The female die comprises a first color female die 11 and a second color female die 12 which are arranged side by side, a first cavity 111 used for accommodating a sliding block with a self-locking function is arranged on the first color female die 11, and a second cavity 121 used for accommodating a sliding block with a self-locking function is arranged on the second color female die 12, so that the first cavity 111 and the second cavity 121 are both in profile modeling with the sliding block with the self-locking function. The public mould is including the public mould of the first colour and the public mould of second colour that set up side by side, and the public mould of first colour is including the first core 21 that is used for shaping first colour product, and the public mould of second colour is including the second core 22 that is used for shaping second colour product, is equipped with at least one slider that has self-locking function on first core 21 and the second core 22 respectively, and generally speaking, the first core 21 of first colour public mould is the same with the structure of the second core 22 of the public mould of second colour, and consequently, the structure and the distribution position of the slider that has self-locking function on first core 21 and the second core 22 are also the same.
As shown in fig. 2 and 3, the slider with the self-locking function of the present embodiment includes:
and a mounting portion 31 embedded in the first core 21 or the second core 22, wherein the mounting portion 31 is slidably connected to the first core 21 and the second core 22. That is, the slider having the self-locking function on the first core 21 is slidably connected to the first core 21 through the mounting portion 31, and the slider having the self-locking function on the second core 22 is slidably connected to the second core 22 through the mounting portion 31.
And a molding part 32 disposed on one side of the mounting part 31 facing the first cavity 111 or the second cavity 121 and located at one end of the mounting part 31. The molding portion 32 is used for molding a first color product when the female mold and the male mold are closed, and the first color product in this embodiment refers to a product molded by matching the first color female mold 11 and the first color male mold, or a product molded by matching the first color female mold 11 and the second color male mold. Specifically, when the female mold and the male mold are closed, the molding portion 32 of the slider having the self-locking function corresponding to the first color female mold 11 (located below the first color female mold 11) extends into the first color female mold 11 to mold a first color product; the molding portion 32 of the slider having the self-locking function corresponding to the second color master 12 (located below the second color master 12) is not separated from the first color product, and thus, extends into the second color master 12 together with the first color product to mold the second color product.
And a self-locking portion 33 provided on the side of the mounting portion 31 having the molding portion 32 and at the other end of the mounting portion 31. The self-locking part 33 comprises a first inclined wall 331 and a second inclined wall 332 which are oppositely arranged, the first inclined wall 331 is located on one side of the self-locking part 33 close to the forming part 32, the second inclined wall 332 is located on one side of the self-locking part 33 away from the forming part 32, and the distance between the first inclined wall 331 and the second inclined wall 332 is reduced along the direction from the male die to the female die, or the first inclined wall 331 and the second inclined wall 332 are inclined towards each other along the direction from the male die to the female die.
By adopting the scheme, the movement mode of the sliding block with the self-locking function in the embodiment in work is as follows:
when the male mold and the female mold are closed, the second inclined wall 332 of the self-locking portion 33 corresponding to the first cavity 111 is abutted by the inner wall of the first cavity 111, so that the slide block with the self-locking function is reset, or in other words, when the first color product is molded, under the action of the inner wall (such as the first side wall 1111 in the figure) of the first cavity 111, the self-locking portion 33 and the molding portion 32 corresponding to the first cavity 111 can slide into the first cavity 111 to be matched with the corresponding core, so that the first color product can be molded.
When the male mold and the female mold are closed, the first inclined wall 331 of the self-locking portion 33 corresponding to the second cavity 121 is pressed and pushed by an inner wall (e.g., the second side wall 1211 in the figure) of the second cavity 121, so that the slider with the self-locking function is separated from the first color product to realize core pulling.
By means of the above situation, the slider with the self-locking function of the embodiment is provided with the self-locking part 33, and the self-locking part 33 is provided with the first inclined wall 331 and the second inclined wall 332 which are opposite to each other, when the male mold and the female mold are closed, the inner wall of the first cavity 111 abuts against the second inclined wall 332 to reset the slider, and the inner wall of the second cavity 121 pushes the first inclined wall 331 to loose the core of the slider, so that the space of the mold can be greatly saved, the material cost can be saved, meanwhile, the slider can be automatically reset after the core is pulled, the manual reset is saved, and the production efficiency is improved.
Specifically, the slider with the self-locking function of the embodiment has a simple structure and a small volume, so that the slider can be integrally processed and formed (for example, machined) without being assembled in a welding or detachable connection mode, and the precision of the structure is ensured. In order to ensure the molding quality of the product, the molding portion 32 may be made of the same material as the first core 21 and the second core 22, and thus, the mounting portion 31 and the self-locking portion 33 may be made of the same material as the first core 21 and/or the second core 22. Specifically, the mounting portion 31, the forming portion 32, and the self-locking portion 33 of the present embodiment may be made of heat-treated die steel, for example, SKD61 steel or 8407 steel.
Specifically, as shown in fig. 2 and 3, the slider with the self-locking function of the present embodiment further includes a guide block 4 connected to the mounting portion 31, and further, the first core 21 and/or the second core 22 are further provided with a guide rail 221 for cooperating with the guide block 4. The cooperation of the guide block 4 and the guide rail 221 can guide the slider having the self-locking function when the slider having the self-locking function slides with respect to the first core 21 or the second core 22. In this way, the friction between the guide block 4 and the guide rail 221 is adopted instead of the friction between the mounting portion 31 and the core, and the guide block 4 and the guide rail 221 can be made of steel materials with lower cost, thereby further saving material cost.
The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
