Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an oblique translation type precision mould for a slider of an air conditioner panel. Background Art

[0002] Air conditioning is a technology system that regulates the temperature of indoor air through a refrigeration cycle or a heating cycle. The refrigeration cycle uses refrigerant to absorb heat from indoors and discharge it to outdoors through a process of compression, cooling, expansion, and heating. The heating cycle absorbs heat from outdoors and releases it indoors by reversing the refrigeration cycle. It is a technology system that changes the temperature, humidity, flow rate, cleanliness, and other states of the air to meet indoor air quality requirements and provide a comfortable indoor environment.

[0003] For example, the air-conditioning panel slider oblique translation precision mold disclosed in the publication number CN103660188A belongs to the field of plastic mold technology. Specifically, it relates to an air-conditioning panel slider oblique translation precision mold, including two major parts: a front mold and a rear mold. The front mold part is composed of a front panel and an A plate from top to bottom. The front panel is provided with a positioning ring for connecting to an injection molding machine. The upper surface of the A plate is provided with a downwardly recessed hot runner system. The interior of the A plate is provided with a front mold core. The rear mold part includes a B plate, a support plate, and a rear panel from top to bottom. A large rear mold core and a small rear mold core are provided inside the B plate, and an upper ejector plate and a lower ejector plate are also provided. A slider located directly below the product groove is provided between the large rear mold core and the small rear mold core, and a side slider, an oblique slider, and an oblique wedge block are also provided. The sliders are connected and linked in sequence through mutually matching T-slots and T-blocks. By changing the direction of the slider movement, the oblique movement of the slider is decomposed and converted into a translational movement, which greatly reduces the weight of the entire mold and reduces the volume of the mold.

[0004] Although the above-mentioned patent reduces the volume of the mold by using the front mold and the rear mold in coordination, the above-mentioned patent and most of the molds on the market mainly use the elastic force of the spring as the driving source of the ejector. First, the spring-driven ejector is easily disturbed by external factors such as debris, dust, and water droplets during use, causing the spring to deform, sag or get stuck, thereby affecting the normal operation of the ejector and affecting the service life and precision of the mold. Secondly, since the elasticity of the spring is not fixed, it is affected by factors such as temperature, humidity, load and service life, which will cause its elasticity to change, and ultimately affect the working precision and stability of the ejector. In addition, the spring-driven ejector usually requires manual adjustment and maintenance, and needs to be frequently checked, replaced and adjusted, which requires relatively high operating skills of the operator.

[0005] Therefore, in order to solve the above problems, a precise oblique translation mold for the slider of the air-conditioning panel needs to be developed urgently. Utility Model Content
