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

Abstract

The invention relates to a miniaturized liquid silicone rubber forming machine suitable for three-plate molds. The miniaturized liquid silicone rubber forming machine comprises an electric box, a rack, a pneumatic triaxial manipulator, a pneumohydraulic pressure-cylinder, a fixed plate, a front push plate, an ejector cylinder, a middle push plate, a connecting pole, a front template, a middle template, a rear template, a guide sleeve, a guide pillar and a liquid silicone rubber injection unit. The pneumohydraulic pressure-cylinder drives the front template and the middle template to move for mold closing with the rear template; the liquid silicone rubber injection unit injects liquid silicone rubber into a mold cavity for molding of a product in the mold cavity; the pneumohydraulic pressure-cylinder drives the front template and the middle template to move backwards for mold closing with the rear template, and simultaneously the ejector cylinder drives the middle template to move forwards to pull out the molded product; and the pneumatic triaxial manipulator clamps the molded product. manual operation is not required during the whole process; the degree of automation is high; structure layout design is optimized; mold closing stroke of the front and rear templates is shortened; the miniaturized liquid silicone rubber forming machine is light in weight and small in size; the miniaturized design is convenient for transport; the miniaturized liquid silicone rubber forming machine occupies small space; production is accelerated; application range is widened; and requirements 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 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.

[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
