Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3: the embodiment discloses a key cap forming die, including support 1 and the template 3 that connects in support 1 in order, template two 4, template three 5, template four 6, template five 7, be equipped with slidable interconnecting piece 11 in the support 1, interconnecting piece 11 is equipped with a plurality of guide bar 12, guide bar 12 passes template one 3, template two 4, template three 5, still connect through guide bar two 41 between the template four 6, template three of template four 6 is connected the face and is equipped with and product assorted lower cavity 61, template two 4, still be equipped with mould benevolence 8 in the template three 5, the tip of going up mould benevolence 8 is equipped with and product assorted upper cavity, upper cavity body coupling lower cavity 61, all be equipped with branch runner 81 in going up mould benevolence 8, branch runner 81 connects a main runner 9.

And a mold opening device is arranged between the third mold plate 5 and the fourth mold plate 6.

Specifically, the mold opening device comprises a pulling plate 73 and a screw 62, one end of the pulling plate 73 is connected to the fifth template 7, the other end of the pulling plate 73 is provided with a waist-shaped hole, and the screw 62 penetrates through the waist-shaped hole to be connected to the fourth template 6. The die sinking device also comprises a third guide rod 71 connected between the fourth die plate 6 and the fifth die plate 7, the third guide rod 71 is also connected with a spring 72, two ends of the spring 72 are respectively connected with the fourth die plate 6 and the fifth die plate 7, and the spring 72 can push the fourth die plate 6 and the fifth die plate 7 open when the die sinking is carried out. Because the four die plates 6 and the five die plates 7 are in a close fit state in the die closing state, and the two ends of the spring 72 are connected with the four die plates 6 and the five die plates 7, a space capable of accommodating the spring 72 needs to be reserved in the four die plates 6 and the five die plates 7, and the method of the embodiment is that the four die plates 6 are provided with pits for connecting the spring 72, and the spring 72 abuts against the bottoms of the pits.

The embodiment further comprises a second main flow channel 91, when the mold is closed, the second main flow channel 91 is connected with the first main flow channel 9, because the first main flow channel 9 moves relative to the fifth template 7 during mold opening, the fifth template 7 is connected with the raw material supply device, and the output end of the raw material supply device is usually a metal hard pipe, so that the second main flow channel 91 is arranged on the fifth template 7 in order to meet the requirement of movement of the first main flow channel 9 during mold opening, when the mold is closed, the end part of the first main flow channel 9 is connected with the end part of the second main flow channel 91, the two main flow channels are equivalent to a pipe, and when the mold is opened, the two main flow channels are separated.

Specifically, the bracket connecting plates 11 of the embodiment have two blocks, and the end of the first guide rod 12 is located between the two bracket connecting plates 11.

This embodiment still includes dog 13, and when the die sinking, the bracket connecting plate 11 moves to the direction of dog 13, and dog 13 is used for withstanding bracket connecting plate 11.

In operation, as shown in fig. 1, in the mold clamping state, the support 1 and the mold plate five 7 are connected to the injection molding machine, and the distance between the two is variable. The lower cavity 61 and the upper cavity (the end of the upper mold core 8) can form a plurality of complete cavities matching the outer contour of the product, and the plurality of cavities are communicated with the corresponding branch flow passages 81. The raw materials enter the cavity through the second main runner 91, the first main runner 9 and the branch runners 81 in sequence. After all cavities are filled and the product is cured, under the action of an injection molding machine, as shown in fig. 2: the distance between the frame 1 and the die plate five 7 increases, and at this time, due to the action of the spring 72, the die plates four 6 and five 7 are separated first in the initial stage of die opening. The positions of the bracket 1, the first template 3, the second template 4, the third template 5, the fourth template 6 and the upper mold core 8 are not changed relatively. As shown in fig. 3: with the continuous increase of the distance between the support 1 and the template five 7, the template two 4, the template three 5 and the template four 6 are also separated, wherein the template two 4 drives the upper die core 8 to be far away from the lower cavity 61, so that the product is demoulded, the product on the upper die core 8 can be pushed off by the motion of the template three 5 relative to the upper die core 8 (the product falls on the upper surface of the template four 6 by virtue of a smaller die drawing angle of the upper die core 8 when moving upwards along with the upper die core 8 in the process of demoulding), and the pushed-off product can fall on a product container by virtue of high-pressure air and the like.

In the process that the third template 5 pushes the product away, the third template 5 is in full contact with the edge of the product, the contact surface is large, and the thrust generated by the third template to the product is along the demoulding direction of the upper mould core 8, so that the product is favorably fallen off, and the product is prevented from deforming.

The utility model discloses can set up a plurality of lower cavitys 61 and go up mould benevolence 8, can once only mould plastics and produce a plurality of products.

The utility model discloses a runner includes two 91 of sprue, sprue 9, branch runner 81, and wherein the relative position between sprue 9, the branch runner 81 does not change to can follow mould benevolence common motion, sprue two 91 is used for switching on raw and other materials and sprue 9.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
