Problems solved by technology

[0003] In the prior art, the clamping device is usually composed of two half-ring structures. During the process of clamping and opening, the two half-rings often cannot achieve the synchronous effect, which will lead to inconsistencies in the process of mold closing and mold opening. Smooth, easy to cause damage to the mold or tie rod, and also produce some noise

Embodiment Construction

[0028] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the invention is not limited to these embodiments.

[0029] Such as Figure 2-4 As shown, a new type of direct open injection molding machine synchronous clutching device, including:

[0030] The movable template 100 drives the mold to move towards the fixed mold during the mold closing process, and moves away from the fixed mold during the mold opening process.

[0031] The pull rod 200 passes through the movable template 100 and is used to guide the movable template 100, and guides the movement of the movable template 100 through the pull rod 200, thereby realizing the process of mold closing and mold opening.

[0032] Engagement device, the engagement device is installed in the moving template 100, the engagement device includes two half-engagement nuts 300, when the injection m...

Abstract

The invention discloses a novel direct opening type injection molding machine synchronous hooping device. The problems that in the prior art, a hooping device in an injection molding machine cannot besynchronous, consequently, a die is damaged and noise is generated are solved. The novel direct opening type injection molding machine synchronous hooping device comprises a movable die plate, a pullrod, a hooping device and a synchronous device. Due to the fact that sliding grooves are formed in the inner side of a pull rod hole, two semi-hooping nuts can only move in the opening direction of the sliding grooves due to sliding blocks, meanwhile, a synchronous rotary disc is arranged so that the two semi-hooping nuts can be driven to move synchronously, various kinds of damage and noise generated when synchronization is not conducted are prevented, the two semi-hooping nuts are arranged in the pull rod hole, the length of a pull rod can be shortened, and therefore the length of the wholemachine is shortened; and when the two semi-hooping nuts are used for hooping the pull rod, the two semi-hooping nuts are fixed to the pull rod under the cooperation of protrusions and grooves, and the hooping effect of the two semi-hooping nuts is better.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a novel direct-opening type injection molding machine synchronous clutching device. Background technique [0002] The two-platen injection molding machine is one of the best solutions for large injection parts in the injection molding machine industry. As attached in the manual figure 1 As shown, in the prior art, the main working parts of the two-platen injection molding machine include: injection part (1), head plate (3), second plate (6), tie rod (5), clamping device (7), clamping Oil cylinder (2) and mold (4). When the machine is closing the mould, the holding device (7) will hold the tie rod (5) tightly, and apply a driving force to the tie rod (5) through the clamping oil cylinder (2) to realize the mold closing. When the machine opens the mold, the holding device (7) is opened, and the second plate (6) is driven by the oil cylinder to separate the mold. [000...
