DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below with the help of drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] A mold structure for multidirectional demolding, as shown in Figures 1-8 , comprising a spring block seat 1, a spring block head 2, a slider block 3, a slider 4 and a guide assembly 5, the guide assembly 5 is arranged on the upper die, the spring block seat 1 is slidably connected with the guide assembly 5, and the guide assembly 5 is used for guiding the spring block seat 1 to move obliquely; the spring block head 2 is horizontally slidably connected with the spring block seat 1 through a connecting assembly, the spring block head 2 is provided with a slider guide groove, the slider 4 is arranged in the slider guide groove, and the slider 4 is guided to move through the slider guide groove; the slider block 3 is arranged on the upper die, and the slider 4 is slidably connected with the slider block 3.

[0027] In an embodiment, as shown in Figures 1-8 , the spring block seat 1 is provided with a first guide limiting hole 11, a first limiting pull rod 12 is slidably arranged in the first guide limiting hole 11 and connected with the upper die, the first limiting pull rod 12 is provided with a first spring 13, and the first spring 13 provides an oblique thrust force for the spring block seat 1. Specifically, the first spring 13 is sleeved on the first limiting pull rod 12, and the two ends of the first spring 13 act on the upper die and the spring block seat 1. When the mold is opened, the upper die is separated from the spring block seat 1, the spring block seat 1 is guided to move to the right through the guide assembly 5, and the distance between the spring block seat 1 is limited through the first limiting pull rod 12.

[0028] In an embodiment, as shown in Figures 1-8As shown, the connecting assembly includes a second limiting pull rod 61 and a second spring 62. A second guide limiting hole 14 is horizontally arranged on the elastic block seat 1. The second limiting pull rod 61 is slidingly arranged in the second guide limiting hole 14 and connected with the elastic block head 2. The second spring 62 is arranged on the second limiting pull rod 61 and acts on the elastic block seat 1 and the elastic block head 2. The first limiting pull rod 61 limits the maximum distance between the elastic block head 2 and the elastic block seat 1. When the distance is reached, the elastic block head 2 and the elastic block seat 1 move synchronously. The second spring 62 provides a leftward thrust to the elastic block head 2.

[0029] In an embodiment, as shown in Figures 1-8 A T-shaped guide rail 32 is arranged on the sliding block seat 3, and a first guide groove 41 is arranged on the sliding block 4. The T-shaped guide rail 32 and the first guide groove 41 cooperate to provide a driving force for the sliding block 4 to move along the sliding block guide groove, so that the sliding block 4 is first separated from the reverse buckling position.

[0030] In an embodiment, as shown in Figures 1-8 First guide strips 15 are arranged on both sides of the elastic block seat 1, and second guide grooves 21 are arranged on both sides of the elastic block head 2 to cooperate with the first guide strips 15. The first guide strips 15 and the second guide grooves 21 cooperate to assist in guiding the horizontal sliding of the elastic block head 2 and the elastic block seat 1.

[0031] In an embodiment, as shown in Figures 1-8 A elastic block head stopper 7 is arranged on the upper die. Specifically, an opening is arranged on the elastic block head 2. When the mold is closed, the elastic block head 2 is tightly attached to the upper die. At this time, the elastic block head stopper 7 is inserted into the opening. In the pre-opening step, the stopper 7 is still in the opening and is used to limit the horizontal movement of the elastic block head 2. When the elastic block head 2 reaches a certain distance from the upper die, the elastic block head stopper 7 is separated from the opening. At this time, the mold continues to open, and the elastic block head 2 can move to the right.

[0032] In an embodiment, as shown in Figures 1-8 The guide assembly 5 includes a main guide seat 51 and a side guide seat 52. The main guide seat 51 is slidingly connected to the rear part of the elastic block seat 1, and the side guide seat 52 is slidingly connected to both sides of the elastic block seat 1.

[0033] In the above embodiment, as shown in Figures 1-8 First guide portions 511 are arranged on both sides of the main guide seat 51, and third guide grooves 16 are arranged on the elastic block seat 1 to cooperate with the first guide portions 511. The first guide portions 511 and the third guide grooves 16 are both arranged obliquely, thereby realizing horizontal movement during mold opening.

[0034] In the above embodiment, as shown in Figures 1-8 A fourth guide groove 521 is arranged on the side guide seat 52, and second guide strips 17 are arranged on both sides of the elastic block seat 1 to cooperate with the fourth guide groove 521. Similarly, the second guide strips 17 and the fourth guide groove 521 are both arranged obliquely.

[0035] In the above embodiment, as shown in Figures 1-8 Two sides of the elastic block seat 1 are recessed with installation grooves 18, and the second guide bar 17 is installed in the installation grooves 18; specifically, the second guide bar 17 is fastened with the elastic block seat 1 through screws.

[0036] In use, as shown in Figures 1-8 The elastic block seat 3 is provided with an elastic block pull hook 18, and the lower die is provided with a lower die pull hook 8; when the die is opened, the lower die pull hook 8 and the elastic block pull hook 18 provide a downward traction force for the elastic block seat 1, so that the elastic block seat 1 is separated from the upper die. During the opening process, the elastic block head 2 is kept stationary due to the blockage of the elastic block head block 7 and the leftward thrust of the second spring 62, the elastic block seat 1 moves to the right, at the same time, the slide block seat 3 drives the slide block 4 to move along the slide block guide groove, so that the slide block 4 is separated from the reverse buckling structure first; when the distance between the elastic block seat 1 and the elastic block head 2 reaches the limiting distance, the elastic block seat 1 drives the elastic block head 2 to move to the right synchronously through the second limiting pull rod 61, and the elastic block head 2 is separated from the reverse buckling position.

[0037] The above is only a preferred embodiment of the utility model, and is not used to limit the implementation range of the utility model; if the utility model is modified or replaced equivalently without departing from the spirit and range of the utility model, all should be covered in the protection range of the utility model claim.
