Description

Technical Field

[0001] This utility model relates to the technical field of football mold body, and in particular to a football skin forming mold. Background Technology

[0002] In the field of football manufacturing, traditional football skin production processes have many limitations. In the early days, they were mostly made by hand sewing or simple splicing, which was inefficient and made it difficult to guarantee product precision and consistency. With the development of technology, football skin mold bodies have emerged. Although existing mold bodies have achieved a certain degree of standardized production, there is still room for improvement in injection molding processes. For example, uneven material distribution during injection molding can lead to inconsistent thickness of the football skin, affecting flight trajectory and durability. At the same time, the demolding process of the mold body often results in surface damage to the product. To solve these problems, it is urgent to develop more advanced injection molding processes for football skin mold bodies, which requires starting from mold body design, injection parameter optimization, and other aspects.

[0003] In the existing technology, due to defects in the structure of the football mold body or defects in the connecting parts between the upper and lower mold bodies, the stability of the mold body is poor, and the surface of the produced football is not smooth or the shape of the football is affected.

[0004] To address the aforementioned issues, an existing patent (publication number: CN207549227U) proposes a football skin forming mold. This mold features hemispherical cavities in both the upper and lower molds, which are then merged into a single spherical cavity. An annular groove communicating with the outermost edge of each hemispherical cavity is formed. The mold core is a hollow sphere, fixedly connected to the upper mold via a connector located within the annular groove. Due to the connector, the mold core is suspended. After the upper mold, lower mold, and mold core are combined, a football-shaped cavity is formed between the mold core and both molds. A guide post is fixedly installed at the lower end of the upper mold. This invention features a simple and reasonable structure, is easy to use, and has a low cost. The upper and lower molds are connected by multiple guide posts and guide holes, effectively enhancing the stability of the mold body. Simultaneously, the connection between the air inlet, guide holes, and air outlet effectively ensures material feeding and gas discharge during the football forming process, thus guaranteeing a smooth and uniform football surface.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in the soccer ball skin mold body, the left and right halves of the mold body are usually used to complete the soccer ball skin structure for injection molding. But when demolding after injection molding, the finished material may adhere to the side of the mold body without a demolding structure, requiring manual intervention and resulting in low efficiency. Furthermore, when demolding the material inside the mold body using a push rod, the pushing speed may be too fast, causing damage to the material skin.

[0006] To address this, a mold for forming the outer skin of a soccer ball is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a football skin forming mold that can solve the problems of low efficiency and poor quality caused by the instability of the existing finished skin due to its dependence on the mold body and the high pressure of the demolding push rod.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a football skin molding mold, including an injection chamber, an injection molding machine movably connected to the right side of the injection chamber, a left mold body movably connected to the left side of the inner side of the injection chamber, a right mold body fixedly connected to the right side of the inner side of the injection chamber, a demolding auxiliary mechanism movably connected to the bottom of both the injection chamber and the injection molding machine, and a demolding buffer mechanism movably connected to the inner side of the injection chamber;

[0009] The demolding auxiliary mechanism includes an injection platform, a support base plate, an adjusting block, and an angle adjusting component. The injection platform is fixedly connected to the bottom of the injection chamber and the injection molder. The support base plate is rotatably connected to the bottom of the injection platform. The angle adjusting component is movably connected to the top of the support base plate. The adjusting block is movably connected to the inner side of the angle adjusting component. The adjusting block is located at the bottom of the injection platform.

[0010] Preferably, the demolding buffer mechanism includes a first electric telescopic platform, a stepped buffer block, a spring assembly, a push rod, and an extension block.

[0011] Preferably, the first electric telescopic platform is located inside the injection molding chamber, the stepped buffer block is movably connected to the right side of the first electric telescopic platform, and the spring assembly is movably connected to the inside of the stepped buffer block.

[0012] Preferably, the push rod is fixedly connected to the right side of the stepped buffer block, and the extension block is fixedly connected to the left side of the left mold body.

[0013] Preferably, the angle adjustment assembly includes a guide rod, a sliding support block, and an electric lead screw.

[0014] Preferably, the guide rod is fixedly connected to the top of the support base plate, the sliding support block is fixedly connected to the left side of the adjusting block, the sliding support block is slidably connected to the outside of the guide rod, the electric lead screw is threadedly connected to the inside of the sliding support block, and the electric lead screw is movably connected to the top of the support base plate.

[0015] Preferably, a second electric telescopic platform is fixedly connected to the left side of the inner side of the injection chamber, a support plate is fixedly connected to the right side of the second electric telescopic platform, the first electric telescopic platform is movably connected to the right side of the support plate, and the left mold body is fixedly connected to the right side of the support plate.

[0016] Preferably, the top of the injection molding platform is movably connected to a guide ramp, the guide ramp is located inside the injection molding chamber, and the front side of the injection molding chamber has a discharge port.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a demolding auxiliary mechanism, can drive the sliding support block to slide along the guide rod through the rotation of the electric screw, thereby allowing the rear adjustment block to enter the gap between the support base plate and the injection platform. Utilizing the characteristic of the inclined surface of one side of the triangular prism of the adjustment block, the top injection platform is squeezed to rotate to an inclined state. Before injection, the internal structure of the injection molder and injection chamber is adjusted into place. In this way, when demolding is completed after injection, the outer skin of the soccer ball falls into the inner side of the left mold body with the demolding structure due to the inclined gravity, and can be demolded smoothly. This effectively avoids the problem of material staying in the right mold body during horizontal injection, which requires manual intervention, and greatly improves injection efficiency. At the same time, different angles can be adjusted to adapt to the production of different models of soccer balls and enhance the injection effect of the injection molder.

[0019] 2. By setting up a demolding buffer mechanism, this application allows the stepped buffer block connected between the push rod and the first electric telescopic platform to contact the extension block on the rear side of the left mold body first when the first electric telescopic push rod moves to the rear side of the mold body for demolding. As it advances, the extension block squeezes the stepped buffer block, causing it to contract. Based on the design of the stepped buffer block nested in a stepped telescopic shape and the inner spring group, the multiple springs in the spring group store energy to generate a push force when compressed, which buffers the speed of the push rod and realizes the stepped advancement of the push rod during demolding. This design effectively avoids damage to the material surface caused by excessive advancement speed, greatly improves product quality, ensures a smooth and safe demolding process, reduces scrap rate, and improves production efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A football skin molding mold includes an injection chamber 1, an injection molding machine 2 movably connected to the right side of the injection chamber 1, a left mold body 3 movably connected to the left side of the inner side of the injection chamber 1, a right mold body 3 fixedly connected to the right side of the inner side of the injection chamber 1, a demolding auxiliary mechanism 4 movably connected to the bottom of both the injection chamber 1 and the injection molding machine 2, and a demolding buffer mechanism 5 movably connected to the inner side of the injection chamber 1.

[0029] The demolding auxiliary mechanism 4 includes an injection platform 41, a support base plate 42, an adjusting block 43, and an angle adjusting component 44. The injection platform 41 is fixedly connected to the bottom of the injection chamber 1 and the injection molder 2. The support base plate 42 is rotatably connected to the bottom of the injection platform 41. The angle adjusting component 44 is movably connected to the top of the support base plate 42. The adjusting block 43 is movably connected to the inner side of the angle adjusting component 44 and is located at the bottom of the injection platform 41.

[0030] In this embodiment: the angle adjustment component 44 can push the adjustment block 43 to move in the gap between the support base plate 42 and the injection platform 41, thereby adjusting the angle between the injection platform 41 and the support base plate 42, thereby causing the overall injection structure composed of the injection chamber 1, the injection unit 2 and the mold body 3 to be in an inclined state, ensuring that the material adheres to the inner side of the mold body 3 with the demolding structure on the lower side.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the demolding buffer mechanism 5 includes a first electric telescopic platform 51, a stepped buffer block 52, a spring assembly 53, a push rod 54, and an extension block 55.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the first electric telescopic platform 51 is located inside the injection chamber 1, the stepped buffer block 52 is movably connected to the right side of the first electric telescopic platform 51, and the spring assembly 53 is movably connected to the inside of the stepped buffer block 52.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, push rod 54 is fixedly connected to the right side of stepped buffer block 52, and extension block 55 is fixedly connected to the left side of left mold body 3.

[0034] In this embodiment: when the first electric telescopic push rod 54 moves to the rear side of the left mold body 3, the stepped buffer block 52 between the push rod 54 and the first electric telescopic platform 51 will first contact the extension block 55 on the rear side of the left mold body 3. During the advancement, the extension block 55 squeezes the stepped buffer block 52 to shrink it, thus buffering the advancing speed of the push rod 54. The stepped buffer block 52 has a nested stepped telescopic shape and a spring group 53 inside. When compressed, the multiple springs in the spring group 53 store energy to generate a push force to offset the pressure, so that the push rod 54 advances in a stepped manner and buffers when demolding, avoiding damage to the material.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the angle adjustment assembly 44 includes a guide rod 44a, a sliding support block 44b, and an electric lead screw 44c.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the guide rod 44a is fixedly connected to the top of the support base plate 42, the sliding support block 44b is fixedly connected to the left side of the adjusting block 43, the sliding support block 44b is slidably connected to the outside of the guide rod 44a, the electric screw 44c is threadedly connected to the inside of the sliding support block 44b, and the electric screw 44c is movably connected to the top of the support base plate 42.

[0037] In this embodiment: the rotation of the electric lead screw 44c drives the outer sliding support block 44b to slide along the guide rod 44a, causing the rear adjusting block 43 to enter the gap between the support base plate 42 and the injection platform 41. The adjusting block 43 is a triangular-like body with one side inclined. After entering the gap, it moves towards the side where the support base plate 42 and the injection platform 41 are axially connected, squeezing the top injection platform 41 to make it rotate less than 90 degrees. In this way, before injection, the internal structure of the injection molder 2 and the injection chamber 1 can be adjusted to an inclined position, so that the left and right mold bodies 3 are inclined. After the bodies are combined, the left mold body 3 is located below. When the injection molding is completed and the mold is demolded, the left and right mold bodies 3 separate. The outer skin of the soccer ball remains inside the left mold body 3 due to the oblique gravity. It can be easily demolded through its inner demolding structure, avoiding material retention in the right mold body 3 during horizontal injection, reducing manual intervention and improving injection efficiency. By adjusting different angles, it can also be adapted to different models of soccer balls, enhancing the injection effect. In addition, by using the second electric telescopic platform 6 to push the front of the support plate 7, the left mold body 3 and the right mold body 3 can be combined.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, a second electric telescopic platform 6 is fixedly connected to the left side of the inner side of the injection chamber 1, a support plate 7 is fixedly connected to the right side of the second electric telescopic platform 6, a first electric telescopic platform 51 is movably connected to the right side of the support plate 7, and the left mold body 3 is fixedly connected to the right side of the support plate 7.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, a guide ramp 8 is movably connected to the top of the injection molding platform 41. The guide ramp 8 is located inside the injection molding chamber 1, and a discharge port 9 is opened on the front side of the injection molding chamber 1.

[0040] In this embodiment: the second electric telescopic platform 6 pushes the support plate 7, which can drive the left mold body 3 to move to the right and merge with the right mold body 3 to achieve the injection molding requirements. The injection molding of the soccer ball skin is spherical. After it falls off, it can roll along the guide inclined plate 8 and the push rod 54 enters the collection structure set on the outside through the discharge port 9.

[0041] Working principle: During the injection molding of the soccer ball skin, the corresponding mold body 3 needs to be selected and installed in the designated installation position of the injection molding machine 2 according to the different soccer balls being processed. Before merging the left mold body 3 and the right mold body 3 for injection molding, the rotation of the electric screw 44c drives the sliding support block 44b on its outer side to slide along the guide rod 44a. During the sliding process, it can drive the rear adjusting block 43 to gradually enter the gap between the support base plate 42 and the injection platform 41. The adjusting block 43 is a triangular-like body with one inclined surface. After entering the gap, it will move towards the side where the support base plate 42 and the injection platform 41 are axially connected. The top injection platform 41 is squeezed to rotate less than 90 degrees, thereby adjusting the entire injection molding machine 2 and the internal structure of the injection chamber 1 to an inclined state before injection. This ensures that after the left mold body 3 and the right mold body 3 are combined, the left mold body 3 is positioned below. This allows the left mold body 3 to separate from the right mold body 3 when demolding is required after injection. The soccer ball skin can then be placed inside the left mold body 3 by gravity and easily demolded through the demolding structure inside the left mold body 3. This avoids the situation where horizontally injected material remains on the right mold body 3, requiring manual intervention and resulting in poor injection efficiency. Adjusting the angle can accommodate different models of soccer balls and enhance the injection molding effect of the injection molding machine 2. After the left mold body 3 and right mold body 3 on the front side of the support plate 7 are merged by the second electric telescopic platform 6 and the injection molding is completed, the electric screw 44c is used to adjust it to a horizontal state. At the same time as the second electric telescopic platform 6 is extended, the first electric telescopic platform 51 extends forward and drives the push rod 54 to push forward, achieving the demolding effect. During the process of the first electric telescopic push rod 54 moving to the rear of the left mold body 3, the stepped buffer block connected between the push rod 54 and the first electric telescopic platform 51... 52 will first contact the extension block 55 on the rear side of the left mold body 3. During the advancement process, the extension block 55 will squeeze the stepped buffer block 52 to shrink it, thereby achieving the effect of buffering the advancing speed of the push rod 54. Since the stepped shrink block is in the shape of nested stepped extension and retraction, and a spring group 53 is provided on its inner side, when under pressure, the multiple springs on the inner side of the spring group 53 will store energy to generate a push force to achieve the effect of offsetting. This allows the push rod 54 to be pushed in a buffered stepped manner when it is demolded, thereby avoiding damage to the material. In addition, the injection molding of the soccer ball skin is spherical. After it is removed, it can roll along the guide inclined plate 8, and the push rod 54 exit port 9 enters the collection structure set on the outside.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
