Therefore, the following technology is proposed: the glue sleeve block provided with the glue sleeve is set up and down, the glue sleeve block is used to press the end of the workpiece, and the resin passage (bridge gate) is formed on the surface of the block. gate): Bridge section).

For example, in order to prevent the plastic sealing resin from winding to the end face of the workpiece, it is necessary to position the end face of the workpiece with the opposite mold end face, and eliminate the generation of gaps as much as possible. Therefore, the following technology is proposed in which one end surface of a rectangular strip substrate as a workpiece is pushed by a push block, and the opposite end surface touches and aligns the end surface of a pot insert (see Patent Document 1 : Japanese Patent Laid-Open No. 2015-51557).

In this way, the unloader body 5a enters the opened plastic molding mold 1, the remaining material holding block 5b attracts and retains the excess resin R2 supported by the feeding sleeve block 3a, the pair of workpiece recovery parts 5d hold the formed workpiece W, and The sliding mechanism 5e is used to move away from each other to a position where it does not interfere with the rubber feeding sleeve block 3a, and the formed workpiece W is carried out. Thereby, the workpiece recovery part 5d carries out the molded workpiece W from the workpiece seating recess 3g without disturbing the glue sleeve block 3a while maintaining the molded product, so that the structure of the plastic packaging mold 1 can be simplified.

(Loader action)

Here, an example of the molding operation of the resin molding device will be described together with the loading and unloading operations of the workpiece to the molding die. First, with reference to FIGS. 1 to 5, the work carrying-in operation by the loader 4 will be described.

In Figure 1, the workpiece W (rectangular substrate) and the plastic resin R1 are loaded into the mold The lower mold 3. In the lower mold 3, the rubber inlet sleeve block 3a and the rubber inlet sleeve 3e are urged by the coil spring 3c, and are in a raised position compared to the lower mold clamping surface (the upper surface of the lower mold insert 3b), and the support pin 3i is at A state protruding from the workpiece placement recess 3g.

The loader 4 holds the molded resin R1 in the resin input portion 4b, and the pair of workpiece holding portions 4d hold the loading hand 4f at a position separated from each other (left and right opened position) from the resin input portion 4b by a sliding mechanism 4e, and is open The claws 4g grip both sides in the short-side direction of the workpiece W (rectangular substrate), and enter the plastic molding mold 1 in this state.

In FIG. 2, the loader 4 is lowered, and the workpiece W held by the loader hand 4f is placed on the plurality of support pins 3i protruding from the workpiece placement recess 3g. The opening and closing pawl 4g is in a state where the workpiece W is kept closed.

In FIG. 3, the slide mechanism 4e is operated, and the pair of loading hands 4f slides in the direction approaching the resin injection part 4b. At this time, the opening and closing claws 4g are located between the bridge portions 3d in a plan view, so they do not interfere with the glue sleeve block 3a, and the height of the upper surface of the workpiece W becomes a position lower than the lower surface of the bridge portion 3d Therefore, the tip of the workpiece W slides so as to sneak under the bridge portion 3d. Furthermore, since the resin input part 4b is located directly above the filling sleeve block 3a, the shutter 4c is opened, and the molding resin R1 (resin pellet) is injected into the filling sleeve 3e.

In FIG. 4, the opening and closing claws 4g of the loading handle 4f are opened, and the workpiece W (rectangular substrate) is delivered to the support pin 3i. At this time, the positioning hole Wh of the workpiece W is aligned with the positioning pin 3j of the lower mold 3. The opening and closing claws 4g are arranged in the avoidance space S (refer to FIG. 12B) of the glue sleeve block 3a in a plan view, and therefore do not interfere with the bridge portion 3d.

In Fig. 5, after the loader 4 delivers the workpiece W to the lower mold 3, the loader body 4a rises and retreats from the plastic mold 1. Furthermore, the loading of the workpiece W and the molding resin R1 into the molding mold 1 is completed, and thus the clamping operation of the molding mold 1 is performed. That is, since the lower mold 3 starts to rise, the support pins 3i are relatively lowered, the positioning pins 3j are fitted into the positioning holes Wh, and the workpiece W is positioned and placed in the workpiece placement recess 3g.

Furthermore, since air is sucked in advance from the suction hole 3h provided in the workpiece placement recess 3g, or air is sucked after the workpiece is placed, the workpiece W is positioned and fixed to the workpiece placement recess 3g.

In this way, in the opened plastic sealing mold 1, the workpiece W carried in by the loader 4 is positioned in the workpiece placement recess 3g of the lower mold 3. By clamping the mold, the rubber feeding sleeve block 3a is pressed down by the upper mold 2, and the rubber feeding sleeve The workpiece W is clamped between the cylinder block 3a and the lower mold insert 3b, so the structure of the mold side becomes simple, the mold cost becomes low, and the plastic resin R1 can be avoided to detour to the end surface of the workpiece, and it is not easy to cause malfunction in the mold. Moreover, maintenance can be carried out easily.

(Plastic mold action)

Next, the resin molding operation performed by the molding die 1 will be described with reference to FIGS. 7 to 11. FIG. 7 shows a state in which the workpiece W is set in the workpiece setting recess 3g of the lower mold 3, and the resin pellet R is loaded in the glue sleeve 3e. The rubber inlet sleeve block 3a and the rubber inlet sleeve 3e are urged by the coil spring 3c to be in a raised position. The clamping surface of the upper mold 2 sucks and holds the release film F, and the auxiliary pin 2d protrudes from the clamping surface of the upper mold so as to press the release film F downward.

When the mold clamping action is performed and the upper mold 2 touches the rubber inlet sleeve block 3a, the rubber inlet sleeve block 3a and the rubber inlet sleeve 3e are pressed down against the force of the coil spring 3c. Next, When the lower mold 3 and the upper mold 2 are closed as shown in FIG. At this time, the bridge portion 3d provided in the glue-in sleeve block 3a straddles the outer peripheral edge portion of the workpiece W positioned in the workpiece placement recess 3g, and presses the upper surface (substrate surface) of the workpiece. Thereby, between the upper mold residual material portion 2b, the upper mold runner gate 2c and the upper end surface (the upper surface of the bridge portion 3d) of the injection sleeve block 3a, there are formed at multiple locations (five locations in FIG. 12) A resin path communicating with the upper mold cavity recess 2a. And the auxiliary pin 2d (refer FIG. 7) protruding from the upper mold|type 2 touches the board|substrate surface of the workpiece|work W which opposes, and is pressed back.

In FIG. 9, a heater (not shown) is built in the plastic molding mold 1, and the plastic molding resin R1 melted in the injection sleeve 3e is raised by the extrusion head 3f, and then passes through the upper mold remnant part 2b and the upper mold flow The resin path between the pass gate 2c and the upper end surface of the injection sleeve block 3a is filled into the upper mold cavity recess 2a. The molding resin R1 filled in the cavity 2a of the upper mold is heated and hardened (cured).

In Fig. 10, the plastic packaging mold 1 is opened. At this time, the lower mold 3 is lowered while sucking and holding the workpiece W in the workpiece placement recess 3g, whereby the rubber feeding sleeve block 3a and the rubber feeding sleeve 3e that are urged by the coil spring 3c rise relatively. Thereby, the encapsulation part PK (resin sealing part) of the molded workpiece W (molded product) and the excess resin R2 (molded product residual flow path) formed on the injection sleeve block 3a are gated off. In addition, the auxiliary pin 2d protrudes from the upper mold 2 and presses the substrate surface of the workpiece W, whereby the packaging portion PK and the upper mold cavity concave portion 2a covered with the release film F are easily demolded.

Next, in FIG. 11, when the mold is opened, the support pin 3i protrudes from the workpiece placement recess 3g, and therefore the workpiece W is pushed up from the workpiece placement recess 3g. By this, work The piece W is in a state where the positioning pin 3j comes out of the positioning hole Wh. In addition, the air suction of the suction hole 3h provided in the workpiece placement recess 3g may be continued or may be stopped together with the mold opening.

(Uninstaller action)

Finally, with reference to FIGS. 13 to 16, the work unloading operation performed by the unloader 5 will be described. In FIG. 13, the unloader 5 enters the opened plastic mold 1. In the lower mold 3, the rubber inlet sleeve block 3a and the rubber inlet sleeve 3e are urged by the coil spring 3c to be in a raised position relative to the lower mold clamping surface (the upper surface of the lower mold insert 3b), and the support pin 3i is positioned from the workpiece The state where the recess 3g is protruding. Therefore, the molded workpiece W (molded product) and the excess resin R2 (molded product residual material flow path) are in a separated state. The unloader 5 holds the unloader hand 5f at a position (close to the center) where the pair of workpiece recovery parts 5d approach the remaining material holding block 5b through the sliding mechanism 5e, and the opening and closing claws 5g are opened, and in this state, it enters the plastic package Mold 1.

In FIG. 14, the unloader 5 descends, and the opening and closing claws 5g of the unloader hand 5f enter both sides of the workpiece W supported by the support pin 3i. At this time, the opening and closing claws 5g are located between the bridge portions 3d, so they will not interfere with the glue sleeve block 3a. In addition, the workpiece W is held by closing the opening and closing claws 5g. In addition, the remaining material holding block 5b presses the suction pad 5b1 against the excess resin R2 (molded product remaining material flow path), thereby adsorbing and holding the excess resin R2.

In Fig. 15, the sliding mechanism 5e is operated, and the pair of unloading hands 5f are respectively slid in a direction away from the remaining material holding block 5b (left and right sides).

In FIG. 16, the unloader body 5a of the unloader 5 rises from the state of holding the molded workpiece W (molded product) and excess resin R2 (molded product residual material flow path). Seal the mold 1 retreat.

The unloader 5 delivers the molded product to the molded product storage part, and collects the excess resin R2 to a scrap box, thereby ending a series of resin molding operations.

Regarding the resin molding device 6 including the molding mold 1, the loader 4, and the unloader 5, for example, it can be applied to the device shown in the plan layout diagram of FIG. 25.

In FIG. 25, the module-type resin molding device 6 is sandwiched between a workpiece and resin supply part 6a and a molded product and excess resin storage part 6b, and is formed by connecting a single or a plurality of pressurizing parts 6c. The loader 4 reciprocates between the workpiece and resin supply part 6a and the pressure part 6c, and the unloader 5 reciprocates between the pressure part 6c and the molded product and the accommodating part 6b of excess resin. Also, although not shown, the loader 4 and the unloader 5 can move back and forth along a moving rail that is provided for the workpiece and the resin supply part 6a, the pressure part 6c, the molded product, and the excess resin storage part 6b, or It can also move back and forth along individual moving tracks.

(Other embodiment 1)

Next, with reference to FIGS. 17 to 24, other embodiments of the plastic molding mold 1 will be described. The structure of the loader 4 and the unloader 5 are the same, so the same components are assigned the same numbers and the description is cited.

As shown in FIG. 17, in the lower mold 3, a plurality of support pins 3i protruding in the workpiece placement recess 3g are provided, but in order to simplify the mold structure, the plurality of support pins 3i may be omitted. The structure in which a suction hole 3h for sucking the workpiece W is provided in the workpiece placement recess 3g is the same.

As shown in FIG. 17, in the upper surface of the lower mold insert 3b, the workpiece|work mounting recessed part 3g (workpiece mounting part) in which the workpiece|work W is mounted is dug. The depth phase of the work placement recess 3g It is equivalent to the approximate degree of the plate thickness of the workpiece W.

FIG. 24 is a plan view of the lower mold 3. On the contour line L3 of the workpiece placement recess 3g, at a position that does not interfere with the bridge portion 3d provided in the glue sleeve block 3a, a pair of left and right opening and closing claws 4g are provided with escape recesses 3k at four places. The avoiding recessed portion 3k is a method that does not interfere with the opening and closing claws 4g of the loader 4 and the opening and closing claws 5g of the unloader 5 when the workpiece W is transferred between the lower mold 3 and the lower mold 3. A pair of left and right is provided correspondingly. Along the imaginary line L4 which is inside the outer line L3 of the workpiece placement recess 3g, a plurality of suction holes 3h for sucking and holding the workpiece W are arranged in a circumferential manner at equal intervals.

Hereinafter, the work carrying-in operation by the loader 4, the resin molding operation by the molding die 1, and the work unloading operation by the unloader 5 will be described centering on the differences. In addition, the description will be focused on the work-in operation of loading the work-in to the lower mold 3 by the loader 4, and the description of the work-out operation by the unloader 5 will be cited from the description of the loader 4.

(Loader action)

As shown in Fig. 17, first, the loader 4 holds the molded resin R1 in the resin input portion 4b, and holds the pair of workpiece holding portions 4d at a position separated from each other from the resin input portion 4b by a sliding mechanism 4e (left and right opened positions). The hand 4f is loaded, and both sides of the short side direction of the workpiece W (rectangular substrate) are held by the opening and closing pawls 4g, and the plastic mold 1 is entered in this state. In the lower mold 3, the rubber inlet sleeve block 3a and the rubber inlet sleeve 3e are urged by the coil spring 3c, and are in a raised position relative to the lower mold clamping surface (the upper surface of the lower mold insert 3b).

Next, the sliding mechanism 4e is operated, and the pair of loading hands 4f is slid in a direction approaching the resin input portion 4b. At this time, the opening and closing pawls 4g are located between the bridge portions 3d in a plan view, so they will not interfere with the glue sleeve block 3a. Furthermore, since the resin input part 4b is located directly above the filling sleeve block 3a, the shutter 4c is opened, and the molding resin R1 (resin pellet) is injected into the filling sleeve 3e.

In FIG. 19, the loading handle 4f is further lowered, the opening and closing pawl 4g is lowered to enter the avoiding recess 3k, the opening and closing pawl 4g is opened, and the workpiece W is delivered to the workpiece placement recess 3g. At this time, the positioning hole Wh of the workpiece W and the positioning pin 3j of the lower mold 3 are aligned and fitted. Furthermore, since the suction hole 3h previously provided in the workpiece placement recess 3g starts to suck air, the workpiece W is positioned and fixed to the workpiece placement recess 3g. The movement of the work W as a whole draws an L-shaped trajectory with an inverted L-shaped trajectory that is opposite to the left and right, and moves.

In FIG. 20, after the loader 4 delivers the workpiece W to the lower mold 3, the loader body 4a rises and moves and retracts from the plastic mold 1 in the X-Y direction. Furthermore, since the loading of the workpiece W and the molding resin R1 is completed, the clamping operation of the molding mold 1 is performed.

(Plastic mold action)

Next, the resin molding operation performed by the molding die 1 will be described with reference to FIGS. 21 to 23. FIG. 21 shows a state in which the workpiece W is set in the workpiece setting recess 3g of the lower mold 3, and the resin pellet R1 is loaded in the glue sleeve 3e. The rubber inlet sleeve block 3a and the rubber inlet sleeve 3e are urged by the coil spring 3c to be in a raised position. Moreover, the clamping surface of the upper mold 2 sucks and holds the release film F, and the auxiliary pin 2d is used to press the release film F down. The way protrudes from the upper mold clamping surface.

When the mold clamping operation is performed, as shown in FIG. 22, the rubber inlet sleeve block 3 a and the rubber inlet sleeve 3 e are clamped by the upper mold 2 and the lower mold 3. At this time, the bridge portion 3d provided in the glue-in sleeve block 3a straddles the outer peripheral edge portion of the workpiece W positioned in the workpiece placement recess 3g, and presses the upper surface (substrate surface) of the workpiece. Thereby, a plurality of places (five places in FIG. 24) are formed between the upper mold remnant part 2b, the upper mold runner gate 2c, and the upper end surface (the upper surface of the bridging part 3d) of the injection sleeve block 3a A resin path communicating with the upper mold cavity recess 2a. Then, the auxiliary pin 2d protruding from the upper mold 2 touches the substrate surface of the opposing workpiece W and is pressed back.

In Fig. 22, a heater (not shown) is built in the mold base and/or the plastic molding mold 1, and the plastic resin R1 melted in the feeding sleeve 3e passes through the upper mold remnant part through the ascending of the extruder 3f 2b. The resin path between the upper mold runner gate 2c and the upper end surface of the injection sleeve block 3a is filled into the upper mold cavity recess 2a. The molding resin R1 filled in the cavity 2a of the upper mold is heated and hardened (cured).

In Figure 23, the plastic packaging mold 1 is opened. At this time, the lower mold 3 is lowered while sucking and holding the workpiece W in the workpiece placement recess 3g, whereby the rubber feeding sleeve block 3a and the rubber feeding sleeve 3e that are urged by the coil spring 3c rise relatively. Thereby, the molded workpiece W (molded product) and the excess resin (molded product residual material flow path) formed on the injection sleeve block 3a are gate-cut. Furthermore, the auxiliary pin 2d protrudes from the upper mold 2 and presses the substrate surface of the workpiece W, whereby the package portion P and the upper mold cavity concave portion 2a are easily demolded.

(Uninstaller action)

The unloader 5 protects the remaining material in the pair of workpiece recovery parts 5d through the sliding mechanism 5e. The position where the holding blocks 5b are close to each other (the position near the center) holds the unloading hand 5f, and the opening and closing claws 5g are opened, and enter the plastic packaging mold 1 in this state.

As with the loader 4 shown in FIG. 19, the unloader 5 descends, and the opening and closing claws 5g of the unloader hand 5f enter the avoidance recess 3k on both sides of the workpiece W placed in the workpiece placement recess 3g. At this time, the opening and closing claws 5g are located between the bridging portions 3d in a plan view, so they will not interfere with the rubber feeding sleeve block 3a. In addition, the pair of opening and closing claws 5g enter the avoiding recess 3k, so that it does not interfere with the workpiece placement recess 3g. Next, the workpiece W is held by closing the opening and closing claws 5g. In addition, the remaining material holding block 5b presses the suction pad 5b1 against the excess resin R2 (molded product remaining material flow path), thereby adsorbing and holding the excess resin R2.

In FIG. 16, the sliding mechanism 5e is operated, and the pair of unloading hands 5f are respectively slid in the direction away from the remaining material holding block 5b (left and right sides).

In FIG. 16, the unloader body 5a of the unloader 5 rises while holding the molded workpiece W (molded product) and the excess resin R2 (molded product residual material flow path), and is retracted from the molding die 1.

At this time, it is possible to omit the multiple support pins 3i provided in the workpiece placement recess 3g of the lower mold 3 of the plastic packaging mold 1, so that the structure of the plastic packaging mold 1 can be further simplified, the device cost can be suppressed, and a high-quality resin plastic packaging can be realized. In the case of the above-mentioned embodiment, the workpiece W is slid laterally on the support pin 3i. However, in the other embodiment 1, the aspect of lateral sliding on the workpiece placement recess 3g or in the space directly above is different.

(Other embodiment 2)

The described embodiment and the other embodiment 1 are centered on the glue sleeve block 3a provided with a plurality of glue sleeves 3e, and are arranged in such a way that a pair of workpieces W are on both sides and the long sides face each other. However, it is not necessary for the workpieces W to be two pieces. Even if one workpiece W is placed on the workpiece mounting portion arranged on the side of the glue sleeve block 3a, the same can be implemented.

As described above, in this way, the loader body 4a is inserted into the opened plastic molding mold 1, and the resin injection portion 4b is used to inject the molding resin R1 into the injection sleeve 3e of the injection sleeve block 3a, and the workpiece W before molding is held The pair of workpiece holding portions 4d close to each other to a position where the glue sleeve block 3a in the raised position and the workpiece placement recess 3g overlap in a plan view, and the workpiece W is delivered to the mold clamping surface, thus the workpiece holding portion In 3d, the workpiece W can be positioned and carried into the workpiece placement recess 3g without interfering with the glue sleeve block 3d while maintaining the workpiece W. Moreover, the unloader body 5a can enter the opened plastic mold 3, the remaining material holding block 5b (excess resin recovery part) adsorbs and retains the excess resin R1 supported by the injection sleeve block 3a, and a pair of workpiece recovery parts 5d hold The formed workpieces W are kept away from each other to a position where they do not interfere with the rubber feeding sleeve block 3a, and the formed workpieces are carried out. Through the above, the structure of the plastic packaging mold 1 can be simplified.

In this way, for the opened plastic molding mold 1, the workpiece W is carried into the workpiece placement recess 3g by the loader 4, and positioned without interfering with the glue sleeve block 3a, and the unloader 5 is used to transfer the formed workpiece W and The excess resin R2 is taken out from the workpiece placement recess 3g without interfering with the rubber inlet sleeve block 3a, so the structure of the mold side becomes simple, the mold cost becomes low, and the plastic sealing resin R1 can be prevented from winding to the end surface of the workpiece, and it is not easy to cause the mold in the mold. The operation is poor, and maintenance can be easily performed.

For the resin molding device including the molding die 1, the cost of the device can be suppressed, and a resin molding device with high molding quality can be realized.

In addition, the molding resin R1 is not limited to resin pellets, and for example, pelletized resin, powdered resin, liquid resin, etc. may be supplied.

In the plastic molding mold 1, the upper mold 2 is formed with a cavity recess, but the lower mold 3 may be provided with a cavity recess.
