Description

Technical Field

[0001] The present invention relates to the field of motor manufacturing, and more particularly to a demolding structure for a motor core mold. Background Art

[0002] For the T-shaped stator of the motor core, in order to insulate, a plastic insulation layer is wrapped on the outer surface of the main body. The production process of the insulation layer is as follows: the main body is placed in the cavity of the mold, the molten insulation material is injected into the cavity, the insulation material forms an insulation layer in a specific area on the outer surface of the main body, and then the inserts in the cavity are withdrawn for demolding.

[0003] In the existing demolding structure, during demolding, a horizontal driving member needs to output power in the horizontal direction, resulting in a large overall volume of the mold and a large floor area, which is not conducive to the miniaturization of the equipment and the layout of the production line. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a demolding structure for a motor core mold with a small volume.

[0005] One of the purposes of the present invention is achieved by adopting the following technical solutions:

[0006] A demolding structure for a motor core mold includes a first demolding component and a second demolding component. The first demolding component includes a first driving member and a first sliding structure. The first driving member is provided with a first inclined surface, and the first sliding structure is provided with a mating surface. The mating surface is inclined and abuts against the first inclined surface. The first driving member is slidably connected to the first sliding structure. The first sliding structure includes a first insert. The second demolding component includes a second sliding structure. The second sliding structure is located on the same straight line as the first sliding structure and slides along the straight line. The second sliding structure includes a second sliding block and a second insert fixed to the second sliding block. The second sliding block is provided with a driving hole. The axis of the driving hole is inclined. The first insert and the second insert are butted to form at least part of the cavity. The cavity is used to accommodate the main body of the iron core and cast the insulation layer. The first driving member moves in the vertical direction to drive the first sliding structure to move in the horizontal direction. The guide post in the driving hole moves to drive the second sliding structure to move in the horizontal direction. The moving direction of the first sliding structure is opposite to that of the second sliding structure, so that the first insert and the second insert move in the opposite direction for demolding or mold closing.

[0007] Further, the inclination direction of the axis of the driving hole is opposite to the inclination direction of the first inclined surface, and the moving direction of the first driving member is the same as that of the guide post.

[0008] Further, the first insert block includes a fixing portion and two extending portions extending from the fixing portion. The two extending portions are parallel to each other and a slot is formed between the two extending portions. The slot forms a cavity, the side walls of the two extending portions form the side walls of the cavity, and one end of the slot close to the fixing portion forms the end wall of the cavity.

[0009] Further, a positioning protrusion is provided at one end of the extending portion away from the fixing portion, and a positioning hole is provided on the second insert block. When the first insert block is in butt joint and mold closing with the second insert block, the positioning protrusion is inserted into the positioning hole.

[0010] Further, the positioning protrusion is conical.

[0011] Further, the first sliding structure further includes a forming needle. The forming needle is fixed to the fixing portion, and the end of the forming needle extends out of the fixing portion and extends into the slot to form a conductive hole for the iron core in the cavity.

[0012] Further, the first sliding structure further includes a first sliding block and a first insert block assembly. The first sliding block is fixedly connected to the first insert block assembly. The first insert block assembly includes the first insert block. The first sliding block includes a sliding portion and a limiting portion. The sliding portion forms an installation groove. The limiting portion is fixed to the sliding portion and is located in the installation groove. The first driving member includes a main body and a convex edge extending from the main body. At least part of the main body is located in the installation groove, and the convex edge is located between the limiting portion and the sliding portion.

[0013] Further, the installation groove is U-shaped.

[0014] Further, the number of the first insert block assemblies is two. The two first insert block assemblies are parallel to each other, and a gap is formed between the two first insert block assemblies.

[0015] Further, the second demolding assembly further includes a first positioning block and a second positioning block. The first positioning block is fixedly connected to the second sliding structure. The number of the second positioning blocks is two, and the second sliding structure is slidably installed between the two second positioning blocks.

[0016] Compared with the prior art, the first driving member of the mold demolding structure of the motor iron core of the present invention is provided with a first inclined surface, and the first sliding structure is provided with a mating surface. The mating surface is inclined and abuts against the first inclined surface. The first driving member is slidably connected to the first sliding structure. The first sliding structure includes a first insert block. The second sliding structure of the second demolding assembly is located on the same straight line as the first sliding structure and slides along the straight line. The second sliding structure includes a second sliding block and a second insert block fixed to the second sliding block. The second sliding block is provided with a driving hole, and the axis of the driving hole is inclined. The first insert block and the second insert block are butted to form at least part of the cavity. The cavity is used to accommodate the main body of the iron core and cast the insulating layer. The first driving member moves in the vertical direction to drive the first sliding structure to move in the horizontal direction. The guide post in the driving hole moves to drive the second sliding structure to move in the horizontal direction. The moving direction of the first sliding structure is opposite to that of the second sliding structure, so that the first insert block and the second insert block move in opposite directions for demolding or mold closing. Through the above design, the vertical movement of the first driving member is converted into the horizontal movement of the first sliding structure, and the guide post in the driving hole converts the vertical movement into the horizontal movement of the second sliding structure, reducing the volume of the mold demolding structure of the motor iron core and facilitating the layout of the production line.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] Please refer to Figure 1, the demolding structure of the motor iron core mold of the present invention is used to manufacture the iron core 100, which includes a main body 101 and an insulating layer 102. The main body 101 is made of a conductive material, and the insulating layer 102 is coated on the surface of the main body 101 to insulate the iron core 100.

[0030] Please continue to refer to Figure 2 , the demolding structure of the motor iron core mold includes a first demolding component 10 and a second demolding component 20, and the first demolding component 10 and the second demolding component 20 are located on the same straight line.

[0031] Please continue to refer to Figure 2 and Figure 3 , the first demolding component 10 includes a first driving member 11 and a first sliding structure 12. The first driving member 11 is inclined and slidably connected to the first sliding structure 12, converting the vertical movement of the first driving member 11 into the horizontal movement of the first sliding structure 12.

[0032] Specifically, the first driving member 11 is inclined. The first driving member 11 includes a main body 111 and convex edges 112 extending from both sides of the main body 111. The main body 111 is provided with a first inclined surface 110, and the main body 111 is slidably installed on the first sliding structure 12, and the first inclined surface 110 is in contact with the first sliding structure 12.

[0033] The first sliding structure 12 includes a first sliding block 13 and a first insert block assembly 14. The first insert block assembly 14 is fixed to the first sliding block 13. The number of the first insert block assemblies 14 is two, and the two first insert block assemblies 14 are parallel to each other, and a gap 15 is formed between the two first insert block assemblies 14.

[0034] Please continue to refer to Figure 4 , the first sliding block 13 includes a sliding portion 131 and a limiting portion 132 fixed to the sliding portion 131. The sliding portion 131 is U-shaped to form a mounting groove, and the side wall of the mounting groove is a mating surface 130, and the mating surface 130 is inclined. A receiving groove 1310 is provided on the side of the sliding portion 131 away from the first driving member 11, and the receiving groove 1310 is used to mount the connecting block 140 of the first insert block assembly 14. The limiting portion 132 is located in the mounting groove, and the convex edge 112 of the first driving member 11 is located between the limiting portion 132 and the sliding portion 131, so that when the first driving member 11 moves vertically, it drives the first sliding structure 12 to move horizontally.

[0035] Please continue to refer to Figure 5 and Figure 6, the first insert block assembly 14 includes a connecting block 140, a forming pin 141, and a first insert block 142. The forming pin 141 is installed on the connecting block 140 and the end of the forming pin 141 extends out of the connecting block 140 to form a conductive hole 105. The first insert block 142 is fixed to the connecting block 140 and the first insert block 142 is used to form a cavity. Specifically, the first insert block 142 includes a fixing portion 1420 and two extending portions 1421. The two extending portions 1421 extend from the fixing portion 1420. The two extending portions 1421 are parallel to each other and are spaced apart. A slot 1423 is formed between the two extending portions 1421, and the slot 1423 is used to form a cavity. The inner side walls of the two extending portions 1421 form the inner wall of the cavity. A positioning protrusion 1422 is provided at the end of the extending portion 1421, and the positioning protrusion 1422 is used to be inserted into the positioning hole 2101 of the second insert block 210 to realize the positioning of the first insert block 142 and the second insert block 210.

[0036] Please continue to refer to Figure 7 , the second demolding assembly 20 includes a second sliding structure 21, a first positioning block 22, and a second positioning block 23. The second sliding structure 21 includes two second insert blocks 210 and a second sliding block 211. The two second insert blocks 210 are fixed to the second sliding block 211. The two second insert blocks 210 are parallel to each other and are spaced apart, so that the demolding structure of the motor core mold can produce two cores 100 at the same time. The second sliding block 211 is provided with a driving hole 2110. The driving hole 2110 is inclined in the vertical direction. A guide post is installed in the driving hole 2110. When the guide post moves in the vertical direction, it drives the second sliding structure 21 to move in the horizontal direction. In this embodiment, the inclination direction of the axis of the driving hole 2110 is opposite to the inclination direction of the first inclined surface 110, so that when the first driving member 11 and the guide post move in the same direction (both upward or downward at the same time), the first sliding structure 12 and the second sliding structure 21 can move in the opposite direction for demolding or mold closing. The first positioning block 22 is fixed to the second sliding block 211. The number of the second positioning blocks 23 is two. The two second positioning blocks 23 are fixed to both sides of the mold base. The second sliding structure 21 is slidably installed between the two second positioning blocks 23. The second positioning block 23 is provided with a locking hole 230, and the locking hole 230 is used to install a bolt to fix the second positioning block 23 to the base.

[0037] Please continue to refer to Figure 8, when the demoulding structure of the motor core die is in use, the first insert block 142 and the second insert block 210 are inserted and in the closed die state. At this time, the positioning protrusion 1422 of the first insert block 142 is inserted into the positioning hole 2101 of the second insert block 210, and a cavity is formed by the side wall of the first insert block 142, the end of the fixing part 1420 and the end of the second insert block 210. When using the demoulding structure of the motor core die, the main body 101 of the iron core 100 is placed in the slot 1423, and the molten insulating material is injected into the gap between the main body 101 and the cavity to form an insulating layer 102, and the insulating layer 102 covers a preset position of the main body 101. After the insulating layer 102 cools, the first driving member 11 and the guide post move upward simultaneously. The first driving member 11 drives the first sliding structure 12 to move leftward, and the guide post drives the second sliding structure 21 and the first positioning block 22 to move rightward, and the first insert block 142 is separated from the second insert block 210 to realize demoulding. After taking out the iron core 100 after injection molding, the first driving member 11 and the guide post move downward simultaneously. The first driving member 11 drives the first sliding structure 12 to move rightward, and the guide post drives the second sliding structure 21 and the first positioning block 22 to move leftward, and the positioning protrusion 1422 is inserted into the positioning hole 2101 of the second insert block 210. At this time, the demoulding structure of the motor core die is reset for the next injection molding.

[0038] The demoulding structure of the motor core die in this application converts the vertical movement of the first driving member 11 into the horizontal movement of the first sliding structure 12, and the guide post in the driving hole 2110 converts the vertical movement into the horizontal movement of the second sliding structure 21, reducing the volume of the demoulding structure of the motor core die and facilitating the layout of the production line.

[0039] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essential technology of the present invention, and these all belong to the protection scope of the present invention.
