[0030] Composite material molds are often used during the production process of composite materials products. Due to the limitation of product shape, some products cannot be demoulded, so the mold needs to be made into a detachable split mold. During the demoulding process of the product, the junction between the mold surface and the parting surface of the split mold is easily damaged, resulting in unevenness of the product after a period of use, which requires product repair, resulting in waste of materials and labor, and increased costs.

[0031] See also Figure 1 to Figure 4In view of this, the present application provides a composite material split mold, including a first mold 100, a second mold 200, a connector 300, a first reinforcing strip 410 and a second reinforcing strip 420. The first mold 100 and the second mold 200 cooperate to form a mold for making a product. The first mold 100 is provided with a first connecting portion 110, and the second mold 200 is provided with a second connecting portion 210. The first connecting portion 110 and the second connecting portion 210 are connected by the connector 300 to achieve relative fixation of the first mold 100 and the second mold 200 to make the product. A first embedding area is provided at the mold surface of the first connecting portion 110, and the first reinforcing strip 410 is fixed in the first embedding area, and the surface of the first reinforcing strip 410 is flush with the mold surface of the first mold 100. By providing the first reinforcing strip 410 in the first embedding area, the strength of the mold surface of the first connecting portion 110 is improved, thereby preventing the mold surface of the first connecting portion 110 from being damaged during demolding, especially when demolding is difficult and requires demolding with tools, reducing the damage to the mold surface. Preferably, the first reinforcing strip 410 is a metal strip, such as an iron metal strip, etc., to improve the strength of the mold surface of the first connecting part 110 and reduce wear. A second embedding area is provided on the mold surface of the second connecting part 210, and the second reinforcing strip 420 is fixed in the second embedding area, and the surface of the second reinforcing strip 420 is flush with the mold surface of the second mold 200. By arranging the second reinforcing strip 420 in the second embedding area, the strength of the mold surface of the second connecting part 210 is improved, thereby preventing the mold surface of the second connecting part 210 from being damaged during demolding, especially when demolding is difficult and requires demolding with tools, the damage to the mold surface is reduced. Preferably, the second reinforcing strip 420 is a metal strip, such as an iron metal strip, etc., to improve the strength of the mold surface of the second connecting part 210 and reduce wear. By arranging the first reinforcing strip 410 and the second reinforcing strip 420 on the mold surfaces of the first connecting part 110 and the second connecting part 210, respectively, the strength here is effectively improved, wear is reduced, and demolding is convenient.

[0032] See also Figure 2In an exemplary embodiment of the composite material split mold, a first stopper 411 is provided on the first reinforcing strip 410 in the direction away from the mold surface of the first mold 100, and the first stopper 411 is fixed to the first reinforcing strip 410 through a first connecting rod 412. The first stopper 411 extends into the first mold 100, thereby increasing the connection strength between the first reinforcing strip 410 and the first mold 100, and preventing the first reinforcing strip 410 from falling off. Further, along the axial direction of the first connecting rod 412, the projection of the first stopper 411 exceeds the projection of the abutment area between the first connecting rod 412 and the first stopper 411. In other words, a step is formed at the connection between the first stopper 411 and the first connecting rod 412, and the first stopper 411 is inserted into the first mold 100, further increasing the connection strength between the first stopper 411 and the first mold 100, and limiting the first reinforcing strip 410 from leaving the first mold 100.

[0033] In an exemplary embodiment of a split mold for a composite material, a projection of the first limiting portion 411 along the axial direction of the first connecting rod 412 exceeds a projection of the first connecting rod 412 along the axial direction of the first connecting rod 412. Preferably, the first limiting portion 411 is cylindrical or rectangular, the connecting rod is cylindrical, and the first limiting portion 411 is embedded in the first mold 100. The first mold 100 part on the peripheral side of the connecting column restricts the first limiting portion 411 from detaching from the first mold 100, thereby restricting the first reinforcement strip 410 from detaching from the first mold 100 and improving the service life.

[0034] In an exemplary embodiment of a composite material split mold, a first reinforcing rib is provided on the first connecting rod 412, and the first reinforcing rib is not parallel to the axial direction of the first connecting rod 412. Preferably, the first reinforcing rib is perpendicular to the axial direction of the first connecting rod 412. By providing the first reinforcing rib, on the one hand, the contact area with the first mold 100 can be increased, and on the other hand, the first mold 100 will be filled between the first reinforcing ribs, thereby further increasing the connection strength between the first limit portion 411 and the first mold 100.

[0035] See also Figure 2 In an exemplary embodiment of the composite material split mold, the second reinforcing strip 420 is provided with a second stopper 421 in the direction away from the mold surface of the second mold 200. The second stopper 421 is fixed to the second reinforcing strip 420 through a second connecting rod 422. Along the axial direction of the second connecting rod 422, the projection of the second stopper 421 exceeds the projection of the abutment area between the second connecting rod 422 and the second stopper 421. Similarly, by providing the second stopper 421 and the second connecting rod 422, the connection strength between the second reinforcing strip 420 and the second mold 200 is enhanced, preventing the second reinforcing strip 420 from falling off during demoulding, thereby increasing the service life.

[0036] In an exemplary embodiment of a composite material split mold, a screw is fixed to the first reinforcing strip 410 in the direction away from the mold surface of the first mold 100, and the screw rod of the screw is fixed to the first reinforcing strip 410; a screw is also fixed to the second reinforcing strip 420 in the direction away from the mold surface of the second mold 200, and the screw rod of the screw is fixed to the second reinforcing strip 420. The fixing method of the screw to the first reinforcing strip 410 and the screw to the second reinforcing strip 420 can be threaded connection, welding, bonding, etc., or other existing fixing methods, which can achieve the fixing of the screw to the first reinforcing strip 410 and the fixing of the screw to the second reinforcing strip 420. The screw has the advantages of convenient material selection and low cost. The first reinforcing strip 410 and the second reinforcing strip 420 can be processed from metal sheets to form metal strips, so that the composite material split mold has the effect of low manufacturing cost and convenient material selection. Preferably, the first reinforcing strip 410 and the second reinforcing strip 420 are respectively provided with mounting holes, and the screws are respectively welded to the first reinforcing strip 410 and the second reinforcing strip 420 after being inserted into the mounting holes. By providing the mounting holes, the contact surface between the screw and the first reinforcement bar 410 and the second reinforcement bar 420 is increased, thereby improving the connection strength.

[0037] In an exemplary embodiment of a composite material split mold, the first reinforcing strip 410 is disposed at the junction of the mold surface and the parting surface of the first mold 100. In other words, the first reinforcing strip 410 is disposed at the edge of the mold surface of the first mold 100. When demolding, tools may be occasionally needed to knock or pry the mold to separate the product from the mold. The first reinforcing strip 410 is disposed at the edge of the mold surface of the first mold 100 to ensure the strength of the knocking or prying point and reduce damage to the first mold 100. Similarly, the second reinforcing strip 420 is disposed at the junction of the mold surface and the parting surface of the second mold 200 to reduce damage to the second mold 200.

[0038] In an exemplary embodiment of the composite material split mold, through holes are provided on the first connection part 110 and the second connection part 210, and the connecting member 300 passes through the through holes to fix the first connection part 110 and the second connection part 210. Preferably, the connecting member 300 is a bolt, and the first connection part 110 and the second connection part 210 are relatively fixed by the bolt, which is convenient for disassembly and assembly, thereby improving the convenience of use of the split mold.

[0039] Exemplarily, a reinforcement frame is provided on the side of the first mold 100 and the second mold 200 facing away from the mold surface, and the reinforcement frame improves the strength of the first mold 100 and the second mold 200 and facilitates the removal and placement of the first mold 100 and the second mold 200.

[0040] See also Figure 1 and Figure 3The present application also provides a male mold 500 for making a split mold, including a main body and a reinforcing strip 400. The main body is used to make the mold surface of the split mold, that is, the surface of the male mold 500 abuts against the mold surface of the split mold, so as to be used to make the split mold. The reinforcing strip 400 is arranged on the main body, and the reinforcing strip 400 corresponds to the parting surface of the split mold. In the production of the split mold, the reinforcing strip 400 is directly embedded in the mold surface at the parting surface of the split mold, so that the reinforcing strip 400 is fixed to the mold surface of the split mold. Preferably, the reinforcing strip 400 is bonded to the main body, so that after the split mold is produced, the reinforcing strip 400 is separated from the main body with the split mold, and the reinforcing strip 400 forms a part of the split mold.

[0041] Furthermore, the split mold includes a first mold 100 and a second mold 200 , and the reinforcing strip 400 includes a first reinforcing strip 410 and a second reinforcing strip 420 , and the first reinforcing strip 410 and the second reinforcing strip 420 are respectively arranged on the first mold 100 and the second mold 200 .

[0042] In an exemplary embodiment of a male mold for making a split mold, a screw is fixed on the side of the reinforcing strip 400 facing away from the main body. The screw and the reinforcing strip 400 can be fixed by threaded connection, welding, etc., preferably welding. The screw is embedded in the split mold to enhance the connection strength between the reinforcing strip 400 and the split mold, prevent the reinforcing strip 400 from detaching from the split mold, and increase the service life.

[0043] Exemplarily, when making a split mold by making a male mold of the split mold, first fix the reinforcing strip 400 on the main body corresponding to the parting surface of the split mold. The reinforcing strip 400 is preferably a metal strip, and the material is easy to obtain and convenient to process and use. Preferably, a screw or bolt is fixed on the side of the reinforcing strip 400 away from the main body, and the screw or bolt is fixed to the reinforcing strip 400 by threaded connection or welding. After the reinforcing strip 400 is fixed on the main body, a composite material, such as glass fiber, is pasted on the main body. The composite material passes through the screws or bolts, which increases the bonding force between the reinforcing strip 400 and the split mold. After the composite material is pasted, wait for the split mold to solidify. After the split mold is solidified, remove the split mold from the male mold 500, and the different parts of the split mold are relatively fixed by connecting parts 300, such as bolts, so as to obtain a completed composite material split mold.

[0044] The utility model composite material split mold has the beneficial effects of improving the strength of the mold surface corresponding to the parting surface, reducing the wear of the split mold, reducing the cost of repairing the mold and the product, reducing the cost, and improving the product quality. Therefore, the utility model effectively overcomes some practical problems in the prior art and has a high utilization value and use significance. The above embodiments are only illustrative of the principle and efficacy of the utility model, and are not used to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model.
