Detailed implementation manners
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0019] Obviously, many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0020] Please refer to Figures 1-4, the present utility model provides a Christmas ball embryo blow molding die, including a working box 1, on which a plurality of support positioning rods 6 are installed. Two symmetrical half dies 4 are slidably arranged on the plurality of support positioning rods 6. Four positioning bumps 9 that are pairwise symmetrical are fixedly connected to the center of each of the plurality of support positioning rods 6. A plurality of springs 13 are fixedly connected to one side of the inner cavity of the half die 4. One end of the plurality of springs 13 is fixedly connected to a sliding plate 12. Blow molding grooves 8 are opened on the adjacent sides of the two half dies 4. A plurality of demolding insertion rods 10 that are slidably inserted into the blow molding grooves 8 are fixedly connected to one side of the sliding plate 12. A plurality of positioning sleeves 11 that match the support positioning rods 6 are fixedly connected to the outer surface of the sliding plate 12. The plurality of support positioning rods 6 are respectively slidably inserted into the positioning sleeves 11. Grooves that match two adjacent positioning bumps 9 are opened at one end of each of the plurality of positioning sleeves 11. A material discharge port 7 is opened at the bottom of the working box 1. Two symmetrical card rails 2 are fixedly connected to both sides of the material discharge port 7 at the bottom of the working box 1. A reverse rotation mechanism is arranged on one side of the working box 1. Third rotating shafts 18 are rotatably connected to one side of each of the two half dies 4. The reverse mechanism is slidably sleeved on the outer surfaces of the two third rotating shafts 18. A connecting plate 3 is fixedly connected to one side of the working box 1. The working box 1 can be connected to the reciprocating mechanism through the connecting plate 3, so that the working box 1 can reciprocate by connecting the two card rails 2 to the sliding rails, so that the two half dies 4 can perform blow molding work after receiving materials, and the blow molding work is carried out in this process in a reciprocating manner. By starting the reverse rotation mechanism, the two half dies 4 are pushed to move away from each other on the plurality of support positioning rods 6 through the two third rotating shafts 18, so that the two half dies 4 are separated, which is convenient for placing the blow molding embryo for blow molding between the two half dies 4. Then the two half dies 4 are attached to clamp the blow molding embryo. During the clamping process, the plurality of positioning sleeves 11 will respectively fit the plurality of positioning bumps 9, so that the plurality of positioning sleeves 11 push the two sliding plates 12 to slide towards both sides of the working box 1 respectively, driving the plurality of demolding insertion rods 10 to contract inside the blow molding grooves 8 until they fit the plurality of semi-circular grooves on the blow molding grooves 8, which is convenient for blow molding work. When the blow molding is completed, by further separating the two half dies 4, the plurality of positioning bumps 9 are separated from the plurality of positioning sleeves 11, so that the two sliding plates 12 are rebounded by the plurality of springs 13 respectively, so that the plurality of demolding insertion rods 10 are respectively slidably inserted into the plurality of semi-circular grooves on the blow molding grooves 8, so as to push the blow molded Christmas ball embryos that may be attached to the blow molding grooves 8 of the two half dies 4, so that they can be separated no matter which half die 4 they adhere to.
[0021] It should be noted that the reverse rotation mechanism mentioned in the above description includes a servo motor 16. When the servo motor 16 is turned on, the second rotating shaft 15 drives a gear 17 to rotate, so that another gear 17 drives the first rotating shaft 14 to rotate, so that the two rotating blocks 20 rotate, so that the rotation of the two rotating blocks 20 drives each of the third rotating shafts 18 inside the two elliptical grooves 19 to move towards or away from each other, so as to control the distance between the two half-molds 4.
[0022] For the convenience of demolding the Christmas ball blanks, semi-circular grooves matching the plurality of demolding inserting rods 10 are provided on the plurality of blow molding grooves 8. The plurality of demolding inserting rods 10 are respectively slidably inserted into the interiors of the semi-circular grooves on the blow molding grooves 8, and the outer surface of one end of the demolding inserting rod 10 is attached to the inner wall of the semi-circular groove.
[0023] For the convenience of blow molding work and for the convenience of collecting the demolded blanks, blow molding ports 5 are opened at the tops of the two half-molds 4, and the two half-molds 4 are both slidably arranged above the material feeding port 7, and inclined surfaces are provided on the inner walls of the material feeding port 7.
[0024] Furthermore, for the convenience of clamping and blow molding work through the reciprocating movement and the relative movement towards or away from each other of the two half-molds 4, and in order to ensure the stable sliding of the two half-molds 4, a plurality of support positioning rods 6 are respectively arranged on both sides of the plurality of demolding inserting rods 10, and both sides of the sliding plate 12 are respectively attached to the two sides of the inner cavity of the half-mold 4.

However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0026] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.
[0027] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, it should also be regarded as the content disclosed by the present invention.
