Description

Technical Field

[0001] This utility model relates to the field of rubber injection equipment, and in particular to a large-tonnage double-sided double-layer ejection rubber injection molding machine. Background Technology

[0002] Currently, CN105666783B discloses a double-seat rubber injection molding machine, including injection molding units and operating devices. The injection molding unit includes an injection device, a mold closing device, a mold moving device, an ejection mechanism, a mold, and an oil tank. This double-seat rubber injection molding machine also includes a main pump station and an auxiliary pump station. There are two injection molding units and one operating device. The operating device is connected to both injection molding units via an electrical control system. The oil tanks on the two injection molding units are connected by connecting pipes. The injection devices and mold moving mechanisms of both injection molding units are connected to the main pump station via pipelines, and the ejection mechanisms of both injection molding units are connected to the auxiliary pump station via pipelines. With increasingly higher production cost requirements, higher performance demands are being placed on rubber injection molding machines used to produce rubber molded products, with a desire for more energy-efficient and high-performance machines. To reduce costs, many small and medium-sized enterprises (SMEs) have adopted semi-automatic rubber injection molding machines (PIMs), where products are automatically formed and finished products are manually removed. Currently, most PIMs operating in this manner use a single injection head configuration, meaning each machine is equipped with only one injection unit. Since the rubber injection molding process includes a vulcanization step, which requires maintaining pressure for a period of time, operators often have to pause while operating a single machine to wait for the vulcanization process to complete. This results in wasted time during the product formation cycle, which is completely squandered in a one-person-one-machine operation model. To eliminate this wasted time, some manufacturers have adopted a one-person-multiple-machine operation model, where one person manages and operates two or more PIMs simultaneously. However, this model is difficult to apply to semi-automatic PIMs with manual part removal because multiple independent PIMs lack linkage constraints, making it difficult to ensure coordination and synchronization between them.

[0003] The existing comparative documents use a dual-station processing platform, but single injection molding cannot produce two products in the same cycle. Utility Model Content

[0004] The purpose of this invention is to provide a large-tonnage double-sided double-layer ejection rubber injection molding machine to solve the problem of multiple operation and processing ranges in the configuration of a dual-station injection structure.

The double-sided double-layer rubber injection molding mechanism includes an injection molding main body mechanism and double-sided operating stations arranged at the front and rear ends of the injection molding main body mechanism. The double-sided operating stations include a left ejection operating station and a right ejection operating station. Each of the left ejection operating station and the right ejection operating station is provided with a kerosene preheating structure connected to the hydraulic control structure.

The lower forming bottom mold is externally connected to the main mold column group and is provided with a lower mold platform.

[0008] The upper forming mold structure includes an upper forming bottom mold, an upper forming upper mold base, and an upper forming bottom mold replacement base located at the lower part of the upper forming bottom mold;

[0009] An upper protective column assembly is installed between the upper mold base and the lower mold platform.

[0012] The beneficial effects of this utility model are as follows: The main structure of the equipment can automatically install and remove molds, and is equipped with a double-sided, double-layer mold ejection function; the hot plate hydraulic lifting mold structure and synchronous exhaust structure enable automatic mold entry and exit, with the upper mold flipping at 45° after exiting; sliding plate entry and exit, and hydraulic motor entry and exit.
