Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine for processing fluororubber products. Background Art

[0002] In the production and processing of fluororubber products, injection molding is a key manufacturing process, and its efficiency and product quality have a vital impact on the entire production process.

[0003] In the heat dissipation link of traditional fluororubber injection molding machines, the heat dissipation process usually requires manual operation to start the heat dissipation equipment. The operator needs to pay attention to the injection progress at all times and manually start the fan and other heat dissipation devices after the injection is completed. This not only increases the operator's workload, but also easily leads to untimely heat dissipation startup. Some companies choose to keep the cooling device on. The cooling device continues to run when heat dissipation is not needed, consuming a large amount of electricity and causing energy waste. In response to the shortcomings of the existing technology, the present invention provides an injection molding machine for processing fluororubber products to solve the above problems. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an injection molding machine for processing fluororubber products.

At this time, the first circuit board and the second circuit board are connected and conductive through the cooperation of the magnetic conductive head and the magnetic conductive port. The fan automatically starts working to dissipate heat from the mold. This automatically triggered heat dissipation does not require manual intervention, can timely reduce the mold temperature, and can also avoid energy waste caused by the constant opening of the cooling device. At the same time, after the heat dissipation is completed, under the action of the first spring, the support plate drives the mold back to its original position, ready for the next injection, thereby achieving continuity and efficiency of the production process.

[0089] The mold box cover 8 and the mold box body 9 are provided with a locking assembly 11 to ensure the sealing and stability of the mold during the molding process. The locking assembly 11 includes:

[0090] The lock body 1101 is fixedly connected to the mold box body 9 and provides a mounting position for the lock tongue 1102;

[0091] The locking cap 1103 is fixedly connected to the mold box cover 8 and cooperates with the lock body 1101 to achieve the connection between the mold box cover 8 and the mold box body 9;

By moving the lever 1104, the sliding of the locking block 1106 can be controlled to realize the unlocking operation of the mold box cover 8 and the mold box body 9.

[0097] When the injection molding machine for processing fluororubber products is used, the operator puts the fluororubber raw material to be processed into the barrel 4, and the raw material enters the shell 301 through the feeding pipe 401 at the bottom of the barrel 4. At this time, the heating ring 305 starts to work, heating the rubber raw material in the shell 301 to a suitable temperature to ensure that the rubber has good fluidity and molding quality. At the same time, the mold box cover 8 is movably connected to the mold box body 9 and fixed by the lock assembly 11. The lever 1104 is toggled and the lever 1104 is in the slide groove 11. 05, driving the locking block 1106 to slide in the locking cap 1103, overcoming the elastic force of the second spring 1107, inserting the locking tongue 1102 into the locking cap 1103, loosening the lever 1104, and the elastic force of the second spring 1107 to reset the locking block 1106, cooperating with the locking tongue 1102 to achieve the locking of the mold box cover 8 and the mold box body 9, starting the motor 306, and the motor 306 drives the extrusion threaded rod 303 connected to the housing 301 to rotate. As the extrusion threaded rod 303 rotates, the rubber liquid in the housing 301 is squeezed. The rubber liquid is pushed to flow toward the nozzle 302. The rubber liquid passes through the nozzle 304 at the bottom of the nozzle 302 and is injected into the mold through the injection hole 901. After the injection starts, the weight of the rubber liquid drives the mold to press the support plate 5 downward. When the injection is completed, the first spring 6 is compressed to the bottom under the gravity of the mold. At this time, the magnetic conductive port 704 on the first circuit board 702 and the second circuit board 706 are connected and conducted through the cooperation with the fan 705. The power supply 701 is connected through the second circuit board 706. At this time, the fan 705 starts to work and starts to dissipate heat from the mold. When the heat dissipation is completed, the mold box cover 8 is opened and the push rod 1001 on the mold box body 9 is pushed. The push rod 1001 drives the push plate 1003 fixed thereon to slide in the mold box body 9. The push plate 1003 contacts the molded rubber product. As the push rod 1001 continues to push, the molded rubber product is pushed out of the mold, completing the demoulding. After the mold is taken out, due to weight reasons, under the action of the first spring 6, the support plate 5 drives the mold back to its original position for the next injection.
