Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold for an air conditioner upper and lower air direction plate. Background Technology

[0002] Current air conditioner ventilator molds typically employ a rear mold single ejector plate structure, capable of ejection. While this meets the demolding requirements of conventional products, traditional solutions are forced to use a front mold slider mechanism when the front mold area contains densely packed hooks (such as multiple functional hooks at the bottom of the ventilator). Because the slider assembly occupies excessive space, it compresses the mold's cooling water channel layout, leading to uneven water channel distribution, reduced product cooling efficiency, and extended molding cycle. The complex movement of multiple slider assemblies reduces the overall rigidity of the mold, increasing the risk of mold collisions. Furthermore, the workload for precision machining of the sliders and grinding of mating surfaces increases dramatically. Therefore, this design results in a complex mold structure, a large machining workload, insufficient mold strength, and affects the water channel design position, leading to uneven cooling and increased molding cycle.

This patent does not involve the locking structure cooperation of the hook and the inclined ejector. Utility Model Content

[0004] The purpose of this utility model is to provide an air conditioner up and down air direction plate mold to solve the shortcomings of the existing technology, such as complex structure, insufficient mold strength and high processing cost.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An air conditioner top and bottom airflow deflector mold includes a front mold and a rear mold for product forming;

[0007] The front mold includes an upper fixed plate and an A plate stacked sequentially. A front mold ejector assembly is provided in the cavity formed between the upper fixed plate and the A plate. The front mold ejector assembly includes a front mold ejector plate and a front mold inclined ejector assembly. The front mold ejector plate moves up and down along the side wall of the cavity. One end of the front mold inclined ejector assembly is slidably connected to the A plate, and the other end of the front mold inclined ejector assembly is connected to the front mold ejector plate.

[0008] The rear mold includes a lower fixed plate and a B plate stacked sequentially, and a rear mold ejector pin assembly is provided in the cavity formed between the lower fixed plate and the B plate.

[0010] The bottom of the product is provided with multiple hooks, and the end of the front mold inclined ejector assembly that is slidably connected to plate A is provided with a groove that mates with the hooks.

[0011] When the mold is closed, the hook engages with the slot to form a mold-locking structure. When the mold is demolded, the slot separates from the hook of the product.

[0012] In one embodiment of this utility model, a front mold limiting block is provided below the front mold ejector plate. When the front mold limiting block contacts plate A, the front mold ejector plate stops moving downward.

[0013] In one embodiment of this utility model, a nylon opening and closing device is provided at the upper end of the B plate, and the nylon opening and closing device is used for riveting the A plate and the B plate.

[0014] As a preferred technical solution, the nylon opener / closer is a mold accessory that adjusts the friction between the template and the nylon sleeve by locking the conical bolt.

[0015] In one embodiment of this utility model, the nylon opener / closer is fixed to plate B by screws.

[0016] In one embodiment of this utility model, the front mold is further provided with a front mold reset rod. The top end of the front mold reset rod is connected to the front mold ejector plate, and the bottom end of the front mold reset rod is fixed above plate B by a nylon opening and closing device. The front mold reset rod is used to control the front mold reset.

[0023] As a preferred technical solution, the mold has a length of 1160mm, a width of 650mm, and a height of 705mm.

[0024] As a preferred technical solution, the maximum external dimensions of the product are: length 640.4mm, width 136.05mm, and height 950mm.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. The air conditioner upper and lower airflow vane mold structure design provided by this utility model saves space, does not affect the mold strength, leaves sufficient space for the mold water channels, and allows for a uniform and reasonable water channel design, thereby shortening the product production cycle.

[0027] 2. Existing technologies for molds with hooks often involve designing a front mold slider, which occupies too much space, resulting in complex processing and assembly movements. The air conditioner upper and lower airflow deflector mold provided by this utility model is suitable for molds with many hooks in the front mold portion of the product, offering advantages such as simple processing, reliable structure, and reduced risk of mold collisions.

[0028] 3. This utility model integrates the front mold ejector pin assembly into the compact cavity of the upper fixed plate and the A plate, freeing up a large amount of space for water channel layout while ensuring the strength of the mold. It supports a uniformly distributed cooling water channel design, which can improve product cooling efficiency and molding cycle.

[0029] 4. This utility model optimizes the product's dimensions and designs the mold dimensions accordingly. Combined with the rear mold hydraulic cylinder driving the ejector plate, it provides a constant ejection force, perfectly matching the maximum external dimensions of the air conditioner vent plate and solving the industry problem of deformation during the ejection of ultra-thin long parts.
