Description

Technical Field

[0001] This utility model belongs to the field of metal insert removal technology, and is particularly related to a tooling for removing metal inserts from plastic products. Background Technology

[0002] Some lead-acid battery casings have a plastic top and a metal insert at the bottom, such as... Figure 3 The illustration shows a plastic product with a U-shaped metal insert located at the lower part of one end of the product's main body. The metal insert has a first connecting hole at its bottom and a second connecting hole on its outward-facing side. Currently, the injection molding industry often uses direct scrapping for defective insert plastic products. However, removing the metal insert is difficult, hindering recycling and resulting in material waste. Therefore, improvements are necessary.

[0003] To address the aforementioned deficiencies in the prior art, this application provides a tooling for removing metal inserts from plastic products. In use, the tooling can fix the metal inserts from the plastic products and can heat the metal inserts, facilitating their removal and recycling.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A tooling for removing metal inserts from plastic products, comprising:

[0006] A support plate on which a heating tube is vertically mounted, the diameter of which matches the diameter of the first connecting hole at the bottom of the metal insert of the plastic product;

[0007] A push rod is spaced above the support plate and moves along the length of the support plate. The diameter of the push rod is smaller than the diameter of the second connecting hole on the side of the metal insert. When the heating tube is in the first connecting hole of the metal insert of the plastic product, and the side of the metal insert with the second connecting hole is perpendicular to the push rod, the push rod is aligned with the second connecting hole.

[0008] Furthermore, a connecting block is provided at one end of the top of the support plate, and the push rod passes through the connecting block.

[0009] Furthermore, a spring is provided on the side of the connecting block near the heating tube. The spring is sleeved on the push rod, and a limiting ring is provided on the periphery of the push rod. The limiting ring is connected to the end of the spring away from the connecting block. When the spring is in its natural state, the heating tube is in the first connecting hole of the metal insert of the plastic product, and when the side of the metal insert with the second connecting hole is perpendicular to the push rod, the push rod is in the second connecting hole.

[0010] Furthermore, a handle is attached to the end of the push rod away from the heating element.

[0011] Furthermore, the support plate is provided with a pair of alignment plates. When the heating tube is in the first connecting hole of the metal insert of the plastic product, and the side of the metal insert with the second connecting hole is perpendicular to the push rod, the two ends of the plastic product respectively abut against the pair of alignment plates.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This tooling can fix metal inserts in plastic products and can heat the metal inserts to facilitate their removal and recycling.

[0014] 2. After setting up the alignment plates, place the plastic product between a pair of alignment plates, so that the second connecting hole of the metal insert can be aligned with the push rod, achieving rapid alignment. Attached Figure Description

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] This application provides a tooling for removing metal inserts from plastic products, such as... Figures 1-2 As shown, it includes a support plate 1, a heating tube 2, a push rod 4, etc.

[0021] Specifically, the heating tube 2 is vertically mounted on the support plate 1, and the diameter of the heating tube 2 matches the diameter of the first connecting hole 3011 at the bottom of the metal insert 301 of the plastic product 3; the push rod 4 is spaced above the support plate 1 and moves along the length of the support plate 1. The diameter of the push rod 4 is smaller than the diameter of the second connecting hole 3012 on the side of the metal insert 301. When the heating tube 2 is inside the first connecting hole 3011 of the metal insert 301 of the plastic product 3, and the side of the metal insert 301 with the second connecting hole 3012 is perpendicular to the push rod 4, the push rod 4 is aligned with the second connecting hole 3012.

[0022] In actual use, the scrapped plastic product is placed on the support plate 1, and the first connecting hole 3011 at the bottom of the metal insert 301 of the plastic product 3 is aligned with the heating tube 2 and fitted over the heating tube 2. At the same time, the second connecting hole 3012 on the side of the metal insert 301 is aligned with the push rod 4. Then, the push rod 4 is pushed into the second connecting hole 3012 to restrict the upward movement of the metal insert 301. Then, the heating tube 2 is controlled to heat the metal insert 301. After the metal insert 301 is heated to a certain temperature, the part of the plastic product 3 in contact with the metal insert 301 will melt. At this time, the body of the plastic product 3 can be lifted upward to separate the metal insert 301. Then, the push rod 4 is pulled out of the second connecting hole 3012 to remove the metal insert 301 for recycling.

[0023] Specifically, a connecting block 5 is provided at one end of the top of the support plate 1, and the push rod 4 passes through the connecting block 5 and moves back and forth along the length of the support plate 1 on the connecting block 5.

[0024] Specifically, a spring 6 is provided on the side of the connecting block 5 near the heating tube 2. The spring 6 is sleeved on the push rod 4. A limiting ring 401 is provided on the periphery of the push rod 4. The limiting ring 401 is connected to the end of the spring 6 away from the connecting block 5. When the spring 6 is in its natural state, the heating tube 2 is located in the first connecting hole 3011 of the metal insert 301 of the plastic product 3, and the side of the metal insert 301 with the second connecting hole 3012 is perpendicular to the push rod 4. When it is necessary to fix the metal insert 301, the push rod 4 is released from being pulled outward. The push rod 4 will move into the second connecting hole under the elastic force of the spring 6. When it is necessary to release the fixation of the metal insert 301, the push rod 4 can be pulled outward from the second fixing hole. More specifically, a handle 402 is connected to the end of the push rod 4 away from the heating tube 2, which facilitates the back-and-forth movement of the push rod 4.

[0025] Preferably, the support plate 1 is provided with a pair of alignment plates 7. When the heating tube 2 is located in the first connecting hole 3011 of the metal insert 301 of the plastic product 3, and the side of the metal insert 301 with the second connecting hole 3012 is perpendicular to the push rod 4, both ends of the plastic product 3 abut against the pair of alignment plates 7 respectively. By setting the alignment plates 7, placing the plastic product 3 between the pair of alignment plates 7 can align the second connecting hole 3012 of the metal insert 301 with the push rod 4, achieving rapid alignment.

[0026] The above are only some of the embodiments listed in this application and are not intended to limit this application.
