Description

Mold angle decision system for Injection molding simulation

The present invention relates to a mold angle determination system for simulating injection molding for reducing the amount of bubbles generated in an injection resin filled in a cavity of the mold.

In order to manufacture an injection product, injection resin is filled in the cavity of the mold.

The injection resin filled in the cavity of the mold may be classified into a low-viscosity resin having a low-viscosity characteristic and a high-viscosity resin having a high-viscosity characteristic according to the viscosity. For example, the high-viscosity resin may be a plastic resin and a silicone resin, and the low-viscosity resin may be a urethane resin and an epoxy resin including molded urethane.

However, when the low-viscosity resin is filled in the cavity of the mold, the flow of the low-viscosity resin is affected by gravity. Therefore, bubbles are generated in the low-viscosity resin due to the influence of gravity. These bubbles cause defective bubbles and cracks that occur in the injection product.

Therefore, in order to reduce the amount of bubbles generated in the injection resin filled in the cavity of the mold, Patent Publication No. 2017-0116504 discloses a counter pressure method in which the injection resin filled in the cavity of the mold is pressurized with a pressurizing medium, An injection molding apparatus capable of reducing bubbles generated in an injection resin has been disclosed.

However, in the prior art, in order to pressurize the injection resin filled in the cavity of the mold with the pressurizing medium, a sprue in the form of extending from the outside of the mold to the cavity, and an air supply device for supplying the pressurized medium through the sprue, etc. Due to this necessity, there was a problem in that it was difficult to reduce the weight of the mold.

Overall, the mold 100a has a structure rotatable through the base 200a and the rotating part, and the angle of the mold 100a can be adjusted by the manipulation unit 400 or the motor, and the control unit 800 is the mold 100a. ), an optimal value of the angle value of the mold 100a is determined by simulating the amount of bubbles generated in the injection resin according to the change in the angle value of the mold 100a due to the rotation of the mold 100a.

For example, the control unit 800 may determine, among the angular values of the mold 100a, the minimum amount of bubbles generated in the injection resin as the optimal value of the angular value of the mold 100a, and the optimal value of the angular value of the mold 100a. By applying the simulation to the mold, the amount of bubbles generated in the injection resin filled in the cavity of the mold can be reduced.

The mold 100a has a cavity in which the injection resin is filled. The mold 100a may include a fixed mold 100a' and a movable mold 100a''.

The fixed mold 100a ′ may be fixed through screw fastening, and as shown in FIG. 2 , the movable mold 100a ′ may be installed to move forward and backward with respect to the fixed mold 100a ′. Here, advance and retreat of the movable mold 100a`` may be performed by pressing a press, which will be described later.

Each of the fixed mold 100a ′ and the movable mold 100a ″ may include a template 110 , a support plate 120 , a rotating plate 130a , and a hot plate 140a .

The template 110, the support plate 120, the rotary plate 130a, and the hot plate 140a of the fixed mold 100a` may be sequentially arranged along the direction away from the movable mold 100a``, and the movable mold ( The template 110, the support plate 120, the rotary plate 130a, and the hot plate 140a of 100a'' may be sequentially arranged in a direction away from the fixed mold 100a'. 2 to 3, the fixed mold 100a' is shown on the left and the movable mold 100a'' is shown on the right, but the fixed mold 100a' and the movable mold 100a'' can be arranged opposite to each other. have.

The template 110 of the fixed mold 100a ' and the template 110 of the moving mold 100a '' are disposed to face each other, and when the moving mold 100a '' moves forward, the fixed mold of the fixed mold (100a ') The template 110 and the template 110 of the movable mold 100a`` may be in close contact with each other.

A cavity in which the injection resin is filled may be formed in at least one of the template 110 of the fixed mold 100a ′ and the template 110 of the movable mold 100a ″. That is, the cavity may be formed in both the template 110 of the fixed mold 100a ′ and the template 110 of the movable mold 100a ″. In addition, the cavity may be formed only on the template 110 of the fixed mold 100a' or only on the template 110 of the movable mold 100a''.

Hereinafter, for convenience of explanation, modifiers such as the fixed mold 100a ′ and the movable mold 100a ″ will be omitted.

In this embodiment, the template 110, the support plate 120, the rotary plate 130a, and the hot plate 140a are integrally coupled via screw fastening.

The cavity may be filled with an injection resin. In this embodiment, the injection resin filled in the cavity may be a low-viscosity resin. For example, the low-viscosity resin may be a cast urethane resin or an epoxy resin.

The injection resin may be filled into the cavity through a runner penetrating the template 110, the support plate 120, the rotating plate 130a, and the hot plate 140a, and may be filled into the cavity through a runner penetrating only the template 110. have.

A template 110 is detachably coupled to one surface of the support plate 120 . For example, one surface of the support plate 120 and the template 110 may be coupled to each other separably through a screw coupling.

A rotating plate 130a is detachably coupled to the other surface of the support plate 120 . For example, the other surface of the support plate 120 and the rotating plate 130a may be coupled to each other separably through a screw coupling.

The hot plate 140a may be detachably coupled to the rotating plate 130a, and serves to transfer heat to the cavity.

For example, when the injection resin filled in the cavity is a thermoplastic injection resin, a heater (not shown) and a cooler (not shown) may be installed on the hot plate 140a, and at least one of the hot air of the heater and the cold air of the cooler It may be transmitted to the cavity through the rotating plate 130a, the support plate 120, and the template 110.

In addition, when the injection resin filled in the cavity is a thermosetting injection resin, a heater (not shown) may be installed on the hot plate 140a, and the heat of the heater is generated by the rotation plate 130a, the support plate 120, and the template 110. can be transmitted to the cavity through

The mold 100a may be rotated through the bearing 310 of the rotating part coupled to the fixed shaft 210 of the base 200a, and is opposed to the base 200a in the mold 100a, that is, the hot plate 140a. A depression 141 into which the fixed shaft 210 and the bearing 310 are inserted may be formed on the opposite surface.

The base 200a is slidable and may be installed to prevent rotation. For example, the base 200a is slidable along a plurality of guide pins (not shown) penetrating the upper and lower portions of the base 200a. As it is installed, the base 200a may be slidable and may be installed to prevent rotation. Here, the guide pin may penetrate in the same direction as the moving mold 100a with respect to the base 200a, and the end of the guide pin may be fixed to the structure of the injection molding apparatus.

The base 200a is disposed to be spaced apart from at least one side of the mold 100a, and a fixed shaft 210 protruding toward the mold 100a is formed on the base 200a. The fixed shaft 210 may be formed in a cylindrical shape, and is inserted into a depression 141 to be described later.

The mold 100a has a recessed portion 141 formed on a surface opposite to the base 200a, and the fixed shaft 210 is inserted into the recessed portion 141. For example, the depression 141 may be formed by a hole in the center of the hot plate 140a.

The rotating part serves to couple the mold 100a to be rotatably relative to the base 200a, and in this embodiment, between the outer peripheral surface of the fixed shaft 210 and the inner peripheral surface of the recessed part 141 of the mold 100a. The bearing 310 may be provided, for example, the bearing 310 may be a thrust bearing, but is not particularly limited.

The present embodiment may further include a press.

A press (not shown) serves to press the base 200a toward the mold 100a. For example, when a pair of bases 200a are provided on both sides of the mold 100a, the press can press only one base 200a of the pair of bases 200a toward the mold 100a, Both of the pair of bases 200a may be pressed toward the mold 100a.

However, when the base 200a is pressed toward the mold 100a by the press, the bearing 310 may be damaged by the pressing of the press.

In order to prevent this, the width of the depression 141 based on the pressing direction of the press may be smaller than the width of the fixed shaft 210 and the width of the bearing 310 may be configured to be smaller than the width of the depression 141 . Therefore, when the base 200a is pressed toward the mold 100a by the press, the fixed shaft 210 of the base 200a is in close contact with the depression 141 of the mold 100a while the base 200a moves. Distance is limited. As a result, due to the gap formed between the base 200a and the bearing 310 , the contact between the base 200a and the bearing 310 is prevented, and thus the bearing 310 can be prevented from being damaged.

The manipulation unit 400 may be provided in the mold 100a and transmit an external force for rotation of the mold 100a to adjust the angle value of the mold 100a.

As an example, the manipulation unit 400 may be a handle 410 provided to enable manual rotation of the mold 100a.

As another example, the manipulation unit 400 may be a motor (not shown). The motor may rotate the mold 100a under the control of the controller 800 . For example, the motor may rotate the mold 100a by rotating the bearing 310 under the control of the controller 800 or rotating the mold 100a itself.

The angle display unit 500 displays an angle value of the mold 100a. For example, the angle display unit 500 may include an angle plate on which a scale is displayed for each predetermined angle, and an angle needle for displaying a specific scale of the angle plate according to the angle value of the mold 100a. Furthermore, the angle display unit 500 may display the angle value of the mold 100a measured through the angle sensor through the angle plate and the angle needle. Here, as the angle sensor, at least one of a balance sensor, an acceleration sensor, a gyro sensor, a magnetic field sensor, and a tilt sensor may be used.

The angle display unit 500 may be provided on the manipulation unit 400 . This is to prevent the angle display unit 500 from being affected by the temperature change of the mold 100a.

The bubble detection unit serves to detect the amount of bubbles generated in the injection resin.

For example, the bubble detecting unit may use a vision camera 610 built into the cavity of the mold 100a, and a light-transmitting window 620 may be installed between the vision camera 610 and the cavity. Here, the light-transmitting window 620 may be made of a transparent metal material or a neoceram material that is ultra-heat-resistant crystallized glass, but is not particularly limited.

Here, the vision camera 610 may detect the amount of bubbles generated in the injection resin by analyzing image data obtained by photographing the injection resin filled in the cavity of the mold 100a.

As another example, the bubble detecting unit may be an ultrasonic sensor having an ultrasonic oscillation unit and an ultrasonic receiving unit respectively disposed on both sides of the mold 100a with the cavity of the mold 100a interposed therebetween. In this case, the mold 100a is an ultrasonic medium. It may be made of phosphorus stainless steel, and after the ultrasonic sensor is oscillated by the ultrasonic oscillation unit, it passes through the injection resin filled in the cavity of the mold 100a, and then measures the amount of bubbles generated in the injection resin according to the intensity of the ultrasonic wave received by the ultrasonic receiver. can detect

As described above, the control unit 800 recognizes the angle value information of the mold 100a through the angle display unit 500 and the bubble generation amount information in the injection resin filled in the cavity of the mold 100a through the bubble detection unit. Also, among the angle values of the mold 100a , a value that minimizes the amount of bubbles generated in the injection resin may be determined as the optimal value of the angle of the mold 100a. The control unit 800 may be a microcomputer, but is not particularly limited.

Also, the control unit 800 may map and manage the quality quantitative information of the injection product injected from the mold according to the angle value of the mold. For example, the control unit 800 may map the quality quantitative information of the injection product according to the angle value 1 of the mold, map the quality quantitative information of the injection product according to the angle value 2 of the mold, and manage it.

Hereinafter, the operation of this embodiment will be described.

First, the press presses the base 200a toward the mold 100a. This is to prevent separation of the injection resin filled in the cavity of the mold 100a. Referring to the drawings, the arrangement state of the mold 100a is changed from FIG. 2 to FIG. 3 by pressurization.

Next, the cavity of the mold 100a is filled with the injection resin. At this time, the injection resin may be filled in the cavity of the mold 100a by an injection machine (not shown).

Next, the angular value of the mold 100a is changed by periodically rotating the mold 100a by a specific angle. At this time, the control unit 800 recognizes the amount of bubbles generated in each injection resin according to the angle value of each mold 100a.

For example, when the mold 100a is rotated by a specific angle to change the angular value of the mold 100a to a first angular value, the control unit 800 controls the mold 100a according to the first angular value of the bubble in the injection resin. Recognize the amount After that, when the mold 100a is rotated by a specific angle to change the first angle value of the mold to the second angle value, the control unit 800 determines the amount of bubbles generated in the injection resin according to the second angle value of the mold 100a. Recognize. By repeating this pattern, the control unit 800 may recognize the amount of bubbles generated in each injection resin according to the n-th angle value of each mold 100a. However, n is an integer.

Furthermore, the rotation of the mold 100a by a specific angle may include both a forward rotation of the mold 100a by a specific angle and a reverse rotation of the mold 100a by a specific angle.

In addition, the rotation of the mold 100a by a specific angle may be performed by the operation unit 400, and the control unit 800 recognizes the angle value information of the mold 100a through the angle display unit 500, and the bubble detection unit Through this, information on the amount of bubbles generated in the injection resin filled in the cavity of the mold 100a can be recognized.

Next, the control unit 800 determines, among the angle values of the mold 100a , a value that minimizes the amount of bubbles generated in the injection resin as the optimal value of the angle of the mold 100a. Referring to the first angle value of the mold and the second angle value of the mold in the above-described example, the value that minimizes the amount of bubbles generated in the injection resin among the first angle value of the mold and the second angle value of the mold is the mold 100a. It is determined by the optimal value of the angle of .

By applying the optimal value of the angle value of the mold to the simulated mold, it is possible to conveniently reduce the amount of bubbles generated in the injection resin filled in the cavity of the mold.

Hereinafter, a system for determining an angle of a mold for simulation of injection molding according to a second embodiment of the present invention will be described.

4 is a cross-sectional view illustrating a system for determining an angle of a mold for simulation of injection molding according to a second embodiment of the present invention.

In this embodiment, the mold 100b has a template 110 , a support plate 120 , a rotating plate 130b and a hot plate 140b . Here, the template 110, the support plate 120, and the rotating plate 130b of the mold 100b are integrally coupled through screw fastening, and the hot plate 140b of the mold 100b is integrally coupled with the base 200b. do.

Since the template 110 and the support plate 120 are the same as the template 110 and the support plate 120 of the first embodiment, a detailed description will be omitted.

The rotating plate 130b is formed with an insertion shaft 131 protruding toward the base 200a. The insertion shaft 131 may be formed in a cylindrical shape, and is inserted into an annular hot plate 140b, which will be described later.

The hot plate 140b is formed in an annular shape, and is coupled to a surface opposite to the rotating plate 130b in the base 200b. The hot plate 140b has a larger diameter than the insertion shaft 131 , and the insertion shaft 131 is inserted into the hot plate 140b.

The rotating part may include a bearing 310 provided between an outer circumferential surface of the insertion shaft 131 and an inner circumferential surface of the hot plate 140b. For example, the bearing 310 may be a thrust bearing, but is not particularly limited.

That is, in the present embodiment, the mold 100b and the base 200b are integrally rotated via the bearing 310 provided between the hot plate 140b and the base 200b.

A press (not shown) serves to press the base 200b toward the mold 100b. For example, when a pair of bases 200b are provided on both sides of the mold 100b, the press can press only one base 200b of the pair of bases 200b toward the mold 100b, Both of the pair of bases 200b may be pressed toward the mold 100b.

However, when the base 200b is pressed toward the mold 100b by the press, the bearing 310 may be damaged by the pressing of the press.

To prevent this, the width of the insertion shaft 131 may be smaller than the width of the hot plate 140b and the width of the bearing 310 may be smaller than the width of the insertion shaft 131 based on the pressing direction of the press. Therefore, when the base 200b is pressed toward the mold 100b by the press, the moving distance of the base 200b is limited while the hot plate 140b is in close contact with the mold 100b, that is, the rotating plate 130b. As a result, due to the gap formed between the base 200b and the bearing 310 , the contact between the base 200a and the bearing 310 is prevented, and thus the bearing 200a can be prevented from being damaged.
