Description

Technical Field

[0001] The utility model relates to the technical field of shaping devices, in particular to a shaping device for processing polyurethane sponges. Background Technique

[0002] The shaping device for processing polyurethane sponges is a device used in the manufacturing process of polyurethane sponges. The main purpose is to form the polyurethane raw material into the required shape and structure. The shaping device can be designed in different forms according to specific requirements. It usually includes a mold and processing equipment for injecting liquid polyurethane material into the mold and forming the final sponge product after reaction curing. The shaping device for processing polyurethane sponges usually realizes shaping by extrusion. Extrusion is a common processing method. By expanding and curing the polyurethane raw material in the mold of the forming device, a sponge product with a specific shape and density is manufactured.

[0003] However, when the existing shaping device for processing polyurethane sponges prepares workpieces, it is not convenient to quickly demold the formed workpieces, which has certain limitations. When taking the formed workpieces, it affects the work efficiency to a certain extent.

[0004] Patent document CN217097987U discloses a polyurethane sponge shaping and processing device, "including a bottom plate, L-shaped side plates arranged on both sides of the bottom plate, a rectangular frame that can be lifted up and down is arranged on the opposite surfaces of the two side plates, a power mechanism for driving the lifting of the rectangular frame is arranged on the side plates, a shaping pressing plate is detachably installed on the rectangular frame, and left and right limiting components for limiting the sponge block to be processed are arranged at both ends of the opposite surfaces of the rectangular frame and the bottom plate. The left and right limiting components include two pairs of strip-shaped rods slidably arranged at both ends of the opposite surfaces of the rectangular frame and the bottom plate. A vertical telescopic frame is arranged between each pair of strip-shaped rods, and a first fixing component for fixing the upper strip-shaped rod is arranged on the rectangular frame. Front and rear limiting components for limiting the sponge block are arranged at the front and rear ends of the inner surfaces of the two pairs of strip-shaped rods. This device is convenient for limiting the sponge during sponge processing, avoiding the offset of the sponge during the processing process, and has a good shaping and processing effect", however, the polyurethane sponge shaping and processing device in the above-mentioned published literature mainly considers avoiding the offset of the sponge during the processing process, but does not consider the problem of quick demolding. Therefore, it is necessary to research a shaping device for processing polyurethane sponges. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shaping device for processing polyurethane sponges to solve the technical problem of inconvenient and quick demolding proposed in the above background technique.

[0012] Preferably, an installation groove is fixedly installed on the top of the support plate, a fan is arranged inside the installation groove, and the fan is electrically connected to the controller. The output end of the fan is communicated with the flow channel.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model facilitates the rapid demoulding of the shaping device for processing polyurethane sponge through the installed push plate and the second electric push rod. When using the shaping device for processing polyurethane sponge to shape the polyurethane sponge, after placing the polyurethane sponge raw material to be processed inside the shaping mold, the first electric push rod works to drive the pressing plate to move, and the pressing plate moves to extrude and cure the polyurethane sponge inside the shaping mold.

[0015] 2. The utility model facilitates the removal of debris through the installed fan and exhaust holes. After the push plate moves out of the shaping die, the fan works to generate wind force, which flows into the flow groove. Through the exhaust holes, the wind force flows to the surface of the push plate, thereby removing the adsorbed substances on the push plate. At the same time, the third electric push rod works to push the support plate to move, adjust the position of the flow groove, and make the exhaust holes parallel to the top of the workbench, so as to remove the debris adsorbed on the top of the workbench, thereby improving the cleaning efficiency.
