Embodiment Construction

[0045] Embodiments of the present invention will be described below based on the drawings.

[0046] 【Example】

[0047] Such as figure 1 As shown, the injection molding machine base (hereinafter, simply referred to as the base.) 30 includes a mold opening and closing actuator ( figure 2 , 2 side frames 40 extending parallel to the axis of symbol 16); the front beam 31 connecting the front ends of the two side frames 40; the rear beam 32 connecting the rear ends of the two side frames 40; the front beam 31 Bolts 33 fixed to the two left and right side frames 40 ; and Bolts 34 fixed to the two left and right side frames 40 of the rear beam 32 .

[0048] Since they are fixed by the bolts 33 and 34, the two side frames 40, the front cross member 31, and the rear cross member 32 can be separately manufactured. The two side frames 40 , the front cross member 31 , and the rear cross member 32 that are manufactured separately are transported to the installation site. The two side...

Abstract

Provided is a base used in an injection molding machine achieving mutual fixation of components through welding merely even being provided with a plurality of webs. As shown in FIG (a), the webs (46)are arranged vertically on the lower flange and the web (46) and the lower flange (44) are secured by a weld pass (B1). Since the electrode (56) can be inserted from the outside, the welding operationis easy. Then a web reinforcement (47) is inserted into a frame hole (46a) in the web 46. As shown in Fig. (b), an end portion of the web reinforcement (47) projects from the web (46). A welding rod(56) is inserted from the outside and the web reinforcement (47) is welded to the web (46). The web reinforcement (47) is secured to the web (46) by means of a weld pass (B2). An upper flange (45) isuploaded and placed on the web (46). Although two webs are arranged, mutual fixation of components through welding merely.

Description

technical field [0001] The invention relates to bases for injection molding machines. Background technique [0002] The clamping device of the injection molding machine has: a base fixed on the machine base or a base; a fixed plate fixed on the base; a pressure plate (or a mold clamping cylinder) arranged parallel to the fixed plate on the base ); a connecting rod arranged between the fixed plate and the pressure receiving plate; and a movable plate arranged between the fixed plate and the pressure receiving plate and moving on the base while being guided by the connecting rod. [0003] The mold is clamped by the movable plate and the fixed plate. [0004] The base used for the mold clamping device is required to be rigid enough to withstand the reaction force of the mold clamping. Therefore, various base structures have been proposed (for example, refer to Patent Document 1). [0005] based on Figure 9 and Figure 10 The base structure shown in Patent Document 1 will b...
