Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding mechanism for an automotive parts injection molding machine. Background Technology

[0002] Injection molding is a method of industrial product manufacturing, typically using rubber injection molding and plastic injection molding. Injection molding can be further divided into injection molding compression molding and die casting. An injection molding machine is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through an injection molding machine and molds.

[0003] Existing automotive parts injection molding equipment cannot first crush the injection plastic. The plastic raw material particles are of different sizes, and some larger particles cannot be melted at the same time as others, resulting in uneven heating during the heating process. This can easily cause air pockets to form inside the finished product, affecting the injection molding quality. Therefore, an injection mechanism for an automotive parts injection molding machine is proposed. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] This utility model provides an injection molding mechanism for an automotive parts injection molding machine. A drive motor rotates a crushing roller, which in turn drives another crushing roller via gears. The rotating crushing rollers crush the raw material, facilitating its entry into the injection molding machine's storage tank for melting. This ensures uniform heating, improving production efficiency and quality. Please refer to [link / reference]. Figures 1-5 It includes: injection molding machine 100, storage tank 200 and crushing mechanism 300.

[0033] The storage tank 200 is installed on the injection molding machine 100. The storage tank 200 includes a tank body 210 and a feed pipe 220. The feed pipe 220 is installed on the top left side of the tank body 210.

[0034] Among them, the storage tank 200 is a heating tank of the injection molding machine, and the solid material is melted inside the storage tank 200.

[0035] The crushing mechanism 300 is installed on the feed pipe 220. The crushing mechanism 300 includes a crushing roller 310, a drive motor 320 and a gear 330. The crushing roller 310 is symmetrically arranged inside the tank 210. The drive motor 320 is installed at the outer end of one side. The crushing roller 310 is provided with meshing gears 330.

[0036] The drive motor 320 drives the crushing roller 310 to rotate, the crushing roller 310 drives the gear 330 to rotate, the gear 330 meshes and drives the other gear 330 to rotate, and the other gear 330 synchronously drives the crushing roller 310 on the other side to rotate, thereby crushing the material through the rotating crushing roller 310.

[0037] The top of the storage tank 200 is provided with a sliding hole 230, and a lifting mechanism 400 is provided on the sliding hole 230. The lifting mechanism 400 is connected to the gear 330. Specifically, the lifting mechanism 400 includes a turntable 410, an eccentric shaft 420, a swing rod 430, a lifting rod 440, a pressure plate 450, and an inclined plate 460. The turntable 410 is fixedly connected to the gear 330 on one side. The eccentric shaft 420 is provided on the turntable 410. The swing rod 430 is rotatably connected to the eccentric shaft 420. The lower end of the swing rod 430 is rotatably connected to the lifting rod 440. The lifting rod 440 is slidably connected in the sliding hole 230. The pressure plate 450 and the inclined plate 460 are respectively provided on the upper and lower sides of the lifting rod 440.

[0038] Among them, the lifting rod 440, the pressure plate 450 and the inclined plate 460 are all made of high-temperature resistant metal parts. When the gear 330 rotates, it synchronously drives the turntable 410 to rotate. The turntable 410 synchronously drives the eccentric shaft 420 to rotate in a circle. The eccentric shaft 420 drives the lifting rod 440 to rise and fall through the swing rod 430. The lifting rod 440 synchronously drives the pressure plate 450 and the inclined plate 460 to rise and fall. The pressure plate 450 moves up and down on the surface of the molten liquid, pressing the material floating on the surface into the molten liquid. The inclined plate 460 stirs the molten liquid to facilitate the melting of the material.

[0039] The pressure plate 450 and the inclined plate 460 are both located inside the tank body 210. The pressure plate 450 and the inclined plate 460 are evenly distributed outside the lifting rod 440, so that the pressure plate 450 and the inclined plate 460 are in full contact with the molten liquid.

[0040] Because it is necessary to adjust the liquid level inside the tank 210, a transparent viewing window is provided on the outer wall of the tank 210. The transparent viewing window is an explosion-proof window, which allows the liquid level to be observed.

[0041] To facilitate material drop, the tank 210 and feed pipe 220 are designed in a funnel shape, wider at the top and narrower at the bottom, to allow the material to fall down the slope.

[0042] To prevent external impurities from falling into the tank 210, an end cap is provided at the top of the feed pipe 220. The end cap is hinged to the feed pipe 220 and is used to seal the feed pipe 220 after feeding.

[0043] In practical use, the injection molding material is put into the feed pipe 220. The drive motor 320 drives the crushing roller 310 to rotate. The crushing roller 310 drives the gear 330 to rotate. The gear 330 meshes and drives the other gear 330 to rotate. The other gear 330 synchronously drives the other crushing roller 310 to rotate. The material is crushed by the rotating crushing roller 310. The crushed material falls into the tank 210. When the gear 330 rotates, it synchronously drives the turntable 410 to rotate. The turntable 410 synchronously drives the eccentric shaft 420 to rotate circumferentially. The eccentric shaft 420 drives the lifting rod 440 to rise and fall through the swing rod 430. The lifting rod 440 synchronously drives the pressure plate 450 and the inclined plate 460 to rise and fall. The pressure plate 450 moves up and down on the surface of the melt, pressing the material floating on the surface into the melt. The inclined plate 460 stirs the melt to facilitate the melting of the material.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
