Description

Technical Field

[0001] This utility model relates to the field of slider mold opening technology, and in particular to a slider internal submerged rubber structure. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] For some products, the front is the main surface to be controlled. The mold design for these products has slides on all four sides, and glue cannot be injected into the front surface. In order to avoid leaving glue marks on the front surface in the middle of the product, it is necessary to design a mold structure that can prevent glue from being injected into the front, avoid adverse effects on the appearance of the front of the product, reduce the defect rate of the product, reduce the labor intensity of workers, and reduce production costs. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a slider with an internal glue-retaining structure. This structure is simple, easy to use, and can effectively reduce the impact of glue residue on the product's appearance, ensuring product appearance quality, improving production efficiency, and reducing production costs.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] A submerged rubber structure within a slider includes a slider, a spade base movably disposed within the slider and driving the slider, and a sprue ejector pin inserted into the slider and driven by the slider. An injection cavity is formed at the upper part of the slider, directly above the sprue ejector pin, with the opening of the injection cavity facing upwards. The inner wall of the injection cavity forms the outer surface of the product. An integrally inclined guide groove is formed at the end of the slider away from the injection cavity. The slider slides vertically within the guide groove, driving the slider to move horizontally.

[0007] As a further improvement of this utility model, the guide drive groove is inclined from the upper outside to the lower inside, and the upper part of the shovel base is formed with a drive slope that matches the guide drive groove and is inclined from the upper outside to the lower inside as a whole.

[0008] As a further improvement of this utility model, the upper part of the shovel base away from the driving inclined surface forms a driving limiting block that is integrally right-angled triangle with the right-angled side sliding vertically in the guide driving groove. The end of the guide driving groove away from the water outlet pin forms a driving limiting groove that matches the driving limiting block.

[0009] As a further improvement of this utility model, the top of the shovel base away from the sprue pin has a driving insertion inclined guide surface that extends obliquely downward from the direction of the sprue pin.

[0010] As a further improvement of this utility model, the top of the sprue pin is formed with a lifting part that is integrally shaped like a frustum and protrudes upward.

[0011] As a further improvement of this utility model, it also includes a pin seat disposed at the lower part of the sprue pin, and the sprue pin slides on the upper end of the pin seat.

[0012] As a further improvement of this utility model, the upper part of the ejector seat is formed with an integrally T-shaped ejector movable groove, and the bottom end of the sprue ejector is formed with an outwardly protruding ring platform that slides in the ejector movable groove.

[0013] As a further improvement of this utility model, a downwardly protruding arc surface is formed on the lower end surface of the ring platform.

[0014] As a further improvement of this utility model, a through groove for inserting a water supply pin is formed on the slider below the injection molding cavity.

[0015] As a further improvement of this utility model, the lower end of the through groove is formed with a pin insertion inclined guide surface that extends obliquely from the inner upper part to the outer lower part.

[0016] The beneficial effects of this utility model are as follows:

[0017] By configuring the submerged plastic structure within the slider as including a slider, a spade base movably disposed within the slider and driving the slider, and a sprue ejector pin inserted into the slider and driven by the slider, an injection cavity is formed at the upper part of the slider, directly above the sprue ejector pin. The opening of the injection cavity faces upwards, and the inner wall of the injection cavity forms the outer surface of the product. An integrally inclined guide groove is formed at the end of the slider away from the injection cavity. The slider slides vertically within the guide groove, driving it to move horizontally. The melted plastic is injected through the opening of the injection cavity and injection molded within it. Because the inner wall of the injection cavity forms the outer surface of the product, the entire injection molded part has an inverted structure, with the plastic feed point at the bottom of the injection molded part. This avoids front-side injection, preventing adverse effects on the product's appearance, reducing product defect rates, decreasing worker labor intensity, and lowering production costs. During mold opening, the shovel base is vertically inserted into the guide groove. Because the guide groove is an inclined structure, the shovel base, vertically inserted into the guide groove, drives the slider to move horizontally, causing the injection cavity in the slider to disengage from the injection molding machine nozzle. The sprue ejector pin is driven by the slider to move synchronously, and under the drive of the external control mechanism, it moves upward to eject the injection molded part from the mold. The entire structure is simple and easy to use, effectively reducing the impact of glue residue on the product's appearance, ensuring product appearance quality, and improving mold opening efficiency.

[0027] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0028] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Please refer to Figures 1 to 7This utility model embodiment provides a submerged glue structure inside a slider 1, including a slider 1, a shovel base 2 movably disposed inside the slider 1 and driving the slider 1, and a sprue ejector pin 3 pushed into the slider 1 and driven by the slider 1. An injection cavity 11 is formed at the upper part of the slider 1, directly above the sprue ejector pin 3. The opening of the injection cavity 11 faces upward, and the inner wall of the injection cavity 11 is the outer surface of the product. An integrally inclined guide groove 12 is formed at the end of the slider 1 away from the injection cavity 11. The slider 1 slides vertically in the guide groove 12 and is driven to move horizontally.

[0032] After melting, the plastic is injected through the opening of the injection cavity 11 and molded within it. Since the inner wall of the injection cavity 11 forms the product's outer surface, the entire molded part is inverted, with the plastic feed point at the bottom. This avoids frontal injection, preventing adverse effects on the product's appearance, reducing defect rates, minimizing labor intensity, and lowering production costs. During mold opening, the spade base 2 is vertically inserted into the guide groove 12. Because the guide groove 12 is inclined, the spade base 2 drives the slider 1 to move horizontally, causing the injection cavity 11 in the slider 1 to disengage from the injection molding machine nozzle. The sprue ejector pin 3 is driven by the slider 1 to move synchronously and, under the drive of an external control mechanism, moves upward to eject the molded part. The entire structure is simple and easy to use, effectively reducing the impact of residual glue marks on the product's outer surface, ensuring product appearance quality, and improving mold opening efficiency. By setting the sprue ejector pin 3 to be placed on the injection molded part, the air bubbles caused by the injection molding process are effectively reduced, and the solidified material is held back during injection molding to prepare for subsequent production, keep the mold unobstructed, and thus ensure the molding quality and appearance quality of the injection molded part.

[0033] The specific method by which the shovel base 2 drives the slider 1 to move is as follows: Figures 2 to 5As shown, the guide groove 12 is inclined from the upper outside to the lower inside. The upper part of the shovel base 2 has a driving slope 21 that matches the guide groove 12 and is inclined from the upper outside to the lower inside. When the shovel base 2 is placed into the guide groove 12, its driving slope 21 first contacts the inner wall of the inclined guide groove 12. Under the inclined guiding action of the guide groove 12 and the driving slope 21, the shovel base 2, vertically placed in the slider 1, can drive the slider 1 to move horizontally, thereby causing the injection cavity 11 in the slider 1 to disengage from the injection molding machine nozzle. The sprue ejector pin 3 is driven by the slider 1 to move synchronously, and under the drive of the external control mechanism, it moves upward to eject the injection molded part and open the mold. The entire structure is simple and clear, easy to use, and ensures precise driving of the slider 1 by the shovel base 2, improving production efficiency.

[0034] Preferably, in order to make the shovel base 2 more accurately drive the slider 1, Figure 2 , Figure 4 as well as Figure 5 As shown, the upper part of the shovel base 2, away from the driving inclined surface 21, forms a driving limiting block 22 that is integrally right-angled triangle with its right-angled side sliding vertically within the guide driving groove 12. The end of the guide driving groove 12 away from the sprue pin 3 forms a driving limiting groove 121 that matches the driving limiting block 22. When the shovel base 2 is placed into the slider 1, the driving limiting block 22 is simultaneously placed into the driving limiting groove 121. Because the right-angled side of the driving limiting block 22 slides vertically within the guide driving groove 12, and the inner wall of the driving limiting groove 121 near the driving limiting block 22 is also vertical, the corresponding vertical structure can more easily restrict the stroke of the slider 1 and the shovel base 2 in the inclined guide driving groove 12, enabling the shovel base 2 to perform precise vertical movement and the slider 1 to perform horizontal movement. This further ensures the precise driving of the slider 1 by the shovel base 2 and improves production efficiency.

[0035] Preferably, to make it easier for the shovel base 2 to be placed into the guide groove 12, such as... Figures 1 to 2 as well as Figure 5 As shown, the top of the shovel base 2, away from the sprue pin 3, has a driving insertion inclined guide surface 23 that extends downward and outward from the upper part of the direction towards the sprue pin 3. When the shovel base 2 is inserted into the guide drive groove 12, the driving insertion inclined guide surface 23 on it first contacts the inner wall of the guide drive groove 12. Under the inclined guiding action of its upward extension downward and outward from the direction towards the sprue pin 3, the shovel base 2 can more easily and accurately enter the middle of the guide drive groove 12, thereby improving the efficiency and accuracy of inserting into the slider 1 and driving the slider 1, and improving production efficiency.

[0036] Regarding the specific structure of the sprue ejector pin 3, as follows: Figure 2 as well as Figure 6 As shown, the top of the sprue ejector pin 3 has an upwardly protruding, frustum-shaped lifting part 31. By setting the lifting part 31 to a frustum structure, the lifting part 31 can be inserted into the position where air bubbles are easily generated due to the large slope and large diameter of the bottom of the main runner when injection molding materials such as acrylic and PC transparent materials. This effectively reduces air bubbles caused by production during injection molding, and holds the solidified material during injection molding, preparing for subsequent production, keeping the mold unobstructed, and thus ensuring the molding quality and appearance quality of the injection molded parts.

[0037] Preferred, such as Figures 1 to 2 as well as Figure 7 As shown, the submerged rubber structure inside the slider also includes a pin seat 4 disposed at the lower part of the sprue pin 3. The sprue pin 3 slides on the upper end of the pin seat 4, so that when the pin seat 4 drives the sprue pin 3 to move vertically up and down under the action of external force, the sprue pin 3 can also be driven by the slider 1 to move horizontally left and right on the pin seat 4, which is conducive to the cooperation between the components and improves production efficiency.

[0038] The specific method by which the sprue ejector pin 3 slides within the ejector pin seat 4 is as follows: Figures 1 to 2 as well as Figure 7 As shown, the upper part of the ejector seat 4 has an integrally T-shaped ejector movable groove 41, and the bottom end of the sprue ejector 3 has an outwardly protruding annular platform 32 that slides within the ejector movable groove 41. By setting the ejector movable groove 41 as an inverted T-shaped structure, with two pairs of limiting blocks forming at its upper end to limit the movement of the sprue ejector 3, the outwardly protruding structure of the annular platform 32 confines it within the ejector movable groove 41, preventing it from falling off from above. This effectively limits the movement of the sprue ejector 3, allowing it to move only radially in the horizontal direction along the ejector movable groove 41. This improves the accuracy and efficiency of the sprue ejector 3 being driven and effectively prevents it from falling off when driven.

[0039] Preferred, such as Figure 2 as well as Figure 6 , Figure 7As shown, in order to make the sprue ejector pin 3 slide more smoothly on the ejector seat 4, a downwardly protruding arc surface 321 is formed on the lower end surface of the ring platform 32. By setting the downwardly protruding arc surface 321 at the lower end of the ring platform 32, the contact area between the lower end of the ring platform 32 and the inner wall of the ejector movable groove 41 is reduced. This effectively reduces the friction between the ring platform 32 and the ejector movable groove 41 while not affecting the limiting of the ejector movable groove 41 on the ring platform 32. As a result, the sprue ejector pin 3 slides more smoothly on the ejector seat 4, improving the accuracy and efficiency of the sprue ejector pin 3 being driven, thereby improving production efficiency.

[0040] Regarding the specific method of inserting the sprue pin 3 into the slider 1, as follows: Figure 2 as well as Figure 4 As shown, a through groove 13 is formed on the slider 1 below the injection cavity 11, into which the sprue ejector pin 3 is inserted. The through groove 13 can be a diversion channel, allowing plastic to be injected first before the sprue ejector pin 3 is inserted, or it can simply be used for the sprue ejector pin 3; the configuration can be adjusted according to the actual situation. The sprue ejector pin 3 moves up and down within the through groove 13, thus being limited by the through groove 13 to prevent it from shifting during vertical movement. This effectively ensures the accuracy and efficiency of the sprue ejector pin 3's operation, thereby improving production efficiency.

[0041] Preferred, such as Figure 2 and Figure 4 As shown, in order to make it easier and more accurate to insert the sprue pin 3 into the through groove 13, the lower end of the through groove 13 is formed with a pin insertion inclined guide surface 131 extending inclinedly from the inner upper to the outer lower. When the sprue pin 3 is inserted into the through groove 13, it first contacts the pin insertion inclined guide surface 131. Under the inclined guiding action of the pin insertion inclined guide surface 131, it is easier and more accurate to insert into the through groove 13, thereby improving the installation efficiency of the submerged rubber structure in the slider 1 and improving production efficiency.

[0042] It should be noted that the slider internal submerged rubber structure disclosed in this utility model is an improvement on a specific structure, but the specific control method is not an innovation of this utility model. The plastics, injection molding machines, and other components involved in this utility model can be general standard parts or components known to those skilled in the art, and their structures, principles, and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
