Description

Technical Field

[0001] The utility model relates to the technical field of composite material production, in particular to a composite material production mould. Background Art

[0002] Currently, when packaging heavy items (such as automobile steering shafts), they are usually placed on composite materials such as foam plastics. This allows the composite materials to support and cushion the heavy items, preventing collisions and damage during transportation. However, the composite materials produced by existing molds are weak. After placing heavy items on the composite materials for a period of time, the composite materials are prone to breakage and deformation, resulting in the inability to provide effective support and protection for the heavy items. This leads to collisions and deformation of the heavy items, and the composite materials are often scrapped, resulting in waste. Utility Model Content

[0003] The utility model provides a composite material production mold, which can solve the problem of low strength of composite materials produced by existing molds.

[0004] The present application provides the following technical solution: a composite material production mold, comprising an upper mold and a lower mold, wherein support blocks are symmetrically provided at both ends of the upper mold, and limiting mechanisms are symmetrically provided on opposite sides of the two support blocks, wherein the limiting mechanisms include limiting blocks and elastic fasteners, and the upper mold and the lower mold cooperate to form a cavity, and grooves are provided at both ends of the cavity to cooperate with the support blocks.

[0005] Beneficial Effects: Two symmetrically arranged support blocks are used to install an embedded support frame, thereby providing an embedded support frame in the middle of the composite material being produced, effectively improving the strength of the composite material. The limiting mechanism provided on the support block, comprising both a limit block and an elastic fastener, ensures that the embedded support frame is positioned in the middle of the cavity formed by the upper and lower molds, preventing the embedded support frame from being exposed outside the composite material and improving molding accuracy. The elastic fastener enables rapid assembly and disassembly of the embedded support frame, improving production efficiency. Furthermore, when the upper and lower molds are closed, the support block cooperates with the grooves in the lower mold to ensure accurate alignment between the upper and lower molds, reducing mold adjustment time and improving production efficiency.

[0006] Furthermore, it also includes an upper template and a lower template, wherein the upper template is provided with a plurality of upper molds, and the lower template is provided with a plurality of lower molds.

[0007] Beneficial effects: It can improve production efficiency, reduce costs, ensure product quality consistency, improve production flexibility, reduce maintenance costs, and extend mold life.

[0008] Furthermore, the limiting mechanism includes two limiting blocks symmetrically arranged on both sides of the supporting block, and limiting installation grooves are provided on opposite sides of the two limiting blocks.

[0009] Beneficial effect: The limiting installation groove is used to install the embedded support frame and limit the embedded support frame so that a certain gap is left between the embedded support frame and the upper mold to ensure that the embedded support frame is located in the middle of the composite material.

[0010] Furthermore, the lower mold is provided with a supporting column.

[0011] Beneficial effect: The support column is used to provide support for the embedded support frame, and cooperates with the limiting mechanism of the upper mold to ensure that the embedded support frame is located in the middle of the cavity, thereby ensuring that the embedded support frame is located in the middle of the composite material.

[0012] Furthermore, the elastic fastener of the limiting mechanism adopts a ball screw, and the ball screw is detachably mounted on the support block.

[0013] Beneficial Effects: Ball-end screws, located on opposite sides of the two support blocks, are used to position and secure the embedded support frame. They also enable quick assembly and disassembly of the embedded support frame. After long-term use, when the ball-end screws become worn, they can be quickly replaced, improving maintenance efficiency and reducing costs.

[0014] Furthermore, the upper mold is provided with a gun hole.

[0015] Beneficial effect: Injecting raw materials through the gun hole can speed up the filling speed of the mold and improve production efficiency.

[0016] Furthermore, the upper die is provided with a push rod.

[0017] Beneficial effects: Demolding is performed through the ejector pin, which improves production efficiency, reduces the risk of composite material damage, and improves the quality of composite materials.

[0018] Furthermore, the lower mold is provided with a molding groove, and the upper mold covers the molding groove, so that a cavity is formed between the upper mold and the lower mold.

[0019] Beneficial effects: It can effectively improve the molding accuracy and production efficiency of composite materials and reduce production costs.

[0020] Furthermore, the upper die can be inserted into the molding groove of the lower die.

[0021] Beneficial effect: It can ensure the precise alignment between the upper mold and the lower mold, which is conducive to the precise molding of composite products.

[0022] Furthermore, the upper mold and the lower mold are both provided with a plurality of ventilation holes.

[0023] Beneficial effects: The vent holes can effectively discharge the gas generated when the mold is closed, reduce bubbles in the composite product, and help improve the strength and appearance quality of the composite material. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1

[0033] like Figures 1 to 6As shown, a composite material production mold includes an upper template 1 and a lower template 2. The upper template 1 is provided with multiple upper molds 3 in parallel, and the lower template 2 is provided with multiple lower molds 4 in parallel. Each upper mold 3 corresponds to each lower mold 4. The upper molds 3 and lower molds 4 are fixed to the upper template 1 and lower template 2 respectively by bolts. Support blocks 5 extending toward the lower mold 4 are symmetrically provided at both ends of the upper mold 3. The two support blocks 5 are symmetrically provided with limiting mechanisms on opposite sides. The limiting mechanisms include an elastic fastener 501 arranged in the middle of the support block 5 and two limiting blocks 502 symmetrically arranged on both sides of the support block 5. The two limiting blocks 502 are provided with limiting installation grooves 503 on opposite sides. The limiting installation grooves 503 are used to install the embedded support frame 9 and limit the embedded support frame 9, so that a certain gap is left between the embedded support frame 9 and the upper mold 3. The elastic fastener 501 is a ball screw, which is detachably mounted on the support block 5. The ball-end screw comprises a housing, a spring, and a steel ball. The steel ball is retractably mounted within the housing via the spring. The housing's outer wall is provided with external threads, which the ball-end screw utilizes to threadedly engage with threaded holes in the support blocks 5. The steel balls of the ball-end screw are located on opposite sides of the two support blocks 5, serving to position the embedded support frame 9 and secure it to the upper mold. Positioning grooves are provided at each end of the embedded support frame 9, which engage with the steel ball. The lower mold 4 is provided with a molding groove 401. The upper mold 3 overlies the molding groove 401, forming a mold cavity 6 between the upper and lower molds 3 and 4. The mold cavity 6 is provided with grooves 402 at each end, which engage with the support blocks 5. The grooves 402 are located at either end of the lower mold 4. Two lance holes 301 are distributed along the length of the upper mold 3, one near each end of the upper mold 3, for injecting raw material into the mold cavity 6. Three ejector pins 302 are distributed along the length of the upper mold 3 for ejecting the molded product. Two support columns 403 are symmetrically provided at the bottom of the forming groove 401 of the lower mold 4, and the support columns 403 are used to provide support for the embedded support frame 9. A plurality of air holes 7 are provided on both the upper mold 3 and the lower mold 4.

[0034] The processing method is as follows: The embedded support frame 9 can be made of high-strength materials such as wooden strips. Insert the two ends of the wooden strip between the support blocks 5 at both ends of the upper mold 3, so that the wooden strip is installed in the limiting installation groove 503 of the limiting block 502, and use the steel ball of the ball screw to position and clamp the wooden strip, close the upper mold 3 and the lower mold 4, so that the support block 5 of the upper mold 3 is inserted into the groove 402 of the lower mold 4, and the wooden strip is inserted into the molding groove 401 of the lower mold 4, and supported on the support column 403 at the bottom of the molding groove 401, ensuring that the wooden strip is located in the middle position of the cavity 6, and there is a certain gap between the wooden strip and the groove wall of the molding groove 401 to ensure that the foaming material passes through. The foaming material is injected into the mold cavity 6 through the material gun hole 301 of the upper mold 3, and the mold is opened after foaming molding. The molded composite material 8 is ejected by the ejector rod 302 of the upper mold 3, and the wooden strip is located in the middle position of the composite material 8. The cross section of the composite material 8 is as shown Figure 6 shown.

[0035] Example 2

[0036] This embodiment differs from the first embodiment in that the shape of the upper mold 3 corresponds to the groove profile of the molding groove 401 of the lower mold 4. When the molds are closed, the upper mold 3 can be inserted into the molding groove 401 of the lower mold 4. The upper mold plate 1 and the lower mold plate 2 are aligned to form a correspondingly shaped cavity 6 between the upper and lower molds 3 and 4. The shape of cavity 6 can be modified to meet the needs of the specific product. Specifically, wave-shaped grooves are formed on both sides of the upper mold 3, and the groove wall of the molding groove 401 of the lower mold 4 is provided with a wave-shaped groove opposite to the upper mold 3. The wave-shaped grooves are formed on both sides of the molded composite material 8, facilitating the placement of the vehicle steering shaft.
