Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine for producing polyurethane shells. Background Art

[0002] Injection molding is a manufacturing process for making parts from plastics and other materials, in which molten material (e.g., plastic, metal, ceramic) is injected into a mold under high pressure. Injection molding is performed by an injection molding machine, which clamps the mold parts together and injects the molten material into the mold. Typically, the mold is held together by mechanical forces applied to the mold by a platen. The molten material is injected into the mold by an injection device. Once the molten material cools in the mold, the mold is opened (e.g., the first mold part and the second mold part are separated from each other), and the molded part is removed.

[0003] When using existing injection molding machines, on the one hand, there is a lack of drying during the injection molding process, which makes the raw materials easy to become moist and cause them to clump together, which in turn causes material discharge blockage or adhesion to the inner wall of the container. On the other hand, after long-term use, there are many raw material attachments on the inner wall of the injection barrel, which wastes raw materials and is inconvenient to clean, thereby reducing the utilization efficiency of the injection molding machine.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention provides a feeding mechanism, pours the injection molding raw materials into the storage tank, turns on the hot air blower to pass dry warm air into the storage tank, and the motor drives the block removal component to rotate, so as to break up the large blocks of the injection molding raw materials and enter the drying component. After the moisture on the surface of the injection molding raw materials is dried, it falls to the bottom of the storage tank, thereby realizing the layered discharge of the injection molding raw materials, avoiding the injection molding raw materials from always piling up together, and the re-appearance of agglomeration in the process of waiting for the loading, which is easy to block and affect the loading, resulting in delays in the injection molding process. At the same time, the scraping component scrapes the bottom of the inner wall of the storage tank to make it discharge completely, thereby avoiding the injection molding raw materials from adhering to the inner wall of the storage tank, resulting in waste of raw materials.

[0014] 2. The present invention sets a block removal assembly, and the first slider and the second slider rotate on the outer wall of the fixed block. The angle between the first slider and the second slider is always maintained at 180 degrees, driving the stirring plate to stir the injection molding raw materials that have just been loaded, and assisting the injection molding raw materials to pass through the sieve plate. At the same time, the clapping plate slaps and knocks the large pieces of clumped raw materials to break them up and pass through the sieve plate. The protrusions set on the clapping plate can prevent the injection molding raw materials from being stuck in the holes of the sieve plate, so that the injection molding raw materials remain dispersed, and prevent large pieces of injection molding raw materials from being difficult to discharge, resulting in blockage of the discharge pipe.

[0015] 3. The present invention sets a drying component, the hot air blower is turned on, and dry hot air is introduced into the storage tank. The ring drives the scraper to rotate, and the scattered injection molding raw materials are stirred in the air permeable groove. The spiral scraper is convenient for turning the raw materials up and down, thereby increasing the contact rate with the hot air, facilitating the rapid drying of the surface of the injection molding raw materials, and at the same time enhancing the hot melt effect and improving the working efficiency of the device. A fan-shaped hole is provided at the bottom of the air permeable groove, which is the same shape as the baffle. The baffle blocks the fan-shaped hole during drying. After drying, the baffle rotates to allow the injection molding raw materials to enter the bottom of the storage tank from the fan-shaped hole, thereby enhancing the drying inside the storage tank, avoiding re-agglomeration, and extending the storage time of the injection molding raw materials.

[0016] 4. The present invention sets a scraping component, and uses a telescopic rod to control the telescopic plugging head to block and open the discharge pipe, so as to control the discharge speed. The special-shaped column is inserted into the interior of the discharge pipe and moves up and down with the plugging head, so as to stir the injection molding raw materials in the discharge pipe, further prevent blockage and control the discharge speed. When the injection molding raw materials are no longer added, the plugging head rotates to drive the scraper rod to scrape against the inner wall of the storage tank and the inner wall of the discharge pipe, so as to prevent the injection molding raw materials from adhering to the inner wall of the storage tank and causing incomplete discharge. When the plugging head descends, the scraper rod fits with the groove opened on the plugging head, which does not affect the plugging head to prevent the injection molding raw materials from being discharged.

[0017] 5. The present invention sets a feeding mechanism, and the fixed rod pushes the workpiece out and drops it downward. Initially, the reel is located above the material trough, and the receiving net catches the workpiece, which cushions the fall of the workpiece. Then the reel drops, and the second telescopic column contracts to drive the material trough to rotate, which will slide the workpiece out for use, preventing the workpiece from falling directly into the machine, causing the newly formed workpiece to be easily deformed and affecting product quality.

The hot air blower 301 is turned on to pass dry hot air into the storage tank 302, and the sleeve ring 3071 drives the scraper 3072 to rotate, so as to disperse the scattered injection molding material in the air permeable The raw materials are stirred in the groove 3073, and the spiral scraper 3072 is convenient for turning the raw materials up and down, so that the surface of the injection molding raw materials can be dried quickly. The telescopic rod 3081 is used to make the telescopic control plug 3082 block and open the discharge pipe 309, so as to control the discharge speed. The special-shaped column 3083 is inserted into the inside of the discharge pipe 309 and moves up and down with the plug 3082, so as to stir the injection molding raw materials in the discharge pipe 309, further prevent blockage and control the discharge speed. When the injection molding raw materials are no longer added, the plug 3082 rotates to drive the scraper 3085 to scrape against the inner wall of the storage tank 302 and the inner wall of the discharge pipe 309, so as to prevent the injection molding raw materials from adhering to the inner wall of the storage tank 302 and causing incomplete discharge.
