[0003] In the field of golf ball mold manufacturing, traditional mold designs often suffer from problems such as low cooling efficiency, difficulty in demolding, and unstable ejection. These problems are particularly prominent when producing high-quality, high-precision golf balls, thus necessitating improvements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-efficiency and high-volume golf ball mold with 16 cavity per ejection. By optimizing the mold structure, particularly the configuration of the air blowing system, ejection system, and cooling system, efficient, precise, and stable production of the golf ball mold is achieved. The cooling system improves cooling efficiency and uniformity by increasing the number of cooling pipes; the air blowing system achieves non-destructive demolding through precise control of air blowing position and force; and the ejection system, through redundant design, ensures long-term ejection stability and reliability.

[0005] To achieve the above objectives, this utility model provides a high-efficiency and high-volume golf ball mold with 16 holes per stroke, comprising a first mold core and a second mold core. Both the first mold core and the second mold core are provided with N groups of mold holes, and each group of mold holes includes at least M mold holes for fixing the mold core, where N and M are both positive integers, and M>N≥2.

[0006] The first mold core is equipped with an air blowing system and an ejection system, and both the first mold core and the second mold core are equipped with a cooling system;

[0007] The cooling system is provided with A cooling pipes, and any one of the cooling pipes is located between two of the mold cavities, where A is a positive integer and A>N;

[0008] The air blowing system is equipped with B air sleeves, where B is a positive integer and B = M;

[0009] The top feeding system is equipped with C ejector pins, where C is a positive integer and C>M.

[0010] Preferably, both the first mold core and the second mold core include a first template and a second template;

[0011] The first template has a cooling channel inside, and the cooling pipe passes through the cooling channel;

[0012] The second template has an air blowing channel inside, and the air sleeve is connected to the air blowing channel.

[0013] The first mold core has a first template and a second template both having a through-hole ejector channel, and the ejector pin is inserted into the ejector channel;

[0014] The cavity is set in the first template.

[0015] Preferably, the second template has a fixed cavity that communicates with the mold cavity, and the air sleeve is fixed in the fixed cavity.

[0016] Preferably, the air jacket includes an air guide component, which is provided with a plurality of air jet holes facing the mold cavity.

[0017] Preferably, the outer periphery of the mold cavity is provided with an injection groove, and the injection groove is provided with a guide port communicating with the mold cavity;

[0018] One end of the ejector pin is provided with an abutment portion, which is located above the injection groove.

[0019] Preferably, the abutting part includes a pressing block and a connecting block, the connecting block is fixed to the ejector pin, and the pressing block is fixed to the end of the connecting block away from the ejector pin.

[0025] The beneficial effects of this invention are as follows: By incorporating cooling systems in both the first and second mold cores, and configuring A cooling pipes (where A > N), this invention ensures sufficient cooling pipes around each mold cavity group. This design not only improves cooling efficiency but also guarantees cooling uniformity, thereby effectively avoiding molding quality problems caused by temperature differences.

[0026] The air blowing system is precisely matched to the number of mold cavities, with B air sleeves corresponding to M mold cavities, and B = M.

[0036] The present invention is described in detail below with reference to the accompanying drawings.

[0037] See Figures 1 to 6 As shown, this utility model discloses a high-efficiency and high-volume golf ball mold with 16 holes per die, comprising a first die core 1 and a second die core 2. Both the first die core 1 and the second die core 2 are provided with N die core groups 3. Each die core group 3 includes at least M die cores 31 for fixing the die core, where N and M are both positive integers, and M>N≥2. In this embodiment, N is 2, i.e., 2 die core groups 3, and M is 8, i.e., each die core group 3 is provided with 8 die cores 31.

[0038] The first mold core 1 is equipped with an air blowing system 4 and an ejector system 5, and both the first mold core 1 and the second mold core 2 are equipped with a cooling system 6;

[0039] The cooling system 6 is provided with A cooling pipes 61, and any cooling pipe is located between two mold cavities 31, where A is a positive integer and A>N. In this embodiment, A is used as an example of 3 pipes, with 1 main pipe connecting 2 branch pipes.

[0040] The air blowing system 4 is equipped with B air jackets 41, where B is a positive integer and B = M.

[0041] The ejector system 5 is provided with C ejector pins 51, where C is a positive integer and C>M. In this embodiment, C is a multiple of M, so that each cavity 31 is provided with 4 ejector pins 51, which disperses the ejection force and reduces the wear of the ejector pins 51.

[0042] By incorporating cooling systems 6 in both the first mold core 1 and the second mold core 2, and configuring A cooling pipes 61, where A > N, sufficient cooling pipes are ensured around each mold cavity group 3. This design not only improves cooling efficiency but also guarantees cooling uniformity, thereby effectively avoiding molding quality problems caused by temperature differences.

[0043] The air blowing system 4 is precisely matched with the number of mold cavities 31, that is, B air sleeves 41 correspond to M mold cavities 31, and B = M. This one-to-one air blowing control method can more accurately control the blowing force and position, ensuring that the golf ball is not damaged during demolding, while improving demolding efficiency.

[0044] The ejector system 5 is equipped with C ejector pins 51, where C > M. This redundant design not only ensures the stability of the ejector but also extends the service life of the ejector pins 51 by dispersing the ejection force. Even if some ejector pins 51 wear out due to long-term use, the remaining ejector pins 51 can still ensure the smooth demolding of the golf ball, guaranteeing the continuity of production and the integrity of the product.

[0045] By optimizing the mold structure, especially the configuration of the air blowing system 4, the ejection system 5, and the cooling system 6, efficient, precise, and stable production of golf ball molds was achieved. The cooling system improved cooling efficiency and uniformity by increasing the number of cooling pipes; the air blowing system 4 achieved non-destructive demolding by precisely controlling the air blowing position and force; and the ejection system 5 ensured long-term ejection stability and reliability through redundant design.

[0046] See Figure 1 and Figure 3 As shown, in this embodiment, both the first mold core 1 and the second mold core 2 include a first template 101 and a second template 102.

[0047] The first template 101 has a cooling channel inside, and the cooling pipe 61 passes through the cooling channel.

[0048] The cooling channels formed inside the mold by the cooling pipe 61 utilize the circulating flow of a cooling medium, such as water or oil, to remove the heat generated during the production process, thereby achieving rapid cooling. This helps to shorten the mold's cooling time and improve production efficiency.

[0049] The second mold 102 has an internal air blowing channel, and the air sleeve 41 is connected to the air blowing channel. Gas is blown into the air blowing channel inside the mold using the air sleeve 41, creating a certain air pressure difference. This reduces the friction between the molded golf ball and the inner wall of the mold, making it easier to eject the ball from the mold. This demolding method not only reduces the risk of mold damage but also improves demolding efficiency.

[0050] The first template 101 and the second template 102 of the first mold core 1 are both provided with a material ejector channel, and the ejector pin 51 is inserted into the material ejector channel.

[0051] The ejector pin 51 moves up and down within the ejector channel to eject the molded golf ball from the mold. The stability and reliability of the ejector mechanism are crucial for ensuring product quality and improving production efficiency. This design, through the ejector channel that runs through the first mold plate 101 and the second mold plate 102, ensures that the ejector pin 51 can eject the golf ball stably and evenly.

[0052] The cavity 31 is set on the first template 101, so that the mold core is fixed on the first template 101.

[0053] See Figure 3 As shown, in this embodiment, the second template 102 of the first mold core 1 is provided with a fixed cavity 103 that communicates with the mold cavity 31, and the air sleeve 41 is fixed in the fixed cavity 103.

[0054] By rationally designing the shape and size of the fixing cavity 103 and selecting appropriate fixing methods, such as bolt connection or welding, the air sleeve 41 is firmly fixed inside the second template 102. This ensures that the mold remains stable when subjected to various forces and vibrations.

[0055] See Figure 2 As shown, the air jacket 41 in this embodiment includes an air guide 42, which is provided with a plurality of air jet holes 43, which face the mold cavity 31.

[0056] The blown gas is evenly distributed within the mold cavity 31 through multiple air jets 43 on the air guide 42, reducing the friction between the golf ball and the inner wall of the mold, thus making demolding easier. This design utilizes the diffusion and distribution characteristics of gas in a closed space to ensure the consistency and stability of the demolding effect.

[0057] By adjusting the parameters of the air jets 43, such as their number, size, and distribution, precise control of the flow rate and pressure of the blown gas can be achieved, thereby regulating the magnitude and direction of the demolding force. This design utilizes the principles of fluid mechanics, achieving regulation of the demolding force by altering the gas flow state.

[0058] See Figure 4 As shown, the outer periphery of the mold cavity 31 in this embodiment is provided with a sprue groove 32, and the sprue groove 32 is provided with a guide port 33 that communicates with the mold cavity 31.

[0059] One end of the ejector pin 51 is provided with an abutment part 511, which is located above the injection groove 32.

[0060] The injection groove 32 and the guide port 33 connected to it on the outer periphery of the mold cavity 31 allow the raw material to be injected into the mold cavity more quickly and evenly. This design optimizes the injection process, reduces the flow resistance and time of the raw material in the mold, and thus improves the injection efficiency.

[0061] The design of the injection groove 32 and the guide port 33 helps ensure that the raw material can fully fill the mold cavity 31, reducing material waste and voids within the mold. This helps improve material utilization and reduce production costs.

[0062] The abutment portion 511 at one end of the ejector pin 51 is located above the injection groove 32. This design allows the ejector pin to apply force more evenly to the sprue of the golf ball during the ejection process, avoiding product defects caused by the ejector pin 51 directly acting on the golf ball. At the same time, the design of the abutment portion 511 also helps to reduce friction between the ejector pin and the mold, extending the service life of the mold.

[0063] The design of the injection groove 32, the guide port 33, and the abutment part 511 simplifies the mold operation process, making it easier for operators to perform injection, ejection, and other operations. This helps to improve production efficiency and reduce operational difficulty.

[0064] See Figure 6 As shown, the abutting part 511 in this embodiment includes a pressing block 512 and a connecting block 513. The connecting block 513 is fixed to the ejector pin 51, and the pressing block 512 is fixed to the end of the connecting block 513 away from the ejector pin 51.

[0065] The abutment part 511 is divided into a pressing block 512 and a connecting block 513, which allows the ejector pin 51 to more precisely control the force transmission during the ejection process. The pressing block 512 directly contacts the sprue of the golf ball, which can apply the ejection force more evenly and avoid product defects caused by uneven force.

[0066] See Figure 5 As shown, the top material system 5 in this embodiment is provided with D top pressure modules 52, where D is a positive integer and D = N.

[0067] Since the number D of the ejector modules 52 in the ejector system 5 is equal to the number N of the cavity groups 3, each cavity group 3 has a corresponding ejector module. This design ensures that after the golf ball is formed, the products in all cavity groups 3 can be ejected simultaneously, significantly improving ejection efficiency.

[0068] Each mold cavity group 3 has an independent ejection module for the ejection operation, avoiding product defects caused by uneven ejection force. This design ensures that each golf ball receives uniform force during ejection, thereby improving the overall quality of the product.

[0069] Because the ejector module 52 corresponds one-to-one with the cavity group 3, the force distribution during ejection is more uniform, reducing wear and deformation of the mold caused by uneven force. This design helps extend the service life of the mold and reduce production costs.

[0070] When producing golf balls of different sizes or materials, simply replace the corresponding cavity group 3 and top pressure module. This design improves the flexibility and adaptability of the mold, meeting the needs of diversified production.

[0071] See Figure 5 As shown, in this embodiment, both the first mold core 1 and the second mold core 2 are provided with a base plate 104, two limiting plates 105 and multiple connecting pieces 106. The two limiting plates 105 are respectively provided on both sides of the base plate 104 through multiple connecting pieces 106.

[0072] A stable frame is formed by the fixed connection of the base plate 104, two limiting plates 105, and multiple connecting parts 106. This design significantly improves the overall structural stability of the mold and ensures its normal operation under harsh environments such as high pressure and high temperature.

[0073] D ejector modules 52 are arranged side-by-side between two limiting plates 105. This design ensures the positioning accuracy of the ejection system 5 during the ejection process. Each ejector module 52 can accurately correspond to the corresponding mold cavity group 3, avoiding ejection failure or product defects caused by positioning deviation.

[0074] See Figure 5 and Figure 6 As shown, each top pressing module 52 in this embodiment includes a top pressing plate 521, a top pressing strip 522, and a limiting abutment 523. The top pressing strip 522 is disposed on the top of the top pressing plate 521, and the limiting abutment 523 is disposed on the bottom of the top pressing plate 521.

[0075] The other end of the ejector pin 51 is provided with a top contact part 514, which is fixed to the limiting plate 523.

[0076] By designing a top pressure module 52 that includes a top pressure plate 521, a top pressure strip 522, and a limiting stop plate 523, the entire structure is more stable and can ensure that it will not loosen or shift during the top pressure process.

[0077] The top pressure strip 522 is set on the top of the top pressure plate 521, which can achieve precise top pressure on the target object, improving processing accuracy and efficiency.

[0078] The other end of the ejector pin 51 is fixed to the limiting plate 523 via the top connection part 514. This connection method is simple and reliable, and can ensure the stability and accuracy of the ejector pin 51 during the pressing process.

[0079] The overall structural design makes top-pressure operation more convenient, reduces the labor intensity of operators, and improves work efficiency.

[0080] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
