[0024] Please refer to Figures 1-5 As shown, it shows the specific structure of the first preferred embodiment of the present utility model, which is a mold for preventing clamping jamming during mold closing, capable of docking the A plate 10 and the B plate 20 of the box mold. A panel 30 is connected to the side of the A plate 10 away from the B plate 20. Accommodation cavities 40 are provided in the A plate 10 and the B plate 20, and a delay structure 50 is inserted into the accommodation cavity 40;

[0025] With the movement of the abutting end a in the delay structure 50, the mold closing sequence of the control panel 30 and the A plate 10 is controlled. When the A plate 10 and the B plate 20 are separated, through the movement of the delay structure 50 in the accommodation cavity 40, the panel 30 is first restricted and guided, and the panel 30 is separated from the A plate 10. After the panel 30 and the A plate 10 are separated, the delay structure 50 drives the A plate 10 to move and separate from the B plate 20, so as to achieve the effect of controlling the mold closing sequence.

[0026] As Figure 3 shown, exemplarily, the accommodation cavity 40 includes a first accommodation cavity 41 penetrating through the A plate 10, and a second accommodation cavity 42 recessed into the inner cavity of the B plate 20. The second accommodation cavity 42 is communicated with the first accommodation cavity 41, and a third accommodation cavity 43 provided on the side of the A plate 10 opposite to the panel 30. The third accommodation cavity 43 is communicated with the first accommodation cavity 41. The accommodation cavity 40 for accommodating the delay structure 50 is divided into three chambers, specifically the first accommodation cavity 41, the second accommodation cavity 42 and the third accommodation cavity 43. Correspondingly, the delay structure 50 located in the accommodation cavity 40 is also composed of multiple parts, and each part is movably connected to a different chamber, so that the delay structure 50 can better control the mold closing sequence.

[0027] Specifically, the first accommodation cavity 42 penetrates through the entire A plate 10, the second accommodation cavity 42 is opened on the side of the B plate 20 opposite to the A plate 10, and the second accommodation cavity 42 corresponds to the first accommodation cavity 41. When the A plate 10 and the B plate 20 are closed, the first accommodation cavity 41 is communicated with the second accommodation cavity 42, and the cross-sectional areas at the connection of the first accommodation cavity 41 and the second accommodation cavity 42 correspond. The third accommodation cavity 43 is recessed and opened on the side of the A plate 10 opposite to the panel 30, and the third accommodation cavity 43 is communicated with the top side edge of the first accommodation cavity 41.

[0028] As Figure 2As shown, the delay structure 50 includes an active rod 51 that moves in the first accommodating cavity 41. When the panel 30 and the A plate 10 are molded together, the top of the active rod 51 is parallel to the top surface of the A plate 10, and the abutting end a is located on the opposite side of the active rod 51 and the panel 30. The active rod 51 is movably inserted in the first accommodating cavity 41. When the panel 30 and the A plate 20 are separated, the active rod 51 is partially moved out of the first accommodating cavity 41 and abuts against the panel 30 to make the panel 30 separate before the A plate 20, so as to control the mold closing order.

[0029] like Figure 2 As shown, exemplarily, the delay structure 50 also includes a limiting groove 52 opened in the third accommodating cavity 43 corresponding to the movable rod 51, and a fixing block 53 is overlapped in the limiting groove 52. The fixing block 53 is placed in the third accommodating cavity 43, and the fixing block 53 is locked on the A plate 10 by screws 54. The side wall of the movable rod 51 corresponding to one end of the panel 30 is provided with a limiting groove 52. As the movable rod 51 moves in the inner cavity of the first accommodating cavity 42, the movable rod 51 contacts the panel 30, and the panel 30 moves to a preset position before the A plate 10. The bottom of the upper limiting groove 52 of the movable rod 51 contacts and squeezes the fixing block 53 locked on the A plate 10 by screws 54, and through the extrusion of the movable rod 51, the A plate 10 is pressed upward with the extrusion of the movable rod 51, thereby completing the sequential movement between the panel 30 and the A plate 10 to avoid jamming in the mold closing.

[0030] like Figure 4 As shown, exemplarily, the first accommodating chamber 41 includes an upper accommodating chamber 411 and a lower accommodating chamber 412, the upper accommodating chamber 411 is located on the opposite side of the A plate 10 and the panel 30, the cross-sectional area of ​​the upper accommodating chamber 411 is larger than that of the lower accommodating chamber 412, the movable rod 51 is tightly inserted in the lower accommodating chamber 412, and a retaining ring 511 is sleeved on one end of the movable rod 51 opposite to the panel 30, and the retaining ring 511 overlaps in the upper accommodating chamber 411. Because the panel 30 is generally located at the upper part during normal mold use, in order to prevent the movable rod 51 from moving into the second accommodating chamber 41, the first accommodating chamber 41 is divided into an upper accommodating chamber 411 and a lower accommodating chamber 412, the cross-sectional area of ​​the upper accommodating chamber 411 is larger than that of the lower accommodating chamber 412, so that the part of the movable rod 51 located in the upper accommodating chamber 411 can be overlapped in the upper accommodating chamber 411 by installing the retaining ring 511, and the upper accommodating chamber 411 is located next to the third accommodating chamber 43.

[0031] like Figure 4 As shown, illustratively, the limiting groove 52 passes through the retaining ring 511, and the fixing block 53 extends into the limiting groove 52 and is connected to the retaining ring 511. The fixing block 53 partially extends into the first accommodating cavity 41 and is inserted into the limiting groove 52 provided on the movable rod 51, so that after the movable rod 51 moves upward to a specified position, it can contact the fixing block 53 and drive the A plate 10 to move.

[0032] As shown Figure 5 Exemplarily, the delay structure 50 further includes a rubber plug 55 that is active within the second accommodation cavity 42. A connecting rod 56 is provided at the top of the rubber plug 55, and the connecting rod 56 is inserted into the connecting hole 57 on the movable rod 51. The rubber plug 55 is located within the second accommodation cavity 42 on the B plate 20, but a part of the top of the rubber plug 55 is inserted into the first accommodation cavity 41, and by the characteristics of the rubber plug 55 itself, the resistance during mold opening of the A plate 10 and the B plate 20 is increased to ensure the rationality of the mold opening sequence.

[0033] The connecting hole 57 is longer than the connecting rod 56.

[0034] In summary, the design focus of the present utility model is to control the mold opening sequence and the mold closing sequence by physical means through the design of the accommodation cavity 40 and the delay structure 50 inserted into the accommodation cavity 40, so as to avoid the jamming or errors that occur in the traditional rubber plug for controlling the mold opening and closing sequences due to high temperature and the increase in the service time.

[0035] The above description is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
