[0035] [Structure of forming device]

[0036] like figure 1 As shown, the forming device 1 includes the following parts: an upper mold 10 ("the first mold" in the claims) and a lower mold 20 ("the second mold" in the claims), which are configured to form a mold when the molds are closed. cavity (not shown), and the lens is formed in the cavity; the mold body 30, which is fitted from the outside by straddling the upper mold 10 and the lower mold 20, thereby forming the upper mold 10 and the lower mold 20 for center alignment; and a base member 40 mounted with a slider 44 for moving the upper die 10 and a support member 50 for supporting the lower die 20 .

[0037] Moreover, this molding device 1 is a device for performing a process of putting materials into and assembling between the upper mold 10 and the lower mold 20, and the upper mold 10 and the lower mold 20 assembled by the molding device 1 are held together by the supporting member 50. Transfer to other forming device...

no. 2 approach

[0069] In the forming apparatus of the second embodiment, as shown in FIG. 4 , the supporting member 60 attached to the slider 44 is configured to support the upper mold 10 ("second mold" in the claims) in a floating state and Fixed state. Specifically, the upper mold 10 is held by the chuck member 45' ("holding member" in the claims), and the upper mold 10 is supported by the support member 60 via the chuck member 45'.

[0070] In addition, the lower mold 20 ("first mold" in the claims) is fixed to the upper surface of the base plate 41 of the base member.

[0071] As shown in FIG. 4( a), the supporting member 60 of the second embodiment is a hollow box having an internal space 61, and a circular through hole 61a is formed on its lower plate, through which the chuck member 45 passes. ' is arranged in the internal space 61. In addition, a disk-shaped flange portion 45a having a larger diameter than the through-hole 61a is formed on the upper end portion of the chuck member 4...

Abstract

A molding device includes an upper mold 10 (first mold), a lower mold 20 (second mold) and a body mold 30 that aligns axes of the upper and lower molds 10, 20 with each other by being fitted to an exterior of the upper mold 10 and an exterior of the lower mold 20 with the body mold 30 straddling the upper and lower molds 10, 20. The lower mold 20 is supported by a support member 50. The support member 50 can support the lower mold 20 with the lower member 20 being in a floating state.

Description

technical field [0001] The present invention relates to a molding device for assembling two molds, and a method of assembling a mold using the molding device. Background technique [0002] As a molding device for manufacturing optical parts such as glass lenses, for example, such as Figure 5 As shown, there is a forming device 100, which closes an upper mold 110 having a cavity surface 111 on the lower end surface and a lower mold 120 having a cavity surface 121 on the upper end surface to form a cavity (not shown), The material is pressed in this cavity to form products such as lenses. [0003] In the conventional molding apparatus 100 described above, when assembling the upper mold 110 and the lower mold 120, first, a cylindrical mold body is inserted from the outside into the lower mold 120 fixedly mounted on the base plate 141 of the base member. 130, afterward, by inserting the upper mold 110 supported by the slider (slider) 144 into the upper part of the mold body ...
