Specific implementation mode

[0024] As Figures 1 - 5 shown, a vibration - sequence injection molding mechanism in a push - cart type snack cabinet mold includes an upper template 1 and a lower template 2. A forming convex block 3 protrudes on the lower template 2. A rectangular - ring - shaped snack cabinet forming cavity 4 and four sleeve installation groove forming structures 5 capable of forming sleeve installation grooves on the snack cabinet are formed between the forming convex block 3 and the upper template 1. A self - withdrawing core type sleeve buckle forming structure 6 connected to the inner side of the sleeve installation groove forming structure 5 is further provided on the upper template 1, and an inclined - top withdrawing core type sleeve clamping groove forming structure 7 is arranged on the lower template 2.

[0025] In the present utility model, the four sleeve installation groove forming structures 5 can form four sleeve installation grooves on the snack cabinet main body for the assembly of the snack cabinet and the bracket. The self - withdrawing core type sleeve buckle forming structure and the inclined - top withdrawing core type sleeve clamping groove forming structure 7 can respectively form sleeve buckles and sleeve clamping grooves on the upper and lower sides of the sleeve installation groove for fixing with the bracket during assembly, eliminating the need for later processing, reducing the production process, and improving production efficiency.

[0026] Specifically, the four sleeve installation groove forming structures 5 are distributed in a rectangle.

[0027] Specifically, the sleeve installation groove forming structure 5 includes a lower sleeve installation groove forming rod 8 provided on the lower template 2 and an upper sleeve installation groove forming rod 9 provided on the upper template 1. The top end of the lower sleeve installation groove forming rod 8 abuts against the bottom end of the upper sleeve installation groove forming rod 9. The cross-sections of both the lower sleeve installation groove forming rod 8 and the upper sleeve installation groove forming rod 9 are rectangular, and the cross-sectional area of the lower sleeve installation groove forming rod 8 is larger than that of the upper sleeve installation groove forming rod 9. The lower sleeve installation groove forming rod 8 cooperates with the upper sleeve installation groove forming rod 9 to form an upper and lower through sleeve installation groove on the snack cabinet.

[0028] Specifically, the self-core-pulling sleeve buckle forming structure 6 includes a core-pulling slider 10 slidably matched with the upper template 1 through a horizontal limiting structure. The inner end of the core-pulling slider 10 is provided with a buckle forming block 11 connected to the upper sleeve installation groove forming rod 9. A top plate 12 is arranged on the upper side of the upper template 1, and a core-pulling driving structure connected to the core-pulling slider 10 is arranged on the top plate 12. The inner end of the buckle forming block 11 on the core-pulling slider 10 abuts against the upper sleeve installation groove forming rod 9. The buckle forming block 11 can form a sleeve buckle at one time on the upper side of the sleeve installation groove during the injection molding of the snack cabinet. After the product is injection molded, when the top plate 12 moves upward, it can drive the buckle forming block 11 to automatically perform core pulling through the core-pulling driving structure, so as to facilitate the demolding of the product.

[0029] Specifically, the core-pulling driving structure includes a driving slider 13 fixed on the top plate 12. An inclined guiding chute 14 is recessed inwardly on the driving slider 13. An inclined guiding slider 15 protruding from the core-pulling slider 10 is inserted into the inclined guiding chute 14. When the top plate moves upward, it can drive the driving slider 13 to move upward. The upward movement of the driving slider 13 can drive the core-pulling slider 10 to move away from the snack cabinet forming cavity through the cooperation of the inclined guiding chute 14 and the inclined guiding slider 15, so as to realize the automatic core pulling of the buckle forming block 11.

[0030] Preferably, the horizontal limiting structure includes limiting pressing plates 16 arranged on both sides of the core-pulling slider 10. The limiting pressing plates can limit the core-pulling slider.

[0031] Specifically, the inclined ejector pin core-pulling sleeve slot forming structure 7 includes an inclined ejector pin 17. A sleeve slot forming block 18 abuting against the inner side wall of the lower sleeve installation groove forming rod 8 is fixedly connected to the side of the inclined ejector pin 17. The inclined ejector pin 17 inclines away from the lower sleeve installation groove forming rod 8. A lifting plate 19 is arranged on the lower side of the lower template 2, and the bottom of the inclined ejector pin 17 is connected to the lifting plate 19.

[0032] The sleeve slot forming block 18 on the inclined ejector pin 17 can form a sleeve slot at one time on the lower side of the sleeve installation groove during the injection molding of the snack cabinet. When the product is ejected, the upward movement of the inclined ejector pin can make the sleeve slot forming block 18 automatically disengage from the sleeve slot.

[0033] The working principle of the present utility model is as follows: The four sleeve installation groove forming structures 5 can form four sleeve installation grooves on the main body of the snack cabinet for the assembly of the snack cabinet and the bracket. The self-core-pulling sleeve buckle forming structure and the inclined ejector core-pulling sleeve slot forming structure 7 can respectively form a sleeve buckle and a sleeve slot on the upper and lower sides of the sleeve installation groove for fixing with the bracket during assembly, eliminating the need for post-processing, reducing the production process, and improving production efficiency.

[0034] The lower sleeve installation groove forming rod 8 and the upper sleeve installation groove forming rod 9 can form a vertically penetrating sleeve installation groove on the snack cabinet. The inner end of the buckle forming block 11 on the core-pulling slider 10 abuts against the upper sleeve installation groove forming rod 9. The buckle forming block 11 can form a sleeve buckle on the upper side of the sleeve installation groove in one go during the injection molding of the snack cabinet. After the product is injection molded, when the top plate 12 moves upward, it can drive the buckle forming block 11 to perform automatic core pulling through the core-pulling drive structure, facilitating product demolding. When the top plate moves upward, it can drive the drive slider 13 to move upward. The upward movement of the drive slider 13 can drive the core-pulling slider 10 to move away from the snack cabinet molding cavity through the cooperation of the inclined guide chute 14 and the inclined guide slider 15, thereby realizing the automatic core pulling of the buckle forming block 11. The limit pressing plate can limit the core-pulling slider.

[0035] The sleeve slot forming block 18 on the inclined ejector rod 17 can form a sleeve slot on the lower side of the sleeve installation groove in one go during the injection molding of the snack cabinet. When the product is ejected, the upward movement of the inclined ejector rod can make the sleeve slot forming block 18 automatically disengage from the sleeve slot.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0037] Although terms such as upper template 1, lower template 2, forming convex block 3, snack cabinet molding cavity 4, sleeve installation groove forming structure 5, self-core-pulling sleeve buckle forming structure 6, inclined ejector core-pulling sleeve slot forming structure 7, lower sleeve installation groove forming rod 8, upper sleeve installation groove forming rod 9, core-pulling slider 10, buckle forming block 11, top plate 12, drive slider 13, inclined guide chute 14, inclined guide slider 15, limit pressing plate 16, inclined ejector rod 17, sleeve slot forming block 18, and lifting plate 19 are used more frequently herein, the use of these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
