Description

Technical Field

[0001] The utility model relates to injection molding production equipment, in particular to injection molding retaining spring installation equipment. Background Art

[0002] In the production of some injection molded parts, some need to install bolts on the injection molded parts, some are produced by encapsulating the injection molded parts with glue, and some are clamped by retaining rings after the injection molding is completed. In particular, some special knurled bolts are usually installed with retaining rings on the bolts after the injection molding is completed, and then the two are pressed into the injection molded parts.

[0003] The installation of retaining springs in the prior art is usually to fix the injection molded part in a fixture, then fix the retaining spring and bolts manually or put them into a positioning fixture, and then press them into the product. Since the retaining spring needs to be installed on the injection molded part through friction, the size of the retaining spring is usually larger than the mounting hole or mounting groove on the injection molded part. Therefore, when pressing down, if the retaining spring cannot be placed vertically correctly, it will cause additional pressure damage to the injection molded part, causing it to be scrapped. After the installation is completed, the bolts and the product need to be taken out from their respective fixtures together, which is very inconvenient. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3The utility model provides a technical solution: an injection molding retaining spring installation device, comprising a support frame 1, a cylinder 2 and a bearing platform 3, the cylinder 2 is installed at the upper end of the support frame 1, and a bearing platform 3 is provided directly below the cylinder 2, the bearing platform 3 is used to place injection molding parts, a placement tube 4 is provided at the center of the bearing platform 3, the bottom of the placement tube 4 is fixed on a base 5, and the base 5 is fixedly installed at the lower end of the support frame 1, the bearing platform 3 is installed on the base 5 and can float up and down above the base 5, and the initial height of the floating bearing platform 3 is higher than the placement tube 4, which is convenient for placing injection molding parts and bolts on which retaining springs are installed.

[0024] In this embodiment, the support frame 1 includes a bottom plate 11, a connecting rod 12 and a top plate 13. The bottom plate 11 and the top plate 13 are connected by the connecting rod 12. According to the size of different injection molded parts, the support frame 1 of different heights can be replaced to improve the scope of application.

[0025] In this embodiment, the cylinder 2 is fixed to the side of the top plate 13. The fixing position of the cylinder 2 can be adjusted as needed, and the upper and lower heights of the cylinder 2 can be adjusted to meet the installation requirements of some injection molded parts with higher heights.

[0026] In this embodiment, a boss 31 is provided on the top surface of the support platform 3. The boss 31 can clamp the injection molded part to prevent the injection molded part 31 from moving left and right. The boss 31 can also be provided at different positions according to the structure of the injection molded part.

[0027] In this embodiment, the supporting platform 3 is provided with symmetrically arranged limit screws 32, which pass through the supporting platform 3 and are threadedly connected to the base 5 at the bottom. The position of the limit screw 32 is fixed, and the supporting platform 3 is limited by the head of the limit screw 32, so that the height position of the supporting platform 3 is fixed when it is not subject to downward pressure.

[0028] In this embodiment, a spring 33 is provided on the limit screw 32, and the spring 33 is located between the supporting platform 3 and the base 5. After the retaining spring is installed, the spring 33 can lift the injection molded part and the retaining spring at the same time, so that the retaining spring and the bolt are separated from the placement tube 4, without having to take out the injection molded part and the retaining spring separately from the two sets of clamps.

[0029] In this embodiment, a placement hole 41 is provided on the placement tube 4. The inner diameter of the placement hole 41 is smaller than the width of the retaining ring. The placement hole 4 is used to place bolts, and the hole diameter of the placement hole 41 needs to match the diameter of the placed bolts.

[0030] Working principle: first, place the bolt with the retaining spring into the placement tube 4, then place the injection molded part onto the supporting platform 3 and clamp it through the set boss 31, and finally press the injection molded part downward through the cylinder 2. At this time, the supporting platform 3 on which the injection molded part is placed is subjected to pressure to compress the spring 33 below, and the supporting platform 3 is pressed down to make the retaining spring with the bolt below enter the mounting hole or mounting groove of the injection molded part. Then, after being pressed down to the set position, the output shaft of the cylinder 2 rises. At this time, the spring 33 is no longer subjected to external force and will restore the supporting platform 3. During the resetting process, due to the friction between the retaining spring and the injection molded part, the retaining spring and the bolt will be lifted out of the placement tube 4 through the injection molded part, and then you only need to remove the injection molded part from the supporting platform 3.

[0031] Based on the above, the utility model can press down the injection molded part through the cylinder, and through the floating supporting platform, after the installation of the retaining spring, the injection molded part can take out the retaining spring and the bolt from the placement tube together, which is convenient for the installation of the retaining spring and the unloading; the placement tube provided in the utility model can keep the bolt and the retaining spring always placed vertically, so that the retaining spring can always enter the injection molded part vertically, preventing the retaining spring from causing additional pressure and scratches on the injection molded part.

[0032] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
