Technical Field
[0001] This utility model relates to the field of molds, and more specifically, to a collision-resistant slider mold structure with oblique sliding mechanism. Background Technology
[0002] A mold is a tool used to create molded products. Different shapes of molds are used to create products of different shapes. During the injection molding process, due to the structural characteristics of the product, different side sliders need to be designed to assist the mold in closing and opening. In the injection molding process, the mold is set horizontally. The upper slider is called the top side slider, and the lower slider is called the bottom side slider. Under the action of gravity, the top side slider is prone to sliding down, which can lead to the problem of mold collision when closing the mold. Traditional molds use springs or wave columns to position the top side slider after opening the mold due to gravity. However, springs have a limited service life. When the spring fails or its condition is unstable, the slider is very likely to fall off and cause mold damage, which poses a significant safety hazard and economic loss risk. Utility Model Content

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a slanted sliding anti-collision slider mold structure, comprising a panel, a pad, a fixed template, a moving template, and a base plate. A locking block is provided at the bottom of the pad. The fixed template has a T-shaped hole, and two inwardly retracting sliders are provided in the T-shaped hole. The locking block slides in cooperation with the inwardly retracting sliders. An inclined guide post is provided at the bottom of the fixed template. A core is provided on the moving template. Outer sliders are slidably provided on both sides of the core. The outer sliders have inclined guide holes. A latch is provided on the side near the inclined guide holes. The latch includes a crank, a positioning rod, a spring, and a positioning groove. The spring is sleeved on the positioning rod. One end of the crank extends into the inclined guide hole, and the other end is hinged to the upper end of the positioning rod. The positioning groove is opened on the moving template.
[0005] Furthermore, inclined dovetail guide blocks are provided on both sides of the locking block, a dovetail groove is opened on the end face of the inward sliding block near the dovetail guide block, and a forming groove is opened on the lower side of the inward sliding block.
[0006] Furthermore, spring clips are installed on both sides of the horizontal portion of the T-shaped hole, and two limiting grooves are respectively opened on both sides of the inward sliding block.
[0007] Furthermore, the upper surface of the outer slider has a mounting groove that connects to the inclined guide hole, the bottom of the mounting groove has a through guide hole, a base is installed in the mounting groove, the base has a square groove, the crank is hinged to the square groove, the positioning rod is slidably placed in the guide hole, the positioning rod is aligned with the positioning groove, the positioning rod has an annular step, one end of the spring abuts against the annular step, and the other end abuts against the bottom.
[0008] Furthermore, a roller is installed at the end of the crank facing the oblique guide hole.
[0009] Furthermore, two wedge-shaped blocks are further provided at the bottom of the fixed template.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model includes a panel, a pad, a fixed template, a movable template, and a base plate. A locking block is provided at the bottom of the pad. The fixed template has a T-shaped hole with two inward sliding blocks. The locking block and the inward sliding blocks are slidably engaged.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0016] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0017] Example Reference Figure 1-7 As shown, this utility model discloses a cover forming mold, including a panel 10, a pad 20, a fixed template 30, a movable template 40, and a base plate 50. A locking block 201 is provided at the bottom of the pad 20. The fixed template 30 has a T-shaped hole, and two retractable sliders 301 are provided in the T-shaped hole. The locking block 201 and the retractable sliders 301 are slidably engaged. Specifically, inclined dovetail guide blocks are provided on both sides of the locking block 201. The end face of the retractable slider 301 near the dovetail guide block has a dovetail groove. A forming groove is provided on the lower side of the retractable slider 301. When the mold is opened, the locking block 201 opens and drives the two retractable sliders 301 to move closer to each other, so that the forming groove is disengaged from the inner wall of the product. Since the forming groove is located on the lower side of the retractable slider 301, the two retractable sliders 301 only need to move a small distance to achieve the demolding of the forming groove. The locking block 201 opens a certain stroke and maintains a non-disengaging engagement with the retractable slider 301, thereby preventing the mold from being damaged due to inaccurate positioning when the sliders are closed. Furthermore, spring clips are installed on both sides of the horizontal part of the T-shaped hole, and two limiting grooves are opened on both sides of the inner sliding block 301. The spring clips correspond to the two limiting grooves, which correspond to the two states of the inner sliding block 301 when the mold is open and closed, and play a positioning role for the inner sliding block 301.
[0018] Reference Figure 4-7As shown, a slanted guide post 302 is provided at the bottom of the fixed template 30, and a core 404 is provided on the moving template 40. Outer sliders 401 are slidably provided on both sides of the core 404. The outer sliders 401 have slanted guide holes. A latch 402 is provided on the side near the slanted guide holes. The latch 402 includes a crank 4022, a positioning rod 4021, a spring 4023, and a positioning groove 403. The spring 4023 is sleeved on the positioning rod 4021. One end of the crank 4022 extends into the slanted guide hole, and the other end is hinged to the upper end of the positioning rod 4021. The positioning groove 403 is opened on the moving template 40. Specifically, the upper surface of the outer slider 401 has a mounting groove that connects to the inclined guide hole. A through guide hole is located at the bottom of the mounting groove. A base 4025 is installed inside the mounting groove. The base 4025 has a square slot. The crank 4022 is hinged to the square slot. The positioning rod 4021 is slidably placed in the guide hole, aligned with the positioning groove 403. The positioning rod 4021 has an annular step. One end of the spring 4023 abuts against the annular step, and the other end abuts against the bottom. During mold closing, the inclined guide post 302 inserts into the inclined guide hole, pushing the crank 4022 into the portion of the inclined guide hole. 022 connects to one end of the positioning rod 4021, which drives the positioning rod 4021 to be placed inside the outer slider 401 and compresses the spring 4023. When the mold is opened, the fixed platen 30 drives the inclined guide post 302 to leave the inclined guide hole and drive the outer slider 401 to move. When the inclined guide post 302 completely leaves the inclined guide hole, under the action of the spring 4023, the positioning post extends out of the outer slider 401 and inserts into the positioning groove 403 of the moving platen 40, which plays a positioning role for the moving platen 40 and prevents the fixed platen 30 from slipping when the horizontal mold is injected. This ensures that the inclined guide post 302 can be aligned with the inclined guide hole when the mold is closed, preventing the mold from colliding.
[0019] Furthermore, a roller 4024 is installed at the end of the crank 4022 facing the inclined guide hole. When the inclined guide post 302 moves along the inclined guide hole, it pushes the roller 4024, thereby driving the positioning rod 4021 to compress the spring 4023. The roller 4024 reduces the friction between the inclined guide post 302 and the crank 4022.
[0020] In addition, two wedge blocks are further provided at the bottom of the fixed template 30. When the mold is closed, the two wedge blocks abut against the two outer sliders 401, which play a role in pressing and fixing the two outer sliders 401.
[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
