[0036] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0037] It should be clear that the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0038] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present application. The singular forms "a," "the," and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0039] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0040] In this application, unless otherwise specified, "plurality" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exists simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0041] Combine Figures 1 to 6 As shown, the utility model provides a core-pulling structure of a car seat mold, which includes: a movable template 10, which has a product 60; a bottom plate 20, which is arranged below the movable template 10; a shovel base 30, the lower end of which is connected and fixed to the bottom plate 20; the upper end of the shovel base 30 is provided with an inclined surface 310, the inclined surface 310 is inclined from top to bottom and from back to front, and a guide groove 311 is provided on the inclined surface 310; a slider unit, which includes a guide bar 410 and a slider 420 arranged on the guide bar 410, the guide bar 410 is slidably arranged in the guide groove 311, and a plurality of rib position grooves 421 are provided on the front side of the slider 420, and the plurality of rib position grooves 421 correspond to the rib positions of the product;

[0042] When the mold is closed, the upper end of the shovel base 30 and the slider unit are located in the movable mold plate 10, and the slider unit is in contact with the product; when the mold is opened, the slider unit moves obliquely upward along the length direction of the guide groove 311 under the opening action of the movable mold plate 10.

[0043] Compared with the prior art, after the injection molding is completed, the present application pulls the movable template 10 upward by the buckle machine 50. Since the shovel base 30 is fixed on the bottom plate 20, the slider 420 will move obliquely upward along the length direction of the guide groove 311 driven by the undercut part of the product until the movable template 10 is pulled to a preset stroke (for example, height H). Since the shovel base 30 originally located behind the slider 420 moves relatively downward, the corresponding space is freed up for the slider 420 to retreat and separate from the product, thereby realizing demolding, and the demolding process is simple.

[0044] In this embodiment, a mounting groove 422 is provided on the front side of the slider 420, and a mounting hole is provided in the mounting groove 422. The slider unit also includes a mounting block 423, which is disposed in the mounting groove 422 and is detachably connected to the guide bar 410 via a locking bolt. In this embodiment, the mounting block 423 is connected to the guide bar 410 to achieve a fixed connection between the slider 420 and the guide bar 410. Furthermore, the locking bolt is passed through the mounting hole and then tightened to the mounting block 423. Moreover, in this embodiment, the mounting block 423 is selected as the component connected to the locking bolt. When problems such as slipping occur, only the mounting block 423 needs to be replaced, without replacing the slider 420.

[0045] Furthermore, a secondary rib position groove is provided on the mounting block 423, and the secondary rib position groove corresponds to the rib position setting of the product. The secondary rib position groove on the mounting block 423 is cooperated with the rib position groove 421 on the slider 420 to fill the part of the rib position groove 421 on the slider 420 that is missing due to the opening of the mounting groove 422.

[0046] In one embodiment, a limiting groove is provided at the upper end of the shovel base 30, and the limiting groove is communicated with the guide groove 311; the slider unit also includes a limiting block 430, and the limiting block 430 is detachably connected to the rear side of the slider 420; when the mold is closed, the limiting block 430 is located in the limiting groove, and the lower side of the limiting block 430 is against the limiting groove, and the limiting block 430 and the limiting groove are used to determine the relative position of the slider 420 and the upper end of the shovel base 30, so that when the mold is closed, the slider 420, the limiting block 430 and the upper end of the shovel base 30 can be combined to form a molding surface.

[0047] Furthermore, the limiting block 430 is detachably connected to the slider 420 via a locking bolt, so that the slider 420 of other shapes can be replaced according to the shape of the product.

[0048] Furthermore, auxiliary molding blocks 440 are respectively provided on the left and right sides of the slider 420; when the mold is closed, the auxiliary molding blocks 440, the slider 420, the limit block 430 and the upper end of the shovel base 30 are combined into a molding surface, and the molding surface is set corresponding to the shape of the product so as to cooperate with the fixed mold plate and the movable mold plate 10 to better perform injection molding on the product.

[0049] Furthermore, positioning bars 441 are respectively provided on the left and right sides of the slider 420; a positioning groove is provided on the side of the auxiliary molding block 440 facing the slider 420, and the positioning groove is arranged corresponding to the positioning bar 441; when the mold is closed, the positioning bar 441 is inserted into the positioning groove for assembly and disassembly.

[0050] Furthermore, the length direction of the positioning bar 441 is arranged from front to back.

[0051] In this embodiment, the left and right sides of the shovel base 30 are respectively provided with limit grooves 320, and the limit grooves 320 are provided with limit members 330; when the mold is closed, the limit members 330 are abutted against the bottom of the movable template 10, and the limit members and the bottom of the movable template are used to limit the position of the shovel base.

[0052] In the description of the present invention, it should be understood that the terms "vertical", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection content of the present invention.
