All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0021] Example

[0022] This utility model provides a mold installation and positioning fixture, such as Figures 1-3 As shown, the device includes a first positioning seat 1 and a second positioning seat 2. A first mounting groove is formed on the sidewalls of the first positioning seat 1 and the second positioning seat 2 opposite to the first positioning seat 1. A second mounting groove 5 is formed on the sidewall of the second positioning seat 2 opposite to the first positioning seat 1. A positioning pin 3 is installed in the first mounting groove, and a movable mold 9 is installed on the free end of the positioning pin 3. A fixed mold 6 is installed in the second mounting groove 5. The movable mold 9 extends outward after passing through the fixed mold 6, and an annular channel exists between the movable mold 9 and the fixed mold 6. The axial positioning of the movable mold 9 and the fixed mold 6 is achieved through the rigid connection between the positioning pin 3 and the mounting groove. The fixed mold 6 is fixed to the second positioning seat 2 to provide a forming reference surface. The annular channel formed between the movable mold 9 and the fixed mold 6 is used to control the material forming direction and forming size. In use, the first positioning seat 1 and the second positioning seat 2 are fixed relative to each other. The moving mold 9 is installed in the first mounting groove through the positioning pin 3, and the fixed mold 6 is fixed in the second mounting groove 5. The moving mold 9 extends through the fixed mold 6 and forms an annular channel between the two. It is used for extrusion or filling during material forming or drawing. The coaxiality of the moving mold 9 and the fixed mold 6 is ensured by the mounting grooves respectively set on the first positioning seat 1 and the second positioning seat 2, which improves the forming accuracy. The annular channel can accurately control the cross-sectional shape of the product and is suitable for continuous forming processes such as pipes and wires.

[0023] In some technical solutions of this utility model, a limiting ring is provided on the outer wall of the positioning post 3, and a first screw structure is provided on the limiting ring that is detachably connected to the first positioning seat 1. The limiting ring and the screw form an axial constraint to prevent the positioning post 3 from displacing due to force during material extrusion or drawing. The limiting ring and the outer side of the positioning post 3 are integrally formed and are machined by turning process to improve the overall strength of the two. The first screw structure (such as a bolt) is locked to the first positioning seat 1 to restrict the axial movement of the positioning post 3, enhance the stability of the moving mold 9, and avoid product defects caused by displacement during the molding process. The detachable screw facilitates quick replacement or adjustment of the positioning post 3 and improves adjustment efficiency.

[0024] In some technical solutions of this utility model, an assembly port is provided on the side wall of the moving mold 9 along its axial direction, and a groove is provided on the free end of the positioning pin 3. The moving mold 9 is partially embedded in the groove, and a second screw structure 8 connected to the groove is installed in the assembly port. The engagement of the groove and the assembly port provides radial support, and the second screw further strengthens the connection. The assembly port of the moving mold 9 is embedded in the groove at the end of the positioning pin 3 and locked by the second screw structure 8 (such as a threaded pin), thereby achieving radial fixation between the moving mold 9 and the positioning pin 3 and preventing the moving mold 9 from loosening due to torque or lateral force. The modular design facilitates the individual replacement of the moving mold 9 and reduces maintenance costs.

[0025] In some technical solutions of this utility model, a plurality of positioning holes are provided on the side wall of the fixed mold 6, and positioning pins 3 connected to the second mounting groove 5 are provided in the positioning holes. The cooperation between the positioning pins 3 and the positioning holes restricts the rotation of the fixed mold 6, ensuring the circumferential uniformity of the annular channel. The positioning pins 3 (or positioning pins) are inserted into the positioning holes on the side wall of the fixed mold 6 and cooperate with the fixing structure in the second mounting groove 5 to achieve circumferential positioning of the fixed mold 6, preventing the fixed mold 6 from deflecting due to uneven changes in material during manufacturing; suitable for molding products with symmetrical cross sections.

[0026] In some technical solutions of this utility model, a positioning groove 4 coaxial with the second mounting groove 5 is provided on the side wall of the second positioning seat 2, and the fixed mold 6 is embedded in the positioning groove 4. The positioning groove 4 provides a radial reference for the fixed mold 6, ensuring its coaxiality with the moving mold 9. The fixed mold 6 is embedded in the positioning groove 4 of the second positioning seat 2. The positioning groove 4 is coaxial with the second mounting groove 5 and is fixed by mechanical clamping or bolts. The double positioning (mounting groove + positioning groove 4) improves the installation accuracy of the fixed mold 6; it is suitable for high-precision thin-walled part forming.

[0027] In some technical solutions of this utility model, a first air supply channel 7 is provided inside the positioning post 3, and a second air supply channel communicating with the first air supply channel 7 is provided on the second screw structure 8. An air inlet 11 communicating with the first air supply channel 7 is provided on the outer wall of the positioning post 3. The first air supply channel 7 is connected to an external air source through the air inlet 11. The gas enters the contact surface between the moving mold 9 and the fixed mold 6 through the second air supply channel, reducing mold wear and extending service life. The gas film formed on the contact surface between the moving mold 9 and the fixed mold 6 can assist in demolding and reduce scratches on the product surface.

[0028] In some technical solutions of this utility model, there are multiple first mounting slots and multiple second mounting slots 5, which are respectively placed on the side wall of the first positioning seat 1 or the second positioning seat 2. The above structure is used to install multiple mold positioning fixtures to realize multi-station parallel processing, improve production efficiency. Multiple mounting slots are provided on the first / second positioning seat 2, which can simultaneously install multiple sets of moving molds 9 and fixed molds 6, and are suitable for batch production of multi-specification products; quick model change can also be achieved by switching different mounting slots.

[0029] In some technical solutions of this utility model, a number of fixing holes are provided on the side wall of the first positioning seat 1 or the second positioning seat 2. The tooling is fixed to the worktable or drawing machine tool 10 by bolts or clamps. The fixing holes (such as threaded holes or slots) are set on the side wall of the positioning seat for connection with external equipment (such as machine tools), which enhances the overall rigidity of the tooling and adapts to the installation requirements of different processing equipment.

[0030] A mold assembly includes a mold mounting and positioning fixture and a drawing machine 10. A first positioning seat 1 is fixed to the output end of the drawing machine 10, and a second positioning seat 2 is fixed to the worktable of the drawing machine. The linear power of the drawing machine 10 drives the moving mold 9 to move relative to the fixed mold 6, realizing continuous or intermittent forming of the workpiece. The first positioning seat 1 is fixed to the output end of the drawing machine 10 (e.g., a hydraulic cylinder), and the second positioning seat 2 is fixed to the worktable. The machine tool drives the moving mold 9 to move towards the fixed mold 6 to complete the material drawing or extrusion. The above design integrates the fixture and the machine tool, simplifying the production line layout. It is also suitable for precision drawing forming of materials such as metals and plastics.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
