Embodiment 1

[0024] figure 1 It is a schematic front view showing the configuration of the main part of the injection molding machine 100 according to the embodiment of the present invention, figure 2 From figure 1 A schematic side view of the injection molding machine 100 viewed in the direction indicated by arrow II of . in addition, image 3 and Figure 4 From figure 2 A schematic top view of the injection molding machine 100 viewed in the direction indicated by arrow III of .

[0025] The injection molding machine 100 mainly includes: a fixed platen 10, a movable platen 11, a toggle support 12, connecting rods 13a-13c, a servo motor 17 for mold clamping, a turntable 18, slide plates 19a, 19b, a toggle mechanism 20, and a deceleration mechanism 30 and injection device 40 .

[0026] The fixed platen 10 is a member for supporting the lower molds 16a and 16b via the turntable 18, is fixedly attached to a frame body not shown, and has three connecting rods 13a to 13c slidably penetr...

Embodiment 2

[0053] Next, refer to Figure 7 and Figure 8 Another example 10X of the fixed platen that can be attached to the vertical injection molding machine 100 according to the embodiment of the present invention will be described. in addition, Figure 7 It is a schematic plan view of the vertical injection molding machine 100 provided with the fixed platen 10X, which is the same as the image 3 correspond. in addition, Figure 8 is a schematic bottom view of the fixed platen 10X, with Image 6 correspond. Therefore, for the same or corresponding constituent elements, use the Figure 1~Figure 6 Refer to the same reference numerals as those used in .

[0054] Recesses 10Xa and 10Xb for accommodating slide plates 19Xa and 19Xb are formed on the upper surface 10t of the fixed platen 10X.

[0055] The slide plates 19Xa and 19Xb each include three plate-like members having arcuate surfaces. Furthermore, in the present embodiment, the center of the circular arc coincides with the ...

Embodiment 3

[0063] Next, refer to Figure 9 and Figure 10 Another example 10Y of the fixed platen that can be attached to the vertical injection molding machine 100 according to the embodiment of the present invention will be described. in addition, Figure 9 is a schematic plan view of the vertical injection molding machine 100 provided with the fixed platen 10Y, and image 3 correspond. and, Figure 10 is a schematic bottom view of the fixed platen 10Y, with Image 6 correspond. Therefore, for the same or corresponding constituent elements, use the Figure 1~Figure 6 Refer to the same reference numerals as those used in .

[0064] Recesses 10Ya and 10Yb for accommodating the sliding plates 19Ya and 19Yb are formed on the upper surface 10t of the fixed platen 10Y. In addition, each of the sliding plates 19Ya and 19Yb has a substantially triangular prism shape.

[0065] Thereby, the recessed parts 10Ya and 10Yb of the fixed pressure plate 10Y are respectively formed as recesses ...

Abstract

The present invention provides an injection moulding machine which can reduce the overall height or length of the injection moulding machine at the same time of maintaining the smooth rotation of a turntable. The injection molding machine (100) is provided with a fixed pressure plate (10), a turntable (18), and skateboards (19a,19b) arranged between the fixed pressure plate (10) and the turntable (18). One part of the main body of the skateboards (19a,19b) is buried in the upper surface (10t) of for the fixed plate (10) which faces against the turntable (18), and protrudes from the upper surface (10t).

Description

technical field [0001] The present invention relates to an injection molding machine provided with a turntable on which a plurality of molds are mounted around a rotating shaft. Background technique [0002] Conventionally, an injection molding machine including a turntable is known (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2008-80561 [0004] In the injection molding machine of Patent Document 1, the slide plate is fixed to the flat upper surface of the fixed die plate so that the upper surface of the slide plate for reducing frictional resistance is brought into contact with the lower surface of the turntable. With this configuration, the turntable of the injection molding machine of Patent Document 1 can be smoothly rotated. In addition, the slide plate is required to have high rigidity to withstand a large load at the time of mold clamping, and also requires processing for fixing to a fixed mold plate, so it mu...
