Description of the Invention () The present invention relates to an injection machine. In detail, it refers to an injection machine. An electromagnetic clamping method and device. Press, it is familiar with the clamping device technology of injection molding machine, which uses hydraulic cylinder or servo motor as the power component for mold closing or opening, and then uses the toggle mechanism and tie bar (Tie_Bar) as the mold clamping. Mechanism for power amplification and transmission; this conventional clamping unit not only has a complicated structure, high dependence on related geometric accuracy, but also uneven distribution of clamping force, resulting in poor clamping effect and easy to cause fatigue damage to the tie rod. occur. Furthermore, with the miniaturization or precision of products, the production of traditional large-scale injection molding machines 10 can no longer take into account quality, efficiency, and cost, so the development of small-sized injection molding machines is necessary; however, the conventional clamping device described above has the above-mentioned shortcomings. Therefore, it is not conducive to the miniaturization of its own equipment and cannot match the development trend of miniaturized injection machines. Therefore, there was the disclosure of the invention of "INJECTION 15 MOLDING METHOD AND APPARTUS WITH MAGNETIC MOLD CLAMPING" in U.S. Patent No. 5,352,394. The traveling process of the front part of the template still uses the servo motor to drive the half template on the lead screw for displacement operation. When the other half of the template is closed, the electromagnetic force is used as the building force source of the clamping force, that is, the current is output to the electromagnetic coil of the half template to generate magnetic attraction. After that, the current supply is cut off to eliminate the clamping force, and the servo motor is used to drive the lead screw in the opposite direction to open the mold. In other words, the above-mentioned invention still uses the servo motor as a power source to complete the displacement of the template to close and open. Work, and this electromagnetic installation is another power source device that generates clamping force. Although this structure solves the above-mentioned practice, this paper size applies the Chinese National Standard (CNS) A4 specification (X297 mm) (please (Please read the notes on the back before filling out this page)

Description of the invention () The sliding slide “Asia” maintains the static plate (20) and the moving plate (40) by corresponding up and down with the guide mechanism Parallelism to ensure high-precision operation. In addition, the sliding limit position of the moving plate (40) to the closed position of the static plate (20) and the joint position with the stopper (32) respectively; The power source device (50) has a magnetic force generating mechanism (60), which includes a power control mechanism (63) and a coil (62), wherein the coil (62) is respectively built in the static plate (20) and the moving plate. In the slot (22) (43) of the plate (40), the current control mechanism (63) is connected to the coil (62) to adjust the magnitude and direction of the current of the coil (62). Control the magnitude and direction of the magnetic force between the static plate and the moving plate; With the combination of the above components, the operating mode of the present invention is as follows: In the initial state, the moving plate (40) is attached to the guide mechanism (30). ), The edge of the limit piece (32), at this time, the mold clamping operation is performed, that is, the current control mechanism (63) is used to supply the coil (62)-the estimated positive Current value, at this time a predetermined magnitude of magnetic attraction is generated between the moving plate (40) and the 15 static plate (20), forcing the moving plate (40) to move toward the static plate (20).

Therefore, the closing force of the moving plate (40) and the static plate (20) is limited by the input current, the number of coil turns and the moving plate (40) and the The maximum spacing of the static plate (20) is affected by factors, so under these conditions τ, the maximum mold opening distance of the moving plate (office and the static plate ⑽) should not be too large. Based on the above reasons, the invention is particularly suitable for small injection The mold clamping device of the machine can be used for injection molding with a small amount and high precision. Of course, if the medium and large injection molding machine products are used, the required number of coil turns and current strength will be due to the large stroke of opening and closing the mold. Increase, so the moment before the mold is closed, the moving plate (40) will produce a large clamping force to the static plate (20), so in order to solve this problem, we can accurately control the current control mechanism (63) As shown in the fourth figure, when the mold is closed, when the moving plate (40) and the static plate (20) have a maximum distance d, the estimated current value for a short period of time is no longer entered. Input, at this time the moving plate (4〇) no longer receives suction after sliding forward to a certain distance, but due to The inertia operation, the moving plate (40) will continue to slide forward, and will be decelerated by the frictional force of the guide mechanism (30) and the guide post (44), resulting in a cushioning effect, until the moving plate (4) Drive at a deceleration until the static plate (20) fits, and then input an estimated current value to the current control mechanism (63) to cause a lock between the moving plate (40) and the static plate (20). Mould force; please refer to the fifth figure II and line 12, which are two other current control methods. The difference from the above is that a certain or non-constant value is given before the moving plate (40) is displaced. The positive current value is given a certain or non-constant negative current value after the displacement. The previous operation is to drive the moving plate (40) to move and accelerate, and the later operation is to decelerate and buffer; please refer to the sixth The figure shows the second preferred implementation of the present invention. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm).
