[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] See also Figures 2 to 11 , the electric control box mold is used to manufacture Figure 1 The electric control box 100 shown has an uneven wall thickness, with some parts having thicker wall thickness and some parts having thinner wall thickness, and has a deep cavity and an inclined surface.

[0032] The electric control box mold comprises a lower mold 10 , a middle mold 20 , an upper mold 30 and a corrugated plate 50 . A cavity 40 is formed between the middle mold 20 and the upper mold 30 . The cavity 40 is used to form the electric control box 100 .

[0033] The lower mold 10 includes a lower mold base 11, a first point cooling structure 12 and an extrusion structure 13. The first point cooling structure 12 and the extrusion structure 13 are installed inside the lower mold base 11. There are multiple first point cooling structures 12, each of which is a vertically arranged cooling pipe, and the end of the cooling pipe corresponds to the position of the wall thickness area of ​​the electric control box 100. The first point cooling structure 12 is used to spot cool the wall thickness area at the bottom of the electric control box 100, which can balance the overall solidification sequence of the product.

[0034] The extrusion structure 13 includes an extrusion drive 130, an extrusion rod 131, and a hydraulic system 132. The extrusion rod 131 is in transmission connection with the extrusion drive 130. The extrusion drive 130 drives the extrusion rod 131 to move in the vertical direction to extrude two deep cavity columns in the thick wall area of ​​the electric control box 100, thereby improving the density of the product and reducing the probability of the generation of shrinkage holes. In this embodiment, the extrusion drive 130 is a hydraulic cylinder, and the hydraulic system 132 is connected to the hydraulic cylinder to supply oil to the hydraulic cylinder.

[0035] The middle mold 20 includes a base 25 and a plurality of sliding structures installed on the base 25. The sliders of the plurality of sliding structures are slidably installed on the base 25. The ends of the plurality of sliders form the side walls of the cavity 40. The tops of the plurality of sliders are provided with runners, so that the cavity 40 can be fed from multiple sides, shortening the material travel and preventing the generation of bubbles.

[0036] Specifically, there are four sliding structures, namely, a first sliding structure 21, a second sliding structure 22, a third sliding structure 23 and a fourth sliding structure 24. The first sliding structure 21 is located at the gate, the second sliding structure 22 and the third sliding structure 23 are arranged opposite to each other and are respectively located on both sides of the gate, and the fourth sliding structure 24 is located on one side of the exhaust channel. The specific structures of the four sliding structures are roughly the same, except that an inclined surface is provided on the side wall of the cavity 40 corresponding to the fourth sliding structure 24, so two sliders are provided on the fourth sliding structure 24.

[0037] Specifically, taking the second sliding structure 22 as an example, the sliding structure is described:

[0038] The second sliding structure 22 includes a first mounting frame 220, a first driving member 221 and a first slider 222. The first driving member 221 is fixed to the first mounting frame 220, the first slider 222 is slidably mounted on the base 25, the first slider 222 is transmission-connected to the first driving member 221, and the first driving member 221 drives the first slider 222 to move. A first runner 2220 is provided on the top of the first slider 222 near the cavity 40, the first runner 2220 is located on the side of the cavity 40, a heating channel 2221 is provided inside the first slider 222 near the cavity 40, the heating channel 2221 heats the first slider 222 through mold temperature oil, so that the thin part of the side wall of the electric control box in the cavity 40 is heated to avoid rapid cooling of the thin part, thereby controlling the overall solidification sequence and avoiding the generation of bubbles.

[0039] The fourth sliding structure 24 includes a second mounting frame 240, a second driving member 241, a second slider 242, a third driving member 243 and a third slider 244. The second driving member 241 is fixed to the second mounting frame 240, the second slider 242 is transmission-connected to the second driving member 241, the third driving member 243 is transmission-connected to the third slider 244, the third slider 244 is slidably mounted on the second slider 242, the second slider 242 is horizontally arranged, the third slider 244 is tilted, and the second slider 242 and the third slider 244 are arranged on the side wall of the electric control box 100 corresponding to the tilt structure.

[0040] The base 25 includes a lower mold core 251, which forms the bottom wall of the cavity 40. Two exhaust passages 2510 are provided at the top of one side of the lower mold core 251. The base 25 is also provided with four slide grooves 250, which correspond to the four side walls of the cavity 40. The slide grooves 250 are used to install the slider.

[0041] The upper mold 30 includes an upper mold core 31 and a second point cooling structure 32. The upper mold core 31 is used to form the top of the cavity 40. There are multiple second point cooling structures 32. Each second point cooling structure 32 is a vertically arranged cooling pipe. The end of the cooling pipe corresponds to the position of the wall thickness area of ​​the electric control box 100. The second point cooling structure 32 is used to spot cool the wall thickness area at the bottom of the electric control box 100, which can balance the overall solidification sequence of the product.

[0042] There are two wave plates 50 , and the two wave plates 50 are connected to the two exhaust passages 2510 respectively. The two wave plates 50 are symmetrically arranged with respect to the cavity 40 .

[0043] When using the electric control box mold, the liquid material enters from the runner, enters the cavity 40 from the runners on the three sides of the cavity 40, and solidifies in the cavity 40. During the solidification process, the ends of the cooling pipes of the first point cooling structure 12 and the second point cooling structure 32 correspond to the positions of the thick wall areas of the electric control box 100. The first point cooling structure 12 performs spot cooling on the thick wall area at the bottom of the electric control box 100, which can balance the overall solidification sequence of the product. The heating channel 2221 heats the thin side wall of the electric control box in the cavity 40 through the mold temperature oil to the slider, avoiding rapid cooling of the thin side wall, thereby controlling the overall solidification sequence and avoiding the generation of bubbles. The extrusion drive 130 drives the extrusion rod 131 to move in the vertical direction, extruding the two deep cavity columns in the thick wall area of ​​the electric control box 100, improving the product density and reducing the probability of shrinkage holes. The wave plate 50 is vacuumed to reduce the gas content in the cavity 40.

[0044] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
