Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, and more specifically to a mold structure for molding large automobile interior decoration parts. Background Art

[0002] With the continuous improvement of material living standards, the automobile industry is becoming an indispensable item in people's daily life and is developing rapidly. The quality requirements of automobile interior and exterior trims are also increasing.

[0003] The dashboard is a crucial interior component in automobile manufacturing and assembly. Its cross-section is typically V-shaped, and it directly faces the driver and passengers. Its aesthetics directly reflect the overall quality of the car, making its importance self-evident. The dashboard has a complex structure, numerous assembly dimensions, and high precision requirements, along with a large visible surface area. Therefore, high precision and high quality are essential when manufacturing the mold.

[0004] Some existing car dashboards are integrated with airbag assemblies. The airbag assemblies are generally arranged in an airbag assembly space inside the car dashboard. When the car dashboard is formed, a mold is used to simultaneously form the airbag assembly space inside the car dashboard.

[0005] The structure of the car dashboard changes more complexly after the airbag assembly space is increased, and a large downward slope angle will be generated on the inside of the dashboard. If the demoulding structure of the car dashboard on the molding mold is unreliable, it is very easy to cause jamming and damage during production, resulting in low yield rate and mold scrapping, affecting the entire car production line. A reliable and safe demoulding structure is needed to ensure safe and efficient production and meet the requirements of automatic production by robots.

[0006] In addition, during the molding process of the automobile dashboard, an insert nut needs to be set on the punch to form a connecting hole on the automobile dashboard. The existing insert nut is generally set at the front end of the punch, and a threaded connector is inserted into the rear end of the punch to connect with the insert nut, which brings great difficulties to the replacement operation. Too many parts need to be disassembled and cannot meet the usage requirements. Utility Model Content

[0007] In view of the shortcomings and defects of the existing technology, a mold structure for molding large automotive interior parts is provided to improve the yield rate.

[0008] A mold structure for molding large automotive interior parts, comprising:

[0009] A punch and an airbag inclined top movably arranged on the punch, wherein the airbag inclined top is used for forming the airbag assembly space inside the automobile instrument panel;

[0010] The ejection mechanism is arranged below the punch and includes a push plate, a slide seat, and an inclined ejector rod;

[0011] The push plate moves up and down along axis A, and the slide is arranged on the push plate and moves left and right along axis B;

[0012] The sliding seat is provided with a universal slider that can move along the axis C, and the axis C is consistent with the moving direction of the airbag inclined top;

[0013] The universal slider is provided with a guide rod, which is connected to the airbag inclined top. After the automobile dashboard is formed, the push plate moves upward along the axis A, the slide moves left along the axis B, and the universal slider moves right along the axis C. The inclined top of the airbag is driven to move parallel to the axis C through the inclined top rod, thereby playing the role of lifting the material in the area of ​​​​the assembly space.

[0014] After adopting the above structure, the mold structure for molding large automobile interior parts of the utility model has the following advantages compared with the prior art:

[0015] The push plate is provided with an ejector pin which penetrates into the punch.

[0016] When the car dashboard is demoulded, the push plate moves upward, and the car dashboard body moves upward (along axis A) under the action of the ejector pin.

[0017] At the same time, the slide moves to the left along axis B, and the universal slider moves to the right along axis C. During the movement, the airbag lifter is driven to move parallel to axis C by the lift rod, and the position of the airbag assembly space of the car dashboard is ejected, so that the more inclined area of ​​the car dashboard can gradually move away from the punch during the demoulding process, avoiding the more inclined area of ​​the car dashboard being directly demoulded upward and getting stuck between the punch, thereby improving the product yield.

[0018] As an improvement of the present invention, there are two lifting mechanisms, one of which is arranged corresponding to the front end of the airbag inclined top, and the inclined lifting rod of the lifting mechanism is connected to the front end of the airbag inclined top, and the other lifting mechanism is arranged corresponding to the tail end of the airbag inclined top, and the inclined lifting rod of the lifting mechanism is connected to the tail end of the airbag inclined top.

[0019] As an improvement of the present invention, a bottom plate is provided below the push plate, a guide rod is provided on the bottom plate along the axis D, and the slide seat is provided with a bearing for the guide rod to penetrate.

[0020] As an improvement of the present invention, the base plate is provided with a guide rod parallel to the axis A;

[0021] There are multiple guide rods, and the push plate is provided with a guide sleeve for the guide rod to penetrate.

[0022] As an improvement of the present invention, the ejecting mechanism further includes a plurality of push rods, which are arranged around the push plate, and the main bodies of the push rods are fixed, and the telescopic ends are connected to the push plate.

[0023] As an improvement of the present invention, the punch is provided with inserts at the left and right ends corresponding to the inclined top of the airbag, and the inserts are provided with insert nuts for forming connecting holes at both ends of the airbag assembly space;

[0024] The insert is provided with front and rear through-holes, the tail end of the assembly hole is penetrated by an insert pin fixing seat, and the front end of the assembly hole is provided with a magnet.

[0025] The insert nut is arranged at the front end of an inlay pin, and the tail end of the inlay pin is inserted from the front end of the assembly hole and passes through the magnet to be threadedly connected with the inner hole of the inlay pin fixing seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] See also Figure 1-10 As shown, a mold structure for molding large automotive interior parts includes:

[0039] A punch 1 and an airbag inclined top 2 movably arranged on the punch 1, wherein the airbag inclined top 2 is used to form an airbag assembly space 8.1 inside the vehicle instrument panel 8;

[0040] The ejection mechanism is arranged below the punch 1 and includes a push plate 3, a slide 4, and an inclined ejector rod 5;

[0041] The push plate 3 moves up and down along the axis A, and the slide 4 is arranged on the push plate 3 and moves left and right along the axis B;

[0042] The slide 4 is provided with a universal slider 4.1 that can move along the axis C, and the axis C is consistent with the movement direction of the airbag inclined top 2;

[0043] The universal slider 4.1 is provided with a guide rod 6.2, which is connected to the airbag lift 2. After the automobile dashboard 8 is formed, the push plate 3 moves upward along the axis A, the slide 4 moves left along the axis B, and the universal slider 4.1 moves right along the axis C. The lift rod 5 drives the airbag lift 2 to move parallel to the axis C, thereby playing a role in lifting the material in the area of ​​​​the assembly space.

[0044] The device also has a concave mold for forming the outer area of ​​the car instrument panel 8 (not shown in the figure);

[0045] The punch 1 is used to form the inner area of ​​the vehicle instrument panel 8. As can be seen from the accompanying drawings, one side wall of the vehicle instrument panel 8 is inclined at a large angle. The airbag assembly space 8.1 is located within this inclined side wall, so the cavity surface of the airbag inclined top 2 is also inclined.

[0046] The push plate 3 is provided with an ejector pin which penetrates the punch 1.

[0047] When the car instrument panel 8 is demoulded, the push plate 3 moves upward to drive the ejector pin to be ejected upward, and the main body of the car instrument panel 8 moves upward (along the axis A) under the action of the ejector pin.

[0048] At the same time, the slide 4 moves to the left along the axis B, and the universal slider 4.1 moves to the right along the axis C. During the movement, the airbag lift 2 is driven to move parallel to the axis C by the lift rod 5. From the attached figure, the airbag lift 2 can be used to tilt the area of ​​the car dashboard 8 upward, so that the more inclined area of ​​the car dashboard 8 can be away from the punch 1 during the demolding process, avoiding the more inclined area of ​​the car dashboard 8 being directly demolded upward and getting stuck between the punch 1, thereby improving the product yield.

[0049] As an improvement of the present invention, there are two lifting mechanisms, one of which is arranged corresponding to the front end of the airbag inclined ejector 2, and the inclined ejector rod 5 of the lifting mechanism is connected to the front end of the airbag inclined ejector 2, and the other lifting mechanism is arranged corresponding to the tail end of the airbag inclined ejector 2, and the inclined ejector rod 5 of the lifting mechanism is connected to the tail end of the airbag inclined ejector 2.

[0050] After the above improvements, multiple ejection mechanisms are provided to jointly transmit the airbag inclined ejector 2 during the demoulding process, so that the airbag inclined ejector 2 can move smoothly and reliably.

[0051] As an improvement of the present invention, a base plate 6 is provided under the push plate 3, a guide rod 6.1 is provided on the base plate 6 along the axis D, and the slide seat 4 is provided with a bearing for the guide rod 6.1 to penetrate and slide into, wherein the axis D and the axis of the inclined push rod 5 are arranged in a cross structure.

[0052] After the above improvements, when the push plate 3 moves upward, under the action of the guide rod 6.1, the slide 4 moves to the left along the axis B. When the push plate 3 moves downward, the guide rod 6.1 drives the slide 4 to move right along the axis B and reset. The cooperation between the bearing and the guide rod 6.1 can ensure reliable operation and long service life.

[0053] As an improvement of the present invention, the base plate 6 is provided with a guide rod 6.2 parallel to the axis A;

[0054] There are multiple guide rods 6.2, and the push plate 3 is provided with a guide sleeve for the guide rod 6.2 to penetrate and slide into.

[0055] The number of guide rods 6.2 is preferably 6, two of which are arranged on a row of base plates 6 at intervals along the length of the push plate 3, and a guide sleeve is provided on the push plate 3 to match each guide rod 6.2. After the above structure is improved, the up and down movement process of the push plate 3 is stable and reliable, thereby achieving a better demoulding effect. The cooperation between the guide sleeve and the guide rod 6.2 can ensure reliable operation and a long service life.

[0056] As an improvement of the present invention, the ejecting mechanism further includes a plurality of push rods 7 , which are arranged around the push plate 3 , and the main bodies of the push rods 7 are fixed, and the telescopic ends are connected to the push plate 3 .

[0057] After the above improvements, the push rod 7 is used to drive the push plate 3 to move up and down, which has the characteristics of stable and reliable operation.

[0058] As an improvement of the present invention, the punch 1 is provided with inserts 9 at the left and right ends corresponding to the airbag inclined top 2, and the inserts 9 are provided with insert nuts 10 for forming connecting holes 8.2 at both ends of the airbag assembly space 8.1;

[0059] The insert 9 is provided with front and rear through-holes 9.1;

[0060] Among them, the pin fixing seat 11 is fixed at the tail end of the assembly hole 9.1, and the pin fixing seat 11 is a cylindrical structure;

[0061] The magnet 12 is fixed to the front end of the assembly hole 9.1, and the inner hole of the magnet 12 is coaxial with the inner hole of the pin fixing seat 11;

[0062] The tail end of the inlay pin 13 passes through the magnet 12 and is fixed to the inner hole of the inlay pin fixing seat 11 by thread. A tightening portion 13.1 is provided in the middle of the inlay pin 13 for tightening the magnet 12. The front end of the inlay pin 13 is used to sleeve the insert nut 10, and the tail end of the insert nut 10 is magnetically connected to the magnet 12.

[0063] After the above improvements, the insert pin 13 and the insert nut 10 are fixed from the front of the punch 1, and can be replaced more conveniently. If they are damaged during the production process, they can be operated on the injection molding machine, which greatly saves time. In addition, the magnetic attraction of the magnet 12 is used to fix the insert nut 10 to prevent the insert nut 10 from falling during the movement of the mold, thereby improving the stability and making the device run reliably.
