Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold with an internal clamping structure. Background Technology

[0002] Molds are tools used for molding and processing, capable of shaping materials into products of specific shapes, and are widely used in industrial production. Silicone glass bottles are containers that combine the elasticity and explosion-proof properties of silicone with the acid and heat resistance of glass. During the bottle external injection molding process, the mold's clamping structure plays a crucial role in ensuring that the silicone is evenly and precisely coated onto the glass bottle surface. Traditional clamping structures typically achieve fixation by clamping the bottle body or bottom. However, when both the bottle body and bottom need to be completely coated with silicone, traditional clamping methods can prevent proper silicone injection at the clamping points, thus affecting the product's integrity and quality. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mold with an internal clamping structure, which can internally clamp the bottle body when the mold is closed, ensuring that the bottle body remains stable during the glue injection process, while not affecting the glue injection effect of the bottle body.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A mold with an internal clamping structure includes: a lower template, a plurality of slider structures disposed on the lower template, an internal clamping structure disposed on the lower template, and a reset structure for resetting the internal clamping structure. The slider structures together enclose a molding cavity. When the slider structures slide to close the mold, one end of the internal clamping structure is pressed down so that the other end of the internal clamping structure abuts against the inner wall of the bottle to be covered. When the slider structures slide to open the mold, the reset structure moves the internal clamping structure away from the inner wall of the bottle.

[0006] According to some embodiments of the present invention, the inner clamping structure includes a clamping block, a rotating structure disposed on the clamping block, and a pressing structure for pushing the clamping block to rotate, wherein the lower template has a first groove for accommodating the clamping block.

[0007] According to some embodiments of the present invention, the clamping block includes a first swing rod for extending into the bottle body and a second swing rod connected to the first swing rod, the rotating structure is disposed at the connection between the first swing rod and the second swing rod, and an included angle is formed between the first swing rod and the second swing rod.

[0008] According to some embodiments of the present invention, the rotating structure includes rotating shaft blocks disposed on both sides of the connection between the first swing rod and the second swing rod, and the lower template is provided with a second groove that cooperates with the rotating shaft blocks.

[0009] According to some embodiments of this utility model, the pressing structure is a third swing rod vertically arranged at the end of the second swing rod, and the top end of the third swing rod extends upward beyond the upper surface of the lower template.

[0010] According to some embodiments of the present invention, the bottom of the slider structure has a guide groove for guiding the third swing rod to gradually press down, and the guide groove gradually slopes upward along the mold closing direction of the slider structure.

[0011] According to some embodiments of the present invention, the reset structure includes an elastic structure disposed on the other side of the second swing rod opposite to the third swing rod, one end of the elastic structure abutting against the bottom of the second swing rod, and the other end abutting against the bottom of the first groove.

[0012] According to some embodiments of the present invention, the clamping block includes an abutment portion located at its top for buffering contact with the inner sidewall of the bottle.

[0013] According to some embodiments of the present invention, the abutting part includes a vertically arranged roller and a roller shaft, the roller shaft being fixed to the top of the clamping block.

[0014] According to some embodiments of this utility model, the lower template is further provided with an annular fixing structure for fixing the bottle mouth of the bottle body.

[0015] This utility model has at least the following beneficial effects:

[0016] When the slider structure is closed, pressing one end of the inner clamping structure causes the other end to abut against the inner wall of the bottle to be covered. This simultaneous mold closing and contact with the inner wall simplifies the structure, increases clamping speed, and ensures bottle stability during molding. The clamping force acts on the inner wall of the bottle, ensuring unobstructed outer contours and allowing for one-time encapsulation of the entire bottle body, offering wide adaptability. The reset structure ensures the inner clamping block quickly disengages from the bottle upon mold opening, reducing manual intervention and preventing damage and deformation.

[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are 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.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a mold with an internal clamping structure, such as... Figure 1-5 As shown, it includes: a lower template 1, multiple slider structures 2 disposed on the lower template 1, an inner clamping structure 3 disposed on the lower template 1, and a reset structure 4 for resetting the inner clamping structure 3. The slider structures 2 together enclose the molding cavity 201. When the slider structure 2 slides to close the mold, it can press down one end of the inner clamping structure 3 so that the other end of the inner clamping structure 3 abuts against the inner sidewall of the bottle to be covered. When the slider structure 2 slides to open the mold, the reset structure 4 can move the inner clamping structure 3 away from the inner sidewall of the bottle.

[0026] The bottle is placed on the lower template 1, and together with multiple slider structures 2, they enclose the outer side of the bottle to form a molding cavity 201. This allows for precise control of the thickness and shape of the silicone or plastic coating on the bottle's exterior, enabling efficient molding of complex-shaped products. It is also adaptable to various coating requirements for bottles made of different materials, offering wide applicability. The design of the inner clamping structure 3 ensures that when the slider structure 2 slides and closes the mold, pressing down on one end of the inner clamping structure 3 causes the other end to rotate or slide against the inner wall of the bottle to be coated, ensuring the stability of the bottle during molding and effectively preventing displacement. Since the inner clamping structure 3 is used to clamp the inner wall of the bottle, each inner clamping structure 3 is distributed circumferentially along the inner side of the bottle, facilitating contact with the inner wall in different directions and improving contact stability.

[0027] The bottle mouth is placed downwards on the lower mold plate 1 and then formed with the slider structure 2. The inner clamping structure 3 has a unique characteristic: one end of it, which abuts against the inner wall of the bottle, extends upwards from the bottle mouth into the internal space of the bottle body from the inside of the lower mold plate 1; the other end of the inner clamping structure 3 is located inside the lower mold plate 1 to avoid the placement of the bottle mouth, and then extends outwards from the lower mold plate 1 to a position where it can touch the slider structure 2. The inner clamping structure 3 is automatically triggered when the slider closes the mold. The pressing method can be to press one end of the inner clamping structure 3 downwards from the lower mold plate 1 or to press one end of the inner clamping structure 3 laterally, so that the other end of the inner clamping structure 3 abuts against the inner wall of the bottle by sliding or rotating. The clamping force acts on the inner wall of the bottle, and the entire outer contour of the forming cavity 201 is unobstructed, allowing the colloid to cover the bottle mouth in one go with good integrity. The mechanical clamping method is simple and reliable, requiring no additional hydraulic cylinders or wedges, reducing additional structural components, lowering mold thickness, simplifying operation, reducing costs, saving independent clamping time, and improving efficiency. The presence of a reset structure 4, such as a reset spring, ensures that the inner clamping structure 3 can quickly detach the inner clamping block 301 from the bottle body and move away from the inner wall of the bottle body when the slider structure 2 slides open the mold. This reduces the need for additional demolding structures, reduces manual intervention, and avoids damage and deformation caused by picking.

[0028] In some embodiments, such as Figure 3-4 As shown, the inner clamping structure 3 includes a clamping block 301, a rotating structure 302 disposed on the clamping block 301, and a pressing structure 303 for pushing the clamping block 301 to rotate. The lower template 1 has a first groove 101 for accommodating the clamping block 301.

[0029] The inner clamping structure 3 achieves a rotating clamping function through the cooperation of the clamping block 301, the rotating structure 302, and the pressing structure 303. The clamping block 301 is set in the first groove 101 of the lower template 1. The width of the first groove 101 is greater than the width of the overall trajectory of the clamping block 301 when rotating. The slider structure 2 can press down or laterally on the pressing structure 303, thereby pushing one end of the clamping block 301 so that the other end rotates with the rotating structure 302 as the fulcrum, and then abuts against the inner wall of the bottle. Furthermore, the pressing structure 303 can be directly set at the bottom of the slider structure 2, pushing the clamping block 301 as the mold closes. The rotating structure 302 on the clamping block 301 realizes the rotating abutment method. The rotation fulcrum is set at the bottle mouth, so that even a structure with a small bottle mouth and a wide bottle body can achieve abutment and clamping. The rotation method can further reduce the displacement of the clamping block 301 at the bottle mouth and further utilize space.

[0030] Furthermore, such as Figure 3 As shown, the clamping block 301 includes a first swing rod 304 for extending into the bottle body and a second swing rod 305 connected to the first swing rod 304. The rotating structure 302 is disposed at the connection between the first swing rod 304 and the second swing rod 305, and an included angle is formed between the first swing rod 304 and the second swing rod 305.

[0031] The clamping block 301 consists of a first swing rod 304 and a second swing rod 305, forming an angle between them, specifically not exceeding 180°. A rotating structure 302 is located at their connection point. When the end of the second swing rod 305 is pushed by the pressing structure 303, the clamping block 301 can swing flexibly around the rotating structure 302 as a fulcrum, allowing the top of the first swing rod 304 to abut against the inner wall of the bottle. In this embodiment, the angle between the first swing rod 304 and the second swing rod 305 is 90°, making the clamping block 301 L-shaped. The L-shaped structure makes the overall structure of the clamping block 301 horizontally and vertically straight, simplifying processing and facilitating the installation and setting of the reset structure 4 and the pressing structure 303. The pressing structure 303 can be either a separate component located on the end of the second swing rod 305 or an integral component located on the end of the second swing rod 305.

[0032] Furthermore, such as Figure 2-3 As shown, the rotating structure 302 includes rotating shaft blocks 306 disposed on both sides of the connection between the first swing rod 304 and the second swing rod 305, and the lower template 1 is provided with a second groove 102 that cooperates with the rotating shaft blocks 306.

[0033] The cooperation between the pivot block 306 and the second groove 102 provides a reliable fulcrum for the clamping block 301, ensuring that the clamping block 301 can rotate accurately and smoothly under the push of the slider structure 2, thereby achieving stable contact and clamping of the inner wall of the bottle. The pivot block 306 has a simple and effective structure, and the second groove 102 limits the rotation of the pivot block 306 to maintain rotational stability.

[0034] Furthermore, such as Figure 3-4 As shown, the pressing structure 303 is a third swing rod 307 vertically arranged at the end of the second swing rod 305, and the top end of the third swing rod 307 extends upward to the upper surface of the lower template 1.

[0035] The third swing rod 307 is fixed to the end of the second swing rod 305. The top of the third swing rod 307 extends upwards from the upper surface of the lower template 1, meaning the lower template 1 has a vertically arranged groove that matches the third swing rod 307. The vertically arranged third swing rod 307 facilitates contact with the slider structure 2 and is pressed downwards by it, allowing the slider structure 2 to directly act on the top of the third swing rod 307 during mold closing. The vertical downward pressing action pushes the second swing rod 305, thereby causing the first swing rod 304 to rotate around the rotating structure 302 as a fulcrum, realizing the clamping action of the clamping block 301. The third swing rod 307 and the second swing rod 305 can be directly fixed or fixed by hinge. In this embodiment, the third swing rod 307 is directly fixed to the end of the second swing rod 305, and together with the first swing rod 304, they form a J-shaped shape. The horizontal and vertical structure facilitates processing and also facilitates the deduction of the rotation path, providing a clear force transmission path and ensuring the efficiency and reliability of the clamping action.

[0036] Furthermore, such as Figure 4-5 As shown, the bottom of the slider structure 2 has a guide groove 202 for guiding the third swing rod 307 to gradually press down, and the guide groove 202 gradually tilts upward along the mold closing direction of the slider structure 2.

[0037] The guide groove 202 at the bottom of the slider structure 2 gradually slopes upwards along the mold closing direction, thereby guiding the third swing rod 307 to gradually press down during mold closing. This makes the clamping action of the clamping block 301 more stable and gradual, avoiding impact and damage that may be caused by instantaneous force application. Furthermore, the bottom surface of the slider structure 2, which abuts against the top of the third swing rod 307 after mold closing, is horizontal, improving the stability of internal clamping. This structure is simple and easy to implement, requiring no complex power unit or additional control mechanism, thus reducing the manufacturing cost and maintenance difficulty of the mold.

[0038] Furthermore, such as Figure 3-5As shown, the reset structure 4 includes an elastic structure 401 disposed on the other side of the second swing rod 305 relative to the third swing rod 307. One end of the elastic structure 401 abuts against the bottom of the second swing rod 305, and the other end abuts against the bottom of the first groove 101.

[0039] The elastic structure 401, including springs and spring sheets, provides a reliable restoring force to the clamping block 301, ensuring that the bottom of the second swing rod 305 is simultaneously lifted when the slider structure 2 opens, allowing the end of the first swing rod 304 to quickly and smoothly detach from the inner wall of the bottle and return to its initial position. The elastic structure 401 is positioned relative to the third swing rod 307, and when the slider structure 2 closes, it is compressed downwards by the third swing rod 307, reducing offset. The presence of the elastic structure 401 improves the reliability and stability of the restoring action.

[0040] Furthermore, such as Figure 3 As shown, the clamping block 301 includes an abutment portion 308 located at its top for cushioning abutment against the inner wall of the bottle.

[0041] The abutment portion 308 can be made of materials such as elastic rubber pads, which can ensure close contact between the clamping block 301 and the bottle body without damaging the inner wall of the bottle body, thereby providing stable support and fixation for the bottle body during the molding process. Furthermore, the abutment portion 308 can be configured in different shapes to adapt to bottles of different shapes and sizes, enhancing the applicability and flexibility of the mold.

[0042] Furthermore, such as Figure 3 As shown, the abutment part 308 includes a vertically arranged roller 309 and a roller 310, with the roller 310 vertically fixed to the top of the clamping block 301.

[0043] The roller 309 can rotate freely around the roller 310, changing the contact mode between the clamping block 301 and the inner wall of the bottle from sliding friction to rolling friction. This greatly reduces friction, minimizes wear and scratches on the bottle surface, and improves the smoothness and stability of the clamping action. The rotation of the roller 309 can also adapt to minor unevenness on the inner wall of the bottle, further enhancing the reliability of the clamping.

[0044] In some embodiments, such as Figure 1 , 4 As shown in Figure 5, the lower template 1 is also provided with an annular fixing structure 5 for fixing the bottle mouth of the bottle body.

[0045] The annular fixing structure 5 is specifically an annular groove fixing structure that matches the shape of the bottle mouth. It is mainly used to fix the bottle mouth, achieve the initial positioning of the bottle body, prevent interference with the inner clamping structure 3 or the slider structure 2, and improve the molding stability.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
