[0028] At least one of the modules is equipped with a product ejection mechanism. The technical solution provides a mold that is easy to demould and has a product ejection mechanism, through which the epoxy product can be smoothly ejected from the mold, providing a guarantee for realizing automated production.

[0029] And it can realize automation to replace manual operation, thus avoiding errors that may occur during operation, thereby ensuring product quality and improving the degree of automation, reliability and production efficiency of epoxy products.

[0030] Specifically, the product ejection mechanism includes a plurality of pin holes 2 opened on the module and connected to the recess, wherein an ejector pin 3 is inserted into the pin hole 2, wherein one end of the ejector pin 3 close to the recess is flush with the end of the pin hole 2 connected to the recess, and the other end of the ejector pin 3 extends out of the end of the pin hole 2 away from the recess, and the ejector pin 3 can move along the pin hole 2 and extend into the recess. When demolding is required, the ejector pin 3 is pushed along the pin hole 2 and extends into the recess to eject the product, which is convenient to operate.

[0031] In some embodiments, a groove 4 is provided on the wall surface of the recessed portion of the module at a position corresponding to the pin hole 2, and a slider 5 is placed in the groove 4. One end of the slider 5 extends into the recessed portion and is formed on the product. The slider 5 directly contacts the product, which can expand the contact area and prevent the ejector pin 3 from directly hitting the product and damaging the product.

[0032] In some embodiments, the product ejection mechanism further includes a driving mechanism, which is used to drive the ejector pin 3 to move along the pin hole 2 and extend into the recess to eject the product.

[0033] Specifically, the driving mechanism includes a transmission rod 6 and a shift block 7. The shift block 7 is arranged corresponding to the ejector pin 3, and the shift block 7 is sleeved on the transmission rod 6. The transmission rod 6 is rotatably mounted on the module. The transmission rod 6 rotates to drive the shift block 7, so that the shift block 7 pushes the ejector pin 3. In the demolding state, the transmission rod 6 in the driving mechanism drives the shift block 7 to rotate, and the shift block 7 pushes the ejector pin 3 to eject the product.

[0034] In some embodiments, the driving mechanism further includes a stopper block 8, on which a through hole is provided to cooperate with the transmission rod 6, and the stopper block 8 is sleeved on the transmission rod 6 through the through hole, and the stopper block 8 is fixed to the module so that the transmission rod 6 can be rotatably mounted on the module. The transmission rod 6 is rotatably mounted on the module through the stopper block 8, and a spacing space is reserved between the transmission rod 6 and the module, and the spacing space is used for the movement of the shifting block 7.

[0035] In some embodiments, the driving mechanism further includes a power source, and the power source drives the transmission rod 6 to rotate.

[0036] Specifically, the power source includes a telescopic cylinder 9, which is fixed on the module, and the output end of the telescopic cylinder 9 is fixedly connected to a rack 10, and the transmission rod 6 is sleeved with a gear 11 that cooperates with the rack 10, and the rack 10 is meshed with the gear 11. Through the cooperation between the rack 10 and the gear 11, the telescopic cylinder 9 can synchronously drive the transmission rod 6, so that the ejector pin 3 can be synchronously driven by the shifting block 7, so that the product can be smoothly ejected from the mold.

[0037] The power source further includes a fixing block 12, on which a through hole matching the rack 10 is formed, the fixing block 12 is fixed to the module, and the rack 10 passes through the through hole so that the rack 10 is kept meshed with the gear 11. The rack 10 is installed by the fixing block 12, thereby improving the stability of the rack 10 and the gear 11 during the power transmission process.

[0038] In some embodiments, the shift block 7 is a cam. When the ejector pin 3 is driven to be ejected, the farthest point from the center of the cam to the cam contour presses against the ejector pin 3. When the ejector pin 3 is not ejected, the base circle portion on the cam presses against the ejector pin 3.

[0039] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
