Abstract
Description
Technical Field
[0001] This utility model relates to the field of fireworks production technology, specifically to a fireworks base production mold. Background Technology
[0002] The existing fireworks molds mainly use two ignition methods at the bottom: 1. **Carry-on ignition method:** This method uses four different ignition speeds: 35 seconds, 75 seconds, 6 seconds, and 200 seconds, and four different fuse lengths: 5 cm, 6.5 cm, 7.6 cm, and 30 cm. This method is prone to flameout, preventing the fireworks from igniting properly, and also requires manual ignition, increasing costs. 2. **Coil ignition method:** This method requires igniting the fuse or direct contact with the fireworks powder, making the ignition process relatively complex. Coil ignition is generally suitable for igniting single or small quantities of fireworks, cannot achieve multiple ignition modes, has a fixed ignition speed, a long ignition time, and lacks rhythm.
[0003] Existing firework base production molds suffer from limitations in the lead wire groove, insufficient volume, and inability to effectively secure the lead wire. To address these issues, a new firework base production mold is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a production mold for fireworks bases, which solves the problems of limited lead groove, insufficient volume, and inability to properly fix the lead in the background technology.

Through the limiting component, evenly distributed and continuous grooves will appear at the bottom of the serpentine mold strip, the inlet mold strip and the outlet mold strip after the mold injection is completed, which facilitates the injection of glue into the grooves to fix the lead wires.
[0009] As a further description of the above technical solution: the bottom of the infeed mold strip is fixedly connected to the top of the middle mold platform, and the bottom of the outfeed mold strip is fixedly connected to the top of the middle mold platform.
[0010] By adopting the above technical solution, the infeed mold strip and the outfeed mold strip are fixed.
[0011] As a further description of the above technical solution: both sides of the serpentine mold strip, the inlet mold strip and the outlet mold strip are provided with waist-shaped bosses, and the bottom of the waist-shaped bosses is fixedly connected to the middle mold platform.
[0012] By adopting the above technical solution, the waist-shaped boss will form a groove after demolding, which facilitates the application of glue to fix the lead wire.
[0013] As a further description of the above technical solution: the lower mold base has transverse heating holes on both the front and rear sides, and longitudinal heating holes on both the left and right sides.
[0014] By adopting the above technical solution, the horizontal heating holes and vertical heating holes can quickly and evenly provide heat to the mold, facilitating faster molding.

[0017] As a further description of the above technical solution: the serpentine mold strip is disposed on the outer side of the upper mold platform.
[0018] By adopting the above technical solution, the serpentine mold strip meanders around the outside of the upper mold platform.
[0019] As a further description of the above technical solution: the bottom of the trapezoidal boss is fixedly connected to the middle mold platform.
[0020] By adopting the above technical solution, the trapezoidal boss can easily form a groove on the base after demolding.

[0029] Reference Figure 1 , Figure 2 and Figure 3This utility model discloses a firework base production mold, including a lower mold base 1. Two middle mold platforms 2 are fixedly connected to the top of the lower mold base 1, and five upper mold platforms 3 are fixedly connected to the top of each of the two middle mold platforms 2. The lower mold base 1 serves as a basic support component, with the two middle mold platforms 2 fixedly connected to its top. Each middle mold platform 2 is further fixedly connected to the top of five upper mold platforms 3, providing the main space for the firework base forming. A serpentine mold strip 4 is fixedly connected to the center of the top of the middle mold platform 2. An inlet mold strip 5 is fixedly connected to the left side of the serpentine mold strip 4, and an outlet mold strip 6 is fixedly connected to the right side of the serpentine mold strip 4. The serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6 together form a lead wire groove for easy placement of the lead wire. Limiting components are provided on the outer sides of the serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6. Handle protrusions 10 are fixedly connected to the outer sides of all four sides of the middle mold platform 2, allowing for easy lifting and movement of the base.
[0030] Reference Figure 3 The limiting component includes trapezoidal bosses 7, and multiple trapezoidal bosses 7 are fixedly connected to the outside of the serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6. Multiple cylindrical bosses 8 are fixedly connected to the outside of the trapezoidal bosses 7. Several cylindrical bosses 8 are grouped together and connected by a connecting rod (not shown in the figure), and are fixed to the trapezoidal bosses 7 by the connecting rod. The bottom of the cylindrical bosses 8 is fixedly connected to the top of the serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6. The limiting component can make evenly distributed and through grooves appear at the bottom of the serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6 after the mold injection is completed, so as to facilitate the injection of glue inward to fix the lead wire.
[0031] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the inlet mold strip 5 is fixedly connected to the top of the middle mold base 2, and the bottom of the outlet mold strip 6 is fixedly connected to the top of the middle mold base 2, thus fixing the inlet mold strip 5 and the outlet mold strip 6. The serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6 are all provided with waist-shaped bosses 9 on both sides, and the bottom of the waist-shaped bosses 9 is fixedly connected to the middle mold base 2. After demolding, the waist-shaped bosses 9 will form grooves, facilitating glue application to fix the lead wires. The lower mold base 1 has transverse heating holes 11 extending through its front and rear sides. The lower mold base 1 also has heating holes 11 on its left and right sides. All have longitudinal heating holes 13 through them. The transverse heating holes 11 on the front and rear sides of the lower mold base 1 and the longitudinal heating holes 13 on the left and right sides can be used to introduce heating medium (such as hot oil) to provide uniform heating for the mold and facilitate molding. The lower mold base 1 has positioning holes 12 on both the front and rear ends. The positioning holes 12 are located on both sides of the transverse heating holes 11. The lower mold base 1 can be fixed through the positioning holes 12. The serpentine mold strip 4 is located on the outside of the upper mold platform 3. The bottom of the trapezoidal boss 7 is fixedly connected to the middle mold platform 2.
[0032] Working principle: The material for the fireworks base is injected into the mold cavity, which consists of a serpentine mold strip 4, an inlet mold strip 5, an outlet mold strip 6, an upper mold platform 3, a middle mold platform 2, and a lower mold base 1. Under the heat provided by the transverse heating holes 11 and the longitudinal heating holes 13, it can be rapidly molded. After the material cools, solidifies, and is demolded, the grooves formed by the waist-shaped bosses 9 on both sides of the serpentine mold strip 4, the inlet mold strip 5, and the outlet mold strip 6 allow for adhesive application to fix the lead wire. Furthermore, the grooves formed by the trapezoidal bosses 7 and several cylindrical bosses 8 allow for adhesive injection into the trapezoidal bosses 7, and the grooves formed by the through-hole cylindrical bosses 8 can fix the lower part of the lead wire.
