Problems solved by technology

[0002] The traditional hydraulic mold clamping mechanism only has a mold clamping cylinder without a toggle mechanism, and the clamping force is all applied to the cylinder, so it is difficult to seal the cylinder, and the required cylinder diameter is large and the manufacturing cost is high
Existing toggle mold clamping mechanism, such as the structure disclosed in Chinese patent CN2454116Y, although the required oil cylinder bore is smaller than that of the hydraulic mold clamping mechanism when reaching the same mold clamping force, there are still the following disadvantages: 1. Generally only It is suitable for horizontal installation, and has a large overall length and a large floor area; 2. If it is installed vertically, the operating station is relatively high, which is inconvenient to operate; and the movable template drives the reciprocating movement of the lower mold, and inserts are placed in the lower mold It is easy to shift and cause damage to the mold; 3. The toggle mechanism must be frequently lubricated, and thus the appearance of the whole machine is not clean and the pollution is serious

Abstract

The present invention discloses a toggle mould-closing mechanism for plastics-injection machine. It has fixed mould plate, moving mould plate, bottom plate, pull bar, closing cylinder and toggle connecting rod mechanism, and also includes piston rod and supporting frame, etc. Said invention also provides their connecting method and operation mode, it is suitable for placing insertion, and can protect said mould.

Description

technical field [0001] The invention relates to a mold clamping mechanism of a plastic injection molding machine, and is especially suitable for a mold clamping mechanism of a vertical injection molding machine. Background technique [0002] The traditional hydraulic mold clamping mechanism only has a mold clamping cylinder without a toggle mechanism, and the clamping force is all applied to the cylinder, so it is difficult to seal the cylinder, and the required cylinder diameter is large and the manufacturing cost is high. Existing toggle mold clamping mechanism, such as the structure disclosed in Chinese patent CN2454116Y, although the required oil cylinder bore is smaller than that of the hydraulic mold clamping mechanism when reaching the same mold clamping force, there are still the following disadvantages: 1. Generally only It is suitable for horizontal installation, and has a large overall length and a large floor area; 2. If it is installed vertically, the operating ...
