Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically to a grip injection molding device. Background Technology

[0002] With the global popularity and development of golf, players have increasingly stringent performance requirements for golf equipment. As the only point of contact between the player and the club, the golf grip's comfort, grip resistance, and durability directly affect swing stability and shot performance, becoming a key component determining the quality of the equipment. The grip leather, as the core component of the grip, is closely related to its molding quality and performance. However, traditional manufacturing processes are gradually showing limitations in precision control, material utilization, and production efficiency, making it difficult to meet the ever-increasing performance demands of modern golf grip leather.

[0003] For example, Chinese Patent Publication No. CN214562453U discloses an injection molding device, which relates to the field of injection molding equipment technology. The purpose of this utility model is to provide an injection molding device that facilitates the separation of profile molds, has a high degree of automation, and improves the overall injection molding efficiency of the equipment. The key technical point is that the injection molding device includes a base, a connecting rod fixedly installed on the top of the base, a fixing rod fixedly installed on the top of the connecting rod, and four connecting rods and four fixing rods. An upper mold is movably installed between the four connecting rods, a material cylinder is fixedly installed on the top of the upper mold, and a rotary motor is fixedly installed on the top of the material cylinder. The technical effect is that by setting the cavity above and the core below, it is easy to separate the profile from the cavity. At the same time, the fixed cylinder is energized and drives the lower mold to move down, so that the core passes through the through hole and enters the inner cavity of the base. The profile is blocked by the top wall of the base and remains at the top of the base, thus achieving separation from the core.

[0004] However, the aforementioned injection molding device can only perform single-batch injection molding in the mold during the injection process. This requires the mold to open and close and the material to be unloaded after each batch of production is completed. The accumulated waiting time will significantly increase the production cycle and make it difficult to meet the needs of large-scale production. Summary of the Invention

[0005] The purpose of this utility model is to provide a grip injection molding device to solve the problems mentioned in the background art. Because the mold can only be used for single-batch injection molding, the injection molding device needs to repeat the process of mold opening and closing and manual material handling for each batch of production, resulting in long equipment idle time, poor production continuity, and a significant increase in the overall production cycle. This makes it unsuitable for large-scale mass production, and the frequent mechanical movements exacerbate mold wear and increase labor costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A grip injection molding device includes an operating table. A grip injection molding machine is fixedly mounted on the upper surface of the operating table. One end of the injection port of the grip injection molding machine is connected to a sealing cylinder through an injection port. The injection port is located at one end of the outer surface of the sealing cylinder. The sealing cylinder is supported on the upper surface of the operating table by a collar fitted on its outer surface. A mold column is slidably and sealed inside the sealing cylinder. Multiple sets of embedded square grooves are equidistantly formed on the outer surface of the mold column. Multiple sets of handle sleeve grooves are equidistantly formed in each set of embedded square grooves. A molding mechanism can be inserted into the handle sleeve groove, and the distance between the molding mechanism and the handle sleeve groove forms a handle sleeve-shaped cavity.

[0007] In the aforementioned grip injection molding device, the multiple grip sleeve slots in each set of the embedded square grooves are connected by flow grooves, which are formed on the upper surface of the embedded square grooves.

[0008] In the aforementioned grip injection molding device, a loop heat absorption pipe is fixedly installed inside the mold column. The inlet pipe and outlet pipe of the loop heat absorption pipe both extend out from inside the mold column, and the inlet pipe is connected to the inlet of an external water pump, and the outlet pipe is connected to the outlet of an external water pump.

[0009] In the aforementioned grip injection molding device, the molding mechanism includes an inner plate with an arc-shaped surface. Multiple molding columns are fixedly assembled at equal intervals at the other end of the inner plate. When the inner plate is inserted into the inner square groove by the pins at its four corners, it can simultaneously drive the molding columns to be sealed and inserted into the grip sleeve groove, and a grip sleeve-shaped cavity is formed between the molding columns and the grip sleeve groove.

[0010] In the aforementioned grip injection molding device, the inner plate inserted into the inner square groove has a surface flush with the outer surface of the mold column, and the inner plate can slide into the sealing cylinder together with the mold column; a T-shaped groove is provided at one end of the outer surface of the inner plate, and when the inner plate is inserted into the inner square groove, the T-shaped groove is connected to the flow groove.

[0011] In the aforementioned grip injection molding device, a motor is fixedly mounted at one end of the sealing cylinder, the output shaft of the motor rotates through the sealing cylinder, and a T-shaped column is fixedly mounted at the end of the output shaft. The T-shaped column is slidably mounted inside the mold column. The motor can drive the mold column to rotate inside the sealing cylinder through the T-shaped column, and the rotating mold column can sequentially drive the T-shaped groove on the inner plate to connect with the injection port.

[0012] In the aforementioned grip injection molding device, two sets of electric push rods are fixedly mounted on one end of the sealing cylinder. The piston rods of both sets of electric push rods slide through into the sealing cylinder, and the ends of the piston rods are fixedly connected to one end of the rotating ring. The rotating ring is embedded and rotatably mounted on one end of the outer surface of the mold column. The electric push rods can push the mold column out of the sealing cylinder through the extension action of the piston rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The molding mechanism and mold pillars work together to form multiple cavities. The flow channel and T-slot ensure uniform distribution of raw materials, enabling continuous and orderly injection molding of multiple cavities, significantly increasing output per unit time and meeting the needs of large-scale production. The motor and electric push rod drive the mold pillar to rotate and enter and exit the sealed cylinder, reducing manual intervention and lowering the complexity and labor intensity of operation. The loop heat absorption pipe accelerates the cooling and solidification of raw materials, ensuring stable product quality. Furthermore, one set of mold pillars can complete multiple batches of production, reducing the frequency of mold replacement, reducing wear and maintenance costs of parts, and avoiding the impact of differences between different molds, thus improving product consistency and achieving a balance between efficiency, cost, and quality.

[0016] 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.

[0017] like Figures 1-3As shown, this embodiment provides a grip injection molding device, including: an operating table 1, a grip injection molding machine 101 fixedly installed on the upper surface of the operating table 1, one end of the injection port of the grip injection molding machine 101 being connected to a sealing cylinder 102 through an injection port 108, and the injection port 108 being opened at one end of the outer surface of the sealing cylinder 102, the sealing cylinder 102 being supported on the upper surface of the operating table 1 by a collar fitted on the outer surface, a mold column 103 being slidably sealed inside the sealing cylinder 102, the outer surface of the mold column 103 being provided with multiple sets of embedded square grooves 105 at equal intervals, and each set of embedded square grooves 105 being provided with multiple sets of handle sleeve grooves 106 at equal intervals, the handle sleeve grooves 106 being able to insert a molding mechanism 2 and the spacing between them forming a handle sleeve-shaped cavity.

[0018] In each set of embedded square grooves 105, multiple sets of handle grooves 106 are connected by flow grooves 107, which are located on the upper surface of the embedded square grooves 105. A loop heat absorption pipe 104 is fixedly installed inside the mold column 103, and the inlet and outlet pipes of the loop heat absorption pipe 104 extend from the mold column 103 and are connected to the inlet and outlet of an external water pump.

[0019] Through the design of the grip injection molding machine 101, sealing cylinder 102, mold column 103, loop heat absorption pipe 104, embedded square groove 105, grip sleeve groove 106, flow groove 107, injection port 108, and molding mechanism 2, in use, the molding mechanism 2 is first inserted into the grip sleeve groove 106 of the mold column 103. The gap between the molding mechanism 2 and the grip sleeve groove 106 forms multiple cavities matching the shape of the golf grip leather. Since the multiple grip sleeve grooves 106 in each set of embedded square grooves 105 are connected by the flow groove 107, this establishes a channel for the subsequent flow and distribution of raw materials. Then, the mold column 103 with the molding mechanism 2 installed is slid into the sealing cylinder 102, so that it is in contact with the sealing... The cylinder 102 forms a sliding seal, providing a sealed environment for the injection molding process to prevent material leakage. Simultaneously, the inlet and outlet pipes of the heat absorption pipe 104 within the mold column 103 are connected to the inlet and outlet of an external water pump to ensure the cooling system functions properly. After entering the injection molding stage, the grip injection molding machine 101 can be started. The grip injection molding machine 101 delivers the heated and molten plastic material through its injection port to the injection port 108. Since the injection port 108 is connected to the sealed cylinder 102, the material enters the sealed cylinder 102 through the injection port 108. Under pressure, the material flows along the flow groove 107 on the surface of the embedded square groove 105 on the mold column 103. Through the connecting action of the flow channel 107, the raw material is evenly distributed into the individual grip grooves 106 cavities within each set of embedded square grooves 105 until all cavities are filled. Then, by repeatedly starting the molding mechanism 2, multiple rows of grip grooves 106 are sequentially connected to the injection port 108 for injection molding. During the injection molding process, a water pump can be started simultaneously to drive coolant through the inlet pipe of the loop heat absorption pipe 104 into the loop heat absorption pipe 104 within the mold column 103. The coolant circulates within the loop heat absorption pipe 104, exchanging heat with the molten raw material in the mold column 103 and cavities, absorbing the heat from the raw material, causing it to cool down rapidly and solidify, forming the golf grip leather. After the heat is absorbed, the coolant is discharged through the outlet pipe and cooled, achieving a continuous cooling effect and ensuring that the grip leather can be stably shaped. Once the grip leather is completely cured, the molding mechanism 2 can be activated to push the mold column 103 out of the sealing cylinder 102, releasing the seal. Then, the workers can remove the molding mechanism 2 and take out the molded grip leather from the grip groove 106 for demolding. In this process, the molding mechanism 2 drives multiple rows of grip grooves 106 to be connected to the injection port 108 in sequence for injection molding, realizing continuous production of multiple cavities. This avoids the problem of frequent waiting in traditional single-batch production, greatly increases the output per unit time, and can better meet the needs of large-scale production.

[0020] like Figure 4As shown, the molding mechanism 2 includes an inner plate 205. The surface of the inner plate 205 is arc-shaped, and multiple molding columns 206 are fixedly installed at equal intervals at the other end. During the process of inserting the inner plate 205 into the inner square groove 105 through the four corner pins, the molding columns 206 are also driven to be sealed and inserted into the handle sleeve groove 106, thereby forming a handle sleeve-shaped cavity between the molding columns 206 and the handle sleeve groove 106. The surface of the inner plate 205 inserted into the inner square groove 105 is flush with the outer surface of the molding column 103, allowing it to slide into the sealing cylinder 102 along with the molding column 103. A T-shaped groove 207 is opened at one end of the outer surface of the inner plate 205, and the T-shaped groove 207 is connected to the flow groove 107 through the insertion of the inner square groove 105.

[0021] A motor 201 is fixedly installed at one end of the sealing cylinder 102. The output shaft of the motor 201 passes through the sealing cylinder 102 and a T-shaped column 202 is fixedly installed at its end. The T-shaped column 202 is slidably installed inside the mold column 103, so that the motor 201 can drive the mold column 103 to rotate inside the sealing cylinder 102 through the T-shaped column 202. The rotating mold column 103 can then sequentially drive the T-shaped groove 207 on the inner plate 205 to connect with the injection port 108. Two sets of electric push rods 203 are fixedly installed at one end of the sealing cylinder 102. The piston rods of the two sets of electric push rods 203 slide through the sealing cylinder 102 and are fixedly connected to one end of the rotating ring 204. The rotating ring 204 is embedded and rotatably installed on one end of the outer surface of the mold column 103, so that the electric push rods 203 can push the mold column 103 out of the sealing cylinder 102 through the extension of the piston rod.

[0022] Through the design of the motor 201, T-shaped column 202, electric push rod 203, rotating ring 204, inner plate 205, molding column 206, and T-slot 207, when the grip sleeve is injection molded, the inner plate 205 is inserted into the inner square slot 105 through the four corner pins. During this process, the inner plate 205 will drive multiple molding columns 206 to be sealed and inserted into the grip sleeve slot 106, so that a grip sleeve-shaped cavity is formed between the molding column 206 and the grip sleeve slot 106. At the same time, the surface of the inserted inner plate 205 is flush with the outer surface of the molding column 103, and its outer surface is flush with the outer surface of the mold column 103. The T-shaped groove 207 at one end of the surface is connected to the flow channel 107 to prepare for the flow of raw materials. Then, the electric push rod 203 can be activated to pull the rotating ring 204 into the sealing cylinder 102 via the piston rod. Since the sealing cylinder 102 is rotatably mounted on the outer surface of the mold column 103, the rotating ring 204 can also pull the mold column 103 into the sealing cylinder 102 for sealing. After the mold column 103 slides into the sealing cylinder 102, the motor 201 can be activated to drive the T-shaped column 202 to rotate. Since the T-shaped column 202 is slidably mounted on the mold column 103... This allows the mold column 103 to rotate within the sealing cylinder 102 and the rotating ring 204. During rotation, the mold column 103 sequentially connects the T-slot 207 on the inner insert 205 with the injection port 108. At this time, the molten material delivered by the grip injection molding machine 101 can enter each grip-shaped cavity through the injection port 108, the T-slot 207, and the flow channel 107, achieving orderly injection of multiple cavities. After injection molding is completed and cooled and solidified, the two sets of electric push rods 203 can be restarted to push the rotating ring 204 and drive the mold column. 103 is pushed out from the sealing cylinder 102, allowing the staff to remove the inner plate 205 and pull out the grip sleeve formed by the cooling of the outer surface of the molding column 206 from the grip sleeve groove 106, thus completing one injection molding cycle. By using a set of mold columns 103, multiple batches of grip sleeves can be injection molded, which greatly increases the total production per unit time, better meets the needs of large-scale production, reduces the wear and tear of parts caused by frequent disassembly and assembly of modules, extends the service life of modules and related equipment, and reduces the cost of maintenance and replacement of parts.

[0023] Based on the above technical solution, the working steps of this solution are summarized as follows: When injection molding the grip sleeve, the inner plate 205 can be inserted into the inner square groove 105 through the four corner pins. During this process, the inner plate 205 will drive multiple molding pillars 206 to be sealed and inserted into the grip sleeve groove 106, so that a grip sleeve-shaped cavity is formed between the molding pillars 206 and the grip sleeve groove 106. At the same time, the surface of the inserted inner plate 205 is flush with the outer surface of the mold pillar 103, and the T-shaped groove 207 at one end of its outer surface is connected to the flow groove 107. Then, the electric push rod 203 can be activated to pull the rotating ring 204 into the sealing cylinder 102 via the piston rod. Since the sealing cylinder 102 is rotatably mounted on the outer surface of the mold column 103, the rotating ring 204 can also pull the mold column 103 into the sealing cylinder 102 for sealing. After the mold column 103 slides into the sealing cylinder 102, the motor 201 can be activated to drive the T-shaped column 202 to rotate. Since the T-shaped column 202 is slidably mounted inside the mold column 103, it can drive the mold column 103 to rotate within the sealing cylinder 102 and the rotating ring 204. As the ring 204 rotates, the mold column 103, during its rotation, sequentially connects the T-slot 207 on the inner insert 205 with the injection port 108. At this time, the molten material conveyed by the grip injection molding machine 101 can enter each grip-shaped cavity through the injection port 108, the T-slot 207, and the flow channel 107, achieving orderly injection of multiple cavities. During the injection process, a water pump can be started simultaneously to drive coolant through the inlet pipe of the loop heat absorber 104 into the loop heat absorber 104 inside the mold column 103. The material circulates within the loop heat absorption pipe 104, exchanging heat with the mold column 103 and the molten material in the cavity. It absorbs the heat from the material, causing it to cool down and solidify rapidly, forming the golf grip skin. After cooling and solidification, the two sets of electric push rods 203 can be activated again to push the rotating ring 204, which in turn pushes the mold column 103 out of the sealed cylinder 102. This allows the workers to remove the inner insert 205, which in turn pulls the grip sleeve, which has cooled and solidified on the outer surface of the molding column 206, out of the grip sleeve groove 106, thus completing one injection molding cycle.

[0024] In summary, by using a set of mold pillars 103, multiple batches of grip sleeves can be injection molded, which greatly increases the total production volume per unit time, better meets the needs of large-scale production, reduces the wear and tear of parts caused by frequent disassembly and assembly of modules, extends the service life of modules and related equipment, and reduces the cost of maintenance and replacement of parts.
