Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a rod forming mold. Background Art

[0002] Molds are various molds and tools used in industrial production to produce the desired products through methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. Specifically, molds usually include an upper mold and a lower mold, each of which has a corresponding shaping area. When the shaping areas are combined, the two shaping areas face each other, shaping the raw materials to produce the corresponding products. However, the existing upper and lower molds are not fixed with limited spacers, resulting in relative displacement between the upper and lower molds during the product cooling and molding process or during transportation. The produced products are distorted and cannot meet production requirements, resulting in a high scrap rate. Utility Model Content

[0003] (1) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the present utility model is to provide a rod forming mold to solve the technical problem that there is no limiting fixation between the existing upper mold and the lower mold, which leads to relative displacement between the upper mold and the lower mold during the product cooling and molding process or the transportation process, resulting in the products produced being distorted and unable to meet production requirements, and the scrap rate is high.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A rod forming die, comprising: an upper die and a lower die corresponding to the upper die, wherein the upper die has a first shaping area formed on one side and a first positioning block extending vertically downward on the other side; the lower die has a second shaping area formed at a position corresponding to the first shaping area, and a first positioning groove is formed inwardly at a position corresponding to the first positioning block to match the shape of the first positioning block and for the first positioning block to be inserted and positioned;

[0008] The present application sets a first positioning block on the upper mold and a first positioning groove on the lower mold. During processing, the raw material is placed in the second molding area, and then the upper mold cover is closed on the lower mold to extrude the raw material. At this time, the first positioning block will be embedded in the first positioning groove. The mutual limitation between the first positioning block and the first positioning groove can prevent displacement between the upper mold and the lower mold, avoid distortion and deformation of the produced products, and meet production requirements.

[0009] Furthermore, one side of the first positioning groove is indented inward to form a second positioning groove, and one side of the first positioning block is extended downward to form a second positioning block that matches the shape of the second positioning groove and can extend into the second positioning groove;

[0010] The second positioning block is inserted into the second positioning groove to directly lock the upper die on the lower die, thereby preventing the upper die from sliding backward relative to the lower die.

[0011] Furthermore, a guiding inclined surface with an arc structure for guiding the second positioning block into the second positioning groove is formed on the transition surface between the first and second positioning grooves;

[0012] The guiding slope can quickly guide the second positioning block to be inserted into the second positioning groove, and no manual precise docking is required when the second positioning block is inserted into the second positioning groove.

[0013] Furthermore, a plurality of anti-slip protrusions are formed on the first positioning groove and abut against the lower end surface of the first positioning block;

[0014] When the mold is used for a long time, wear will occur between the upper mold and the lower mold, and a small gap will be generated between the positioning block and the positioning groove. At this time, a small displacement will occur between the upper mold and the lower mold. The anti-slip protrusions abut against the first positioning block to increase the friction between the two, thereby increasing the friction between the upper mold and the lower mold and avoiding displacement between the upper mold and the lower mold.

[0015] Furthermore, a venting groove communicating with the second positioning groove is provided on the side surface of the lower mold along the length direction of the second positioning groove;

[0016] After the second positioning groove is opened, tiny debris can easily enter the second positioning groove during long-term production operations, causing the upper mold and the lower mold to not cover tightly. After the exhaust groove is opened, when it is necessary to clean the inside of the second positioning groove, air can be blown into the second positioning groove, and the debris will be discharged from the exhaust groove along with the gas, which can ensure the cleanliness of the second positioning groove.

[0026] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0027] The utility model provides a rod forming mold, comprising: an upper mold 1 and a lower mold 2 arranged corresponding to the upper mold 1, wherein a first molding area is formed on one side of the upper mold 1 and the other side extends vertically downward to form a first positioning block 101, and the position of the lower mold 2 corresponding to the first molding area forms a second molding area 202, and the position corresponding to the first positioning block 101 is concave inward to form a first positioning groove 201 that matches the shape of the first positioning block 101 and is used for the first positioning block 101 to be embedded for positioning.

[0028] Specifically, during processing, the raw material is placed on the second molding area 202 of the lower mold 2, and then the upper mold 1 is covered on the lower mold 2 to extrude the raw material. At this time, the first positioning block 101 will be embedded in the first positioning groove 201. The mutual limitation between the first positioning block 101 and the first positioning groove 201 can prevent displacement between the upper mold 1 and the lower mold 2 during the cooling and molding process of the product, avoid deformation of the product, and ensure the yield of the product.

[0029] Specifically, after the first positioning block 101 is embedded in the first positioning groove 201 , it can prevent the upper mold 1 from moving leftward, rightward, and forward relative to the lower mold 2 .

[0030] In the first preferred embodiment, a second positioning groove 203 can be set on one side of the first positioning groove 201. The first positioning groove 201 and the second positioning groove 203 are connected to each other and form a right-angle structure. In addition, a second positioning block 102 is extended downwardly from the position corresponding to the second positioning groove 203 on one side of the first positioning block 101. The second positioning block 102 matches the second positioning groove 203 in shape and size. The first positioning block 101 and the second positioning block 102 are connected into one body to form a right-angle structure. When the second positioning block 102 is inserted into the second positioning groove 203, the upper mold 1 can be directly locked into the lower mold 2 to prevent the upper mold 1 from moving backward relative to the lower mold 2.

[0031] Specifically, the right-angle structure formed by the first positioning groove 201 and the second positioning groove 203 is equivalent to providing a boss structure between the first positioning groove 201 and the second positioning groove 203. Furthermore, an arc-shaped guiding slope 204 can be provided at the transition surface between the first positioning groove 201 and the second positioning groove 203, i.e., at the edge of the boss. When the second positioning block 102 contacts the guiding slope 204, the guiding slope 204 can quickly guide the second positioning block 102 into the second positioning groove 203.

[0032] In the second preferred embodiment, a plurality of anti-slip protrusions 205 can be provided on the first positioning groove 201. The anti-slip protrusions 205 can be made of soft rubber material. When the first positioning block 101 and the second positioning block 102 are inserted into the first positioning groove 201 and the second positioning groove 203, the lower end face of the first positioning block 101 contacts the anti-slip protrusions 205, thereby increasing the friction between the upper mold 1 and the lower mold 2, and preventing the mold from being worn and gapped between the positioning block and the positioning groove due to long-term use. During the processing, a slight displacement will occur between the upper mold 1 and the lower mold 2.

[0033] Furthermore, an exhaust groove 206 can be provided on the side of the lower mold 2 along the length of the second positioning groove 203, and the exhaust groove 206 is connected to the second positioning groove 203. When the interior of the second positioning groove 203 needs to be cleaned, air can be blown into the second positioning groove 203, and the air and debris will be discharged from the exhaust groove 206, thereby ensuring the cleanliness of the second positioning groove 203.

[0034] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
