Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a multi-station die-casting mold for motor covers. Background Technology

[0002] Mold manufacturing technology refers to the technology of processing metals or other materials into molds with specific shapes and sizes using mechanical, physical, or chemical methods.

[0003] Multi-station die-casting molds for motor covers are a special type of mold primarily used for the mass production of motor covers. Their multi-station design significantly improves production efficiency and reduces costs. These molds typically consist of multiple parts that fit together precisely to form the motor cover.

[0004] In existing technologies, when some multi-station die-casting molds extrude objects, the pressure plate at the top is continuously subjected to force. When the mold to be die-cast is uneven, the pressure plate will tilt, making it impossible to seal with the mold at the bottom, thus causing die-casting failure. To address this issue, a multi-station die-casting mold for motor covers is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a multi-station die-casting mold for motor covers, which aims to improve the problem in some existing multi-station die-casting molds where the pressure plate at the top is continuously subjected to force when extruding objects. When the mold to be die-cast is uneven, the pressure plate will tilt, making it unable to seal with the mold at the bottom, thus causing die-casting failure.

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

[0007] A multi-station die-casting mold for motor covers includes a machine body. A control panel is fixedly connected to one side of the machine body. An ejector assembly for easy object removal is fixedly connected to the inner wall of the machine body. A template is fixedly connected to the inner wall of the machine body. A cylinder is fixedly connected to the top of the inner wall of the machine body. A pressure plate is fixedly connected to the drive end of the cylinder. Multiple outer columns are fixedly connected to the top of the pressure plate. Inner columns are slidably connected to the inner walls of the outer columns. Limit blocks are fixedly connected to the top of the inner columns. Springs are sleeved on the outside of the inner columns.

[0008] As a further description of the above technical solution:

[0009] The ejection assembly includes a cylinder, the outer side of which is fixedly connected to the inner wall of the machine body. A top plate is fixedly connected to the drive end of the cylinder, and multiple sealing posts are fixedly connected to the top of the top plate.

[0010] As a further description of the above technical solution:

[0011] One end of the spring is fixedly connected to the top of the machine body, and the other end of the spring is fixedly connected to the bottom of the limiting block;

[0012] As a further description of the above technical solution:

[0013] A water tank is fixedly connected to one side of the machine body, a water pump is fixedly connected to the inner wall of the water tank, a delivery pipe is fixedly connected to the output end of the water pump, and a water sprayer is fixedly connected to the other end of the delivery pipe.

[0014] As a further description of the above technical solution:

[0015] A confluencer is fixedly connected to one side of the pressure plate, and a flexible hose is fixedly connected to the bottom end of the confluencer. A filter plate is detachably connected to the inner wall of the water bucket.

[0016] As a further description of the above technical solution:

[0017] The top plate is externally slidably connected to the inner wall of the machine body, and the sealing column is externally slidably connected to the inner wall of the template;

[0018] As a further description of the above technical solution:

[0019] The outer column is slidably connected to the inner wall of the machine body, and the bottom end of the water sprayer is fixedly connected to the top end of the machine body;

[0020] As a further description of the above technical solution:

[0021] The hose is fixedly connected to the outside of the pressure plate, and the other end of the hose is fixedly connected to the inner wall of the top of the bucket.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when cylinder two drives the pressure plate to descend and die-cast the object at the top of the template, the outer column here will descend together with the pressure plate, thereby ensuring that the pressure plate descends and squeezes smoothly when it cooperates with the template to die-cast the object, ensuring the sealing during die casting and guaranteeing the success of the die casting. In addition, after the die casting is completed, cylinder one can be controlled to lift the top plate and sealing column upward, thereby pushing out the die-cast motor cover for easy collection by the staff.

[0024] 2. In this utility model, when the pressure plate contacts the template to die-cast the object, the water pump is started to draw clean water from the inside of the water tank and spray it on the top of the pressure plate to cool and set the die-cast object. Because a groove is opened at the top of the pressure plate and the shape inside is higher on the left and lower on the right, the cooling water will flow into the confluencer and then flow back into the water tank through the hose. After being filtered by the filter plate, it can be reused, reducing water consumption and thus saving costs. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a multi-station die-casting mold for a motor cover, comprising a machine body 1, which is the main body of a die-casting machine. A control panel 2 is fixedly connected to one side of the machine body 1. The control panel 2 is used to control the switch of the machine body 1, the setting of various parameters, and the start of the mechanism. An ejection assembly for facilitating the removal of objects is fixedly connected to the inner wall of the machine body 1. The ejection assembly includes a cylinder 3. The cylinder 3 is fixedly connected to the inner wall of the machine body 1, and the machine body 1 provides stable support for the cylinder 3. A top plate 4 is fixedly connected to the drive end of the cylinder 3. After the cylinder 3 is started, it can drive the top plate 4 to rise.

[0033] The top plate 4 is externally slidably connected to the inner wall of the machine body 1. Multiple sealing columns 5 are fixedly connected to the top of the top plate 4. A template 6 is fixedly connected to the inner wall of the machine body 1. The sealing columns 5 are externally slidably connected to the inner wall of the template 6. When the top plate 4 rises, it can drive the sealing columns 5 to rise, thereby ejecting the die-cast object for easy collection by workers. A cylinder 7 is fixedly connected to the top of the inner wall of the machine body 1. A pressure plate 8 is fixedly connected to the drive end of the cylinder 7. After the cylinder 7 is started, it can drive the pressure plate 8 to descend. Multiple outer columns 9 are fixedly connected to the top of the pressure plate 8. The outer columns 9 are externally slidably connected to the inner wall of the machine body 1. An inner column 10 is slidably connected to the inner wall of the outer columns 9. The outer columns 9 provide a stable sliding space for the inner columns 10.

[0034] A limiting block 11 is fixedly connected to the top of the inner column 10. The limiting block 11 here limits the maximum distance of the outer column 9 to descend. A spring 12 is sleeved on the outside of the inner column 10. One end of the spring 12 is fixedly connected to the top of the machine body 1, and the other end of the spring 12 is fixedly connected to the bottom of the limiting block 11. The spring 12 here is used to reset the pressure plate 8 after the die casting of the object is completed in conjunction with the template 6.

[0035] Reference Figures 3 to 4 A water tank 13 is fixedly connected to one side of the machine body 1, providing stable support for the water tank 13. A groove is opened at the top of the water tank 13 for adding an initial amount of clean water. A water pump 14 is fixedly connected to the inner wall of the water tank 13, drawing out the clean water. A delivery pipe 15 is fixedly connected to the output end of the water pump 14, and a water sprayer 16 is fixedly connected to the other end of the delivery pipe 15. The delivery pipe 15 further delivers clean water to the inside of the water sprayer 16, which then sprays it into the groove at the top of the pressure plate 8 for cooling and shaping the die-cast object. The bottom end of the water sprayer 16 is fixedly connected to the top of the machine body 1. A confluencer 17 is fixedly connected to one side of the pressure plate 8. Because the groove in the pressure plate 8 is higher on the left and lower on the right, the cooling water flows to the right after cooling and shaping the object, until it flows into the confluencer 17.

[0036] A hose 18 is fixedly connected to the bottom of the confluence 17. The outside of the hose 18 is fixedly connected to the outside of the pressure plate 8. After the cooling water enters the interior of the confluence 17, it is further transported through the hose 18. The other end of the hose 18 is fixedly connected to the top inner wall of the water tank 13. A filter plate 19 is detachably connected to the inner wall of the water tank 13. After the cooling water is returned to the interior of the water tank 13 through the hose 18, it is filtered by the filter plate 19 and then pumped out by the water pump 14 for use, which reduces the input of water resources and saves costs.

[0037] Working principle: First, the operator places the raw material to be die-cast onto the top of the template 6. Then, the cylinder 7 is activated, causing the pressure plate 8 to descend. Simultaneously, the inner column 10 descends and slides along the inner wall of the outer column 9, ensuring the smooth descent of the pressure plate 8 and preventing air leakage due to the merging of the pressure plate 8 and template 6, which could lead to die-casting failure. At the same time, the machine body 1 and the limiting block 11 work together to compress the spring 12, causing it to contract and generate a reaction force. This step is for the subsequent reset operation of the pressure plate 8 after die-casting is completed.

[0038] When the pressure plate 8 contacts the template 6 and begins die casting of the raw material, the water pump 14 can be started to draw clean water from inside the water tank 13. This water is then transported along the conveying pipe 15 to the inside of the sprayer 16 and sprayed into the groove at the top of the pressure plate 8. Because the groove is higher on the left and lower on the right, the cooling water flows from left to right, cooling the object before flowing into the confluencer 17. Subsequently, it is transported back into the water tank 13 along the hose 18, filtered by the filter plate 19, and then drawn back out by the water pump 14 for reuse, reducing water consumption and saving costs.

[0039] After die casting is completed, the reaction force of spring 12 controls cylinder 2 7 to drive the pressure plate 8 to quickly reset. At the same time, cylinder 1 3 is activated, causing it to drive the top plate 4 and sealing column 5 to move upward. At this time, the sealing column 5 will push out multiple objects that are wrapped around the template 6, making it easier for workers to collect them.

[0040] 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.
