Description

4 6291 f A7 B7 V. Description of the invention (·!) [Background of the invention] The present invention relates to the use of a servo motor as the driving source for the injection molding process, especially for the product ejection process and the mold removal process. Electric injection molding machine for ultra-precision molding and injection compression molding method using the same. [Conventional Technology] Injection molding machines that use servomotors as the driving source for their processes are now widely used. However, the maximum limit for this case is only for each of the driving sources such as ① measurement resin injection to the cavity, ② measurement of kneaded resin, ③ opening and closing of the mold, ④ gate cut, etc .: 尙 no ejection of the product An example of a process using a servo motor. For this reason, as shown in FIG. 21, the installation part of the gate cutting bolt mechanism (G) has a large number of mechanical parts: the device that can barely be accommodated in this part used the cylinder (60) as a product in the past Drive source of ejector pin (30). [The first problem] Recently, the higher the frequency of the injection molding machine (B), the longer the ejection time of the ejection mold caused problems. If the time is shortened in this part, of course, the correct response in this part is important. However, the cylinder (60) has a limit on the response speed, and in addition, the response time also forms an imbalance. The shortening from the cylinder (60) to the removal of the product and the improvement of the accuracy have reached the limit. As an example, the production cycle time for each product as the target {read the note on the back ^^ item first, then use this page) This paper scale applies to China National Building Standard (CNS) 8 4 this grid (2 丨 0X297 Mm) -4- 1 629t 7 A7 B7 5. Description of the invention (2) is 3 seconds, then the time allocated from ejection to removal of the product is 0.12 ~ 0. 15 seconds, and the use of the cylinder The situation must take 0.2 seconds, corresponding to the cylinder (60) is very difficult. In addition, since the accuracy of the return response of the cylinder (60) is uneven within the range of 0.01 seconds, the product removal time of the work-in-product removal device (not shown) must be increased to obtain 0. 0 2 ~ 0. 0 5 seconds, when the goal is to increase the frequency, there is a disadvantage that the overall time is shortened and the loss time is increased. [Second problem] In addition, in the aforementioned conventional example, an electric injection molding machine using a servo motor is used. The program data for servo control is to feedback control each servo motor in each process, but this control method is to load the data of the encoder installed in the servo motor into the CPU for calculation, and feedback control its position and speed according to the program. Torque etc. ^ ¾ 、 部 中 呔 ^^ t?

That is, no pressure sensor was installed in any place to directly detect the mold clamping force applied to the mold, so feedback control cannot be performed by directly detecting the mold clamping force * [3rd problem point] Paper size Commonly used national standards (CNS) A4 grid (210X297 mm) -5- 4629 Fly 7 A7 B7 V. Description of the invention (3) Electric injection molding machine using most servo motors, each operating mechanism is used separately Servo motor, there will be too many servo motors, not only the increase of equipment cost, but also the disadvantages of complicated control. [Fourth Problem] In recent years, digital technology has become widespread in various fields such as data processing, video, and music. Of course, as a result, digital substrates such as CD or M D or DVD have been put into practical use. Especially for DVD substrates, ultra-fine unevenness engraved in a mold has been required to be accurately converted into a finished product, which was not possible with conventional hydraulic pressure control injection molding machines. Therefore, an injection molding machine partially using a servo motor as described above has been developed. However, with the advancement of injection molding dies, not only injection molding machines but also other injection molding methods have evolved. Such an injection molding machine controls the accuracy of the substrate according to the following conditions. For example, the formation of optical disk substrates, warpage of molded products, adhesion of foreign objects, micropores, gas sintering, and molding cycle are extremely important factors, but the largest The subjects are ① ultra-fine pitch, ② deep pit conversion, and ③ tortuosity below 50 nm; ease (photoelastic coefficient X main stress difference "= shear stress + thermal stress" can be "Suppression of tortuosity" is caused by the substrate forming, which hinders the conversion of fine unevenness. ①Micro • ②Micro ripples β Resin flows along the fine unevenness, and the phenomenon that the resin flow infiltrates the air before and after the wall of the fine unevenness is formed. "Fine air build-up" The reason for this low-air build-up is the low reduction in conversion. The countermeasure is to charge at high speed. 6- The paper size is appropriate; η China National Standard (CNS) A4 specification (210X297 mm) (诮 先Read the note on the back ^ -item reball page) _ order 4 62 9 ^ 7 a7 _____B7_ V. Description of the invention (4) The resin is extremely inhibited from curing and completed filling. However, in the past injection The .type method is important to prevent the solidification of solid grease. In addition, the time of injection compression is also an important factor. In summary, the following is described below. In the past few years, the practical use of digital substrates and their progress have been quite significant. Molding machines and injection molding technology are required to develop new technologies. At the same time, the frequency of molding speed is actively increased, and the solution is to promote the servo of the full drive device. ① The bottleneck of servo is removing the top of the mold from the mold. Servo-driven bolt mechanism, and direct detection of mold parts such as resin / filling pressure of the mold or mold clamping force. On the mobile mold side, pressure sensing is provided to directly detect resin / filling pressure or mold clamping force of the mold. Device: In addition, the case where the pressure sensor is installed on the side of the moving mold is limited to a special structure, and the others are limited by the inability to install a screw mechanism for ejection *, and also limited by space. ② Of course, servo means With feedback control, in the past examples, because the actual resin filling pressure or mold clamping force could not be detected, it was only attached to the servo motor. The feedback control processing of the encoder's data. ③ In addition, servo control and reducing the servo motor at the same time is also a good requirement of the ministry. I!

[Invention Summary] The following describes the problems to be solved by the present invention in order. Review the sample, and solve the problem in the first one: If the higher frequency is used as the standard, the paper size is deducted from the National Building (CNS) A4 (2ΙΟ × 297) «7] 4 629 W A7 B7 V.

In other words, the problem of the present invention is to develop a new mechanism 'and then link with this new mechanism' to replace the cylinder method in order to increase the frequency, so that products can be taken out without wasting time. It is required to be installed in a complicated gate cutting mechanism installation portion without interfering. The second problem is to use a servo motor as the driving source instead of high frequency. At the same time, it directly measures the resin pressure and the mold clamping force on the mold to perform these feedback control. 6 Especially in the mold mechanism Side | Direct detection of mold clamping force, which was impossible in the past, is made possible. The third problem is to reduce the number of servo motors by using two servo motors as much as possible due to the high cost or complicated control of the servo motors: gate cutting and molding die with one servo motor Ejection process, without reducing performance, promotes device manufacturing cost reduction and simplified control. The fourth problem to be solved: In order to achieve the high frequency of molding at the same time, and to improve the reproducibility of the mold from the fine unevenness of the mold to the mold reproducibility * and the stability of the mold quality, the development of electric injection using servo motors The injection molding method of the molding machine, and appropriately controls the speed of measuring the resin injection to the cavity, the time when the gate is cut off, the compression speed of the mold compression, or the pressure control of the mold compression, and the thickness of the molding mold is constant.

Based on this, the mobile mold (1 a) is continuously moved in the mold closing direction from the start of the injection filling of the resin (3) to the start of mold clamping. Therefore, the filling of the resin (3) and the mobile mold (1 a) Act in concert to increase the relative speed of the moving mold (1a) and the filling resin (3): As a result, the filling resin (3) flows more quickly because it is adjacent to the inner surface of the cavity (2). New internal resin is often exposed on the surface, preventing the formation of a surface layer on the resin surface (3). As a result, the transferability of the fine unevenness to the molded product (2 6) is rapidly improved.

The micro-convex formation area of the compression injection molding method is characterized in that "the micro-convex for conversion is formed on the inner surface side (5) J of the cavity (2) of the movable mold (1 a). As mentioned above, the conversion performance can be improved. = Fill the metering resin (3) while moving the moving mold (la), then As mentioned above, the filling resin (3) acts in concert with the operation of the moving mold (7a) to increase the relative speed with respect to the moving mold (1a), so it often exposes new internal resin when it is next to the surface. The inner surface of the recess (5 a) forming the cavity (2) on the side of the moving mold (1 a) is rapidly flowed. As a result, the formation of the surface layer of the resin surface (3) is hindered. This prevents the formation of fine air that impairs the conversion properties. A slight unevenness is formed on the inner surface of the cavity (2) on the side of the moving mold (1 a), and this method can quickly improve the transferability.

Description of the invention (32) It means that after the resin is filled, the mold ( 1) When the mold is closed, the servo motor (40) rotates to drive the pulley (4 1), and rotates the driven pulley (4 3) through the timing belt (4 2) »This driven pulley (43) Rotary housing (501) • The gate cuts off the drive nut portion (44) and is screwed into the hollow screw shaft (30a), so the hollow screw shaft (30a) is advanced by the rotation of the driven pulley (43), facing the pouring The gate (1c) ejects the gate cutting pin connected to the screw shaft (30a) and the gate is cut. In addition, since the spiral portion (27s) of the center ejection rod (27a) is screwed into the ejection nut portion (49), so if the driven pulley (43) is rotated, the ejection nut portion (49) also rotates And the center ejection rod (2 7 a) also moves with it, but because the spiral portion of the center ejection rod (2 7 a) ¢ 27 s and the hollow spiral axis (30 a) are formed into an anti-helix, so As mentioned above, the hollow spiral shaft (30a) advances *, and the center ejector rod (2a) retreats. After the gate cut is completed in this way, the cavity (2) is completely blocked from the outside. '' If the gate cut is completed as described above, the mold clamping state is maintained in this state or the mold clamping is more forceful.

In this case, the points overlapping with the first embodiment (A1) are omitted to avoid complication. Since the injection mechanism section (a) 'of the fourth embodiment (A4) is the same as the first embodiment (A1), the description is omitted. In addition, the fourth embodiment (A4) is characterized by a compression molding method for extremely fine unevenness on an optical disc formed on the inner surface (5 a) of the cavity (2) of the movable mold (1 b), so the focus is on this point. Description of compression molding method. The mold (1) of the mold mechanism section (b) of the fourth embodiment (A4) is slightly different from the case of the first to third embodiments (A1) to (A3) because it is subjected to compression molding. * However, the mold mechanism The part (b) is basically the same as the description of the first embodiment (A 1), so the description is omitted. In the fourth embodiment (A4), the convex surface (5b) forming a part of the cavity (2) is formed on the partition surface of the fixed mold (1b). The corresponding convex portion (5b) constitutes the cavity (2). A part of the concave portion (5b) is formed on the separation surface of the movable mold (7a): when the mold is closed, the 'convex portion (5b) is embedded in the concave portion (5a) »and then is recessed in the movable mold (1a) The facing surface (5) 'of the fixed mold (lb) of the recessed portion (5b), for example, forms fine unevenness for CD or DVD.

Description of the Invention (34) The mold opening / closing crank link mechanism (T) is the same as the first embodiment (A1.), So the description is omitted. Next, the gate cutting / ejecting mechanism section (C) of the fourth embodiment (A 4) provided in the casing (50) will be described. This gate cutting / ejecting mechanism part (C) is a mechanism for gate cutting and ejection. However, as in the first embodiment (A1), separate mechanisms may be provided separately. As in the third embodiment, Reverse spiral cutting and ejection are also possible. The casing (50) is equipped with a gate cutting / ejecting servo motor (40): a transmission belt (42) is connected to a driving pulley (41) mounted on its rotary drive shaft, and is rotated back and forth through a bearing The driven pulley (43) is freely held on the casing (50). The driven pulley (43) is installed on the action nut (451); here, the action nut (451) is screwed forward and backward and is screwed on the action nut portion of the second half of the gate cutting member (30). (30a). The control device (8) is the same as the first embodiment (A 1), so the description is omitted. 'Second > Figure 5 is explained. This figure is a comparison between the compression molding method (the first method) using the electric injection molding machine (A) of the present invention and the injection molding method of a conventional hydraulic injection molding machine.

Description of the invention (35) ^^ 1 1 ^ 1 ^ "Precautions for reading the back first and then keeping this page secret) The dashed line indicates the past example; the upper dashed line is the set pressure of the hydraulically driven moving mold * The dotted line on the side is the output of a hydraulic pressure sensor (not shown) installed in the hydraulic circuit. In the past, the mold compression was driven by hydraulic pressure, and its compression pressure was detected by the oil pressure sensor of the set oil pressure circuit. The oil pressure control was made consistent with the set pressure. However, in the case of oil pressure control, the oil pressure is used. Oil temperature changes, viscosity, and various other changes. Of course, the resin pressure is detected by oil pressure and oil, or the difference between the dynamic and static friction of the moving mold. Therefore, the actual resin pressure in the mold. The waveform indicated by the static change is not consistent with the set pressure. That is, as shown by the upper dashed line, the mold compression pressure has been set from the beginning of the injection process to the mold opening (R 3): in accordance with this set pressure, the compression pressure of the moving mold is controlled by hydraulic pressure to change it, but this is not actually the case. . That is, the output from the oil pressure sensor installed in the hydraulic circuit for mold driving starts to be injected, and resin is filled in the mold cavity. After a period of time, the resin comes into contact with the moving mold and begins to output. (S) indicates this point. "Thereafter, the output of the oil pressure sensor rises sharply while the resin is being charged, and after reaching the peak value (S 1) * the output wave of the resin pressure fluctuates for reasons described below. In other words, the resin pressure in the cavity changes dynamically and does not match the set pressure. In addition, there is a limit to the injection speed of the hydraulic drive, such as (0-R1) in Figure 5, and the injection is performed at a relatively slow speed. As a result, a thin resin film is generated on the surface of the filling resin (3), which deteriorates the processability. At the point (R 1), the injection process is completed, and the mold compression process (R1 — R2), which is the previous stage of the holding process, is moved. However, at this stage, due to fluctuations, the national paper standard (CNS > A4) applies Grid (210X297mm) -38- d 6291 1 A7 _ B7 V. Description of the invention (36) Therefore, the pressure applied to each part of the resin filling is not necessarily, the internal stress of the molding die increases and the tortuosity increases. {诮Read the notes on the back first and then write this page} In this regard, in the present invention, since the pressure of the resin (3) is directly detected by the pressure sensor (7), it can be followed in real time For the compression pressure control of the moving mold (1 a) in the front stage of the holding process, or for the position control of the moving mold (1 a) in the later stage: if it is the range of the injection process (px_P 1), follow The direct detection of the pressure sensor (7) can control the injection speed. The point (PX) is the vertical line (Η 1) rising from the output start point of the pressure sensor (7) and the injection setting speed curve (0 — Intersection of P 1) Next, the function of the fourth embodiment (A 4) will be described. From the raw resin (3c) to the raw material supply funnel (16) until the resin measurement is completed, it is the same as the first embodiment (A1), so it is omitted. The subsequent injection filling process and pressure maintaining process are described later. However, During this period (measurement process), the rotation speed of the screw (4) is to input the output signal from the pulse wave generating device (1 1 a) to the control device (8), and compare it with the setting ；; Feed control, or both, to control the turning servo motor (1 1) so that it follows the setting 値. This point is common to all the examples (A1) to (A5) and the resin measurement is completed. The process of over-moving to injection filling is described in detail, but the injection speed of the screw (4) when the resin is filled is to input the output signal of the pressure sensor (15) to the control device (8). Feedback control is either feedforward control or both, and the control of paper size and speed is based on China National Building Standard (CNS) A4 (210X297 mm)

Description of the invention (37) Servo motor (1 2) is used to follow the setting 値 ° All embodiments (A1) to (A5) ) The operation (the first method) of the compression molding of the mold (1) for the common β resin / filler mold (1) will be described later. The rotation speed of the injection servo motor (12) is detected by a pulse wave generating device (12a). However, the injection speed is controlled by the method of controlling the resin pressure of the filling resin (3) in the mold cavity (2) for direct control. Therefore, at the point (PX), the filling resin (3) contacts the moving mold. (Lc) and then output the data about the resin pressure from the pressure sensor (7), the injection speed control of the pressure sensor (15) can be switched to the injection speed control of the pressure sensor (7). This point is illustrated in the 19th diagram, in the area of (0-P1), speed control is performed from the injection process, of which (0-px) performs the injection speed control of the pressure sensor (15); (px-P1) performs pressure Injection speed control of sensor (7). Of course * (0-P 1) The entire injection speed control of the pressure sensor (1 5) is also possible. However, the injection of the metering resin (3 a) is performed by the servo motor (1 2) for injection, so high-speed injection that is very close to the setting 値 is possible, and it can be completed before the thin resin film is generated on the surface of the resin (3). Injection, significantly improve the transferability * Then, the gate cut is performed, but the time (P 1) is when the pressure sensor (7) indicates a predetermined time, the gate cut member (3 0) is operated to perform The gate is cut off. Therefore, each time the gate is cut at the same resin pressure, the paper size is deducted from the Chinese National Standards (CNS) A4 specification (210X297 mm) (however, the precautions on the back should be read before filling this book.) Order -40- 4 6291 Ί Α7 __Β7 5. The description of the invention (38) is broken, so in the mold cavity (2), the same amount of resin (3) is stably filled each time. Second, move to the holding pressure process [( PI) — (P3)], but in the pressure control area of the front stage, it can be controlled almost by setting the pressure sensor (7) to directly detect the resin pressure in the cavity (2 0). The compression pressure is applied to the filling resin (3) at the time, and the internal stress can be further reduced. It is moved to the position control for the later stage of the holding process [(P 2) — (P 3)], and the filling resin (3) Almost hardened; the position of the moving mold (1 a) must be properly controlled so that its thickness is constant. As mentioned above, the cavity (2) is filled with a certain amount of resin (3) each time, so if the pressure detector (7 ) Is constant, the thickness is also constant. Therefore, if the pressure is controlled during the position control stage, When the detection 値 of the measuring device (7) becomes the setting, the position of the moving mold (1a) is usually a fixed position, and the thickness of the forming mold (26) is also constant. The operation of the mold (1) is used to explain the above process. As shown in Figure 4 * When the mold is closed, the concave part (5 a) of the moving mold (1 a) is inserted into the convex part (5b) of the fixed mold (lb). However, at this moment, the crank link is not fully extended, and it is on the separating surface. There are several gaps. Therefore, the cavity (2) is also wider than when the mold is closed. Next, the servo motor (12) is actuated and the screw mechanism (10) is operated, and the screw ( 4) Move it to the side of the mold (1). * Mix the molten resin (3a) at the tip of the cylinder (1) and inject it into the cavity (2) (refer to Figure 4. The injection speed is to control the paper. Standards are applicable to China National Standard Vehicle (CNS) A4 (210 × 7mm) (诮 Please read the notes on the back before filling in the book I)., Ιτ -41-4 6291; A? B7 V.

The molten metering resin (3a) is injected and filled in the cavity (2), then it comes into contact with the moving mold (1a) and pushes the mold (la) with pressure. The measuring device (7) detects its filling pressure. At this time, as mentioned above, the mold cavity (2) is set to a certain amount, and only its component melt-kneading resin (3) is filled with more than β (0-P1), It is controlled by the pressure sensor (15); or controlled by the pressure sensor (15) (0-ρ X), and controlled by the pressure sensor (7) (ρχ-P1). In addition, the injection process is performed by an injection servo motor (12) to make it follow the set pressure, so the pressure filling is completed before the thin resin film is generated by the pressure filling resin (3). Next, the gate is cut off, but when the pressure sensor (7) indicates the predetermined pressure (P1) *, the gate is cut off immediately, and the supply of the resin (3a) to the cavity (2) is stopped immediately. . (Refer to Fig. 18 (3).) That is, when the mold (1) is clamped, the servo motor (40) is operated and the driven pulley (4 3) is rotated, and the gate cutting member (30) ) Advance, the gate (2a) of the fixed mold (lb) is closed at the front end. Therefore, the mold cavity (2) is completely blocked from the outside in a state where only the mold (1a) is moved and the component is not filled with resin (3). Next, the mold control servo motor (31) is moved again to advance the male spiral rod (44), and the horizontal elbow (35) is pushed to further extend the mold to open and close the crank link, and move the template (1 8). ) Push the fixed mold (lb) with a predetermined pressure. For this reason, the resin (3) is compressed with a very strong pressure, and the hardened recess (5a) is finely concave-convex (5). The paper is sized according to China National Standard (CNS) A4 (210X297 mm) " -42 -4629 !, A7 B7 5. The slight unevenness of the description of the invention (40) is correctly transferred to the surface of the resin (3) (see figure 18 (4)). During this period, the resin pressure is directly detected and compressed by the sensor (7), so that even the mold compression can be performed with high reproducibility. Then, in this state, the resin pressure is directly detected by the pressure sensor (7) and The moving mold (1a) is held to press the resin into a predetermined volume, and it is hardened and filled with the resin (3). Therefore, the molding die (26) has a highly reproducible and uniform meat thickness every time. After the curing of the resin filled resin (3) is completed, as shown in Fig. 18 (5), the mold is controlled by the servo motor (3 1) in the opposite direction to move it away from the movable mold (la) from the fixed mold (lb) side. At this time, the forming die (26) is kept in the original state embedded in the cavity (2) of the moving die (1a) and moved together with the moving die (la). Finally, move to Figure 18 (b), at the completion of the mold opening, make it actuate the servo motor (40), and eject the gate cutting member (30) from the cavity (2), and then set the mold (26) Recycle after demolding. Next, the second method of the mold compression molding method according to the present invention will be described in detail. Since it is an improvement of the first method described in the fourth embodiment (A4), its operation will be described below with reference to FIG. 20. As shown in Figure 20 (1), the mold (1) is clamped *, then the mobile mold (la) is moved to the fixed mold (lb), and the concave of the mobile mold (la) is inserted into the convex portion of the fixed mold (lb) ( 5b). However, at this moment, the crank connecting rod is not fully extended between the separating surfaces (in other words, between the cavity surfaces), which becomes a gap more than the gate cutting timing of Fig. 20 (3). This paper applies the Chinese National Standard (CNS) A4. Specifications (210X297 male) ~~ -43- < Notes on the back of the note, then fill in the winter notes) Binding 4 62 νΚ: / α7 Β7 V. Description of the invention (41) (t) is still in a wide state < < Indicate the gap between the cavity faces by (T) > > 〇 {Please read the precautions on the back side before filling out this page) In this state, the injection will be filled, but as in Section 2 (2) As shown in the figure, the mobile mold (la) injects the filling resin (3) on the way from (T) to (t) in the direction of clamping. At this moment, the surface layer of the resin (3) is generated at the moment of injection, but the resin (3a) moves toward the mold clamping direction, so the resin flows to the cavity (2) of the mobile mold (1a) at a higher speed. The inner surface forms a surface layer or inhibits growth: Therefore, the generation of fine air buildup is suppressed and the resin (3) is firmly adhered to the inner surface (5) where the fine unevenness is formed. Then, the gate is cut (see section 20). (3)) But its timing (P1) is to eject the gate cutting pin (30) when the pressure sensor (7) indicates a predetermined time, and eject it from the moving mold (1a) while it is moving. After that, the gate cut 1 is separated from the cavity (2) from the gate (2a). At this time, the gap between the cavity surface of the movable mold (1a) and the fixed mold (1b) is (t). In this way, the gate cut is performed every time the same resin pressure is used, so the same amount is stably filled in the cavity ¢ 2) each time (however, the aforementioned width (t) is greater than the width of the molding die (2 6) It is also wide, so the filling amount is larger than the volume of the molding die (2 6)) (3) > The symbol (t) Therefore, the final thickness (S) of the molding die (26) is also thick, so 2) Resin (3) or more which is supplied with the product of the molding die (26). The gate is cut off, as the moving mold (1 a) is used to close the mold. This paper is scaled into the state of China. The standard is CNS A4 (210 × 297 mm) 4i629t ry A7 B7. 5. Description of the invention (42) In this state, the servo motor (40) is driven to rotate the driven pulley (43), and then the gate cutting pin (30) is removed from the moving mold (read the precautions on the back and fill in again) On this page) 1 a), proceed to block the gate of the fixed mold (1 b) with its front end blocked, and completely block it from the outside with resin (3) overfilled. The above process (0 — P 1) is controlled by an injection dynamometer (Load Cell); or it is controlled by an injection dynamometer (1 5) (0 — px) and a pressure sensor (54) Control (PX-P1). In addition, the injection filling process is performed by injecting the servo motor (1 2) to follow the set pressure and the moving mold (1a) is moved, so the filling resin (3) is the same as the moving mold (1a). ) The actions are coordinated to increase the relative speed to the moving mold (1 a), and when it is next to the surface, it often exposes new internal resin and forms the cavity (2) on the side of the moving mold (1 a). The recess (5a) flows rapidly behind the inner surface. As a result, the filling is completed before the thin resin film is generated in the filling resin [3], and this situation prevents the generation of fine air accumulation which impairs the conversion property. Therefore, the cavity (2) recessed part (5 a 0) formed on the side of the moving mold (1 a) has a very good transferability, and is transferred to the molding die (26). Second, from the pressure holding process [(PI ) — (P3)] Move to the take-out process, but the pressure-holding process or take-out process is the same as the first method, so its description is omitted.

Description of the Invention (43) All operations, so you can freely control its time or injection speed, pressurization speed, pressurization pressure, and other; the result * can improve the frequency. Especially for the ejection of the molding die after molding, the removal of the molding die The driving source uses a servo motor. Therefore, the accuracy of the return response of the operation is not uneven, and the time consumption of the product removal device to remove the product is less than 0.1 seconds, which can achieve the final high frequency. In addition, a row of gates cut side by side Breaking screw mechanism and ejection The screw mechanism inserts the screw shaft of the ejection screw mechanism into the screw shaft of the screw mechanism for gate cutting, so that the screw mechanism for gate cutting and the screw mechanism for ejection can be held without interfering with holding the complicated mechanism It is located in one place. In addition, according to the present invention, the pressure sensor directly detects the injection pressure, measures the resin, and the clamping force, and performs control: it can control more accurately. Especially, a pressure feeling is provided between the moving template and the casing. It is difficult to directly detect the clamping force actually applied to the mold in the past, but it has become possible with the present invention. Furthermore, according to the present invention, the entire operation of the injection operation is controlled by the servo motor, so the time can be freely controlled. Or injection speed, pressurization speed, pressurization pressure, etc., the frequency can be increased as a result. However, the pressure sensor directly detects the injection pressure, measures the resin pressure, and the mold clamping force, and performs feedback control | more accurate In particular, it is difficult to install a pressure sensor between the moving template and the housing to directly detect the clamping force applied to the mold. It is easy to explain. In addition, the present invention is formed by installing the filling resin in the detection cavity (read the precautions on the back first and then quoting this page) The paper standards are generally based on national standards (CNS > A4 specifications ( 210X297 mm) -46- * ί · 浐 部 -5- ^ ί-; 4 '· ^ ν ^ .τ.ί / ί; Hezhu Fu Yinzhong 4 6291 7 A7 B7 V. Description of the invention (44) Mold According to its output data, it controls at least one of the injection process or subsequent holding process of filling the resin cavity in the mold cavity, and the pressure sensor that controls the whole or a part of the foregoing process. The pressure sensor directly obtains the data about the filling resin; and each process is controlled in real time and correctly. In addition, the timing of gate cut operation is controlled based on the output from the pressure sensor to control the aforementioned time in real time and accurately. Based on the output data from the pressure sensor, the resin injection from the injection mechanism to the mold force is controlled. The speed * can still perform the aforementioned control in real time and correctly. In the method of the present invention, since the injection of the resin is measured and the filling is started, the mobile mold is continuously moved toward the mold clamping direction, so the operation of the filling resin and the mobile mold are coordinated, especially when it is next to the mobile mold. (1 a) The inner surface of the cavity on the side flows and prevents the surface layer forming the resin surface. Therefore, when fine unevenness is formed on the inner surface of the cavity on the side of the moving mold, the method can rapidly improve the transferability. In addition, the resin filled with an amount of more than the volume of the mold is filled into the cavity and then pressed and shrink-molded. Due to this, the mold is compressed until the volume of the mold is compressed, and the mold becomes a high-density substrate. To improve quality.
