Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a retractable inner sliding structure. Background Technology

[0002] In various molding dies such as injection molds and die-casting molds, whether it is for thermoplastic plastics, thermosetting plastics, or various metal materials, demolding can be achieved by using an internal sliding structure according to the specific product structure and process requirements.

[0003] Currently, the inner slide or inclined ejector of the mold needs to have sufficient distance for parallel sliding. For the inner clip position where the distance is insufficient, the only solution is to modify the design of the product structure, which results in more products or more molds, causing production waste and increased costs. Utility Model Content

[0004] The purpose of this invention is to provide a retractable inner sliding structure that can overcome the shortcomings of current mold inner sliding or inclined ejector, which do not have sufficient distance, leading to increased production costs.

[0005] To achieve the above objectives, a retractable inward positioning structure is provided, including a base, with support blocks fixedly connected to the left and right ends of the upper part of the base, a template one fixedly connected to the upper side of the support blocks, and a template two movably connected to the upper side of the template one. An ejector plate is disposed between the two support blocks. The lower side of template one has four circular holes and four T-shaped holes. A circular rod is disposed inside each of the four circular holes, and a spring is disposed outside each circular rod. A T-slot plate is fixedly connected to the inner side of each T-shaped hole, and an inner slider is rotatably connected to the upper side of the T-slot plate. The product is movably connected to the inner side of the upper part of template two. This structure allows for stable demolding in situations where mold space is insufficient, replacing traditional parallel inner sliders and angled ejectors.

[0006] According to the aforementioned retractable inward positioning structure, a first fixing block is fixedly connected to the front and rear sides of the template, and a second fixing block is fixedly connected to the front and rear sides of the ejector plate. The first fixing block and the second fixing block are slidably connected, which facilitates the sliding of the first fixing block and the second fixing block.

[0007] According to the aforementioned retractable inner positioning structure, the upper end of the round rod is fixedly connected to the second template, the lower end of the round rod is fixedly connected to the ejector plate, and the round rod is slidably connected to the first template. This facilitates the sliding of the round rod.

[0008] According to the aforementioned retractable inner positioning structure, the lower end of the spring is fixedly connected to the ejector plate, and the upper end of the spring is fixedly connected to the template. This facilitates the connection of the spring.

[0009] According to the aforementioned retractable inner sliding structure, the inner slider is slidably connected to the product, facilitating product detachment.

[0010] The present invention has the following beneficial effects: Compared with the prior art, the arrangement of template one, template two, ejector plate, round rod, spring, T-slot plate and inner slider can achieve the integrity of the product structure without disassembling parts, reduce the number of parts and molds, and can overcome the defects of insufficient mold space and inability to make commonly used parallel inner sliders and inclined ejectors.

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0014] Reference Figure 1-3This utility model discloses a retractable inward positioning structure, comprising a base 1, with support blocks 2 fixedly connected to the left and right ends of the upper part of the base 1, a template 3 fixedly connected to the upper side of the support blocks 2, a template 4 movably connected to the upper side of the template 3, a pin plate 6 disposed between the two support blocks 2, and four round holes 8 and T-shaped holes 11 opened on the lower side of the template 3. A round rod 9 is disposed inside each of the four round holes 8, and a spring 10 is disposed outside the round rod 9. A T-slot plate 12 is fixedly connected to the inner side of the T-shaped hole 11. The upper side is rotatably connected to the inner slider 13, the upper inner side of the template 2 4 is movably connected to the product 14, the front and rear sides of the template 1 3 are fixedly connected to the fixing block 1 5, the front and rear sides of the ejector plate 6 are fixedly connected to the fixing block 2 7, the fixing block 1 5 and the fixing block 2 7 are slidably connected, the upper end of the round rod 9 is fixedly connected to the template 2 4, the lower end of the round rod 9 is fixedly connected to the ejector plate 6, the round rod 9 and the template 1 3 are slidably connected, the lower end of the spring 10 is fixedly connected to the ejector plate 6, the upper end of the spring 10 is fixedly connected to the template 1 3, and the inner slider 13 and the product 14 are slidably connected.

[0015] When the operator uses this device to remove product 14, the ejector plate 6 is driven by the ejection system of the mold (not shown in the figure). The ejector plate 6 compresses the spring 10 and moves the round rod 9. At the same time, the round rod 9 moves the template 2 4. Simultaneously, the ejector plate 6 slides the fixing block 2 7 outside the fixing block 1 5. While the template 2 4 is pushed by the round rod 9, the inner slider 13 slides inside the product 14 until the inner slider 13 completely disengages from the undercut of the product 14, allowing the product 14 to be ejected. The arrangement of template 1 3, template 2 4, ejector plate 6, round rod 9, spring 10, T-slot plate 12, and inner slider 13 ensures the integrity of the product 14 structure without disassembly, reducing the number of parts and molds. It can also address the defects of insufficient mold space, where it is impossible to make commonly used parallel inner sliders 13 and angled ejectors.

[0016] Working principle: When using the device to demold product 14, the operator uses the ejection system of the mold (not shown in the figure) to push the ejector plate 6. Since the two ends of the spring 10 are connected to the ejector plate 6 and the first template 3 respectively, when the ejector plate 6 is pushed, it will compress the spring 10 and drive the round rod 9 to separate the first template 3 from the second template 4. The push of the ejector plate 6, along with the round rod 9, separates the first template 3 from the second template 4. At the same time, the T-slot plate 12 drives the inner slider 13 to slide until the inner slider 13 is completely disengaged from the undercut of product 14, so that product 14 can be ejected.

[0017] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
