Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold and its dual-angle disordered core-pulling mechanism. Background Technology

[0002] Currently, when injection molds require multi-angle core pulling, most of the time it is achieved by one slider driving another slider. However, there is a time delay in the core pulling action of each slider, which determines the order of mold opening. Moreover, the mold structure design is relatively complex, resulting in high mold costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an injection mold and its dual-angle disordered core-pulling mechanism, which enables simultaneous dual-angle core pulling of the first and second sliders without requiring a specific mold opening sequence. It also offers advantages such as a simple, compact, and low-cost mold structure, while the mold structure is not easily restricted.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model provides a dual-angle disordered core-pulling mechanism for injection molds, including a fixed mold and a moving mold, and further including an inclined guide post, an inclined guide block fixed to the fixed mold, and a first slider and a second slider for core pulling; the fixed mold core of the fixed mold is equipped with the inclined guide post, and the first slider has a first guide groove that matches the inclined guide post, and the inclined guide post is movably inserted into the first guide groove; the moving mold core of the moving mold is equipped with a slidable second slider, and an inclined guide pin is equipped on the side of the first slider away from the fixed mold core, and the second slider has a second guide groove that matches the inclined guide pin, and the inclined guide pin is movably inserted into the second guide groove; when the mold is opened, the first slider slides obliquely on the inclined guide block, and the movement trajectory of the first slider is restricted by the extension direction of the inclined guide post, and simultaneously the movement trajectory of the second slider is restricted by the extension direction of the inclined guide pin, so that the first slider and the second slider together form a dual-angle disordered core pulling mechanism.

[0005] Furthermore, the first slider is placed at an angle, and the core-pulling direction of the first slider intersects with the core-pulling direction of the second slider.

[0006] Furthermore, a spring is provided between the moving mold core and the second slider.

[0007] Furthermore, the inclined guide block has an inclined surface on the side facing the first slider, and the first slider can slide against the inclined surface.

[0008] Furthermore, the inclined surface is provided with a first limiting member for limiting the movement distance of the first slider.

[0009] Furthermore, the moving mold core is provided with a second limiting member for limiting the movement distance of the second slider.

[0010] This utility model provides an injection mold, which includes at least the above-mentioned dual-angle disordered core-pulling mechanism.

[0011] The technical solution provided by this utility model has the following beneficial effects: When the mold is opened, the first slider slides obliquely on the oblique guide block, and the movement trajectory of the first slider is restricted by the extension direction of the oblique guide post to form a first angle core pulling. Simultaneously, the movement trajectory of the second slider is restricted by the extension direction of the oblique guide pin to form a second angle core pulling. That is, the first slider and the second slider together form a double angle core pulling. Moreover, there is no sequential mold opening order between the first slider and the second slider when pulling the core. It can also achieve the advantages of simple, compact mold structure and low cost. At the same time, the mold structure is not easily restricted. Attached Figure Description

[0012] Figure 1 The figure shown is a cross-sectional view of the dual-angle disordered core-pulling mechanism of the injection mold in Embodiment 1. Detailed Implementation

[0013] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] Example 1 Reference Figure 1 Example 1 provides a dual-angle disordered core-pulling mechanism for injection molds (hereinafter referred to as the core-pulling mechanism) for dual-angle core pulling during mold opening, and there is no sequential mold opening order.

[0016] The core-pulling mechanism of this embodiment includes a fixed mold, a moving mold, an inclined guide post 3, an inclined guide block 4 fixed to the fixed mold, and a first slider 5 and a second slider 6 for core pulling. The fixed mold core 1 of the fixed mold and the moving mold core 2 of the moving mold are arranged vertically, and the first slider 5 is placed at an angle. The core-pulling direction of the second slider 6 is horizontal. Therefore, the core-pulling direction of the first slider 5 intersects the core-pulling direction of the second slider 6.

[0017] More specifically, the fixed mold core 1 is equipped with an inclined guide post 3, and the first slider 5 has a first guide groove 51 that matches the inclined guide post 3. The inclined guide post 3 is movably inserted into the first guide groove 51. The moving mold core 2 is equipped with a slidable second slider 6. The bottom side of the first slider 5 away from the fixed mold core 1 is equipped with an inclined guide pin 52, and the second slider 6 has a second guide groove 61 that matches the inclined guide pin 52. The inclined guide pin 52 is movably inserted into the second guide groove 61.

[0018] An inclined surface 41 is provided on the side of the inclined guide block 4 facing the first slider 5. The first slider 5 can slide against the inclined surface 41 to ensure that the first slider 5 can slide upwards at an angle under the restriction of the inclined surface 41.

[0019] When the mold is opened, the movement trajectory of the first slider 5 is restricted by the extension direction of the inclined guide post 3, so that the first slider 5 slides upward at an angle and moves away from the cavity, thus realizing the first angle core pulling. At the same time, the first slider 5 synchronously drives the inclined guide pin 52 to perform corresponding movements, and the inclined guide pin 52 also synchronously drives the second slider 6 to perform corresponding movements and move away from the cavity, thus realizing the second angle core pulling. The first angle core pulling and the second angle core pulling are completed simultaneously.

[0020] In summary, by cooperating with the inclined guide post 3, the inclined guide block 4, the inclined guide pin 52, the first slider 5 and the second slider 6, dual-angle core pulling can be achieved simultaneously. That is, there is no sequential mold opening order between the first slider 5 and the second slider 6 when pulling the core. It can also achieve the advantages of simple, compact and low-cost mold structure, while the mold structure is not easily restricted.

[0021] In a further preferred embodiment, a spring 7 is provided between the moving mold core 2 and the second slider 6, and the elastic force of the spring 7 limits the movement of the second slider 6 away from the cavity under the push of the elastic force. Of course, in other embodiments, the spring 7 is an optional accessory.

[0022] More preferably, the inclined surface 41 of the inclined guide block 4 is provided with a first limiting member 42 for limiting the movement distance of the first slider 5.

[0023] More preferably, the moving mold core 2 is provided with a second limiting member 21 for limiting the movement distance of the second slider 6.

[0024] Example 2 Example 2 provides an injection mold that includes at least the dual-angle disordered core-pulling mechanism of Example 1.

[0025] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
