Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection-molded inlays, in particular to an injection-molded inlay. Background Art
[0002] Injection molding is a common manufacturing technique that is often used to embed small parts of metal, ceramic, glass or other materials into plastic or other material products. This manufacturing process involves inserting one or more small parts into a mold, and then injecting plastic or other materials into the mold to embed these parts into the final product.
[0003] However, in the prior art, during injection molding, the inlay is placed in a designated mold in advance and fixed, and then the injection mold is closed and the plastic raw material is injected to melt. When the plastic is melted, it will fill the mold and cover materials such as metal, glass, wood, fiber, paper, etc. The pressure in the injection mold will ensure a strong bond between the metal and the plastic. After the plastic cools, the injection mold is opened, the injection molded part is taken out, and the inlay is completed. When the molten material is fitted with the inlay, air cannot be discharged in time, resulting in the inlay not being tightly fixed inside the mold and falling off. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides an injection-molded insert, aiming to improve the problem that the insert and the plastic cannot be stably fixed during injection molding, resulting in falling off after later use.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an injection-molded inlay, comprising a base, a lower side of the base is provided with an anti-slip groove, the upper side of the base is fixedly connected with a lower anti-slip pattern, the upper side of the lower anti-slip pattern is fixedly connected with a smooth groove, the front and rear sides of the smooth groove are provided with ventilation holes, the upper side of the smooth groove is fixedly connected with an upper anti-slip pattern, the upper side of the upper anti-slip pattern is fixedly connected with an upper opening, a plurality of exhaust grooves are provided inside the upper side of the upper opening, and the lower side of the inner wall of the upper opening is fixedly connected with a threaded groove.
[0006] As a further description of the above technical solution:
[0007] During injection molding, the gas that has not been discharged from the mold is discharged through the vent hole, and the gas is directed to the upper side of the upper opening through the exhaust groove, which will not affect the stability of the injection-molded insert inside the product. At the same time, the upper anti-slip pattern, lower anti-slip pattern and anti-slip groove play a stabilizing role when the bolt thread is connected inside the thread groove.
[0008] Furthermore, the lower side of the thread groove is fixedly connected to the upper side of the base, and the inner wall of the lower anti-slip pattern is fixedly connected to the lower side of the thread groove.
[0009] As a further description of the above technical solution:
[0010] The base, the lower anti-skid pattern, the smooth groove and the upper anti-skid pattern are fixed on the surface of the thread groove, and the injection-molded insert is stably fixed inside the product.
[0011] Furthermore, the two ventilation holes are arranged in the middle of the thread groove, and the inner wall of the upper anti-slip pattern is fixedly connected to the upper side of the thread groove.
[0012] As a further description of the above technical solution:
[0013] The vent hole vents air to the inside of the thread groove and then releases it to the upper side of the upper opening through the exhaust groove.
[0014] Furthermore, the lower sides of the plurality of exhaust grooves are opened on the upper side of the upper anti-slip pattern.
[0015] As a further description of the above technical solution:
[0016] The exhaust groove is opened on the upper side of the upper anti-slip pattern to facilitate exhaust.
[0017] Furthermore, the thread groove is made of stainless steel.
[0018] As a further description of the above technical solution:
[0019] The thread groove is made of stainless steel, which is a material that is resistant to corrosion, oxidation and rust. It has strong mechanical strength and can ensure the stability of the connection.
[0020] Furthermore, the upper anti-skid pattern, the smooth groove, the lower anti-skid pattern and the surface of the base are plated with any one of zinc and nickel coating materials.
[0021] As a further description of the above technical solution:
[0022] Galvanizing or nickel plating can form a protective layer on the base metal surface to prevent oxidation and corrosion. These coatings can increase the stability of the connection and extend its service life.
[0023] The utility model has the following beneficial effects:
[0024] In the utility model, by cooperating among the upper anti-skid pattern, the smooth groove, the vent hole, the lower anti-skid pattern and the exhaust groove, the injection-molded inlay can discharge the air between the inlay and the plastic in time through the small hole when the inlay is inlaid inside the plastic, thereby improving the fixing tightness between the inlay and the plastic and preventing it from falling off after later use.

[0030] 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.
[0031] Reference Figure 1-3The utility model provides an embodiment: an injection molded inlay, including a base 9, an anti-skid groove 8 is provided on the lower side of the base 9, a lower anti-skid pattern 3 is fixedly connected to the upper side of the base 9, a smooth groove 2 is fixedly connected to the upper side of the lower anti-skid pattern 3, and ventilation holes 7 are provided on the front and rear sides of the smooth groove 2, an upper anti-skid pattern 1 is fixedly connected to the upper side of the smooth groove 2, an upper opening 5 is fixedly connected to the upper side of the upper anti-skid pattern 1, a plurality of exhaust grooves 4 are provided inside the upper side of the upper opening 5, a threaded groove 6 is fixedly connected to the lower side of the inner wall of the upper opening 5, and the lower side of the threaded groove 6 is fixedly connected to the upper side of the base 9. The base 9 is fixed to the lower side of the threaded groove 6, so as to facilitate the stably fixing of the lower side of the injection molded inlay inside the product. The inner wall of the lower anti-skid pattern 3 is fixedly connected to the lower side of the thread groove 6. The lower anti-skid pattern 3 can be stably fixed inside the product when a bolt is screwed in. Two vent holes 7 are opened in the middle of the thread groove 6. The vent holes 7 guide the gas to the inside of the thread groove 6 and release it on the upper side of the upper opening 5 through the exhaust groove 4. The inner wall of the upper anti-skid pattern 1 is fixedly connected to the upper side of the thread groove 6. The upper anti-skid pattern 1 can be stably fixed inside the product when a bolt is screwed in. The lower side of multiple exhaust grooves 4 is opened on the upper side of the upper anti-skid pattern 1. The exhaust groove 4 facilitates the release of gas on the upper side of the injection molded insert. The thread groove 6 is made of stainless steel, which is a material that is corrosion-resistant, anti-oxidation, and not easy to rust. It has strong mechanical strength and can ensure the stability of the connection. The upper anti-skid pattern 1, the smooth groove 2, the lower anti-skid pattern 3 and the base 9 are coated with any one of zinc and nickel coating materials. Zinc plating or nickel plating can form a protective layer on the surface of the base metal to prevent oxidation and corrosion. These coatings can increase the stability of the connection and extend the service life.
[0032] The gas is discharged into the thread groove 6 through the vent holes on the surface of the injection molded insert, so that the molten material can fit tightly to the surface of the insert. The cooperation between the upper anti-skid pattern 1 and the lower anti-skid pattern 3 can achieve stable fixation of the insert. The anti-skid groove 8 opened on the lower side of the base can ensure that the insert can be stably fixed inside the product when the bolt is screwed in to avoid falling off. The surface of the smooth groove 2 is smooth, which is convenient for the discharge of gas. The gas is discharged through the multiple exhaust grooves 4 inside the upper opening 5 and discharged at the upper side of the upper opening 5.
[0033] Working principle: When using this injection molding insert, fix the injection molding insert in a pre-designed mold, and then close the mold to inject plastic raw materials to melt. When the plastic melts, it will fill the mold and cover metal, glass, wood, fiber, paper and other materials. The pressure in the injection mold will ensure a strong bond between the metal and the plastic. After the plastic cools, open the injection mold, take out the injection molded part, and complete the inlay. After that, when the molten material contacts the surface of the injection molding insert, some gas cannot be discharged in time. At this time, the injection molding will be used to remove the gas. The vent holes 7 opened on the surface of the injection-molded insert discharge the gas into the thread groove 6, so that the molten material can be tightly attached to the surface of the injection-molded insert. The cooperation between the upper anti-slip pattern 1 and the lower anti-slip pattern 3 can stably fix it in the molten product, and the anti-slip groove 8 opened on the lower side of the base 9 can stabilize the injection-molded insert inside the product when the bolts are screwed in, and prevent it from falling. The surface of the smooth groove 2 is smooth to facilitate the discharge of gas. The gas is discharged through the multiple exhaust grooves 4 opened in the upper opening 5 and discharged at the upper side of the upper opening 5.
