An injection cavity is formed between the fixed template, the core, and the movable template. An insert is arranged in the cavity, and the insert can divide the cavity. The layout of the insert directly determines the shape of the injection molding.

[0003] After investigation, the publication number: CN217044730U discloses a processing tool for inclined holes of mold inserts. In this technology, it is disclosed that "it includes a mold base and a module rotatably connected to the mold base. A locking component is arranged between the mold base and the module to fix the module at a specified angle. A processing hole is penetrated through the module, and an inner support is coaxially arranged in the processing hole. A retaining edge is arranged on the inner side of the bottom end of the inner support. A moving mechanism is arranged on the module to drive the inner support to move axially along the processing hole" and other technical solutions, and has technical effects such as "effectively meeting the processing needs of inclined holes at different angles, facilitating the processing of inclined holes of inserts, expanding the application range of inclined hole processing, and improving production efficiency".

[0004] In the actual processing and production process of the above-mentioned processing tool, due to the diversification of the specifications of mold inserts, when facing the processing requirements of irregular shapes or the need to stably fix multiple mold inserts at the same time, the fixing method of the tool is not flexible and convenient enough, thus affecting the processing efficiency and operation convenience. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a processing tool for inclined holes of inserts based on an injection mold, which has the characteristics of quickly positioning the insert, avoiding shaking when the insert tilts subsequently, and only requiring one servo motor to control multiple positioning mechanisms to be used synchronously to realize the simultaneous positioning of multiple inserts.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A processing tool for inclined holes of inserts based on an injection mold includes a table board. An adjusting mechanism is arranged on the table board and is used to adjust the processing angle of the inclined holes of the insert. A positioning mechanism is arranged on the table board and is used to position the insert. The positioning mechanism includes:

[0007] A main body component, including several bases fixed on the top of the table board, a pedestal fixed on the top of the base, a guide rail fixed on the upper end of the pedestal, a first slider and a second slider slidably installed on the guide rail, and a chuck and a clamp seat respectively installed on the first slider and the second slider;

[0008] The driving component includes a triangular block rotatably mounted at the bottom of the base, a first rod and a second rod pivotally connected to both ends of the triangular block respectively, and the ends of the first rod and the second rod away from the triangular block are pivotally connected to the bottoms of a first slider and a second slider respectively.

[0009] Preferably, the driving component further includes a servo motor mounted on one side of the top of the base, a crank fixed to the output end of the servo motor, a third rod pivotally connected to the other end of the crank, and the other end of the third rod is pivotally connected to the triangular block.

[0010] Preferably, the main body component further includes a mounting head fixed to the bottoms of the chuck and the chuck base, and the chuck and the chuck base are respectively fixed by the mounting head in cooperation with bolts.

[0011] Preferably, a connecting rod is pivotally connected to the triangular block, and each triangular block is pivotally connected to the same connecting rod.

[0012] Preferably, the adjusting mechanism includes a top frame fixed to the bottom of the table board, a bracket hinged to the lower end of the top frame, a bottom frame fixed to the bottom of the bracket, and a first cylinder and a second cylinder pivotally connected to the top of the bottom frame.

[0013] Preferably, the lower ends of the first cylinder and the second cylinder are both pivotally connected to the middle position on one side of the top of the bottom frame, and the output ends of the first cylinder and the second cylinder are respectively pivotally connected to both sides of the lower end of the top frame.

[0014] Beneficial effects

[0015] The utility model provides a die insert inclined hole processing tooling based on an injection mold. Compared with the prior art, the following beneficial effects are achieved:

[0016] (1) By placing the die insert on the chuck base, and then driving the crank by the output end of the servo motor to drive the triangular block to rotate through the third rod, the triangular block drives the first slider and the second slider to move synchronously and reversely along the guide rail through the first rod and the second rod respectively, so that the chuck on the first slider is close to the chuck base on the second slider, thereby fixing the die insert and avoiding the shaking of the die insert when it is inclined subsequently.

[0017] (2) Since each triangular block is pivotally connected to the same connecting rod, when the triangular block rotates, the remaining triangular blocks can be driven to rotate synchronously through the connecting rod, and only one servo motor is needed to control the synchronous use of multiple positioning mechanisms, so as to realize the simultaneous positioning of multiple die inserts.

[0018] (3) By the output end of the first cylinder extending and the output end of the second cylinder contracting, the backward flipping of the top frame is realized; when the output end of the first cylinder contracts and the output end of the second cylinder extends, the forward flipping of the top frame is realized. Thus, by the extension or contraction of the first cylinder and the second cylinder, the inclination angle of the positioning mechanism on the top frame after fixing the die insert can be controlled, and the processing of different inclined holes of the die insert can be realized.

[0028] The driving assembly 22 includes a triangular block 221 rotatably mounted at the bottom of the base 212, a first rod 222 and a second rod 223 pivotally connected to both ends of the triangular block 221 respectively, and the ends of the first rod 222 and the second rod 223 away from the triangular block 221 are respectively pivotally connected to the bottoms of the first slider 214 and the second slider 215. A servo motor 224 is mounted on one side of the top of the base 212, a crank 225 fixed to the output end of the servo motor 224, a third rod 226 pivotally connected to the other end of the crank 225, and the other end of the third rod 226 is pivotally connected to the triangular block 221.

The triangular block 221 drives the first slider 214 and the second slider 215 to move synchronously and reversely along the guide rail 213 through the first rod 222 and the second rod 223 respectively, so that the chuck 216 on the first slider 214 approaches the chuck 217 on the second slider 215, thereby fixing the insert block and preventing the insert block from shaking when it tilts later.

[0030] Specifically, the main body assembly 21 further includes mounting heads 218 fixed to the bottoms of the chuck 216 and the chuck 217, and the chuck 216 and the chuck 217 are respectively fixed by the mounting heads 218 in cooperation with bolts.

[0031] In this embodiment, the chuck 216 and the chuck 217 can be disassembled and assembled from the first slider 214 and the second slider 215 respectively, so as to replace the chuck 216 and the chuck 217 adapted to different specifications of insert blocks.

[0032] Specifically, a connecting rod 3 is pivotally connected to the triangular block 221, and each triangular block 221 is pivotally connected to the same connecting rod 3.

[0033] In this embodiment, when the triangular block 221 rotates, the other triangular blocks 221 can be driven to rotate synchronously through the connecting rod 3, so that only one servo motor 224 can be used to control the synchronous use of multiple positioning mechanisms 2.

Thus, by extending or contracting the first cylinder 14 and the second cylinder 15, the inclination angle of the positioning mechanism 2 on the top frame 11 after the insert block is fixed can be controlled, and machining of different inclined holes of the insert block can be achieved.

[0036] The working principle and usage process of the present utility model are as follows: First, place the insert block on the chuck 217, and then drive the crank 225 through the output end of the servo motor 224 to cooperate with the third support rod 226 to drive the triangular block 221 to rotate.

[0037] Then, when the output end of the first cylinder 14 extends and the output end of the second cylinder 15 contracts, the top frame 11 is turned backward; when the output end of the first cylinder 14 contracts and the output end of the second cylinder 15 extends, the top frame 11 is turned forward. Thus, by extending or contracting the first cylinder 14 and the second cylinder 15, the inclination angle of the positioning mechanism 2 on the top frame 11 after the insert block is fixed can be controlled, and machining of different inclined holes of the insert block can be achieved.
