Description

Technical Field

[0001] This utility model belongs to the technical field of DIP misaligned pin forming mold, specifically relating to a DIP misaligned pin forming mold. Background Technology

[0002] DIP misaligned pin forming mold is a mold used to produce dual in-line package electronic components. It is mainly used to misalign the pins during the forming process to ensure that the pins are correctly aligned when inserted into the circuit board. Through precise design and manufacturing, the mold can effectively control the shape and position of the pins, avoid poor soldering or component damage caused by pin misalignment, thereby improving production efficiency and product quality.

[0003] When using DIP misaligned pin forming molds, the male and female templates are fixed together by a fixing device. However, the fixing device makes the male and female templates fit too tightly. The tight fit will increase the friction between the molds, leading to increased wear and shortening the service life of the mold. Utility Model Content

[0004] The purpose of this utility model is to provide a DIP misaligned pin forming mold to solve the problem mentioned in the background art that when the male and female templates of the DIP misaligned pin forming mold are used, the fixing device makes the male and female templates too tightly fit together. The excessively tight fit will increase the friction between the molds, leading to increased wear and shortening the service life of the mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a DIP misaligned pin forming mold, comprising an upper fixing plate, a female template installed at the lower end of the upper fixing plate, a male template installed at the lower end of the female template, upper fixing blocks fixed at the left and right ends of the female template, lower fixing blocks fixed at the left and right ends of the male template, an insertion block fitted inside the upper fixing block being inserted into the lower fixing block, push plates fixedly extending from the upper left and right ends of the insertion block, a stainless steel spring fixedly at the lower end of the push plates, a threaded hole provided inside the insertion block, a bolt inserted inside the lower fixing block entering the threaded hole, and a rotating shaft fixedly at the outer wall of the bolt.

[0006] Preferably, pin injection grooves are provided inside the female template and the male template.

[0007] Preferably, a support plate is installed at the lower end of the template, and partitions are provided at the lower ends of the support plate on the left and right sides.

[0008] Preferably, a lower fixing plate is installed at the lower end of the partition, and a disassembly plate is installed at the middle of the upper end of the lower fixing plate.

[0009] Preferably, the upper end of the unloading plate is equipped with a locking mechanism located on the left and right sides.

[0010] Preferably, the upper fixing block inserts the insertion block into the slot located at the upper end of the lower fixing block, and the bolt column rotates about the rotation axis at its internal position in the lower fixing block.

[0011] Preferably, the rotation of the bolt causes the insert block to move downward, and the movement of the insert block causes the push plate to compress the stainless steel spring.

[0012] Preferably, the movement of the push plate causes the upper fixing block and the lower fixing block to fit tightly together.

[0013] Compared with the prior art, this utility model provides a DIP misaligned pin forming mold, which has the following beneficial effects:

[0014] This device has upper and lower fixing blocks fixed at the left and right ends of the female and male templates. When the female and male templates are fitted together, the insert block in the upper fixing block is inserted into the groove of the lower fixing block. At the same time, the bolt is manually rotated to enter the internal position of the threaded hole. The bolt rotates in the internal position of the threaded hole, causing the insert block to move downward. The movement of the insert block causes the push plate to compress the stainless steel spring. When the stainless steel spring is fully compressed, it indicates that the upper and lower fixing blocks are in the tightest fit. When using the device, the operator can stop rotating once the bolt is fitted with the upper and lower fixing blocks. In this way, the elastic force of the stainless steel spring allows for a small vertical movement space between the male and female templates, which can effectively reduce friction between the male and female templates and reduce wear.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] The utility model provides, for example Figure 1-4 The DIP misaligned pin forming mold shown includes an upper fixing plate 1, a female template 2 installed at the lower end of the upper fixing plate 1, a male template 3 installed at the lower end of the female template 2, upper fixing blocks 11 fixed at the left and right ends of the female template 2, lower fixing blocks 10 fixed at the left and right ends of the male template 3, an insertion block 13 fitted inside the upper fixing block 11 and inserted into the lower fixing block 10, push plates 16 fixed at the upper ends of the left and right ends of the insertion block 13, a stainless steel spring 15 fixed at the lower end of the push plate 16, a threaded hole 17 provided inside the insertion block 13, a bolt post 9 fitted inside the lower fixing block 10 and inserted into the threaded hole 17, and a rotating shaft 14 fixed at the outer wall of the bolt post 9.

[0022] Before injection molding, confirm that the female mold plate 2 and male mold plate 3 are correctly installed and ensure the alignment of the upper and lower structures of the mold. After the plastic raw material is melted in the heating device, it is injected into the mold through the injection system. The molten plastic flows into the pin injection groove 12 and fills the cavity of the DIP element. Due to the staggered pins in the design, the mold has appropriate cavities and pin grooves to ensure that the plastic can evenly fill the entire cavity. After injection molding, the mold will be kept for a certain period of time to allow the molten plastic to solidify and form the final product.

[0023] like Figure 3 and Figure 4As shown, pin injection grooves 12 are provided inside the female template 2 and male template 3. A support plate 4 is installed at the lower end of the male template 3. A partition plate 5 is provided at the lower end of the support plate 4 on the left and right sides. A lower fixing plate 8 is installed at the lower end of the partition plate 5. A removal plate 7 is installed at the middle of the upper end of the lower fixing plate 8. A return lock 6 is installed at the upper end of the removal plate 7 on the left and right sides. The upper fixing block 11 inserts the insertion block 13 into the slot located at the upper end of the lower fixing block 10. The bolt column 9 rotates around the rotating shaft 14 at the internal position of the lower fixing block 10. The rotation of the bolt column 9 causes the insertion block 13 to move downward. The movement of the insertion block 13 causes the push plate 16 to compress the stainless steel spring 15. The movement of the push plate 16 makes the upper fixing block 11 and the lower fixing block 10 fit tightly together.

[0024] Insert the insertion block 13 in the upper fixing block 11 into the groove of the lower fixing block 10, and at the same time manually rotate the bolt post 9 so that it enters the internal position of the threaded hole 17. The bolt post 9 rotates in the internal position of the threaded hole 17, causing the insertion block 13 to move downward. The movement of the insertion block 13 causes the push plate 16 to compress the stainless steel spring 15. When the stainless steel spring 15 is fully compressed, it means that the upper fixing block 11 and the lower fixing block 10 are in the tightest fit. When using it, the operator can stop rotating after the bolt post 9 is in contact with the upper fixing block 11 and the lower fixing block 10. In this way, through the elastic force of the stainless steel spring 15, a little space can be reserved between the male template 3 and the female template 2 for vertical movement, thereby effectively reducing the friction between the male template 3 and the female template 2.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
