Technical Field

[0001] The present application relates to the technical field of mold equipment, and in particular to a side hole processing mold. Background Art

[0002] With the continuous development of social economy and the increasing improvement of scientific and technological level, my country's manufacturing industry is also booming. Molds, as various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods, play an important role in the manufacturing industry.

[0003] In the prior art, there is a side hole processing mold, which includes a mold body, and a plurality of hole opening frames are arranged on the mold body, each of which is slidably connected to the mold body, and one end of each of the plurality of hole opening frames extends into the mold cavity of the mold. The mold body is also provided with a plurality of driving members, and the driving members correspond to the hole opening frames one by one, and each driving member is used to drive one end of the corresponding hole opening frame to slide out of the mold cavity. When in use, after the die-casting of the product in the mold cavity of the mold body is completed, each driving member drives the corresponding hole opening frame to slide, and each hole opening frame is completely slid out of the mold cavity of the mold body, thereby releasing the restriction on the product and allowing the product to be smoothly ejected.

[0004] Regarding the above-mentioned related technologies, since the existing technology requires multiple hole opening frames for the production of a single product, and the sliding of each hole opening frame requires a driving component, it is necessary to set multiple driving components on the mold body, and multiple driving components occupy a large space of the mold body, resulting in that only one cavity can be opened on the mold body and only one product is produced, which leads to a decrease in production efficiency, so it needs to be improved. Utility Model Content

[0005] In order to reduce the number of driving components installed on a mold body when driving multiple hole opening frames, the present application provides a side hole processing mold.

[0006] The present application provides a side hole processing die, which adopts the following technical solution:

[0007] A side hole processing mold includes a mold body, the mold body includes an upper mold and a lower mold, the lower mold is provided with a plurality of cavities, and a plurality of hole opening frames are arranged near each of the cavities. One end of each of the hole opening frames is bent and extends into the corresponding cavity. Each of the hole opening frames is slidably connected to the lower mold, and the sliding direction of each of the hole opening frames is inclined to the height direction of the lower mold and forms an acute angle. The other end of each of the hole opening frames extends in a direction away from the cavity and extends out of the lower mold.

[0009] Preferably, the upper mold is further provided with a plurality of positioning blocks, each of which is extended downward and embedded in the top end of the lower mold.

[0011] Preferably, a plurality of embedding grooves for embedding the positioning blocks are provided on the top wall of the lower mold, and the embedding grooves are arranged in a one-to-one correspondence with the positioning blocks.

[0012] By adopting the above technical solution, the setting of the embedding groove can be used for embedding the positioning block, so that the inner wall of the embedding groove fits with the outer wall of the positioning block, reducing the probability of shaking between the upper mold and the lower mold, effectively ensuring the casting effect of the present application and ensuring the accuracy of the product.

[0013] Preferably, a guide column is provided on the bottom end of each positioning block, each guide column is extended downward and inserted into the top end of the lower mold, and a positioning groove for inserting the guide column is also provided on the inner bottom wall of each embedding groove.

[0014] By adopting the above technical solution, the guide column is set so that during the process of closing the upper mold and the lower mold, the guide column can be first inserted into the positioning groove, thereby guiding and positioning the displacement of the positioning block, effectively reducing the wear of the positioning block when it contacts the inner wall of the embedded groove, thereby ensuring the accuracy and service life of the mold of this application.

[0015] Preferably, a guide surface is provided on the bottom end of each guide column.

[0016] By adopting the above technical solution, the setting of the guide surface can make the guide surface on the bottom end of the guide column enter the positioning groove first during the process of closing the upper mold and the lower mold, thereby reducing the wear of the bottom end of the guide column when it first enters the positioning groove and contacts the inner wall of the positioning groove, effectively ensuring the guiding and positioning effect of the guide column.

[0017] Preferably, a plurality of protrusions are provided on the top wall of the lower mold, and each of the protrusions is embedded in the bottom wall of the upper mold.

[0020] By adopting the above technical solution, the installation frame is set up so that when relevant personnel need to drive the sliding of each hole-opening frame, the driving member outside the mold body can push the installation frame to move, so that the installation frame drives the corresponding hole-opening frame to slide along its own sliding direction. At the same time, in this process, the installation frame slides horizontally relative to the driving frame to adapt to the inclined sliding direction of the hole-opening frame.

[0021] Preferably, each of the hole opening frames is provided with a sliding portion on its side wall along its length direction, the sliding portion is slidably connected to the mold body, and a guide surface is also provided at the intersection of the side walls of the sliding portion.

[0022] By adopting the above technical solution, the setting of the sliding part can effectively increase the stability of the hole opening frame when it slides; at the same time, the existence of the sliding part can also effectively reduce the wear between the hole opening frame and the mold body when it slides, thereby reducing the probability of the hole opening frame shaking and ensuring the hole opening effect of the hole opening frame.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Embodiment 1:

[0035] Embodiment 1 of the present application discloses a side hole processing die. Figure 1 and Figure 2 The side hole processing mold includes a mold body 1, and the mold body 1 includes an upper mold 11 and a lower mold 12. In the embodiment of the present application, two cavities 2 are opened on the outer wall of the end of the upper mold 11 and the lower mold 12 close to each other, and they correspond to each other to match the casting product. A plurality of hole opening frames 3 are arranged near the cavity 2 of each lower mold 12, and one end of each hole opening frame 3 is bent and extended into the corresponding cavity 2. Each hole opening frame 3 is slidably connected to the lower mold 12, and the sliding direction of each hole opening frame 3 is inclined to the height direction of the lower mold 12 and forms an acute angle. The other end of each hole opening frame 3 extends in a direction away from the cavity 2 and extends out of the lower mold 12.

[0036] Reference Figure 2 and Figure 3 In the embodiment of the present application, each cavity 2 on the lower mold corresponds to four hole opening frames 3. Each hole opening frame 3 has an end close to the upper mold 11, and is bent toward the cavity 2 to form a hole opening portion 31, and the hole opening portion 31 is integrally formed with the hole opening frame 3.

[0037] Reference Figure 2 and Figure 3 A plurality of opening protrusions 32 are provided on one end of the opening portion 31 close to the corresponding cavity 2. Each opening protrusion 32 is integrally formed with the opening portion 31. Each opening protrusion 32 extends into the cavity 2 so as to form holes on the side wall of the product during casting.

[0038] Reference Figure 2 and Figure 3 The other end of each hole-opening frame 3 extends obliquely downward out of the body of the lower mold 12 and is slidably connected to the lower mold 12. The sliding direction (i.e., the length direction) of each hole-opening frame 3 and the lower mold 12 is inclined to the height direction of the lower mold 12 and forms an acute angle. One end of each hole-opening frame 3 extending out of the lower mold 12 is close to the upper mold 11, so that when the hole-opening frame 3 slides in the direction close to the upper mold 11, different hole-opening portions 31 on the same cavity 2 can be displaced a certain distance in the horizontal direction away from the cavity, so that the plurality of hole-opening portions 31 are separated from each other and out of the holes of the molded product, thereby canceling the locking of the product.

[0039] Reference Figure 2 and Figure 3, sliding parts 33 are provided on opposite side walls of each hole frame 3, and the sliding parts 33 are integrally formed with the corresponding hole frame 3. The extending direction of the sliding parts 33 is the sliding direction of the hole frame 3, and each sliding part 33 is slidably connected to the lower mold 12. Each sliding part 33 is far away from the intersection of the side walls of the main body of the hole frame 3, and an arc-shaped guide surface is provided to reduce the wear between the sliding part 33 and the lower mold 12.

[0040] Reference Figure 2 and Figure 3 , a mounting frame 4 is arranged on one end of each hole frame 33 extending out of the bottom end of the lower mold 12. Each hole frame 3 is fixedly connected to the corresponding mounting frame 4 by bolts, and the end walls of the plurality of mounting frames 4 at one end away from the hole frame 3 are arranged in the same plane. The mounting frame 4 is used to abut against the driving device that drives the hole frame 3 to move, so that it is pushed by the relevant driving device to drive the corresponding hole frame 3 to slide, and the mounting frame 4 can also slide relative to the relevant driving device, and the sliding direction is horizontal to adapt to the inclination angle of the sliding direction of the hole frame 3.

[0041] Reference Figure 2 and Figure 3 , each upper mold 11 is provided with a plurality of positioning blocks 5. In the embodiment of the present application, the number of the positioning blocks 5 is set to four, and the four positioning blocks 5 are respectively arranged at the four corners of the upper mold 11. The top end of each positioning block 5 is integrally formed with the upper mold 11, and the bottom end of each positioning block 5 extends into the top wall of the lower mold 12 and is embedded in the top wall of the lower mold 12. The top wall of the lower mold 12 is also provided with a plurality of embedding grooves 121 for embedding the positioning blocks 5. In the embodiment of the present application, the number of the embedding grooves 121 is set to four, and they are arranged one by one corresponding to the positioning blocks 5.

[0042] The implementation principle of a side hole processing mold in Example 1 of the present application is as follows: after the product is cast, the upper mold 11 is separated from the lower mold 12, and then the relevant driving device pushes each mounting frame 4 to move in the direction close to the upper mold 11. At this time, the hole-opening frame 3 slides obliquely upward along its own sliding direction, thereby driving the corresponding product out of the cavity 2. In this process, the hole-opening protrusion 32 on the hole-opening frame 3 gradually separates from the hole on the product, thereby releasing the lock on the product. In this process, each mounting frame 4 slides relative to the pushed device in the horizontal direction to adapt to the sliding direction of the hole-opening frame 3.

[0043] Embodiment 2:

[0044] The difference between the second embodiment of the present application and the first embodiment is that: Figure 3 and Figure 4A guide column 6 is provided at the bottom end of each positioning block 5 to guide and position the upper mold 11 and the lower mold 12. The guide column 6 is integrally formed with the corresponding positioning block 5, and each guide column 6 extends vertically downward. A guide surface is provided at the bottom end of each guide column 6 to guide the guide column 6 and reduce the wear of the bottom end of the guide column 6.

[0045] Reference Figure 3 and Figure 4 A positioning groove 122 is also formed on the inner bottom wall of each embedding groove 121. The positioning grooves 122 correspond to the guide posts 6 one by one so as to allow the corresponding guide posts 6 to be inserted.

[0046] Reference Figure 3 and Figure 4 , a plurality of protrusions 7 are also provided on the top wall of the lower mold 12. In the embodiment of the present application, the number of protrusions 7 is set to two, and they are respectively located at the two ends of the lower mold 12 along its own length direction. Each protrusion 7 is integrally formed with the lower mold 12, and the top end of each protrusion 7 is extended upward and embedded in the bottom wall of the upper mold 11. Two grooves 111 are also provided on the bottom wall of the upper mold 11, and the grooves 111 correspond to the protrusions 7 one by one and are adapted to each other so that the corresponding protrusions 7 can be embedded.

[0047] The implementation principle of the side hole processing mold in Example 2 of the present application is as follows: when the upper mold 11 and the lower mold 12 are molded together, the upper mold 11 moves downward, and the guide column 6 gradually approaches the inner bottom wall of the embedded groove 121, and is finally inserted into the corresponding positioning groove 122. Then, the positioning block 5 gradually fits with the inner wall of the embedded groove 121, and the protrusion 7 gradually fits with the corresponding groove 111. When the positioning block 5 is completely fitted with the inner wall of the embedded groove 121, the protrusion 7 is completely fitted with the inner wall of the groove 111, and the bottom end of the guide column 6 reaches the bottom end of the positioning groove 122.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
