[0002] Injection molds are widely used in the manufacturing of a wide variety of products in the field of mold technology. However, for products with complex structures, especially those with large barb widths and depths, traditional mold release mechanisms often struggle to meet the requirements for efficient and precise demolding. This leads to product damage and demolding difficulties during actual production, which not only affects production efficiency but also increases production costs.

[0003] In traditional mold devices, the inclined ejector mechanism lacks a stable sliding mechanism and a limiting device, which causes the inclined ejector rod to easily shake or deflect during movement, thereby affecting the precision and molding quality of the mold; and in the inclined ejector mechanism of the slider in the existing mold device, only one product can be demoulded. When faced with diverse product production needs, since different products or molds may require inclined ejectors of different shapes and sizes, other molds need to be replaced, which is very troublesome.

[0004] Therefore, we have made improvements to this problem and proposed a slider inner inclined ejection mechanism in the mold device. Utility Model Content

[0035] In order to solve the technical problems in the background technology, the following slider inner inclined ejection mechanism in the mold device is provided:

[0036] Example 1:

[0037] Combine Figure 1 - Figure 7As shown, the utility model provides a slider inner inclined ejection mechanism in a mold device, comprising a mold body 1, a hydraulic telescopic rod 2 fixedly mounted on one side surface of the mold body 1, and a push block 3 fixedly connected to one end of the hydraulic telescopic rod 2, an outer slider 4 fixedly connected to one side surface of the push block 3, and the outer slider 4 and the push block 3 are both slidably connected in the mold body 1, an inclined ejector rod 5 is provided at one end of the outer slider 4, and a sliding mechanism 6 is provided between the inclined ejector rod 5 and the outer slider 4, and an inclined ejector head 7 is provided at one end of the inclined ejector rod 5. , and a connecting mechanism 8 is provided between the inclined ejector head 7 and the inclined ejector rod 5; the sliding mechanism 6 includes a slide groove 601, and the slide groove 601 is opened at the bottom of the outer slider 4, the inner slider 602 is slidably connected inside the slide groove 601, and a connecting groove 603 is opened on one side of the upper surface of the inner slider 602, a fixed rod 604 is fixedly installed inside the connecting groove 603, and the inclined ejector rod 5 is slidably connected to the fixed rod 604, and two inclined grooves 605 are opened inside the outer slider 4, and the inclined ejector rod 5 is slidably connected to the inclined groove 605.

[0038] In this embodiment: the hydraulic telescopic rod 2 can provide power for the push block 3 and push the outer slider 4 to slide inside the mold body 1; an inclined ejector rod 5 is cleverly provided at one end of the outer slider 4, and the stable movement of the inclined ejector rod 5 is achieved through the sliding mechanism 6, which is composed of a slide groove 601 and an inner slider 602 provided at the bottom of the outer slider 4. The inner slider 602 slides smoothly in the slide groove 601 and forms a sliding connection with the inclined ejector rod 5 through a fixed rod 604 fixedly installed in a connecting groove 603 on its upper surface. At the same time, the inclined ejector rod 5 also slides in two inclined grooves 605 provided inside the outer slider 4, ensuring its precise guidance during the demoulding process;

[0039] As a preferred embodiment, a limiting block 606 is fixedly installed on the lower surface of the inner sliding block 602 , a limiting groove 607 is provided on the bottom surface of the mold body 1 , and the limiting block 606 is slidably connected to the limiting groove 607 .

[0040] In this embodiment: the limit block 606 slides in the limit groove 607, which not only further enhances the stability of the inner slider 602 (and the inclined push rod 5 connected thereto) during the movement process, but also effectively prevents structural damage or inaccurate demolding caused by excessive movement or offset.

[0041] As a preferred embodiment, two mounting rods 608 are fixedly installed inside the slide groove 601, and the inner slider 602 is slidingly connected to the mounting rod 608. A groove 609 is provided on one side surface of the inner slider 602, and a return spring 610 is fixedly installed between the inner wall of the groove 609 and the inner wall of the slide groove 601. The return spring 610 is sleeved on the outside of the mounting rod 608.

[0042] In this embodiment: two mounting rods 608 are set inside the slide 601, and the inner slider 602 forms a sliding connection with the two mounting rods 608, which can provide a more stable guide for the movement of the inner slider 602 and enhance its sliding stability in the slide 601; in addition, a groove 609 is provided on one side surface of the inner slider 602, and a return spring 610 is fixedly installed between the inner wall of the groove 609 and the inner wall of the slide 601, and the return spring 610 is cleverly sleeved on the outside of the mounting rod 608, so that after completing a sliding action, the inner slider 602 can quickly and smoothly return to the initial position with the help of the elastic force of the return spring 610, and is fully prepared for the next demolding operation.

[0043] The working principle of embodiment 1: the hydraulic telescopic rod 2 drives the push block 3 and the outer slider 4 to retract. During the retraction process of the outer slider 4, the inner slider 602 will support the inner slider 602 through its own elastic force, so that the inner slider 602 slides relative to the outer slider 4, and through the limitation of the connecting groove 603 and the inclined groove 605, the inclined push rod 5 will first open to both sides. When the inner slider 602 slides to the other side of the slide groove 601, the outer slider 4 will drive the inner slider 602 to move, and retract the inclined push rod 5 and the inclined push head 7.

[0044] Example 2:

[0045] refer to Figure 1 、 Figure 6 and Figure 7 On the basis of the above embodiment, in order to be able to replace different inclined plugs 7 according to the requirements of different products, this embodiment provides the following design:

[0046] As a preferred embodiment, the connecting mechanism 8 includes a mounting block 801, and the mounting block 801 is fixedly mounted on one side surface of the inclined ejector head 7. A mounting groove 802 is provided on one end surface of the inclined ejector rod 5, and the mounting block 801 and the mounting groove 802 are connected by a snap-fit ​​connection.

[0047] In this embodiment: the connecting mechanism 8 is mainly composed of two parts: a mounting block 801 and a mounting groove 802, wherein the mounting block 801 is firmly fixed on one side surface of the inclined ejector head 7, and a mounting groove 802 is provided on one end surface of the inclined ejector rod 5; a snap-fit ​​connection method is adopted between the two parts, so that the inclined ejector head 7 can be easily and firmly connected to the inclined ejector rod 5, which simplifies the replacement process of the inclined ejector head 7 and enables the operator to quickly and accurately replace the appropriate inclined ejector head 7 according to the specific needs of different products, thereby greatly improving the production efficiency and flexibility of the mold device.

[0048] As a preferred embodiment, retaining grooves 803 are provided on the upper and lower surfaces of the mounting block 801, and a retaining block 804 is slidably connected inside the retaining groove 803, and a clamping block 805 is fixedly installed on one side surface of the retaining block 804, and clamping grooves 806 are provided on the upper and lower inner walls of the mounting groove 802, and the clamping block 805 is clamped and connected to the clamping groove 806.

[0049] In this embodiment: retaining grooves 803 are cleverly opened on the upper and lower surfaces of the mounting block 801, and a retaining block 804 is slidably connected inside the retaining groove 803, and a clamping block 805 is fixedly installed on one side surface of the retaining block 804, and clamping grooves 806 are correspondingly opened on the upper and lower inner walls of the mounting groove 802. When the mounting block 801 is inserted into the mounting groove 802, the retaining block 804 will slide in the retaining groove 803 until the clamping block 805 is fully engaged with the clamping groove 806, thereby realizing a firm connection between the inclined ejector head 7 and the inclined ejector rod 5.

[0050] As a preferred embodiment, a connecting spring 807 is fixedly installed between the stop block 804 and the inner wall of the stop groove 803, and one side surface of the clamping block 805 is inclined.

[0051] In this embodiment: a connecting spring 807 is specially provided between the stop block 804 and the inner wall of the stop groove 803. The introduction of the connecting spring 807 provides continuous elastic support for the stop block 804, so that the stop block 804 can maintain a stable position in the stop groove 803; and one side surface of the block 805 is designed to be inclined, which can squeeze the inclined surface of the block 805 through the inner wall of the installation groove 802. When the block 805 is aligned with the slot 806, the connecting spring 807 will push out the block 804 and the block 805, so that the block 805 and the slot 806 are engaged, and the operation is more convenient.

[0052] The working principle of the second embodiment: Press the blocks 805 on both sides so that the blocks 805 are not engaged with the slots 806, which makes it easier to remove different bevel heads 7. When the bevel heads 7 need to be replaced to meet the demoulding requirements of different products, the operator first aligns the mounting block 801 on the new bevel head 7 with the mounting slot 802 at one end of the bevel rod 5 and inserts it. As the mounting block 801 gradually goes deeper, the block 804 on it will slide in the block slot 803, and the connecting spring 807 will be compressed at the same time. Since one side surface of the block 805 is inclined, the inner wall of the mounting groove 802 will squeeze the inclined surface of the block 805, causing the block 804 to slide further into the blocking groove 803. When the mounting block 801 is fully inserted into the mounting groove 802 and the block 805 is aligned with the blocking groove 806, the connecting spring 807 quickly recovers its deformation, ejecting the block 804 and the block 805, so that the block 805 is tightly engaged with the blocking groove 806, thereby achieving a firm connection between the inclined ejector head 7 and the inclined ejector rod 5.

[0053] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0054] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
