Description

Technical Field

[0001] The utility model relates to the technical field of molds, and specifically, to a mold with an automatic demolding function. Background Art

[0002] During the process of manufacturing plastic products with plastic molds, it is necessary to take out the manufactured plastic products from the molds. However, the manufactured plastic products are still sticky, and generally, the plastic products will adhere to the molds. The existing solution is to manually push the plastic products out of the molds with a push rod. During the pushing process, the ejecting end of the push rod will contact the bottom of the plastic products. When the push rod pushes the plastic products out of the molds, it may cause deformation of the just-injected plastic products, and in severe cases, it will directly pierce the plastic products. When the plastic products are deformed or pierced, it will directly lead to the inability to be put into subsequent use.

[0003] Regarding molds with an automatic demolding function, there are many existing technologies. For example:

[0004] Chinese Patent Publication No. CN115709244B discloses a mold with an automatic demolding function, including a machine tool and a workpiece. The machine tool includes a punch and a die. A driving component is arranged inside the machine tool, and the driving component is used to control the engagement of the punch and the die. One end of the punch is connected with a stamping oil cavity. A pushing component is arranged between the punch and the die. A separating component is arranged inside the punch. The separating component includes an oil guiding component and a separating component. A separating component is arranged inside the die. The present invention realizes hierarchical separation of the punch inside the formed workpiece through the separating component, reduces the mold wrapping force of the workpiece during the stamping process, and realizes automatic demolding in cooperation with stamping oil and a baffle. The separating component provides the function of the die, and during the discharging period, the die and the formed workpiece are quickly separated. The pushing component realizes the feeding and discharging of the workpiece, and avoids repeated use of lubrication.

[0005] However, as described above, when the existing technology is used, the formed products are hierarchically separated inside the workpiece by using the driving component and the pushing component, and its structure is relatively complex, increasing the equipment cost.

[0006] In view of this, the utility model provides a new mold with an automatic demolding function. Summary of the Utility Model

[0008] To achieve the above object, the present utility model provides a mold with an automatic demoulding function, including a base. Four lower hydraulic rods are provided on the upper surface of the base. The fixed ends of the lower hydraulic rods are fixedly connected to the base. A lower mold is provided at the top of the lower hydraulic rods. The telescopic ends of the lower hydraulic rods are fixedly connected to the lower mold.

[0021] Currently, in the existing technology during use, a driving component and a pushing component are utilized to hierarchically separate the formed product inside the workpiece, and its structure is relatively complex, increasing the equipment cost.

[0022] Please refer to Figures 1 - 3 As shown, this embodiment provides a mold with an automatic demolding function, including a base 10. Four lower hydraulic rods 20 are provided on the upper surface of the base 10, whose main purpose is to provide pressure. The fixed end of the lower hydraulic rod 20 is fixedly connected to the base 10. A lower mold 21 is provided at the top of the lower hydraulic rod 20, whose main purpose is to be responsible for the forming of the lower part of the product. The telescopic end of the lower hydraulic rod 20 is fixedly connected to the lower mold 21. There is a flange at the bottom of the lower mold 21, whose main purpose is to prevent overflow. An upper mold 22 is provided above the lower mold 21, whose main purpose is to be responsible for the forming of the upper part of the product. Four upper hydraulic rods 23 are provided at the top of the upper mold 22, whose main purpose is to provide pressure. The telescopic end of the upper hydraulic rod 23 is fixedly connected to the upper mold 22. There is a flange at the top of the upper mold 22, whose main purpose is to prevent overflow. A controller 24 is provided at the bottom of the upper hydraulic rod 23, whose main function is to control the operation of the overall equipment. The fixed end of the upper hydraulic rod 23 is fixedly connected to the controller 24. A middle mold 14 is provided between the lower mold 21 and the upper mold 22, whose main function is to be responsible for the forming of the middle part of the product. A notch is opened in the middle of the middle mold 14. The lower surface of the middle mold 14 can contact the flange of the lower mold 21, and the upper surface of the middle mold 14 can contact the flange of the upper mold 22, whose main purpose is to prevent the lower mold 21 and the upper mold 22 from being squeezed too much, resulting in unqualified products.

[0023] First, an extension plate 11 is provided on one side of the base 10. A main shaft 13 is fixedly connected to the upper surface of the extension plate 11, whose main purpose is to support the operation of the equipment. The main shaft 13 is fixedly connected to the middle mold 14. A connecting rod 15 is provided on the side of the top of the main shaft 13. One side of the connecting rod 15 is fixedly connected to the controller 24.

[0024] Furthermore, a cooling pipe 16 is opened in the middle of the middle mold 14, whose main purpose is to cool the middle mold 14, enabling the formed product to be quickly cooled. The pipeline of the cooling pipe 16 forms a circulating water path around the inside of the middle mold 14, whose main purpose is to increase the contact area, enabling the product to be cooled faster and increasing the efficiency.

[0025] Still further, four feet 12 are provided at the bottom of the base 10, whose main purpose is to ensure the balance of the equipment.

[0026] When the mold with an automatic demolding function in this embodiment is specifically used:

[0027] The operation controller 24 is activated to open the lower hydraulic rod 20, causing the lower die 21 to reach the appropriate position. The product material is poured into the middle die 14, and the product material is received by the lower die 21. Then, the upper hydraulic rod 23 is activated to lower the upper die 22 to the appropriate position. Subsequently, the lower hydraulic rod 20 and the upper hydraulic rod 23 are simultaneously activated to extrude and form the product material. After an appropriate time, the lower hydraulic rod 20 and the upper hydraulic rod 23 are simultaneously activated to withdraw the lower die 21 and the upper die 22 from the middle die 14. At the same time, cold water is discharged into the cooling pipe 16, and the cooling water reduces the temperature of the middle die 14 and simultaneously transfers the temperature to the formed product, causing the product to be cooled and demolded, thus completing the forming production of the product.
