Description

A type of automobile mold Technical Field

[0001] This invention belongs to the field of mold technology, and specifically relates to an automobile mold. Background Technology

[0002] As one of the main methods for manufacturing automotive plastic parts, injection molding offers many advantages, including low mold manufacturing costs, short design processes, and the ability to mass-produce parts in a short period. After part production, the mold typically needs to be cleaned and de-adhesive removed for continued use. Traditional cleaning methods usually involve using chemical solvents for chemical de-adhesive removal, which can easily pollute the air and water, posing a threat to human health and the environment. While physical methods can be used for de-adhesive removal, the uneven surface of the mold makes this difficult after production. This is especially true when using molds to produce textured parts, where physical methods are often ineffective. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an automobile mold, the beneficial effect of which is that the present invention can use physical methods to remove glue from the inner surface.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] An automobile mold includes a lower mold and an upper mold, both of which are equipped with a pushing mechanism and a diaphragm fixedly connected inside both the lower mold and the upper mold.

[0006] Both of the aforementioned pushing mechanisms include a pusher base plate, and multiple pusher rods are installed on the upper side of both pusher base plates, with the upper ends of the multiple pusher rods being fixedly connected to the diaphragm.

[0007] Each of the aforementioned push rods has a spring fixedly connected to its lower end, and the other ends of the springs are fixedly connected to the push rod base plate.

[0008] A pusher block is fixed to the upper side of the pusher base plate, and the upper side of the pusher block is consistent with the texture shape of the inner surface of the corresponding lower mold or upper mold.

[0009] The lower mold includes a lower housing, a push-down prism is fixedly connected inside the lower housing, a diaphragm is fixedly connected to the upper side of the push-down prism, and a downward groove corresponding to the pushing mechanism is opened inside the push-down prism.

[0010] The upper mold includes an upper housing, an upper push prism mold fixedly connected inside the upper housing, a diaphragm fixedly connected to the lower side of the upper push prism mold, and an upper sliding groove corresponding to the pushing mechanism opened inside the upper push prism mold.

[0011] Two adjusting studs are fixedly connected to the push-edge base plate, and the lower ends of the two adjusting studs are rotatably connected to the corresponding upper or lower sleeve.

[0012] Each of the aforementioned push rods has two push stop blocks fixedly connected to it, and the upper and lower sliding grooves are each provided with sliding grooves corresponding to the push stop blocks.

[0013] The diaphragm is made of a high-toughness, heat-resistant material.

[0014] The upper side of each of the aforementioned adjusting studs is lower than the upper side of the lower push die or the lower side of the upper push die. Attached Figure Description

[0025] Figure 10 is a schematic diagram of the push rod structure. Detailed Implementation

[0026] As shown in Figure 1:

[0027] An automobile mold includes a lower mold 100 and an upper mold 200. A pushing mechanism 300 is installed inside both the lower mold 100 and the upper mold 200, and a diaphragm 400 is bonded inside both the lower mold 100 and the upper mold 200.

[0028] When the mold is in normal use, the upper mold 200 is snapped onto the lower mold 100, so that a mold cavity is formed between the upper mold 200 and the lower mold 100. Then, injection molding material can be poured into the mold cavity to produce injection molded parts. Then, the workers can open the upper mold 200, take out the injection molded parts, and then perform basic cleaning of the interior of the upper mold 200 and the lower mold 100, so that the injection molding production of parts can continue.

[0029] Since both the upper mold 200 and the lower mold 100 are equipped with a pushing mechanism 300, when it is necessary to injection mold parts with textured surfaces, the operator can manually adjust the pushing mechanism 300 to push the pushing mechanism 300 towards the inner surface of the upper mold 200 or the lower mold 100, so that corresponding raised or recessed textures are generated inside the mold cavity, thereby producing parts with textured surfaces. At the same time, since both the lower mold 100 and the upper mold 200 are bonded with a diaphragm 400, the diaphragm 400 can shield the inner surfaces of the upper mold 200 and the lower mold 100 and the upper part of the pushing mechanism 300, thereby ensuring the smoothness and fluidity of the surface of the injection molded parts. This can prevent the injection material from seeping through the gaps of the pushing mechanism 300 or from sticking and fixing the pushing mechanism 300 during the injection process, which would prevent the injection material from being removed from the mold cavity.

[0030] When it is necessary to clean the inside of the textured mold cavity, the operator can readjust the pushing mechanism 300 to push it in the opposite direction to the inner surface of the upper mold 200 and the lower mold 100, thereby smoothing out the protrusions or depressions inside the mold cavity. At this time, the diaphragm 300 can return to its original shape under its own elasticity, thus making the inside of the mold cavity smooth. This allows for easy removal of adhesive from the inner surface of the mold using physical methods, avoiding the pollution caused by using chemical methods to remove adhesive from the inner surface of the mold.

[0031] As shown in Figure 8:

[0032] Both of the aforementioned pushing mechanisms 300 include a pushing base plate 310, and multiple pushing rods 320 are installed on the upper side of both pushing base plates 310. The upper ends of the multiple pushing rods 320 are bonded to the diaphragm 400.

[0033] When it is necessary to injection mold textured parts, the operator can adjust the push plate 310 to raise it, thereby pushing the push rod 320 to rise. This pushes the upper end of the push rod 320 out of the inner surface of the upper mold 200 or lower mold 100, thus highlighting the corresponding texture on the diaphragm 400. This allows the corresponding texture to be raised or recessed on the inner surface of the upper mold 200 or lower mold 100, enabling the injection molding production of textured parts.

[0034] Meanwhile, since the upper ends of multiple push rods 320 are all bonded to the diaphragm 400, it can be ensured that when the operator adjusts the push base plate 310, the part of the diaphragm 400 bonded to the upper end of the push rod 320 can move along with the push rod 320. This can prevent the diaphragm 400 from maintaining its original shape due to its own elasticity, thus ensuring that the surface texture of the injection-molded finished parts is clear and complete.

[0035] As shown in Figure 10:

[0036] Each of the multiple push rods 320 has a section of a spring 330 fixedly connected to its lower end, and the other end of each of the multiple springs 330 is fixedly connected to the push rod base plate 310.

[0037] When the push rod 320 is pushed upward by the push rod base plate 310, the spring 330 is compressed, so that when the surface texture of the finished part to be produced is of different depths, the upward-moving push rod 320 can move different distances until the upper end of the push rod 320 reaches the predetermined position. This can prevent the push rod 320 from being pushed too far in areas with shallow textures, which would cause the surface texture of the finished part to not meet the requirements.

[0038] Meanwhile, the elastic force generated by the compression of spring 330 can prevent the pressure of the push rod 320 from dropping during the injection molding process, thereby further ensuring that the surface texture of the finished parts produced by injection molding is clear and complete.

[0039] Meanwhile, when the push rod 320 is pushed downward by the push rod base plate 310, the spring 330 can be stretched under force, so that when the surface texture of the finished part to be produced has different depths, the downward-moving push rod 320 can move different distances until the upper end of the push rod 320 is flush with the inner surface of the mold, so that the diaphragm 400 can be restored to smoothness, and thus the cleaning work of the inner surface of the mold can be carried out smoothly.

[0040] As shown in Figure 9:

[0041] The upper side of the pusher plate 310 is welded with a pusher block 311. The upper side of the pusher block 311 is consistent with the texture shape of the inner surface of the corresponding lower mold 100 or upper mold 200. This ensures that when the worker pushes the pusher plate 310 upward, the pusher plate 310 can push the pusher rod 320 to form the required texture shape. At the same time, the distance and direction of the pusher rod 320 can be consistent with the inner surface of the corresponding lower mold 100 or upper mold 200. This ensures that the individual pusher rod 320 is perpendicular to the inner surface of the corresponding lower mold 100 or upper mold 200, thereby avoiding the phenomenon that the texture generated by the pusher plate 310 is different from the actual texture generated.

[0042] As shown in Figures 2, 5, and 6:

[0043] The lower mold 100 includes a lower housing 110, a lower push prism mold 120 welded inside the lower housing 110, a diaphragm 400 bonded to the upper side of the lower push prism mold 120, and a lower push prism mold 121 corresponding to the pushing mechanism 300 is opened inside the lower push prism mold 120.

[0044] The upper mold 200 includes an upper shell 210, an upper push prism mold 220 welded inside the upper shell 210, a diaphragm 400 bonded to the lower side of the upper push prism mold 220, and an upper sliding groove corresponding to the pushing mechanism 300 opened inside the upper push prism mold 220.

[0045] When assembling the lower mold 100 or the upper mold 200, the operator can install the pushing mechanism 300 on the lower pushing prism mold 120 or the upper pushing prism mold 220, so that the pushing rod 320 on the pushing mechanism 300 can be inserted into the lower sliding groove 121 or the upper sliding groove. This allows the pushing rod 320 to move within the lower sliding groove 121 or the upper sliding groove, thereby preventing the pushing rod 320 from shaking during sliding and thus preventing the pushing rod 320 from breaking during pushing.

[0046] Further:

[0047] The push-edge base plate 310 is connected to two adjusting studs 340 by threads. The lower ends of the two adjusting studs 340 are rotatably connected to the corresponding upper sleeve 210 or lower sleeve 110. When the operator needs to adjust the height of the push-edge base plate 310, the position of the push-edge base plate 310 on the adjusting studs 340 can be adjusted by rotating the adjusting studs 340, so that the height of the push-edge base plate 310 can be adjusted smoothly without causing the push-edge base plate 310 to shake during the height adjustment process.

[0048] Meanwhile, by rotating the adjusting stud 340 to adjust the height of the pusher plate 310, it is possible to prevent the pusher plate 310 from continuing to slide after the height is adjusted. This prevents the height of the pusher plate 310 from changing during the production process, thus ensuring that the texture generated on the inner surface of the mold does not fade or disappear, and further ensuring that the texture on the surface of the finished part is complete and clear.

[0049] As shown in Figure 10:

[0050] Each of the aforementioned push rods 320 has two push stop blocks 321 welded on it. The upper sliding groove and the lower sliding groove 121 are both provided with sliding grooves corresponding to the push stop blocks 321. Thus, when the operator adjusts the height of the push base plate 310 to make the push rod 320 protrude or recede, the sliding grooves can block the push stop blocks 321, thereby preventing the corresponding push rod 320 from continuing to move. This ensures that the corresponding push rod 320 can only stay at the predetermined height, while the other push rods 320 can continue to move with the height adjustment of the push base plate 310. This ensures that the push rods 320 can form the required textures of different heights and depths on the inner surface of the mold, thereby producing finished parts with textures of different heights, depths and shapes.

[0051] As shown in Figures 2 and 6:

[0052] The diaphragm 400 is made of a high-toughness and heat-resistant material, which can prevent the diaphragm 400 from deforming during the injection molding process and extend the service life of the diaphragm 400 during repeated pushing and driving by the push rod 320.

[0053] As shown in Figures 3 and 7:

[0054] The upper sides of all the aforementioned adjusting studs 340 are lower than the upper side of the lower push-down prism 120 or the lower side of the upper push-down prism 220, thereby ensuring that during mold use and the mold closing process of the upper mold 200 and the lower mold 100, the adjusting studs 340 at the corresponding positions will not interfere with each other, thus avoiding the phenomenon that the adjusting studs 340 cannot be closed for production due to interference between them.
