Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a molding mold. Background Art

[0002] When producing electronic products, it is usually necessary to place iron parts in a mold and injection mold them together with plastic. When the workpiece is placed vertically in the mold, in order to position the iron parts, it is usually necessary to add a connecting structure to the iron parts, which causes waste of iron parts materials. In addition, the connecting structure needs to be removed again after the product is formed, which increases the processing cost. Therefore, it is necessary to improve the current mold so that the iron parts can be accurately positioned in the mold without adding an iron parts connecting structure, thereby achieving the positioning of the iron parts and reducing the waste of iron parts.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0078] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0079] See also Figure 1 and Figure 2 The embodiment of the present application provides a molding die 100. The molding die 100 is used for injection molding a workpiece 200 and plastic. The workpiece 200 is generally a sheet-like structure. During the molding process, the workpiece 200 is clamped and fixed in the molding die 100.

[0080] For ease of understanding, Figure 1 A three-dimensional coordinate system is established for auxiliary explanation. The directions of the X-axis, Y-axis and Z-axis are shown in the figure. The X-axis, Y-axis and Z-axis are perpendicular to each other, wherein the X-axis direction is defined as the third direction, and the Z-axis direction is defined as the first direction.

[0081] The molding die 100 includes a female mold mechanism 10 and a male mold mechanism 20, which are arranged opposite to each other. The female mold mechanism 10 and the male mold mechanism 20 are closed to mold the workpiece 200 and the plastic together, and the female mold mechanism 10 and the male mold mechanism 20 are opened to take out the material.

[0082] See also Figure 3 The female mold mechanism 10 includes a female mold base 11 and a contact block 12. The female mold base 11 is used for closing the mold with the male mold mechanism 20. The contact block 12 is arranged on the side of the female mold base 11 facing the male mold mechanism 20 and extending along the second direction. The second direction is arranged at an angle with the first direction. The female mold base 11 supports the contact block 12.

[0083] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The male mold mechanism 20 includes a male mold base 21, a holding assembly 22 and a linkage assembly 23. The male mold base 21 and the female mold base 11 are arranged relative to each other for cooperating with the female mold base 11 for mold closing. A groove 2121 extending along the X-axis direction is arranged on one side of the male mold base 21 facing the female mold base 11.

[0084] The abutting assembly 22 is movably arranged in the groove 2121. It should be noted that in the initial state, the abutting assembly 22 abuts against the male mold seat 21. When the workpiece 200 is placed, the workpiece 200 is directly inserted between the abutting assembly 22 and the male mold seat 21, and the abutting assembly 22 abuts the workpiece 200 against the male mold seat 21. The linkage assembly 23 is movably installed on the male mold seat 21. The linkage assembly 23 is provided with a first inclined surface 2311 (such as Figure 6 ).

[0085] See also Figure 6 When the male mold base 21 and the female mold base 11 are molded, the abutment block 12 is slidably inserted in the linkage component 23 and abuts against the first inclined surface 2311, so that the linkage component 23 slides relative to the male mold base 21 along the X-axis direction and is linked to the abutment component 22. When the male mold base 21 and the female mold base 11 are molded, the linkage component 23 and the abutment component 22 form a clamping relationship, avoiding the linkage component 23 from moving in the opposite direction of the X-axis, thereby ensuring the reliability of the mold closing. Among them, after the mold closing, the male mold base 21, the female mold base 11 and the linkage component 23 are surrounded to form a mold cavity 30. It should be noted that part of the structure of the workpiece 200 will extend into the mold cavity 30. In other embodiments, the workpiece 200 can also be completely located in the mold cavity 30. At this time, the rubber is injected into the mold cavity 30, and the rubber is wrapped around the peripheral side of the part of the structure of the workpiece 200. When the rubber is cooled and formed, the workpiece 200 is formed together with the rubber.

[0086] See also Figure 2 and Figure 7 When the male mold base 21 and the female mold base 11 are opened, the abutment block 12 slides out the linkage assembly 23. At this time, the linkage assembly 23 slides in the opposite direction along the male mold base 21 and drives the abutment assembly 22 away from the workpiece 200, thereby releasing the workpiece 200.

[0087] When the workpiece 200 is placed in the groove 2121, the abutting assembly 22 abuts the workpiece 200 against the male mold base 21 to position the workpiece 200, thereby preventing the injection position of the workpiece 200 from being offset when the rubber is injected. By adopting the above-mentioned molding die 100, the positioning of the workpiece 200 can be achieved without designing a connection structure on the workpiece 200, and the process of adding a cutting process of the connection structure is avoided, thereby not only saving the material of the workpiece 200 but also simplifying the process.

[0088] See also Figure 3 and Figure 6 In this embodiment, a punch 13 is provided on one side of the female mold base 11 facing the male mold base 21, and is spaced apart from the abutment block 12 along the X-axis direction, and the distance between the abutment block 12 and the punch 13 gradually increases from the end close to the female mold base 11 to the end away from the female mold base 11. When the male mold base 21 and the female mold base 11 are molded together, the punch 13 is used to surround the male mold base 21 and the linkage assembly 23 to form a mold cavity 30.

[0089] See also Figure 1 and Figure 6 The molding die 100 further includes a limiting mechanism 40 and a pusher 50. When the mold is opened, when the linkage assembly 23 drives the abutting assembly 22 to release the workpiece 200, the limiting mechanism 40 is inserted and matched with the abutting assembly 22 to limit the abutting assembly 22. The pusher 50 is used to push the workpiece 200 out of the groove 2121 after the mold is opened to realize demolding of the workpiece 200.

[0090] See also Figure 4 and Figure 6 The male mold base 21 includes a base 211, an insert 212 and a locking block 213. The base 211 is arranged opposite to the female mold base 11 and can be matched with the female mold base 11. The insert 212 is embedded in the middle of the side of the base 211 facing the female mold base 11. The insert 212 can be used to form a mold cavity 30 with the male mold 13 and the linkage assembly 23. The groove 2121 is opened on the side of the insert 212 facing the female mold base 11, and the groove 2121 is used to limit the sliding direction of the abutting assembly 22.

[0091] See also Figure 1 , Figure 6 and Figure 8 The insert 212 is also provided with a receiving chamber 214 and a communicating hole 215. The receiving chamber 214 is located on the side of the insert 212 away from the groove 2121. The groove 2121 is connected to the receiving chamber 214 through the communicating hole 215. The limiting mechanism 40 is provided in the receiving chamber 214. The locking block 213 is connected to the insert 212 by bolts, and the limiting mechanism 40 is limited in the receiving chamber 214.

[0092] The insert 212 is also provided with a through hole 216, which is arranged along the Z-axis direction and communicated with the groove 2121. The through hole 216 is used to accommodate the pusher 50. The end of the pusher 50 abuts against the bottom surface of the workpiece 200. When the pusher 50 is pushed, the pusher 50 can push the workpiece 200 out. The pusher 50 can be driven by a cylinder or an oil cylinder.

[0093] See also Figure 2 and Figure 5 The abutting assembly 22 includes an abutting member 221 and a first elastic member 222. The abutting member 221 is slidably disposed in the groove 2121 along the X-axis direction, and the abutting member 221 is used to abut against the workpiece 200. A positioning portion 223 is provided at one end of the abutting member 221, and the positioning portion 223 can be plugged and matched with the workpiece 200 for plugging and positioning the workpiece 200. Specifically, the positioning portion 223 is hemispherical.

[0094] The first elastic member 222 can be a spring, and the first elastic member 222 is compressed and arranged between the male mold base 21 and the abutting member 221. The two ends of the first elastic member 222 are respectively abutted against the insert 212 of the male mold base 21 and one end of the abutting member 221 away from the positioning portion 223. When the workpiece 200 is placed in the groove 2121, the abutting member 221 elastically presses the workpiece 200 against the insert 212 under the elastic action of the first elastic member 222. At this time, the abutting member 221 and the insert 212 clamp and position the workpiece 200. It should be noted that in the initial state, the abutting member 221 is always abutted against the insert 212 under the action of the first elastic member 222.

[0095] See also Figure 5 and Figure 6 In this embodiment, a slot 224 is provided on the side of the abutting member 221 facing the female mold base 11, and the slot 224 is used to be plugged and matched with the linkage assembly 23. The linkage assembly 23 includes a sliding member 231, a second elastic member 232 and a connecting member 233. The sliding member 231 is slidably arranged on the male mold base 21 along the X-axis direction, and the sliding member 231 is provided with sliding holes 234 and mounting grooves 235 arranged at intervals along the X-axis direction. Specifically, the sliding member 231 includes a slider 236 and a cover plate 237. The slider 236 is used to surround the punch 13 and the insert 212 to form a mold cavity 30 when the male mold base 21 and the female mold base 11 are molded together. The sliding hole 234 and the mounting groove 235 are provided on the slider 236, and the cover plate 237 is provided on the side of the slider 236 away from the abutting member 221. The first inclined surface 2311 is the hole wall of the sliding hole 234, and the abutting block 12 can be slidably inserted into the sliding hole 234 and abut against the first inclined surface 2311. The connecting member 233 is a stepped structure, that is, one end of the connecting member 233 is smaller in size, and the other end of the connecting member 233 is larger in size. The larger end of the connecting member 233 is slidably provided in the mounting groove 235 along the Z-axis direction and abuts against the groove wall of the mounting groove 235, so that the connecting member 233 can stably slide in the mounting groove 235. The groove bottom of the mounting groove 235 is provided with a hole structure for the smaller end of the connecting member 233 to pass through. The connecting member 233 can slide to a position corresponding to the card groove 224 following the sliding member 231.

[0096] The second elastic member 232 may be a spring, and both ends of the second elastic member 232 are respectively in contact with the cover plate 237 of the sliding member 231 and the connecting member 233 . The second elastic member 232 is compressed and disposed between the cover plate 237 of the sliding member 231 and the connecting member 233 .

[0097] See also Figure 6In the implementation process of the linkage assembly 23, when the mold is closed, the abutment block 12 is inserted into the sliding hole 234 of the sliding member 231. At this time, the abutment block 12 drives the sliding member 231 to slide toward the workpiece 200. When the connecting member 233 installed on the sliding member 231 is aligned with the card slot 224 on the abutting member 221, the connecting member 233 is inserted into the card slot 224 under the action of the second elastic member 232. At this time, the slider 236 and the abutting member 221 form a card connection relationship. After the mold is closed, the sliding member 231, the punch 13 and the insert 212 are surrounded to form the mold cavity 30. When the mold is opened, the connecting member 233 can drive the abutting member 221 to move away from the workpiece to release the workpiece 200.

[0098] In another embodiment, the connecting member 233 and the second elastic member 232 may be disposed on the abutting member 221, and the slot 224 may be disposed on the sliding member 231. When the mold is closed, when the slot 224 on the sliding member 231 moves to a position opposite to the connecting member 233, the connecting member 233 is plugged into the slot 224 under the action of the second elastic member, and at this time, the sliding member 231 and the abutting member 221 may also form a linkage connection.

[0099] See also Fig. 9 The molding die 100 further includes a limiting mechanism 40, which includes a limiting component 41 telescopically arranged in the accommodating cavity 214 along the Z-axis direction and an unlocking component 42 moving along the X-axis direction.

[0100] See also Figure 5 and Figure 6 A limiting groove 2211 is provided on the side of the supporting member 221 away from the card slot 224 , and the limiting groove 2211 is used for plugging and matching with the limiting component 41 .

[0101] See also Figure 2 , Figure 5 , Figure 7 and Fig. 9The groove wall of the groove 2121 is provided with a guide groove 217 connected with the clamping groove 224. In the embodiment, there are two guide grooves 217, and the two guide grooves 217 are respectively located on the groove wall of the groove 2121 along the Y-axis direction. The groove wall of the guide groove 217 away from the positioning portion 223 is inclined, and the guide groove 217 is used to accommodate a part of the structure of the connecting member 233. When the connecting member 233 is inserted into the clamping groove 224, the end of the connecting member 233 protrudes into the guide groove 217. When the sliding member 231 moves in a direction away from the workpiece 200 with the abutting member 221 through the connecting member 233, the connecting member 233 will also slide along the inclined groove wall of the guide groove 217. At this time, the connecting member 233 drives the abutting member 221 to move, and gradually withdraws from the clamping groove 224 under the guidance of the inclined groove wall of the guide groove 217. When the connecting member 233 withdraws from the slot 224 , the limiting groove 2211 corresponds to the limiting component 41 . At this time, the limiting component 41 passes through the communicating hole 215 and is inserted into the limiting groove 2211 to limit the abutting member 221 .

[0102] See also Figure 8 and Fig. 9 In this embodiment, the limiting assembly 41 includes a limiting member 411 and a third elastic member 412. The limiting member 411 is slidably disposed in the accommodating cavity 214 along the Z-axis direction.

[0103] See also Fig. 9 In this embodiment, the position-limiting member 411 includes a main body 4111 and a position-limiting portion 4112. Two vertical blocks 2131 are convexly disposed on the top surface of the locking block 213. The two vertical blocks 2131 are spaced apart along the X-axis direction. The main body 4111 is slidably disposed between the two vertical blocks 2131. When the main body 4111 slides along the Z-axis direction, the two vertical blocks 2131 guide the main body 4111.

[0104] See also Figure 5 and Fig. 9 The limiting portion 4112 is disposed on a side of the main body 4111 away from the locking block 213 , the top of the limiting portion 4112 is arc-shaped, and the limiting portion 4112 is adapted to the limiting groove 2211 .

[0105] See also Figure 6 , Figure 8 and Fig. 9 The third elastic member 412 may be a spring, and the third elastic member 412 is disposed in the accommodating cavity 214. The two ends of the third elastic member 412 are respectively in contact with the locking block 213 and the limiting member 411 of the male mold base 21, and the third elastic member 412 is compressed and disposed between the locking block 213 and the limiting member 411 of the male mold base 21. When the abutting member 221 slides to a position where the limiting groove 2211 corresponds to the limiting portion 4112, the limiting portion 4112 is inserted into the limiting groove 2211 under the elastic action of the third elastic member 412, thereby limiting the abutting member 221.

[0106] In this embodiment, a receiving groove 218 for accommodating a partial structure of the third elastic member 412 may be provided on the locking block 213. A partial structure of the third elastic member 412 is accommodated in the receiving groove 218, and a partial structure of the third elastic member 412 protrudes out of the receiving groove 218 and abuts against the limiting member 411. Through such a configuration, the third elastic member 412 can be fixed.

[0107] See also Figure 5 , Figure 8 and Fig. 9 The unlocking assembly 42 is used to drive the limiting assembly 41 to exit the limiting groove 2211 so that the abutting member 221 can be reset under the action of the first elastic member 222, so that the limiting assembly 41 can abut against the next workpiece 200 again. Specifically, the unlocking assembly 42 includes an unlocking member 421 and a fourth elastic member 422. The unlocking member 421 is slidably arranged in the accommodating cavity 214 along the X-axis direction, and an unlocking groove 4211 is provided on the side of the unlocking member 421 facing the main body 4111, and the groove wall of the unlocking groove 4211 close to the positioning portion 223 is an inclined wall, and the unlocking groove 4211 of the unlocking member 421 and the main body 4111 of the limiting member 411 are plugged and matched. For example, a matching inclined surface 4113 is provided on the main body 4111, and the matching inclined surface 4113 and the limiting portion 4112 are arranged at intervals, and the matching inclined surface 4113 abuts against the inclined wall of the unlocking groove 4211.

[0108] The fourth elastic member 422 may be a spring, and the fourth elastic member 422 is located in the accommodating cavity 214. Two ends of the fourth elastic member 422 are respectively in contact with the insert 212 of the male mold base 21 and the unlocking member 421, and the fourth elastic member 422 is compressed and arranged between the insert 212 of the male mold base 21 and the unlocking member 421. The fourth elastic member 422 is used to push the unlocking member 421 to move toward the workpiece 200 so that the unlocking member 421 is reset.

[0109] When the restriction of the abutting member 221 needs to be released, the unlocking member 421 is driven to move in a direction away from the workpiece 200. At this time, the inclined groove wall of the unlocking groove 4211 presses against the matching inclined surface 4113, so that the limiting member 411 exits the limiting groove 2211. After the limiting member 411 releases the restriction on the abutting member 221, the first elastic member 222 pushes the abutting member 221 to return to its original position and abut against the male mold base 21, so as to wait for the next workpiece 200 to be clamped. It can be understood that the unlocking member 421 can be driven by a cylinder.

[0110] In order to avoid setting up an additional mechanism to drive the unlocking member 421 to move, in this embodiment, the accommodating cavity 214 is communicated with the through hole 216, and a push-pushing inclined surface 51 is provided on the pusher 50, and the push-pushing inclined surface 51 is arranged toward the unlocking member 421, and a driven inclined surface 4212 is provided on the side of the unlocking member 421 facing the pusher 50. When the pusher 50 demoulds the workpiece 200, the push-pushing inclined surface 51 abuts against the driven inclined surface 4212 and pushes the unlocking member 421 to move in a direction away from the workpiece 200 through the driven inclined surface 4212, and at this time, the unlocking member 421 presses the limiting member 411 so that the limiting member 411 releases the restriction on the holding member 221.

[0111] See also Figure 1 and Figure 3 In order to accurately close the mold of the male mold base 21 and the female mold base 11, two spaced positioning holes 111 are provided on the side of the female mold base 11 facing the male mold base 21. The molding mold 100 also includes two positioning pins 60. The two positioning pins 60 are spaced apart on the side of the male mold base 21 facing the female mold base 11. Specifically, the positioning pins 60 are provided on the insert 212. The two positioning pins 60 correspond to the two positioning holes 111 one by one, and are respectively inserted into the corresponding positioning holes 111 to position the female mold base 11 when closing the mold.

[0112] The working process of the molding die 100 provided in the embodiment of the present application is roughly as follows:

[0113] In the initial state, the positioning portion 223 of the supporting member 221 is supported against the insert 212 under the action of the first elastic member 222, and the workpiece 200 is inserted between the supporting member 221 and the insert 212. At this time, the workpiece 200 pushes the supporting member 221 backward. When the hole on the workpiece 200 corresponds to the positioning portion 223, the positioning portion 223 is inserted into the workpiece 200 and the supporting member 221 elastically supports the workpiece 200 against the insert 212 under the action of the first elastic member 222.

[0114] When the male mold base 21 and the female mold base 11 are molded together, the abutment block 12 is inserted into the sliding member 231 and drives the sliding member 231 to slide, so that the connecting member 233 on the sliding member 231 is aligned with the slot 224. Under the action of the second elastic member 232, the connecting member 233 is inserted into the slot 224, and the end of the connecting member 233 protrudes into the guide groove 217. After the mold is closed, the female mold base 11, the sliding member 231 and the male mold base 21 are surrounded to form a mold cavity 30. Then, the rubber is injected into the mold cavity 30, and after the rubber is cooled, the rubber and the workpiece 200 are formed into one body.

[0115] When the male mold base 21 and the female mold base 11 are opened, the abutment block 12 and the sliding member 231 slide relative to each other, and the abutment block 12 drives the sliding member 231 to move in a direction away from the workpiece 200, and at the same time, the connecting member 233 on the sliding member 231 drives the abutment member 221 to move to release the workpiece 200. When the connecting member 233 drives the abutment member 221 to move, the connecting member 233 drives the abutment member 221 to release the workpiece 200 while sliding along the guide groove 217, and gradually withdraws from the slot 224 under the guidance of the inclined slot wall of the guide groove 217. When the connecting member 233 withdraws from the slot 224, the limiting groove 2211 on the abutment member 221 corresponds to the limiting member 411, and the limiting member 411 is inserted into the limiting groove 2211 under the action of the third elastic member 412 to limit the abutment member 221.

[0116] The pushing member 50 is pushed to make the workpiece 200 disengage from the groove 2121. At the same time, the pushing inclined surface 51 on the pushing member 50 pushes the driven inclined surface 4212 on the unlocking member 421 and makes the unlocking member 421 move away from the workpiece 200. At this time, the unlocking member 421 presses the limiting member 411 to make the limiting member 411 away from the limiting groove 2211. The supporting member 221 is reset under the action of the first elastic member 222 to wait for the installation of the next workpiece 200.
