Description

A hot melt forming machine for producing plastic parts

Technical Field

The utility model relates to the technical field of washing machine production equipment, in particular to a hot-melt forming machine for producing plastic parts.

Background Art

Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants and colorants. The main component of plastic is resin, which refers to a high-molecular compound that has not been mixed with various additives. In the production process of plastic parts for washing machines, hot melt forming machines are used to assist plastics.

A hot-melt forming machine for producing plastic parts is disclosed in Chinese patent CN216267166U (publication number). The hot-melt forming machine for producing plastic parts can quickly cool the plastic parts after the forming operation is completed through a water tank, a water pump, a heat-conducting coil, heat-conducting silicone, a water inlet duct and a water outlet duct, thereby improving the efficiency of plastic part production.

However, compared with the existing technology in the related field, after the plastic parts are hot-melt formed in the mold, they need to be cooled statically before demolding. Therefore, when the plastic parts in the mold are not completely cooled, it is necessary to wait for the mold to be completely cooled before the next hot-melt forming work can be carried out, which still reduces the processing efficiency of the plastic parts.

The switching assembly 3 comprises a turntable 301. The top of the first frame 1 is rotatably connected with the turntable 301. A motor 101 is fixedly installed at the center of the interior of the first frame 1. The output end of the motor 101 is matched and connected with the center of the bottom of the turntable 301. A plurality of movable grooves 302 are provided on the outer surface of the turntable 301. A rotating frame 303 is rotatably connected to the interior of the plurality of movable grooves 302. A hot melt forming lower mold 304 is fixedly installed inside the rotating frame 303. The rotating frame 303 is connected by a plurality of movable grooves 302. The rotating shaft 305 is connected with the rotating disk 301, and the rotating disk 301 has rotating holes at positions corresponding to the multiple rotating shafts 305. Bolts 307 are threadedly connected at positions corresponding to the multiple rotating holes on the top of the rotating disk 301. The ends of the bolts 307 fit with the rotating shaft 305. The bolts 307 can be used to adjust the friction force when the rotating shaft 305 rotates, so that when the rotating shaft 305 is not subjected to force, the rotating frame 303 can maintain the existing state. A trigger wheel 306 is fixedly provided at one end of the rotating shaft 305 located outside the rotating disk 301. The trigger wheel 306 is a gear. The positions of the first frame 1 corresponding to the multiple trigger wheels 306 are fixedly installed with trigger components 4.

The trigger assembly 4 includes a connecting rod 401 fixedly mounted on the first frame 1, and a trigger sheet 402 matched with the trigger wheel 306 is fixedly mounted on one end of the connecting rod 401 away from the first frame 1. The trigger sheet 402 is a rack, and the shape of the trigger sheet 402 is arc-shaped. The trigger sheet 402 is fixedly mounted on the connecting rod 401 by bolts 307. On the one hand, the matching degree between the trigger wheel 306 and the trigger sheet 402 can be improved. On the other hand, by utilizing the meshing of the gear and the rack, each time the trigger wheel 306 contacts a trigger sheet 402, the rotating shaft 305 drives the rotating frame 303 to rotate a certain degree (when the number of rotating frames 303 is four, each time the trigger wheel 306 contacts a trigger sheet 402, the rotating shaft 305 drives the rotating frame 303 to rotate ninety degrees, and then the rotating frame 303 rotates exactly three hundred and sixty degrees when it reaches one side of the second frame 2);

A hydraulic cylinder 201 is fixedly installed on one side of the second frame 2 close to the turntable 301, and a hot melt forming upper mold 202 is fixedly installed on the output end of the hydraulic cylinder 201;

A fixed disk 5 is fixedly provided on one side of the first frame 1 close to the turntable 301, and a fan 6 is fixedly installed on one side of the top of the fixed disk 5. By using the fan 6, when the rotating frame 303 rotates less than or equal to ninety degrees, the fan 6 can blow airflow to the hot-melt molding lower mold 304 inside the rotating frame 303, thereby cooling the plastic molded parts inside the hot-melt molding lower mold 304. The fan 6, hydraulic cylinder 201, motor 101, hot-melt molding lower mold 304 and hot-melt molding upper mold 202 in this embodiment are all well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

The working process is as follows:

S1, when working, the hot melt forming upper mold 202 is controlled by the hydraulic cylinder 201 to contact the hot melt forming lower mold 304 on the turntable 301, and then hot melt forming can be performed;

S2, when the plastic part inside the hot-melt forming lower mold 304 is hot-melt-molded, the hot-melt forming upper mold 202 is reset by the hydraulic cylinder 201, and then the motor 101 controls the rotation of the turntable 301;

S3, each time the trigger wheel 306 contacts a trigger sheet 402, the rotating shaft 305 drives the rotating frame 303 to rotate a certain degree (when there are four rotating frames 303, each time the trigger wheel 306 contacts a trigger sheet 402, the rotating shaft 305 drives the rotating frame 303 to rotate 90 degrees, and then the rotating frame 303 reaches one side of the second frame 2 and rotates exactly 360 degrees);

S4, using the fan 6, when the rotating frame 303 rotates less than or equal to 90 degrees, the fan 6 can blow airflow toward the hot melt molding lower mold 304 inside the rotating frame 303, so as to cool down the plastic molded part inside the hot melt molding lower mold 304;

S5. When the rotating frame 303 rotates 180 degrees, the plastic molded part can be automatically separated from the hot melt molding lower mold 304 under the action of its own gravity. Then, when in use, a conveyor belt can be set under the hot melt molding lower mold 304, so as to realize assembly line production operation;

S6. Continuous operation can be performed through multiple rotating frames 303, so that when one of the hot melt forming lower molds 304 is cooling, another hot melt forming lower mold 304 can quickly fill the vacant position, thereby allowing the device to perform continuous hot melt forming operations, effectively improving the hot melt forming efficiency of the equipment;

S7. The friction force of the rotating shaft 305 when rotating can be adjusted by using the bolt 307, so that when the rotating shaft 305 is not subjected to force, the rotating frame 303 can maintain the existing state.
