专利摘要:
Method and apparatus for injection compression molding' of thermoplastic parts. A preferred apparatus (100) includes a platen assembly 106, a toggle clamp assembly 102, a screw injection assembly 101, a hydraulic system suitable for providing power to the toggle clamp assembly 102 and the screw injection assembly 101, and a control system 88 for operatively controlling the various hydraulic devices associated with the molding apparatus. The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle clamp assembly 102. Preferably, the toggle clamp assembly 102 provides multiple-stage compression of the resin to first redistribute the resin and vent the, cavities and, second, compress the resin to compensate for cooling-induced shrinkage thereof. In the multiple cavity em-' bodiment, because all cavities 7 are equally compressed simultaneously, control of the molding process and balancing of the mold are readily accomplished. The method and apparatus are particularly well suited for molding optical lenses and disks. Printed circuit substrates can also be molded thereby.

专利说明:

This invention relates to a process for the manufacture of polymer products, such as optical lenses and storage disks, by injection molding.
The purpose of the invention is to improve the quality of products due to more accurate stripping of the imprint from the surface of the mold by casting and reducing stresses and double refraction.
Figures 1-7 show the position of the main elements of the form at various stages of the process.
The method is carried out as follows.
After the end of the previous cycle, the first 1 and second 2 injection molding plates of the dividing line with the corresponding decoration molding inserts 3, 4, installed with the possibility of interaction with the general corresponding supports 5, 6. are in the position of fig. 1. Molding insert 3 is installed with the ability to move within the mechanical stops (not shown).
By the beginning of the next cycle (Fig. 2), by means of the spring 7, the first plate is moved away from the stops 8, so that a working compression stroke is created (usually not more than 0.875
 H
about
00

with
1.5 mm). The stem of the holding mechanism 9 exits the cylinder.
Injection moldings 3, associated with the uprights 10, are held in the same position by mechanical stops. As a result, there was an increase in the volume of the injection cavity, while with respect to the separation line the injection moldings were diluted to pre-increase the volume of the cavity, exceeding the maximum volume occupied by the polymer at atmospheric pressure.
Thus, the volume of the casting cavities is determined by a combination of the distance between the second casting plate 2 and the first 1, the stationary plate 11 and the installed mechanical restraints of the casting inserts 3.
Next, the movable plate 12 is brought closer to the stationary plate 11 (FIG. 3), which leads to the complete closure of the dividing line and sealing of the casting cavities formed by inserts 3, 4. The sealing along the dividing line between the plates 1, 2 is provided by springs 7 or hydraulic cylinders in the preferred case option. The slight compression of the springs 7 is accompanied by a decrease in the initial clearance before filling.
At the next stage, the melt is injected into the increased casting cavities (Fig. 4), with the polymer volume at least corresponding to the mass of the finished product. When the volume of the melt exceeds the volume of the cavity, the melt is compressed to a predetermined level of pressure in the cavity. This latter phase, with increasing pressures, creates undesirable stresses during the casting in the molded optical part. Before completing the introduction of the polymer, the cavity volume is reduced due to the closing force of the injection molding machine.
Next, the movable plate 12 (Fig. 5) is moved to the stationary 11 to compress the melt by means of injection moldings 3, 4. The compression force is maintained until the polymer is extruded from the injection cavity to the final volume of the product corresponding to the cavity volume defined by the mechanical limiters of injection molding 3, four.
Preferably, the position and speed of movement of the movable plate 12 is controlled so that a two-stage compression of the melt is created by the main closing force at a higher speed in the first stage, at which the introduced polymer volume is redistributed inside the reduced volume of the molding cavity, and at a lower speed in the second stage, wherein the volume of the cavity to be filled is further reduced to increase the compression of the polymer.
During the second stage, the polymer is cooled and hardens with continued compression pressure so that the molding is improved and the heat is corrected.
0 shrinkage.
By lowering the temperature of the polymer to the glass transition temperature, the form can be opened (Fig. 6), and the product is removed from it (Fig. 7).
5 The first stage of squeezing lasts 1/201 / 15 of the duration of the second stage and the next one, which lasts for the remainder of the cycle with the closed form until the time
0 open mold and product removal.
The method can also be carried out with floating injection moldings 3 with respect to the first plate 1 so that the volume of the molding cavity is increased by melt injection into it. In this case, the first plate 1 protrudes by a predetermined amount, as before, but the support plate 13 is not associated with it. In the original version, the injection moldings 3 remain in a relatively forward position due to the minimal frictional forces between the insert and the plate 1. In an embodiment of the method, when the melt enters the cavity after injection, the melt pressure is fast
5 rises until it exceeds these friction forces, and the melt retracts inserts 3 backward, until there is still enough melt in the enlarged cavities to exert a pressure
0 specified friction braking when sliding. The rest of the cycle is identical to that described.
