Detailed Implementation
[0026] like Figures 1-5As shown, an injection molding mechanism for metal inserts of electric vehicle saddle floor includes an upper template 1 and a lower template 2. A saddle floor molding cavity 3 is provided between the upper template 1 and the lower template 2. An insert-type saddle floor latch plate molding assembly 4 and an adapter molding structure 5 are provided between the upper template 1 and the lower template 2. The insert-type saddle floor latch plate molding assembly 4 is located at the tail of the saddle floor molding cavity 3. The adapter molding structure 5 and the insert-type saddle floor latch plate molding assembly 4 are respectively located on the front and rear sides of the saddle floor molding cavity 3. The upper template 1 is also provided with a saddle floor bottom reinforcing rib molding structure 6, and the lower template 2 is also provided with a saddle floor top annular rib molding structure 7.
[0027] In this invention, an insert-type locking plate forming assembly is provided at the tail of the saddle floor forming cavity, and is placed on the front and rear sides separately from the adapter forming structure. Together with the bottom reinforcing rib and the top annular plate rib forming structure, a multi-area independent forming system is formed. The insert-type saddle floor locking plate forming assembly 4 in this design can be replaced independently, which solves the problem of high maintenance cost of traditional integrated molds. At the same time, the bottom reinforcing rib forming structure 6 and the top annular plate rib forming structure 7 of the saddle floor can improve the structural strength of the produced saddle floor.
[0028] Specifically, the insert-type saddle floor locking plate forming assembly 4 includes a first metal insert 8 embedded on the upper template 1 and a second metal insert 9 embedded on the lower template 2, with a locking plate forming structure provided between the first metal insert 8 and the second metal insert 9. The insert-type locking plate forming assembly adopts a design where the first metal insert is embedded in the upper template and the second metal insert is embedded in the lower template, forming a locking plate forming structure between them. This split insert structure allows damaged parts at the locking plate forming position to be individually disassembled and replaced, avoiding the need to replace the entire mold due to partial damage, significantly reducing maintenance costs, while ensuring the forming accuracy of the locking plate.
[0029] Specifically, the snap-on plate forming structure includes a snap-on plate forming groove 10 recessed inward on the second metal insert 9 and a snap-on plate forming block 11 protruding on the first metal insert 8. The snap-on plate forming structure, through the interaction of the snap-on plate forming groove on the second metal insert and the snap-on plate forming block on the first metal insert, forms a recessed and convex fitting forming space. This design ensures that the snap-on plate structure has a clear outline and accurate dimensions during injection molding, avoiding poor snap-on plate forming due to mold structure defects and improving the product qualification rate.
[0030] Specifically, the locking plate forming groove 10 is further recessed on both sides by bolt mounting post forming grooves 12, and the locking plate forming block 11 has bolt mounting post threaded hole forming rods 13 on both sides that are inserted into the bolt mounting post forming grooves 12. The bolt mounting post forming grooves on both sides of the locking plate forming groove cooperate with the bolt mounting post threaded hole forming rods on both sides of the locking plate forming block to achieve synchronous forming of the bolt mounting structure. This design directly forms the bolt mounting posts and their threaded holes during the injection molding process, avoiding subsequent secondary processing and improving production efficiency. At the same time, the reinforcing rib forming grooves ensure the structural strength of the mounting posts.
[0031] Specifically, the adapter forming structure 5 includes an adapter forming groove 14 recessed inward on the lower template 2 and an adapter forming block 15 protruding on the upper template 1. The adapter forming block 15 is inserted into the adapter forming groove 14. The adapter forming structure achieves precise forming of the adapter position through the cooperation of the adapter forming groove of the lower template and the adapter forming block of the upper template. This design makes the adapter and the saddle floor integrally formed, ensuring the connection strength and assembly accuracy of the two, and avoiding the assembly errors of traditional split structures.
[0032] Specifically, the saddle floor bottom reinforcing rib forming structure 6 includes several inwardly recessed first reinforcing rib forming grooves 16 and several inwardly recessed second reinforcing rib forming grooves 17 on the upper template 1. The saddle floor bottom reinforcing rib forming structure is formed by several horizontal first reinforcing rib forming grooves and vertical second reinforcing rib forming grooves intersecting in a grid pattern and interconnected, forming a grid-like reinforcing rib on the bottom surface of the saddle floor. This design enhances the compressive strength and deformation resistance of the saddle floor bottom surface, improving the overall structural stability of the product.
[0033] Specifically, the No. 1 reinforcing rib forming groove 16 is arranged horizontally, and the No. 2 reinforcing rib forming groove 17 is arranged horizontally and vertically. Several No. 1 reinforcing rib forming grooves 16 and No. 2 reinforcing rib forming grooves 17 are arranged in a grid pattern, and the No. 1 reinforcing rib forming grooves 16 and No. 2 reinforcing rib forming grooves 17 are interconnected. The horizontal arrangement of the No. 1 reinforcing rib forming grooves and the vertical arrangement of the No. 2 reinforcing rib forming grooves, forming a grid pattern and being interconnected, creates a crisscrossing support system for the bottom reinforcing ribs. This structure further optimizes the stress distribution of the reinforcing ribs, improves the load-bearing capacity of the saddle floor bottom surface in different directions, and reduces the risk of deformation.
[0034] Specifically, the annular reinforcing rib forming structure 7 on the top surface of the saddle floor includes an annular reinforcing rib forming groove 18 recessed inward on the lower template 2. Through the annular reinforcing rib forming groove of the lower template, the annular reinforcing rib forming structure on the top surface of the saddle floor forms annular reinforcing ribs. This design enhances the structural strength of the top surface of the saddle floor, especially forming annular support in the edge area, improving the product's impact resistance and durability.
[0035] Preferably, a reinforcing rib forming groove 19 is also provided circumferentially on the inner wall of the bolt mounting post forming groove 12. The reinforcing rib forming groove circumferentially provided on the inner wall of the bolt mounting post forming groove forms a reinforcing rib on the surface of the bolt mounting post. This design increases the structural strength of the bolt mounting post, avoids the post from breaking due to stress during bolt installation and use, and improves product reliability.
[0036] Specifically, the first metal insert 8 is detachably fixed to the upper template 1 by several bolts, and the second metal insert 9 is detachably fixed to the lower template 2 by several bolts. The first and second metal inserts are detachably fixed to the upper and lower templates respectively by bolts, enabling quick assembly and disassembly of the inserts. This design makes the replacement of the locking plate forming assembly more convenient, shortens maintenance time, and improves equipment utilization. At the same time, the bolt connection ensures that the inserts are firmly installed, guaranteeing forming accuracy.
[0037] The working principle of this utility model is as follows: by setting an insert-type locking plate forming component at the tail of the saddle floor forming cavity, and placing it on the front and rear sides separately from the adapter forming structure, and cooperating with the bottom reinforcing rib and the top annular plate rib forming structure, a multi-area independent forming system is formed. The insert-type saddle floor locking plate forming component 4 in this design can be replaced independently, which solves the problem of high maintenance cost of traditional integrated mold. At the same time, the bottom reinforcing rib forming structure 6 and the top annular plate rib forming structure 7 of the saddle floor can improve the structural strength of the produced saddle floor.
[0038] The insert-type snap-lock plate molding assembly adopts a design with a No. 1 metal insert embedded in the upper template and a No. 2 metal insert embedded in the lower template, forming a snap-lock plate molding structure. This split insert structure allows damaged parts at the snap-lock plate molding location to be disassembled and replaced individually, avoiding the need to replace the entire mold due to partial damage, significantly reducing maintenance costs, while ensuring the molding accuracy of the snap-lock plate. The snap-lock plate molding structure forms a concave-convex fitting molding space through the snap-lock plate molding groove on the No. 2 metal insert and the snap-lock plate molding block on the No. 1 metal insert. This design ensures that the snap-lock plate structure has a clear outline and accurate dimensions during injection molding, avoiding poor snap-lock plate molding due to mold structure defects, and improving the product qualification rate. The bolt mounting post molding grooves on both sides of the snap-lock plate molding groove cooperate with the bolt mounting post internal thread hole molding rods on both sides of the snap-lock plate molding block to achieve synchronous molding of the bolt mounting structure. This design directly forms the bolt mounting posts and their internal thread holes during injection molding, avoiding subsequent secondary processing, improving production efficiency, while the reinforcing rib molding groove ensures the structural strength of the mounting posts.
[0039] The adapter forming structure achieves precise forming of the adapter position by cooperating with the adapter forming groove of the lower template and the adapter forming block of the upper template. This design makes the adapter and the saddle floor integrally formed, ensuring the connection strength and assembly accuracy of the two, and avoiding the assembly errors of the traditional split structure.
[0040] The saddle floor's bottom reinforcing rib structure consists of several horizontal No. 1 reinforcing rib forming grooves and vertical No. 2 reinforcing rib forming grooves intersecting in a grid pattern and interconnected, forming a grid-like reinforcing rib on the bottom surface of the saddle floor. This design enhances the compressive strength and deformation resistance of the bottom surface of the saddle floor, improving the overall structural stability of the product. The No. 1 reinforcing rib forming grooves are horizontally arranged, and the No. 2 reinforcing rib forming grooves are horizontally arranged, intersecting in a grid pattern and interconnected, so that the bottom reinforcing ribs form a crisscrossing support system. This structure further optimizes the stress distribution of the reinforcing ribs, improves the load-bearing capacity of the bottom surface of the saddle floor in different directions, and reduces the risk of deformation.
[0041] The annular reinforcing rib forming structure on the top surface of the saddle floor forms annular reinforcing ribs on the top surface through the annular reinforcing rib forming groove of the lower template. This design enhances the structural strength of the top surface of the saddle floor, especially forming annular support in the edge area, improving the product's impact resistance and durability. The circumferentially set mounting column reinforcing rib forming groove on the inner wall of the bolt mounting column forming groove forms reinforcing ribs on the surface of the bolt mounting column. This design increases the structural strength of the bolt mounting column, avoids the mounting column from breaking due to stress during bolt installation and use, and improves product reliability.
[0042] Metal insert No. 1 and metal insert No. 2 are detachably fixed to the upper and lower templates by bolts, enabling quick assembly and disassembly of the inserts. This design makes it easier to replace the locking plate forming components, shortens maintenance time, and improves equipment utilization. At the same time, the bolt connection ensures that the inserts are firmly installed and guarantees forming accuracy.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0044] Although this article frequently uses terms such as upper template 1, lower template 2, saddle floor forming cavity 3, insert-type saddle floor locking plate forming assembly 4, adapter forming structure 5, saddle floor bottom reinforcing rib forming structure 6, saddle floor top annular plate rib forming structure 7, first metal insert 8, second metal insert 9, locking plate forming groove 10, locking plate forming block 11, bolt mounting column forming groove 12, bolt mounting column inner screw hole forming rod 13, adapter forming groove 14, adapter forming block 15, first reinforcing rib forming groove 16, second reinforcing rib forming groove 17, annular reinforcing plate rib forming groove 18, and mounting column reinforcing rib forming groove 19, these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
