Description

Technical Field

[0001] The embodiments of the present application relate to but are not limited to the field of injection molding, and in particular to a mold device. Background Art

[0002] The mold device is often used for injection molding of products such as silicone. The mold device usually includes an upper template and a lower template. The lower template is placed on the machine, and the upper template and the lower template are closed by controlling the downward movement of the upper template, thereby realizing product injection molding. However, in actual applications, due to the difference in the matching error accuracy between the machine and the lower template, the forces on various parts of the lower template are uneven during the closing process. When a knife edge is provided in the lower template for waste cutting, the knife edge is often in a suspended state during the closing process. At this time, due to the unevenness of the machine, the knife edge is easily crushed, thereby reducing the service life of the mold device. Therefore, how to extend the service life of the mold device is a technical problem that needs to be solved urgently. Utility Model Content

[0029] Reference Figures 1 to 5 As shown, according to the mold device proposed in the embodiment of the present application, the mold device includes:

[0030] The upper mold plate 100 is provided with a plurality of mold cavities 110 arranged in an array, each mold cavity 110 is provided with a knife edge portion 120 and a supporting platform 130 corresponding to and adjacent to the knife edge portion 120;

[0031] The lower template 200 is provided with a plurality of cores 210 corresponding to the cavities 110 one by one; the cores 210 are provided with a limit platform 220 corresponding to the support platform 130, and the limit platform 220 abuts against the support platform 130 when the upper template 100 and the lower template 200 are closed.

[0032] Therefore, the above-mentioned embodiments of the present application have at least the following beneficial effects: by setting the blade portion 120 on the upper template 100, and setting a support platform 130 adjacent to the blade portion 120 in each cavity 110 in the upper template 100, when the lower template 200 and the upper template 100 are molded, since the limit platform 220 abuts against the support platform 130, at this time, even if the machine is uneven, under the action of the support platform 130, the lower template 200 always maintains a predetermined square shape relative to the blade portion 120 for mold closing, and the lower template 200 will not provide additional pressure in other directions to the blade portion 120, thereby reducing the probability of damage to the blade portion 120. Therefore, compared with the related art, the embodiments of the present application can extend the service life of the mold device.

[0033] It should be noted that the present application does not limit the materials of the upper template 100 and the lower template 200, and those skilled in the art can selectively set them according to actual needs.

[0034] It should be noted that the present application does not limit the structure of the cavity 110 and the core 210 , and those skilled in the art can design the structure of the cavity 110 and the core 210 according to the shape of the molded product.

[0035] It should be noted that the present application does not limit the number of cavities 110 and cores 210 , and does not limit the interval between two adjacent cavities 110 .

[0036] It should be noted that the blade portion 120 is used to cut off the scraps of the molded product to facilitate the removal and demoulding of the molded product.

[0037] It should be noted that the blade portion 120 can be embedded in the cavity 110 by assembly, or can be directly fixed in the cavity 110. In this regard, the embodiment of the present application does not limit the setting method of the blade portion 120, and those skilled in the art can selectively set it according to actual needs. It should be noted that the present application does not impose too many restrictions on the size, size and position of the blade portion 120, and those skilled in the art can selectively set it according to actual needs.

[0038] It should be noted that the embodiment of the present application does not limit the structure of the support platform 130 and the limit platform 220. The size of the support platform 130 and the limit platform 220 can be selectively set according to the actual situation to meet the uneven machine platform and reduce the probability of damage caused by the skew of the blade 120 during mold closing. At this time, since the probability of the skew and breakage of the blade 120 is lower, the yield rate of the molded product is higher.

[0039] In summary, the embodiments of the present application improve the production efficiency and yield of products produced by the mold device, and at the same time can reduce the probability of mold wear caused by machine errors (such as machine balance causing the V-shaped blade of the mold to collapse). Therefore, the product produced by the mold device of the embodiments of the present application has a higher degree of integrity in the waste edge size and can increase the life of the mold device and the stability of the product.

[0040] Understandably, referring to Figure 4 As shown, the blade portion 120 is configured to be V-shaped.

[0041] It should be noted that the V-shaped blade portion 120 can prevent workpieces or waste from accumulating at the orifice, thereby further ensuring the yield rate of the produced products.

[0042] Understandably, referring to Figure 2 As shown, a plurality of molding plates 310 are disposed on the lower template 200 , and the plurality of molding plates 310 are distributed in rows along the length direction of the lower template 200 and in columns along the width direction of the lower template 200 ; each molding plate 310 is provided with a plurality of cores 210 .

[0043] It should be noted that the embodiment of the present application does not limit the number of molding plates 310. In some embodiments, the molding plates 310 can be detachably arranged on the lower mold plate 200 so as to adapt to the molding of different types of products.

[0044] It should be noted that arranging the multiple forming plates 310 in rows and columns can increase the number of forming plates 310 that can be distributed on the lower template 200, and the positions of the formed products are more regular and easier to take out, thereby improving the production efficiency of the products.

[0045] It should be noted that the cores on the forming plate can be of the same shape or of different shapes, and the embodiments of the present application do not limit this. It should be noted that the cores can be arranged at equal intervals or can be selectively arranged according to actual needs.

[0046] For example, Figure 2As shown, six molding plates 310 are arranged on the lower mold plate 200, and the six molding plates 310 are divided into two rows, with three in each row. Fifteen cores 210 are distributed on each molding plate 310, and the 15 cores 210 are divided into three rows, with five in each row; the 15 cores 210 on each molding plate 310 are arranged at equal intervals.

[0047] Understandably, referring to Figure 2 As shown, the outer contour of each molding plate 310 is provided with a first overflow channel 320, and the first overflow channels 320 corresponding to the molding plates 310 in the same column are interconnected, and a groove 311 is opened on the side of each molding plate 310 close to the adjacent molding plates 310 in the same column, and the first overflow channel 320 is provided with a drainage protrusion 312 corresponding to the groove 311 one by one.

[0048] It should be noted that each molding plate 310 is provided with a first overflow channel 320 , so that excess silica gel and the like can overflow into the first overflow channel 320 , thereby improving the yield rate of the product.

[0049] It should be noted that, by providing the groove 311 and the drainage protrusion 312 , the raw materials for molding, such as silicone, can be more quickly and evenly distributed in the first overflow channel 320 when overflowing.

[0050] For example, Figure 2 As shown, the molding plate 310 is set in a square shape, and the first overflow channel 320 is set around the edge of each molding plate 310. For each column of molding plates 310, the molding plates 310 other than the first and last ones are provided with two grooves 311, and each groove 311 is correspondingly provided with a triangular drainage protrusion 312. When the silica gel overflows to the first overflow channel 320 between two adjacent molding plates 310, due to the setting of the groove 311 and the drainage protrusion 312, when there is too much silica gel, part of it can enter the groove 311, so that the excess silica gel can quickly move along the width direction of the molding plate 310, thereby improving the efficiency of product molding.

[0051] Understandably, referring to Figure 2 As shown, the lower mold plate 200 is further provided with a plurality of second overflow channels 330 distributed in parallel, and each second overflow channel 330 is enclosed and arranged along a row of forming plates 310 .

[0052] It should be noted that, by adding the second overflow channel 330 , the overflowing raw materials can be further buffered, thereby improving the yield of the product.

[0053] For example, Figure 2 As shown, the second overflow channel 330 is provided with a square structure, and the second overflow channel 330 and the first overflow channel 320 are adjacently arranged and spaced a certain distance apart.

[0054] Understandably, referring to Figure 2 As shown, the width of the second overflow channel 330 is greater than that of the first overflow channel 320 .

[0055] By setting the width of the second overflow channel 330 to be greater than that of the first overflow channel 320 , buffering of the overflowing raw material can be increased.

[0056] It should be noted that the embodiment of the present application does not limit the specific width values ​​of the first overflow channel 320 and the second overflow width, and those skilled in the art can selectively set them according to actual needs.

[0057] Understandably, referring to Figure 2 and Figure 3 As shown, the upper template 100 and the lower template 200 are both set to be square, the four corners of the upper template 100 are all provided with limiting grooves 140, and the lower template 200 is provided with limiting protrusions 230 corresponding to the limiting grooves 140 one by one.

[0058] It should be noted that, by providing the limiting groove 140 and the limiting protrusion 230 , precise alignment can be achieved, so that the cavity 110 can be molded with the corresponding core 210 .

[0059] It should be noted that, in some embodiments, the height of the limiting protrusion 230 is shallower than the depth of the corresponding limiting groove 140, so as to further improve the convenience of positioning and the accuracy of mold closing.

[0060] Understandably, referring to Figure 3 As shown, one side of the limiting groove 140 is opened.

[0061] It should be noted that by setting an opening on one side of the limit groove 140, the upper end and one side of the limit groove 140 are both open, which facilitates processing and can reduce the initial accuracy requirements for the alignment of the upper template 100 and the lower template 200, thereby improving production efficiency.

[0062] Understandably, referring to Figure 3 As shown, a plurality of buffer grooves 150 are formed on two opposite sides of the upper template 100 .

[0063] It should be noted that by providing a plurality of buffer grooves 150 , the contact area between the upper mold plate 100 and the lower mold plate 200 is reduced, thereby reducing damage to the mold during the mold closing process.

[0064] It should be noted that the embodiment of the present application does not limit the number of buffer slots 150, and those skilled in the art can selectively set them according to actual needs.

[0065] It should be noted that, in some embodiments, the buffer groove 150 is also configured as a groove 311 with one side and one end open.

[0066] For example, refer to Figures 1 to 5 As shown, the mold device of the embodiment of the present application includes an upper mold plate 100 and a lower mold plate 200. The upper mold plate 100 is provided with a plurality of mold cavities 110 arranged in an array, and each mold cavity 110 is provided with a knife edge portion 120 and a support platform 130 corresponding to and adjacent to the knife edge portion 120; the lower mold plate 200 is provided with a plurality of cores 210 corresponding to the mold cavities 110; the cores 210 are provided with a limit platform 220 corresponding to the support platform 130, and the limit platform 220 abuts against the support platform 130 when the upper mold plate 100 and the lower mold plate 200 are molded. Figure 4 As shown, two blade portions 120 are provided in each cavity 110, and two support platforms 130 are also provided in each cavity 110. Accordingly, as shown in FIG. Figure 2 As shown, two limit platforms 220 are also provided on the core 210. Figure 2 Take the lower template 200 in as an example, Figure 2 As shown, two rows of forming plates 310 are arranged on the lower mold plate 200, each row of forming plates 310 is provided with three forming plates 310, each forming plate 310 is provided with 15 cores 210, and the 15 cores 210 are distributed in three rows with equal spacing. Figure 1 and Figure 5 As shown, after placing silica gel in the upper mold 100 and the lower mold 200, the upper mold 100 is pressed down to close the mold, and the silica gel will enter the mold cavity 110 under pressure and be formed under the interaction between the mold cavity 110 and the corresponding core 210. Figure 5 As shown, due to the provision of the support platform 130, when the mold is closed, the limit platform 220 abuts against the support platform 130. At this time, the probability of the blade portion 120 adjacent to the support platform 130 being skewed under force is reduced, thereby improving the yield of the product and the service life of the mold device.
