The traditional mold change process often involves complex disassembly and installation steps, which not only increases the difficulty of operation but also extends the production cycle. The cumbersome mold change process directly leads to a reduction in production efficiency. Therefore, it is necessary to design a low-expansion, high-precision composite material molding device to solve the above problems. Utility Model Content

[0022] 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.

[0023] Example 1

[0024] Please refer to Figure 1-5 As shown, this utility model provides a low-expansion, high-precision composite material molding device, including a support member 1. The support member 1 is slidably connected to two sets of connecting seats 2. The opposite sides of the two sets of connecting seats 2 are respectively detachably connected to an upper mold 3 and a lower mold 4. The opposite sides of the upper mold 3 and the lower mold 4 are each rotatably connected to a locking member. The locking member can lock the upper mold 3 and the lower mold 4 by rotation.

[0025] The support component 1 serves as the foundation of the entire device, and its sliding connection includes two sets of connecting seats 2. This sliding connection design allows the connecting seats 2 to move freely on the support component 1, thereby adjusting the relative position between the upper mold 3 and the lower mold 4 to accommodate the molding requirements of composite materials of different sizes and shapes.

[0026] The upper mold 3 and lower mold 4 are connected to two sets of connecting seats 2 via a detachable fitting method. The fitting connection design ensures a tight fit between the mold and the connecting seats without gaps, thereby guaranteeing the stability and precision of the connection and ensuring that the mold will not shift or shake during the molding process. Each of the opposite sides of the upper mold 3 and lower mold 4 is rotatably connected to a set of locking parts. After the mold is installed in place, rotating the locking parts can lock it together with the connecting seats 2, thus achieving a firm fixation of the mold through rotation.

[0027] The detachable interlocking connection and rotary locking mechanism make mold assembly and disassembly simple and quick. Operators can quickly change molds without complicated tools or skills, thereby improving production efficiency. The interlocking connection design ensures a tight fit between the mold and the connecting seat without gaps, thus guaranteeing accuracy and stability during the molding process. This helps reduce dimensional deviations and shape distortions after composite material molding, improving product quality. The rotary locking mechanism of the locking component further enhances the stability of the mold during the molding process. Through rotary locking, the mold is firmly fixed on the connecting seat 2 and will not shift or shake due to vibration or external force, thus ensuring the smooth progress of the molding process.

[0028] Specifically, the locking components include a rotating rod 5, a baffle 6, a first sliding groove 7, and a knob 8. Two sets of rotating rods 5 are rotatably connected to opposite sides of the upper mold 3 and the lower mold 4. A baffle 6 is installed at the other end of each rotating rod 5. Both sets of connecting seats 2 have a first sliding groove 7 corresponding to the baffle 6. A knob 8 is installed on one side of the baffle 6. Both the upper mold 3 and the lower mold 4 are equipped with four sets of demolding components. Each set of baffles 6 locks two sets of demolding components by rotation. The upper mold 3... Each of the lower molds 4 has four sets of second slide grooves 9. Each set of second slide grooves 9 is equipped with a set of demolding components, including springs 10 and limiting rods 11. A set of springs 10 is installed in the inner cavity of each set of second slide grooves 9. The springs 10 are sleeved on the outside of the limiting rods 11. The limiting rods 11 can be locked by the baffles 6. A set of limiting blocks 12 is installed at one end of the limiting rods 11. The limiting blocks 12 can be engaged with the baffles 6. A set of pull rings 13 is installed at the end of the limiting blocks 12 away from the limiting rods 11.

[0029] When the mold needs to be locked, the operator turns knob 8, causing the rotating rod 5 and baffle 6 to rotate together. Baffle 6 first penetrates the first sliding groove 7, and then rotates to offset it, preventing the upper mold 3 and lower mold 4 from disengaging from the connecting seat 2. At the same time, the rotation of baffle 6 allows it to engage with the limiting block 12, locking the limiting rod 11 and preventing it from being pulled by spring 10. The shape and length of the limiting rod 11 are selected and adapted according to requirements to ensure that one end remains flush with the inner cavity of the mold when locked, without affecting the molding of the material.

[0030] When demolding is required, the operator first releases the lock of the baffle 6 on the limiting block 12. At this time, the elastic force of the spring 10 will pull the limiting block 12, causing the limiting rod 11 to move into the mold cavity. The movement of the limiting rod 11 will push the molded material out of the mold, achieving demolding. Pulling the pull ring 13 can move the limiting block 12 to keep it in a position where it can engage with the baffle 6 for locking next time.

[0031] Rotating the knob 8 causes the baffle 6 to rotate and engage with the limiting block 12, which securely locks the limiting rod 11, preventing displacement or shaking of the mold during molding and ensuring molding accuracy and stability. During demolding, simply releasing the baffle 6 from the limiting block 12 allows the spring force of the spring 10 to automatically eject the molded material from the mold, eliminating the need for additional demolding tools or complex operating steps, thus improving demolding efficiency. Both locking and demolding processes are completed through simple rotation and pulling operations, requiring no complex tools or skills, reducing operational difficulty and improving production efficiency.

[0032] Wherein: the opposite ends of the upper mold 3 and the lower mold 4 are each connected to the output end of a set of electric push rods 14. The two sets of electric push rods 14 are respectively connected to the upper and lower ends of the support member 1. The support member 1 includes a support plate 15 and support rods 16. The support plate 15 is provided with two sets. Four sets of support rods 16 are installed between the two sets of support plates 15. The four sets of support rods 16 all penetrate the connecting seat 2, the upper mold 3 and the lower mold 4, and are slidably connected to them.

[0033] The opposite ends of the upper mold 3 and the lower mold 4 are each connected to the output end of a set of electric push rods 14. The two sets of electric push rods 14 are respectively connected to the upper and lower ends of the support member 1. When it is necessary to adjust the position of the mold, the electric push rods 14 extend or retract, push or pull the connecting seat 2, thereby driving the upper mold 3 and the lower mold 4 to adjust their positions.

[0034] Four sets of support rods 16 are installed between the two sets of support plates 15. The support rods 16 are cylindrical structural components that penetrate the connecting seat 2, the upper mold 3, and the lower mold 4, and are slidably connected to them. The design of the support rods 16 not only improves the stability of sliding but also ensures the accuracy and straightness of the mold during movement.

[0035] By extending or retracting the electric push rod 14, the distance and position between the upper mold 3 and the lower mold 4 are precisely controlled to adapt to the molding requirements of composite materials with different thicknesses and shapes. During the molding process, the support member 1 provides stable support to ensure the stability and accuracy of the mold under high pressure and high temperature. The design of the support member 1 provides a stable support foundation. The rectangular structure of the support plate 15 and the cylindrical structure of the support rod 16 together ensure the stability and accuracy of the mold during movement and molding.

[0036] Working principle: When the mold needs to be locked, the operator turns knob 8, causing the rotating rod 5 and baffle 6 to rotate together. Baffle 6 first penetrates the first sliding groove 7, and then rotates to offset it, so that the upper mold 3 and lower mold 4 will not disengage from the connecting seat 2. At the same time, the rotation of baffle 6 allows it to engage with the limiting block 12, completing the locking of the limiting rod 11, preventing it from being pulled by spring 10. The shape and length of the limiting rod 11 are selected according to requirements to ensure that one end remains flush with the inner cavity of the mold when locked, without affecting the molding of the material. When demolding is required, the operator first releases the locking of the limiting block 12 by baffle 6. At this time, the elastic force of the spring 10 will pull the limiting block 12, causing the limiting rod 11 to move into the mold cavity. The movement of the limiting rod 11 will push the molded material out of the mold, realizing demolding. Pulling the pull ring 13 can drive the limiting block 12 to move, keeping it in a position that can be engaged with the baffle 6 for locking next time. The opposite ends of the upper mold 3 and the lower mold 4 are each connected to the output end of a set of electric push rods 14. The two sets of electric push rods 14 are respectively connected to the upper and lower ends of the support 1. When it is necessary to adjust the mold position, the electric push rods 14 extend or retract, push or pull the connecting seat 2, thereby driving the upper mold 3 and the lower mold 4 to adjust their positions.
