no. 1 Embodiment approach

[0020] figure 1 It is a figure which shows the state when the mold opening of the injection molding machine of the 1st Embodiment of this invention is completed. figure 2 It is a figure which shows the state when the mold closing of the injection molding machine of the 1st Embodiment of this invention is complete|finished. image 3 It is a figure which shows the state when the mold clamping of the injection molding machine of 1st Embodiment of this invention is complete|finished. Figure 4 It is a figure which shows the state at the time of the mold exchange of the injection molding machine of the 1st Embodiment of this invention.

[0021] The injection molding machine 10 includes a frame 11, a fixed platen 12, a movable platen 13, a short link 21, a long link 22, a push rod 23, a mold clamping motor 31, a mold thickness adjustment section 40, and a first link locking mechanism 60 And the pressure plate locking mechanism 70.

[0022] The fixed pressing plate 12 is fixed to the fram...

no. 2 Embodiment approach

[0057] In the first embodiment described above, the support guide 46 supports the movable pressure plate 13 from below, but the difference in this embodiment is that the support guide supports the movable pressure plate from the side. Hereinafter, the difference will be mainly explained.

[0058] Figure 5 It is a figure which shows the mold thickness adjustment part and movable platen of the 2nd Embodiment of this invention.

[0059] The mold thickness adjustment section 140 is formed by, for example, a main body 141, a support block 142 as a support for supporting the main body 141, an adjustment rod 143 that connects the main body 141 and the movable platen 113 at intervals in the mold opening and closing direction, and The adjustment nut 145 screwed to the screw shaft portion 144 of the adjustment rod 143 and an adjustment motor that rotates the adjustment nut 145 are configured.

[0060] The main body 141 is arranged behind the movable platen 113. The main body portion 141 has...

no. 3 Embodiment approach

[0071] In the first embodiment described above, the support guide 46 that movably supports the movable platen 13 in the mold opening and closing direction is provided on the support block 42. The difference in this embodiment is that the support guide is provided on the frame on. Hereinafter, the difference will be mainly explained.

[0072] Image 6 It is a figure which shows the mold thickness adjustment part and the movable platen of the 3rd Embodiment of this invention.

[0073] The mold thickness adjusting portion 240 is composed of, for example, a main body portion 241, a support block 242 that supports the main body portion 241, an adjustment rod 243 that connects the main body portion 241 and the movable platen 213 at intervals in the mold opening and closing direction, and is formed in The adjustment nut 245 to which the screw shaft portion 244 of the adjustment rod 243 is screwed and an adjustment motor that rotates the adjustment nut 245 are configured.

Abstract

The invention provides an injection molding machine capable of improving the balance of mold clamping forces. The injection molding machine 10 comprises a platen 13 to which a mold 15 is mounted, anda mold thickness adjustment part 40 which adjusts a mold thickness. The mold thickness adjustment part 40 includes a body part 41 which is connected to the platen 13 with a distance in a mold opening / closing direction, and a support part 42 which supports the body part 41. The support part 42 is longer than the body part 41 in the mold opening / closing direction.

Description

[0001] This application is a divisional application of the application with the filing date of "February 21, 2014", the application number of "201410059228.8", and the invention name of "injection molding machine". Technical field [0002] This application claims priority based on Japanese Patent Application No. 2013-090490 filed on April 23, 2013. The entire content of its application is used in this specification by reference. [0003] The invention relates to an injection molding machine. Background technique [0004] The injection molding machine fills the cavity of the mold device with molten resin and solidifies it to produce a molded product. The mold device is composed of a fixed mold and a movable mold, and a cavity space is formed between the fixed mold and the movable mold during mold clamping (for example, refer to Patent Document 1). [0005] Patent Document 1: Japanese Patent Application Publication No. 2006-305945 [0006] There is room for improvement in the balance o...
