Description

Technical Field

[0001] This utility model relates to the technical field of badminton racket processing equipment, specifically a carbon fiber badminton racket mold that is easy to mold. Background Technology

[0002] As the sporting goods industry upgrades towards lightweight and high-performance, carbon fiber materials, due to their high strength and light weight, have become the core material for high-end badminton rackets. The precision and molding efficiency of carbon fiber badminton racket molds directly determine the racket's appearance, mechanical properties, and production capacity.

[0003] Existing carbon fiber badminton racket molds mostly adopt a split upper and lower mold structure, which has obvious technical defects in the mold closing process. Traditional molds rely on manual alignment of the parting surface. Due to the lack of reliable positioning and guiding devices, the positional deviation of the upper and lower molds is difficult to control accurately, which often leads to low mold closing efficiency. Each mold closing requires repeated adjustments, which takes a long time and significantly reduces the production efficiency of carbon fiber badminton rackets. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a carbon fiber badminton racket mold that is easy to mold.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber badminton racket mold that facilitates mold assembly, comprising a top mold and a bottom mold, the top mold being located above the bottom mold, and both the upper end of the bottom mold and the lower end of the top mold having mold cavities. The top mold has multiple grooves on both sides, with slots inside the grooves. The bottom mold has multiple positioning blocks symmetrically arranged on both sides, with an inclined plate at the top of each positioning block. The positioning blocks vertically penetrate the grooves, and the positioning blocks have cavities inside. A second spring is provided inside the cavity, with one end of the second spring fixed inside the cavity and the other end having a locking block that mates with the slots. The locking block has a right-angled trapezoidal structure. Two pull rods are symmetrically arranged on both sides of the bottom mold, with both ends of the pull rods penetrating the second springs and connecting to the locking blocks. The top mold has multiple positioning holes at its edge, and the bottom mold has multiple vertical columns that penetrate the positioning holes at its edge.

[0006] To make the top mold easier to handle, the present invention includes an improvement where a handle is fixedly provided at the upper end of the top mold.

[0007] To provide a buffering effect for the top mold during mold closing, the present invention includes the following improvements: multiple slots are provided at the edge of the bottom mold, a first spring is provided in the slot, the bottom end of the first spring is fixed to the bottom of the slot, a buffer block is provided at the top end of the first spring, and a column is fixed to the upper end of the buffer block. Both the column and the buffer block are cylindrical structures, and the diameter of the buffer block is larger than the diameter of the column.

[0008] Furthermore, the improvements of this utility model include that the lower surface of the top mold is in close contact with the upper surface of the bottom mold, the positioning block is in close contact with the inner wall of the groove, and the column is in close contact with the positioning hole.

[0009] To facilitate mold closing, the improvements of this utility model include: the bottom end of the positioning hole is an outwardly expanding flared structure; the positioning block and the inclined plate are an integrated structure; and the column and the buffer block are an integrated structure.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a carbon fiber badminton racket mold that is easy to mold, and has the following beneficial effects: The positioning block and groove cooperate, and the column and positioning hole (including the flared mouth) guide, combined with the inclined plate at the top of the positioning block, to form a multi-positioning and guiding mechanism. The top mold and bottom mold can be accurately aligned without repeated manual adjustments, which greatly improves the mold closing efficiency and thus improves the production efficiency of carbon fiber badminton rackets.

[0011] The locking block (right-angled trapezoidal structure) and the locking slot automatically engage under the action of the second spring, ensuring that the top mold and bottom mold are firmly attached after mold closing, avoiding positional displacement during the molding process, ensuring the mold cavity closing accuracy, and reducing the product defect rate.

[0013] 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.

[0014] Please see Figures 1-5 This utility model proposes a carbon fiber badminton racket mold that is easy to close, including a top mold 1 and a bottom mold 2. The top mold 1 is located above the bottom mold 2. The upper end of the bottom mold 2 and the lower end of the top mold 1 are provided with mold cavities 3. The top mold 1 has multiple grooves 4 on both sides, and the grooves 4 have slots 9 inside. The bottom mold 2 has multiple positioning blocks 10 symmetrically arranged on both sides. The top of the positioning block 10 has an inclined plate. The positioning block 10 vertically penetrates the groove 4. The positioning block 10 has a cavity 11 inside. The cavity 11 has a second spring 13. One end of the second spring 13 is fixed inside the cavity 11, and the other end has a locking block 12 that cooperates with the slot 9. The locking block 12 has a right-angled trapezoidal structure. The bottom mold 2 has two pull rods 14 symmetrically arranged on both sides. The two ends of the pull rods 14 penetrate the second spring 13 and connect to the locking block 12. The top mold 1 has multiple positioning holes 5 at its edge, and the bottom mold 2 has multiple vertical columns 6 that penetrate the positioning holes 5 at its edge.

[0015] The lower surface of the top mold 1 is in close contact with the upper surface of the bottom mold 2, the positioning block 10 is in close contact with the inner wall of the groove 4, and the column 6 is in close contact with the positioning hole 5.

[0016] When closing the mold, the carbon fiber badminton racket material is first placed in the mold cavity 3 of the bottom mold 2.

[0017] A handle 15 is fixedly installed at the upper end of the top mold 1.

[0018] Lift the top mold 1 by using the handle 15 at the top of the top mold 1, so that the positioning blocks 10 on both sides of the bottom mold 2 are aligned with the grooves 4 on both sides of the top mold 1, and the inclined plate at the top of the positioning block 10 guides it to slide into the groove 4.

[0019] The bottom of the positioning hole 5 is an outwardly expanding flared structure, the positioning block 10 and the inclined plate are an integrated structure, and the column 6 and the buffer block 7 are an integrated structure.

[0020] Meanwhile, the column 6 on the edge of the bottom mold 2 passes through the positioning hole 5 on the edge of the top mold 1, and the flared structure at the bottom of the positioning hole 5 assists in the precise insertion of the column 6.

[0021] The bottom mold 2 has multiple slots 8 at its edge. A first spring is installed in the slot 8. The bottom end of the first spring is fixed to the bottom of the slot 8. A buffer block 7 is installed at the top end of the first spring. A column 6 is fixed to the top end of the buffer block 7. Both the column 6 and the buffer block 7 are cylindrical structures, and the diameter of the buffer block 7 is larger than the diameter of the column 6.

[0022] During the descent of the top mold 1, its lower surface gradually approaches the upper surface of the bottom mold 2. The buffer block 7 at the top of the column 6 first contacts the positioning hole 5. The pressure of the top mold 1 causes the buffer block 7 to compress the first spring in the empty groove 8, forming a buffer and avoiding direct rigid collision between the top mold 1 and the bottom mold 2.

[0023] At this time, the locking block 12 in the inner cavity 11 of the positioning block 10 contracts due to the pressure from the inner wall of the top mold 1, compressing the second spring 13 in the cavity 11.

[0024] Continue pressing down the top mold 1 until the lower surface of the top mold 1 is tightly fitted with the upper surface of the bottom mold 2, the buffer block 7 is fully inserted into the empty groove 8, and the first spring is in a compressed state.

[0025] At this time, the second spring 13 resets, pushing the locking block 12 out of the cavity 11 and engaging with the locking groove 9 inside the groove 4 of the top mold 1, thus achieving a stable fixation between the top mold 1 and the bottom mold 2, and the mold closing is completed.

[0026] During demolding, pull rods 14 on both sides of the bottom mold 2 are pulled. Pull rods 14 cause the locking block 12 to compress the second spring 13 and disengage from the locking groove 9. Subsequently, the first spring in the empty groove 8 returns to its original position, pushing the buffer block 7 upward and causing the top mold 1 to rise, creating a gap between the top mold 1 and the bottom mold 2. Finally, the molded carbon fiber badminton racket can be removed by lifting the top mold 1 with the handle 15.

[0027] The buffer block 7 and the first spring form a buffer structure, which can absorb the impact force of the top mold 1 when the mold is closed, reduce the rigid collision between the top mold 1 and the bottom mold 2, protect the mold parting surface, and extend the service life. The pull rod 14 design makes it easier for the locking block 12 to disengage from the locking slot 9, and, together with the lifting force on the top mold 1 when the first spring returns to its original position, makes the demolding operation less strenuous. The handle 15 facilitates the removal and placement of the top mold 1, improving the overall ease of operation.

[0028] The coordinated action of each component not only solves the problems of difficult mold alignment and low efficiency in traditional molds, but also ensures mold life and product quality through buffering and stabilizing structures, making it suitable for large-scale production needs.

[0029] Selection criteria for the first spring (the installation method of the first spring and the second spring 13 is the same, so the installation method of the first spring does not need to be described in detail here): The first spring is installed in the empty groove 8 of the bottom mold 2, and the upper end is connected to the buffer block 7. Its core function is to buffer the downward impact force of the top mold 1 when the mold is closed, so as to avoid the rigid collision between the top mold 1 and the bottom mold 2. When demolding, the buffer block 7 is pushed to lift the top mold 1 by the reset spring force to form the mold opening gap.

[0030] The selection must meet the following requirements: Elasticity characteristics: It needs to have a medium load-bearing capacity, so that it can be smoothly compressed when the top mold 1 is pressed down (absorbing the impact force), and can provide enough elasticity to lift the top mold 1 when demolding. The elasticity needs to match the weight of the top mold 1 and the impact force when the mold is closed. Stroke adaptation: The compression stroke is consistent with the distance from when the buffer block 7 fully enters the empty slot 8, ensuring that the spring is in a stable compressed state when the mold is closed; Materials and Structure: Carbon spring steel (such as 65Mn) is selected, which has good impact resistance and fatigue strength. A cylindrical helical compression spring structure is adopted, with a moderate wire diameter (to fit the space of the slot 8). Both ends are ground flat to ensure that the buffer block 7 is subjected to uniform force.

[0031] Selection criteria for the second spring 13: The second spring 13 is located in the cavity 11 of the positioning block 10 and is connected to the locking block 12. Its main function is to be squeezed and contracted by the locking block 12 when the mold is closed (allowing the top mold 1 to descend), and automatically reset after the mold is closed, pushing the locking block 12 to lock into the slot 9 of the top mold 1 to achieve locking; when demolding, it is pulled and compressed by the pull rod 14 (unlocking).

[0032] The selection must meet the following requirements: Elasticity characteristics: The elasticity should be moderate, so that it can be easily compressed by the locking block 12 when the top mold 1 descends (to avoid obstructing mold closing), and can reliably push the locking block 12 to lock the slot 9 after the mold is closed (to ensure a stable lock). Space adaptation: Since it is assembled in the cavity 11 of the positioning block 10, a small cylindrical helical compression spring with a thinner wire diameter and a compact number of turns is required to adapt to the limited installation space. Materials and Durability: High-strength spring steel (such as 50CrVA) is selected, which has excellent elastic recovery and fatigue resistance, adapts to frequent expansion and contraction conditions (mold closing-mold release cycle), and ensures stable elasticity after long-term use.
