In view of the above, it is an object of the present invention to provide a conveying apparatus capable of conveying a molding object and suppressing a deviation of a mounting position of a molding object mounting portion of a molding die, even if a variation in the outer dimensions of the molding object is caused. A resin molding device and a resin molded article production method. [Technical means to solve the problem]

In the conveyance device of the present invention, the object to be conveyed is a device for conveying a molding object to a molding die of a resin molding device, and includes a molding object holding portion, and the molding object holding portion includes a molding object. a mounting portion that mounts the object to be molded, and a plurality of edge limiting members that are provided on a periphery of the object to be placed or outside of the object to be placed to limit the The member of the edge of the object to be molded is movable in the direction of the inside of the object to be placed.

The resin molding apparatus according to the present invention includes: the conveying device; and a molding die including a first mold having a molding target mounting portion to which the molding object is attached, and a first portion disposed to face the first mold 2 mode.

In the method of producing a resin molded article of the present invention, the object to be molded is placed on the object to be placed, and the object to be molded is placed on the object to be placed in the object to be held of the conveyance device, and is placed on the object to be molded. a plurality of end edge restricting members that restrict a peripheral edge of the object to be placed or an outer side of the object to be molded and that restrict an end edge of the object to be molded toward the object to be placed The object to be molded is held in the object to be molded, and the object to be molded is carried in the step of moving the object to be placed and the object to be molded of the molding die. The object to be held is moved by the alignment method, and after the object to be molded is attached to the object mounting portion, the object holding portion is moved to the outside of the forming die. The molding die includes a first mold having the molding target mounting portion to which the molding object is attached, a second mold disposed to face the first mold, and a resin molding step. After one mold and the second mold clamping, the object of the molded resin molding. [Effects of the Invention]

According to the present invention, even if a variation occurs in the outer dimensions of each of the objects to be molded, it is possible to convey the object to be molded, and it is possible to suppress the deviation of the mounting position of the object to be attached to the molding die.

In the transport apparatus, the resin molding apparatus, and the resin molded product manufacturing method of the present invention, the object to be molded is placed on the object to be molded, and the edge regulating member is placed inside the object placing unit. The direction is moved, whereby the object to be molded is held by the object to be held. By using the movable edge regulating member in this manner, the object to be molded can be held even if the outer dimension of the object to be molded is deviated. In addition, it is possible to prevent the position regulating member from being displaced from the position where the object to be molded is attached to the object to be molded by moving the edge regulating member so as to reduce the gap between the edge regulating member and the object to be molded.

The shape of the edge limiting member is not particularly limited. Further, the type and shape of the object to be molded are also not particularly limited. Examples of the type of the object to be molded to which the present invention can be applied include a semiconductor wafer, a circuit board, a lead frame, a glass substrate, a metal substrate, and the like. Examples of the shape of the object to be molded include a circle, a rectangle, and other polygonal or elliptical shapes. Wait.

The method of producing a resin molded article of the present invention may further include: a step of holding the object to be carried out at the time of carrying out, and after the resin forming step, the first mold and the second mold are opened to cause the object to be molded to be loaded The object to be held is moved so that the position of the portion is aligned with the object to be attached, and the object to be molded attached to the object mounting portion is placed in the resin. The object to be placed, the end edge regulating member is moved in the direction of the inside of the object placing portion, thereby holding the object to be molded in the object holding portion; and moving out In the step, the formed object holding portion is moved to the outside of the forming mold.

The variation in the outer dimensions of the object to be molded is caused by, for example, the following reasons, in addition to the processing error occurring during the above processing. An example of the first cause is thermal expansion due to the object to be molded. At the time of resin molding, the first mold and the second mold are heated to a temperature at which resin molding can be performed. Therefore, the temperature of the object to be molded becomes higher than the temperature before molding immediately after the resin molding. In order to improve the production efficiency, it is necessary to remove the molded object from the object to be molded portion and carry it out to the outside of the molding die before the temperature is sufficiently lowered. Therefore, when the object to be molded is carried out, it is thermally expanded compared with the time of loading, and is carried in. The outer dimensions are different from those when moving out. In addition, when the material of the object to be molded is different, the coefficient of thermal expansion is different. Therefore, the size of the object to be molded differs depending on the material of the object to be molded. An example of the second cause is a problem that occurs when the overmolding described below is performed. The overmolding is performed by molding the resin until it is outside the object to be molded, and when a fan-out type package in which wiring or an input/output terminal is provided outside the resin-sealed wafer is performed. Since the shape of the object to be molded which has been subjected to the secondary molding is larger than the original shape, the outer dimensions of the object to be molded are different from those at the time of carrying in. According to the transport apparatus, the resin molding apparatus, and the resin molded product manufacturing method of the present invention, the object to be molded can be held in any of the first and second causes, and the object to be molded can be suppressed. The position at which the object is attached to the mounting portion of the object to be molded is deviated.

In addition, in the example of the first cause and the second cause, when the object to be molded is carried into the molding die and the object to be molded is unloaded from the molding die, the outer dimensions of the object to be molded are different. In the resin molding apparatus described above, the conveyance device (unloader) for carrying out the conveyance device (shipper) for loading is provided separately, and the cost of the resin molding device increases. On the other hand, in the conveying apparatus, the resin molding apparatus, and the resin molded product manufacturing method of the present invention, the same conveying apparatus is used at the time of loading and at the time of carrying out, so that the cost can be suppressed.

In the conveying apparatus and the resin molding apparatus of the present invention, it is preferable that the object to be held further includes a biasing member that faces the plurality of edge limiting members in the direction (formation object) The force is applied in the direction of the inside of the placing portion. Further, in the method of producing a resin molded article of the present invention, it is preferable that the plurality of end edge restricting members are used by the biasing member in a state where the object to be molded is held by the object to be molded holding portion Apply force in the direction. By holding the object to be molded in the object to be held, the object to be molded is held by the plurality of edge limiting members that are biased toward the inside of the object to be placed by the biasing member. Therefore, the object to be molded can be held more stably. For example, when the object to be held and the object to be held are close to the first mold and the second mold that have been heated, the object to be held and the object to be molded correspond to the respective coefficients of thermal expansion. Produces expansion. Even in such a case, it is possible to stably hold the object to be molded by biasing the plurality of end edge regulating members in the direction of the inside of the object to be placed.

In the conveying apparatus of the present invention, a configuration may be employed including: a plate-shaped rotating member that rotates about a rotation center; and an end edge restricting member that guides an elongated hole on the rotating member with respect to the plurality of the end edges One of each of the restricting members is provided for the end edge restricting member to be inserted, and the end edge restricting member is movable; and the end edge restricting member moving restricting portion is opposed to the plurality of the end edge restricting members Each of them is provided one, and a direction in which the end edge restricting member can move is restricted to a straight line passing through the end edge restricting member and the rotation center. Such a transfer device can be used in the resin molding device and the resin molded article production method of the present invention.

According to the configuration having the rotating member, the end edge restricting member guide long hole, and the end edge restricting member movement restricting portion, the end edge restricting member guides the long hole in the end edge restricting member by rotating the rotating member about the rotation center The position changes, and along with this, the end edge restricting member moves on a straight line passing through the end edge restricting member and the rotation center in such a manner that the distance from the rotation center changes. Thereby, the edge regulating member can be moved in the direction of the inside of the object placement portion or in the opposite direction of the direction.

The end edge restricting member guide long hole can be configured to connect a point at a center line in the width direction of the center in the width direction of the end edge restricting member and a distance from the center of rotation to be different from the point A point on the center line in the width direction is different from a distance from the center of rotation. Thereby, when the end edge restricting member moves between the two points in the leading edge of the end restricting member by the rotation of the rotating member, the distance between the two points and the center of rotation is different from each other, and thus the end The rim restricting member moves on a straight line passing through the end edge restricting member and the rotation center. The term "width direction" as used herein refers to a point at which the edge regulating member guides a certain point on the outer edge of the long hole and the inside of the long hole is guided by the end edge regulating member from the point. The direction of the other point on the outer edge.

It is possible to adopt a configuration in which the end edge restricting member guides the long hole such that a distance from a point on the center line in the width direction to the center of rotation increases as the point increases from one end of the width direction center line toward the other end. The way is formed. Thereby, when the rotating member is rotated in either a clockwise or counterclockwise direction in a plan view, the end edge restricting member moves in a manner close to the center of rotation, and when the rotating member is rotated in the reverse direction, the end edge restricting member Move away from the center of rotation.

In the conveying apparatus and the resin molding apparatus including the urging member, it is preferable to further include a urging member control unit that starts/stops (ON/OFF) the actuation of the urging member. . In the method of holding the object to be molded (and the step of holding the object to be carried out at the time of carrying out) in the method of manufacturing the resin molded article using the operation of the urging member, it is preferable to form the object to be molded. Before the object to be placed is placed on the object to be placed, the operation of the urging member is stopped, and after the object to be molded is placed on the object to be placed, the urging member is placed The action begins. Therefore, when the object to be molded is placed on the object to be molded, the plurality of edge regulating members are not biased by the biasing member in the direction of the inside of the object placing portion, so that it is possible to secure The forming object is placed on the forming object placing portion while the gap between the plurality of edge limiting members and the object to be molded is at the same time.

In the conveying apparatus and the resin molding apparatus of the present invention, it is preferable that all of the plurality of end edge regulating members are movable in the direction in conjunction with each other. Further, in the method of producing a resin molded article of the present invention, preferably, when the plurality of edge regulating members are moved in the direction, all of the plurality of edge limiting members are interlocked Move in the direction described. By this, it is possible to hold the object to be molded in the vicinity of the center of the object to be held, and it is possible to improve the accuracy of the mounting position of the object to be attached.

It is preferable that one of the plurality of end edge restricting members is provided at a position corresponding to a slit (notch) provided on the forming object placed on the forming object mounting portion. . By aligning the position of the slit with the end edge regulating member, the object to be molded is placed on the object to be molded, and the direction of the object to be molded on the object to be placed can be determined. .

A hole 231 through which the shaft body 221 is inserted is provided at the center of the turret 23, and the turret 23 is rotated about the shaft body 221 as a center of rotation.

Ten end edge restricting member guiding recesses 222 are provided on the lifting frame 22, nine of which are disposed at an inner side of the outer circumference of the lifting frame 22 at intervals of 40° along the circumference of the outer contour (Fig. 2(c) Figure 3 (a)). The remaining one end restricting member guiding recess 222A is disposed between the two adjacent end edge restricting member guiding recesses 222, and is disposed slightly inside than the nine end restricting member guiding recesses 222 At the office. The position in the circumferential direction of the edge regulating member guiding recess 222A is set as long as the position of the slit (notch) provided in the forming object is desired when the object to be molded is attached to the forming die (the slit is intended to face) The direction can be arbitrarily set. The vicinity of the lower surface of the cylindrical end edge regulating member accommodating portion 272 (described later) of the one end edge regulating member 27 is held in one end edge regulating member guiding concave portion 222 (including the end edge regulating member guiding concave portion 222A). The distance between both ends in the extending direction of the straight line (dotted line in FIG. 3( a )) intersecting the center of rotation of the edge restricting member guiding recess 222 is set larger than the diameter of the end edge restricting member accommodating portion 272 . Further, the width of the end edge restricting member guiding recess 222 in the direction perpendicular to the straight line is set to be shorter than the distance, and is slightly larger than the diameter of the end edge restricting member accommodating portion 272 so that the end edge restricting member accommodates The portion 272 hardly moves in a direction perpendicular to the straight line, and is movable in the direction of the straight line. Thereby, the end edge restricting member 27 is restricted in such a manner as to be guided by the end edge restricting member guiding recess 222 to move in the direction in which the straight line extends. The end edge restricting member guiding recess 222 corresponds to the end edge restricting member movement restricting portion.

The turret 23 has a plate shape and is provided with ten end edge restricting members to guide the long holes 232, nine of which are disposed at an inner side of the outer periphery of the turret 23 at intervals of 40° along the circumference of the outer contour (Fig. 3(b)). The remaining one end edge restricting member guide long hole 232A is disposed between the two adjacent two end edge restricting member guide long holes 232, and is disposed to guide the long hole 232 than the nine end edge restricting members. Slightly behind the inside of the turret 23. In each of the end edge restricting member guide long holes 232, each of the end edge restricting members 27 held in the end edge restricting member guiding concave portion 222 of the lift frame 22 is inserted, in which the end edge restricting member guide long hole 232A is inserted. End edge restricting member 27A. The end edge restricting member guide long hole 232 has a width slightly larger than the diameter of the end edge restricting member accommodation portion 272 in a direction in which the straight line intersecting the center of rotation extends. The end edge restricting member guides the trajectory drawn by the end edge restricting member body 271 in the long hole 232 during the movement of the inserted end edge restricting member 27 in the longitudinal direction of the end edge restricting member guiding long hole 232 ( The thick line in Fig. 3(b) is defined as "the center line in the width direction". The left end toward the right end from the center line in the width direction (here, the left and right sides are defined when the end edge restricting member guide long hole 232 is located above the center of rotation as shown in FIG. 3(b)) The end edge restricting member guides the distance between the long hole 232 and the center of rotation of the turret 23 (the center of the hole 231) (the left end of the end edge restricting member guide long hole 232 is set to r ₁ and the right end is set to r ₂ . The end of the end edge restricting member guiding long hole 232 is set to "r ₁ end", and the right end is set to "r ₂ end") to gradually decrease (thus r ₁ > r ₂ ), with respect to the center of rotation The end edge restricting member guides the long hole 232 obliquely with the tangential direction of the center of the circle. The nine end edge restricting members other than the end edge restricting member guiding long holes 232A guide the long holes 232 to have the same shape and are disposed at the same slope with respect to the tangential direction. The end edge restricting member guides the long hole 232A from the left end toward the right end of the center line in the width direction (the definition is the same as the case where the other end edge restricting member guides the long hole 232, and the end edge restricting member depicted in FIG. 3(b) guides the long hole The position of the hole 232A is from the right end toward the left end, and the distance from the center of rotation of the turret 23 is gradually reduced from r ₃ to r ₄ (r ₃ >r ₄ , r ₁ > r ₃ , r ₂ > r ₄ ) Tilting with respect to the tangential direction. The left end of the end edge regulating member guide long hole 232A is set to "r ₃ end", and the right end is set to "r ₄ end".

With such a configuration, when the turret 23 is rotated counterclockwise in the plan view (hereinafter, "counterclockwise" and "clockwise" are defined in a plan view), the position of each end edge restricting member 27 is guided from the end edge restricting member. The r ₁ end side in the long hole 232 is moved to the r ₂ end side (moving from the r ₃ end side to the r ₄ end side in the end edge restricting member guiding long hole 232A), whereby the end edge restricting member 27 (27A) The distance from the center of rotation gradually decreases toward the inside of the object to be placed portion 25 (the direction in which the center of rotation exists) (FIG. 4(a)). On the other hand, when the turret 23 is rotated clockwise, the position of each end edge restricting member 27 is moved from the r ₂ end side in the end edge restricting member guide long hole 232 to the r ₁ end side (in the end edge restricting member guide) The long hole 232A is moved from the r ₄ end side to the r ₃ end side, and the distance between the end edge regulating member 27 (27A) and the rotation center is gradually increased to move toward the outside of the object placement portion 25. (Fig. 4(b)). Here, the nine end edge restricting members guiding the long holes 232 other than the end edge restricting member guiding long holes 232A are provided in the same shape and at the same inclination with respect to the tangential direction, thereby being placed on the object to be formed In the movement of the inner direction and the outer direction of the portion 25, a state in which the distance from the center of rotation is equal is maintained between the nine end edge regulating members 27 other than the end edge regulating member 27A. The end edge restricting member 27A moves in a manner closer to the distance from the center of rotation than the other end edge restricting members 27.

The lifting frame 22 is provided with a torsion spring 234 that biases the turret 23 in a counterclockwise direction. Thereby, the edge regulating member 27 is biased in the direction of the inside of the object to be mounted portion 25. The torsion spring 234 and the turret 23 correspond to the urging member. Further, the urging member is not limited to the torsion spring, and an air cylinder or a servo motor or the like that rotates the turret 23 counterclockwise can be used.

A slit 235 is provided at the outer edge of the turret 23. Further, a stopper 225 is provided on the outer edge of the crane frame 22. The stopper 225 is biased toward the slit 235 side by a spring, and is disposed at a position where the turret 23 is engaged with the slit 235 when the turret 23 is rotated clockwise by one full turn. As described above, the turret 23 is biased in the counterclockwise rotation by the torsion spring 234 (that is, the end edge regulating member 27 is moved in the direction in which the inside of the object placement portion 25 is moved). The movable member 225 is engaged with the slit 235, and can be stopped in a state where the turret 23 is rotated clockwise by one full turn (that is, the end edge regulating member 27 is moved in the direction of the outside of the forming object mounting portion 25). Further, by disengaging the engaged stopper 225 from the slit 235, the turret 23 is rotated counterclockwise by the action of the torsion spring 234. The stopper 225 and the slit 235 correspond to an urging member control unit that starts/stops the actuation of the urging member. The position or direction of the stopper 225 is not particularly limited.

The non-rotating frame 24 and the forming object placing portion 25 are provided with end edges having the same planar shape as the end edge regulating member guiding concave portion 222 at positions corresponding to the end edge regulating member guiding concave portions 222 of the lifting frame 22, respectively. The restricting member passes through the hole 242 and the end edge restricting member through the hole 252 (Fig. 2(c)).

The elevating mechanism 26 is a mechanism that is provided on the upper surface of the chassis 21 and that raises and lowers the crane 22 . As the lift frame 22 rises and falls, the turret 23, the non-turret 24, and the object placement portion 25 provided on the lift frame 22 also rise and fall.

As shown in FIG. 5, the end edge regulating member 27 has an end edge regulating member body 271, the above-described cylindrical end edge regulating member housing portion 272, and an elastic member 273. The end edge regulating member body 271 is a cylindrical member having a diameter smaller than that of the end edge regulating member housing portion 272. The elastic member 273 supports the lower end of the end edge restricting member body 271 and is provided at the bottom in the end edge restricting member housing portion 272. When the end edge restricts the upper end of the member body 271, the elastic member 273 is compressed and the upper end is lowered. When the pressing is released, the elastic member 273 is elongated, and the upper end is returned to the original position. When the upper end of the end edge restricting member body 271 is located at the original position, the upper end protrudes through the hole 252 through the end edge restricting member to be higher than the upper surface of the forming object placing portion 25. On the other hand, the upper end of the edge regulating member accommodation portion 272 is located lower than the upper surface of the object placement portion 25 . The molding target placing portion 25 and the end edge regulating member 27 are combined to constitute a molding target holding portion 28.

Four plate-shaped positioning members 2241 to 2244 for aligning the position of the conveying device 20 and the upper mold 151 in the lateral direction in the forming mold 15 are provided in the lifting frame 22. The positioning member 2241 to the positioning member 2244 are disposed such that when the conveying device 20 is raised from below the upper mold 151, each of the positioning members 2241 to 2244 abuts on the four side faces of the upper mold 151.

(2) Operation of the conveyance device and the resin molding apparatus of the present embodiment and the resin molded article manufacturing method of the present embodiment Next, the conveying device 20 and the resin molding device 10 are shown in FIGS. 6(a-1) to 8(b). The operation and the embodiment of the method for producing a resin molded article of the present invention will be described. In addition, in FIGS. 7(a) to 7(f) and FIGS. 8(a) and 8(b), the resin molding apparatus 10 is seen from the right direction of FIG.

First, the transport device 20 is moved to the attaching and detaching position of the object to be molded along the rail 16 provided in the resin molding apparatus 10 that is engaged with the convex rail 211 provided on the chassis 21.

Next, the turret 23 is rotated clockwise to engage the stopper 225 with the slit 235. Thereby, the edge regulating member 27 moves to the outside of the object to be mounted 25 (FIG. 6 (a-1), FIG. 6 (a-2)). In the above-described state, the disk-shaped object to be molded (semiconductor wafer) S is disposed inside the region surrounded by the nine end edge regulating members 27 in the upper surface of the object to be placed 25 . Here, a slit SC is provided at the outer edge of the object S to be aligned, and the position of the slit SC is aligned with the position of the edge restricting member 27A (Fig. 6 (a-1)). In the above state, each of the end edge regulating members 27 (including the end edge regulating members 27A) does not abut against the outer edge of the forming object S.

Next, the stopper 225 is disengaged from the slit 235, and the turret 23 is rotated counterclockwise by the action of the torsion spring 234. Thereby, the ten end edge regulating members 27 move in the direction of the inside of the object to be mounted portion 25 in conjunction with each other. Further, by the end edge restricting member body 271 of the end edge restricting member 27 abutting against the outer edge of the forming object S, the rotation of the turret 23 is stopped (thus, the turret 23 does not necessarily rotate one full turn counterclockwise), and the forming object The object S is held by the object placement unit 25 (FIG. 6 (b-1) and FIG. 6 (b-2)). In this way, the plurality of end edge regulating members 27 are in contact with each other in the outer edge of the object to be placed 25, and the object S is held in the center of the object placing portion 25, thereby suppressing the object S to be formed. The position is deviated. In addition, even if there is a variation in the outer dimensions of the object S due to a machining error or the like, the edge regulating member 27 can move to hold the object S, and the deviation of the mounting position can be suppressed. Further, the end edge regulating member 27A disposed at the position of the slit SC in the end edge regulating member 27 is engaged with the slit SC, whereby the position of the forming object S in the circumferential direction is also defined, so that the forming object can be specified. The direction of the object S to be formed on the object placing portion 25. Thus, the forming object holding step at the time of loading is completed.

After the molding object S is placed on the molding target placing portion 25, the conveying device 20 is moved between the upper mold 151 and the lower mold 152 along the rail 16 so that the molding target placing portion 25 is The position of the object to be attached 1511 of the upper mold 151 is aligned (Fig. 7(a)).

At the position, the elevating mechanism 26 raises and lowers the portion of the object to be placed 25 that is higher than the elevating frame 22, and the object S placed on the object to be placed 25 is brought into contact with The object mounting portion 1511 is formed (Fig. 7(b)). At this time, the upper end of the edge regulating member main body 271 is in contact with the forming object mounting portion 1511 before the forming object S, and thereafter, when the lifting mechanism 26 is further raised, the elastic member 273 is compressed, thereby forming the object to be molded. The relative position of the upper surface of the placing portion 25 is lowered. Therefore, the object to be molded S can be brought into contact with the object to be molded 1511 without being interfered by the edge limiting member 27 .

When the object S is in contact with the object to be molded 1511, the gas is sucked from the gas suction hole 1512 by the vacuum pump, whereby the object to be molded is attached to the object mounting portion 1511. The gas is continuously sucked from the gas suction hole 1512 until the stop time described later. Then, the turret 23 is rotated clockwise to move the edge regulating member 27 toward the outside of the object mounting portion 25, and the object to be placed 25 is lowered by the elevating mechanism 26, and then the conveying device is moved. 20 moves to the outside of the forming die 15 (Fig. 7(c)). Thus, the forming object carrying step is completed.

Then, the release film F is laid on the inner surface of the chamber C of the lower mold 152 by a release film laying mechanism (not shown), and then the resin material P containing the thermosetting resin is supplied by a resin material supply mechanism (not shown). It is supplied into the chamber C (Fig. 7 (d)). The release film laying mechanism and the resin material supply mechanism have been widely used in the conventional resin molding apparatus, and thus detailed description thereof will be omitted. The resin material P is melted in the chamber C by the heat supplied from the heater 142.

After the resin material P in the chamber C is melted, the movable platen 121 is raised by the crank link 113. Thereby, the lower mold 152 on the movable platen 121 abuts against the upper mold 151 and presses the upper mold 151, so that the upper mold 151 is fixed to the fixed platen 122, whereby the upper mold 151 is closed with the lower mold 152 ( Figure 7 (e)). After a predetermined period of time has elapsed in the above state, the resin material P is cured, and a resin molded article PS obtained by resin molding the surface of the object S to be formed is obtained. At this point, the resin forming step is completed.

Thereafter, the movable platen 121 is lowered by the crank link 113 to mold the molding die 15 (Fig. 7(f)). Then, the conveyance device 20 is conveyed between the upper mold 151 and the lower mold 152 to align the position of the molding target mounting portion 25 with the molding target mounting portion 1511 of the upper mold 151 (FIG. 8(a)). . Further, the end edge regulating member 27 is moved to the outside of the forming target placing portion 25 by rotating the turret 23 in the right direction (FIG. 6 (a-1), FIG. 6 (a-2)). When the object to be placed 25 or the like is raised by the elevating mechanism 26, the upper surface of the object mounting portion 25 is brought into contact with the lower surface of the resin molded article PS (Fig. 8(b)). Then, the suction of the gas from the gas suction hole 1512 is stopped, and the object placement portion 25 or the like is lowered by the elevating mechanism 26.

Further, by rotating the turret 23 counterclockwise, the edge regulating member 27 is moved toward the inside of the object placement portion 25 (Fig. 6 (b-1), Fig. 6 (b-2)). The outer edge of the resin molded article PS. By this, the resin molded article PS which is resin-molded on the surface of the object to be molded S is held in the state of holding the object holding portion 28 . At this time, the resin molded article PS is not sufficiently cooled, and the outer size may be larger than the molded object S before the resin molding. However, even in this case, the resin can be moved by the edge regulating member 27 . The resin molded article PS is held. In the same manner, the resin molded product PS which is formed by the resin molding to the outside of the outer periphery of the object S can be held by the edge regulating member 27 . Thus, the forming object holding step at the time of carrying out is completed.

Thereafter, the conveying device 20 is moved to the outside of the forming die 15 (the carrying-out step). Then, in a state in which the end edge regulating member 27 is moved to the outside of the object to be placed 25 by rotating the turret 23 to the right, the resin molded article PS is removed from the object to be placed 25, and The manufacture of this one resin molded article PS is completed.

The operation of the conveyance device 20 described above, specifically, the rotation of the turret 23, the movement along the rail 16, and the lifting and lowering of the object placement portion 25 by the elevating mechanism 26 can be automatically performed using the power. It can also be done manually by the operator.
