Description

Technical Field

[0001] This utility model relates to the field of injection mold technology for bracket production, specifically an injection mold for bracket production. Background Technology

[0002] Injection molds for stent production are high-precision tools specifically designed for manufacturing plastic stents. They are typically made of steel or aluminum alloy and use an injection molding process to inject molten plastic into the mold cavity. After cooling and solidification, a stent product with a specific structure and function is formed. Mold design must consider the stent's load-bearing capacity, dimensional stability, and ease of demolding. It usually includes core components such as a mold core, mold cavity, ejection system, and cooling system. Suitable for medical devices, electronic equipment, and industrial components, it features efficient mass production of complex-shaped plastic stents.

[0003] In actual production, after the injection-molded bracket product has cooled, the ejection mechanism of the mold will push the finished product out through the precisely designed ejector pin. However, due to the limited contact area between the ejector pin and the product, the resulting adhesion force is small, which makes the finished product prone to free fall during demolding. These fallen bracket products may collide with surrounding production equipment, resulting in quality problems such as scratches on the product surface and dimensional deformation, which seriously affect the appearance integrity and assembly accuracy of the product. To address this, we propose an injection mold for bracket production. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for bracket production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for bracket production, comprising mold body A and mold body B, wherein the surface of mold body B is provided with a collecting structure, the collecting structure comprising a fixing plate, the fixing plate being fixedly connected to the surface of mold body B, a rectangular rod being fixedly connected to the surface of the fixing plate, the surface of the rectangular rod having a plurality of circular holes, a slider being fitted onto the surface of the rectangular rod, a pin being slidably passed through the surface of the slider, the size of the pin being adapted to the size of the circular holes, and a collecting frame being fixedly connected to the surface of the slider.

[0006] The effect achieved by the above components is as follows: by setting up a collection structure, it is easy to collect the fallen brackets, avoid the brackets from falling and causing impact, thereby ensuring the appearance integrity and assembly accuracy of the brackets.

[0007] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the slider, respectively.

[0008] The effect achieved by the above components is that the pin is inserted into the round hole with the help of the spring's contraction force. The spring improves the stability of the pin's insertion into the round hole and prevents the pin from falling out of the round hole due to shaking.

[0009] Preferably, a protective pad is fixedly connected to the inner wall of the collection frame, and the protective pad is made of rubber.

[0010] The effect achieved by the above components is that the rubber protective pads on the inner wall of the collection frame can absorb the impact force when the bracket falls, preventing surface scratches.

[0011] Preferably, the surface of the collection frame has several rectangular holes.

[0012] The effect achieved by the above components is as follows: because the temperature is high after the support is poured, the support will dissipate heat when it falls into the collection frame. Since the surface of the collection frame has several rectangular holes, the heat will be discharged from the rectangular holes, thereby improving the heat dissipation effect of the support.

[0013] Preferably, two support arms are fixedly connected to the surface of the mold B, and a support plate is fixedly connected to the end of the support arm away from the mold B, and the support plate is attached to the surface of the collection frame.

[0014] The effect achieved by the above components is that the support plate reaches the position to support the collection frame, thereby improving the load-bearing capacity of the collection frame.

[0015] Preferably, the surface of the support plate is provided with a groove, and the inner wall of the groove is rotatably connected to a plurality of rotating wheels.

[0016] The effect achieved by the above components is that the collection frame slides along the surface of the rotating wheel when it moves, and the rotating wheel rotates in the groove with the help of the force of the collection frame moving. The rotating wheel reduces the friction of the collection frame when it moves, thereby facilitating the movement of the collection frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model, by setting up a collection structure, achieves the following: the mold body B drives the fixed plate to move, the fixed plate moves the rectangular rod, and the rectangular rod moves the collection frame with the help of a slider. This causes the collection frame to move to the center directly below the middle of the mold body A and the mold body B. At this time, when the bracket falls from the mold body A, the bracket will fall into the collection frame, which is convenient for collecting the fallen bracket and avoids the bracket from impacting the ground. This ensures the appearance integrity and assembly accuracy of the bracket. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-2 This utility model provides a technical solution: an injection mold for bracket production, including mold body A1 and mold body B2. The surface of mold body B2 is provided with a collection structure 3. The collection structure 3 includes a fixing plate 301, which is fixedly connected to the surface of mold body B2. A rectangular rod 302 is fixedly connected to the surface of the fixing plate 301. The surface of the rectangular rod 302 is provided with several circular holes 304. A slider 303 is fitted onto the surface of the rectangular rod 302. A pin 305 slides through the surface of the slider 303. The size of the pin 305 is adapted to the size of the circular holes 304. A collection frame 306 is fixedly connected to the surface of the slider 303. By setting the collection structure 3, it is convenient to collect fallen brackets, avoid the brackets from falling and impacting the brackets, and thus ensure the appearance integrity and assembly accuracy of the brackets.

[0026] Reference Figure 3 and Figure 4As shown in this embodiment: a spring 307 is fitted onto the arc surface of the pin 305. The two ends of the spring 307 are fixedly connected to the pin 305 and the slider 303, respectively. The pin 305 is inserted into the circular hole 304 by the contraction force of the spring 307. The spring 307 improves the stability of the pin 305 within the circular hole 304, preventing it from falling out due to shaking. A protective pad 308, made of rubber, is fixedly connected to the inner wall of the collection frame 306. The rubber protective pad 308 absorbs the impact when the support falls, preventing surface scratches. Several rectangular holes 309 are formed on the surface of the collection frame 306. Because the support is at a high temperature after casting, it will dissipate heat when it falls into the collection frame 306. Since the surface of the collection frame 306 has several rectangular holes 309, the heat will dissipate through these holes, thus improving the heat dissipation effect of the support. Two support arms 310 are fixedly connected to the surface of the mold body B2. A support plate 311 is fixedly connected to the end of the support arm 310 away from the mold body B2. The support plate 311 fits against the surface of the collection frame 306, and the support plate 311 supports the collection frame 306, thereby improving the load-bearing capacity of the collection frame 306. A groove 312 is formed on the surface of the support plate 311. Several rotating wheels 313 are rotatably connected to the inner wall of the groove 312. When the collection frame 306 moves, it slides along the surface of the rotating wheels 313. The rotating wheels 313 rotate in the groove 312 with the help of the force of the moving collection frame 306. The rotating wheels 313 reduce the friction of the collection frame 306 when it moves, thereby facilitating the movement of the collection frame 306.

[0027] Working principle: After the injection-molded bracket product has cooled, the ejection mechanism of the mold pushes the bracket out of the mold body A1. Due to the limited contact area of ​​the ejector rod, the bracket easily detaches from the ejector rod and falls freely. Pulling the pin 305 causes the pin 305 to move and slide within the slider 303, gradually disengaging from the round hole 304. The movement of the pin 305 stretches the spring 307. After the pin 305 disengages from the round hole 304, pulling the slider 303 causes it to move and slide along the surface of the rectangular rod 302. 3. During movement, the collection frame 306 will move, sliding along the surface of the support plate 311. By moving the position of the collection frame 306, it is ensured that the collection frame 306 is always directly below the path of the bracket's fall. At this time, the pin 305 is released, and the pin 305 will be inserted into the round hole 304 by the force of the spring 307's contraction. The pin 305 reaches the position of the limiting slider 303, thereby limiting the position of the collection frame 306. The support plate 311 reaches the position of supporting the collection frame 306, thereby raising the collection frame 306. The collection frame 306 slides along the surface of the rotating wheel 313 when it moves. The rotating wheel 313 rotates within the groove 312 with the force of the moving collection frame 306. The rotating wheel 313 reduces the friction of the collection frame 306 when it moves, thus facilitating the movement of the collection frame 306. When the mold body B2 moves, it drives the fixed plate 301 to move. The movement of the fixed plate 301 drives the rectangular rod 302 to move. The movement of the rectangular rod 302, through the slider 303, drives the collection frame 306 to move, thereby... When the collection frame 306 moves to the center of the mold A1 and the mold B2, the support will fall into the collection frame 306 when it falls from the mold A1. The rubber protective pad 308 on the inner wall of the collection frame 306 can absorb the impact force when the support falls and prevent surface scratches. Because the support is at a high temperature after casting, it will dissipate heat when it falls into the collection frame 306. Since the surface of the collection frame 306 has several rectangular holes 309, the heat will be discharged from the rectangular holes 309, thereby improving the heat dissipation effect of the support.
