Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, and in particular to a mold frame that facilitates demolding. Background Technology

[0002] A mold frame is a device used to support molds, and mold processing is one of the most common processing methods for metal parts. Using molds, metal parts can be quickly manufactured into specific shapes and structures, thereby improving production efficiency. A mold frame facilitates demolding, allowing for the rapid removal of the molded product from the mold. This enables more production cycles to be completed per unit time, thus improving overall production efficiency. Difficult demolding may require operators to use excessive force or employ improper operating methods to remove the product, increasing the risk of operator injury. A mold frame that facilitates demolding makes the demolding process easier and safer, reducing safety hazards for operators and ensuring their personal safety.

[0003] Traditional molds require hydraulic cylinders to open the mold after the workpiece is formed, and then ejection cylinders to lift the workpiece and separate it from the lower mold for easy removal. This process involves many steps and is inefficient. Furthermore, traditional molds only have the function of demolding the lower mold. If the workpiece gets stuck in the upper mold, the operator has to push the workpiece to separate it from the upper mold, which may result in poor workpiece forming quality.

[0004] Therefore, those skilled in the art have provided a mold frame that facilitates demolding to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mold frame that facilitates demolding, thereby effectively improving production efficiency and increasing the ease of demolding the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mold frame for easy demolding includes a lower mold, wherein a first demolding mechanism is fixedly connected to both sides of the top of the lower mold, and a second demolding mechanism is fixedly provided at the bottom of the two first demolding mechanisms;

[0008] The first demolding mechanism includes a sliding rod and an inclined block. A slot is provided on one side of the surface of the sliding rod. A connecting rod is fixedly connected to the surface of the inclined block. Guide rails are slidably connected to both sides of the bottom end of the connecting rod. The second demolding mechanism includes a second connecting plate. Two demolding rods are fixedly provided at the bottom end of the second connecting plate. Demolding pieces are fixedly provided at the top ends of the two demolding rods.

[0009] Furthermore, a support column is fixedly connected around the bottom of the lower mold, and a mold base plate is fixedly installed at the bottom of the support column.

[0010] Furthermore, a lower mold cavity is formed in the middle of the top of the lower mold, and two second grooves are formed at the bottom of the lower mold cavity, with connecting grooves formed at the bottom of the two second grooves.

[0011] Furthermore, a telescopic rod is fixedly connected around the top of the lower mold, and an upper mold is fixedly connected to the top of the multiple telescopic rods.

[0012] Furthermore, first connecting plates are fixedly provided on both sides of the top of the mold base plate, and a sliding groove is provided on one side of the surface of the two first connecting plates.

[0013] Furthermore, a stamping block is fixedly connected to the middle of the bottom end of the upper mold, and first grooves are provided on both sides of the bottom end of the upper mold.

[0014] Furthermore, a fixing plate is fixedly installed at one end of each of the two guide rails, and a spring is fixedly installed on one side of the surface of the fixing plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a mold frame that facilitates demolding. By setting a first demolding mechanism, when the mold needs to be demolded, the telescopic rod drives the upper mold to move upward. Since the sliding rod is fixed on both sides of the upper mold, it drives the sliding rod to move together when the upper mold moves. When the upper mold and the lower mold are closed, the inclined block is engaged in the slot of the sliding rod. When the sliding rod moves upward, it pushes the inclined block inward. At this time, the inclined block is close to both sides of the stamping block, preventing the mold from sticking to the stamping block and moving upward with the stamping block. This effectively solves the problem of the mold sticking to the stamping block and moving with the stamping block, and effectively improves production efficiency.

[0017] 2. The present invention proposes a mold frame that facilitates demolding. By setting a second demolding mechanism and a sliding rod, when the upper mold and the lower mold are closed for operation, the sliding rod drives the second connecting plate downward together, and the demolding rod and demolding piece also move accordingly until the upper mold and the lower mold are tightly attached. The demolding piece enters the second groove. During demolding, the upper mold moves upward, driving the sliding rod to move. The sliding rod drives the second connecting plate to move upward. At the same time as it moves, the demolding piece pushes against the bottom end of the mold. As it moves upward, it pushes the mold out to complete the demolding, effectively increasing the convenience of demolding of the device. Attached Figure Description

[0026] Reference Figure 1 , Figure 2 , Figure 3 One embodiment provided by this utility model:

[0027] A mold frame for easy demolding includes a lower mold 3, with first demolding mechanisms 8 fixedly connected to both sides of the top of the lower mold 3, and second demolding mechanisms 11 fixedly installed at the bottom of the two first demolding mechanisms 8. Support columns 2 are fixedly connected to the bottom of the lower mold 3, and a mold frame base plate 1 is fixedly installed at the bottom of the support columns 2. A lower mold cavity 7 is opened in the middle of the top of the lower mold 3, and two second grooves 13 are opened at the bottom of the lower mold cavity 7. A connecting groove 14 is opened at the bottom of the two second grooves 13. Telescopic rods 4 are fixedly connected to the top of the lower mold 3, and an upper mold 5 is fixedly connected to the top of the multiple telescopic rods 4. First connecting plates 9 are fixedly installed on both sides of the top of the mold frame base plate 1, and a sliding groove 12 is opened on one side of the surface of the two first connecting plates 9. A stamping block 6 is fixedly connected to the middle of the bottom of the upper mold 5, and first grooves 10 are opened on both sides of the bottom of the upper mold 5.

[0028] Specifically, the lower mold 3 is used to connect and fix the first demolding mechanism 8. The first demolding mechanism 8 is used to prevent the mold from sticking to the heavy-duty stamping block 6 and being pulled out by the stamping block 6. The support column 2 is used to support the device and connect the mold base plate 1. The lower mold cavity 7 is used to facilitate the stamping block 6 to enter for mold processing. The second groove 13 and the connecting groove 14 are used to facilitate the movement of the second demolding mechanism 11 for demolding. The telescopic rod 4 is used to drive the upper mold 5 to move up and down. The first groove 10 on both sides of the bottom end of the upper mold 5 is used to prevent the device from being damaged by pressing the first demolding mechanism 8. The sliding groove 12 of the first connecting plate 9 is used to facilitate the movement of the sliding rod 801.

[0029] Reference Figure 4 The first demolding mechanism 8 includes a sliding rod 801 and an inclined block 807. A slot 804 is provided on one side of the surface of the sliding rod 801. A connecting rod 802 is fixedly connected to the surface of the inclined block 807. Guide rails 806 are slidably connected to both sides of the bottom end of the connecting rod 802. A fixing plate 803 is fixedly provided at one end of the two guide rails 806. A spring 805 is fixedly provided on one side of the surface of the fixing plate 803.

[0030] Specifically, the sliding rod 801 is fixed on both sides of the upper mold 5, the slot 804 is used to facilitate the insertion of the inclined block 807 and to facilitate the movement of the inclined block 807 when the sliding rod 801 moves, the connecting rod 802 is fixed on the surface of the inclined block 807, the guide rail 806 is used to facilitate linear movement, the fixing plate 803 is used to limit the movement range of the inclined block 807, and the spring 805 is used to facilitate the automatic entry of the inclined block 807 into the slot 804.

[0031] Reference Figure 5 The second demolding mechanism 11 includes a second connecting plate 1101, two demolding rods 1102 are fixedly provided at the bottom end of the second connecting plate 1101, and demolding pieces 1103 are fixedly provided at the top end of the two demolding rods 1102.

[0032] Specifically, the second connecting plate 1101 is fixed to the bottom end of the sliding rod 801, and the demolding rod 1102 is used to connect the demolding piece 1103. The demolding piece 1103 is used to facilitate the ejection of the mold for demolding.

[0033] Working principle: The upper mold 5 moves downward. As the upper mold 5 moves, the sliding rod 801 also moves downward, driving the second connecting rod 1101 downward together until the upper mold 5 is close to the lower mold 3. At this time, the inclined block 807 is inserted into the slot 804, and the demolding piece 1103 enters the second groove 13. When the mold needs to be demolded, the telescopic rod 4 drives the upper mold 5 to move upward. Since the sliding rod 801 is fixed on both sides of the upper mold 5, it moves along with the upper mold 5. When the upper mold 5 and the lower mold 3 are closed, the inclined block 807 is engaged in the slot 804 of the sliding rod 801. When the sliding rod 801 moves upward, it pushes the inclined block 807 inward. At this time, the inclined block 807 is close to both sides of the stamping block 6, preventing the mold from sticking to the stamping block 6 and moving upward together with the stamping block 6. This effectively solves the problem of the mold sticking to the stamping block 6 and moving with the stamping block, thus effectively improving production efficiency.

[0034] Secondly, the upper mold 5 moves upward, causing the sliding rod 801 to move. The sliding rod 801 causes the second connecting plate 1101 to move upward. At the same time, the demolding piece 1103 pushes against the bottom of the mold. As it moves upward, it pushes the mold out to complete the demolding, which effectively increases the convenience of demolding of the device.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
