DETAILED DESCRIPTION

[0025] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] See also Figure 1 , Figure 3 and Figure 6 The present embodiment provides a stamping die for automobile bushing production with a quick demoulding structure, including a base 1, a molding mechanism 3 and an adjustment mechanism 2. The molding mechanism 3 includes two molding dies 31. The two molding dies 31 have molding cavities on opposite side walls. The molding cavities of the two molding dies 31 serve as automobile bushing molding places. When the two molding dies 31 are close together and attached together, automobile bushing molding operations can be performed. After the two molding dies 31 are separated, demoulding operations can be performed.

[0028] An inverted T-shaped slide groove 11 is provided on the base 1, and an inverted T-shaped slider 32 is fixedly provided at the bottom end of the forming mold 31, which is slidably engaged with the inside of the inverted T-shaped slide groove 11. The inverted T-shaped sliders 32 at the bottom ends of the two forming molds 31 are slid along the inverted T-shaped slide groove 11 of the base 1 toward the side where they are close to each other, so that the two forming molds 31 can be quickly brought together and fitted together. The inverted T-shaped sliders 32 at the bottom ends of the two forming molds 31 are slid along the inverted T-shaped slide groove 11 of the base 1 toward the side where they are away from each other, so that the two forming molds 31 can be quickly separated.

[0029] By opening a plurality of plug holes 313 connected to the inside of the molding cavity on the side walls of the two molding dies 31 that are away from each other, the molding mechanism 3 includes two support plates 33, and the two support plates 33 are respectively located on the side walls of the two molding dies 31 that are away from each other, and a plurality of plug rods 34 are fixedly provided on the opposite side walls of the two support plates 33, and a plurality of plug rods 34 on the side wall of the same support plate 33 are slidably plugged into the plug holes 313. When the two molding dies 31 are brought together to perform molding operations on the automobile bushing, the plug rod 34 on the side wall of the support plate 33 is horizontally slid and fed along the inside of the plug hole 313 until the end of the plug rod 34 blocks the opening of the plug hole 313 close to the molding cavity, and the end of the plug rod 34 is flush with the inner wall of the molding cavity, so that the inside of the molding cavity of the molding die 31 is smooth, and the precise molding operation of the automobile bushing is not affected.

[0030] Since the formed bushing has a high degree of fit with the inner wall of the mold, it is not convenient to quickly demold it. Before the two molding molds 31 are separated and demolded, the two support plates 33 are adjusted to the side away from each other, so that the plug-in rod 34 on the side wall of the support plate 33 slides horizontally in the opposite direction along the inside of the plug-in hole 313. After the plug-in rod 34 is separated from the plug-in hole 313, the outside air can enter the molding cavity through the plug-in hole 313, thereby relieving the pressure in the molding cavity, which is helpful to separate the automobile bushing from the inner wall of the molding cavity and avoid excessive pressure inside the molding cavity during the molding process of the automobile bushing, which causes the automobile bushing to be adsorbed to the inside of the molding cavity and is difficult to separate.

[0031] Then, the two forming dies 31 are separated again to realize a rapid demoulding operation, thereby reducing the defective rate of the finished automobile bushing.

[0032] In order to quickly separate the two support plates 33, the adjustment mechanism 2 includes an L-shaped bracket 21, a rectangular notch is provided at the top of the L-shaped bracket 21, and a top block 22 is horizontally provided inside the rectangular notch, rectangular blocks 211 are fixedly provided on both side walls inside the rectangular notch, rectangular slide grooves are provided on both side walls of the top block 22, and the rectangular blocks 211 are slidably engaged with the inside of the rectangular slide grooves, a hinged notch is provided at the end of the top block 22, and two hinged rods 25 are symmetrically hinged inside the hinged notch, and the ends of the two hinged rods 25 are hinged to the side walls of the two support plates 33 respectively, and the rectangular slide groove of the top block 22 is horizontally slid along the outer wall of the rectangular block 211 of the L-shaped bracket 21 to the side close to the base 1, and the two support plates 33 can be lifted to the side away from each other through the linkage of the hinged rod 25, which helps to achieve a quick pressure relief operation.

[0033] A handle is fixedly provided on one end of the top block 22 away from the hinge notch, so that the top block 22 can be pulled to adjust its position horizontally.

[0034] Embodiment 2

[0035] See also Figure 1-4 , further improvements were made on the basis of Example 1:

[0036] In order to improve the efficiency during demoulding, two support rods 26 are fixedly provided at the top of the L-shaped bracket 21, a pin is rotatably provided between the tops of the two support rods 26, and a lever 27 is fixedly adjusted on the outer wall of the pin, a knocking block 28 is fixedly provided at the end of the lever 27, a docking block 24 is fixedly provided at the upper end of the top block 22 close to the base 1, and an inclined surface is provided on the docking block 24. The knocking block 28 is rotated and lifted around the pin and then released. The knocking block 28 is linked by the lever 27 and automatically swings down around the pin, so as to knock the inclined surface of the docking block 24 on the top block 22, and the top block 22 can be quickly lifted to the side close to the molding mold 31, and the two support plates 33 can be instantly lifted to the side away from each other through the hinged rod 25, thereby improving the efficiency of the plug rod 34 to disengage from the plug hole 313.

[0037] The upper ends of the two molding dies 31 are fixed with a liquid storage cylinder 36, the side wall of the molding die 31 is provided with a liquid storage cavity 312 connected to the inside of each plug hole 313, and the top of the molding die 31 is provided with a liquid guide hole connected to the inside of the liquid storage cylinder 36, the inside of the liquid storage cylinder 36 is slidably plugged with an inverted T-shaped push rod 38, the upper end opening of the liquid storage cylinder 36 is covered with a sealing cap 37, and the sealing cap 37 is provided with a matching hole slidably plugged with the inverted T-shaped push rod 38. The release agent is filled into the liquid storage cylinder 36, and then the inverted T-shaped push rod 38 is pressed down, so that the release agent in the liquid storage cylinder 36 can be squeezed into the liquid storage cavity 312 for temporary storage. When the end of the plug rod 34 is detached from the plug hole 313 close to the opening on one side of the molding cavity, it is also necessary to ensure that the plug rod 34 does not detach from the plug hole 313, so that the release agent can be immersed in the molding cavity, which is helpful to separate the molded automobile bushing from the inner wall of the molding cavity.

[0038] When the two molding dies 31 are separated, the molded automobile bushing can be quickly separated from the inner wall of the molding cavity of the molding die 31, thereby realizing a rapid demoulding operation and reducing the defective rate of the finished automobile bushing.

[0039] The outer wall of the plug rod 34 is sleeved with two symmetrically distributed conical sealing disks 314. A conical sealing disk 314 close to the molding cavity of the molding mold 31 is fixedly sleeved with the outer wall of the plug rod 34 and can abut against the opening of the plug hole 313 on one side close to the molding cavity. A conical sealing disk 314 away from the molding cavity of the molding mold 31 is slidably sleeved with the outer wall of the plug rod 34 and can abut against the opening of the plug hole 313 away from the molding cavity. When the plug rod 34 is separated from the opening of the plug hole 313 close to the molding cavity, the conical sealing disk 314 can abut against the opening of the plug hole 313 away from the molding cavity, thereby preventing the plug rod 34 from being separated from the plug hole 313 and also preventing the release agent from overflowing and wasting.

[0040] In order to achieve simultaneous pressure relief and immersion of the release agent into the molding cavity, a crossbeam 39 is fixedly provided on the side wall of the liquid storage cylinder 36, and an inverted L-shaped support rod 310 is fixedly provided at the end of the crossbeam 39. An inverted L-shaped lever 311 is hinged at the top of the inverted L-shaped support rod 310. One end of the inverted L-shaped lever 311 extends to the top of the inverted T-shaped push rod 38, and the other end is located at the upper end of the crossbeam 39. A connecting plate 35 is fixedly provided at the upper end of the support plate 33. A docking hole that is slidably plugged with the crossbeam 39 is opened on the side wall of the connecting plate 35. The support plate 33 moves away from the molding mold 31. When the position is adjusted by sliding on one side, the plug rod 34 disengages from the opening of the plug hole 313 close to the molding cavity, but does not completely disengage from the plug hole 313. At the same time, the connecting plate 35 can slide horizontally along the outer wall of the cross beam 39, and can flip the inverted L-shaped lever 311 around the hinge of the inverted L-shaped support rod 310, and can press the inverted T-shaped push rod 38 down along the inner wall of the liquid storage cylinder 36, and can squeeze the release agent inside the liquid storage cylinder 36 and the liquid storage cavity 312 into the molding cavity, so as to realize the simultaneous pressure relief and immersion of the release agent, thereby improving the demolding efficiency of the automobile bushing.

[0041] Embodiment 3

[0042] See also Figure 1 and Figure 5 , further improvements were made on the basis of Example 2:

[0043] A threaded rod 29 is fixed on the outer wall of the knocking block 28, and a plurality of counterweight plates 210 are rotatably sleeved on the threaded rod 29 through an external thread. According to the knocking force requirement of the knocking block 28, a plurality of counterweight plates 210 are sleeved on the outer wall of the threaded rod 29, so that the force of the knocking block 28 when swinging down can meet the requirement of quickly lifting the top block 22 to the side close to the molding mold 31.

[0044] In order to facilitate the repeated lifting operation of the ejector block 22, a guide rod 23 is fixed between the side walls on both sides of the rectangular slide groove. The guide rod 23 is slidably plugged into the rectangular block 211, and the outer wall of the guide rod 23 is sleeved with a first spring that can lift the ejector block 22 to the side away from the forming mold 31 in real time. The elastic force of the first spring can lift the ejector block 22 to the side away from the forming mold 31 in real time, thereby leaving a lifting space, so that when the knocking block 28 rotates downward, there is enough space to meet the requirement of lifting the ejector block 22 to the side close to the forming mold 31.

[0045] The outer wall of the plug-in rod 34 is slidably sleeved with a second spring 315 located between two conical sealing disks 314. By utilizing the elastic force of the second spring 315, the conical sealing disk 314 slidably sleeved on the outer wall of the plug-in rod 34 can be pressed against the opening of the plug-in hole 313 away from the molding cavity in real time, thereby avoiding the release agent overflowing and causing waste of the release agent.
