DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] As Figures 1-5 shown, a large-scale Sichuan-shaped logistics tray injection mold with an internal inclined ejector mechanism includes an upper template 1 and a lower template 2. A forming cavity 3 is provided between the upper template 1 and the lower template 2. A forming groove 4 is recessed inwardly on the lower template 2. A number of detachable inserts 5 protrude in the forming groove 4. The forming cavity 3 consists of a tray bottom forming part 6 provided on the upper surfaces of the number of detachable inserts 5 and a tray wall forming part 7 provided on the inner wall of the forming groove 4. Side groove body forming mechanisms 8 are symmetrically arranged on the left and right sides of the lower template 2. A hollow partition forming mechanism 9 that communicates the left and right sides of the product is provided at the center of the lower template 2.

[0027] In the present utility model, the molding cavity between the upper template 1 and the lower template 2 can be injection molded to form a Sichuan-shaped logistics tray. The hollow partition forming mechanism 9 at the center of the lower template 2 can form a partition with a connecting groove capable of communicating the left and right chambers of the logistics tray in the middle of the forming groove, eliminating the need for post-processing and thus improving the production efficiency of the Sichuan-shaped logistics tray. The side groove forming mechanism 8 can form side grooves on the left and right sides of the Sichuan-shaped logistics tray, eliminating the need for post-processing and thus further improving the production efficiency.

[0028] Specifically, the hollow partition forming mechanism 9 includes a partition forming part 10 arranged at the middle position of the forming groove 4. Two first connecting groove forming blocks 11 protruding into the partition forming part 10 are arranged in the forming groove 4. Two ejector pins 12 are symmetrically arranged on both sides of the first connecting groove forming block 11. A second connecting groove forming block 13 abutted against the side wall of the first connecting groove forming block 11 is fixedly connected to the inner end of the ejector pin 12. It also includes a double ejector pin cross-ejecting assembly connected to the ejector pin 12. The partition forming part 10 at the middle position of the forming groove 4 can form a partition at the middle position of the Sichuan-shaped logistics tray. The first connecting groove forming block 11 and the second connecting groove forming block 13 on the ejector pin 12 can form a connecting groove capable of communicating the left and right chambers of the logistics tray on the partition. The double ejector pin cross-ejecting assembly can separate the ejector pins and the partition while the product is demolded, eliminating the need for an additional core-pulling mechanism.

[0029] Specifically, the double ejector pin cross-ejecting assembly includes two sets of X-shaped cross-ejecting rods. The bottom ends of the X-shaped cross-ejecting rods are hinged to a top plate 14 arranged on the lower side of the lower template 2. The top ends of the X-shaped cross-ejecting rods are respectively connected to the two ejector pins 12. The X-shaped cross-ejecting rod includes two cross-arranged ejector rods 15. The top ends of the two ejector rods 15 are respectively connected to the two ejector pins 12 on both sides of the first connecting groove forming block 11. When the top plate moves upward, it can apply an obliquely upward thrust to the two ejector pins 12 on both sides of the first connecting groove forming block 11 through the two cross-arranged ejector rods 15, so that both ejector pins can move upward and move away from the first connecting groove forming block in the horizontal direction, thus realizing the core-pulling of the ejector pins. It can also apply a thrust to the position of the connecting groove of the partition to make the force on the product more uniform when it is ejected.

[0030] Specifically, a guide rod 16 parallel to the ejector rod 15 is also fixedly connected to the bottom of the ejector pin 12. The guide rod 16 can guide the ejector pin during movement.

[0031] Specifically, the side groove body forming mechanism 8 includes a side insert block 17 and a translation component 18 connected to the side insert block 17. Two side groove body forming blocks 19 are fixedly connected to the inner end of the side insert block 17 and horizontally inserted into the tray wall forming part 7. The side groove body forming blocks 19 on the side insert block 17 are inserted into the tray wall forming part 7, which can form side groove bodies on the side walls of the product during product injection molding. After the product is injection molded, the translation component can drive the side insert block and the side groove body forming blocks to translate away from the molding cavity, so that the side groove body forming blocks can be separated from the product. The translation component 18 includes a translation driver 20 fixed on the lower template 2, and the end of the output shaft of the translation driver 20 is fixedly connected to the side insert block 17. The translation driver can drive the side insert block to reciprocate horizontally.

[0032] Those skilled in the art should understand that the translation driver can be an oil cylinder, a cylinder or a linear motor, etc.

[0033] Preferably, a side insert block limiting structure is further provided on the lower template 2. The side insert block limiting structure includes two guiding seats 21 fixed on the lower template 2 and respectively arranged on both sides of the translation driver 20. A guiding slider 23 inserted into the guiding chute 22 on the guiding seat 21 is fixedly connected to the side insert block 17. The cross sections of the guiding chute 22 and the guiding slider 23 are in an inverted T shape. The guiding chute on the guiding seat cooperates with the guiding slider on the side insert block 17 to limit the side insert block when the side insert block moves.

[0034] The working principle of the present utility model is as follows: The molding cavity between the upper template 1 and the lower template 2 can injection mold a Sichuan-shaped logistics tray. The hollow partition forming mechanism 9 at the center of the lower template 2 can form a partition with a connecting groove that can communicate the left and right chambers of the logistics tray in the middle of the molding groove, without the need for later processing, thus improving the production efficiency of the Sichuan-shaped logistics tray. The side groove body forming mechanism 8 can form side groove bodies on the left and right sides of the Sichuan-shaped logistics tray, without the need for later processing, thus further improving the production efficiency;

[0035] The partition forming part 10 at the middle position of the molding groove 4 can form a partition at the middle position of the Sichuan-shaped logistics tray. The first connecting groove forming block 11 and the second connecting groove forming block 13 on the inclined ejector block 12 can form a connecting groove that can communicate the left and right chambers of the logistics tray on the partition. The double inclined ejector block cross-ejecting component can separate the inclined ejector block from the partition while the product is demolded. Without an additional core-pulling mechanism, when the top plate moves upward, it can apply an obliquely upward thrust to the two inclined ejector blocks 12 on both sides of the first connecting groove forming block 11 through two cross-set inclined ejector rods 15 respectively, so that both inclined ejector blocks can move away from the first connecting groove forming block in the horizontal direction while moving upward, thereby realizing the core-pulling of the inclined ejector block, and can also apply a thrust to the connecting groove position of the partition to make the force on the product more uniform when it is ejected. The guiding rod 16 can guide the inclined ejector block when it moves;

[0036] The side groove body forming block 19 on the side insert block 17 is inserted into the tray wall forming part 7, and a side groove body can be formed on the side wall of the product during product injection molding. After the product is injection molded, the translation component can drive the side insert block and the side groove body forming block to translate away from the molding cavity, so that the side groove body forming block can be separated from the product. The translation driver can drive the side insert block to reciprocate horizontally, and the guiding chute on the guiding seat cooperates with the guiding slider on the side insert block 17 to limit the side insert block when it moves.
