Description

Technical Field

[0001] The utility model relates to the field of mold locking structure and processing, in particular to a two-plate type mold locking structure device and molding equipment. Background Art

[0002] At present, the support of the injection molding mobile template is still a sliding foot type with steel belt, which relies on the lubricating oil film on the contact surface to achieve sliding when moving. This mobile structure has high resistance, the attached oil film is easy to be damaged, the steel belt is easy to wear, and the production maintenance and servicing costs are high; and the sliding of the sliding foot requires left and right limit guides, and the structure is redundant; even if linear guide rails are used for support, due to the length of the supporting anti-tilting sliding foot support plate connected to the movable template linear guide slider, when loading thin molds, the supporting anti-tilting sliding foot support plate of the slider will support the fixed support foot of the fixed template when moving forward, and it cannot move forward, and it cannot accommodate thinner molds; in order to achieve the necessary loading of thin molds, the only way to overcome this problem is to add mold pads on the fixed template and / or the movable template mold surface, and to thicken the mold in disguise. In this way, there is an extra layer of fixation, which increases the risk of unsafe sliding of the fixed mold during the opening and closing of the mold; at the same time, it also increases the running load of the movable template, and the power to drive the movable template needs to be strong enough. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a two-platen locking structure device and molding equipment, which have a simple structure, can reduce the power of the movable template, and have high guiding accuracy, so that the power source is small and energy-saving; and the movable template is subjected to small impact inertia during the opening and closing action, and the eccentric load force on the pull rod is greatly reduced, thereby extending the service life of the pull rod and the template; and it is easy to realize the loading of thin molds, etc.

And the space for the linear guide rail support guide assembly (6) to extend forward is provided as the linear guide extension distance B. The left and right offset distance A of the fixed plate support foot (7) and the fixed plate support boss (8) of the clamping lower frame assembly is determined when designing. The power provided by the mold shifting cylinder assembly (2) drives the movable mold plate assembly (1) to move forward and backward on the linear guide rail support guide assembly (6); the mold locking high-pressure cylinder assembly (4) is installed on the fixed mold plate (3) to provide a force to overcome the expansion force during molding.
