[

  A vacuum forming tray mold 100 according to the present invention is provided with a film (not shown) for forming a substrate tray 10 on an upper surface thereof and is provided with a plurality of vacuum impressions formed on a plate surface of a vacuum forming tray mold 100 So that a film (not shown) is vacuum-formed into the shape of the substrate tray 10.

At this time, the vacuum forming tray mold 100 according to the present invention is rotatably coupled to the inner wall surface of the pocket forming groove 120 forming the substrate pocket 13, with the operating type stacking stopper ejecting unit 200. Thus, the laminated stopper 15 having a reverse gradient can be formed on the substrate tray 10 by vacuum molding. When the molded substrate tray 10 is separated from the substrate tray 10, So that interference with the discharge path of the substrate tray 10 is not caused.

Therefore, the depth d of the lamination stopper 15 of the substrate tray 10 can be deeply formed, and a plurality of the substrate trays 10 can be stably mounted up and down to prevent damage to the substrate There is an effect that can be done.

The mold body 110, the pocket forming groove 120, the edge forming face 130, and the reinforcing pocket forming groove 140 are integrally formed. The overall shape of the vacuum forming tray mold 100 may be variously provided corresponding to the substrate tray 10 to be manufactured.

A plurality of vacuum impressions (not shown) are formed through the plate surface of the vacuum forming tray mold 100. (Not shown) is provided with a plurality of corners and shapes of the pocket forming grooves 120 and the reinforcing pocket forming grooves 140 at positions where the corner areas and the shapes of the reinforcing pocket forming grooves 140 change, .

The pocket forming groove 120 is recessed at a predetermined depth from the surface of the mold body 110 so that the substrate pocket 13 is formed in the substrate tray 10. A plurality of step surfaces 121 are provided on the inner wall surface of the pocket forming groove 120. In the inner wall surface of the pocket forming groove 120, an injection unit receiving groove 123 is formed so as to be recessed inward to a certain depth.

As shown in FIG. 3, the operation type stacking stopper injection unit 200 is detachably coupled to the injection unit receiving groove 123. The injection unit receiving grooves 123 are formed in such a manner that the upper surface of the operating layered stopper injection unit 200 can be positioned on the same line as the upper surface of the mold body 110 .

The pocket forming groove 120 is provided with a laminated surface forming surface 123a which is stepped at a predetermined height from the bottom surface. The laminated surface forming surface 123a has a laminated surface 17 which is placed on the upper surface of the lower substrate tray 10a when the two substrate trays 10 and 10a are stacked up and down as shown in FIG. .

On the bottom surface of the pocket forming groove 120, an external fastening member insertion hole 125 into which the fastening member 127 is inserted is formed as shown in FIGS. The engaging member 127 is inserted through the outer fastening member insertion hole 125 and the actuating laminated stopper ejecting unit 200 can be detachably coupled to the vacuum forming tray mold 100. [

At the outer periphery of the mold body 110, the edge forming surface 130 is bent vertically. At this time, the border injection unit receiving groove 131 is formed in the boundary region between the mold body 110 and the edge molding surface 130. A frame operation stacking stopper injection unit 300 is coupled to the frame injection receiving slot 131 so that a frame stacking stopper (not shown) is formed on the substrate tray 10.

The shape of the rim unit receiving groove 131 is the same as that of the pocket forming groove 120 described above and is formed to have a size corresponding to the rim action type laminate stopper injection unit 300.

Fig. 5 is a perspective view showing the configuration of the operating laminated stopper ejecting unit 200, Fig. 6 is an exploded perspective view showing the configuration of the operating laminated stopper ejecting unit 200, Figs. 7 and 8 FIG. 5 is an exemplary view showing an operation process of the laminated stopper injection unit 200.

The operating type stacking stopper injection unit 200 is coupled to the injection unit receiving groove 123 so that a lamination stopper 15 having a reverse gradient is formed on the substrate tray 10. Further, the molded substrate tray 10 is stably separated from the vacuum forming tray mold 100.

The operating type stacked stopper injection unit 200 includes a unit casing 210 inserted into the injection unit receiving groove 123, a tilting member 220 coupled to the unit casing 210 so as to be raised and lowered, A lower rotation shaft 240 and a lower rotation shaft 250 for supporting the rotation member 220 in the unit casing 210 so that the rotation member 220 is lifted and rotated, And an elastic member 260 coupled between the elastic member supporting shaft 230 and the lower rotating shaft 240 to elastically support the pivoting member 220.

The unit casing 210 is formed in a rectangular housing shape corresponding to the injection unit receiving groove 123. Although the shape of the enclosure is rectangular, the shape of the enclosure is only one example. The shape of the enclosure may be variously changed depending on the shape of the substrate tray 10 to be formed, the size of the substrate W to be stacked, and the like.

The upper portion of the unit casing 210 is formed with a protrusion flow space 211 in which the backward projection 223 of the pivoting member 220 is rotatably received.

 The protrusion flow space 211 is formed so as not to generate interference in consideration of the turning radius of the backward gradient protrusion 223. In the protrusion flow space 211, a protrusion receiving surface 211a, which is stepped along the rim, is formed horizontally with a certain area. 5 (a), the projection receiving face 211a is seated with the reverse projection projection 223 horizontally arranged at the forming position. The projection seating surface 211a supports the lower portion of the rim of the backward gradient projection 223 to prevent the backward projection 223 from falling down into the unit casing 210 due to its own weight.

On the rear surface of the projection flow space 211, a projection rotation guide surface 213 is formed. The projection rotation guide surface 213 contacts and supports the lower end of the reverse gradient projection 223 when the reverse gradient projection 223 is in a horizontal forming position, as shown in FIG. 8, when the shaping of the substrate tray 10 is completed and the backward projection 223 is rotated to separate the substrate tray 10, the projection rotation guide surface 213 is rotated in the reverse- (223d) of the arm portion (223) so that the backward slope projection (223) can be pivoted.

A pair of elastic member support shaft insertion holes 215 are formed through both sides of the side wall of the unit casing 210. Both ends of the elastic member support shaft 230 are inserted into the pair of elastic member support shaft insertion holes 215 and fixed in position.

A pair of lower rotation shaft guide holes 216 are formed on the upper portion of the elastic member support shaft insertion hole 215. The lower rotation shaft guide hole 216 is formed in a slit shape having a predetermined length and both ends of the lower rotation shaft 240 are coupled. The lower rotation shaft guide hole 216 is formed to be inclined at an angle? The inclined direction of the lower rotation shaft guide hole 216 is formed upward in a direction away from the pocket molding groove 120.

A pair of upper rotation shaft guide holes 217 are formed on the lower rotation shaft guide hole 216. Both ends of the upper rotation shaft 250 are coupled to the upper rotation shaft guide hole 217. The upper rotation shaft guide hole 217 includes an inclined slit 217a formed to be inclined at a predetermined angle in parallel with the lower rotation axis guide hole 216 and a horizontal slit 217b extending in the horizontal direction from the upper end of the inclined slit 217a ).

The inclined slit 217a serves to guide the tilting member 220 in an upward tilting direction for separation, as shown in Fig. The horizontal slit 217b serves to fix the position of the upper rotation shaft 250 so that the pivoting member 220 guided in the upward direction is rotated.

The lower rotation axis guide hole 216 and the upper rotation axis guide hole 217 are formed in the form of slits having a predetermined length and the lower rotation axis 240 and the upper rotation axis 250 are inclined at a predetermined height, The substrate tray 10 can be more easily detached as compared with when the tiltable member 220 is rotated in place.

That is, at the time when the molding is completed, the substrate tray 10 remains attached to the vacuum forming tray mold 100. Even if the substrate tray 10 is lifted upwards in this state, the contact surfaces of the substrate tray 10 and the tiltable member 220 are stuck to each other by the tiltable member 220, so that the separation of the substrate tray 10 may not be easy .

The vacuum forming tray mold 100 of the present invention prevents the pivoting member 220 from being rotated by the pressure when the substrate tray 10 is lifted upward to prevent the rotation of the lower rotation axis guide hole 216 and the upper rotation axis guide hole 217 so that the adhesion surface between the substrate tray 10 and the tiltable member 220 drops and the attachment state can be released more quickly. This has the advantage that the separation of the substrate tray 10 can proceed more quickly.

On the other hand, as shown in FIG. 5 (b), a rear mounting hole 218 is formed in the rear surface of the unit casing 210. The rear mounting hole 218 serves to secure a space for the operator to assemble the upper rotation shaft 250, the lower rotation shaft 240, the elastic member support shaft 230, and the elastic member 260 to the unit casing 210.

The pivoting member 220 is disposed at a molding position protruding toward the pocket forming groove 120 to form the substrate tray 10 by vacuum compression as shown in Fig. 7, And is coupled to the unit casing 210 so as to be movable between a disengaged position where the substrate tray 10 is rotated by a predetermined angle after being upwardly inclined upward with respect to the grooves 120. [

The tilting member 220 includes a lifting plate 221 which is inserted into the unit casing 210 and a fixing member 220 which is integrally formed on the lifting plate 221 and forms a lamination stopper 15 on the substrate tray 10 And a slope projection 223.

The lifting plate 221 is inserted into the unit casing 210 and is coupled to the upper rotating shaft 250 and the lower rotating shaft 240 so that the rotating member 220 can be inclined upward. For this purpose, an upper rotating shaft insertion hole 221b and a lower rotation shaft insertion hole 221a are formed in the lifting plate 221 so as to be vertically aligned.

Here, the pivoting member 220 is rotated at a predetermined angle in a state where the lifting plate 221 is inserted into the unit casing 210. As shown in FIG. 8, when the tiltable member 220 is rotated, the lifting plate 221 contacts the inner wall surface of the unit casing 210 to limit the tilt angle.

The height h and the thickness d2 of the lifting plate 221 are preferably designed in consideration of the thickness d1 of the unit casing 210 and the maximum rotation angle of the desired reverse gradient projection 223 .

Since the gap between the substrate tray 10 and the backward projecting projection 223 is increased as the rotation angle of the backward projecting projection 223 is increased, it is easier to separate the substrate tray 10 and the backward projecting projection 223, So that it is desirable to design it at an appropriate rotation angle.

The backward slope projection 223 is integrally formed on the upper portion of the lift plate 221 so that the lamination stopper 15 is formed on the substrate tray 10. The backward projection 223 is formed to protrude toward the pocket forming groove 120 so that the substrate tray 10 is formed on the substrate tray 10.

The backward projection 223 is formed so as to have a reverse gradient from the upper horizontal surface 223a and the upper horizontal surface 223a provided horizontally with the mold body 110 so that the laminate stopper 15 is formed on the substrate tray 10 And a stationary blade 223c formed on both sides of the stationary blade 223c to extend in the horizontal direction by a predetermined area and to be seated on the projection seating surface 211a.

The upper horizontal surface 223a is horizontally formed on the upper side of the reverse gradient projection 223. At this time, the width W2 of the upper horizontal surface 223a is formed to be longer than the width W1 of the unit casing 210 by a predetermined length. 7, the upper horizontal surface 223a is protruded toward the pocket forming groove 120 at a predetermined length compared to the unit casing 210 at the forming position.

The inverted rear surface 223b is formed to be inclined at a predetermined angle so as to have a reverse gradient from the bottom of the upper horizontal surface 223a. 7, when the substrate tray 10 is vacuum-adsorbed, the laminated stopper 223a having a reverse gradient from the end of the upper horizontal surface 223a to the laminated surface forming surface 123a, (15) are formed.

The shape of the lamination stopper 15 may be formed as a slope having a reverse gradient or a curved face having a reverse gradient. The greater the difference between the upper horizontal surface 223a and the width W1-W2 of the unit casing 210, the deeper the depth of the laminated stopper 15 (d in Fig. 1) becomes. It is preferable that the recessed depth d of the laminated stopper 15 is formed to a depth that can stably be mutually stuck when the plurality of substrate trays 10 are stacked up and down.

The stationary blade 223c is extended to both sides of the backward projection 223 and fixed on the projection receiving surface 211a of the unit casing 210 as shown in Fig. Accordingly, the upper horizontal surface 223a can be stably maintained in a horizontal state with the upper surface of the mold body 110. [

On the other hand, a recessed groove 223d formed inwardly recessed is provided on the back surface of the reverse gradient projection 223. The recessed groove 223d connects between the reverse gradient projection 223 and the lift plate 221 and contacts the projection rotation guide surface 213 at the separation position as shown in Figure 7 and the reverse gradient projection 223 is rotated .

That is, the depression groove 223d corresponds to the projection rotation guide surface 213 so that the turning radius of the backward slope projection 223 does not interfere with the projection rotation guide surface 213 when the backward slope projection 223 is rotated to the separation position Respectively. The recessed groove 223d is brought into contact with the projection rotation guide surface 213 when the reverse projection projection 223 is pivoted about the upper rotation axis 250, The projection 223 is rotated.

The elastic member support shaft 230 is inserted through the unit casing 210 to support the lower end 261 of the elastic member 260. Both ends of the elastic member support shaft 230 are inserted into the elastic member support shaft insertion hole 215 at the lower end of the unit casing 210 and fixed in position.

The lower rotating shaft 240 is inserted through the unit casing 210 and the pivoting member 220 to support the pivoting member 220 so as to be inclined. The lower rotating shaft 240 is inserted into the lower rotating shaft guide hole 216 of the unit casing 210 and the lower rotating shaft insertion hole 221a of the lifting plate 221.

The lower rotating shaft 240 is moved up and down along the lower rotating shaft guide hole 216 by the pressure that the substrate tray 10 is moved upward when the substrate tray 10 is separated so that the rotating member 220 is moved up and down .

An upper end 263 of the elastic member 260 is engaged with the lower rotating shaft 240 so that an elastic force of the elastic member 260 is applied to the rotating member 220.

The upper rotation shaft 250 is inserted into the unit casing 210 and the pivoting member 220 to support the pivoting member 220 in such a manner that the pivoting member 220 is not only raised and lowered but also tilted. The upper rotation shaft 250 is inserted into the upper rotation shaft guide hole 217 of the unit casing 210 and the upper rotation shaft insertion hole 221b of the lift steel plate 221.

The upper rotary shaft 250 is moved obliquely along the inclined slit 217a of the upper rotary shaft guide hole 217 by the pressure that the substrate tray 10 is moved upward when the substrate tray 10 is separated, 217b.

The elastic member 260 applies an elastic force so that the tiltable member 220, which is raised and rotated at the separation position, returns to the forming position. The lower end 261 of the elastic member 260 is fixed to the elastic member support shaft 230 and the upper end 263 of the elastic member 260 is fixed to the lower rotation axis 240.

The elastic member 260 maintains the compressed state at the forming position as shown in FIG. 7, and when the pivoting member 220 is raised and rotated to the separated position as shown in FIG. 8, do. Accordingly, the elastic member 260 exerts an elastic force in a direction in which the elastic member 260 is compressed to be initially compressed, that is, in a direction in which the pivoting member 220 is lowered.

The tilting member 220 is returned to the forming position by the elastic force of the elastic member 260 when the substrate tray 10 is completely separated and the pressing force against the reverse gradient projection 223 is released.

The frame-operating type stacking stopper discharging unit 300 coupled to the frame forming surface 130 has the same shape and configuration as the operating type stacking stopper discharging unit 200 coupled to the pocket forming groove 120, The sizes may be different. That is, as shown in FIGS. 2 and 4, the frame-operating type stacking stopper ejecting unit 300 can be formed relatively larger than the operating type stacking stopper ejecting unit 200.

A process of forming the substrate tray 10 using the vacuum forming tray mold 100 according to the present invention having such a configuration will be described with reference to FIGS. 2 to 8. FIG.

The vacuum forming tray mold 100 includes an operation type stacking stopper ejecting unit 200 and a frame operation stacking stopper ejecting unit 300 on the pocket forming groove 120 and the edge forming surface 130 of the mold body 110, . The operating type stacking stopper injection unit 200 is fixed to the mold body 110 by the fastening member 127.

A film for manufacturing a substrate tray (not shown) is placed on the upper surface of the vacuum forming tray mold 100 and a plurality of vacuum impressions (not shown) formed on the surface of the mold body 110 are vacuum- The film (not shown) is sucked and vacuum-formed corresponding to the inner shape of the vacuum forming tray mold 100.

At this time, the operating type laminated stopper injection unit 200 inserted into the injection unit receiving groove 123 of the pocket molding groove 120 as shown in Fig. 7 is arranged in the molding position. That is, the upper horizontal surface 223a of the backward projecting projection 223 is positioned horizontally with the mold body 110 and is disposed so as to protrude a predetermined length toward the pocket forming groove 120, and the backward projecting surface 223b is directed downward .

The elastic member 260 maintains a compressed state between the elastic member supporting shaft 230 and the lower rotating shaft 240 and the lifting plate 221 is accommodated in the unit casing 210.

When vacuum pressure is applied in this state, a substrate pocket 13 and a laminated seating surface 17 are formed in the substrate tray 10 and a reverse gradient connecting the tray body 11 and the laminated seating surface 17 A laminated stopper 15 is formed.

When the formation of the substrate tray 10 is completed, the substrate tray 10 is moved upward and separated from the vacuum forming tray mold 100. The lamination stopper 15 formed on the substrate tray 10 is moved upward and presses the backward projection protrusion 223 protruding into the pocket forming groove 120. As a result, By the pressing of the lamination stopper 15, the backward slope projection 223 is subjected to an upward force as shown in Fig.

The upper and lower rotating shafts 250 and 240 integrally formed on the lower portion of the backward slanting projection 223 are formed in the upper and lower rotating shaft guide holes 217 and 216, (Not shown).

The tiltable member 220 which is raised obliquely by the guide of the upper rotation shaft guide hole 217 and the lower rotation shaft guide hole 216 is rotated by the upper rotation shaft 250 inserted into the horizontal slit 217b by the pressing force of the substrate tray 10, As shown in FIG.

The maximum rotation angle of the tiltable member 220 is limited to an angle at which the lifted steel plate 221 contacts the inner wall surface of the unit casing 210. As a result, the backward projection 223 is retracted backward in the inclined direction and is rotated at a predetermined angle, thereby eliminating the configuration for interfering with the movement path of the lamination stopper 15. [ Particularly, since the backward projection 223 is retracted backward and the contact state with the substrate tray 10 is released and separated, the separation of the substrate tray 10 can be performed more easily, and the depth d of the stacking stopper 15 Can be easily separated from the vacuum forming tray mold 100. [

8, the elastic member 260 coupled between the elastic member supporting shaft 230 and the lower rotating shaft 240 is stretched when the pivoting member 220 is raised and rotated to the separated position. When the substrate tray 10 is completely separated from the vacuum forming tray mold 100 and the pressing force of pressing the backward projecting projection 223 disappears, the tilting member 220 is retracted again by the elastic force of the elastic member 260 to be compressed 7 to the forming position.

The operation of the operating type stacked stopper injection unit 200 is also applied to the frame operation type stacked stopper injection unit 200 as well.

As described above, in the vacuum forming tray mold according to the present invention, the operating type stacking stopper ejecting unit is coupled to the inner wall surface of the pocket forming groove. The operating type stacking stopper ejecting unit is provided with a pivoting member rotatably provided with a backward projection protruding and formed with a predetermined length toward the pocket forming groove.

When the substrate tray is formed, the pivoting member is provided so that a backward projection protrudes toward the pocket forming groove to form a lamination stopper on the substrate tray. When the formed substrate tray is separated in the upward direction, the backward projecting projection is pressed by the stacking stopper of the substrate tray so that the pivoting member is raised and rotated in the direction away from the pocket forming groove.

Since the tilting member is raised and retracted from the substrate tray, it is possible to easily separate the substrate tray and the reverse gradient protrusion from the substrate tray on which the substrate tray and the reverse gradient projection are fixed immediately after the formation of the substrate tray.

Further, the structure in which the pivoting member is rotated at a predetermined angle to interfere with the separation of the lamination stopper disappears.

As a result, the depression depth of the lamination stopper can be made large, and when a plurality of substrate trays are stacked on top and bottom, they can be stacked without overlapping each other. As a result, damage to the substrate can be prevented.
