[0029] Example 1:

[0030] The freezer fan cover injection molding mold includes a freezer fan cover injection molding machine body 1, the freezer fan cover injection molding machine body 1 is fixedly connected to the base 5 inside, and a mounting mechanism 3 is provided on one side of the base 5, and the mounting mechanism 3 includes an extension plate 304, a locking rod 305, a support plate 306, an L-shaped plate 307, a limiting groove 309, a storage groove 310, a rack 311, a gear 314, a mounting plate 301, a mounting groove 315 and a reset spring 316. The front of the mounting plate 301 is rotatably connected to the gear 314, and the top and bottom ends of the gear 314 are both meshed with the rack 311. One end of the two racks 311 is fixedly connected to the L-shaped plate 307. The middle part of the front of the two L-shaped plates 307 is provided with a limiting groove 309. The mounting plate 30 The front of 1 is vertically slidably connected to an extension plate 304, a through slot 312 is provided on the front of the extension plate 304, a rack 2 313 is fixedly connected to one side of the inner wall of the through slot 312, the bottom end of the extension plate 304 is fixedly connected to a support plate 306, the top of the support plate 306 is fixedly connected to a plurality of locking rods 305, the front of the mounting plate 301 is placed with the mold body 2, the top of the mounting plate 301 is provided with a mounting slot 315, the inner wall of the mounting slot 315 is slidably connected to the unlocking plate 302, the front of the unlocking plate 302 is fixedly connected to the locking plate 303, the top of the freezer fan cover injection molding machine body 1 is slidably connected to the closing member 6, the back of the mounting plate 301 is fixedly connected to the front of the base 5, and the two L-shaped plates 307 are both slidably connected to the mounting plate 301. The inner walls of the two limiting grooves 309 are slidably connected to the limiting rods 308, and the two limiting rods 308 are fixedly connected to the front of the mounting plate 301. The limiting rods 308 can enhance the sliding stability of the L-shaped plate 307. The bottom of the front of the two L-shaped plates 307 is provided with a storage groove 310, and the storage groove 310 is used to store rack 1 311. The two storage grooves 310 match the sizes of the two racks 1 311. The inner side of rack 2 313 is meshed with the gear 314. The top ends of the multiple locking rods 305 are inserted into the bottom of the mold body 2. The bottom of the mold body 2 is provided with multiple holes. The multiple locking rods 305 are inserted into the inside of the multiple holes. The front of the locking plate 303 passes through the front of the mounting plate 301, and the bottom end of the locking plate 303 fits into At the top of the mold body 2, the locking plate 303 is in the shape of a trapezoid, and its front side has a chamfer to avoid damaging its surface when installing and removing the mold body 2. The back of the unlocking plate 302 is fixedly connected to two return springs 316, and one end of the two return springs 316 is fixedly connected to the inner wall of the installation groove 315. It should be noted that when the refrigerator fan cover injection molding machine body 1 injects the refrigerator fan cover injection molded part, the user starts the closing member 6 to fit the closing member 6 into the mold body 2. The refrigerator fan cover injection molding machine body 1 heats the plastic and sends it into the interior of the mold body 2. The mold body 2 and the closing member 6 form a closed space to ensure that the plastic can fill all parts of the mold body 2. The mold body 2 is then cooled and the plastic inside is cooled and solidified.Thus, the refrigerator fan cover injection molding part is obtained.

[0031] When the user needs to install the mold body 2 during work, the user can place the bottom end of the mold body 2 on the supporting plate 306, and the back of the mold body 2 presses the locking plate 303. After the locking plate 303 is pressed, it enters the inside of the mounting groove 315. The plurality of locking rods 305 on the supporting plate 306 are inserted into the bottom end of the mold body 2. The weight of the mold body 2 drives the supporting plate 306 to descend. The supporting plate 306 drives the extension plate 304 to descend. When the extension plate 304 descends, it moves together with the rack two 313. The rack two 313 drives the gear 314 to rotate. The rotating gear 314 drives the two racks one 311 to move, respectively. The two racks one 311 drive the L-shaped plates 307 to approach each other. The limiting rods 308 are in sliding connection with the limiting grooves 309 in the process of moving the L-shaped plates 307. The limiting rods 308 can limit the L-shaped plates 307. When the inner sides of the two L-shaped plates 307 fit the mold body 2, the two racks one 311 are inserted into the corresponding storage grooves 310. When the mold body 2 no longer presses the locking plate 303, the two return springs 316 push the unlocking plate 302 to move. The unlocking plate 302 drives the locking plate 303 to move, so that the bottom end of the locking plate 303 tightly fits the top end of the mold body 2. Thus, the accurate limiting of the mold body 2 is realized. The whole process does not need to rely on other tools, and the mold body 2 can be quickly and conveniently fixed. When the user needs to replace the mold body 2, the user pushes the unlocking plate 302. The unlocking plate 302 presses the two return springs 316. When the unlocking plate 302 drives the locking plate 303 to enter the inside of the mounting groove 315, the user can pull the mold body 2 to rise, so as to rise the mold body 2. Not only is the time for replacing the mold body 2 reduced, but also the production efficiency is improved. The operation is simple and convenient, and the user is facilitated.

[0033] On the basis of Example 1, a heat dissipation mechanism 4 is provided on the outside of the mold body 2, and the heat dissipation mechanism 4 includes a connecting plate 401, a dustproof net 402, a cooling fan 403, a heat conducting plate 404 and heat dissipation fins 405. The inner sides of the two connecting plates 401 are fixedly connected to multiple cooling fans 403, and the top, bottom and two side walls of the mold body 2 are fixedly connected to the heat conducting plates 404. The heat conducting plates 404 and the heat dissipation fins 405 are all made of metal copper, which is resistant to high temperature and has good thermal conductivity. The side walls of multiple heat conducting plates 404 are fixedly connected to multiple heat dissipation fins 405, and the two connecting plates 401 are fixedly connected to the two side walls of the base 5. The outer sides of the two connecting plates 401 are snap-connected with the dustproof net 402. The dustproof net 402 can reduce the dust accumulation of the cooling fan 403 and affect its heat dissipation effect. It should be noted that the time to start the cooling fan 403 is after the freezer fan cover injection molding machine body 1 is injected, which can help shorten the molding cycle of the freezer fan cover injection molding part.

[0034] When the user starts the freezer fan cover injection molding machine body 1 for injection molding, the heat of injection is transferred to the mold body 2, the mold body 2 transfers the heat to multiple heat conducting plates 404, the multiple heat conducting plates 404 transfer the heat to multiple heat dissipating fins 405, and the multiple heat dissipating fins 405 dissipate the heat into the air. The user can start multiple cooling fans 403, and the multiple cooling fans 403 can speed up the air circulation around the heat dissipating fins 405, which not only helps to shorten the molding cycle of the freezer fan cover injection molding parts, but also helps to maintain the operating temperature of the machine, ensure the stable quality of the freezer fan cover injection molding parts, and also extend the service life of the freezer fan cover injection molding machine body 1.
