[0002] The slider is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action.

[0003] In the existing mold, the slider body can be used as a part of the mold molding cavity, and is positioned and matched with the slider by bolts arranged in the molding cavity. However, the bolts have defects when used, that is, when a larger bolt size is selected, it will be difficult to insert, and when a smaller bolt size is selected, a fitting gap will be generated. The fitting gap will cause the bolt to be wrapped by the injection molding material, which will increase the outer diameter of the bolt over time and make it impossible to insert the slider.

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] Referring to the accompanying drawings: This mold slider includes a slider body 1, and one side of the slider body 1 is provided with two molding cores 11 which are symmetrically distributed and placed in the molding cavity of the mold. The molding core 11 is provided with a positioning hole 12 on the slider body 1 for inserting a positioning bolt 2 installed in the molding cavity of the mold, and a sleeve 3 which can tightly match the positioning bolt 2 is provided in the positioning hole 12. The positioning hole 12 is provided with a first mounting hole 13 which is vertically arranged with the positioning hole 12 in the slider body 1, and an elastic unit 4 with a preset shape and compressible under extrusion is provided in the first mounting hole 13. The elastic unit 4 partially extends into the inner cavity of the sleeve 3 and has an abutment base surface 41. The outer peripheral surface of the lower section of the positioning bolt 2 has an abutment mating surface 21 which contacts the abutment base surface 41 and causes the elastic unit 4 to be squeezed. The abutment mating surface 21 forms a stop step 22 on the positioning bolt 2 which can quickly limit the final use position of the slider body 1 in the mold. The principle of the utility model is that when the slider body 1 is applied to the mold and used as a part of the molding cavity, the positioning bolt 2 is arranged in the molding cavity and plays a positioning role. It is inserted into the positioning hole 12 during injection molding. The elastic unit 4 abutting against the positioning bolt 2 has two functions. On the one hand, it is to quickly determine the final position of the positioning bolt 2 in the positioning hole 12, that is, it is achieved by the stop step 22 formed by the abutment mating surface 21 (the stop step 22 is achieved by utilizing the two sections of the positioning bolt 2 with different outer dimensions, and the outer dimension of the abutment mating surface 21 is smaller than the overall dimension). When the elastic unit 4 acts on the part with a smaller outer dimension (that is, the abutment mating surface 21), it is also placed at the stop step 22 at the same time, so as to prevent the positioning bolt 2 from continuing to move, and also enable the molding surface of the slider body 1 used to mold the molding core 11 to be kept at the same horizontal plane as the inner side surface of the molding cavity of the upper template and the lower template of the mold; on the other hand, the elastic unit 4 can be used as The filling component is used, that is, the size of the positioning bolt 2 can be slightly smaller than the inner diameter of the inner cavity of the sleeve 3. The smaller size means that the positioning bolt 2 will not be stuck when inserted into the inner diameter of the sleeve 3, making the insertion process smoother. However, this will cause a matching gap between the positioning bolt 2 and the sleeve 3, and the gap will cause the injection molding material to flow in. Therefore, the gap is filled by the abutment and matching of the elastic unit 4 and the positioning bolt 2. When the abutment base surface 41 of the elastic unit 4 abuts against the abutment matching surface 21 of the positioning bolt 2 (the abutment base surface 41 and the abutment matching surface 21 are both planes, and the two can fully abut against each other), the outer peripheral surface of the unformed abutment matching surface 21 of the positioning bolt 2 will abut against the inner peripheral surface of the inner cavity of the sleeve 3, and then the gap is filled by using the part of the elastic unit that enters the inner cavity of the sleeve 3 as the filling part, so as to achieve the effect of prohibiting inflow. At the same time, the elastic characteristics of the elastic unit 4 can adapt to positioning bolts 2 of various sizes, thereby improving adaptability. In this embodiment, the positioning bolt 2 is formed with abutment mating surface 21 so as to present a "D"-shaped configuration, and the configuration of the inner cavity of the insert sleeve 3 is consistent with the "D"-shaped configuration.

[0019] The positioning hole 12 is T-shaped, and the configuration of the insert sleeve 3 is consistent with that of the positioning hole 12, and a slot 31 is provided on the outer peripheral surface relative to the first mounting hole 13 for part of the elastic unit 4 to pass through and extend to the inner cavity of the insert sleeve 3. The T-shaped setting makes the positioning hole 12 and the insert sleeve 3 have narrow sections and wide sections. Such a configuration can quickly determine the final position of the insert sleeve 3 when inserted into the positioning hole 12, eliminating the adjustment time, and it only needs to be inserted to the bottom. The slot 31 enables the elastic unit 4 to extend into the inner cavity of the insert sleeve 3, thereby achieving abutment with the abutment mating surface 21 of the positioning bolt 2 entering the inner cavity of the insert sleeve 3.

[0020] The positioning hole 12 is provided with an installation groove 14 on the slider body 1, and a blocking block 14-a is provided in the installation groove 14 to prevent the sleeve 3 from falling out of the positioning hole 12 when subjected to force. Such a setting provides a blocking in the direction in which the sleeve 3 falls out of the positioning hole 12. The blocking can not only prevent the sleeve 3 from falling out under force, but also can utilize the blocking to ensure the stability of the sleeve 3 when the positioning bolt 2 is inserted into the sleeve 3.

[0021] The insert sleeve 3 is made of rubber material. Such a setting makes the insert sleeve 3 itself have a good flexibility effect, that is, the external thread of the positioning bolt 2 can be slightly embedded in the insert sleeve 3 under the action of the elastic unit 4, so that the gap caused by the thread can be filled. In this way, when separating from the positioning bolt 2 which is a metal part (i.e. demolding), the moving speed of the slider body 1 can be reduced, thereby improving the demolding quality.

[0022] The elastic unit 4 includes a combination body 42 with a preset shape, an extension body 43 extending from the combination body 42, and a support body 44. The abutment base surface 41 is formed on the combination body 42. The first mounting hole 13 has an assembly side surface 13-a opposite to the abutment base surface 41. The extension body 43 has a stop body 43-a that can contact the assembly side surface 13-a to fully display the combination body 42. A spring 5 with an elastic compression amount in the retraction direction of the elastic unit 4 is provided on the support body 44. The spring 5 provides support for the stop body 43-a or the extension body 43 so that the stop body 43-a maintains a state of contact with the assembly side surface 13-a. The combination body 42 is a block structure. The elastic unit 4 is moved by the combination body 42 and the extension body 43 in the direction extending to the insert sleeve 3. The performance of retraction under extrusion is realized, and when the stop body 43-a and the assembly side 13-a are in abutment, the combination 42 can be fully displayed, that is, the preset shape is displayed. The spring 5 is in an uncompressed state when the combination 42 is not squeezed by the abutment mating surface 21, and an elastic force is applied to the stop body 43-a or the extension body 43, thereby providing support so that the stop body 43-a remains in contact with the assembly side 13-a. When the combination 2121 is squeezed by the assembly mating surface 1b, the combination 42 and the extension body 43 move toward the support body 44, and the compression amount of the spring 5 increases to meet the movement variables of the combination 42 and the extension body 43, and can also provide sufficient abutment force so that the abutment base surface 41 and the abutment mating surface 41 always remain in abutment.

[0023] The first mounting hole 13 is provided with a second mounting hole 15 on the slider body 1 and is vertically arranged with respect to the first mounting hole 13. The support body 44 is arranged in the second mounting hole 15. The first mounting hole 13 has a side entrance on the slider body 1, so that the combination body 42, the extension body 43, and the spring 5 can enter from the side entrance. The second mounting hole 15 has an upper entrance on the slider body 1, so that the support body 44 can enter from the upper entrance and exist on the exit path of the combination body 42, the extension body 43, and the spring 5, and abut against the spring 5. This method makes it convenient to install the elastic unit 4 on the slider body 1.

[0024] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
