Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically a multi-directional die for forming machine housings. Background Technology

[0002] With the rapid development of industries such as electronics, power tools, and automobiles, the functions and structures of housings are becoming increasingly complex. For example, power tool housings often have outwardly inclined connecting parts and inwardly recessed connecting grooves. Electronic equipment housings are designed with multiple side holes for heat dissipation, wiring, etc., and some precision housings also have special structures such as staggered side buckles.

[0003] In existing technologies, traditional molds either cannot achieve complete molding when facing multi-directional side holes and undercut structures on the housing, or require multiple independent demolding mechanisms. This approach not only leads to a significant increase in mold size but also easily causes problems such as core pulling interference and poor synchronization. Moreover, when the independent mechanisms work together to demold, they are very likely to cause scratches and deformation on the surface of the housing, affecting product quality. Therefore, a multi-directional mold for housing molding is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a multi-directional mold for forming machine casing, including a base, and an auxiliary forming mechanism is provided on the top of the base;

[0006] The auxiliary molding mechanism includes a mounting groove, with mold blocks slidably connected to the inner side of each mounting groove. Each mold block has a molding groove on its inner sidewall. A mounting frame is fixedly connected to the middle of the outer sidewall of each mold block. A pressure-applying inclined block is fixedly connected to the inner side of each mounting frame. An L-shaped plate is fixedly connected to both ends of the outer sidewall of each mold block away from the mounting frame. A limit rod is slidably connected through the middle of each L-shaped plate. The limit rod is fixedly connected to the middle of the outer sidewall of the positioning column. A pressing block is provided at the top of the inner side of each mounting frame.

[0007] As a preferred embodiment of this utility model, the positioning columns are fixedly connected to the four corners of the top wall of the base, and each positioning column has a positioning hole in the middle of its top wall.

[0008] As a preferred embodiment of this utility model, the top of the positioning column is slidably connected to a mold top plate, and the mold top plate is slidably connected to a lower pressure plate via a telescopic rod.

[0010] As a preferred embodiment of this utility model, the bottom of the lower pressure block and the top of the pressure-applying inclined block are both inclined, and the lower pressure block is in clearance fit with the inner side wall of the mounting frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. This type of multi-directional mold for housing forming uses multiple sets of sliding mold blocks in conjunction with forming grooves to adapt to the forming requirements of housings with multi-directional side structures. At the same time, by utilizing the sliding cooperation between guide pillars and guide grooves, the positioning effect of positioning pillars, and the spring-assisted reset of mold blocks, the mold block closing gap can be precisely controlled, effectively ensuring the dimensional accuracy and structural integrity of the housing product, and avoiding the side structure defects caused by unidirectional forming in traditional molds.

[0016] 2. This type of multi-directional mold for housing forming can simultaneously drive multiple sets of mold blocks to complete the mold closing and demolding actions by driving the linear motion of the lower pressure plate through an electric push rod, without the need for an additional independent drive mechanism; and during demolding, the spring can assist the mold blocks to automatically reset, reducing manual intervention steps, which not only reduces the complexity of mold operation, but also improves the production continuity and single-processing efficiency of housing forming.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-5 As shown, this utility model provides a multi-directional mold for forming machine housings, including a base 1, and an auxiliary forming mechanism 2 is provided on the top of the base 1;

[0026] The auxiliary molding mechanism 2 includes a mounting groove 4, which provides space for the installation of mold blocks 7. The mold blocks 7 can also slide within the mounting groove 4 for mold closing or demolding. Mold blocks 7 are slidably connected to the inner side of the mounting groove 4. Each mold block 7 has a molding groove 10 on its inner wall. The molding grooves 10 on the inner walls of the four sets of mold blocks 7 can be assembled to form a complete housing molding groove 10. A mounting frame 8 is fixedly connected to the middle of the outer wall of each mold block 7. A pressure-applying inclined block 9 is fixedly connected to the inner side of each mounting frame 8. The pressure-applying inclined block 9 cooperates with the lower pressure block 15 to provide sliding space for the mold blocks 7 within the mounting groove 4. The outer side wall of the mold block 7 is fixedly connected to both ends of the mounting frame 8. The middle of the L-shaped plate 11 is slidably connected to the limiting rod 12. The limiting rod 12 can limit the L-shaped plate 11 and give the mold block 7 the ability to reset through the spring 14. The limiting rod 12 is fixedly connected to the middle of the outer side wall of the positioning column 3. The top of the inner side of the mounting frame 8 is provided with a pressing block 15. The outer end of the limiting rod 12 is fixedly connected to an anti-detachment block 13. The anti-detachment block 13 can prevent the limiting rod 12 from separating from the L-shaped plate 11. The outer periphery of the side wall of the anti-detachment block 13 near the L-shaped plate 11 is fixedly connected to a spring 14.

[0027] The positioning pins 3 are fixedly connected to the four corners of the top wall of the base 1. The positioning pins 3 are provided with positioning holes 24 in the middle of the top wall. The top of the positioning pins 3 is slidably connected to the mold top plate 20. The mold top plate 20 is slidably connected to the lower pressure plate 18 through the telescopic rod 21. The positioning pins 3 can limit the lifting and lowering of the mold top plate 20, and at the same time provide space for the installation groove 4 to be formed.

[0028] A fixing plate 17 is fixedly connected to the middle of each of the four side walls of the lower pressure plate 18. A connecting rod 16 is fixedly connected to the outer end of the bottom wall of the fixing plate 17. The bottom end of the connecting rod 16 is fixedly connected to the lower pressure block 15. The bottom of the lower pressure block 15 and the top of the pressure inclined block 9 are both inclined. The lower pressure block 15 is in clearance fit with the inner side wall of the mounting frame 8. The connecting rod 16 serves to connect the fixing plate 17 and the lower pressure block 15.

[0029] Guide posts 5 are fixedly connected to the outer side of the bottom wall of the mounting groove 4 near the positioning post 3. The guide posts 5 are slidably connected to the inner side of the guide groove 6. The guide groove 6 is respectively set on the bottom side of the mold block 7 near the positioning post 3. The inner mold 22 is fixedly connected to the middle of the top wall of the base 1. The finished product 23 is set on the outer side of the inner mold 22. The lower pressure plate 18 is fixedly connected to the output end of the electric push rod 19 in the middle of the top wall. The lower pressure plate 18 is located in the upper middle of the mold top plate 20. The electric push rod 19 provides the power source for mold closing and demolding.

[0030] Working principle: First, the positioning posts 3 at the four corners of the top wall of the base 1 are used to accurately position and install the mold top plate 20. After the electric push rod 19 fixed on the mold top plate 20 is started, its output end pushes the lower pressure plate 18 to move steadily downward along the telescopic rod 21. The lower pressure plate 18 drives the connecting rod 16 to move downward synchronously through the fixing plate 17 in the middle of the four side walls, so that the lower pressure block 15 at the bottom of the connecting rod 16 extends into the mounting frame 8 on the outside of the mold assembly 7. At this time, the inclined surface of the lower pressure block 15 fits and cooperates with the inclined surface of the pressure inclined block 9 on the inner side of the mounting frame 8, generating a lateral thrust to push the mold assembly 7 to slide inward along the guide post 5 on the bottom wall of the mounting groove 4 corresponding to the guide groove 6 at the bottom of the mold assembly 7. During the sliding process, the mold assembly... The L-shaped plate 11 on the outer side slides synchronously along the limiting rod 12 on the positioning post 3 and compresses the spring 14 until the forming groove 10 on the inner side wall of the multi-set mold block 7 and the inner mold 22 in the middle of the top wall of the base 1 surround to form a complete housing forming cavity. Then, the injection molding operation is carried out to complete the forming of the finished housing 23. After the housing is injection molded, the electric push rod 19 rotates in the reverse direction to drive the lower pressure plate 18 to move upward as a whole. The pushing force of the lower pressure block 15 on the pressure inclined block 9 disappears. The spring 14 under the limit of the anti-detachment block 13 at the outer end of the limiting rod 12 elastically resets, pushing the L-shaped plate 11 to drive the mold block 7 to slide and reset along the guide post 5 to the outside, realizing multi-directional synchronous demolding. Finally, the formed finished housing 23 can be taken out from the inner mold 22.
