The cylindrical portion 131a extends to the inside of the first support body 131 to form a through hole. The guide shaft 133 is inserted into the cylindrical portion 131a. Therefore, the cylindrical portion 131a extends along the guide shaft 133. Further, the first support 131 has a screw hole 131b for fixing the fixed molding die 52 from the outer side in the width direction. The movable molding die 50 is sandwiched between the fixed molding die 52 and the first support 131 so as to be vertically movable.

On the inner side surface of the block portion 139b, a concave portion 139ba that is recessed outward is formed. The movable blade 115b slides in the vertical direction in the recess 139ba. Therefore, the inner surface of the recess 139ba becomes the sliding surface of the movable blade 115b.

  The second support 139 has a through hole 139c into which the cylindrical portion 131a of the first support 131 is inserted and a through hole 139d into which the screw shaft 135 is inserted. The second support 139 is placed on the cylindrical portion 131 a of the first support 131 by inserting the cylindrical portion 131 a of the first support into the through hole 139 c of the second support 139. Accordingly, the second support 139 can also move in the width direction along with the movement of the first support 131 in the width direction along the guide shaft 133.

  The second support 139 has a protrusion 139g that protrudes forward and backward. The projecting portion 139g is formed with a screw hole 139h (see FIG. 14) downward from the upper surface.

The ring 135k has an opening surface 135n that contacts the tongue piece 135h, a groove 135p that reaches the opening surface 135n from the outer peripheral surface, and a screw hole 135q formed so as to face each other with the groove 135p interposed therebetween. By tightening the bolts 135m into the two screw holes 135q of the ring 135k, the tongue pieces 135h and the tip portion of the right screw shaft 135c are tightened and fixed.

  The pitch of each of the right thread 135a and the left thread 135b is the same. Therefore, in accordance with the rotation of the right screw shaft 135c, the right first support 131R and the left first support 131L screwed into the respective threads move the same distance in the direction toward or away from each other. . Each of the pair of first supports 131 screwed into the screw shaft 135 is displaced by the same displacement amount with respect to the central portion of the screw shaft 135 by the movement of the screw shaft 135. Accordingly, the user can perform the initial adjustment, and the pitch adjustment of the molding die 49 can be performed only by rotating the screw shaft 135. In this initial adjustment, the right-hand screw shaft 135c and the collar 135d can be separated and the right-hand screw shaft 135c and the collar 135d can be integrated by the ring 135k after the adjustment. Accordingly, the position adjustment of the right screw shaft 135c and the right first support 131R and the position adjustment of the collar 135d and the left first support 131L can be independently performed, so that the initial adjustment can be facilitated.

  Further, when adjusting the molding pitch Fp, the user can adjust the distance between the pair of first support members 131 simply by rotating the head 135g of the right-hand screw shaft 135c.

  Next, the structure of the second support 139 will be described with reference to FIG. FIG. 12 is a perspective view of the second support 139. The second support 139 is detachably fixed to the main body 139a from above by the screw 147. The fixed blade 115a is fixed to the block portion 139b, and in particular, is fixed to the inner surface in the width direction (X direction) of the block portion 139b with, for example, a screw 140.

  Next, with reference to FIG. 13, the fixing of the first support 131 to the support member 141 will be described. FIG. 13 is a cross-sectional view of the first support 131 taken along the line XIII of FIG. By fixing the first support 131 to the support member 141, which is a plate member different from the guide shaft 133, it is difficult to move the first support 131 in the direction along the guide shaft 133 due to the deformation of the fixing portion 142. Can be prevented. The support member 141 may be a column member instead of the plate member.

  The fixing portion 142 is, for example, a bolt 145 that is tightened in a screw hole 131 d formed in the first support 131, a part of the fixing part 142 is sandwiched between the support member 141 and the bolt 145, and a part of the fixing part 142 is the first support 131 and the bolt 145. And a spacer 143 sandwiched between.

The lower surface of the supporting member 141 contacts the upper surface of the protruding portion 131c, and is fixed to the upper surface of the supporting member 141 and the upper surface of the protruding portion 131c with a bolt 145 via a spacer 143.

  Next, referring to FIG. 14, access to the fixed mold 52 will be described. FIG. 14 is a partially exploded perspective view of the molding pitch adjusting mechanism 130.

  The second support 139 extends in the width direction (X direction) of the screw hole 131b (see FIG. 8) of the fixed mold 52 of the first support 131 in a state of being inserted into the cylindrical portion 131a of the first support 131. It has a through hole 139e and a groove 139f formed above. Thus, from the outside of the second support 139, through the second support 139, to access the screw hole 131b of the fixed mold 52 of the first support 131 and the screw 55 fastened to the screw hole 131b. Therefore, the fixed mold 52 can be attached and detached without removing the second support 139. The fastening portion that fastens the fixed molding die 52 to the first support 131 is constituted by, for example, the screw hole 131 b of the fixed molding die 52 and the screw 55.

  Further, for example, three screws 55 for fixing the fixed mold 52 to the first support 131 can be accessed from the outside of the frame 137 by, for example, a hexagon wrench 57. More specifically, the hexagon wrench 57 passes through the through hole 137a or the groove 137b of the frame 137, the through hole 139e or the groove 139f of the main body 139a of the second support 139, and the block portion of the second support 139. The screw 55 is accessible through the through hole 139bb of the 139b and the through hole 139e of the fixed blade 115a. Accordingly, the fixed mold 52 can be attached and detached without removing the first support 131 and the second support 139 from the guide shaft 133.

The upper end of the elevating rod 251 is connected to the chuck driving motor 241 via a speed reducing mechanism including a worm wheel 241a and a worm gear 241b. When the chuck driving motor 241 rotates the worm gear 241b, the worm wheel 241a that meshes with the worm gear 241b swings. As a result, the lifting rod 251 connected to the worm wheel 241a moves in the Z direction, that is, moves up and down.

  The chuck unit 25 has a pair of claw portions 39 (39a, 39b) for holding the component 3. The claw portion 39 chucks (holds) the component 3 and is made of a metal that is resistant to wear. The claw portion 39a and the claw portion 39b are connected to a lifting rod 51 of the head lifting mechanism 26 via a slide mechanism 38, respectively. The slide mechanism 38 is operated by the elevation of the elevating rod 251, and the claw portions 39a and 39b approach or separate from each other. That is, the distance between the claws 39a and 39b can be adjusted. In this way, the chuck unit 25 functions as a space adjusting unit that adjusts the space between the claws 39a and 39b (the space between the pair of claws 39).

  When the elevating rod 251 is located at the uppermost position, the claw portion 39a and the claw portion 39b are most separated from each other. When the elevating rod 251 descends, the claw portions 39a and 39b move so as to approach each other by the slide mechanism 38 accordingly. When the elevating rod 251 descends to the lowest position, the claw portions 39a and 39b contact each other.
