[0002] The surface of the automobile interior trim panel is prepared by hot pressing. The hot pressing mold is divided into an upper and lower mold. The surface layer is attached between the molds. The mold heating and the adhesion effect of the cavity make the surface layer adhere to the surface of the interior trim panel.

[0003] During the hot pressing process of the surface layer, the surface layer is attached to the interior panel and highlights the shape of the interior panel. The surrounding material is the edge material, and the positioning holes opened on the edge material cooperate with the mold positioning pins to achieve fixation.

[0004] After processing is completed, demolding is required. The edge material is useless material, so there is no need to consider that the ejector will leave marks on the material during the ejection process. However, the edge material is easy to deform, so it cannot be used as an ejection point for ejection. The ejection structure is set in the mold forming area to eject the molded part, and the shape of the cavity and the punch is complex. There are many factors to consider when setting the ejection structure in the cavity and the punch, which increases the design difficulty and complicates the ejection structure. At the same time, it is also necessary to consider the impact of the ejection structure on the surface of the sheet. Summary of the invention

DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 9 Embodiment 1: In this embodiment: it includes an upper mold 1 and a lower mold 3, a fixed edge middle mold 2 which moves up and down is arranged between the upper mold 1 and the lower mold 3, and two rows of spring top cloth rods 32 are arranged in the non-forming area of ​​the lower mold 3, and the spring top cloth rods 32 and the fixed edge middle mold 2 clamp the edge material.

[0029] The improvement of this embodiment is that a fixed edge middle mold 2 is added between the upper mold 1 and the lower mold 3 , and the fixed edge middle mold 2 moves with the movement of the upper mold 1 .

[0030] The problem solved by the improvement of this embodiment is: using the edge material as a lifting point to solve the problem that the edge material is soft and cannot bear the load, and to reduce the mold complexity problem caused by the lifting of the material in the molding area.

[0031] Improved principle: The lower mold 3 is fixed at the bottom, and the fixed edge middle mold 2 moves with the movement of the upper mold 1. Figure 5, in the static state, the middle fixed-edge mold 2 does not contact the lower mold 3, and the surface layer is laid flat on the top of the lower mold 3. During the descending stage of the upper mold 1, the upper mold 1 contacts the middle fixed-edge mold 2, the middle fixed-edge mold 2 contacts the spring cloth pressing rod 32, and the edge material of the surface layer is clamped by the middle fixed-edge mold 2 and the spring cloth pressing rod 32. As the upper mold 1 continues to descend, the middle fixed-edge mold 2 continues to descend, and the spring cloth pressing rod 32 enters the interior of the lower mold 3 under the influence of the middle fixed-edge mold 2.

[0032] Please refer to Figure 6 , after the upper mold 1 is opened, the spring (not shown) below the spring cloth pressing rod 32 undergoes elastic deformation and resets, and the middle fixed-edge mold 2 rises with the upper mold 1. The spring cloth pressing rod 32 always contacts the middle fixed-edge mold 2, and the edge layer is always clamped by the spring cloth pressing rod 32 and the middle fixed-edge mold 2.

[0033] In summary, the problem of the edge material deformation and inability to eject is solved, and the technical effects brought are as follows: during the mold opening process, the edge clamping is realized, the mold structure is simplified, and the problem of damage to the material caused by the ejector is not required to be considered.

[0034] The further improvement point of this embodiment is that: a cloth inserting rod 321 is fixedly connected to the top of the spring cloth pressing rod 32, and a plugging hole 23 matching with the cloth inserting rod 321 is opened on the bottom surface of the middle fixed-edge mold 2.

[0035] The problem solved by the improvement point of this embodiment is that: the clamping between the middle fixed-edge mold 2 and the spring cloth pressing rod 32 depends on the frictional force, and it is difficult to clamp and eject due to the small frictional force on the surface of the fabric.

[0036] Improvement principle: Keep the existing surface layer positioning hole structure. A cloth inserting rod 321 is arranged at the top of the spring cloth pressing rod 32, and the cloth inserting rod 321 is positioned with the surface layer positioning hole. The diameter of the cloth inserting rod 321 is smaller than the diameter of the spring cloth pressing rod 32, and the stepped surface formed by the spring cloth pressing rod 32 and the cloth inserting rod 321 can lift the surface layer positioning hole. After the cloth inserting rod 321 is inserted and matched with the plugging hole 23, the edge material is ensured to be stable under the dual actions of hole limiting and clamping limiting.

[0037] In this embodiment, the shape of the middle fixed-edge mold 2 is a U-shaped, a groove body for fitting with the middle fixed-edge mold 2 is opened on the circumferential side of the bottom surface of the upper mold 1, the middle fixed-edge mold 2 and the lower mold 3 are elastically connected through an attaching spring 21, and an open end 22 is opened at one end of the middle fixed-edge mold 2.

[0038] In this embodiment, the formed workpiece will bulge upward. The advantage of the middle fixed-edge mold 2 having the open end 22 is that the clamping and conveying action of the deflector roller 42 on the edge material enables the workpiece to be removed through the open end 22. The attaching spring 21 can ensure that the middle fixed-edge mold 2 fits tightly when contacting the upper mold 1.

[0039] Embodiment 2: Based on Embodiment 1, the following improvements are made: In this embodiment: the bottom of the fixed edge middle mold 2 is slidably connected with a top cloth clamping mechanism 4, and the top cloth clamping mechanism 4 performs edge clamping and edge feeding actions according to the movement position of the fixed edge middle mold 2.

[0040] Problem to be solved: After the edge material is clamped, the material needs to be sent out from the mold. The clamping structure is not conducive to the material being sent out, and the applicability for continuous production and processing is poor.

[0041] Improvement principle: Please refer to Figure 5 After the upper mold 1 continues to rise, the fixed edge middle mold 2 will separate from the spring top cloth rod 32. If the fixed edge middle mold 2 and the spring top cloth rod 32 are not separated, the edge material will always be in the clamping state of the spring top cloth rod 32 and the fixed edge middle mold 2, which is not conducive to separation from the workpiece.

[0042] See also Figure 6 After the fixed edge middle mold 2 and the spring cloth push rod 32 are lifted to the critical state of separation, the cloth push clamping mechanism 4 moves inward to clamp the plate. Figure 7 , the fixed edge middle mold 2 continues to lift up, the fixed edge middle mold 2 is separated from the spring cloth-lifting rod 32, and the cloth-lifting and clamping mechanism 4 clamps the edge material at the fixed edge middle mold 2. The clamping mode of the edge material by the spring cloth-lifting rod 32 and the fixed edge middle mold 2 is converted into the clamping mode of the cloth-lifting and clamping mechanism 4 and the fixed edge middle mold 2. The cloth-lifting and clamping mechanism 4 can use the clamping effect of the edge material to drive the material to be sent out.

[0043] Technical effect: the problem of obstruction of material delivery caused by the edge material clamping structure during continuous production and processing after the cloth insertion rod 321 is set is solved.

[0044] The implementation method of the top feeding and cloth clamping mechanism 4 in this embodiment is as follows: the top feeding and cloth clamping mechanism 4 includes a horizontal slide plate 41 and a direction-changing roller 42. The horizontal slide plate 41 is slidably connected to the fixed edge middle mold 2. The direction-changing roller 42 is driven to rotate by a direction-changing driver 43. The horizontal slide plate 41 is rotatably connected with the direction-changing roller 42. The rotation angle of the direction-changing roller 42 is 90 degrees. There are multiple direction-changing rollers 42, and the multiple direction-changing rollers 42 are linearly distributed on the top of the horizontal slide plate 41. An adjustable groove body 31 is provided on the side of the lower mold 3. The adjustable groove body 31 consists of a groove body and a slider. The slider slides in the groove body. The slider is driven and controlled by any method of a cylinder, an oil cylinder, or an electric push rod. A concave groove body is formed when the slider is in a retracted state. When the slider is in an ejected state, the concave surface of the groove body is filled. The bottom surface of the horizontal slide 41 is fixedly connected with a contact rod wheel 44, which slides on the side wall of the lower mold 3 and the inner wall of the adjustable groove body 31. The horizontal slide 41 is slidably connected to the fixed edge middle mold 2 through a sliding mechanism 24, and a return spring is arranged in the sliding mechanism 24.

[0045] The principle of the above implementation is as follows: Fig. 9, the upper mold 1 is at the original starting point, the fixed edge middle mold 2 is lifted to the highest point, the fixed edge middle mold 2 is separated from the spring top cloth rod 32, and the slider of the adjustable trough 31 is in the ejected state, the concave surface of the trough is filled, the horizontal slide 41 is located away from the spring top cloth rod 32, and the spring in the sliding mechanism 24 is in an elastic deformation state. When installing the fabric, the fabric is positioned by the cloth insertion rod 321, and the top feeding and clamping mechanism 4 will not interfere with the installation of the fabric. In the pressed state, the fixed edge middle mold 2 descends, and the fabric is clamped by the fixed edge middle mold 2 and the spring top cloth rod 32; the reversing roller 42 moves to the side of the lower mold 3, and the fixed edge middle mold 2 continues to descend; in the closed mold state, the fixed edge middle mold 2, the spring top cloth rod 32, and the lower mold 3 clamp the edge material of the facing layer.

[0046] In the mold open state, please refer to Figure 6 , the slider of the adjustable trough body 31 is retracted to form a concave trough body. After the fixed edge middle mold 2 is lifted, during the period of the spring top cloth rod 32 and the fixed edge middle mold 2 clamping the edge material, the contact rod wheel 44 moves to the concave part of the adjustable trough body 31, and the contact rod wheel 44 carries the horizontal slide plate 41 to move toward the forming area. When the change-direction roller 42 moves toward the forming area, it rolls the edge material and provides vertical support force for the edge material. After the change-direction roller 42 clamps the edge material, when the fixed edge middle mold 2 and the spring top cloth rod 32 are not separated, the change-direction driver 43 drives the change-direction roller 42 to rotate 90 degrees, and the rotation axis of the change-direction roller 42 changes 90 degrees. The fixed edge middle mold 2 continues to rise, the fixed edge middle mold 2 is separated from the spring top cloth rod 32, the top feeding and clamping mechanism 4 and the fixed edge middle mold 2 continue to rise with the edge material, the cloth insertion rod 321 is separated from the edge material hole and the plug hole 23, and the change-direction roller 42 drives the edge material and the workpiece to move toward the open end 22.

[0047] Design advantages: Combined with the existing movement direction of the upper mold 1, the top feeding and clamping mechanism 4 is added to solve the separation problem of the edge material and the spring top cloth rod 32. After solving this problem, the processing and discharging action of the device is smooth, meeting the continuous processing requirements.

[0048] Further improvement of this embodiment: a cloth pressing rod 322 is fixedly connected to the top surface of the spring cloth pushing rod 32 near the cloth pushing clamping mechanism 4, and the cloth pressing rod 322 is flush with the top surface of the spring cloth pushing rod 32. The spring cloth pushing rod 32 is flush with the top surface of the lower mold 3 in the stored state.

[0049] Problem to be solved: The edge of the edge material away from the spring top cloth rod 32 is a soft edge. After the spring top cloth rod 32 lifts the edge material of the fabric, the edge material will bend downward due to the influence of gravity, and the changing roller 42 cannot press the edge material.

[0050] Solution: A cloth pressing rod 322 is fixed on the side of the top of the spring top cloth rod 32 away from the cavity. The cloth pressing rod 322 supports the edge of the fabric, and the edge of the fabric cannot bend downward. The contact rod wheel 44 moves toward the cavity to press the edge of the fabric.

[0051] Supplementary explanation of this embodiment: the contact rod wheel 44 is located between two adjacent cloth pressing rods 322. This distribution mode enables the contact rod wheel 44 to press the edge of a larger area of ​​fabric. The direction-changing roller 42 located at the end is a power wheel, and the power wheel can be controlled to rotate by external power supply and motor.

[0052] Instructions: Step 1, please refer to Figure 5 a in: Figure 5 a in the figure is the starting stage, the slider of the adjustable trough 31 is in the ejection state, and the concave surface of the adjustable trough 31 is closed. The contact rod wheel 44 is affected by the ejection of the slider of the adjustable trough 31 to drive the horizontal slide 41 to move to the side away from the cavity, and the sliding mechanism 24 undergoes elastic deformation and shrinks to store energy. There is a gap between the fixed edge mold 2 and the spring top cloth rod 32, and the gap is used to install the surface layer. The hole body of the surface layer is inserted into the cloth insertion rod 321 to complete the surface installation step.

[0053] Step 2, see Figure 5 b: The upper mold 1 descends, and contacts the fixed edge middle mold 2. The upper mold 1 drives the fixed edge middle mold 2 to descend, and the attached spring 21 undergoes elastic deformation. The fixed edge middle mold 2 descends until it contacts the spring top cloth rod 32, and the cloth insertion rod 321 is inserted into the plug hole 23. The surface layer hole body is cooperated by the cloth insertion rod 321 and the plug hole 23 to achieve the two functions of perforation positioning and clamping and fixing.

[0054] Step 3, see Figure 5 c in the figure: the upper mold 1 continues to descend, the upper mold 1 and the lower mold 3 are closed, the fixed edge middle mold 2 descends and synchronously drives the spring top cloth rod 32 to descend, the spring at the bottom of the spring top cloth rod 32 undergoes elastic deformation and compression to store energy, the fixed edge middle mold 2 is stored in the edge groove body of the upper mold 1, and the change-of-direction roller 42 and the contact rod wheel 44 slide on the side of the lower mold 3.

[0055] Step 4, see Figure 6 a- Figure 6c in the figure: in the mold opening stage, the slider of the adjustable trough body 31 is in a contracted state, the concave surface of the adjustable trough body 31 is formed, the upper mold 1 rises, the attached spring 21 is elastically reset and pushes the fixed edge middle mold 2 to contact the upper mold 1. The spring inside the spring top cloth rod 32 is elastically reset, the spring top cloth rod 32 rises, the spring top cloth rod 32 and the fixed edge middle mold 2 are relatively static, the spring top cloth rod 32 and the attached spring 21 keep in contact with each other and clamp and lift the edge material. The edge material is lifted and exerts a force on the molded part, and the molded part is separated from the cavity or the punch. The contact rod wheel 44 enters the trough body of the adjustable trough body 31, the spring inside the sliding mechanism 24 is elastically deformed, the contact rod wheel 44 carries the horizontal slide plate 41 to move toward the cavity area, the direction-changing roller 42 rolls the edge material below the fixed edge middle mold 2, and the direction-changing roller 42 and the fixed edge middle mold 2 form a clamping force on the edge material.

[0056] Step 5, see Figure 7 a- Figure 7 c: The upper mold 1 continues to rise, and before the spring top cloth rod 32 reaches its limit, the direction-changing driver 43 drives the direction-changing roller 42 to rotate 90 degrees, and the direction of rotation of the direction-changing roller 42 is changed from the direction toward the cavity to the direction toward the open end 22, and the fixed edge middle mold 2 continues to rise, and the cloth insertion rod 321 is separated from the insertion hole 23. The supporting force exerted by the direction-changing roller 42 on the edge material causes the edge material to rise, and the hole of the edge material is separated from the cloth insertion rod 321, and the direction-changing roller 42 rotates toward the open end 22, and the direction-changing roller 42 drives the edge material to move from the open end 22, and the molded part carrying the edge material is discharged through the open end 22.

[0057] Step 6: After discharge, the direction of rotation of the direction-changing roller 42 is reset, the slider of the adjustable trough body 31 is in the ejection state, and step 1 is repeated.

[0058] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
