Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a forming die for processing a motor shell. Background Art

[0002] The manufacture of motor housing is a very important part of the motor production process. Motor housings are made of aluminum, cast iron and plastic. Generally, small motors are made of plastic, medium-sized motors are made of aluminum housing using die-casting technology, and large motors are generally made of cast iron housing using casting technology. During the casting process of the motor housing, the injection molding material is introduced into the molding mold. The Chinese utility model patent with application number 2023219961132 discloses a motor housing lost foam mold, including a fixed mold and a movable mold arranged on one side of the fixed mold. The fixed mold and the movable mold are both provided with a cooling chamber for cooling by passing water, and the top of the fixed mold and the movable mold is fixedly installed with a water outlet pipe connected to the cooling chamber. The prior art mold is mainly composed of two mold groups, a fixed mold and a movable mold. Since the shape of the motor housing is irregular, it is inconvenient to quickly separate the molded housing mold. And the cooling components arranged in the fixed mold and the movable mold can only cool the outside of the molded original in the mold, and the cooling speed is slow. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-4 As shown: a forming mold for processing a motor housing, including a base 1, a plurality of linear guides 2 are fixedly installed on the top of the base 1, and the linear guides 2 are respectively installed in four directions of front, back, left and right. A long slider 3 is slidably arranged in each linear guide 2, and the long slider 3 is externally connected and driven by a motor to slide along the direction of the linear guide 2. In addition to the motor drive, the long slider 3 can also be set to be connected and driven by a cylinder. Since the drives belong to the existing technology, the specific drive structure will not be described in detail here.

[0024] A limit plate 4 is fixedly provided in the middle position of the top of the base 1. The limit plate 4 is rectangular and can limit the long slider 3 in four directions at the same time. Reinforcing ribs 41 are fixed in the horizontal and longitudinal directions of the middle position of the limit plate 4.

[0025] A module 5 is fixedly installed on the top of the long slider 3, and there are four modules 5. In order to ensure further stability of the module 5 structure, a total of 8 linear guide rails 2 are provided, 2 in each direction, and a module 5 is fixedly installed on the two long sliders 3 in each direction.

[0026] One of the modules 5 has an injection molding hole 51 on the top. When the long slider 3 slides toward the middle or the surroundings along the linear guide rail 2, the modules 5 can be combined and separated. When the modules 5 are combined, a cavity is formed inside, which is the molding shape of the motor housing.

[0027] A groove is provided on the top of the module 5, and a core 15 is hoisted on the top of the module 5. A lifting ring base 16 is fixedly installed on the top of the core 15, and a lifting ring 17 is fixedly installed on the lifting ring base 16. An external crane can realize the lifting operation of the core 15 through the lifting ring 17. Different cranes or lifting tools can be used according to the specific operating conditions on site. An upper cover plate 23 is also fixedly installed in the middle part of the core 15. When the core 15 is hoisted to the middle of multiple modules 5, the upper cover plate 23 is coupled with the grooves on the top of the multiple modules 5.

[0028] The upper cover plate 23 is provided with lower threaded holes 21 and upper threaded holes 22 around the periphery and on the grooves of the module 5. When the upper cover plate 23 is coupled with the grooves on the tops of the multiple modules 5, it is fixed by bolts 20, which can further ensure the sealed installation between the mold core 15 and the module 5. A cooling cavity 1 is provided inside the mold core 15, and an upper drain port 18 and an upper water inlet 19 of the cooling cavity 1 are fixed on the top of the mold core 15. After the injection molding is completed, the molded mold needs to be cooled and demolded. The coolant enters the cooling cavity 1 provided inside the mold core 15 through the upper water inlet 19 to cool the mold, and then the coolant is drained from the upper drain port 18.

[0029] Embodiment 2:

[0030] On the basis of the above structure, in order to increase the cooling demoulding effect of the device and the combined sealing degree between the modules 5, firstly, a cooling cavity 8 is opened inside each module 5, and the top and bottom of the module 5 are respectively fixedly provided with a water inlet 6 and a drain 7. In the first embodiment, a cooling system is set in the mold core 15 to quickly cool the inside of the mold being formed, while the cooling system added in the module 5 in this embodiment is to quickly cool the outside of the mold being formed. Therefore, the cooling system in the mold core 15 and the cooling system added in the module 5 cooperate with each other to cool the mold more quickly, thereby improving production efficiency.

[0031] In order to improve the sealing degree between each module 5, a locking assembly 9 is arranged on the top of the two connected modules 5, and the fixing seat 10 and the fixing seat 2 11 of the locking assembly 9 are fixedly installed on the two adjacent modules 5, wherein the fixing seat 2 11 is fixedly installed with a rotating shaft 12, and a threaded turning rod 13 is rotatably installed on the rotating shaft 12, and the threaded turning rod 13 is locked by the locking nut 14 when it rotates to the fixing seat 10. When the modules 5 are separated, the locking assembly 9 is in an open and closed state, and when the modules 5 are combined, the threaded turning rod 13 is turned over to the fixing seat 1 10, and then the locking nut 14 is tightened inwardly, so that the combined sealing degree between the modules 5 can be improved.

[0032] The working principle of the utility model is as follows: when the equipment is working, firstly, the long slider 3 at the bottom of the module 5 is used to combine it to the middle position, then the adjacent module 5 is locked by the locking assembly 9, and then the core 15 is hoisted into the cavity in the middle of the module 5 by the sling, and then the lower threaded hole 21 and the upper threaded hole 22 on the module 5 and the upper cover plate 23 are further fixed and sealed by the bolt 20, and then the injection molding material can be injected into the mold through the injection molding hole 51, and the coolant is injected into the cooling cavity in the core 15 and the module 5 during the injection molding process. When the injection molding is completed, After being formed, after cooling for a period of time, first start the lifting device to lift the core 15. During the lifting process, it is not necessary to lift it completely at this time, only the core 15 and the formed mold need to be demolded. Then start the driving motor or cylinder connected to the long slider 3 to make the module 5 slide in four directions to the outside respectively. Since the core 15 is not completely lifted at this time, the formed mold can be fixed in the middle position, and the module 5 can be demolded from the forming mold to the outside respectively. Then start the lifting device to lift the core 15, and then the forming mold can be easily removed.

[0033] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
