure, and this quadro frame is made up of top board 2, base plate 10 and four jiaos of double-screw bolts that installed 1, and top board and base plate laterally arrange.
The axis position vertically is symmetrically installed with two guide pillars 4 between top board and base plate; Equal suit one guide pin bushing 14 on these two guide pillars of top board lower surface; Install on this guide pin bushing one with the top board lower surface install on heating plate 6; Should go up on heating plate and can adopt various mode of heatings, for example mode such as electrothermal tube heating; Horizontal set one portable plate 7 on two guide pillars between guide pin bushing and the base plate, corresponding two the guide pillar position average levels engagements of this portable plate are equipped with a jackscrew 8 so that portable plate can location and installation on guide pillar.The cubic vacuum (-tight) housing 3 of vertical setting-in one sealing between portable plate and last heating plate; The two ends up and down of this vacuum (-tight) housing setting-in are respectively gone in the made caulking groove of portable plate and last heating plate; Wherein made caulking groove is darker on last heating plate, so that vacuum is covered with bigger axial displacement.On being communicated with between heating plate, vacuum (-tight) housing and the portable plate formed space on be communicated with vacuum connection tube 5 on the heating plate, this vacuum connection tube connects vacuum generating equipment.
Base plate axis position between top board and base plate is fixed with a jack 9; The coaxial slip cap of the plunger end of this jack is contained in the heating plate 11; This time heating plate is flange-type, its spacing being inlaid on the portable plate in upper end, and the mode of heating of following heating plate is identical with last heating plate; The outer rim of following heating plate is installed in down on the heating plate through 13 slipper seals of flange-type sealing ring, the last plane of following heating plate and the last plane parallel of following heating plate.
A pair of mutual dislocation and expansion sliding block 12 in the opposite direction radially are installed on the following heating plate of portable plate lower surface, in the inner end of each expansion sliding block one spring 15 are installed all, upper surface is shaped on a chamfering in the expansion sliding block outer end; The effect jack of expansion sliding block initially drives on the portable plate and moves; Drive the limit point of heating plate in the cubic vacuum (-tight) housing arrival at portable plate after; Expansion sliding block withdrawal under pressure, make jack continue to promote down heating plate carries out the plastics compressing tablet to top offset in vacuum (-tight) housing.
