Description

Technical Field

[0001] The utility model relates to the field of mold equipment, in particular to a nut tooling fixture used for the production of plastic products. Background Art

[0002] When some existing products are injection molded, nuts need to be placed into the mold after the injection molding is completed. The existing operation method is usually to manually place the nuts directly into the designated position. However, since the mold that has just completed the injection molding is usually very hot, the manual direct placement method is prone to burns on the hands, which is not conducive to employee safety. Waiting for the mold to cool down will reduce the efficiency of the process. Utility Model Content

[0003] The purpose of the utility model is to provide a nut tooling fixture for the production of plastic products, which can increase the efficiency and safety of the nut being loaded into a mold.

[0004] In order to solve the above technical problems, the utility model provides a nut tooling fixture for the production of plastic products, including a mold, a positioning plate arranged on one side of the mold, and a movable plate arranged on the side of the positioning plate away from the mold. The movable plate can be close to or away from the positioning plate. The positioning plate has a nut mounting position, and the nut is placed on the nut mounting position. A nut push pin is connected to the movable plate, and one end of the nut push pin is connected to the movable plate, and the other end is passed through the positioning plate. When the movable plate approaches the positioning plate, the nut push pin pushes the nut into the mold.

[0005] Furthermore, a positioning column is provided on one side of the positioning plate, and a positioning hole corresponding to the positioning column is provided on a side of the mold close to the positioning plate.

[0006] Furthermore, a guide post is connected between the positioning plate and the movable plate. When the movable plate approaches or moves away from the positioning plate, the movable plate moves along the axial direction of the guide post.

[0007] Furthermore, an elastic member is connected between the movable plate and the positioning plate.

[0008] Furthermore, a limiting block is provided on one side of the positioning plate close to the movable plate.

[0009] Furthermore, a side of the movable plate away from the positioning plate is connected to a panel, and one side of the panel is provided with a handle.

[0010] Furthermore, there is a gap between the panel and the movable plate.

[0011] Furthermore, a push rod is provided on a side of the movable plate away from the positioning plate.

[0012] The beneficial effect of the present invention is that after the mold that has just completed injection molding is opened, the positioning plate is aligned with one side of the mold for positioning, and then the movable plate is pressed to make the movable plate approach the positioning plate. At the same time, the movable plate pushes the nut push pin to move during the movement. When the nut push pin moves, it contacts and pushes the nut in the nut installation position, so that the nut is pushed to the specified position of the mold. Due to the advance positioning of the positioning plate, the installation position of the nut is sufficiently accurate. At the same time, since there is no need for manual direct contact with the mold during the installation of the nut, the high temperature of the mold itself will not affect the operator's operation process, which not only ensures the safety of the operator, but also increases the efficiency of the nut installation process.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0016] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0017] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0018] like Figure 1The utility model provides a nut tooling fixture for the production of plastic products, including a mold 1, a positioning plate 3 arranged on one side of the mold 1, and a movable plate 5 arranged on the side of the positioning plate 3 away from the mold 1. The movable plate 5 can be close to or away from the positioning plate 3. The positioning plate 3 has a nut mounting position, and the nut is placed on the nut mounting position. A nut push pin 11 is connected to the movable plate 5, and one end of the nut push pin 11 is connected to the movable plate 5, and the other end is passed through the positioning plate 3. When the movable plate 5 approaches the positioning plate 3, the nut push pin 11 pushes the nut into the mold 1.

[0019] After the mold that has just completed injection molding is opened, the positioning plate is aligned with one side of the mold for positioning, and then the movable plate is pressed to make the movable plate approach the positioning plate. At the same time, the movable plate pushes the nut push pin to move during the movement. When the nut push pin moves, it contacts and pushes the nut in the nut installation position, so that the nut is pushed to the specified position of the mold. Due to the prior positioning of the positioning plate, the installation position of the nut is accurate enough. At the same time, since there is no need for manual direct contact with the mold during the installation of the nut, the high temperature of the mold itself will not affect the operator's operation process, which not only ensures the safety of the operator, but also increases the efficiency of the nut installation process.

[0020] Preferably, a positioning column 2 is provided on one side of the positioning plate 3 , and a positioning hole 21 corresponding to the positioning column 2 is opened on a side of the mold 1 close to the positioning plate 3 .

[0021] Specifically, when positioning the positioning plate and the mold, the positioning posts are inserted into the positioning holes so that the positioning plate can be positioned by the positioning posts, thereby ensuring the accuracy of subsequent nut installation.

[0022] In some embodiments, the positioning holes 21 are arranged at the four corners of the mold 1 so that the arrangement of the positioning holes 21 does not affect the shape design of the molding space of the mold 1 and ensures the stability of the positioning of the movable plate 3 .

[0023] In some embodiments, a recessed surface is provided on one side of the mold 1 close to the movable plate 3, and the positioning holes 21 are disposed on four sides of the recessed surface 4. The advantage of this is that when the positioning column 2 of the movable plate 3 and the positioning hole 21 cooperate, the movable plate 3 will not directly contact the mold 1, thereby reducing the wear of the mold 1.

[0024] Preferably, a guide column 9 is connected between the positioning plate 3 and the movable plate 5. When the movable plate 5 approaches or moves away from the positioning plate 3, the movable plate 5 moves along the axial direction of the guide column 9, so that the movable plate is sufficiently stable during the movement process, and the direction of movement is restricted, avoiding the movable plate from being misaligned with the positioning plate when moving, causing the nut push pin to be offset.

[0025] Preferably, an elastic member 10 is connected between the movable plate 5 and the positioning plate 3 . When the elastic member 10 is in a natural state, the positioning plate 3 and the movable plate 5 are spaced apart.

[0026] Specifically, through the elastic force of the elastic member on the movable plate, after the operator pushes the nut to complete the installation, he releases the thrust, and the elastic member drives the movable plate to reset, ensuring the subsequent use of the movable plate; when the positioning plate 3 moves along the guide column 9 close to the movable plate 3, the elastic member 10 is compressed, which not only can cushion the impact on the movable plate, but also can make the elastic member 10 have the function of natural reset.

[0027] In one embodiment of this solution, the elastic member is a spring.

[0028] Preferably, a limiting block 4 is provided on one side of the positioning plate 3 close to the movable plate 5 .

[0029] Specifically, when the movable plate approaches the positioning plate, the limit block presses against one side of the positioning plate, so that the movable plate cannot continue to approach the positioning plate, and the nut push pin cannot continue to push the nut to move, thereby controlling the accuracy of the nut push pin on the nut insertion depth.

[0030] In some embodiments, the side of the limiting block 4 close to the positioning plate 3 is a soft layer to reduce the impact between the positioning plate 3 and the movable plate 5.

[0031] Preferably, the side of the movable plate 5 away from the positioning plate 3 is fixedly connected to the panel 6 by bolts or other connecting parts. The panel 6 has a handle 7 on one side, so that the operator can easily pick up the entire nut tooling fixture by holding the handle, and then conveniently use it with the mold.

[0032] Preferably, there is a gap between the panel 6 and the movable panel 5 .

[0033] Specifically, since the mold has a high temperature after injection molding, and the positioning plate and the movable plate may be affected by the high temperature, the gap is set to ensure a certain separation distance between the panel and the movable plate, and the temperature of the movable plate itself will not affect the panel, effectively reducing the possibility of operators being affected by high temperature.

[0034] It is worth mentioning that when a panel is connected to one side of the movable plate, an opening structure corresponding to the guide column is opened on the panel, so that the end of the guide column away from the positioning plate can pass through the opening structure to avoid the problem of mutual interference between the end of the guide column and the panel when the movable plate moves along the axial direction of the guide column, so that when the panel and the movable plate move at the same time, the panel and the movable plate also move along the axial direction of the guide column.

[0035] Preferably, a push rod 8 is provided on a side of the movable plate 5 away from the positioning plate 3 .

[0036] Specifically, when the positioning plate is positioned and the movable plate needs to be moved close to the positioning plate, the push rod is pushed so that the push rod drives the movable plate to move, so as to increase the movement stability of the movable plate, and there is no need to manually press the movable plate directly, further increasing the safety of the operator.

[0037] In one embodiment of the present scheme, a through hole corresponding to the push rod is opened on the panel, one end of the push rod is connected to the movable plate, and the other end passes through the through hole and is located on the side of the panel on the movable plate to avoid the use of the push rod being blocked by the panel.

[0038] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
