Embodiment 1

[0029] The embodiment of the present invention provides an injection mold that can finely adjust the glue feeding speed at the gate, such as Figure 1-Figure 6 As shown, it includes a front mold 10 and a back mold 11; the front mold 10 includes a front mold kernel 12; the back mold 11 includes a rear mold kernel 13 corresponding to the front mold kernel 12; the front mold kernel 12 is provided with a plurality of first cavities 180, and a plurality of groups of first sub-runners 181 corresponding to a plurality of first mold cavities 180; the first sub-runners 181 are not communicated with the first cavity 180; Multiple second cavities 182 corresponding to one cavity 180, multiple second runners 183 corresponding to multiple sets of first runners 181, and multiple sets of second runners 183 one-to-one Corresponding multiple gates 184; the gates 184 communicate with the second cavity 182 and the second runner 183;

[0030] The front mold 10 also includes a plurality of buffer ...

Embodiment 2

[0039] The embodiment of the present invention provides an injection mold that can finely adjust the glue feeding speed at the gate. Figure 7 As shown, the receiving slot 188 includes a first sub-slot 1813 located in the middle of the buffer iron block 14, and three groups of second sub-slots 1814 that are evenly distributed around the first sub-slot 1813; the first sub-slot 1813 is circular; The second sub-groove 1814 is a rectangular groove, and communicates with the side walls of the first sub-groove 1813 and the side of the buffer iron block 14; To ensure the accommodation space, after the buffer slot is selected, the fishing rope 16 is re-pressed into the second sub-slot 1814, and the buffer iron block 14 can be smoothly pushed back in the first installation slot 189.

[0040] Such as Figure 7 As shown, the bottom of the first sub-groove 1813 is threadedly connected with the first bolt 111 for winding the fishing rope 16; the first bolt 111 and the buffer iron block 14...

Embodiment 3

[0042] Embodiments of the present invention provide a method for using an injection mold, the method comprising the following steps:

[0043] Step S1: Fix one end of the fishing rope to the electromagnet, and then fix the electromagnet and the front mold core together.

[0044] Step S2: Fix the other end of the fishing rope to the buffer iron block, and turn the buffer iron block to select a designated buffer slot.

[0045] Step S3: After the buffer slot is selected, the buffer iron block is pushed into the first installation slot, the electromagnet is energized, and the buffer iron block is adsorbed, and injection molding production can be carried out.

[0046] Wherein, step S2 includes:

[0047] Step S20: Screw the first bolt into the first sub-slot first, and then wind the fishing rope onto the first bolt.

[0048] Step S21: After the winding is completed, the first bolt is tightened, and the first bolt cooperates with the buffer iron block to clamp the fishing rope, thus...

Abstract

The invention relates to an injection mold capable of finely adjusting the glue feeding speed at pouring gates and a using method. The mold comprises a front mold and a rear mold; the front mold comprises a front mold core; the rear mold comprises a rear mold core; a plurality of first cavities and a plurality of groups of first branch pouring gates are arranged on the front mold core; a pluralityof second cavities, a plurality of groups of second branch pouring gates and a plurality of pouring gates are arranged on the rear mold core; the pouring gates communicate with the second cavities and the second branch pouring gates; the front mold further comprises a plurality of buffer iron blocks and electromagnets; the buffer iron blocks are regular triangular prisms; first buffer grooves, second buffer grooves and third buffer grooves are sequentially formed in the three side surfaces of the buffer iron blocks; the first buffer grooves, the second buffer grooves and the third buffer grooves are different in size; fishing ropes and containing grooves are arranged at the two ends of the buffer iron blocks; the two ends of the fishing ropes are fixed to the electromagnets and the bufferiron blocks correspondingly; a plurality of first mounting grooves and second mounting grooves are formed in the front mold core; and the first mounting grooves are right opposite to the pouring gates. According to the injection mold, the glue feeding speed at the pouring gates can be finely adjusted, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of injection molds, and more specifically relates to an injection mold capable of finely adjusting the glue feeding speed at a gate and a use method thereof. Background technique [0002] Figure 9 It is a common injection molding product. This product is a white transparent part. It is used as the appearance surface of the assembly in the subsequent assembly. In order to ensure the appearance of the product, side gates are often used during injection molding to cover it. Figure 10 , Figure 11 The front mold core and the rear mold core used for injection molding the product are respectively shown, and a structure in which the cavity and the runner are divided into two is adopted; [0003] Specifically, a plurality of first mold cavities 180 are arranged on the front mold core, and a plurality of groups of first sub-runners 181 respectively corresponding to the plurality of first mold cavities 180, the fir...
