[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: a tooling for forming a notched molded part, including an upper module 1, a lower module 2 disposed on the lower surface of the upper module 1, the two cooperating to form the forming space of the molded part, an upper protrusion 3 fixedly installed on the top inner wall of the upper module 1, and a lower protrusion 4 fixedly installed on the bottom inner wall of the lower module 2, the upper protrusion 3 and the lower protrusion 4 are used to shape specific parts of the molded part during the molding process to ensure the shape accuracy of the molded part, notched cavities 5 are provided on the inner surfaces of the upper module 1 and the lower module 2, the notched cavities 5 are adapted to the notch shape required for the molded part, providing space for the forming of the notch of the molded part, and elastic extrusion devices 6 are provided on the outer surfaces of the upper module 1 and the lower module 2, the elastic extrusion devices 6 playing a key role in the molding and demolding process.

[0021] The elastic compression device 6 includes a fixed horizontal plate 601 fixedly installed on the upper surface of the upper module 1 and the lower surface of the lower module 2. The fixed horizontal plate 601 serves to support and fix subsequent components. A compression spring 602 is fixedly installed on the outer side of the fixed horizontal plate 601. The compression spring 602 is the core component for realizing the elastic function of the elastic compression device 6. It can provide adjustable compression force. A movable horizontal frame 603 is fixedly installed on the outer end of the compression spring 602. The movable horizontal frame 603 can move horizontally under the action of the compression spring 602. The top of the movable horizontal frame 603 is provided with a rotatable linkage rod 604. There are two sets of linkage rods 604, and the length of the two sets of linkage rods 604 is... All lengths are 450 mm. This length design ensures both sufficient transmission stroke and structural stability. The top of the linkage rod 604 is equipped with a rotatable linkage bracket 605, which can convert the horizontal movement of the linkage rod 604 into vertical movement. A fixed column 606 is fixedly installed on the lower surface of the linkage bracket 605, and a pressing protrusion 607 is fixedly installed on the lower surface of the fixed column 606. The pressing protrusion 607 is used to press the molded part. A blocking cross block 608 is fixedly installed on the upper surface of the pressing protrusion 607. The blocking cross block 608 can prevent the pressing protrusion 607 from moving excessively, ensuring the safety and stability of the pressing operation.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, both the upper module 1 and the lower module 2 have arc-shaped grooves on their outer surfaces. The depth of the arc-shaped grooves is eighty millimeters. The design of the arc-shaped grooves can reduce the overall weight of the tooling on the one hand, and provide a certain space for the installation and operation of the elastic extrusion device 6 on the other hand, while optimizing the structure of the tooling in terms of appearance.

[0023] Specifically, such as Figure 3As shown, a movable slider is fixedly installed on the lower surface of the movable crossbar 603. Movable grooves are provided on the upper surface of the upper module 1 and the lower surface of the lower module 2. The movable slider is slidably connected to the movable groove. This structural design makes the movable crossbar 603 more stable during movement and ensures the normal operation of the elastic extrusion device 6. Rectangular through holes are provided inside the upper module 1 and the lower module 2. The size of the rectangular through holes is adapted to the size of the extrusion protrusion 607. The extrusion protrusion 607 can accurately extrude the molded part through the rectangular through holes.

[0024] The working principle of this utility model is as follows:

[0025] S1. First, according to the size and shape requirements of the molded part to be processed, adjust the elastic extrusion device 6, and compress the extrusion spring 602 by manual or mechanical means to move the moving crossbar 603 inward, thereby driving the linkage rod 604, linkage bracket 605, fixed column 606 and extrusion protrusion 607 to move. Adjust the position of the extrusion protrusion 607 in the rectangular through hole to ensure that it matches the position and size of the notch of the molded part. At the same time, check the fit between the moving slider and the moving slide to ensure that the moving crossbar 603 can slide smoothly.

[0026] S2. Place the raw material to be processed in the forming space between the upper module 1 and the lower module 2, start the molding equipment, and the upper module 1 and the lower module 2 gradually approach each other under the action of the molding equipment. The upper protrusion 3 and the lower protrusion 4 perform preliminary shaping on the raw material. At the same time, under the action of the compression spring 602, the elastic extrusion device 6 and the extrusion protrusion 607 simultaneously extrude the notch of the molded part, so that the raw material gradually fills the notch cavity 5 under the action of pressure, and completes the molding process of the molded part.

[0027] S3. After molding is completed, the upper module 1 of the molding equipment is driven to move upward. At this time, the elastic extrusion device 6 plays a role, and the extrusion spring 602 gradually returns to its original state, pushing the moving crossbar 603 to move outward. Through the linkage rod 604 and the linkage bracket 605, the extrusion protrusion 607 is driven to move upward, so that the molded part is gradually separated from the notch cavity 5. Due to the buffering effect of the extrusion spring 602, the external force at the notch of the molded part is relatively uniform, effectively avoiding the generation of cracks and deformation. After the molded part is completely separated from the tooling, the molded part can be taken out, completing one molding process.

[0028] In summary, the tooling for forming notched molded parts, by incorporating the elastic extrusion device 6, allows the extrusion spring 602 to provide buffering force during demolding, gradually separating the molded part from the notch in the tooling. This avoids cracking and deformation at the notch caused by excessive instantaneous external force, significantly improving the yield rate of molded parts. The adjustability of the elastic extrusion device 6 enables the tooling to adapt to the production of notched molded parts with different sizes and shapes. By adjusting the compression degree of the extrusion spring 602, the magnitude of the extrusion force can be changed to meet the processing requirements of molded parts with different materials and processes.
