[0033] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0034] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-4 As shown, this application relates to a demolding mechanism and a mold. Figure 1-3 As shown, this demolding mechanism includes a rear mold core 10; the rear mold core 10 refers to the supporting molding cavity, and together with the front mold core (or front mold core), it forms the molding cavity of the mold, responsible for receiving and fixing the injected molten plastic. This forms the shape and structure of the product, ensuring the proper flow and cooling of the molten plastic.

[0037] Demolding of molded products: The rear mold core 10 is usually equipped with a demolding mechanism, such as a slanted ejector (core-pulling) function, which allows for smooth demolding when the mold is opened, preventing the molded plastic product from sticking inside the mold. Through the slanted ejector, slider and other mechanisms of the rear mold core 10, demolding of complex shaped parts can be effectively achieved.

[0038] Injection pressure distribution: The rear mold core 10 can evenly distribute the injection pressure, helping the plastic melt flow to each cavity of the mold, ensuring the quality and molding accuracy of the plastic parts.

[0039] The rear mold insert 20 is disposed within the rear mold core 10 along the first direction; by embedding the rear mold insert 20 into the rear mold core 10, a good fitting effect can be achieved; preferably, the rear mold insert 20 has a molding cavity; it can cooperate with other components to achieve a good molding effect.

[0040] The slider assembly 30 is at least partially connected to the rear mold core 10 along the second direction, and its movable end is close to or far from the rear mold insert 20; it can achieve a good sliding effect, thereby ensuring good sliding demolding.

[0041] It should be noted that the first direction is the vertical direction, the second direction is the horizontal direction, and the first direction is perpendicular to the second direction; the vertical direction can also be the Y-axis direction in the two coordinate systems, and the horizontal direction can be the X-axis direction in the two coordinate systems.

[0042] The drive assembly 40 is connected along the second direction to the slider assembly 30 on the side away from the rear mold insert 20; it can ensure a good driving effect, thereby enabling other components to operate stably.

[0043] The driving component 40 provides driving force to move the slider component 30 to a preset position so that the movable end of the slider component 30 is separated from the product formed on the rear mold insert 20.

[0044] Specifically, the drive assembly 40 provides power and transmits the driving force to the slider assembly 30 through a mechanical transmission system;

[0045] Slider assembly 30 movement: After the drive assembly 40 starts working, the slider assembly 30 begins to move according to a preset path or position. Preferably, the slider assembly adopts a two-step demolding method; that is, the first step is pre-separation, in which the third slider insert 304 is pulled out first. This prevents the plastic product from sticking to the third slider insert 304 during demolding. At the same time, the purpose of the third slider insert 304 is also to release air and facilitate processing. The two-step retraction method improves the risks existing in the mold opening process.

[0046] The drive component 402 continues to drive the slider to move. At this time, the first slider insert 302 drives the second slider insert 303 to move backward, so that the workpiece is separated from the plastic product and demolding is completed.

[0047] Product separation at the moving end: The moving end of the slider assembly 30 contacts the product formed on the rear mold insert 20, and separates the product from the mold as the slider moves.

[0048] Automatic demolding: After the slider assembly 30 has traveled a certain distance or position, it completely separates the molded product from the rear mold insert 20, ensuring that the product can be smoothly removed when the mold is opened, avoiding sticking, jamming or damage.

[0049] The mold structure of this application can efficiently form products and ensure smooth demolding, reduce manual intervention, improve the level of production automation, and at the same time guarantee the integrity and quality of the formed products.

[0050] As can be seen from the above description, this application achieves the following technical effects:

[0051] In this embodiment, a simplified structure is adopted. The driving component 40 provides driving force to move the slider component 30 to a preset position, so that the movable end of the slider component 30 separates from the product formed on the rear mold insert 20. This achieves the purpose of automatic demolding of the mold and the product, thereby realizing the technical effects of easy demolding, improved production efficiency and protection of the outer surface of the product. It also solves the technical problems that the temperature of the product is still high in the mold after it has just been shaped, and manual demolding is prone to burns. Traditional demolding methods are inefficient during the demolding process and can easily cause scratches on the surface of the product, thus affecting the product qualification rate.

[0052] Furthermore, the rear mold core 10 is provided with a receiving cavity 101. It can be understood that by providing the receiving cavity 101, a good receiving effect can be achieved, thereby achieving a good assembly effect with other components.

[0053] like Figure 2and 4 As shown, the slider assembly 30 includes: a slider base 301, a first slider insert 302 disposed on the side of the slider base 301 along the second direction and close to the rear mold insert 20, a second slider insert 303 disposed on the side of the first slider insert 302 away from the slider base 301, and a third slider insert 304 that protrudes at least partially along the second direction from the second slider insert 303. It is understood that this design achieves a good sliding fit, thereby enabling the third slider insert 304 to move in a directional manner.

[0054] Furthermore, a fourth slider insert 305 is provided on the periphery of the third slider insert 304 and on the side close to the rear mold insert 20. It is understood that this allows for a good fit with the third slider insert 304, thereby ensuring structural stability.

[0055] Furthermore, the diameter of the third slider insert 304 decreases along the second direction from the first slider insert 302 towards the rear mold insert 20. It is understood that by adopting a decreasing diameter, the effect of easy demolding can be achieved.

[0056] Furthermore, a limiting member 306 is provided between the slider seat 301 and the second slider insert 303. The limiting member 306 passes through the first slider insert 302, and the slider seat 301 and the first slider insert 302 cooperate with a pre-set limiting distance 307 to limit the movement of the limiting member 306 within the limiting distance 307. It is understood that this achieves a good limiting effect, thereby ensuring a precise demolding effect; simultaneously, the pre-set limiting distance 307 allows the limiting member 306 to move within this distance. Preferably, the limiting member 306 is a screw; this facilitates easy implementation and operation.

[0057] Furthermore, a wear-resistant plate 308 is provided at the bottom of the slider seat 301. It is understood that this achieves good wear resistance, thereby increasing service life.

[0058] Furthermore, the driving assembly 40 includes: a base 401 connected to the wear-resistant plate 308 on the side away from the slider seat 301; a driving component 402 with its output end facing the slider seat 301 is provided on the base 401 along the second direction; and a connecting member 403 is provided at the output end of the driving component 402, which is connected to the slider seat 301. It is understood that this achieves a good driving effect, thereby realizing a precise automatic demolding effect. The driving component 402 can be a hydraulic cylinder, the base 401 can be a hydraulic cylinder seat, and the connecting member 403 can be a hydraulic cylinder connector; thus achieving a good transmission effect.

[0059] Furthermore, a plurality of connecting blocks 50 are provided between the base 401 and the rear mold core 10, and an assembly cavity 501 for assembling the slider seat 301 is reserved between the plurality of connecting blocks 50. It can be understood that this can achieve a good fixed connection effect between components, thereby improving the structural strength; at the same time, it can also facilitate assembly.

[0060] This application also relates to a mold, including the demolding mechanism described above.

[0061] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
