Description

Technical Field

[0001] This utility model relates to the field of solder bar forming mold technology, specifically a solder bar forming mold for quick demolding. Background Technology

[0002] Solder bar forming molds are precision tools specifically designed to process molten solder into standard rod-shaped products. The upper and lower molds close to form a predetermined cavity, into which molten solder is injected and cooled to set before rapid demolding. The precise connection between the mold core and the cavity ensures that parameters such as the solder bar diameter and roundness meet industry standards. The integrated design of the push plate, guide pillars, and ejection mechanism allows for automatic detachment of the finished product after mold opening. Multiple solder bars can be produced in a single cycle. The built-in water cooling system and positioning ring effectively reduce solder oxidation and dimensional deviations, ensuring the product's conductivity and mechanical strength. This device is widely used in fields such as electronic soldering and chemical catalysis, and is a core piece of equipment for achieving standardized production in the deep processing industry chain of solder materials.

[0003] Traditional solder bar molding molds require manual tapping of the outside of the mold with an aluminum rod to release the solder bar formed inside. This manual unloading reduces the efficiency of the molding mold and poses certain risks. Furthermore, most traditional molds are integral structures, requiring disassembly for cleaning and maintenance, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release solder bar forming mold to solve the problems mentioned in the background art, such as the reduced working efficiency of the forming mold due to manual unloading, the inherent dangers of manual unloading, and the inconvenience of cleaning and maintenance due to the need to disassemble the entire device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release solder bar forming mold, comprising: a base plate, a connecting block and a mold core fixing block, wherein the upper end of the base plate is provided with guide post holes;

[0006] It also includes a first support plate and a positioning through hole. The upper end of the first support plate is provided with a stripper plate. The upper end of the stripper plate is fixedly connected with a push plate guide post. The upper end of the push plate guide post is provided with a forming mold core base. The upper end of the forming mold core base is provided with a mold core head, and the mold core head is provided with a mold core seat inside. The upper end of the first support plate is provided with a cavity plate, and the upper end of the cavity plate is provided with a cavity fixing plate.

[0007] The upper end of the cavity fixing plate is provided with an intermediate plate, and the cavity plate, cavity fixing plate and intermediate plate are connected to the positioning through hole by the mold core fixing block.

[0008] The middle plate has a positioning plate at its upper end, and a second support plate at its upper end. Drainage holes are provided on the middle plate, the positioning plate, and the second support plate.

[0009] Both the cavity plate and the cavity fixing plate have snap-fit ​​grooves at their upper ends, and the snap-fit ​​grooves are snap-fitted to the forming mold core base.

[0010] The base plate and the first support plate are connected by a mold core fixing block and a guide post hole.

[0011] The connecting block has a top cover fixing plate at its upper end, and the top cover fixing plate has a top plate at its upper end.

[0012] The base of the forming mold core is made of cemented carbide, and the mold core fixing block is made of cold work die steel.

[0013] This utility model has at least the following beneficial effects:

[0014] The mold core fixing block is snapped into the base plate and the first support plate to fix the bottom of the mold. The mold core fixing block is also snapped into the cavity plate, the cavity fixing plate and the intermediate plate, which facilitates quick disassembly of the device. The mold is divided into independent modules, and each module is fixed by quick-release pins to ensure that the main mold body does not need to be disassembled during cleaning, avoiding positioning deviations caused by frequent disassembly of the main body for maintenance. The mold core uses a double spiral cooling water channel. The top plate presses down, the push plate guide post pushes, and the stripper plate pushes out the solder bar. The solder bar slides out along the drain hole. Automatic demolding reduces manual workload and improves work efficiency. The drain hole drains molten solder and provides cooling water channels for cooling the mold to be formed. After forming and demolding, the formed solder bar slides out after demolding. Each mold core seat can form multiple solder bars at a time, and different sizes of mold core seats can be replaced according to usage requirements to form solder bars of different sizes, improving the applicability of the device.

When injection molding is required using this device, injection molding liquid is poured in through the through hole in the middle of the top plate 20. The injection molding liquid enters the mold core seat 10, and under the precise connection between the mold core seat 10 and the cavity... The solder bar is formed into a predetermined shape. Cooling water channels are arranged through the drain hole 17 to rapidly cool the injection molding liquid and solidify it into a solder bar. After the solder bar is cooled and solidified, the top plate 20 presses down, driving the push plate guide post 7 to move downward.

The process does not require manual assistance and realizes the automatic sliding out of the solder bar. The slid-out solder bar is collected in a designated container, and the mold can continue to perform the next injection molding and demolding operation, realizing efficient production.
