Description

Technical Field

[0001] This invention relates to rubber injection equipment, and more particularly to a 250T dual-station single-hydraulic-pressure controlled 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] Existing comparative documents use a dual-station processing platform, but single-item injection molding cannot be integrated with new injection configurations to achieve automated and efficient production. Furthermore, existing dual-station injection molding machine designs all employ a one-to-one injection hydraulic configuration, which increases manufacturing costs, requires more space, and restricts on-site layout. Summary of the Invention

[0004] The purpose of this invention is to provide a 250T dual-station single-hydraulic-pressure controlled rubber injection molding machine, which solves the problems of high-quality assembly design of dual-station injection structure and single-oil-controlled dual-station configuration.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a 250T dual-station single hydraulic control rubber injection molding machine, including a combined protective fence body, a multi-directional hydraulic control structure located within the combined protective fence area, and one or more sets of rubber injection molding mechanisms connected to the multi-directional hydraulic control structure. The multi-directional hydraulic control structure includes a main control box, an oil storage tank located at the rear end of the main control box, a partitioned conveying oil tank located at the rear of the oil storage tank, a branch oil circuit structure connected to the rear end of the partitioned conveying oil tank and connected to the rubber injection molding mechanism, and a hydraulic control device located in the multi-directional hydraulic control structure.

[0006] The rubber injection molding mechanism includes an injection molding frame structure and a demolding frame structure.

[0007] The injection molding machine frame structure includes an injection equipment connecting base, an injection bottom control oil tank located on the upper part of the injection equipment connecting base, an injection body base frame structure, and an upper injection body structure.

[0008] The injection body base structure includes an injection outer support connecting frame located on the upper part of the injection equipment connecting base, an injection middle oil control cylinder located inside the injection outer support connecting frame and connected to the injection bottom oil control tank, and a bottom mold connecting structure located on the upper part of the injection outer support connecting frame.

[0009] The bottom mold connection structure includes a bottom surface control connection seat, a bottom mold changing drive structure located at the rear end of the bottom surface control connection seat, and a locking seat located on the injection external support connection frame outside the bottom surface control connection seat.

[0010] The upper injection body structure includes a support column assembly located on the upper part of the injection body base frame structure, an upper injection mold base located on the upper part of the support column assembly, an upper control cylinder located on the upper part of the upper injection mold base and extending into it, and a feeder.

[0011] The demolding frame structure includes a demolding base, a demolding base frame body on top of the demolding base, a demolding base plate on top of the demolding base frame body, a demolding seat body on top of the demolding base plate and connected to the demolding base frame body, and a flipping bracket.

[0012] The branch oil circuit structure includes a branch front delivery pipe, a booster pipe body located at the inner end of the branch front delivery pipe, a branch booster pump body located on the upper part of the booster pipe body, and a control valve body located between the inner end of the branch front delivery pipe and the booster pipe body.

[0013] The hydraulic control equipment includes a main control booster motor located on the upper part of the oil storage tank, an input oil pump located on the upper part of the oil storage tank, an output oil pump located on the upper part of the oil storage tank, and a pressure divider controller located on the upper part of the zone delivery oil tank.

[0014] The beneficial effects of this invention are as follows: A single oil control system can control multiple injection molding units, resulting in a higher production capacity than a single rubber injection molding machine within the same timeframe. Furthermore, the vulcanization waiting time of each injection molding unit is fully utilized, eliminating or reducing ineffective working time, leading to higher production efficiency. Since the two injection molding units share some equipment, their energy consumption is lower than that of two independent rubber injection molding machines, thus improving the overall efficiency of the equipment. It is also convenient to operate, reducing procurement and operating costs. Only one operator is required, resulting in lower labor costs; therefore, the procurement and operating costs of this double-seat rubber injection molding machine are both lower.

[0015] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description
