[0002] In the injection molding field, when the product outer surface has a reverse buckle structure, a slider structure is usually adopted to drive the slider to separate from the product first, and then the overall mold is opened. The movement of the slider needs a guiding structure, which is usually formed by a pressing strip fixed to the mold to form a guide groove. A guiding part is arranged on both sides of the slider to cooperate with the guide groove to realize the sliding connection between the slider and the mold. It can be seen that the space size required by the above structure is larger than the size of the slider. If the product has multiple reverse buckle structures, and the distance between the reverse buckle structures is close and the position is narrow, the space position for arranging the slider core-pulling is insufficient. At this time, if the core-pulling is increased, the mold manufacturing cost and the later maintenance cost will also increase, the structure is large, the position of the mold plate that needs to be grooved also needs to be increased, and the mold plate strength will be affected after being increased, which affects the overall stability of the mold.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and examples.

[0026] A slider guide structure for narrow area, as shown in Figures 1-7 The slider 1 is provided with a horizontal through guide groove, and the wear-resistant block 2 is in sliding connection with the guide groove; the slider 1 is provided with a guide column hole 11, and the inclined guide column 3 is arranged on the upper die; the wear-resistant block 2 comprises a fixed block 21 and a guide plate 22, the guide plate 22 is arranged on the upper surface of the fixed block 21, and the guide plate 22 is in sliding connection with the guide groove. The front end of the slider 1 is provided with a feature part 6 forming a product reverse buckle.

[0027] In an embodiment, as shown in Figures 1-7 The fixed block 21 and the guide plate 22 are connected in a T-shaped structure.

[0028] In an embodiment, as shown in Figures 1-7 The guide groove comprises a first guide part 12 and a second guide part 13, the first guide part 12 is in sliding connection with the guide plate 22, and the second guide part 13 is in sliding connection with the fixed block 21. Specifically, the slider 1 is supported on the upper surface of the guide plate 22, both sides of the first guide part 12 are provided with sliding grooves matched with the guide plate 22, the sliding grooves are matched with the guide plate 22 to limit the up-and-down movement of the slider 1 and guide the horizontal movement of the slider 1. In addition, the two side walls of the second guide part 13 are in contact with the two side walls of the fixed block 21 to realize guide cooperation. Through the above structure, a multiple guide structure is realized to ensure the reliability and stability of the movement of the slider.

[0029] In an embodiment, as shown in Figures 1-7 The upper surface of the guide plate 22 and the two side surfaces of the fixed block 21 are provided with oil grooves 23. The oil grooves 23 can store a certain amount of lubricating oil, which can reduce the wear and friction between the wear-resistant block and other parts of the die through lubrication during the use of the die. This not only helps to keep the movement of the die structure smooth, but also prolongs the service life of the die. In addition, the die is easy to generate high temperature due to friction and heat during use. High temperature can cause problems such as deformation and failure of the die, thereby affecting the quality and production efficiency of the product. The lubricating oil in the oil groove of the wear-resistant block can play a cooling role, effectively reducing the temperature of the die and ensuring the stability and precision of the die.

[0030] In an embodiment, as shown in Figures 1-7As shown, the mould further comprises a limiting block 4 arranged on the lower mould 9, which limits the opening position of the sliding block 1 by means of the limiting block 4. When the mould is opened, the sliding block 1 is driven by the inclined guide pillar 3 to move to the outside of the mould, and the sliding block is stopped by the limiting block 4 to ensure that the sliding block 1 and the wear-resistant block 2 are not separated.

[0031] In an embodiment, as shown in the drawings, Figures 1-7 The mould further comprises a spring 5 acting on the sliding block 1 and the lower mould 9, which provides horizontal driving force for the sliding block 1 by means of the spring 5. Specifically, when the mould is closed, the inclined guide pillar 3 is inserted into the guide pillar hole 11 to drive the sliding block 1 to move to the inside of the mould, and in this process, the spring 5 is compressed under force. When the mould is opened, the sliding block 2 is driven by the inclined guide pillar 3 and the spring 5 to move to the outside, and when the sliding block 1 reaches the stop position, the inclined guide pillar 3 is separated from the guide pillar hole 11, and the current position of the sliding block 1 is ensured by the spring 5 to avoid movement so that the inclined guide pillar 3 cannot be inserted into the guide pillar hole 11 when the mould is closed.

[0032] In an embodiment, as shown in the drawings, Figures 1-7 The upper surface of the wear-resistant block 2 is provided with a through connecting hole 24, and the connecting hole passes through the fixing block 21; the wear-resistant block 2 is fixed to the lower mould 9 by means of screws. The connecting hole 24 is a counterbore, so that the screws are hidden in the connecting hole to avoid affecting the normal movement of the sliding block 1.

[0033] In an embodiment, as shown in the drawings, Figures 1-7 The lower mould 9 is concavely provided with a fixing groove 91 matched with the fixing block 21; during assembly, the fixing block 21 is inserted into the fixing groove 91 to support the fixing block 21 by means of the fixing groove 91, so as to improve the supportability of the wear-resistant block 2.

[0034] In an embodiment, as shown in the drawings, Figures 1-7 The fixing block 21 and the guide plate 22 are an integral structure, which further improves the strength of the wear-resistant block 2.

[0035] Compared with the original guide structure, the wear-resistant block of the utility model is compact in structure. Specifically, as shown in the drawings, Figure 8 The original structure needs to be provided with a wear-resistant plate 7 on the mould, and both sides form a guide groove matched with the sliding block through a pressing strip 8. The wear-resistant plate 7 needs to be fixed to the mould by means of two screws, and each pressing strip 8 needs to be positioned by means of two pins and fixed to the mould by means of two screws. It can be seen that the number of parts is large, and the installation steps are complicated. The wear-resistant block 2 of the utility model only needs two screws to realize the fixation of the wear-resistant block 2 and the mould.

[0036] The above is only a preferred embodiment of the utility model, and is not intended to limit the scope of the utility model; if the utility model is modified or replaced equivalently without departing from the spirit and scope of the utility model, it should be covered in the protection scope of the utility model claim.
