Detailed Description
A preferred scheme is as shown in fig. 1 to 4, a detachable die device for manufacturing a voice coil motor frame comprises a die 1, wherein the die 1 is used for forming the frame through hot press forming, a plurality of pins 2 are arranged at the bottom of the die 1, and the die 1 is inserted and installed on the upper surface of a middle layer plate 3 through the pins 2; the middle layer plate 3 is provided with pin holes at the joint of the middle layer plate 3 and the pins 2; a bottom plate 4 is arranged below the middle layer plate 3, the bottom plate 4 is detachably connected with the middle layer plate 3, and a gap is formed between the bottom plate 4 and the middle layer plate 3;
the middle layer plate 3, the bottom plate 4 and the contact pins 2 are made of 5CrMnMo steel which is hot-work die steel and is commonly used in a hot forming die; the voice coil motor is generally small in size, the frame of the voice coil motor is made of thin steel through hot press molding, the local temperature of the mold 1 is 200-300 ℃, and the environmental temperature is lower than 200 ℃.
Furthermore, the upper surface of the bottom plate 4 is provided with a hole, and the front end of the contact pin 2 is inserted into the hole.
Further, a buffer block 5 is arranged between the die 1 and the middle layer plate 3, and the buffer block 5 is fixed on the middle layer plate 3; the buffer block 5 is made of perfluoro ether fire-resistant rubber which can resist the high temperature below 300 ℃; because the die 1 is extruded by the stamping part, in order to prevent the die 1 and the middle layer plate 3 from generating large mechanical friction, the buffer block 5 can effectively prevent mechanical abrasion.
Furthermore, the buffer block 5 is of a multi-edge structure, and the number of the pins 2 is double the number of the edges of the buffer block 5; two edges of each edge of each corner of the buffer block 5 are provided with contact pins 2, and the contact pins 2 are attached to the edges of the corners of the buffer block 5; the design of the contact pin 2 can improve the detachability of the device, but the strength of the contact pin 2 is relatively brittle, and the contact pin 2 is tightly attached to the buffer block 5, so that the contact pin 2 can be prevented from being deformed due to torsion generated by the mold 1;
in this technical scheme, buffer block 5 is equipped with four bellied edges and corners, and the contact pin quantity of mould bottom is eight.
Further, a buffer block placing groove is formed in the middle layer plate 3 at the joint of the buffer block 5 and the middle layer plate 3; the size of buffer block 5 slightly is greater than the buffer block standing groove, and when buffer block 5 was placed in the buffer block standing groove like this, buffer block 5 was difficult for dropping.
Furthermore, a plurality of dies 1 are arranged on the upper surface of the middle layer plate 3, and the dies 1 are arranged on the upper surface of the middle layer plate 3 in a rectangular shape.
Further, the bottom plate 4 is connected with the middle plate 3 through a support bolt 6, and a screw of the support bolt 6 consists of a thread section 601 and a polished rod section 602; the threaded section 601 is positioned at the front end of the polished rod section 602, and the diameter of the threaded section 601 is smaller than that of the polished rod section 602; the thread section 601 is connected with the middle layer plate 3 through threads, and the polished rod section 602 penetrates through the bottom plate 4.
Furthermore, mounting holes 7 are formed in the two edges of the middle layer plate 3 and the bottom plate 4, and mounting holes 7 are formed in the side face of the bottom plate 4; the mounting hole 7 is used for fixing the device on a stamping platform.
The structural principle of the whole device is as follows:
the bottom of the mold 1 is designed into a structure of a pin 2, the mold 1 is inserted into the middle layer plate 3 for use, the mold 1 can be replaced at any time, and when the mold 1 is damaged, the mold 1 can be replaced independently; the buffer block 5 can reduce the mechanical damage between the die 1 and the middle layer plate 3;
in order to ensure that the pin 2 has good stability, the pin 2 needs to be ensured to have a certain length, but if the pin 2 is too long, the width of the middle layer plate 3 needs to be correspondingly widened, which causes material waste; the middle layer plate 3 and the bottom plate 4 are separately designed, so that firstly, the requirement on the width of the whole device can be met, and meanwhile, materials can be saved; secondly, the heat dissipation of the device, especially the heat dissipation effect at the pins 2, can be improved.
