Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a simple and applicable mold inclined top structure. Background Art

[0002] An injection mold is a mold used to produce plastic products. The molten plastic is injected into the mold through an injection molding machine, and the desired plastic product is formed after cooling. The injection mold is usually composed of an upper mold, a lower mold and a mold core. It can be designed and manufactured according to the shape and size of the product. Injection molds are widely used in automotive parts, home appliances, daily necessities, medical equipment and other fields. It is an indispensable and important tool in the production process of plastic products. With the development of science and technology, the manufacturing technology of injection molds is also constantly improving to meet the ever-changing market needs.

[0003] At present, in the processing of some products, it is necessary to use a tilting rod to form a buckle on the product. For example, the Chinese patent announcement number "CN104526991A" discloses an injection mold tilting structure, which includes a B plate and a lower bottom plate arranged up and down, and a tilting mechanism arranged thereon, and a vertically arranged tilting guide block is arranged between the B plate and the lower bottom plate, and a slide groove for the tilting guide to move through is provided on the tilting guide block, and the tilting top and the tilting top seat that constitute the tilting top mechanism form a sliding guide cooperation in the horizontal direction.

[0004] Due to the space limitations of some products, it is easy for the conventional inclined top design of the product buckle position to fail to meet the production requirements. The reason is that the conventional inclined top structure occupies too much space and has poor adaptation effect on thin-walled products. Based on this, in order to further optimize the applicability of existing molds, we propose a simple and applicable mold inclined top structure. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3 This is an embodiment of the utility model, which discloses a simple and applicable mold inclined top structure, which is used to solve the problem that some products are currently limited by space and the conventional inclined top design of the product buckle position cannot meet the production needs. Specifically, the inclined top structure described in this embodiment includes:

[0024] An upper mold core 1 having an injection flow channel 11, and a lower mold core 2 having a molding cavity 21:

[0025] Specifically, the upper mold core 1 is connected to the upper mold base and moves with it, the lower mold core 2 is connected to the lower mold base, and the injection port on the upper mold base is connected to the injection runner 11 to transport the injection material to between the upper mold core 1 and the lower mold core 2 to achieve the molding of the product 5. This connection method is a conventional means for technicians in the relevant field and will not be elaborated here.

[0026] A through groove is provided in the middle of the upper mold core 1, a fixing seat 12 is fixed in the through groove, a plurality of channels 13 are obliquely distributed inside the fixing seat 12, a push rod 14 is slidably connected in the channel 13, it should be noted that in the present embodiment, the injection flow channel 11 is arranged on the fixing seat 12 to realize convenient injection molding, wherein the fixing seat 12 can move independently relative to the upper mold core 1, so as to realize the driving of the push rod 14, and the independent driving mode can adopt a conventional spring telescopic rod structure to ensure that there is an independent movement space between the fixing seat 12 and the upper mold core 1;

[0027] A guide assembly 3 for guiding the ejector rod 14 is further provided on the upper mold core 1 , and a molding die 22 is provided in the molding cavity 21 .

[0028] In some embodiments, the top rod 14 in the utility model includes an inclined rod portion 141 and a cross rod portion 142, and a buckle molding groove 143 is provided on the free end of the cross rod portion 142. During actual injection molding, the buckle molding groove 143 at the end of the cross rod portion 142 is used to injection mold the buckle of the product 5, and cooperates with the molding mold 22 to complete the injection molding operation of the entire product.

[0029] Furthermore, in this embodiment, the guide assembly 3 includes a limit plate 31 fixed on the upper die core 1, a transverse groove 32 is provided on the end surface of the ejector rod 14, and at least a portion of the limit plate 31 is inserted into the interior of the transverse groove 32;

When the injection molding is completed, the upper mold seat will drive the fixing seat 12 to move upward. Since it is stopped by the limiting plate 31, the push rod 14 cannot move upward. After further movement, under the influence of the channel 13, the push rod 14 is driven to start to move horizontally until it is separated from the buckle position of the product 5. At this time, the upper mold core 1 can be separated from the lower mold core 2 to achieve the taking of the product.

[0031] On the basis of the above-mentioned embodiments, the upper mold core 1 in this embodiment is provided with an installation slot 15, the limiting plate 31 is placed in the installation slot 15 and fixed by a locking member.

After injection molding, the upper mold core 1 and the lower mold core 2 can be cooled by connecting to circulating cooling water, thereby improving the cooling efficiency of the product 5.

[0034] In summary, the utility model adopts a structural design of setting the push rod 14 in the upper mold core 1, and utilizes its own space to arrange the push rod 14, so that the moving space of the push rod 14 is completely in the upper mold core 1, which can effectively save the space occupied by the push rod 14 and improve the applicability of injection molding of the product 5. In addition, the guiding limit of the push rod 14 is realized by the limit plate 31. At the same time, since the limit plate 31 is detachably connected, the convenience of disassembly and maintenance of the push rod 14 can also be improved. The structural design is simple, so that the mold meets the production needs.
