Definitions

  • the molding method according to claim 19 is provided with a first mold and a second mold, which are each provided with a lens transfer surface, and are relatively movable, and the first mold and the second mold.
  • a convex surface provided with an engagement plane and the other mold among the first mold and the second mold, and provided with an engagement plane.
  • FIG. 11 is a perspective view showing a block piece according to a modification of the present embodiment.
  • the block piece 125 has a substantially quadrangular prism shape in which the surfaces are orthogonal to each other, and includes a high upper surface 125a, a lower upper surface 125b that is parallel to the upper surface 125a and provided at a lower position, and a higher upper surface 125a. And an inclined slope 125c connecting the lower upper face 125b.
  • the high upper surface 125a is orthogonal to the long side surface 125d
  • the low upper surface 125b is orthogonal to the short side surface 125e parallel to the long side surface 125d.
  • the convex block 15 is formed.
  • the concave block 25 is formed.
  • a highly accurate block piece 125 having the same shape can be easily produced.
  • the slope 15a of the convex block 15 and the slope 25a of the concave block 25 are in contact with each other, thereby increasing the rigidity of the fitting portion and improving the positioning accuracy.
  • the load on the fitting portion can be reduced, there is an effect in extending the life of the fitting member.
  • a convex block 25A is provided in each rectangular hole 24aA.
  • the convex block 25A is formed of two parts (a block piece to be described later), and each has a height adjusting spacer 27A interposed by a bolt 26A inserted from the back side of the receiving plate 23A. While being screwed into the screw hole, it is fixed. However, both parts may be fixed to each other and one may be fixed with a single bolt.
  • the thermal expansion coefficient of the convex block 25A forming the convex part is larger than the thermal expansion coefficient of the movable side template 24A.
  • the shiftable direction may be rough positioning, there is an advantage that adjustment is easy. Furthermore, since there is an adjusting mechanism, the processing accuracy of the rectangular holes 12aA and 24aA formed in the fixed side mold plate 12A and the movable side template 24A does not need to be high. Therefore, processing accuracy and assembly time can be reduced.
  • this block piece 125A is combined to form the convex block 25A and the concave block 13A, even if the inclination angle of the inclined surface 125cA with respect to the high upper surface 125aA is slightly deviated from the target angle (for example, 45 degrees), As long as there is no difference in the inclination angle of the inclined surface 125cA between the block pieces 125A, the inclined angle of the inclined surface 125cA is uniform even in the combined state, and the inclined surface of the convex block 25A and the inclined surface of the concave block 13A are in uniform contact. Therefore, highly accurate positioning can be performed without causing unnecessary competition.
  • a sprue 12dA, a central recess 24dA, runner paths 12cA, 14cA are supplied from a supply source (not shown). Then, after filling the resin formed in the cavity formed by the transfer surfaces 12bA and 24bA and solidifying it, as shown in FIG. 15, the movable mold 20A is separated from the fixed mold 10A.
  • a circular nesting C3A surrounding the entire transfer surface 24bA may be provided in the circular opening 24gA of the movable side template 24A.
  • a circular nesting C4A that surrounds the entire transfer surface (not shown) facing the transfer surface 24bA may be provided in the opening 12gA of the stationary-side template 12A.
  • the circular inserts C3A and C4A are not directly inserted into the circular openings of the molds 10′A and 20′A, for example, FIG. 1, FIG. 2, FIG. A circular nesting may be inserted into the circular opening through a member described as reference numerals 34 and 35 in FIG. In this case, the number of balls of the rolling bearing is preferably about 50 to 200.

Abstract

La présente invention concerne un dispositif de moulage qui aligne un moule à côté fixe (10) et un moule à côté amovible (20) par mise en contact de blocs dotés de parties saillantes (15) et de blocs dotés de parties évidées (25). Ainsi, ledit dispositif permet d'obtenir une précision parfaite pour répéter un tel alignement et est capable de réduire efficacement toute excentricité entre les surfaces de formation de lentilles de contact des deux moules (10, 20). De plus, puisqu'il est possible de changer la position de la mise en contact de telle sorte que les blocs dotés de parties saillantes (15) et les blocs dotés de parties évidées (25) se croisent selon les bons angles suivant la direction de la fermeture, par alignement de la direction dans laquelle les moules (10, 20) se dilatent thermiquement et de la direction dans laquelle toute modification est permise, on peut alors réduire au minimum les erreurs d'alignement dues à tout écart de température survenant dans les moules (10, 20), en d'autres termes minimiser les erreurs d'alignement dues aux écarts observés entre les dilatations thermiques sans disposer de charge sur les moules.
