[0002] With national economic development and technological advancements, the trend in industrial development is towards automated and intelligent production. Molds, as the foundation of industry, especially need to achieve automated production. Currently, however, manual demolding is still used in the production of epoxy products, which cannot meet the requirements for rapid demolding. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a mold that is easy to demold.

[0004] The technical solution adopted in this embodiment of the utility model is a mold that is easy to demold, including a body, a cavity provided in the body, the body including multiple modules, the modules being provided with recesses, the multiple modules being molded together to form the body, and the recesses on the modules being joined together to form a cavity after the multiple modules are molded together.

[0005] At least one of the modules is equipped with a product ejection mechanism.

[0006] Furthermore, the product ejection mechanism includes a plurality of pin holes formed on the module and connected to the recess. A pin is inserted into the pin hole. One end of the pin near the recess is flush with the end of the pin hole connected to the recess, and the other end of the pin extends out of the pin hole away from the recess. The pin can move along the pin hole and extend into the recess.

[0007] Furthermore, a groove is formed on the wall surface of the recessed part of the module at the position corresponding to the pin hole, and a slider is placed in the groove. One end of the slider extends into the recess and is formed onto the product.

[0008] Furthermore, the product ejection mechanism also includes a drive mechanism, which drives the ejector pin to move along the pin hole and extend into the recess to eject the product.

[0009] Furthermore, the driving mechanism includes a transmission rod and a lever. The lever is disposed corresponding to the ejector pin and is sleeved on the transmission rod. The transmission rod is rotatably mounted on the module. The rotation of the transmission rod drives the lever to push the ejector pin.

[0010] Furthermore, the driving mechanism also includes a limiting block, which has a through hole that cooperates with the transmission rod. The limiting block is sleeved on the transmission rod through the through hole and fixed to the module so that the transmission rod can be rotatably mounted on the module.

[0011] Furthermore, the drive mechanism also includes a power source that drives the transmission rod to rotate.

[0012] Furthermore, the power source includes a telescopic cylinder, which is fixed on the module, and a rack is fixedly connected to the output end of the telescopic cylinder. A gear that meshes with the rack is sleeved on the transmission rod, and the rack meshes with the gear.

[0013] Furthermore, the power source also includes a fixing block, which has a through hole that matches the rack. The fixing block is fixed to the module, and the rack passes through the through hole to keep the rack meshing with the gear.

[0014] Furthermore, the push block is a cam. When the ejector pin is pushed out by the drive, the center of the cam to the farthest point on the outer contour of the cam presses against the ejector pin. When the ejector pin is not pushed out, the base circle portion on the cam presses against the ejector pin.

[0015] Compared with existing technologies, the mold proposed in this technical solution is easy to demold and has a product ejection mechanism. The product ejection mechanism can smoothly eject the epoxy product from the mold, providing a guarantee for the realization of automated production.

[0016] Furthermore, it can achieve automation to replace manual operation, thereby avoiding possible errors during operation, thus ensuring product quality and improving the degree of automation, reliability and production efficiency of epoxy products.

[0026] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0027] See Figures 1 to 4 This utility model provides a mold that is easy to demold, including a body, a cavity inside the body, a plurality of modules, a recess on the module, the plurality of modules being molded together to form the body, and the recesses on the modules being joined together to form the cavity after the plurality of modules are molded together.

[0028] At least one of the modules is equipped with a product ejection mechanism. The mold proposed in this technical solution, which facilitates easy demolding, has a product ejection mechanism that allows epoxy products to be smoothly ejected from the mold, thus ensuring automated production.

[0029] Furthermore, it can achieve automation to replace manual operation, thereby avoiding possible errors during operation, thus ensuring product quality and improving the degree of automation, reliability and production efficiency of epoxy products.

[0030] Specifically, the product ejection mechanism includes several pin holes 2 formed on the module and connected to the recess. Ejector pins 3 are inserted into the pin holes 2. One end of the ejector pin 3 near the recess is flush with the end of the pin hole 2 connecting to the recess, and the other end of the ejector pin 3 extends out of the pin hole 2 away from the recess. The ejector pin 3 can move along the pin holes 2 and extend into the recess. When demolding is required, the ejector pin 3 is pushed along the pin holes 2 and extends into the recess to eject the product, making operation convenient.

[0031] In some embodiments, a groove 4 is formed on the wall surface of the recessed portion of the module at the position corresponding to the pin hole 2. A slider 5 is placed in the groove 4, and one end of the slider 5 extends into the recess and is formed onto the product. By having the slider 5 directly contact the product, the contact area can be increased, preventing the ejector pin 3 from directly hitting the product and damaging it.

[0032] In some embodiments, the product ejection mechanism further includes a drive mechanism for driving 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 lever 7. The lever 7 is positioned corresponding to the ejector pin 3 and is sleeved on the transmission rod 6. The transmission rod 6 is rotatably mounted on the module. The rotation of the transmission rod 6 drives the lever 7, causing the lever 7 to push the ejector pin 3. In the demolding state, the transmission rod 6 in the driving mechanism drives the lever 7 to rotate, and the lever 7 pushes the ejector pin 3 to eject the product.

[0034] In some embodiments, the driving mechanism further includes a limiting block 8, which has a through hole that mates with the transmission rod 6. The limiting block 8 is sleeved on the transmission rod 6 through the through hole and fixed to the module, so that the transmission rod 6 is rotatably mounted on the module. The limiting block 8 rotatably mounts the transmission rod 6 on the module and leaves a gap between the transmission rod 6 and the module for the movement of the toggle block 7.

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

[0036] Specifically, the power source includes a telescopic cylinder 9, which is fixed to the module. A rack 10 is fixedly connected to the output end of the telescopic cylinder 9. A gear 11, which meshes with the rack 10, is sleeved on the transmission rod 6. Through the meshing of the rack 10 and gear 11, the telescopic cylinder 9 synchronously drives the transmission rod 6, allowing the ejector pin 3 to be synchronously driven by the push block 7, thereby smoothly ejecting the product from the mold.

[0037] Furthermore, the power source also includes a fixing block 12, which has a through hole that matches the rack 10. The fixing block 12 is fixed to the module, and the rack 10 passes through the through hole to keep the rack 10 meshing with the gear 11. Installing the rack 10 with the fixing block 12 improves the stability of the rack 10 and gear 11 during power transmission.

[0038] In some embodiments, the push block 7 is a cam. When the ejector pin 3 is driven to be ejected, the center of the cam to the farthest point on the outer contour of the cam 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 and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
