Miniaturized liquid silicone rubber forming machine suitable for three-plate molds

Abstract

The invention relates to a miniaturized liquid silicone molding machine suitable for a three-plate mold, including an electric box, a frame, a pneumatic three-axis manipulator, a gas-liquid pressurized cylinder, a fixed plate, a front push plate, an ejection cylinder, a middle push plate, Connecting column, front platen, middle platen, rear platen, guide sleeve, guide post and liquid silicone injection unit, the gas-hydraulic pressurized cylinder drives the front platen, middle platen to move and rear platen to close the mold, and the liquid silicone injection unit injects into the cavity Liquid silicone, the product is formed in the cavity, the gas-hydraulic booster cylinder drives the front template, the middle template moves backward and the rear template is split, and the ejector cylinder drives the middle template forward to pull out the formed product, and the pneumatic three-axis manipulator grips and molds The final product does not require manual operation in the whole process, has a high degree of automation, optimizes the structural layout design, shortens the front and rear template clamping strokes, is light and compact in size, miniaturized design is convenient to carry, does not occupy space, speeds up production, expands the scope of use, and meets the needs of customers. need.

Description

technical field [0001] The invention relates to the field of molding machines, in particular to a miniaturized liquid silicone molding machine suitable for three-plate molds. Background technique [0002] Liquid silicone molding machine is an automatic production of silicone products such as silicone pacifiers, feeding bottles, baby toothbrushes, oxygen masks, laryngeal masks, tooth pads, masks, catheters, watch straps, O-rings, valves, etc. Molding equipment, the existing liquid silicone molding machine is popular with manufacturers because of its high degree of automation and low labor intensity. It means that the forming mold of the liquid silicone molding machine is mainly composed of a front template and a rear template, and there is only one parting surface. During processing, only the front template and the rear template need to be molded and split. The three-plate mold refers to The forming mold of the liquid silicone molding machine is mainly composed of a front te...

[0002] Liquid silicone molding machine is an automatic production of silicone products such as silicone pacifiers, feeding bottles, baby toothbrushes, oxygen masks, laryngeal masks, tooth pads, masks, catheters, watch straps, O-rings, valves, etc. Molding equipment, the existing liquid silicone molding machine is popular with manufacturers because of its high degree of automation and low labor intensity. It means that the forming mold of the liquid silicone molding machine is mainly composed of a front template and a rear template, and there is only one parting surface. During processing, only the front template and the rear template need to be molded and split. The three-plate mold refers to The forming mold of the liquid silicone molding machine is mainly composed of a front template, a middle template, and a rear template. There are two parting surfaces. During processing, it is necessary to consider how the middle template cooperates with the front template and the rear template for mold clamping and parting. The structure is relatively complicated.

[0003] However, whether it is a two-plate mold or a three-plate mold, the following defects are found in the process of use: First, the structural design of the model is complex, there are many components, and the mold clamping stroke is long, resulting in large volume, difficult handling, high operating noise, and high cost. 1. High precision requirements for parts matching, and lack of practicability; Second, in order to realize automatic material retrieving, the liquid silicone molding machine needs to be equipped with a special manipulator for material reclaiming. The manipulator is expensive and inconvenient to assemble and debug. Third, when the liquid silicone molding machine produces different silicone products, it needs to replace the whole set of silicone molds, while the traditional silicone molds have complex runner structures and insert structures, and different silicone molds need to be replaced. It is necessary to fully consider its own flow channel structure and insert structure, resulting in cumbersome replacement procedures, long time-consuming, insufficient versatility, and limited application range
