[0002] The Tianzi logistics pallet is generally formed by mold injection molding. During the injection molding process of the existing Tianzi logistics pallet, the core-pulling structure needs to be used to pull the core of the channel structure of the plastic part.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-4As shown, a large-scale Tian-shaped logistics pallet mold with a secondary slider core-pulling mechanism includes a pallet molding lower mold 1 and a pallet molding upper mold 2. The pallet molding lower mold 1 is provided with a central molding panel 3, four middle molding panels 4 and eight side molding panels 5. A Tian-shaped auxiliary molding protrusion 6 is provided between the central molding panel 3 and the four middle molding panels 4. A symmetrical core-pulling assembly 7 and a core-pulling alignment slider 8 are provided between the pallet molding lower mold 1 and the pallet molding upper mold 2. The symmetrical core-pulling assembly 7 corresponds to the position of the Tian-shaped auxiliary molding protrusion 6.

[0026] In this embodiment, during the injection molding process, the tray molding lower mold 1 and the tray molding upper mold 2 are brought close to each other, and a central molding panel 3, four middle molding panels 4 and eight side molding panels 5 cooperate with the field-shaped auxiliary molding protrusion 6 to synchronously mold the field-shaped logistics pallet plastic part, and the symmetrical core pulling assembly 7 is used to assist in molding the channel structure of the plastic part. At the same time, the outer core pulling structure can be abutted and fixed by the core pulling alignment slider 8 to avoid shaking of the outer core pulling structure during injection molding, and the stability is strong. After the injection molding is completed, the mold is opened, the core pulling alignment slider 8 is first moved outward to perform side demolding, and then the symmetrical core pulling assembly 7 is moved to the outer end to perform core pulling. The secondary slider structure is used to facilitate subsequent smooth demolding, avoid jamming during demolding, and ensure the quality of the plastic part.

[0027] Combination Figure 1-4 As shown, the symmetrical core pulling assembly 7 includes two end core pulling sliders 9 arranged between the tray molding lower mold 1 and the tray molding upper mold 2, and two middle core pulling rods 10 and two side core pulling rods 11 are provided on the end core pulling sliders 9. The middle core pulling rods 10 are located in the gap formed by the central molding panel 3, the middle molding panel 4, the side molding panel 5 and the field-shaped auxiliary molding protrusion 6, and the side core pulling rods 11 are located in the gap formed by the middle molding panel 4, the side molding panel 5 and the field-shaped auxiliary molding protrusion 6.

[0028] Specifically, during injection molding, the two middle core pulling rods 10 and the two side core pulling rods 11 are used to assist in forming the channel structure of the plastic part. At the same time, the two side core pulling rods 11 can be abutted and fixed through the core pulling alignment slider 8 to avoid the two side core pulling rods 11 from shaking during injection molding. The stability is relatively strong. After the injection molding is completed, the mold is opened, and the core pulling alignment slider 8 is first moved outward to perform side demolding, and then the end core pulling slider 9 is moved to the outer end to drive the two middle core pulling rods 10 and the two side core pulling rods 11 to perform core pulling. The secondary slider structure is adopted to facilitate the subsequent smooth demolding, avoid jamming during demolding, and ensure the quality of the plastic part.

[0029] The two ends of the tray forming lower mold 1 are provided with a first limiting slide 12 , and the bottom of the end core-pulling slider 9 is provided with a first embedded slider 13 extending into the first limiting slide 12 and slidably matched with the first limiting slide 12 .

[0030] In this embodiment, when demolding, the end core pulling slider 9 is moved, and the end core pulling slider 9, the middle core pulling rod 10 and the side core pulling rod 11 are limited by the limiting action between the first embedded slider 13 and the first limiting slide 12 to improve the accuracy of core pulling.

[0031] Combination Figure 2 , Figure 3 As shown, the core-pulling alignment slider 8 includes two side alignment sliders 14 arranged between the tray forming lower mold 1 and the tray forming upper mold 2 , and the side alignment sliders 14 abut against the outer sides of the side core-pulling rods 11 .

[0032] In this embodiment, during injection molding, the side alignment slider 14 abuts against the outer side of the side core pulling rod 11 to prevent the two side core pulling rods 11 from shaking during injection molding, and the stability is relatively strong.

[0033] The tray forming lower mold 1 is provided with a second limiting slide 15 on both sides, and the bottom of the side alignment slide 14 is provided with a second embedded slide 16 extending into the second limiting slide 15 and slidably matched with the second limiting slide 15 .

[0034] In this embodiment, during the movement of the side alignment slider 14, the side alignment slider 14 is limited by the limiting action between the second embedded slider 16 and the second limiting slide 15, thereby improving the accuracy of demoulding and mold closing.

[0035] Combination Figure 2-3 As shown, the field-shaped auxiliary molding protrusion 6 includes four auxiliary molding convex blocks 17 , and a molding cavity 18 is provided in the tray molding upper mold 2 , and the positions of the auxiliary molding convex blocks 17 correspond to those of the molding cavity 18 .

[0036] In this embodiment, the molding chamber 18 is used to assist in molding a plastic part.

[0037] An alignment clamping plate 19 is disposed at the bottom of the auxiliary molding protrusion 17 , and the alignment clamping plate 19 is clamped and matched with the auxiliary molding protrusion 17 .

[0038] In this embodiment, the alignment clamping plate 19 can clamp and fix the auxiliary molding protrusion 17, and adopts a detachable structure to facilitate subsequent maintenance and replacement.

[0039] Combination Figure 1-4 As shown, an ejector plate 20 is provided below the tray forming lower mold 1 , and a plurality of straight ejector rods 21 are provided inside the ejector plate 20 .

[0040] In this embodiment, after the injection molding is completed, the mold is opened, and the ejector plate 20 is moved to drive the straight ejector rod 21 to eject the plastic part.

[0041] Combination Figure 1 As shown, an injection molding main board 22 is provided above the tray molding upper mold 2 , an injection molding main hole 23 is provided in the injection molding main board 22 , and a diverter plate 24 is provided between the injection molding main board 22 and the tray molding upper mold 2 .

[0042] In this embodiment, during injection molding, the molten material is injected into the mold cavity through the injection main hole 23 in the injection main board 22, and then diverted by the diverter plate 24 to speed up the injection molding.

[0043] The working principle of the utility model is:

[0044] During the injection molding process, the tray molding lower mold 1 and the tray molding upper mold 2 are brought close to each other, and a central molding panel 3, four middle molding panels 4 and eight side molding panels 5 cooperate with the auxiliary molding protrusions 17 to synchronously mold the field-shaped logistics tray plastic parts. The two middle core pulling rods 10 and the two side core pulling rods 11 are used to assist in molding the channel structure of the plastic parts. At the same time, the two side core pulling rods 11 can be abutted and fixed by the side alignment slider 14 to avoid the two side core pulling rods 11 from shaking during injection molding. The stability is strong. After the injection molding is completed, the mold is opened, and the side alignment slider 14 is first moved outward to perform side demoulding, and then the end core pulling slider 9 is moved to the outer end to drive the two middle core pulling rods 10 and the two side core pulling rods 11 to perform core pulling. The secondary slider structure is used to facilitate the subsequent smooth demoulding, avoid jamming during demoulding, and ensure the quality of the plastic parts.

[0045] During demoulding, the end core-pulling slider 9 is moved, and the end core-pulling slider 9, the middle core-pulling rod 10 and the side core-pulling rod 11 are limited by the limiting action between the first embedded slider 13 and the first limiting slide 12, so as to improve the accuracy of core-pulling.

[0046] During injection molding, the side alignment slider 14 abuts against the outer side of the side core pulling rod 11 to prevent the two side core pulling rods 11 from shaking during injection molding, and the stability is strong.

[0047] During the movement of the side alignment slider 14, the side alignment slider 14 is limited by the limiting action between the second embedded slider 16 and the second limiting slide 15, thereby improving the accuracy of demoulding and mold closing.

[0048] The alignment clamping plate 19 can clamp and fix the auxiliary molding protrusion 17, and adopts a detachable structure to facilitate subsequent maintenance and replacement.

[0049] After the injection molding is completed, the mold is opened, and the ejector plate 20 is moved to drive the straight ejector rod 21 to eject the plastic part.

[0050] During injection molding, the molten material is injected into the mold cavity through the injection main hole 23 in the injection main board 22, and then diverted by the diverter plate 24 to speed up the injection molding.
