[0027] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0028] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0030] An embodiment of the utility model provides a core pulling structure applied to a vacuum cleaner mold, comprising: a panel assembly 1, an upper mold assembly 3 and a lower mold assembly 2 arranged in sequence from left to right, the upper mold assembly 3 comprising an upper model core 301, an upper model core hole 302 being opened in the upper model core 301, the panel assembly 1 is provided with a first slider 101 penetrating the upper model core hole 302, the upper model core 301 is provided with a first core 303 and a second slider 304 slidingly connected with the first slider 101, a first protruding structure 305 is provided on one side of the second slider 304, the first slider 101, the second slider 304 and the first core 303 together constitute a first molding surface 306, when the panel assembly 1 drives the first slider 101 to move upward, the second slider 304 moves in the opposite direction to the extension direction of the first protruding structure 305.

[0031] The first slider 101 of the utility model is fixed under the panel assembly 1, and the panel assembly 1 is ejected so that the first slider 101 moves with the panel assembly 1. By providing an upper model core hole 302 on the upper model core 301, the first slider 101 moves up and down along the upper model core hole 302 during demoulding or resetting. The first slider 101 and the second slider 304 provided with a first protruding structure 305 are matched and connected. The first protruding structure 305 can be square, semicircular or other shapes, which are used to form a structure such as a mounting hole for injection molded parts. The matching connection structure of the two sliders can be a groove connection structure, an inclined guide column structure, an inclined top structure connection or other structures. Through the matching connection, when the first slider 101 moves, it will drive the second slider 304 to move, which facilitates the first protruding structure 305 to be effectively and non-destructively demoulded and extracted. At the same time, the first slider 101, the second slider 304 and the first core 303 jointly constitute the first molding surface 306 to form the shape of the injection molded part, which facilitates product molding while taking into account the core pulling function.

[0032] In some embodiments, a guide groove 307 is provided on one side of the second sliding block 304, and the first sliding block 101 is provided with a protrusion 308 that can slide in the guide groove 307 and gradually tilt inward from top to bottom.

[0033] The protrusion 308 can be in other shapes such as T-shaped, dovetail-shaped, I-shaped, etc. When demolding, the ejection stroke of the panel assembly 1 does not exceed the length of the guide groove 307. The shape of the guide groove 307 matches the protrusion 308, which facilitates the relative sliding of the first slider 101 on the guide groove 307 to generate displacement for core pulling and demolding.

[0034] In some embodiments, the upper mold core 301 is provided with a slider seat 309 , the slider seat 309 is provided with a first slide groove 310 , and the second slider 304 is slidably connected to the first slide groove 310 .

[0035] The slider seat 309 is fixed under the upper mold core 301, and the second slider 304 is arranged on the first slide groove 310 of the slider seat 309, so that the slider seat 309 and the second slider 304 move together with the mold opening, and the second slider 304 can move on the first slide groove 310.

[0036] Furthermore, a second protruding structure 312 for forming a second molding surface 314 is provided below the slider seat 309 .

[0037] The second protruding structure 312 below the slider seat 309 enables the product to form an arc edge or other structure.

[0038] In some embodiments, the inner wall of the upper mold core hole 302 is provided with a second slide groove 311 , and the width of the first sliding block 101 gradually increases from bottom to top.

[0039] A second slide groove 311 is set on one side of the upper model core hole 302, and the other three sides are vertical surfaces. The upper model core hole 302 corresponds to the shape of the first slider 101, so that when the first slider 101 is demolded or reset and moves up and down, the protrusion 308 of the first slider 101 slides in the second slide groove 311 in the upper model core hole 302, and at the same time, the width of the first slider 101 gradually increases from bottom to top, so that the first slider 101 achieves a limiting effect.

[0040] In some embodiments, the first core 303 is a concave structure capable of accommodating the first slider 101 and the second slider 304 .

[0041] The first slider 101 is conveniently combined with the second slider 304 to be embedded in the concave first core 303 to form the first molding surface 306 together.

[0042] Furthermore, a third protruding structure 313 is provided on the upper side of the first core 303 .

[0043] The first core 303 is fixed below the upper model core 301. During the demolding process, the molding structure formed by the first core 303, the first slider 101 and the second slider 304 is directly demolded along with the upper model core 301 when the third protruding structure 313 is opened, and the structure arranged on the upper edge can be demolded upward without interference.

[0044] In some embodiments, the first protruding structure 305 is disposed on the other side opposite to the guide groove 307 .

[0045] The first protruding structure 305 is disposed on the back side or the other side opposite to the guide groove 307 , so that the guide groove 307 can drive the first protruding structure 305 to be core-pulled and demoulded.

[0046] In some embodiments, the first molding surface 306 is an arc-shaped structure.

[0047] The bottom of the first slider 101, the second slider 304 and the first core 303 are designed as an arc structure according to the product, and can also be designed into other structures according to other product requirements, so as to improve the utilization rate of the core pulling structure and reduce the production design cost.

[0048] In some embodiments, a limiting structure 315 is disposed on one side of the first sliding block 101 .

[0049] The limiting structure 315 of the first slider 101 can be a protrusion 308, a groove, a ball positioning structure, etc., which is used to limit the distance between the first slider 101 and the first core 303 to prevent the first slider 101 from pushing out of the first molding surface 306 and causing molding problems, thereby improving product accuracy and quality.

[0050] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
