Abstract
Description
Technical Field
[0001] This utility model applies to the field of automotive decorative panel production technology, and in particular relates to an automotive decorative panel hole cutting mold. Background Technology
[0002] Currently, automotive trim panels are components installed inside and outside automobiles for decoration, protection, and to achieve certain functions. They not only enhance the aesthetics of automobiles but also improve driving comfort and safety, making them an important part of automotive interior and exterior trim. To facilitate the installation and fixing of automotive trim panels, corresponding cutting molds are used to create openings in the appropriate functional positions on the surface of the trim panels.
[0003] However, current cutting molds used for drilling holes in automotive trim panels often have internal positioning slots to fix the cutting position of the cutting blade. However, the diameter of these positioning slots cannot be adjusted for different hole diameters. This leads to the cutting blade easily wobbling during movement, affecting the quality of the hole drilling and grooving on the automotive trim panel surface. Therefore, we propose a new cutting mold for automotive trim panel holes. Utility Model Content
[0004] The main purpose of this utility model is to provide a cutting mold for holes in automotive decorative panels, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A cutting mold for holes in automotive decorative panels includes a fixed frame, a handrail fixedly installed at the middle of the side of the fixed frame, abutting frames slidably installed on both sides inside the fixed frame, an abutting plate slidably installed between the inner sides of the two sets of abutting frames, and a movable groove opened inside the middle of each abutting frame, with the outer side of the abutting plate slidably attached to the inner wall of the movable groove.
[0007] A limiting mechanism is provided on the outside of the fixed frame, and the limiting mechanism is connected to the abutting frame and the abutting plate in a transmission manner.
[0008] As an optional solution to the technical solution of this application, a first connecting rod is fixedly installed at the middle of the side of each abutting frame, and a second connecting rod is fixedly installed at both ends of the side of each abutting plate. A guide groove is provided on the side of the fixed frame, and the first connecting rod and the second connecting rod are both slidably installed inside the guide groove.
[0009] As an optional solution to the technical solution of this application, the limiting mechanism includes a clamping bolt, a first sliding frame is fixedly installed on the top side of each first connecting rod, a second sliding frame is fixedly installed on the side of each second connecting rod, and the first and second sliding frames are slidably attached to the outside of the fixed frame. The top middle of each first and second sliding frame is threadedly screwed with a clamping bolt. A limiting slot is opened on the outer side of the top of the fixed frame, and the number of limiting slots is four. The bottom of the clamping bolt is movably inserted into the limiting slot.
[0010] By adopting the above technical solution, the distance between the abutting frame and the abutting plate can be adjusted by the tightening action of the abutting bolt and the connecting transmission action of the first connecting rod and the second connecting rod. This allows for the applicability adjustment of the inner diameter of the positioning structure composed of the abutting frame and the abutting plate, so that the hole cutter can perform hole cutting processing on the surface of the automotive decorative panel under the limiting action of the abutting frame and the abutting plate.
[0011] As an optional solution to the technical solution of this application, connecting columns are vertically fixedly installed on both sides of the bottom of the fixed frame, and a fixed suction cup is fixedly installed at the bottom of each connecting column.
[0012] By adopting the above technical solution, the fixed frame and its internal abutment frame and abutment plate can be adsorbed and fixed to the surface of the car trim panel through the structure of the fixed suction cup, which facilitates the use of the abutment frame and abutment plate to position the hole cut.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. A cutting mold for holes in automotive decorative panels according to the present application comprises a first sliding frame and a second sliding frame slidably mounted on the outside of a fixed frame, and the first and second sliding frames are connected to a stop frame and a stop plate respectively by means of a first connecting rod and a second connecting rod. When the operator pushes the first and second sliding frames, the stop frame and the stop plate can move synchronously inside the fixed frame under the transmission action of the first and second connecting rods. This allows the stop plate to move inside the stop frame, thereby adjusting the distance between the stop frame and the stop plate. This allows for the applicability adjustment of the inner diameter of the positioning structure composed of the stop frame and the stop plate, so that the hole cutter can perform hole cutting processing on the surface of the automotive decorative panel under the limiting action of the stop frame and the stop plate.
[0015] 2. The automotive trim panel hole cutting mold of this application provides a fixed suction cup at the bottom of the fixed frame. When the fixed frame needs to be positioned for hole cutting, the fixed frame and its internal abutment frame and abutment plate can be adsorbed and fixed to the surface of the automotive trim panel by the adsorption force of the fixed suction cup itself, which facilitates the use of the abutment frame and abutment plate for hole cutting.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a cutting mold for holes in automotive decorative panels, wherein connecting columns are vertically fixedly installed on both sides of the bottom of the fixed frame, and a fixed suction cup is fixedly installed at the bottom of each connecting column.
[0021] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a first sliding frame is fixedly installed on the top side of each of the first connecting rods, and a second sliding frame is fixedly installed on the side of each of the second connecting rods. The first and second sliding frames are slidably attached to the outside of the fixed frame. A tightening bolt is screwed through the top middle of each of the first and second sliding frames by a thread. A limit slot is opened on the outer side of the top of the fixed frame, and there are four sets of limit slots. The bottom of the tightening bolt is movably inserted into the limit slot.
[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown, a first connecting rod is fixedly installed at the middle of the side of each abutment frame, and a second connecting rod is fixedly installed at both ends of the side of each abutment plate. A guide groove is provided on the side of the fixed frame, and the first and second connecting rods are slidably installed inside the guide groove.
[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a handrail is fixedly installed at the middle of the side of the fixed frame, and abutment frames are slidably installed on both sides inside the fixed frame. An abutment plate is slidably installed between the inner sides of the two sets of abutment frames. A movable groove is opened inside the middle of each abutment frame, and the outer side of the abutment plate slides against the inner wall of the movable groove.
[0024] During operation, when hole cutting is required on the surface of the automotive trim panel, the fixing frame is continuously pressed down, causing its bottom suction cup to adhere to the surface of the trim panel to be processed. Then, the clamping bolt is tightened, causing its bottom to move out of the inner wall of the limiting slot. This releases the clamping bolt's resistance to the first and second sliding frames, pushing the opposing first sliding frame horizontally. Under the connecting transmission of the first connecting rod, the abutment frame moves synchronously in the same direction. The outer sides of the abutting plates move horizontally towards each other until the two sets of abutting frames can move to the corresponding distance so that their sides can be adapted to the diameter of the hole cut. Then, the tightening bolts on the top of the first sliding frame are tightened so that its bottom fits into the inner wall of the limiting slot, and the first sliding frame is abutted and limited. Then, the distance between the second sliding frame and the abutting plates is adjusted repeatedly so that the two sets of abutting plates can also be adapted to the diameter of the hole cut. The position adjustment of the abutting frames and abutting plates is completed, ensuring that the abutting frames and abutting plates can provide positioning assistance for the hole cutting tool.
