[0001] The utility model relates to the technical field of injection molding part processing equipment, in particular to an auxiliary fixing device for curved surface injection molding parts. Background Art

[0002] An injection mold is a tool for producing plastic products. Injection molding is a processing method used when mass-producing some parts with complex shapes. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after demolding and cooling and solidifying, a formed product is obtained.

[0003] Among automotive parts, a large number of injection molding parts are required, especially thin curved surface injection molding parts. However, during injection molding demolding, due to their still having a certain temperature, the thin curved surface injection molding parts are prone to a certain degree of deformation, thus reducing the processing accuracy of the curved surface injection molding parts. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide an auxiliary fixing device for curved surface injection molding parts.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] An auxiliary fixing device for curved surface injection molding parts includes a T-shaped support frame. At both ends of the horizontal bar corresponding to the T-shape of the support frame, a clamping assembly is respectively provided. At the middle part of the horizontal bar corresponding to the T-shape of the support frame, a abutting part is provided. The clamping positions of the two clamping assemblies and the abutting position of the abutting part are all located on the curved surface of the curved surface injection molding part. At the end of the vertical bar corresponding to the T-shape of the support frame, a limiting part for limiting the position of the curved surface injection molding part is provided.

[0007] Further, the number of the abutting parts is two, and the two abutting parts are symmetrically distributed on the horizontal bar with the vertical bar as the axis of symmetry.

The clamp is used to fix the curved surface injection molding part on the clamping table. A first pressure sensor is embedded on the clamping table, and the first pressure sensor is electrically connected to an external controller.

[0026] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments as follows:

[0027] As Figures 1-7 shown, an auxiliary fixing device for a curved surface injection molded part provided by the present utility model includes a support frame in a T shape. A clamping assembly is respectively provided at both ends of the cross bar corresponding to the T shape of the support frame. An abutting part is provided in the middle of the cross bar corresponding to the T shape of the support frame.

A limiting part for limiting the position of the curved surface injection molded part is provided at the end of the vertical bar corresponding to the T shape of the support frame.

[0028] It can be known from the above description that the present utility model has the following beneficial effects:

[0029] An auxiliary fixing device for a curved surface injection molded part provided by the present utility model is used to assist in fixing the curved surface injection molded part just after injection molding and demolding, so as to avoid deformation due to the remaining temperature after injection molding and demolding. Specifically, the auxiliary fixing device includes a support frame in a T shape. A clamping assembly is respectively provided at both ends of the cross bar corresponding to the T shape of the support frame. An abutting part is provided in the middle of the cross bar corresponding to the T shape of the support frame. The clamping positions of the two clamping assemblies and the abutting position of the abutting part are all located on the curved surface of the curved surface injection molded part. A limiting part for limiting the position of the curved surface injection molded part is provided at the end of the vertical bar corresponding to the T shape of the support frame. During use, the curved surface injection molded part just after injection molding and demolding is placed on the support frame. One side of the curved surface injection molded part abuts against the limiting part, and the curved surface of the curved surface injection molded part abuts against the abutting part. Then, the clamping assembly is used to fix both ends of the other side of the curved surface injection molded part, so as to ensure that the clamped position of the curved surface injection molded part remains stable. After the curved surface injection molded part is completely cooled and solidified, it is taken off to complete the auxiliary fixing operation, thereby effectively avoiding the deformation of the curved surface injection molded part just after injection molding and demolding due to the remaining temperature.

[0030] Furthermore, the number of the abutting parts is two, and the two abutting parts are symmetrically distributed on the cross bar with the vertical bar as the axis of symmetry.

[0031] As can be seen from the above description, by the cooperation of the abutting part and the clamping assembly, and the clamping positions of the two clamping assemblies and the abutting position of the abutting part are both located on the curved surface of the curved surface injection molded part, the curvature of the curved surface injection molded part can be kept unchanged.

[0032] Further, the abutting part is composed of a metal sheet in a U-shape, and the metal sheet is welded to the support frame.

[0033] As can be seen from the above description, through the above structural design, the fixation of the metal sheet and the support frame is realized.

[0034] Further, the abutting part is composed of a metal sheet in a U-shape, and the metal sheet is detachably connected to the support frame.

[0035] As can be seen from the above description, through the above structural design, the fixation of the metal sheet and the support frame is realized. Further, by adopting a detachable connection, the position adjustment of the metal sheet can be facilitated to adapt to curved surface injection molded parts with different curvatures.

[0036] Further, the clamping assembly includes a clamping table and a clamp arranged on one side of the clamping table. The clamp is used to fix the curved surface injection molded part on the clamping table. A first pressure sensor is embedded in the clamping table, and the first pressure sensor is electrically connected to an external controller.

[0037] As can be seen from the above description, by adding a first pressure sensor on the clamping table, it can be detected whether the curved surface injection molded part is placed in place. When it is placed in place, the clamping assembly is operated to clamp and fix the curved surface injection molded part, avoiding repeated clamping.

[0038] Further, a second pressure sensor is arranged on the limiting part, and the second pressure sensor is electrically connected to an external controller.

[0039] As can be seen from the above description, by adding a second pressure sensor on the limiting part, it can be further detected whether the curved surface injection molded part is placed in place to ensure the accurate clamping position of the clamping assembly.

[0040] Further, it further includes a timing module and a display module, and the timing module and the display module are respectively electrically connected to an external controller.

[0041] Further, the timing module is a timer, and the display module is an LED indicator light.

[0042] As can be seen from the above description, by setting a time through the timing module, when the timing time ends, the controller controls the display module to give a prompt, indicating that the required fixing duration has been reached. The clamped and cured curved surface injection molded part can be removed, and the next curved surface injection molded part to be clamped and cured can be replaced, without manual judgment, avoiding affecting the curing effect.

[0043] Further, the support frame is composed of hollow steel pipes.

[0044] As can be seen from the above description, made of the above materials, it is not only convenient to obtain materials, but also high-temperature resistant.

[0045] The following are several preferred embodiments or application embodiments listed to help those skilled in the art better understand the technical content of the present invention and the technical contributions made by the present invention compared with the prior art:

[0046] Preferred Embodiment 1:

[0047] Such as Figures 1 to 7 As shown, an auxiliary fixing device for a curved surface injection molded part provided by the present invention includes a support frame 1 in a T shape; the support frame 1 is composed of hollow steel pipes, which is not only convenient to obtain materials, but also high-temperature resistant.

[0048] A clamping assembly 12 is respectively provided at both ends of the cross bar 11 corresponding to the T shape of the support frame 1. The clamping assembly 12 includes a clamping table 121 and a clamp 122 provided on one side of the clamping table 121. The clamp 122 is used to fix the curved surface injection molded part on the clamping table. Among them, the clamp can adopt existing manual clamps or electric clamps. A first pressure sensor is embedded in the clamping table 121, and the first pressure sensor is electrically connected to an external controller. The first pressure sensor can adopt existing products. By adding a first pressure sensor on the clamping table, it can be detected whether the curved surface injection molded part is placed in place. When it is placed in place, the clamping assembly is operated to clamp and fix the curved surface injection molded part, avoiding repeated clamping. The controller can adopt existing integrated chips, such as the STM32 series of embedded chips.

[0049] An abutting portion 13 is provided in the middle of the cross bar 11 corresponding to the T shape of the support frame 1. The number of the abutting portions 13 is two, and the two abutting portions 13 are symmetrically distributed on the cross bar 11 with the vertical bar as the axis of symmetry. In this embodiment, the abutting portion 13 is composed of a metal sheet in a U shape, and the metal sheet is welded or detachably connected to the support frame. Among them, detachable connection is preferably adopted, and the advantage is that the position of the metal sheet can be adjusted to adapt to curved surface injection molded parts with different curvatures.

[0050] The clamping positions of the two clamping assemblies and the abutting positions of the abutting portions are jointly located on the curved surface of the curved surface injection molded part 2; through the cooperation of the abutting portion and the clamping assembly, and the clamping positions of the two clamping assemblies and the abutting positions of the abutting portions are jointly located on the curved surface of the curved surface injection molded part, the curvature of the curved surface of the curved surface injection molded part can be kept unchanged.

[0051] The support frame 1 is provided with a limiting portion 141 for restricting the position of the curved surface injection molded part 2 at the end of the vertical rod 14 of the T shape. A second pressure sensor is provided on the limiting portion 141, and the second pressure sensor is electrically connected to an externally provided controller. The second pressure sensor can adopt the same product as the above-mentioned first pressure sensor. By adding a second pressure sensor on the limiting portion, it is possible to further detect whether the curved surface injection molded part is placed in place, ensuring the accurate clamping position of the clamping assembly.

[0052] Based on the above-mentioned first pressure sensor, second pressure sensor and controller, a timing module and a display module are added. The timing module and the display module are respectively electrically connected to an externally provided controller. In this embodiment, the timing module is a timer, and the display module is an LED indicator light. By setting the time through the timing module, when the timing time ends, the controller controls the display module to give a prompt, indicating that the required fixed duration has been reached, and the clamped and cured curved surface injection molded part can be removed and the next curved surface injection molded part to be clamped and cured can be replaced, without manual judgment, avoiding affecting the curing effect. The above-mentioned timing module and display module can both adopt existing products.

[0053] The working principle of an auxiliary fixing device for a curved surface injection molded part provided by the present utility model is as follows:

[0054] During use, the just injection molded and demolded curved surface injection molded part 2 is placed on the support frame 1. One side of the curved surface injection molded part 2 abuts against the limiting portion 141. At this time, the second pressure sensor feeds back the detected pressure value to the controller. The curved surface of the curved surface injection molded part 2 abuts against the upper surface of the abutting portion 13. Then, the clamping assembly 12 is used to fix both ends of the other side of the curved surface injection molded part 2. At this time, the first pressure sensor feeds back the detected pressure value to the controller. When the controller receives the pressure values of both pressure sensors and both reach the preset values, it controls the timer to start timing. When the preset duration is reached, it controls the LED indicator light to flash or display different colors according to a preset rule (used to represent different states), thereby indicating that the cooling and curing of the curved surface injection molded part is completed, that is, the auxiliary fixing operation of a curved surface injection molded part is completed. Using the above device can effectively avoid the deformation of the just injection molded and demolded curved surface injection molded part due to the residual temperature.
