不発明は、射出成形機などの型締装置の型開閉動作制御
方法に係シ、詳しくは、直圧式ｍ造の型締装置における
型開閉と型締力の制御方法に関するものである。[Detailed Description of the Invention] The invention relates to a method for controlling mold opening/closing operations of a mold clamping device such as an injection molding machine, and more specifically, a method for controlling mold opening/closing and mold clamping force in a mold clamping device of a direct pressure molding machine. It is related to.
現在の型締装置における最大の関心事は、金型を保護し
ていかに正確で迅速に型全開閉させることができるかと
いうことと、射出状態に応じていかに適切に型締力を発
揮はせることができるがということにある。The biggest concerns with current mold clamping devices are how to fully open and close the mold accurately and quickly while protecting the mold, and how to properly exert mold clamping force depending on the injection conditions. The point is that it can be done.

化を与えるためには油圧回路の切換えが必要であり、切
換えのために非常に複雑となる。With regard to the above-mentioned mold opening/closing, it is desired to increase the mold opening/closing speed to 100% from the viewpoint of shortening the molding cycle. It is desirable that the mold opening/closing speed be slow at the beginning and end of the opening/closing operation and fast in the middle in order to protect the molded product and the mold. !・Glue type structure ■The mold clamping device can change the speed mentioned above by changing the rate of change of mechanical force, and the opening/closing speed is generally high, so it is currently the mainstream. On the other hand, a mold clamping device with a direct pressure structure has a cylinder arranged in the forward and backward direction in the direction of the force for opening and closing the mold, so it is necessary to switch the hydraulic circuit in order to change the speed I. It becomes very complicated.
切換えのために例えば＋７ ミツトスイッチを設けて、
加速領域と減速領域の各ス）ｏ−り長と速度とを段階的
に設定するものは、従来から公知である。For example, a +7 mitsuto switch is provided for switching.
It is conventionally known to set the rolling length and speed in stages in the acceleration region and deceleration region.
これによれば、加速頭載と減速領域とで速度が段階的変
化を示すので、清らかな移動が得られないばかりか、シ
ョックを避けられないものとなる。According to this, since the speed shows stepwise changes in the acceleration and deceleration regions, it is not only impossible to obtain clean movement, but also a shock cannot be avoided.
冒速領域を大きくするほど変化率が大きくなって、清ら
かな移動に寿られなぐなる。変化率を押σえるためにリ
ミットスイッチ数を多ぐすることが考えられるが、かえ
って複雑化を招くこととなる。The larger the speed range, the greater the rate of change, and the more pure movement becomes impossible. It is conceivable to increase the number of limit switches in order to suppress the rate of change σ, but this would lead to more complexity.

右されるという欠点があった。Smooth mobility and high speed are inversely related. Therefore, in practice, smooth movement is important from the viewpoint of mold protection, so the high-speed region is slightly lacking in high-speed performance. In addition, in order to match smooth mobility and high speed, many setting conditions regarding limit switches and speed must be satisfied, which requires a certain level of skill from the operator. The drawback was that it was dependent on the skill of the worker.

て型が開き始めようとすると、これに対抗する型締力が
作用するために、型締装置に無理がかかることとなる。Furthermore, there is a problem as to whether the mold clamping force can be exerted appropriately. In the toggle type WII construction, the mold is clamped by the elongation of the ivy, so pressure is applied to the mold. In particular, when the link is fully extended, when the mold begins to open due to the injection pressure, a clamping force acts against this, which puts strain on the mold clamping device.

でサージ圧が発生するために用いられていなかった。Furthermore, adjusting the mold clamping force is very troublesome because it is related to the link length, and is easily damaged by bar load. On the other hand, for products manufactured using direct pressure, it is necessary to increase the mold clamping force by 1 or more before injection, taking into account the time required to increase the mold clamping force. Although it is possible to use a cylinder with a large capacity, it has not been used because surge pressure is generated during the pressure increase process.

目的とする。Therefore, the present invention combines the advantages of the Todal type mold clamping device with a direct pressure type III type mold clamping device, and in particular, realizes high-speed mold opening/closing and improves operability. The purpose is to make a dramatic improvement possible, and also to be able to arbitrarily control the mold clamping force depending on the injection condition.

力を射出状態に応じて制御するようにしたことにある。The feature of the first aspect of the present invention is to determine the mold closing zero point in a state where the mold is closed under low pressure and no foreign matter is pinched, and to set the mold protection area and mold opening amount based on this mold closing zero point, and to perform mold opening/closing. The speed is set, and the mold opening/closing operation is controlled in a predetermined mold opening/closing pattern so that acceleration and deceleration are the shortest depending on the mold opening/closing speed. The feature of the second aspect of the present invention is that the mold clamping force is controlled from the mold clamping zero point according to the injection state as the entire premise of the control in the first aspect.

る。Hereinafter, the present invention will be explained based on the drawings. In a normal molding cycle, a mold closing process, a mold clamping process, a mold releasing process, and a mold opening process operate in the order of one code A-B...Q-A. The mold closing process is indicated by A -I (, the mold clamping process is indicated by H-, the mold unclamping process is indicated by K -H, and the mold opening process is indicated by -M -A). 4. The above mold closing process A -H, firstly, the mold is closed with the minimum pressure necessary to move the mold, and the mold closing zero point H is determined by moving the mold at the mold closing limit 1 in a state where no foreign matter is trapped and noisy.

いが、異物があるということが判明するだけであり、ど
の程度の異物なのか寸法まで検出できるものではない。The mold closing zero point H is in contact with the mold force Za, and serves as the starting point for mold opening/closing operation control. Therefore, for example, a position detection sensor or the like is provided to accurately determine the mold closing zero point Hffi. Second, a mold protection area F-H of a desired distance (time) is set with the mold closing zero point H as a reference. Depending on the mold shape etc., the mold protection area F-H is
Although it is determined carefully, it can be set accurately if the mold closing zero point H is used as a reference. Thirdly, allowable foreign matter detection GH is set as the mold clamping zero point Hi reference. Here, the detection of foreign matter is to protect the mold by monitoring everything such as foreign matter getting caught in the mold mating surface and remaining molded material. As shown in Japanese Patent Application Laid-open No. 18299/1983, many people simply detect a foreign object when the speed drops below a predetermined set speed. The size of the foreign object cannot be detected.

とから成る。Here, since the mold closing zero point H is accurately determined and any dimension is accurately set using this mold closing zero point H as a reference, any dimension can be detected. Therefore, for example, detection in micron units is also possible. Fourth, similarly to the above, the mold closing zero point H
Move the mold with a mold opening amount of 1 based on , and set the mold opening amount completely accurately. Here, the area other than the mold protection area FH is defined as a high-speed mold closing area A-F, and the same area A-F is an acceleration area A-C, a constant-speed mold closing area CD, and a deceleration area D- F
It consists of

制御可能である。Furthermore, fifthly, the high-speed mold closing area A-F and the mold protection area F-
Set the speed of H. Here, in the high-speed closed region A-F, the acceleration region A-C and the deceleration region D-F have the shortest time, and each region A-C, CD, and D-F has the highest speed without any yaw. The mold opening/closing pattern is predetermined so that it can be moved cleanly. Therefore, the rapid mold closing operation is performed in an optimal pattern according to the mold closing speed setting. Here, by setting the mold protection area F and the mold opening amount from the mold closing zero point H, the high speed mold closing area A -
Since F is set accurately, open-loop feedback control is possible.

しい。By the way, the mold opening/closing pattern control described above cannot be put to practical use unless variable hydraulic control is sufficient. Currently, this is limited by the response speed of the control valve. The use of variable control valves such as servo valves with good response makes the car heavy.

−Ｈは、終了する。As mentioned above, in the mold-closing process, by simply setting the mold-closing zero point H'ffi standard and the mold-closing speed, we were able to close the mold with the optimal mold opening/closing pattern that minimizes acceleration and deceleration. . Therefore, as in the past, each condition such as the setting of each stroke length and each speed in the acceleration region and deceleration region, the setting of the stroke length and speed in the high-speed type closed region, etc., are set respectively and satisfiedz-vhuW! ”″′・s′lTOjjM
El! F t,<N~3.1.4 operational stability can be achieved. Thereafter, the mold moves at a low speed at the mold closing speed set in the mold protection area FH. If the mold is not closed at the mold closing zero point H within the set time in the IfF foreign matter detection width G-H, it is determined that a foreign matter is trapped. In this case, if you set the width by taking all factors such as mold elongation into account, if you open the mold and cannot find the foreign object, you can assume that other factors such as mold elongation or pin protrusion are the cause. It becomes possible. When no foreign matter is detected, the mold moves to the mold closing zero point H within a set time, and is detected by a position detection sensor or the like. As mentioned above, mold closing process A

σれ、エヤーベントの機能を発揮させることができる。Next, in the mold clamping step H-, the mold clamping force is controlled from the mold closing zero point H according to the injection state. This is because the variable flow rate valve, which has good responsiveness, allows instantaneous hydraulic adjustment in response to injection conditions, making it possible to put any mold clamping force control into practical use that corresponds to all injection conditions. For example, as shown in the drawing, a low-pressure mold clamping region H-J and a pressure clamping process J-K are set with the mold closing zero point H as a reference. In this case, when I'if is increased for several seconds as in the conventional case,
Since there is no need to consider 'I, it is possible to set all low-pressure mold clamping areas 1 (-J) without immediately increasing the pressure. In the low-pressure mold clamping area H-J, resin pressure is generated in the mold due to injection. By opening the mold to an extent that prevents formation of paris, gas exhaust is promoted and the function of the air vent can be exerted.

続ぜれる。At the timing when the resin is not completely filled with light, the low pressure mold clamping area H-
The pressure is instantly increased from J to high pressure mold clamping area J-K. In the high-pressure mold clamping region J-, high-pressure mold clamping is performed after the mold is slightly opened, so that the resin is compressed and a good product is molded. Here, the low-links method is known as an injection compression molding method, but it is difficult to mechanically set conditions according to slight differences in mold thickness and mold installation, and it is difficult to uniformly grasp the injection condition. In order to
2. Sushi does not necessarily mean that it will be of good quality. The mold clamping process H- is feedback-controlled in a closed loop, and the mold clamping force is controlled so as to reach the set value, and continues at the end of the holding pressure.

きる。For example, gas can be exhausted by instantaneously releasing the mold clamping force in a pulsed manner, or the mold clamping force can be released at the timing of starting injection to create a negative pressure inside the mold.

and set the speed of the high-speed open area M-A. With the above settings, all conditions are met, so especially in the high-speed open area M-A, the acceleration area M-0 and deceleration area P-A are predetermined in advance to be the shortest according to the setting relationship. A mold opening operation is performed in a mold opening pattern. In the constant speed mold opening region 〇-P, high speed mold opening is performed for a sufficient time. In this case, if the speed setting value is lowered, M-N=-Q
- Perform mold opening operation on A. In addition, in the mold closing process, the mold closing operation of A-B-E-F is performed in the same manner as above.

能とした。As explained above, according to the invention, only the advantages of Tokuru's mold clamping device can be utilized on the assumption that the mold clamping device has a direct pressure type structure. In other words, the mold opening/closing speed is predetermined so that the acceleration and deceleration are the shortest depending on the setting of the mold opening/closing speed, and the mold opening/closing can be performed at a high speed similar to the Toge Ishiji pattern, thereby reducing the molding cycle. It was also possible to shorten the

It does not require any other operations, just setting the deformation region (slow type region) and mold opening amount, and setting the speed embryo of each region.
Furthermore, since the mold is opened and closed in an optimal manner, it also leads to improved operational stability.

Therefore, accurate automation of removing the molded product during mold opening can be achieved.
