The plurality of lower movable pins 19 move in the up and down direction as the lower movable pin plate member 53 moves in the up and down direction. That is, the plurality of lower movable pins 19 move in the up and down direction as the camshaft 40 moves in the left and right direction in FIG. 4 .

Furthermore, in the above example, the left-right direction in FIG. 4 is the left-right direction of the resin sealing device 100, and the camshaft 40 moves in the left-right direction of the resin sealing device 100. However, it is not limited to this example. For example, the moving direction of the camshaft 40 may be a direction other than the left-right direction of the resin sealing device 100, such as the front-rear direction of the resin sealing device 100.

In the resin sealing device 100 , the lower driving plate member 51 moves in the up and down direction in accordance with the left and right movement of the pair of camshafts 40 . Therefore, in the resin sealing device 100, compared with the case where the lower driving plate member 51 is driven by one camshaft 40, the lower driving plate member 51 can be moved with high precision.

Furthermore, since the pair of camshafts 40 are disposed at a position sandwiching the lower driving plate member 51 between each other, the lower driving plate member 51 can be moved with higher accuracy. In addition, since the pair of camshafts 40 have the same shape, the lower driving plate member 51 can be moved with higher precision, and the manufacturing cost of the camshafts 40 can be reduced.

Furthermore, a plurality of upper movable pins 18 and lower movable pins 19 may be provided for one mold cavity 72 . Thereby, the resin sealing device 100 can fix the position of the molded product 90 with higher accuracy.

Here, the movement of the upper movable pin 18 and the lower movable pin 19 by each of the first moving mechanism 16 and the second moving mechanism 17 when the molded product 90 is resin sealed in the resin sealing device 100 will be described.

As shown in FIG. 9 , when the upper mold 10 and the lower mold 11 are closed, the front end of the upper movable pin 18 is in contact with the upper surface of the molded product 90 , and the front end of the upper movable pin 18 is in contact with the lower surface of the molded product 90 . Lower movable pin 19 front end. Thereby, as shown in FIG. 1 , the molded product 90 is supported by the upper movable pin 18 and the lower movable pin 19 , and the position of the molded product 90 is fixed in the mold cavity 72 .

Thereafter, the sealing resin 91 disposed in the pouring cavity 74 of the lower mold 11 is pressurized by the plunger 81. As shown in FIG. 1, the sealing resin 91 is fed to the mold cavity 72 through the reject part 70 and the runner part 71. within.

Then, after the sealing resin 91 is filled in the mold cavity 72 as shown in FIG. 10 , and before the sealing resin 91 is solidified as shown in FIG. 11 , the upper movable pin 18 and the lower movable pin 19 are moved by the first moving mechanism 16 ( 4) and the second moving mechanism 17 (see FIG. 4).

In the above example, the example in which the first moving body 30 moves in the left-right direction or the front-rear direction of the resin sealing device 100 has been described, but it is not limited to this example. The first movable body 30 is not limited to the above example as long as it can move in a direction intersecting with the direction in which the upper mold 10 and the lower mold 11 are clamped, that is, the mold closing direction.

In the resin sealing device 100 having the structure shown in FIG. 3 , since the transfer unit 7 is disposed below the movable platen 3 , the length in the vertical direction becomes longer, and the first moving body 30 of the second moving mechanism 17 is in contact with the vertical direction. Move in the direction of cross direction. Therefore, the resin sealing device 100 can be prevented from increasing in size in the vertical direction.

In the above example, the first moving mechanism 16 and the second moving mechanism 17 have different structures.

Furthermore, in the above example, the case where the lower movable pin 19 is a pull-out pin has been explained, but the lower movable pin 19 is not limited to a pull-out pin. For example, the lower movable pin 19 may be an exhaust port pin as shown in FIG. 13 . The exhaust port pin is a pin that enters and exits the exhaust port 73 having a flow path for releasing the air in the mold cavity 72 to the outside, and switches the opening and closing state of the exhaust port 73 .

The exhaust port 73 is open until the sealing resin 91 is filled in the mold cavity 72. After the sealing resin 91 is filled in the mold cavity 72, as shown in FIG. 13, the lower movable pin 19 penetrates into the exhaust port 73. flow path, and the exhaust port 73 becomes closed.

In addition, the moving mechanism of the resin sealing device 100 that moves the extraction pin in the up-and-down direction and the moving mechanism that moves the exhaust port pin in the up-and-down direction can be configured similarly to the second moving mechanism 17 . This further suppresses the resin sealing device 100 from being enlarged in the mold closing direction.

In addition, the second moving mechanism 17 is provided with the camshaft 40 including the cam groove 40a for pulling the pin and the cam groove 40a for the exhaust port pin, so that it can be used for both pulling the pin and the exhaust port pin.

For example, in the resin sealing device 100, the second moving mechanism 17 may be configured such that a cam slider is provided on the camshaft 40 instead of the cam groove 40a, and a cam driver may be configured to drive the plate member 51 from below instead of the cam follower 50. The side surface 51a protrudes.

As described above, the resin sealing device 100 of the embodiment includes the first movable body 30 , the second movable body 31 , and the lower movable pin 19 . The lower movable pin 19 is an example of the movable pin.

The above-mentioned up and down direction is an example of the mold clamping direction, and the above-mentioned left and right direction is an example of the first direction. Along with the movement of the first movable body 30 in the first direction, the second moving body 31 moves in the mold closing direction and in the second direction approaching one of the upper mold 10 and the lower mold 11 . The above-mentioned up-down direction is an example of the second direction. The lower movable pin 19 is attached to the second moving body 31 . As the second moving body 31 moves in the second direction, it moves in the second direction. Thereby, in the resin sealing device 100, compared with the case where the first moving body 30 is configured to move in the mold closing direction, it is possible to suppress an increase in size in the mold closing direction.

Moreover, the camshaft 40 faces the side surface 51a of the lower driving plate member 51 on which the cam follower 50 is mounted, and moves along the side surface 51a. Thereby, in the resin sealing device 100, the lower driving plate member 51 and the camshaft 40 can be arranged at the same position in the vertical direction, so that the resin sealing device 100 can be suppressed from being enlarged in the mold closing direction.

Furthermore, the first moving body 30 includes a pair of camshafts 40 . The pair of camshafts 40 are arranged at a position where the lower driving plate member 51 is sandwiched between each other.
