Problems solved by technology

[0003] The existing brake mechanism of two-plate plastic injection molding machine adopts four sets of relatively independent hydraulically driven brake mechanisms. Since each brake mechanism receives different frictional resistance during movement, the synchronization of these four brake mechanisms whe

Example Embodiment

[0023] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0024] Such as figure 1 , 2 As shown in, 3 and 8, a two-platen injection molding machine generally consists of a fixed template 1, a movable template 3, and a tailstock 4, which are connected by a tie rod 2 to form the frame of the entire injection molding machine.

[0025] Such as Figure 5 , Image 6 As shown, the drive cylinder rear cover 18, the drive cylinder barrel 19, the drive cylinder front cover 20, and the drive cylinder piston rod 21 constitute a brake drive cylinder.

[0026] The piston rod 21 of the driving cylinder is connected to the brake nut-R 6 through the connecting shaft 23, and the rear cover 18 of the driving cylinder at the other end is connected to the brake nut-R 9 through the connecting pin 17 and the connecting block 16, wherein the brake nut-L 5 The two connecting rods 7 arranged diagonally are fixedly connected to the brake nut-R ...

Abstract

The invention discloses a two-trigger type injection molding machine brake mechanism, comprising four brake nuts and a drive cylinder, wherein the four brake nuts are divided into an upper group and a lower group in the same structure; each group of the brake nuts are divided into a left brake nut and a right brake nut; one end of the drive cylinder is fixed on the right-half brake nut of the left brake nuts; the piston rod of the drive oil cylinder is connected with the left-half brake nut of the right brake nuts; the left-half brake nut of the right brake nuts is connected with the right-half brake nut of the left brake nuts through a connection rod; and the right-half brake nut of the left brake nuts is connected with the left-half brake nut of each right brake nuts through a connection rod and a synchronous connection mechanism. The brake mechanism has the advantages of ensuring the synchronism of the operation of the brake mechanism and shortening the operation cycle of the brake mechanism, thereby saving the cost of the overall brake mechanism.

Description

technical field [0001] The invention relates to a mechanism of a two-platen injection molding machine, in particular to its brake mechanism. Background technique [0002] Since the clamping mechanism of the two-plate plastic injection molding machine does not have a toggle linkage device, the movement pairs of the mechanism are greatly reduced. Due to the reduction of mechanical vulnerable parts, the service life of the machine is greatly extended. In addition, compared with the traditional toggle link mold clamping mechanism, the mold clamping mechanism of the two-plate plastic injection molding machine has one less mold adjusting template, which greatly reduces the cost of the machine for medium and large machines. Because the movable template is disengaged from the tie rod when the mold is opened, and the movable template is locked with the tie rod by a mechanism when the high-pressure mold is locked. This mechanism is called a brake mechanism on the two-platen plastic i...
