Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to a mold structure that facilitates the disassembly of the inner sliding block. Background Technology

[0002] In the field of injection molding, internal pull-out slider mechanisms are commonly used to create undercuts, grooves, or other complex structures inside molded products. In traditional molds, ejector pins may be inserted within the internal pull-out slider. These ejector pins eject the molded product, while the internal pull-out slider is responsible for forming the internal features of the product. However, when the internal pull-out slider needs repair, replacement, or maintenance, the presence of ejector pins significantly increases the operational difficulty. Because the ejector pins penetrate the internal pull-out slider and can only move vertically, the slider cannot be directly pulled out laterally. Furthermore, other ejection structures on the front mold (such as angled ejectors) restrict the upward movement of the front mold platen, preventing it from moving significantly upward and causing the ejector pins to separate from the slider. Therefore, this usually requires removing most of the ejection structure parts (such as angled ejectors and straight ejectors) from the entire front mold to move the front mold platen upward over a large area, allowing the ejector pins to separate from the internal pull-out slider. The internal pull-out slider then needs to be disassembled for repair and machining. After repair and machining, the entire front mold needs to be reinstalled, which is time-consuming and labor-intensive. Utility Model Content

[0003] In order to overcome the above-mentioned technical defects, the present invention provides a mold structure that facilitates the disassembly of the inner sliding block, which aims to solve at least one of the problems in the background art.

[0004] This utility model is implemented according to the following technical solution:

[0005] This utility model discloses a mold structure that facilitates the disassembly of the inner sliding block, comprising:

[0006] The lower fixing plate has a first through hole;

[0007] A ejector base plate, located above the lower fixing plate, has a second through hole;

[0008] Ejector plate, which is located above the ejector base plate;

[0009] The second sealing block is detachably connected to the bottom of the ejector pin base plate and is used to seal the second through hole;

[0010] A front template is located above the ejector plate, and an inner sliding block is slidably provided inside the front template;

[0011] A ejector pin is inserted into the ejector pin panel, the ejector pin is inserted upward through the inner sliding block, and the bottom of the ejector pin abuts against the second sealing block;

[0012] In the vertical projection direction, the ejector pin falls completely within the outline of the second through hole, and the second through hole and the second sealing block fall completely within the outline of the first through hole.

[0013] Compared with the prior art, this utility model, through the detachable connection between the second sealing block and the ejector pin base plate, only requires removing the second sealing block from below the lower fixed plate. Without the support of the second sealing block, the ejector pin will automatically slide down under gravity, achieving separation of the ejector pin and the inner sliding block. This allows the ejector pin to be removed separately from below the lower fixed plate, eliminating obstacles to the outward movement of the inner sliding block. Thus, the inner sliding block can be easily removed. Only the ejector pin needs to be removed; there is no need to remove other ejector components for repair and processing, greatly improving work efficiency.

[0014] In a preferred embodiment, the second through hole adopts a stepped hole structure, the second sealing block is embedded in the second through hole, and the second sealing block does not protrude from the bottom surface of the ejector pin base plate.

[0015] In a preferred embodiment, a second step portion is provided in the second through hole, and a second threaded hole is provided at the second step portion for screw fasteners to pass through and threadedly connect the second sealing block and the second step portion.

[0016] In a preferred embodiment, a second insertion hole is connected to the outside of the second through hole.

[0017] In a preferred embodiment, the mold structure that facilitates the disassembly of the inner sliding block further includes a first sealing block, which is detachably connected to the bottom of the lower fixed plate and is used to cover the first through hole.

[0018] In a preferred embodiment, the first through hole adopts a stepped hole structure, the first sealing block is embedded in the first through hole, and the first sealing block does not protrude from the bottom surface of the lower fixing plate.

[0019] In a preferred embodiment, a first step portion is provided in the first through hole, and a first threaded hole is provided at the first step portion for screw fasteners to pass through the first sealing block and threadedly connect with the first step portion.

[0020] In a preferred embodiment, a first insertion hole is connected to the outside of the first through hole. Attached Figure Description

Detailed Implementation

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0031] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] To facilitate understanding of this utility model, Figure 2 The first block 800 and the second block 400 are omitted. Figure 4 The second sealing block 800 was disassembled from the mold.

[0033] See Figures 1 to 4 The utility model discloses a mold structure that facilitates the disassembly of the inner sliding block, comprising:

[0034] The lower fixing plate 100 has a first through hole 110;

[0035] The ejector base plate 200 is located above the lower fixing plate 100, and the ejector base plate 200 has a second through hole 210;

[0036] Ejector panel 300 is located above ejector base plate 200;

[0037] The second sealing block 400 is detachably connected to the bottom of the ejector pin base plate 200 and is used to seal the second through hole 210;

[0038] The front template 500 is located above the ejector plate 300, and an inner sliding block 600 is slidably disposed inside the front template 500.

[0039] The ejector pin 700 is inserted into the ejector pin panel 300, the ejector pin 700 is inserted upward through the inner sliding block 600, and the bottom of the ejector pin 700 abuts against the second sealing block 400;

[0040] In the vertical projection direction, the ejector pin 700 falls completely within the outline of the second through hole 210, and the second through hole 210 and the second sealing block 400 fall completely within the outline of the first through hole 110.

[0041] Compared with the prior art, this utility model, through the detachable connection between the second sealing block 400 and the ejector base plate 200, only requires removing the second sealing block 400 from below the lower fixing plate 100. Without the support of the second sealing block 400, the ejector pin 700 will automatically slide down under gravity, achieving separation of the ejector pin 700 from the inner sliding block 600. This allows the ejector pin 700 to be removed separately from below the lower fixing plate 100, eliminating obstacles to the outward movement of the inner sliding block 600. Thus, the inner sliding block 600 can be easily removed. Only the ejector pin 700 needs to be removed; there is no need to remove other ejector components for repair and processing, greatly improving work efficiency.

[0042] In one embodiment, the second through hole 210 adopts a stepped hole structure, and the second sealing block 400 is embedded in the second through hole 210. The second sealing block 400 does not protrude from the bottom surface of the ejector pin base plate 200. The stepped hole structure provides a precise embedding position for the second sealing block 400. The fact that the second sealing block 400 does not protrude from the bottom surface of the ejector pin base plate 200 ensures that there is no protrusion interference between the ejector pin base plate 200 and the lower fixed plate 100 when the mold is closed, thus avoiding the problem of uneven mold closing clearance caused by the protrusion of the second sealing block 400.

[0043] Furthermore, a second step portion 211 is provided within the second through hole 210, and a second threaded hole 212 is provided at the second step portion 211 for a screw fastener to be inserted into the second sealing block 400 and threadedly connected to the second step portion 211. By providing a threaded hole in the second step portion 211 and using a screw fastener, a rigid threaded connection is achieved between the second sealing block 400 and the ejector pin base plate 200, ensuring support for the ejector pin 700.

[0044] Furthermore, the outer side of the second through hole 210 is connected to a second insertion hole 220. The second insertion hole 220 provides a direct access channel for fingers or tools (such as pin pullers, screwdrivers, etc.), allowing external force to be quickly applied to the second sealing block 400 through the second insertion hole 220, avoiding the operational difficulties caused by narrow space in traditional disassembly methods, and significantly shortening the disassembly and assembly time.

[0045] In one embodiment, the mold structure facilitating the disassembly of the inner sliding block further includes a first sealing block 800, which is detachably connected to the bottom of the lower fixed plate 100 and used to cover the first through hole 110. The first sealing block 800, by detachably covering the first through hole 110 of the lower fixed plate 100, effectively prevents external impurities (such as dust and metal shavings) from entering the mold, ensuring long-term stable operation of the mold. During maintenance, simply removing the first sealing block 800 completely opens the first through hole 110, exposing the second sealing block 400, making the operation simple and convenient.

[0046] Furthermore, the first through hole 110 adopts a stepped hole structure, and the first sealing block 800 is embedded in the first through hole 110. The first sealing block 800 does not protrude from the bottom surface of the lower fixing plate 100. The fact that the first sealing block 800 does not protrude from the bottom surface of the lower fixing plate 100 avoids the problem of uneven gaps caused by protrusions during mold installation.

[0047] Furthermore, a first step portion 111 is provided within the first through hole 110, and a first threaded hole 112 is provided at the first step portion 111 for a screw fastener to be inserted into the first sealing block 800 and threadedly connected to the first step portion 111. By providing a threaded hole in the first step portion 111 and using a screw fastener, a rigid threaded connection is achieved between the first sealing block 800 and the lower fixing plate 100, thereby sealing the first through hole 110.

[0048] Furthermore, the outer side of the first through hole 110 is connected to a first insertion hole 120. The first insertion hole 120 provides a direct access channel for fingers or tools (such as pin pullers, screwdrivers, etc.), allowing external force to be quickly applied to the first sealing block 800 through the first insertion hole 120, avoiding the operational difficulties caused by narrow space in traditional disassembly methods, and significantly shortening the disassembly and assembly time.

[0049] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
