Detailed Description
To achieve the above objects and advantages, and in accordance with the purpose of the invention, as embodied and broadly described herein, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 2, fig. 3, fig. 4, which are a perspective view, a perspective exploded view from another viewing angle, and a side sectional view of the present invention, it can be clearly seen from the figures that the mold 1 of the present invention includes a female mold 11 and a male mold 12, which are combined with each other, wherein the mold 1 is provided with a feeding channel 13 inside the female mold 11, and a sprue 14 is provided at one side of the feeding channel 13, the surface of the mold 1 at one side of the male mold 12 is provided with a sprue 15 which is coaxial with the feeding channel 13 and is communicated with the other side of the feeding channel 13, and the sprue 15 is provided inside with at least one material pulling pin 151 which is perpendicular to the feeding channel 13, and the mold 1 is provided inside with a runner 16 which is communicated with the feeding channel 13 and the sprue 15, and the other side of the runner 16 is communicated with at least one mold cavity 17.
The axial direction of the feeding channel 13 of the die 1 is perpendicular to the axial direction of the branch channel 16 of the die 1.
The pin 151 of the runner 15 may be a cylinder, such as a cylinder, a triangle, a cube, or a rectangular parallelepiped.
However, the above-mentioned pulling pin 151 of the runner 15 is preferably movably inserted or assembled in the runner 15, but in practical applications, it can be integrally formed on the inner wall surface of the runner 15, however, there are many ways to form the pulling pin 151 in the runner 15, so that the structure for achieving the above-mentioned effects should be covered by the present invention, and such simple modifications and equivalent structural changes should be included in the scope of the present invention as well.
Referring to fig. 4, 5, 6, 7, which are a side sectional view, a side sectional view after casting, a schematic diagram of separating a male mold from a female mold after casting, and a three-dimensional appearance of a molded article, it can be seen clearly from the drawings that the female mold 11 and the male mold 12 of the mold 1 are combined with each other, and a raw material (such as a soft material like plastic or rubber) is injected into a runner port 14 of the mold 1 by injection molding, the raw material flows into a runner 15 along a feeding channel 13, the raw material fills the runner 15 and covers a pulling pin 151 inside the runner 15, and after the runner 15 is filled with the raw material, the raw material flows into a runner 16, and then flows into at least one mold cavity 17 of the mold 1 by means of a runner 16, and after the mold cavity 17 is filled with the raw material and cooled, the molded article 2 is formed in the mold 1, and the formed product 2 will be formed into the main stub bar 21, the sub stub bar 22, the branch stub bar 23 and at least one finished product 24 in the feeding channel 13, the pouring gate 15, the branch channel 16 and at least one die cavity 17 of the die 1, respectively, and the through hole 221 for the pulling pin 151 to pass through will be formed in the sub stub bar 22, then the male die 12 of the die 1 can be separated from the female die 11, at this time, because the pulling pin 151 is penetrated inside the sub stub bar 22, and the axial direction of the pulling pin 151 is perpendicular to the axial direction of the feeding channel 13 of the die 1, when the male die 12 is displaced outwards, the pulling pin 151 will lift the pulling force channel of the sub stub bar 22, so that the main stub bar 21 of the formed product 2 can be reliably separated from the feeding channel 13, to avoid the situation that the main stub bar 21 is broken or adhered to the inner side of the feeding channel 13, thus preventing the die 1 from the situation that the process stops due to clamping or stopping, so as to smoothly perform the operation of demoulding and further achieve the effect of improving the manufacturing fluency.
After the male mold 12 of the mold 1 is separated from the female mold 11 and the molded article 2 is completely separated from the female mold 11, the molded article 2 can be taken out of the male mold 12, and at this time, the pulling pin 151 in the through hole 221 of the secondary head 22 is removed, thereby completing the use of the present invention.
Furthermore, the bottom of the female mold 11 of the mold 1 is provided with a plurality of rods 111 inclined outward, the male mold 12 is provided with two sliders 121 capable of moving laterally and relatively, the surface of the two sliders 121 is concavely provided with a plurality of slots 122 inclined outward, when the male mold 12 is combined with the female mold 11, the plurality of rods 111 are inserted into the plurality of slots 122, the plurality of rods 111 are supported against the inner wall surfaces of the plurality of slots 122 to drive the two sliders 121 to move relatively and inwardly, thereby combining the two sliders 121, meanwhile, the two sliders 121 are internally provided with runners 15 and at least one mold cavity 17, when the mold 1 is formed with a formed object 2, the male mold 12 can be separated from the female mold 11, at this time, the plurality of rods 111 are separated from the plurality of slots 122 to cause the two sliders 121 to move relatively and thereby causing the pulling pin 151 to automatically separate from the through hole 221 of the sub-stub 22, thus, the formed product 2 can be taken out of the male die 12 conveniently, and the convenience and the smoothness of the manufacturing operation are improved.
In addition, how to drive the female mold 11 and the male mold 12 of the mold 1 to combine with each other and how to pour the raw material into the gate 14 of the mold 1 is the scope of the prior art, and therefore, a detailed description thereof is omitted for understanding.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
