[0002] The auxiliary instrument panel is usually designed with a screw-connected fixing structure with other vehicle body parts at the front end, and is covered with an external cover. At the same time, in order to enhance the installation and support structure in the middle position of the auxiliary instrument panel, an inverted structure is also provided in the middle position on the inside of the auxiliary instrument panel to snap into place with surrounding parts.

[0003] The existing molds for making auxiliary instrument panels usually adopt a hydraulic cylinder core pulling structure, for example, the core inside the undercut (snapping structure) is first driven out by the hydraulic cylinder, and then the subsequent dynamic mold opening action is performed. However, the use of this structural design not only increases the hydraulic cylinder-driven mold opening action and increases the molding cycle time, but also affects the strength of the dynamic mold due to the large clearance of the hydraulic cylinder, reduces the demoulding quality and efficiency, and cannot meet the mold development and design requirements. Utility Model Content

[0004] In view of this, the utility model aims to provide a demoulding mechanism for a sub-instrument panel, which has a better demoulding effect.

[0007] The first slider slides along a first preset direction, the second slider slides along a second preset direction, and the second slider has a molding protrusion extending into the inner side of the auxiliary instrument panel to form an undercut on the inner side wall of the first side panel;

[0008] The linkage mechanism includes a first driving block arranged on the first slider, and a sliding groove arranged on the second slider, the first driving block is slidably arranged in the sliding groove, and when the first slider slides away from the first side plate, the first driving block can drive the second slider to slide along the second preset direction through the sliding groove to disengage the undercut.

[0009] Furthermore, a positioning block for sliding the second sliding block is provided on the first sliding block, and the first driving block is provided on the positioning block.

[0010] Furthermore, the slide groove is arranged obliquely relative to the first preset direction, and the inclination angle is not greater than 23°.

[0011] Furthermore, the second sliding block is provided with a sliding surface parallel to the sliding groove, and the positioning block is provided with a sliding matching surface slidably matched with the sliding surface.

[0013] Furthermore, it also includes a third slider for abutting against the outer side wall of the second side panel in the auxiliary instrument panel, the third slider slides along the first preset direction, and the third slider and the first slider are arranged correspondingly.

[0014] Furthermore, the third slider is provided with a second driving block, and the second driving block has an abutting portion abutting against the inner wall of the second side panel; when the third slider slides away from the second side panel, the second driving block can pull the second side panel through the abutting portion to flip and demold the second side panel back to the first side panel.

[0015] Furthermore, a limiting mechanism is provided between the second driving block and the third slider, and the limiting mechanism is used to limit the second driving block from moving away from the second side plate along with the third slider within a preset distance when the second slider is disengaged from the undercut.

[0019] In addition, the setting of the positioning block is not only conducive to the sliding setting of the second slider, but also conducive to arranging the molded protrusion on the second slider on the inner side of the first side plate.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] Embodiment 1

[0039] The present embodiment relates to a demoulding mechanism for a sub-instrument panel, which can eliminate the method of using a cylinder drive to perform the demoulding action of the undercut 10, making the structure simpler, reducing the cost of mold design and development, and also shortening the molding cycle time of the product and ensuring the demoulding quality.

[0040] In terms of overall structure, Figures 1 to 3 As shown, the demolding mechanism of the auxiliary instrument panel in this embodiment includes a first slider 2 for abutting against the outer wall of the first side panel 11 on the auxiliary instrument panel 1, a second slider 3 arranged on the first slider 2, and a linkage mechanism arranged between the first slider 2 and the second slider 3.

[0041] The first slider 2 slides along a first preset direction, the second slider 3 slides along a second preset direction, and the second slider 3 has a molding protrusion extending into the inner side of the auxiliary instrument panel 1 to form an undercut 10 on the inner wall of the first side panel 11 .

[0042] In addition, the linkage mechanism includes a first driving block 41 arranged on the first slider 2, and a sliding groove 31 arranged on the second slider 3. The first driving block 41 is slidably arranged in the sliding groove 31, and when the first slider 2 slides away from the first side plate 11, the first driving block 41 can drive the second slider 3 to slide along the second preset direction through the sliding groove 31 to disengage the undercut 10.

[0043] It is worth mentioning that the first preset direction of this embodiment is Figure 1 The left and right directions of the state shown in the figure, the second preset direction of this embodiment is Figure 1 At the same time, it can be understood that when the first slider 2 of this embodiment slides away from the first side plate 11 to the right along the first preset direction, the second slider 3 is driven to slide downward along the second preset direction through the first driving block 41 and the slide groove 31 to disengage the undercut 10, thereby realizing the demoulding of the undercut 10.

[0044] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, Figure 1 As shown, a positioning block 4 for sliding the second slider 3 is disposed on the first slider 2 , and a first driving block 41 is disposed on the positioning block 4 .

[0045] The arrangement of the positioning block 4 is not only conducive to the matching arrangement of the first driving block 41 and the slide groove 31 to realize the sliding arrangement of the second slider 3 , but also conducive to arranging the molded protrusion on the second slider 3 on the inner side of the first side plate 11 .

[0046] Furthermore, in this embodiment, as a preferred implementation form, the slide groove 31 is arranged at an inclination relative to the first preset direction, and the inclination angle is not greater than 23°, so that the first driving block 41 has a sufficient driving distance under the drive of the first slider 2, so that the second slider 3 can be disengaged from the undercut 10.

[0047] In specific implementation, the inclination angle of the slide groove 31 of this embodiment relative to the first preset direction can be preferably set to 20° or 21° to ensure that the first driving block 41 has a sufficient driving distance driven by the first slider 2 and allows the second slider 3 to disengage from the undercut 10 in a shorter time.

[0048] In addition, in this embodiment, as a preferred implementation form, combined with Figure 1 and Figure 3As shown, the second slider 3 is provided with a sliding surface parallel to the slide groove 31, and the positioning block 4 is provided with a sliding matching surface 42 that is slidably matched with the sliding surface. The matching arrangement of the sliding surface and the sliding matching surface 42 is conducive to improving the sliding stability of the second slider 3.

[0049] At the same time, in this embodiment, as a preferred implementation form, Figure 3 As shown, the cross-sections of the slide groove 31 and the first driving block 41 are both "T"-shaped, which can make the cooperation between the slide groove 31 and the first driving block 41 have a limiting effect to prevent the second slider 3 from shaking relative to the positioning block 4 during the sliding process.

[0050] Of course, it is worth mentioning that the cross-sections of the slide groove 31 and the first driving block 41 of this embodiment are both "T"-shaped, which, combined with the sliding surface and the sliding matching surface 42, can make the second slider 3 slide more stably and reliably equivalent to the positioning block 4.

[0051] In addition, in this embodiment, as a preferred implementation form, refer again to Figure 1 As shown, the demoulding mechanism of the auxiliary instrument panel in this embodiment also includes a third slider 5 for abutting against the outer wall of the second side panel 12 in the auxiliary instrument panel 1. The third slider 5 slides along the first preset direction, and the third slider 5 and the first slider 2 are arranged correspondingly.

[0052] Furthermore, in this embodiment, as a preferred implementation form, the third slider 5 is provided with a second driving block 6, and the second driving block 6 has an abutting portion 61 abutting against the inner wall of the second side plate 12. When the third slider 5 slides away from the second side plate 12, the second driving block 6 can pull the second side plate 12 to flip back to the first side plate 11 and demold through the abutting portion 61, thereby reducing the demolding difficulty of the auxiliary instrument panel 1.

[0053] It is worth mentioning that the demoulding mechanism of the auxiliary instrument panel in this embodiment is a part of the auxiliary instrument panel forming mold and is combined with the auxiliary instrument panel. Figure 1 As shown, the auxiliary instrument panel forming mold of this embodiment also has a movable mold and a fixed mold (i.e., core) respectively arranged on the upper and lower sides of the auxiliary instrument panel 1. In the specific structure, the first slider 2 and the third slider 5 are respectively arranged on two opposite sides of the fixed mold along a first preset direction, and the cavity for molding the auxiliary instrument panel 1 is at least formed between the movable mold, the fixed mold, the first slider 2, the second slider 3, the third slider 5 and the second driving block 6.

[0054] The abutment portion 61 pulls the second side plate 12 to flip and demould away from the first side plate 11, which means that the second side plate 12 is demoulded relative to the fixed mold. When the demoulding operation is carried out, the sliding direction of the third slider 5 is opposite to that of the first slider 2.

[0055] At the same time, it should be noted that, in the present embodiment, each side panel of the auxiliary instrument panel 1 is respectively named as the first side panel 11 and the second side panel 12, which are mainly used to distinguish the first slider 2 from the third slider 5. During actual demolding, a plurality of first sliders 2 and a plurality of third sliders 5 are provided at each side panel of the auxiliary instrument panel 1, and each first slider 2 at one side panel is arranged one-to-one with each third slider 5 at the other side panel. This is because there is a requirement to set an undercut 10 on the inner side wall of each side panel, and after the undercut 10 is demolded, each side panel also has the requirement to be demolded relative to the fixed mold.

[0056] In addition, in this embodiment, as a preferred implementation form, a limiting mechanism is provided between the second driving block 6 and the third slider 5, and the limiting mechanism is used to limit the second driving block 6 from moving away from the second side plate 12 with the third slider 5 within a preset distance during the process of the second slider 3 being released from the undercut 10. The advantage of such a setting is that it can ensure that the flipping and demoulding action of the second side plate 12 does not interfere with the demoulding action of the undercut 10.

[0057] To elaborate, in the embodiment, as a preferred implementation form, the limiting mechanism includes a spring 7 disposed between the second driving block 6 and the third slider 5, and the third slider 5 abuts against the outer wall of the second side plate 12, and when the abutting portion 61 abuts against the inner wall of the second side plate 12, the spring 7 is in a compressed state. It can be understood that the provision of the spring 7 can ensure that before the second slider 3 is not disengaged from the undercut 10, the second driving block 6 will not move with the third slider 5, thereby ensuring that the demoulding operation of the undercut 10 proceeds smoothly.

[0058] Furthermore, in the specific implementation, continue to combine Figure 1 As shown, as a preferred embodiment, the second driving block 6 is slidably arranged on the third slider 5. At the same time, the limiting mechanism preferably includes a limiting portion 62 arranged at one end of the second driving block 6 away from the abutting portion 61, and a limiting groove 51 arranged along the first preset direction on the third slider 5. The limiting portion 62 slides in the limiting groove 51, and the length of the limiting groove 51 is equal to the preset distance, so that when the second slider 3 escapes from the undercut 10, the third slider 5 can drive the second driving block 6 to move, thereby performing a demolding operation relative to the fixed mold.

[0059] When the demoulding mechanism of the sub-instrument panel of this embodiment is implemented, the first slider 2 and the third slider 5 start to move along the first preset direction under the drive of the oil cylinder. Because the positioning block 4 is fixed on the first slider 2, the first driving block 41 on the positioning block 4 also drives the second slider 3 to move downward along the second preset direction, thereby disengaging from the undercuts 10 on the side panels of the sub-instrument panel 1. After the second slider 3 is completely disengaged from the undercuts 10, the third slider 5 drives the second driving block 6 to move together. At this time, under the action of the force of the second driving block 6, the side panels of the sub-instrument panel 1 will flip outward relative to the fixed mold until they are disengaged, thereby successfully completing the demoulding.

[0060] Of course, the auxiliary instrument panel 1, the auxiliary instrument panel demoulding mechanism and the related structural parts not mentioned in the auxiliary instrument panel forming mold in this embodiment can all refer to the structures of related products well known to those skilled in the art, such as Figure 2 As shown, the auxiliary instrument panel 1 includes, in addition to the first side panel 11 and the second side panel 12, a connecting plate 13 connected to the top of the first side panel 11 and the second side panel 12, and in actual applications, both the first side panel 11 and the second side panel 12 may be provided with undercuts 10, etc.

[0061] The demoulding mechanism of the auxiliary instrument panel in this embodiment can eliminate the design of the oil cylinder driving the second slider 3 to perform the demoulding action through the linkage setting of the first slider 2 and the second slider 3. This not only makes the structure simpler and helps to reduce the cost of mold design and development, but also saves usage space, shortens the molding cycle time of the product, improves the demoulding efficiency, and helps to ensure the demoulding quality of the undercut 10, thereby having a good demoulding effect.

[0062] Embodiment 2

[0063] The present embodiment relates to a subsidiary instrument panel forming mold, which is used to form a subsidiary instrument panel 1 having an undercut 10 on the inner wall, and the subsidiary instrument panel forming mold has the subsidiary instrument panel demoulding mechanism in the first embodiment.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
