Miniaturized liquid silicone rubber forming machine suitable for two-plate mold

Abstract

The invention relates to a miniaturized liquid silicone rubber forming machine suitable for a two-plate mold. The miniaturized liquid silicone rubber forming machine comprises an electricity box, a rack, a pneumatic triaxial manipulator, a pneumohydraulic pressure cylinder, a fixed plate, a push plate, a connecting column, a front mold plate, a heating ring, a rear mold plate, a guide sleeve, a guide column and a liquid silicone rubber injection unit. Compared with an existing complex-structure liquid silicone rubber forming machine, the pneumohydraulic pressure cylinder drives the front moldplate to move to be combined with the rear mold plate, the liquid silicone rubber injection unit injects liquid silicone rubber into a mold cavity, the temperature of the heating ring rises for heating, a product is formed in the mold cavity, and the pneumatic triaxial manipulator clamps the formed product. Manual operation is not needed in the whole process, the automation degree is high, structure layout design is optimized, the mold combining process of the front mold plate and the rear mold plate is shortened, the size is light and small, carrying is convenient through the miniaturized design, space is not occupied, a runner structure and an insert structure do not need to be considered during mold replacement, production speed is increased, the use range is widened, and needs are met.

Description

technical field [0001] The invention relates to the field of molding machines, in particular to a miniaturized liquid silicone molding machine suitable for two-plate moulds. 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.

[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
