本考案はゴム加硫用プレスに於ける金型の支持
装置に関するものである。[Detailed Description of the Invention] The present invention relates to a support device for a mold in a press for rubber vulcanization.

不良となることがしばしばある。 In a system in which the mold of a rubber vulcanization press opens and closes using a hinge as a fulcrum, the raw material is inserted into the cavity of the lower mold, and the upper mold is closed on top of the lower mold to press and heat it. and molded. However, the raw material inserted into the cavity of the lower mold is generally in the form of a lump and protrudes upward from the surface of the lower mold. When the upper mold opened via the hinge is stacked on the lower mold, that is, when the upper mold is closed, the raw material protruding from the cavity is pushed laterally on the hinge side of the mold by the circular arc movement of the upper mold. This causes it to protrude beyond the cavity. For this reason, molded products often become defective.
本考案はこれに鑑みてヒンジ式開閉金型に於て
も下金型キヤビテイ内の原料が常に上金型により
垂直に押圧され確実にキヤビテイ内に充填され成

る。 In view of this, the present invention was developed with the aim of ensuring that even in hinged opening/closing molds, the raw material in the lower mold cavity is always pressed vertically by the upper mold to ensure that it is filled into the cavity, thereby eliminating molding defects. It is something.
以下本考案を図示の実施例に基づいて説明す
る。 The present invention will be explained below based on the illustrated embodiments.

うになす。 In the figure, 1 is a press, 2 is a slide plate for attaching a lower mold, which is provided on this press so that it can move up and down and slide freely, and 3 faces upward from this slide plate 3, and can be opened and closed by a hinge. With a dripping top plate,
A lower mold 4 is fixed to the top surface of this slide plate 2, and an upper mold 5 is fixed to the lower surface of the upper plate.
The hinge on the top plate allows the upper and lower molds to be opened and closed.

少し隙間があくようにする。 The hinge between the upper plate and the slide plate is shown in detail in FIGS. 2 and 3. That is, bearings 6, 6 are vertically installed on the lower surface of one end of the upper plate, and one shaft 7 is passed through and horizontally spanned between the two opposing bearings 6, 6, and two shafts 7 are provided protruding from the upper surface of one end of the slide plate. The shaft 7 is supported by two bearings 8, 8, and the bearing 8 has a shaft hole 8a into which the shaft 7 is inserted, as shown in FIG. When the upper and lower molds are in contact with each other, the lower surface of the shaft 7 is supported by the inner bottom of the shaft hole 8a, or a slight gap is left.

うになす。 Further, a horizontal support device 9 for the upper mold is provided below the shaft 7 and close to the bearing 8 or 6. This is a recess 3a on the slide plate surface at the lower position of the shaft 7.
A spring 9a is fitted into this recess, and a spring receiver 9b is also fitted into this recess, and the elasticity of the spring 9a constantly applies a force to the spring receiver 9b in the direction of protruding upward. The spring receiver 9 is designed to prevent protrusion.
b is fitted with a bearing pin 9c, and this bearing pin 9c has a U shape on its top surface so as to support the lower surface of the shaft 7.
A letter-shaped groove 9d is provided. And this bearing pin 9c
The support of the shaft 7 is made such that a gap is created between the upper surface of the lower mold and the upper mold only at the height at which the raw material inserted into the cavity of the lower mold protrudes from the cavity, that is, a gap is created above the lower mold. to support the upper mold.

て行うものである。 Further, an upper mold support device 10 is provided on the slide plate surface on the opposite side to the upper mold horizontal support device 9. As with the horizontal support device 9, a spring 10b and a spring receiver 10c are fitted into a recess 10a formed on the slide plate surface, and the spring applies a force that causes the spring receiver 10c to protrude upward, but in such a way that the spring receiver 10c does not protrude. Along with the eggplant, this spring receiver 10
A pin 10d for supporting the upper plate is fitted into the upper plate c, and a part of the lower surface of the upper plate is supported by the upper end surface of this pin 10d. This pin 10d and the bearing pin 9c support the upper plate horizontally with a desired gap between the lower mold and the upper mold. This adjustment is performed by replacing the washer-like adjusting fitting.

できるものである。 Therefore, when using the present invention, even in a hinge type open/close mold, the upper mold is supported horizontally above the lower mold at the height of the raw material protruding from the cavity of the lower mold, and then both upper and lower sides are supported. Since the molds are pressurized so that they are in close contact with each other, the raw material is reliably filled even in the cavity near the hinge, which has the advantage of preventing defective molded products. It can also be easily applied to existing presses.
