Description

Technical Field

[0001] The utility model relates to the technical field of molding devices, and more specifically, to a molding device for automobile molds. Background Art

[0002] The most important component of automobile molds is the cover mold, which is mainly a cold stamping mold. In a broad sense, "automotive molds" are the general term for molds used to manufacture all parts of a car.

[0003] A molding device is usually required when making automobile molds. Molding is performed by injecting molten material into the interior of the mold. When closing the mold, the existing molding device starts injecting material by moving the upper mold downward and closing it with the lower mold. However, the lower mold is usually fixed on a table. The upper mold and the lower mold are in hard contact, which causes collision and extrusion on the top of the lower mold when in contact. Over time, the contact surface between the upper mold and the lower mold will be deformed, thereby affecting the sealing between the upper and lower molds. At the same time, the appearance of the molded automobile mold will change, affecting the quality of the product. Therefore, it needs to be improved. Utility Model Content

[0016] 1. The utility model provides a lower mold body, a moving block, a spring and a hinged rod. When the upper mold body moves downward and contacts the lower mold body, the lower mold body will be pushed downward, so that the hinged rod can push the two moving blocks to move in opposite directions, thereby compressing the spring, so that the spring can push the moving block outward under the action of elastic recovery, so that the hinged rod can push the lower mold body upward, and the contact between the upper mold body and the lower mold body can be changed from hard contact to soft contact, thereby avoiding the situation where the upper mold body directly presses the lower mold body downward, causing the contact surface of the upper mold body and the lower mold body to be deformed.

[0025] like Figures 1 to 5 As shown, the utility model provides a molding device for automobile molds, comprising:

[0026] Base 1, a fixing frame 2 is fixedly installed on the rear side of the top of the base 1, a motor 3 is fixedly installed on the top of the fixing frame 2, a threaded rod 4 is fixedly connected to the other end of the output shaft of the motor 3, the bottom end of the threaded rod 4 passes through the fixing frame 2 and extends to the inside of the fixing frame 2 and is movably sleeved with the inner wall of the fixing frame 2, a lifting block 5 is threadedly sleeved on the outer surface of the threaded rod 4, the outer surface of the lifting block 5 is movably connected to the inner surface of the fixing frame 2, an upper mold body 6 is fixedly connected to the front of the lifting block 5, an injection tube 7 is fixedly sleeved inside the top of the upper mold body 6, a limiting plate 8 is fixedly installed on the top of the base 1, and a lower mold body 9 is movably connected between the limiting plates 8;

[0027] A buffer mechanism, the buffer mechanism is arranged inside the base 1;

[0028] Among them, the buffer mechanism includes a sealed cavity 10, which is opened on the left and right sides of the base 1. A moving block 11 is movably sleeved inside the sealed cavity 10. A spring 12 is fixedly connected to the outside of the moving block 11. The other end of the spring 12 is fixedly connected to the inner surface of the sealed cavity 10. A hinged rod 13 is hinged on the inside of the moving block 11. The top of the hinged rod 13 is hinged to the bottom of the lower mold body 9. The spring 12 will drive the moving block 11 to reset under the action of elastic recovery.

[0029] When the operator can start the motor 3 to rotate the threaded rod 4, the lifting block 5 and the upper mold body 6 can be driven to move downward, so that the upper mold body 6 can move downward to contact the lower mold body 9, so that the upper mold body 6 and the lower mold body 9 are closed. When the upper mold body 6 contacts the top of the lower mold body 9, it will push the lower mold body 9 downward, so that the lower mold body 9 pushes the two moving blocks 11 to move oppositely inside the sealing cavity 10 through the hinge rod 13, thereby compressing the spring 12.

[0030] The left and right sides of the lower mold body 9 are both provided with cavities 14 , and the left and right sides of the lower mold body 9 are both fixedly connected with connecting hoses 15 , and the bottom ends of the connecting hoses 15 are fixedly connected to the top of the base 1 .

[0031] When the two moving blocks 11 move in opposite directions, the air in the sealed cavity 10 is squeezed into the connecting hose 15 and then enters the cavity 14 through the connecting hose 15 .

[0032] The left and right sides of the top of the lower mold body 9 are both provided with first through holes 16 , and the left and right sides of the top of the lower mold body 9 are respectively provided with second through holes 17 located at the front and rear sides of the first through holes 16 .

[0033] By providing the first through hole 16 and the second through hole 17 , the first through hole 16 and the second through hole 17 can generate suction force under negative pressure, so that the upper mold body 6 and the lower mold body 9 can fit more closely.

[0034] A disc 18 is movably sleeved inside the cavity 14 , and a limiting ring 19 located above the disc 18 is fixedly sleeved inside the cavity 14 .

[0035] By providing the limiting ring 19 , the limiting ring 19 can limit the disk 18 .

[0036] Among them, the top of the disk 18 is fixedly connected to a vertical rod 20, the top of the vertical rod 20 passes through the cavity 14 and extends to the inside of the first through hole 16, the front and rear sides of the outer surface of the vertical rod 20 are fixedly connected to connecting plates 21, the other end of the connecting plate 21 passes through the first through hole 16 and extends to the inside of the second through hole 17, the top of the connecting plate 21 and the top of the vertical rod 20 are fixedly installed with piston plates 22, and the outer surface of the piston plate 22 is movably connected to the inner surface of the second through hole 17 and the inner surface of the first through hole 16 respectively.

[0037] When the disc 18 moves downward, it will drive the vertical rod 20 and the connecting plate 21 to move downward, thereby enabling the piston plate 22 to move downward.

[0038] A first air outlet 23 located outside the cavity 14 is formed inside the lower mold body 9 , and a second air outlet 24 located outside the first through hole 16 is formed inside the lower mold body 9 .

[0039] By providing the first air outlet 23 , the disc 18 can squeeze the air out of the cavity 14 through the first air outlet 23 when it moves downward.

[0040] The tops of the left and right sides of the lower mold body 9 are both provided with air inlet holes 25 located outside the first through hole 16 , and the tops of the left and right sides of the lower mold body 9 are both fixedly provided with valves 26 located outside the air inlet holes 25 .

[0041] By starting the valve 26 , external air can enter into the first through hole 16 , so that the adsorption effect of the first through hole 16 and the second through hole 17 on the upper mold body 6 can be released.

[0042] The working principle and use process of this utility model:

[0043] First, the operator starts the motor 3 so that the threaded rod 4 drives the lifting block 5 and the upper mold body 6 to move downward. When the upper mold body 6 moves downward and contacts the top of the lower mold body 9, it will push the lower mold body 9 to move downward, so that the hinge rod 13 can push the two moving blocks 11 to move away from each other, thereby compressing the spring 12, so that the spring 12 can push the moving block 11 outward under the action of elastic recovery, so that the hinge rod 13 can push the lower mold body 9 upward, so that when the upper mold body 6 and the lower mold body 9 are in contact, the impact force can be buffered, and the contact between the upper mold body 6 and the lower mold body 9 is changed from hard contact to soft contact, thereby avoiding the upper mold body 6 directly squeezing the lower mold body 9 downward, causing the contact surface of the upper mold body 6 and the lower mold body 9 to be deformed, thereby improving the service life of the upper mold body 6 and the lower mold body 9.

[0044] When the two moving blocks 11 move in opposite directions, the moving blocks 11 will squeeze the air inside the sealed cavity 10, so that the air inside the sealed cavity 10 enters the cavity 14 through the connecting hose 15, so that the air can push the disc 18 to move downward, and then the disc 18 drives the vertical rod 20 and the connecting plate 21 to move downward, so that the piston plate 22 can move downward. At this time, the bottom of the upper mold body 6 is in contact with the top of the lower mold body 9, so that the first through hole 16 and the second through hole 17 can generate negative pressure, and then the first through hole 16 and the second through hole 17 can generate suction on the upper mold body 6, so that the upper mold body 6 and the lower mold body 9 can fit more closely, thereby improving the sealing effect between the upper mold body 6 and the lower mold body 9. When the injection molding is completed, the valve 26 can be started to release the sealing effect of the valve 26 on the air inlet 25. At this time, the outside air will enter the first through hole 16 through the valve 26 and the air inlet 25, so that the air pressure inside the first through hole 16 is consistent with the outside, and the adsorption effect on the upper mold body 6 can be released. At this time, the operator can start the motor 3 to reset the upper mold body 6. When the upper mold body 6 rises, the spring 12 will push the moving block 11 inward under the action of elastic recovery, so that the air inside the cavity 14 can be sucked into the inside of the sealing cavity 10 through the connecting hose 15, thereby reducing the air pressure inside the cavity 14 and above the disc 18, so that the disc 18 rises, so that the piston plate 22 can be reset.
