DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0022] like Figures 1 to 5 As shown, the utility model provides a mold with a slide retracted after mold opening, comprising a lower mold 1, wherein the lower mold 1 is provided with at least one mold core 2, the mold core 2 is a hollow structure, and at least one side of the mold core 2 is provided with a slide hole 3; a slide module 4 is provided in the mold core 2, the slide module 4 comprises a driving member 5 and at least one snap-on slide 6, the snap-on slide 6 is movably arranged in the slide hole 3, and the driving member 5 is used to drive the snap-on slide 6 to extend out of the slide hole 3 or retract into the slide hole 3.

[0023] In actual use, the utility model also has conventional structures such as an upper mold and an ejection mechanism, but since such structures do not belong to the internal scope of the utility model, they will not be described or displayed in detail.

[0024] When the utility model is working, the product 7 is covered outside the mold core 2 after injection molding. At this time, the buckle slider 6 is in an extended state so that the product 7 forms a corresponding buckle groove 71; before the product 7 needs to be demolded after cooling, the driving member 5 drives the buckle slider 6 to retract into the slider hole 3, so that the product 7 will not contact the buckle slider 6 during the ejection process, so as to avoid damage to the inner side wall of the product 7 and ensure the quality of the product 7.

[0025] In this embodiment, the driving member 5 is used to connect an external cylinder for driving the driving member 5 to move up and down. A transmission part 51 is provided on the top of the driving member 5. The width and / or thickness of the transmission part 51 gradually decreases from the bottom to the top. At least one transmission groove 52 is provided on the side of the transmission part 51. The transmission groove 52 is arranged along the side of the transmission part 51. The sliding buckle is provided with a mounting part 61, and the mounting part 61 is slidably arranged in the transmission groove 52.

[0026] The slide buckle expands and contracts in the slide hole 3 as the transmission part 51 rises and falls.

[0027] The driving member 5 acts on a mechanical principle, and the transmission part of the buckle slide 6 is installed on the rear mold fixing plate of the lower mold 1; when the mold is opened, the rear mold plate and the rear mold fixing plate are separated.

[0028] That is, the driving member 5 is installed in the cylinder located in the lower mold 1, and the cylinder controls the lifting and lowering of the driving member 5; since the side wall of the driving member 5 is a narrow upper and wide lower structure, as the driving member 5 is lifted and lowered, the buckle slide 6 must be extended and retracted along the slide hole 3, thereby achieving the effect of controlling the buckle slide 6 to extend before injection molding, and controlling the buckle slide 6 to retract into the slide hole 3 before the product 7 is demolded.

[0029] Specifically, the mounting portion 61 increases in width from one end close to the slide buckle to the other end; the transmission slot 52 gradually decreases in width from one end close to the transmission portion 51 to the other end; the width of the transmission slot 52 away from the transmission portion 51 is smaller than the width of the slide buckle.

[0030] That is, the cross-sectional shapes of the mounting portion 61 and the transmission groove 52 are both trapezoidal, to ensure that the mounting portion 61 is always located in the transmission groove 52, to prevent the mounting portion 61 from being separated from the transmission groove 52 or the buckle position 6 from entering the transmission groove 52, thereby ensuring the transmission effect.

[0031] Specifically, the slide buckle is provided with a mounting portion 61 on one side thereof having a resisting inclined surface 62, the shape of which is adapted to the shape of the side of the transmission portion 51, and the resisting inclined surface 62 resists against the transmission portion 51, thereby ensuring that the slide buckle will not flip relative to the transmission portion 51, so that the posture of the slide buckle remains unchanged.

[0032] In this embodiment, the driving member 5 and the transmission part 51 are integrally formed.

[0033] In this embodiment, the driving member 5 is provided with a clearance hole 53 , which is arranged along the height direction of the driving member 5 and penetrates the driving member 5 , and the clearance hole 53 is used to make way for the ejector pin.

[0034] By setting the clearance hole 53 , the ejector pin can pass through the transmission part 51 and the mold core 2 to directly lift up the product 7 , so as to ensure that the lifting action and the action of the transmission part 51 do not interfere with each other.

[0035] In this embodiment, a mounting platform 54 is provided at the bottom of the driving member 5 , and the width of the mounting platform 54 is greater than the width of the driving member 5 , so as to facilitate positioning and installation.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
