Description

Technical Field

[0001] The present disclosure relates to the technical field of automobile molds, and in particular to a mold fatigue buffer device and a new energy automobile mold. Background Art

[0002] At present, in new energy vehicle molds, when the molds are not in use, in order to save space, the molds are often stacked. Stacking the molds can easily cause fatigue damage to the mold functional parts such as spring elements. The spring elements face greater pressure when the molds are stacked. The molds themselves have a certain weight. When two molds are stacked together, the spring elements of the bottom mold will be under the gravity pressure from the upper mold. They will be under pressure for a long time, which can easily affect the normal rebound function of the spring elements when the mold is in use, thereby affecting the normal use of the mold.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0028] like Figures 1 to 4 As shown, a mold fatigue buffer device 10 of an embodiment includes an elastic support component 100 and a locking card 200. The elastic support component 100 is used to be arranged on the protective skirt 20 of the mold body 1. The elastic support component 100 includes a fixed support seat 110, an elastic return member 120 and an elastic support seat 130. The fixed support seat 110 is arranged on the protective skirt 20. One end of the elastic return member 120 is connected to the fixed support seat 110, and the other end of the elastic return member 120 is connected to the elastic support seat 130. The elastic return member 120 is used to pop up the elastic support seat 130 when stacking the molds, so that the elastic support seat 130 supports the external mold 2; the locking card 200 is rotatably arranged on the fixed support seat 110, and the locking card 200 is used to rotate a preset angle when the elastic support seat 130 is pressed downward toward the fixed support seat 110, so that the locking card 200 is engaged with the bottom surface of the elastic support seat 130.

[0029] It can be understood that since the fixed support seat 110 is provided on the protective skirt 20, the fixed support seat 110 has a stable support point, and one end of the elastic return member 120 is connected to the fixed support seat 110, and the other end of the elastic return member 120 is connected to the elastic support seat 130. When the mold is in normal use, it is necessary to rotate the locking card 200 to a preset angle to engage with the bottom surface of the elastic support seat 130 to prevent the elastic support seat 130 from rebounding and standing on the fixed support seat 110. When the mold is not in use and needs to be stacked, the locking card 200 is rotated to release the contact with the elastic support seat 130. The elastic support seat 130 bounces up the elastic support seat 130 through the elastic return force of the elastic reset member 120 and stands above the fixed support seat 110, so that the upper surface of the elastic support seat 130 is supported on the external mold 2, avoiding direct contact between the mold body 1 and the external mold 2, and reducing the direct impact of the mold functional parts 30 located on the mold body 1 on the external mold 2, thereby reducing fatigue damage to the mold functional parts 30. At the same time, the mold fatigue buffer device 10 is only supported by the fixed support seat 110 and the elastic support seat 130 to support the external mold 2, which simplifies the structure.

[0030] like Figure 3 and Figure 4 As shown, in one embodiment, the maximum height from the bottom surface of the protective skirt 20 to the mold functional part 30 is less than the maximum height from the bottom surface of the protective skirt 20 to the elastic support seat 130 when it bounces up. In this embodiment, since the mold functional part 30 is located inside the mold body 1, when the external mold 2 needs to be stacked on the mold body 1, the exposed part of the mold functional part 30, such as the spring element, will be subjected to the heavy pressure of the external mold 2 and fatigue damage. The present disclosure sets the maximum height from the bottom surface of the protective skirt 20 to the elastic support seat 130 when it bounces up to be greater than the maximum height from the bottom surface of the protective skirt 20 to the mold functional part 30, so that the mold functional part 30 is located between the mold body 1 and the external mold 2, preventing the external mold 2 from touching the mold functional part 30, reducing fatigue damage to the mold functional part 30, and thus improving the service life of the mold body 1.

[0031] In one embodiment, the elastic return member 120 is an elastic hinge structure. In this embodiment, the elastic hinge structure ensures the elastic hinge connection between the fixed support base 110 and the elastic support base 130, so that the elastic support base 130 can be rotatably supported on the fixed support base 110.

[0032] like Figure 1 and Figure 2As shown, in one embodiment, the elastic return member 120 includes a first hinge 121, a second hinge 122, a connecting shaft 123 and a return spring 124, the first hinge 121 is rotatably connected to the second hinge 122 through the connecting shaft 123, the return spring 124 is sleeved on the connecting shaft 123 and is arranged between the first hinge 121 and the second hinge 122, and the first side of the return spring 124 is connected to one side of the first hinge 121, the second side of the return spring 124 is connected to one side of the second hinge 122, and the first side and the second side of the return spring 124 are located on the same side; the first hinge 121 is detachably connected to the elastic support seat 130, and the second hinge 122 is detachably connected to the fixed support seat 110. In this embodiment, since the first hinge 121 is detachably connected to the elastic support seat 130 and the second hinge 122 is detachably connected to the fixed support seat 110, the elastic support seat 130 is easy to disassemble and assemble, ensuring that the elastic support seat 130, the first hinge 121 and the second hinge 122 can be maintained in time, thereby ensuring safety and reliability during use. Since the two sides of the return spring 124 are respectively connected to one side of the first hinge 121 and one side of the second hinge 122 and the first side and the second side of the return spring 124 are located on the same side, the first hinge 121 and the second hinge 122 can be compressed and automatically reset under the action of the return spring 124, ensuring that the elastic support seat 130 can be elastically supported on the fixed support seat 110.

[0033] like Figure 1 and Figure 3 As shown, in one embodiment, the locking clip 200 is an L-shaped structure, including a locking portion 210 and a rotating portion 220, the locking portion 210 is vertically connected to one end of the rotating portion 220, the connection between the locking portion 210 and the rotating portion 220 is rotatably connected to the fixed support seat 110, and the other end of the rotating portion 220 is used to rotate a preset angle so that the locking portion 210 is engaged with the bottom surface of the elastic support seat 130. In this embodiment, since the elastic support seat 130 stands on the fixed support seat 110 under the elastic return force of the reset spring 124, in order to prevent the elastic support seat 130 from automatically rebounding during normal use of the mold body 1, it is necessary to press the elastic support seat 130 downward toward the side of the fixed support seat 110 where the elastic reset member 120 is provided, and then rotate the rotating part 220 of the locking clamp 200 so that the locking part 210 abuts against the bottom surface of the elastic support seat 130, preventing the elastic support seat 130 from automatically rebounding and standing on the fixed support seat 110, thereby ensuring the normal use of the mold body 1.

[0034] like Figure 2 As shown, in one embodiment, the return spring 124 is a torsion spring structure, which can automatically return to its original position after an external force is applied.

[0035] like Figure 1 and Figure 3 As shown, in one embodiment, there are multiple elastic support assemblies 100, and the multiple elastic support assemblies 100 are evenly arranged on the protective skirt 20. It can be understood that because the multiple elastic support assemblies 100 are evenly arranged on the protective skirt 20, the external mold 2 is stacked on the multiple elastic support seats 130 of the mold body 1, ensuring uniform force when the multiple elastic support seats 130 simultaneously support the external mold 2. In this embodiment, there are four elastic support assemblies 100, and the four elastic support assemblies 100 are respectively arranged at the four corners of the protective skirt 20.

[0036] like Figure 1 and Figure 4 As shown, in one embodiment, the mold fatigue buffer device 10 further includes a receiving buffer block 300. The receiving buffer block 300 is at least partially embedded in the elastic support seat 130, and the protruding portion of the receiving buffer block 300 is used to support the external mold 2. In this embodiment, because the receiving buffer block 300 is at least partially embedded in the elastic support seat 130, the receiving buffer block 300 is firmly fixed in the elastic support seat 130, ensuring that the receiving buffer block 300 plays a buffering and supporting role when the external mold 2 is placed on the elastic support seat 130, avoiding direct contact between the elastic support seat 130 and the external mold 2, thereby improving the service life of the elastic support seat 130.

[0037] In one embodiment, the receiving buffer block 300 is a polyurethane receiving block. Since polyurethane has a shock-absorbing and buffering function, the polyurethane receiving block can reduce the direct impact and wear on the external mold 2 when the elastic support seat 130 abuts against the external mold 2.

[0038] The present disclosure also provides a new energy vehicle mold, comprising the mold fatigue buffer device 10 described in any of the above embodiments.

[0039] Compared with the prior art, the present disclosure has at least the following advantages:

[0040] The mold fatigue buffer device 10 disclosed in the present invention has a fixed support seat 110 provided on the protective skirt 20, so that the fixed support seat 110 has a stable support point, and one end of the elastic reset member 120 is connected to the fixed support seat 110, and the other end of the elastic reset member 120 is connected to the elastic support seat 130. When the mold is in normal use, it is necessary to rotate the locking clamp 200 to a preset angle to engage with the bottom surface of the elastic support seat 130 to prevent the elastic support seat 130 from rebounding and standing on the fixed support seat 110. When the mold is not in use and needs to be stacked, the locking clamp 200 is rotated to release the elastic support seat. 130 is in contact with the elastic support seat 130, and the elastic support seat 130 is bounced up by the elastic return force of the elastic reset member 120 and stands above the fixed support seat 110, so that the upper surface of the elastic support seat 130 is supported on the external mold 2, avoiding direct contact between the mold body 1 and the external mold 2, reducing the direct impact of the mold functional parts 30 located on the mold body 1 on the external mold 2, thereby reducing fatigue damage to the mold functional parts 30, and at the same time, the mold fatigue buffer device 10 is only supported by the fixed support seat 110 and the elastic support seat 130 to support the external mold 2, so that the structure is simplified.

[0041] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
