Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a double-sided locking structure of a slider of a die-casting mold. Background Art

[0002] Die-casting molds are a type of material forming mold commonly used for industrial parts. There are many types of die-casting molds with different structures. Various sliders have become common structures in die-casting molds. Due to the limitations of the mold structure, the sliders often cannot be locked in the locking structure of the sliders that were previously set obliquely. When the locking height exceeds the limited range, elasticity will occur. When the slider is pressed and discharged outward, the lock will bounce outward, causing flash on the product and causing the product size to be out of tolerance. Therefore, a reliable locking structure is needed to prevent the slider from retreating. Utility Model Content

[0003] The utility model provides a double-sided locking structure for a slider of a die-casting mold, which has a simple structure and can solve the problem that a slider obliquely arranged in the die-casting mold cannot be locked by a traditional locking structure.

When the die-casting mold is completed, the opposite side surfaces of the locking block are respectively abutted against the top of the slider seat and the inner side wall of the movable mold core to prevent the slider and the slider seat from retreating. The slider can be effectively prevented from retreating by simultaneously supporting the slider seat and the movable mold frame on both sides of the locking block.

[0005] Preferably, both sides of the locking block are inclined surfaces, the top of the slider seat is provided with a matching first extrusion slope, and the inner side wall of the movable mold core is provided with a second extrusion slope matching the locking block, the first extrusion slope and the second extrusion slope can generate locking forces in the X direction and the Y direction, and the locking effect is good.

[0007] Preferably, mounting grooves are provided on both opposite side surfaces of the locking block, and the locking friction block is installed and limited in the mounting grooves, so that the locking friction block can be fully limited.

[0008] Preferably, two locking friction blocks are installed side by side in the installation groove to meet the large-area extrusion contact and reduce the manufacturing cost of the locking friction blocks.

[0009] Preferably, the fixed mold frame is provided with an inclined guide column inserted into the slider seat to realize the movement of the slider seat and the slider when the mold is opened and closed.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-5As shown, the utility model is to solve the problem that the slider obliquely arranged in the die-casting mold cannot be locked by the traditional locking structure. The following technical solution is provided: a double-sided locking structure of the slider of the die-casting mold, including a fixed mold frame 1 and a movable mold frame 2 arranged side by side, a fixed mold core 8 and a movable mold core 9 are arranged between the fixed mold frame 1 and the movable mold frame 2, sliders 6 are obliquely arranged on both sides between the fixed mold core 8 and the movable mold core 9, one end of the slider 6 is connected to the slider seat 7, and a locking block 3 extending toward the movable mold frame 2 is installed on the inner side of the fixed mold frame 1. When the die-casting mold is completed, the opposite sides of the locking block 3 are respectively against the top of the slider seat 7 and the inner side wall of the movable mold core 9 to prevent the slider 6 and the slider seat 7 from retreating. The two sides of the locking block 3 simultaneously support the slider seat 7 and the movable mold frame 2 to effectively prevent the slider 6 from retreating.

[0021] Specifically, the fixed mold frame 1 is equipped with an inclined guide column 10 inserted into the slider seat 7, which realizes the movement of the slider seat 7 and the slider 6 when the mold is opened and closed. When the mold is closed, the inclined guide column 10 will push the slider seat 7 and the slider 6 to the position between the fixed mold core 8 and the movable mold core 9, which is used for molding the product inside the mold cavity. When the mold is closed, the locking block 3 will not move, but the movable mold frame 2 will drive the entire movable mold core 9, the slider seat 7 and the slider 6 to move together, so that the locking block 3 is against the rear side of the slider seat 7, and the locking block 3 is also against the inner side wall of the movable mold frame 2, so that the locking block 3 occupies the space between the slider seat 7 and the inner side wall of the movable mold frame 2, realizing the force contact between the slider seat 7 and the movable mold frame 2, which can effectively prevent the slider seat 7 from retreating.

[0022] In order to improve the locking effect, Figure 1-4 As shown, the two opposite side surfaces of the locking block 3 are both inclined surfaces, the top of the slider seat 7 is provided with a matching first extrusion slope 71, and the inner side wall of the movable mold core 9 is provided with a second extrusion slope 4 matching the locking block 3. The first extrusion slope 71 and the second extrusion slope 4 can generate locking forces in the X direction and the Y direction, and the locking effect is good.

[0023] In this embodiment, locking friction blocks 5 are provided on both opposite sides of the locking block 3. The locking friction blocks 5 have a wear-resistant effect. The locking friction blocks 5 are not only wear-resistant, but also have a lubricating effect. They are not easy to be worn, and even if they are worn, they are very convenient to replace.

[0024] In order to limit the locking friction block 5 and facilitate maintenance, the locking block 3 is provided with mounting grooves 31 on both sides of the opposite sides. The locking friction block 5 is installed and limited in the mounting grooves 31, which can fully limit the locking friction block 5. Figure 3 and 5As shown, two locking friction blocks 5 are installed side by side in the installation groove 31 to meet the large-area extrusion contact and reduce the manufacturing cost of the locking friction blocks 5.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
