Detailed Description

The following description of the preferred embodiments of the present invention will be provided with reference to the accompanying drawings, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and the scope of the present invention can be clearly and clearly defined.

The first embodiment is as follows:

the embodiment is an injection mold of an injection molding part with a prefabricated part, and the injection molding part of the prefabricated part is simultaneously injected into the injection molding part by placing the prefabricated part into an injection molding cavity before injecting injection liquid into the mold. However, when the space of the cavity provided with the prefabricated member is small, the prefabricated member is difficult to place, great inconvenience is brought to operation, and time is wasted.

The injection mold of the embodiment is used for injection molding of a prefabricated part and an injection molded part body, as shown in fig. 1-4, the injection mold comprises two connecting plates 1 which are arranged at the outermost side and are opposite to each other, a mold core 2 which is arranged inside the mold, at least one mold cavity 21 for injection molding is arranged in the mold core 2, and a prefabricated part placing rod 3 which can extend into and withdraw from the mold cavity 21, the upper end of the prefabricated part placing rod 3 can extend into the mold cavity 21, the prefabricated part placing rod 3 can synchronously withdraw from a mold main body outwards together with the mold cavity 21 (the direction outwards from the mold main body is the direction indicated by an arrow a in fig. 2), so that when the prefabricated part placing rod 3 withdraws outwards from the mold main body, a prefabricated part sleeve is conveniently placed on the placing rod 3, and is taken into the mold cavity 21 again along with the movement of the prefabricated part placing rod 3, thereby realizing injection molding of the injection molded part with the prefabricated part, effectively shortening the molding cycle, and reducing the processing cost. The utility model discloses a prefab can be the metallics, also can be materials such as high temperature resistant plastics, rubber, silica gel.

The utility model discloses an in some embodiments, still including being arranged in driving the prefab and placing pole 3 and keeping away position unit 4 that withdraws from die cavity 21, keep away position unit 4 and include: the slider 41 that can follow the outside removal of mould main part, the guide block 42 that sets up relatively with slider 41, and the slider 43 with the mutual sliding connection of guide block 42, the utility model discloses a slider 41, guide block 42 and slider 43 set gradually.

A guide slope 411 is provided on the side of the slide block 41 close to the preform placing rod 3, and the guide slope 411 is inclined from the bottom to the top outward along the inside of the mold main body (the terms "up" and "down" as used herein mean "up" close to the top and "down" close to the bottom in the view of fig. 4). Thus, when the slide 41 is moved outwards from the mould body, the preform placement rod 3 can be lowered and correspondingly withdrawn from the cavity 21, so that the preform placement rod 3 can be pushed outwards of the mould body, facilitating the sheathing of the preform. The surface of the guide block 42 on the side close to the slider 41 is inclined in the same direction as the guide slope 411. The slide block 43 is connected to the preform placing rod 3. A guide rail 421 is provided on the side of the guide block 42 close to the slide block 43, and a slide 431 capable of sliding in contact with the guide rail 421 is provided on the slide block 43, and the slide 431 is aligned in the direction in which the preform placing rod 3 is pushed out from the mold main body. Thus, when the slide 41 is pushed out in a direction away from the mold body, the guide block 42 descends by the guide slope 411 and simultaneously carries the slide 43 down, and the preform placing rod 3 is simultaneously withdrawn from the cavity 21 and simultaneously pushed out of the mold body, thereby facilitating the placing of the preform.

In some embodiments of the present invention, a guide sleeve 211 (see fig. 3) for passing air is further provided at one end of the cavity 21 close to the preform placing rod 3.

In some embodiments of the present invention, at least one guiding rod 422 is further disposed on the guiding block 42, and an inclined direction of the guiding rod 422 is consistent with an inclined direction of the guiding inclined plane 411. The utility model discloses still include the deflector 44 (see as shown in fig. 4) of being connected with mould benevolence 2, be provided with the adjustment tank on the deflector 44, guide bar 422 passes the adjustment tank. The direction of the adjustment groove is perpendicular to the direction of pushing the preform placing rod 3 out of the mold body, so that the preform placing rod 3 is surely pushed out while being separated from the cavity 21 by the guiding action of the guide rod 422 in cooperation with the guide block 42 and the slider 41.

The utility model discloses an injection mold of injection molding with prefab still is provided with a plurality of push pins 51 that stretch into in mould benevolence 2 in push pedal 5 including being used for the push pedal 5 of being connected with external drive device, therefore, is used for the injection molding's injection molding drawing of patterns under push pin 51's effect. The utility model discloses still include the die holder 6 with push pedal 5 parallel arrangement, die holder 6 and slider 41 looks butt, push pedal 5 can drive die holder 6 along the A's in figure 2 direction reciprocating motion to can drive slider 41's removal, accomplish from this and place the pole 3 and withdraw from and recover from in the die cavity 21 to the prefab.

In some embodiments of the present invention, at least one buffer spring 7 is further disposed between the push plate 5 and the die holder 6.

Example two:

the embodiment is an injection mold for a headphone sliding arm, which is used for injection molding of the headphone sliding arm 8 shown in fig. 5, and realizes that a bolt 82 is placed in a mounting seat 81 of the arm by injection molding, and is connected with a microphone of an earphone and other structures. As can be seen from fig. 5, the space of the cavity 21 corresponding to the mounting seat 81 is very limited, which is the meaning of the structural design of the present invention, and the operator can conveniently connect the bolt to the preform placing rod 3 by placing the preform placing rod 3 to withdraw from the cavity 21 and push it out from the cavity 21 to the outside of the mold.

In some other possible embodiments of the present invention, the earphone further includes a guide groove located above the cavity 21 and used for communicating two adjacent cavities 21, so that two injection-molded parts of the headset sliding arm connected side by side can be processed.

Example three:

referring again to fig. 5, the present embodiment is a sliding arm of a headphone, which is injection molded by using the injection mold of the first embodiment or the second embodiment.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
