AI Technical Summary
In existing injection molds, the embedded inserts in the mold are prone to float during the plastic filling process, resulting in the leakage of inserts on both sides of the front and rear mold products, and it is difficult to reach the IP68 waterproof level.
A single-side fixed wave bead positioning mechanism for embedded in mold is designed, including a hollow shell, a spring and a ball. The ball exposes the shrinking port under the action of spring force, and resists the interior of the embedded insert to achieve limiting and fixing.
Through the installation of this mechanism, the injection mold can be integrated with a better sealing effect, reduces the risk of seal leakage, and can achieve the waterproof level of high sealing requirements.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to a single-side fixed wave ball positioning mechanism for an embedded part in a mold. Background Art
[0002] Injection molds are components that give plastics their shape and size during molding. Although the structure of the mold may vary due to the type and performance of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, the basic structure is the same. Injection molds are basically composed of mold cores, mold bases, locating pins, nozzles, guide pins, guide sleeves, gap adjustment mechanisms, and cooling systems.
[0003] In order to achieve efficient production and improve product quality, in-mold embedding has been widely used in the mold field. However, in the prior art, in-mold embedding is to prevent the insert from floating during the plastic filling process, the front and rear molds need to add fixed positions, which will cause the inserts to leak on both sides of the front and rear mold products. Such in-mold embedding may require secondary repair, and of course it cannot meet the IP68 waterproof grade requirement. Summary of the invention
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a single-side fixed bead positioning mechanism for embedded parts in the mold, which can assist the injection mold to effectively fix the embedded parts.
[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows:
[0006] The invention discloses a single-side fixed ball positioning mechanism with an embedded molded part, comprising a hollow shell, the bottom of which is closed, a constriction is provided on the top of the shell, a spring and a ball are arranged in the inner cavity of the shell in sequence, one end of the spring is placed at the bottom of the shell, and the ball is placed between the other end of the spring and the constriction.
[0007] Preferably, the inner diameter of the necking is smaller than the diameter of the ball.
[0008] Preferably, threads are provided on the outer side of the casing.
[0009] The beneficial effects achieved by the utility model using the above structure are as follows:
[0010] The utility model discloses a single-sided fixed ball positioning mechanism for an embedded molded part. After the mechanism is installed on the positioning pin of the injection mold, the ball is exposed from the shrinkage under the action of the spring force and presses against the inside of the embedded molded part, thereby limiting and fixing the embedded mold. In this way, the injection mold can be sealed with glue as a whole, the sealing effect is better, and the risk of sealing leakage is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the planar structure of the utility model.
[0012] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0014] like Figure 1 As shown, the mold-embedded single-sided fixed ball positioning mechanism includes a hollow shell 1, the bottom of the shell 1 is closed 1-1, and a constriction 1-2 is provided on the top of the shell 1. A spring 2 and a ball 3 are sequentially arranged in the inner cavity of the shell 1, one end of the spring 2 is placed at the bottom of the shell 1, and the ball 3 is placed between the other end of the spring 2 and the constriction 1-2.
[0015] Preferably, the inner diameter of the necking 1 - 2 is smaller than the diameter of the ball 3 .
[0016] Preferably, threads are provided on the outer side of the casing 1 .
[0017] The utility model mold embedded insert single-sided fixed wave ball positioning mechanism is mainly installed on the injection mold for use. In the prior art, the injection mold generally includes a mold core 4 and a positioning pin 5. The utility model mold embedded insert single-sided fixed wave ball positioning mechanism is installed on the positioning pin 4. The specific installation method is not limited to the connection methods such as thread, welding, and inlay. The utility model is provided with a thread on the outer side of the housing 1, and its purpose is to be installed on the positioning pin 4 more conveniently and quickly. Of course, the later replacement is also very simple. The embedded insert 6 is installed on the positioning pin 4. Since the utility model is installed on the positioning pin 4, the inner diameter of the constriction 1-2 of the housing 1 of the utility model is smaller than the diameter of the ball 3. In this way, the ball 3 is partially exposed through the constriction 1-2 under the elastic force of the spring 2. The exposed part of the ball 3 will exert a force on the embedded insert 6 inside, and this force can firmly fix the embedded insert 6 on the positioning pin 4. In this way, during the injection molding process of the injection molding machine, the glue can be sealed as a whole, the sealing effect is better, and the risk of sealing leakage is reduced. The embedded product formed by the utility model can meet very high sealing requirements. The utility model is very suitable for the production of products with waterproof grade requirements, such as vehicle sunroofs, power batteries, VR wearable devices, electric vehicles, etc.
