Description

Technical Field

[0001] The present invention relates to the technical field of molds, and more specifically, to an injection mold base with efficient ejection and anti-deformation functions. Background Art

[0002] At present, there are many problems in the actual application of traditional mold bases. On the one hand, the ejection structure of the existing mold base is inefficient and often cannot quickly and accurately eject the molded product from the mold. This not only prolongs the production cycle, reduces production efficiency, but also may cause the product to cool excessively in the mold due to untimely ejection, increasing the demolding difficulty and even possibly damaging the product.

[0003] On the other hand, the lack of anti-deformation ability is also a major shortcoming of traditional mold bases. During the injection molding process, due to the flow characteristics of the plastic melt, uneven cooling, and unreasonable mold structure design, etc., the product is prone to deformation problems. And the existing mold bases usually cannot effectively prevent this kind of deformation, resulting in low dimensional accuracy and poor appearance quality of the produced products, and it is difficult to meet the production requirements of high-precision products.

[0004] In addition, with the continuous improvement of the market's requirements for product quality and production efficiency, the limitations of traditional injection mold bases are becoming more and more obvious. For example, in the production of some plastic products with complex shapes, the ejection structure of traditional mold bases is difficult to adapt to complex mold cavities, and it is easy to occur incomplete ejection or damage the product during the ejection process. At the same time, for some large products, the anti-deformation ability of traditional mold bases is even more difficult to meet the requirements, and it is easy to cause serious deformation of the product after demolding, affecting the use performance and market competitiveness of the product. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an injection mold base with efficient ejection and anti-deformation functions, which can realize efficient mold opening and accelerate the separation efficiency of the mold and the mold core.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0017] Compared with the prior art, the advantages of the present invention are as follows: The present invention is provided with a unique air nozzle structure, including a plurality of air nozzles on the flat section of the mold cavity and an included angle air nozzle at the included angle of the mold cavity. Through the action of an air pump, the formed plastic product can be uniformly stressed from multiple directions to achieve efficient ejection. Compared with the prior art, the problems of untimely ejection and incomplete ejection that may occur in the traditional ejection structure are avoided, and the production efficiency is greatly improved.

[0018] The layered design of the angled nozzle, with the air hole layer, output layer, and intake layer cooperating with each other, makes the gas transmission more stable and efficient, further enhancing the ejection effect. In the prior art, it is often difficult to achieve effective ejection at the complex angled mold cavities, and this patent well solves this problem.

[0019] By using a two-way air pump, the air extraction and air output functions can be flexibly switched according to actual needs, providing more powerful power support for the ejection process. The air pumps in the prior art have a single function and cannot meet the complex ejection requirements.

[0020] The plastic film laid on the upper end face of the male mold can play a good protective role for the product during the injection molding process, preventing deformation caused by uneven flow and uneven cooling of the melt. The prior art usually lacks such effective anti-deformation measures, making it difficult to guarantee the dimensional accuracy and appearance quality of the product.

[0021] In the design of the mold lifting mechanism, whether it is a clamping type or a winding type, it can smoothly lift the plastic film during the mold lifting process, avoiding causing additional stress to the product, thereby reducing the risk of deformation. Compared with the relatively rough mold lifting methods in the prior art, the anti-deformation effect of this patent is more significant.

[0022] The cooperation between the trigger part and the circuit system realizes the linkage control of the mold lifting mechanism and the air pump, making the entire ejection and mold lifting process more automated and intelligent. In the prior art, there is often a lot of manual intervention, with cumbersome operations and prone to errors. BRIEF DESCRIPTION OF THE DRAWINGS

A lower output layer 213-2 is arranged at the lower end of the air hole layer 213-1. The output layer 213-2 is provided with air pipes arranged in contact with each other to ensure the air output direction. An intake layer 213-3 is arranged at the lower end of the output layer 213-2, and the intake layer 213-3 communicates with the air guiding layer 211.

The air pipe 111 is coupled to the air pump 11, and the air pipe 111 is coupled to the wall of the air guiding layer 211.

[0028] At the upper end of the male mold 2, there is a female mold 3. The female mold 3 is arranged opposite to the male mold 2, and the female mold 3 and the male mold 2 match each other. A second chamber is formed in the middle of the lower end of the female mold 3, and a female mold core 31 is embedded in the second chamber. The female mold core 31 abuts against the wall of the second chamber, and the female mold core 31 is detachably connected to the female mold. A mold opening that matches the male mold core 21 is formed in the middle of the female mold core 31.

[0029] The upper end of the female mold 3 is coupled to an upper sealing plate 4. A pouring nozzle 41 is formed through the middle of the upper sealing plate 4. The pouring nozzle 41 communicates with the inside of the female mold 3 and the female mold core 31, so that when the pouring nozzle 41 is used for injection molding, it enters the mold opening and the mold cavity of the mold core. A positioning block 42 is arranged at the upper end of the pouring nozzle 41. The positioning block 42 is detachably connected to the upper end of the upper sealing plate 4. The positioning block 42 is located at the upper end of the pouring nozzle 41 and always fits the pouring nozzle 41.

[0030] A plastic film 5 is laid on the upper end face of the male mold 2. The plastic film 5 fits the upper end faces of the male mold 2 and the male mold core 21, and the area of the plastic film 5 is always larger than that of the male mold 2.

[0031] Demolding mechanisms 6 are arranged on both sides of the female mold 3. The demolding mechanisms 6 are used to clamp the edges of the plastic film 5 on both sides. The demolding mechanism 6 includes a telescopic rod 61 which has the ability to expand and contract. After contraction, the telescopic rod 61 is placed inside the wall of the female mold 3. A film clamp 62 is arranged at the lower end of the telescopic rod 61.

The film clamp 61 is fixedly connected to the lower end of the telescopic rod 61, and a driving member is arranged on the upper side of the film clamp 61 to drive the film clamp 61 to perform the clamping operation. When in use, the film clamp 62 moves up and down with the contraction of the telescopic rod 61. During the injection molding process, the male mold 2 and the female mold 3 are in relative abutment, and the demolding mechanism 6 is placed inside the side walls of the female mold 3, so that the male mold 2 and the female mold 3 are tightly abutted against each other.

[0032] Guide posts 7 are arranged on both sides between the male mold 2 and the female mold 3. The guide posts 7 are embedded in the male mold 2, and the lower ends of the guide posts 7 are fixedly connected to the male mold 2. The guide posts 7 themselves have the ability to expand and contract, and the wall of the guide posts 7 is slidably connected to the wall of the male mold. The upper ends of the guide posts 7 are fixedly connected to the female mold 3, so that when the guide posts 7 expand and contract up and down, they drive the female mold 3 to move up and down.

[0033] Working principle: In this embodiment, before injection molding, the plastic film is laid on the upper end face of the male mold, and the plastic film is completely adsorbed on the cavity surface of the male mold core by air pumping, including the corners being adsorbed tightly. After the plastic film is adsorbed tightly, the female mold is retracted close to the male mold through the guide posts until they are in abutment and seamless. At the same time, the demolding mechanism is also placed inside the female mold to ensure that there are no air gaps around the mold core. At this time, injection molding material is injected into the male mold core and the female mold core through the nozzle. After standing for a certain time to cool, the guide posts extend upward, the male mold and the female mold are separated. At this time, the formed module is placed on the male mold core. At the same time, the demolding mechanism extends upward and clamps the edges of the plastic film on both sides and pulls it upward, and the air pump switches to discharging air to blow the plastic film to separate together, completing the demolding.

[0034] Embodiment 2:

[0035] Please refer to Figures 5-8, An injection mold base with an efficient ejection and anti-deformation function. Different from Embodiment 1, the demolding mechanism 6 includes a rotating shaft 63, which is rotatably connected to the lower end of the telescopic rod 61. The demolding mechanism 6 is arranged on both sides in the width direction of the male mold core 21. A film take-up wheel 64 is arranged between the rotating shafts 63, and the film take-up wheel 64 is fixedly connected to the rotating shaft 63. A film clamping cavity is formed on the wheel body wall of the film take-up wheel 64 so that the plastic film 5 is placed in the film clamping cavity without coming out. A motor is arranged outside the rotating shaft 63, and the rotating shaft 63 is electrically connected to the motor so that the rotating shaft 63 has the ability to rotate.

[0036] On both sides of the upper end of the male mold 2 at the lower end of the film take-up wheel 64, trigger parts 22 are arranged. A cavity is formed at the lower end of the trigger part 22 so that the trigger part 22 can be embedded in the cavity. A trigger spring 221 is arranged in the cavity. The lower end of the trigger spring 221 is fixedly connected to the lower wall of the cavity, and the upper end of the trigger spring 221 is fixedly connected to the lower end of the trigger part 22. The upper layer of the trigger part 22 is made of an insulating material, and the lower layer of the trigger part 22 is made of a metal material. Metal sheets 222 are arranged on both side walls of the cavity at the lower end of the trigger part 22. When the trigger part 22 is pressed down into the cavity, the metal sheets 222 always abut against the metal end of the trigger part 22. A power supply 23 is arranged outside the male mold 2, and the power supply 23 serves as the starting end of a circuit system. The circuit system is a series circuit and is sequentially connected with a power supply 23, a switch, the trigger parts 22 on both sides, the trigger springs 221 on both sides, the metal sheets 222 on both sides and an air pump 11. The trigger part 22, the trigger spring 221 and the metal sheet 222 serve as a break point of the circuit system. When the demolding mechanism 6 falls, it presses against the trigger part 22 to push the trigger part 22 into the cavity to touch the metal sheets 222 on both sides, so that the circuit system is in a conducting state. The circuit system only controls the air extraction operation of the air pump 11, and the air release operation is started through an external signal source in the demolding state.

[0037] Working principle: In this embodiment, for the air extraction start of the air pump, when the demolding mechanism is retracted, it presses against the trigger part, and through the trigger part entering the cavity and abutting against the metal sheets on both sides, one side of the circuit system is made conductive through the metal end and the metal sheet. For the circuit system to be completely connected and the air pump to extract air, both trigger parts on both sides need to be placed in the cavity to adsorb the plastic film completely on the cavity wall of the male mold core.
