Description

Technical Field

[0001] This utility model relates to the field of pre-embedded injection molding technology, and in particular to a stud installation tool and injection mold. Background Technology

[0002] Injection-molded copper busbars are integrated components formed by integrally molding copper busbars and insulating plastic. During their manufacturing process, studs are often embedded to facilitate the mounting of electronic components with screws. Currently, stud embedding typically employs a pre-embedded injection molding process. This involves first pre-positioning the stud as an insert on the locating pins of the mold, then closing the mold and injecting the molten plastic to encapsulate both the copper busbar and the stud, thus forming the injection-molded copper busbar. To prevent burns from the high temperature of the mold, existing technologies typically use stud installation tools to install the metal stud onto the locating pins within the stud embedding grooves of the mold.

[0003] Chinese patent application CN209304876U discloses an auxiliary tool for inserting plastic nuts, including an input tube and a nut storage cylinder disposed at the top of the input tube and connected to it. A stirring rod is installed inside the nut storage cylinder, and a square sleeve connected to the side wall of the input tube is disposed thereto. A movable baffle that can slide radially along the input tube is installed inside the square sleeve. In use, the nut is first added to the nut storage cylinder, then the stirring rod is agitated to allow the nut to enter the input tube. Next, the bottom end of the input tube is inserted into the stud embedding groove of the mold, and the movable baffle is pulled to allow the nut to fall freely and be fitted onto the positioning pin, thus completing the nut embedding installation. However, the aforementioned tools rely on gravity to install the studs onto the positioning pins, and are only suitable for vertical installation of studs. But when the injection-molded copper busbar structure cannot reserve space for vertical installation of studs, or when the injection-molded copper busbar requires studs to provide lateral connection interfaces, the studs need to be arranged horizontally. Since the direction of gravity is perpendicular to the installation direction of the studs, the aforementioned tools cannot install horizontal studs. The installation of horizontal studs can only rely on manual labor, which not only poses a risk of burns but also reduces production efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing stud installation tools are only suitable for vertical installation of studs and cannot install horizontal studs.

[0014] This utility model provides an injection mold for use with a stud installation fixture. The injection mold includes a mold body, on which a stud insertion groove for installing a stud and a positioning pin disposed in the stud insertion groove are provided. The positioning pin extends along the installation direction of the stud, and one end of the positioning pin is fixed to the side wall inside the stud insertion groove. The stud has a mounting through hole. The front end of the sleeve is inserted into the stud's embedded groove. The push rod is moved to push the stud's mounting through hole onto the positioning pin.

[0015] Compared with the prior art, the advantages of this utility model embodiment of a stud installation tooling and injection mold are as follows: This utility model discloses a stud installation fixture and injection mold, comprising a sleeve and a push rod slidably inserted into the installation channel of the sleeve, with the stud inserted into the installation channel at the front end of the push rod. In use, the stud is first fixed in the installation channel, then the sleeve is inserted into the stud embedding groove of the injection mold to guide the sliding of the stud, aligning the stud's installation through hole with the positioning pin in the stud embedding groove. The push rod is then pushed to mount the stud onto the positioning pin; continued pushing of the push rod installs the stud into place. This utility model's stud installation relies on the push of the push rod, enabling stud installation at different angles. It solves the problem that existing stud installation tools are only suitable for vertical stud installation and cannot install horizontal studs, which requires manual installation, posing a risk of burns and reducing production efficiency.

[0016] Furthermore, the push rod is provided with a first stop and a second stop arranged at intervals along its length. A groove is formed between the first stop, the second stop, and the push rod. A positioning element is located at the rear end of the sleeve, with one edge extending into the groove. In use, the push rod slides relative to the sleeve, the positioning element slides in the groove, and the first stop abuts against the positioning element, preventing the push rod from sliding backward and avoiding it from detaching from the sleeve. Since the sleeve is inserted into the groove when installing the stud, it is difficult to determine whether the stud has detached from the stud installation fixture after installation, and to avoid taking the stud out when removing the sleeve. In this embodiment, when the second stop abuts against the positioning element, the push rod completely pushes the stud out of the installation channel, realizing the detachment of the stud from the stud installation fixture. That is, when the second stop abuts against the positioning element, it can be determined that the stud has detached from the stud installation fixture, helping workers to confirm the installation status of the stud and avoiding taking the stud out when removing the sleeve.

[0017] The present invention has a simple structure and is easy to operate. It solves the technical problem that the existing stud installation tools are only suitable for vertical installation of studs and cannot install horizontal studs. The installation of horizontal studs can only rely on manual labor, which not only poses a risk of burns but also reduces production efficiency. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "vertical", "horizontal", "bottom", "inner", "outer" and other terms used in this utility model to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 9 As shown, a preferred embodiment of the present invention provides a stud installation fixture, comprising a sleeve 1, a push rod 2, and a positioning element 5. The sleeve 1 has an open front end. The outer periphery of the push rod 2 is provided with a first stop 3 and a second stop 4 arranged at intervals along the length direction of the push rod 2. The first stop 3, the second stop 4, and the push rod 2 form a sliding groove. The positioning element 5 is connected to the rear end of the sleeve 1. The front side of the push rod 2 is slidably inserted into an installation channel within the sleeve 1. The installation channel within the sleeve 1 is formed by the internal space of the sleeve 1, and one edge of the positioning element 5 extends into the sliding groove. The installation channel at the front end of the push rod 2 is used for inserting the stud 10. The push rod 2 is used to slide along the front end of the installation channel to push at least a portion of the stud 10 to move outside the installation channel.

[0025] The stud installation fixture of this utility model includes a sleeve 1 and a push rod 2 that slides into the installation channel of the sleeve 1. The stud 10 is inserted into the installation channel at the front end of the push rod 2. In use, the stud 10 is first inserted and fixed in the installation channel. Then, the sleeve 1 is inserted into the stud embedding groove 91 of the injection mold to guide the sliding of the stud 10, aligning the installation through hole of the stud 10 with the positioning pin 92 in the stud embedding groove 91. Then, the push rod 2 is pushed to mount the stud 10 onto the positioning pin 92. Continuing to push the push rod 2 will install the stud 10 into place. The installation of the stud 10 in this utility model relies on the pushing of the push rod 2, enabling the installation of studs 10 at different angles. This solves the technical problem that existing stud installation tools are only suitable for vertical installation of studs and cannot install horizontal studs. Horizontal stud installation relies on manual labor, which not only poses a risk of burns but also reduces production efficiency.

[0026] Furthermore, the push rod 2 is provided with a first stop 3 and a second stop 4 arranged at intervals along its length direction. A sliding groove is formed between the first stop 3, the second stop 4 and the push rod 2. The positioning member 5 is provided at the rear end of the sleeve 1, and one side edge of the member extends into the sliding groove. In use, the push rod 2 slides relative to the sleeve 1, the positioning element 5 slides in the groove, and the first stop 3 abuts against the positioning element 5, which can stop the push rod 2 from sliding backward and prevent the push rod 2 from disengaging from the sleeve 1. Since the sleeve 1 is inserted into the stud embedding groove 91 when the stud 10 is installed, it is difficult to determine whether the stud 10 is disengaged from the stud installation fixture. In order to avoid the stud 10 being pulled out when the sleeve 1 is withdrawn, in this embodiment of the present invention, when the second stop 4 abuts against the positioning element 5, the push rod 2 completely pushes the stud 10 out of the installation channel, realizing the disengagement of the stud 10 from the stud installation fixture. That is, when the second stop 4 abuts against the positioning element 5, it can be determined that the stud 10 is disengaged from the stud installation fixture, which helps the worker to confirm the installation status of the stud 10 and avoids the stud 10 being pulled out when the sleeve 1 is withdrawn.

[0027] Furthermore, such as Figures 1 to 4 As shown, the sleeve 1 includes a first pipe section 11 and a second pipe section 12 connected in sequence. The installation channel is set in the first pipe section 11 and the second pipe section 12. In this embodiment of the utility model, the internal spaces of the first pipe section 11 and the second pipe section 12 together form the installation channel. The stud 10 is inserted into the installation channel of the first pipe section 11. The push rod 2 is slidably inserted into the second pipe section 12. The positioning member 5 is set at the rear end of the second pipe section 12.

[0028] Furthermore, such as Figures 3 to 9 As shown, to prevent the stud 10 from being installed too far back, increasing the difficulty of pushing out the stud 10, a boss 111 for stopping the stud 10 is provided on the inner wall of the front end of the second pipe section 12. In this embodiment of the present invention, the outer diameters of the first pipe section 11 and the second pipe section 12 are the same and they are arranged coaxially. The inner diameter of the first pipe section 11 is larger than the inner diameter of the second pipe section 12. Therefore, along the radial direction of the second pipe section 12, the inner wall of the second pipe section 12 protrudes from the inner wall of the first pipe section 11 to form the boss 111 for stopping the stud 10 at the front end of the second pipe section 12. During processing, the first pipe section 11 and the second pipe section 12 are integrally formed.

[0029] Furthermore, when the stud 10 is partially inserted into the first pipe section 11, with the remaining portion protruding outside, a slight impact can cause the stud 10 to fall off. To ensure the stability of the stud 10 installation, the length of the first pipe section 11 is greater than or equal to the length of the stud 10, ensuring that the stud 10 is completely inserted into the installation channel of the first pipe section 11. In this embodiment of the invention, the length of the first pipe section 11 is the same as the length of the stud 10. When installing the stud 10, the stud 10 is completely inserted into the installation channel within the first pipe section 11, with the rear end of the stud 10 abutting against the front end face of the boss 111. The front end of the stud 10 is flush with the front end of the first pipe section 11. When the positioning member 5 abuts against the first stop 3, the front end of the push rod 2 is flush with the front end of the boss 111. The distance between the first stop 3 and the second stop 4 is equal to the length of the first pipe section 11.

[0030] When installing the stud 10, insert the stud 10 into the installation channel of the first pipe section 11, then insert the front end of the sleeve 1 into the stud insertion groove 91, and then push the push rod 2 to slide along the installation channel. The stud 10 is pushed forward by the push rod 2 and fitted onto the positioning pin 92 in the stud insertion groove 91. When the second stop 4 abuts against the positioning element 5, the stud 10 separates from the first pipe section 11. Through the above design, not only can the stud 10 be installed quickly and conveniently, but it also avoids the worker having to remove the stud installation fixture before the stud 10 is separated from the first pipe section 11, thus preventing the stud 10 from being pulled out of the installation. At the same time, it also prevents the stud 10 from falling off due to slight impact.

[0031] Furthermore, such as Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, this utility model embodiment also has other installation methods: When installing the stud 10, the sleeve 1 is inserted into the stud embedding groove 91 of the mold 9. When the front end of the sleeve 1 abuts against the left side wall of the stud embedding groove 91, the stud 10 is fitted onto the positioning pin 92 at the end of the stud embedding groove 91. Then, the push rod 2 is pushed forward to fix the stud 10 in place, preventing the stud 10 from moving after installation. Then, the sleeve 1 is pulled backward. When the positioning member 5 abuts against the second stop 4, the front end of the push rod 2 moves into the front opening of the first pipe section 11, so that the stud 10 is disengaged from the first pipe section 11. This installation can also ensure that the stud 10 is installed in place, and can also prevent the workers from removing the stud installation tool before the stud 10 is separated from the first pipe section 11, thereby taking out the installed stud 10. At the same time, it can also prevent the stud 10 from falling off due to slight collisions.

[0032] Furthermore, such as Figure 3 and Figure 4As shown, to accommodate the installation of studs 10 at different angles, the first pipe section 11 is made of an elastic tube, and the stud 10 is interference-fitted with the first pipe section 11. In this embodiment of the invention, the sleeve 1 is made of steel, the first pipe section 11 and the second pipe section 12 are integrally formed, the stud 10 is inserted into the first pipe section 11 and interference-fitted with the first pipe section 11, and when the sleeve 1 and the push rod 2 slide relative to each other, the push rod 2 overcomes the friction between the stud 10 and the inner wall of the first pipe section 11 to separate the stud 10 from the first pipe section 11.

[0033] Furthermore, such as Figure 7 and Figure 8 As shown, a groove 6 is provided on the top rod 2. The length direction of the groove 6 extends along the length direction of the top rod 2. A portion of the top rod 2 at one end of the groove 6 forms a first stop 3, and a portion of the top rod 2 at the other end of the groove 6 forms a second stop 4. One side edge of the positioning member 5 extends into the groove 6. In this embodiment of the present invention, a radially recessed groove 6 can be formed on the surface of the push rod 2 by machining. When the positioning member 5 abuts against the first stop 3, the distance from the front end of the push rod 2 to the front end of the first pipe section 11 is the minimum sliding distance. The interval distance between the first stop 3 and the second stop 4 (i.e., the length of the groove 6) should be greater than or equal to the minimum sliding distance. In this embodiment of the present invention, when the positioning member 5 abuts against the first stop 3, the front end of the push rod 2 is flush with the front end of the boss 111. The interval distance between the first stop 3 and the second stop 4 is equal to the length of the first pipe section 11. When the positioning member 5 abuts against the second stop 4, the front end of the push rod 2 extends into the opening at the front end of the first pipe section 11 to push the stud 10 out of the installation channel of the sleeve 1.

[0034] Furthermore, such as Figure 7 and Figure 8 As shown, the rear end of the sleeve 1 is fixedly fitted with an annular platform 7. The annular platform 7 is fixedly fitted to the rear end of the second pipe section 12. During processing, it is integrally formed with the first pipe section 11 and the second pipe section 12. The annular platform 7 can be used to fix the positioning component 5 on one hand, and on the other hand, it can be used to pull the finger tray of the sleeve 1 backward.

[0035] Furthermore, such as Figure 7 and Figure 8 As shown, the positioning component 5 is a positioning plate, which is fixed to the rear end face of the annular platform 7. The positioning plate extends into the groove 6 on the side near the top rod 2. A screw hole is provided on the rear end face of the annular platform 7, and a mounting hole is provided on the positioning plate. A screw 8 is installed in the mounting hole, and the screw 8 passes through the mounting hole and the screw hole in sequence to detachably install the positioning plate onto the annular platform 7.

[0036] Furthermore, such as Figure 5As shown, a stop 21 is provided at the rear end of the push rod 2. A spring 13 is sleeved on the push rod 2 between the stop 21 and the annular platform 7. One end of the spring 13 abuts against the annular platform 7, and the other end of the spring 13 abuts against the stop 21. When installing the stud 10, the push rod 2 is pushed forward and / or the sleeve 1 is pulled back, and the spring 13 is compressed. When the stud 10 is installed in place and the stud installation tool is removed from the stud insertion groove 91, the spring 13 rebounds and pushes the sleeve 1 and the push rod 2 to reset, facilitating the installation of the next stud 10.

[0037] like Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, based on the stud installation fixture provided in the above embodiments, a preferred embodiment of this utility model provides an injection mold for adapting to the stud installation fixture. The injection mold includes a mold body 9, on which a stud insertion groove 91 for installing a stud 10 and a positioning pin 92 disposed within the stud insertion groove 91 are provided. One end of the positioning pin 92 is fixed to the side wall within the stud insertion groove 91. In this embodiment of the utility model, the stud insertion groove 91 is horizontally arranged, and the right end of the stud insertion groove 91 forms an insertion inlet for a sleeve 1 on the surface of the mold body 9. The left end of the positioning pin 92 is fixed to the groove wall at the left end of the stud insertion groove 91. The stud 10 has an installation through hole. The front end of the sleeve 1 is inserted into the stud insertion groove 91, and the push rod 2 is moved to push the installation through hole of the stud 10 onto the positioning pin 92. The structure and usage method of the stud installation fixture have been discussed above and will not be repeated here.

[0038] The working process of this utility model is as follows: When installing the stud 10, the stud 10 is inserted into the installation channel of the first pipe section 11, and then the front end of the sleeve 1 is inserted into the stud embedding groove 91. Then, the push rod 2 is pushed to slide along the installation channel, the spring 13 is continuously compressed, the stud 10 is pushed forward by the push rod 2 and is fitted onto the positioning pin 92 in the stud embedding groove 91. When the second stop 4 abuts against the positioning part 5, the stud 10 is separated from the first pipe section 11, the stud installation fixture is removed, the push rod 2 is released, the spring 13 rebounds, and the push rod 2 is reset.

[0039] Alternatively, when installing the stud 10, the positioning element 5 abuts against the first stop block 3, the stud 10 is fully inserted into the installation channel within the first pipe section 11, the rear end of the stud 10 abuts against the front end face of the boss 111, and the front end of the stud 10 is flush with the front end of the first pipe section 11; then, the sleeve 1 is inserted into the stud insertion groove 91 of the mold 9, and when the front end of the sleeve 1 abuts against the left side wall of the stud insertion groove 91, the stud 10 is fitted onto the positioning pin 92 at the end of the stud insertion groove 91. The stud 10 has been installed in place; then push the push rod 2 forward to fix the stud 10 in place and prevent the stud 10 from moving. At the same time, pull the sleeve 1 backward to separate the sleeve 1 from the stud 10. The spring 13 is continuously compressed. When the positioning part 5 abuts against the second stop 4, the front end of the push rod 2 moves into the front opening of the first pipe section 11. The stud 10 is disengaged from the first pipe section 11. The stud installation fixture is removed. The push rod 2 is released, the spring 13 rebounds, and the sleeve 1 and the push rod 2 are reset.

[0040] In summary, this utility model provides a stud installation fixture and injection mold, which includes a sleeve 1 and a push rod 2 slidably inserted into the installation channel of the sleeve 1. The stud 10 is inserted into the installation channel at the front end of the push rod 2. In use, the stud 10 is first inserted and fixed in the installation channel. Then, the sleeve 1 is inserted into the stud embedding groove 91 of the injection mold to guide the sliding of the stud 10, so that the installation through hole of the stud 10 is aligned with the positioning pin 92 in the stud embedding groove 91. Then, the push rod 2 is pushed to mount the stud 10 onto the positioning pin 92. Continuing to push the push rod 2 will install the stud 10 into place. The installation of the stud 10 in this utility model relies on the pushing of the push rod 2, enabling the installation of studs 10 at different angles. This solves the technical problem that existing stud installation tools are only suitable for vertical installation of studs and cannot install horizontal studs. Horizontal stud installation relies on manual labor, which not only poses a risk of burns but also reduces production efficiency.

[0041] Furthermore, the push rod 2 is provided with a first stop 3 and a second stop 4 arranged at intervals along its length. A sliding groove is formed between the first stop 3, the second stop 4, and the push rod 2. The positioning element 5 is located at the rear end of the sleeve 1, with one edge extending into the sliding groove. In use, the push rod 2 slides relative to the sleeve 1, and the positioning element 5 slides in the sliding groove. The first stop 3 abuts against the positioning element 5, which can prevent the push rod 2 from sliding backward and avoid the push rod 2 from detaching from the sleeve 1. Since the sleeve 1 is inserted into the stud embedding groove 91 when installing the stud 10, it is difficult to determine whether the stud 10 installed in place has detached from the stud installation fixture. To avoid taking the stud 10 out when removing the sleeve 1, the abutment between the positioning element 5 and the second stop 4 prompts the operator to separate the stud 10 from the first pipe section 11, preventing the operator from removing the stud installation fixture before the two are separated, and thus taking out the stud 10 that has been installed in place.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
