The LD component mounting groove 41 is provided from the positioning platform 4 to the middle, and the other end of the inner push molding rod 32 is provided with a pin molding groove 322; the middle of the upper end of the extrusion molding component 3 is provided with a positioning molding column 33 extending to the middle of the LD component mounting groove 41, and the upper end of the positioning molding column 33 is provided with a plurality of pin positioning grooves 331, and each of the pin positioning grooves 331 corresponds to one of the pin molding grooves 322; the pin positioning grooves 331 and the pin molding grooves 322 cooperate with each other during operation to complete the LD component pin molding.
[0023] The lower end of the outer frame 1 is provided with a forming push cylinder 2, and the extrusion molding component 3 is also provided with a push frame 34 and a push block 35. The push block 35 is connected to the push frame 34 by screws, and the lower end of the push frame 34 is connected to the output end of the forming push cylinder 2. Several push cam structures 31 are integrally formed at the top of the push frame 34, and the lower end of the positioning molding column 33 is threadedly connected to the push block 35.
[0024] An oblique sliding hole 321 is provided at one end of the inner push forming rod 32, a pushing matching groove 311 is provided at the top end of the pushing cam structure 31, connecting rods are fixedly provided on both sides of the upper end of the pushing matching groove 311, a cam 312 is provided in the middle of the connecting rod, and the cam 312 is slidably fitted in the oblique sliding hole 321.
[0025] The inner diameter of the LD element mounting groove 41 is also provided with an LD element positioning block 411, and the outer diameter of the LD element is provided with a positioning groove that matches the shape and position of the LD element positioning block 411.

[0027] In summary, the specific implementation of the utility model is as follows: when performing pin molding of a multi-pin LD component, firstly, the LD component is inserted into the LD component mounting groove 41 of the molding positioning platform 4, and the positioning groove on its outer diameter cooperates with the LD component positioning block 411 to achieve foolproof positioning, ensuring that the pin is accurately aligned with the pin positioning groove 331 of the positioning molding column 33;
[0028] Start the molding push cylinder 2, and the thrust generated at the output end of the cylinder is transmitted to the push cam structure 31 through the push frame 34. The push cam structure 31, with the cooperation of the inclined sliding hole 321, the pushing matching groove 311 and the cam 312, makes the inner push molding rod 32 slide smoothly toward the LD component installation groove 41 at the center of the molding positioning platform 4.

Finally, take out the LD component after the pin molding, and then proceed to the next step.
