Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner housing injection molding device, and in particular to an air conditioner housing injection molding device. Background Technology

[0002] In the production of air conditioner casings, injection molding is a crucial step, and its efficiency and product quality directly impact production benefits. Currently, air conditioner casing injection molding equipment faces several problems in practical applications. Firstly, the injection molding material requires preheating to ensure optimal injection molding results. The heating plates in the preheating chamber are prone to aging and damage after prolonged use, requiring periodic replacement. However, traditional heating plate installation structures are complex, relying heavily on bolts and other fasteners. Replacement requires specialized tools for gradual disassembly and installation, making the process cumbersome and time-consuming. This leads to frequent downtime due to maintenance, severely impacting overall injection molding efficiency. Simultaneously, some fixed structures are prone to loosening under long-term vibration, causing heating plate displacement, affecting preheating stability, and consequently reducing the preheating effect of the material, negatively impacting the subsequent injection molding quality. Secondly, after injection molding, the molded air conditioner casing needs to be demolded from the mold. Traditional demolding methods rely heavily on manual operation, requiring workers to manually peel or pry open the molded shell. This is not only labor-intensive and inefficient, making it difficult to adapt to the needs of mass production, but also makes it difficult to control the force and angle during manual operation, easily leading to shell deformation and surface scratches, affecting product quality consistency. In addition, forceful demolding can also cause hard damage to the mold, shortening its lifespan, increasing equipment maintenance costs, and hindering the improvement of the continuity and automation level of injection molding production. Therefore, we propose an air conditioner shell injection molding device to solve this problem. Utility Model Content

Pulling the pull plate causes the sliding plate to slide within the frame and compress the first spring, causing the insert plate to be pulled out from the heating plate. At the same time, the frame is lifted upward, causing the insert block to detach from the heating plate. At this time, the round plate slides within the slide groove and stretches the second spring, allowing the old heating plate to be removed. This structure is simple and easy to operate, facilitating the quick installation and removal of the heating plate, significantly shortening the heating plate replacement time, reducing the downtime of the device due to maintenance, improving the overall injection molding production efficiency, and achieving double fixation to prevent loosening or displacement due to vibration or other factors during the operation of the preheating box, ensuring that the heating plate stably performs its heating function and guaranteeing the preheating effect of the raw materials. In this invention, an air conditioner housing injection molding device is provided with a demolding assembly. When a dual-axis motor is started, its output shaft drives two sets of screws with opposite threads to rotate. This causes two sets of threaded plates to move towards each other on the screws. The threaded plates drive a connecting rod to rotate, which pushes a fixed block upwards. The fixed block then drives a moving plate upwards, and the moving plate, through a fixed rod, pushes the demolding plate upwards, ejecting the molded air conditioner housing from the mold groove. This achieves mechanized demolding, eliminating the need for manual peeling of the molded housing, significantly shortening demolding time, reducing manual intervention, improving the continuity and automation level of injection molding production, adapting to batch production needs, and avoiding mold damage caused by manual forceful demolding, indirectly extending mold life and reducing equipment maintenance costs.

[0015] In this embodiment, cylinders 8 are provided on both sides of the lower mold 4. The output ends of the two sets of cylinders 8 are fixedly connected to the bottom of the top plate 1. Four sets of guide rods are fixedly installed on the bottom of the top plate 1. The four sets of guide rods are slidably installed inside the lower mold 4 to facilitate the closing of the upper mold 3 and the lower mold 4. A bracket is fixedly installed inside the bottom end of the rectangular groove. The bracket is fixedly connected to the dual-axis motor 708.
