Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, specifically to a mold frame for injection molds that is easy to clean. Background Technology

[0002] Injection molds are tools used to produce plastic products; they are also tools that give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and after cooling and solidification, obtaining the molded product. The mold frame is the support for the mold and is used to assist in the processing of the mold;

[0003] Existing injection molds typically use a mold frame to fix the fixed mold and the moving mold on the same straight line. During injection, an electric telescopic mechanism on the mold frame drives the moving mold to engage with the fixed mold, forming a sealed injection cavity and facilitating injection. However, during subsequent cleaning, the cleaning personnel are positioned under the moving mold. If a malfunction occurs or the electric telescopic mechanism is accidentally activated, it can easily cause injury to the cleaning personnel, increasing the danger of cleaning. Furthermore, the mold can obstruct the cleaning process, making it difficult for the cleaning personnel to operate, thus increasing the cleaning difficulty and reducing cleaning efficiency. Therefore, we propose a mold frame for injection molds that is easier to clean. Utility Model Content

[0004] The main objective of this invention is to provide a mold base for injection molds that is easy to clean, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold frame for easy cleaning of injection molds, comprising a base plate and a fixed frame, wherein the fixed frame is fixedly connected to one end of the upper surface of the base plate, and limit grooves are provided on both sides of the base plate, wherein a threaded rod is provided for lateral rotation of the limit grooves, a processing cavity is provided inside the fixed frame, and a fixed base is slidably provided at the bottom end of the processing cavity, wherein threaded holes are provided on both sides of the bottom end of the fixed base, and the bottom end of the fixed base is threadedly connected to the surface of the threaded rod through the threaded holes, a motor is embedded and connected to one side of the limit groove, and the power output end of the motor is fixedly connected to one end of the threaded rod, and a positioning slot is provided on the upper surface of the fixed base, wherein a fixed mold is detachably connected to the inner cavity of the positioning slot.

[0006] Preferably, a spring rod is embedded in the inner cavity of the processing cavity and on one side relative to the fixed base, and a clamping block adapted to the positioning groove is detachably connected to the inner side of the spring rod.

[0007] Preferably, an electric telescopic rod is embedded and connected to the top of the fixed frame, and the telescopic end of the electric telescopic rod passes through the top of the fixed frame and extends to the upper end of the inner cavity of the fixed frame.

[0008] Preferably, the upper end of the processing cavity is provided with a movable mold, and the upper surface of the movable mold is detachably connected to the telescopic end of the electric telescopic rod.

[0009] Preferably, the base plate surface is provided with a matching control panel, and the control panel is electrically connected to the motor via wires.

[0010] Preferably, an anti-slip pad is fixedly connected to the inner side wall of the clamping block.

[0011] Preferably, a safety photoelectric sensor is embedded in the top of the inner cavity of the processing chamber near the feed inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the coordinated arrangement of a fixed base, a motor, a threaded rod, a threaded hole, and a limiting slide groove, allows the motor to rotate counterclockwise after injection molding via a control structure. This rotation drives the threaded rod to move backward along the limiting slide groove, causing the fixed base, which is threaded to it, to move backward. During this movement, the fixed mold mounted at the top is removed from the fixed frame, exposing it to the outside environment for easy cleaning. This process avoids placing body parts under the moving mold, ensuring safety during cleaning. Furthermore, the cleaning process is unobstructed, effectively reducing cleaning difficulty and improving cleaning efficiency.

[0014] 2. This utility model uses a fixed base, a positioning slot, a spring rod, and a clamping block. The fixed mold is engaged with the upper end of the fixed base through the positioning slot, while the clamping block applies a clamping force to the fixed mold placed in the positioning slot under the action of the spring rod, thereby fixing the fixed mold in the positioning slot of the fixed base. During the outward movement of the fixed base, the spring rod will drive the clamping block to automatically reset and release the clamping effect on the fixed mold. When the fixed base and the fixed mold installed on the upper end are removed from the fixed frame, the fixed mold can be quickly disassembled, thereby further reducing the cleaning difficulty and improving the cleaning efficiency.

[0020] 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.

[0021] Example

[0022] Please see Figure 1 - Figure 4 The illustration shows a mold frame for easy cleaning of injection molds, including a base plate 1 and a fixed frame 2. The fixed frame 2 is fixedly connected to one end of the upper surface of the base plate 1. Limiting grooves 12 are formed on both sides of the base plate 1. A threaded rod 9 is rotatably mounted on each limiting groove 12. A processing cavity 4 is formed inside the fixed frame 2. A fixed base 7 is slidably mounted on the bottom end of the processing cavity 4. Threaded holes 10 are formed on both sides of the bottom end of the fixed base 7, and the bottom end of the fixed base 7 is threadedly connected to the surface of the threaded rod 9 through the threaded holes 10. A motor 8 is embedded in one side of the limiting groove 12, and the power output end of the motor 8 is fixedly connected to one end of the threaded rod 9. The fixed base 7 has a positioning slot 11 on its upper surface. The positioning slot 11 is detachably connected to a fixed mold 6. After injection molding, the control structure operates the motor 8 to drive the threaded rod 9 to rotate counterclockwise, and drives the fixed base 7, which is threaded to it, to move backward along the limiting slide groove 12. During the movement, the fixed mold 6 installed at the top is moved out of the fixed frame 2, thus exposing the fixed mold 6 to the outside world, which is convenient for workers to clean. During the cleaning process, it is avoided to place body parts under the moving mold 5, ensuring safety during cleaning. The cleaning process is not obstructed, effectively reducing the difficulty of cleaning and improving the cleaning efficiency.

[0023] A spring rod 13 is embedded in the inner cavity of the processing cavity 4 and on one side relative to the fixed base 7. A clamping block 14 adapted to the positioning groove is detachably connected to the inner side of the spring rod 13. When the fixed base 7 moves the fixed mold 6 to the fixed frame 2, the clamping block 14 will abut against the back of the fixed mold 6. Under the push of the spring rod 13, the clamping plate can cooperate with the fixed base 7 to tightly clamp the fixed mold 6 on the fixed base 7, making the fixed mold 6 easy to disassemble and assemble, effectively reducing the difficulty of later maintenance and cleaning, and improving the use effect.

[0024] The fixed frame 2 is fitted with an electric telescopic rod 3 at its top, and the telescopic end of the electric telescopic rod 3 passes through the top of the fixed frame 2 and extends to the upper end of the inner cavity of the processing cavity 4. The upper end of the inner cavity of the fixed frame 2 is provided with a moving mold 5, and the upper surface of the moving mold 5 is detachably connected to the telescopic end of the electric telescopic rod 3. The electric telescopic rod 3 can drive the moving mold 5 to move up and down, so that it can cooperate with the fixed mold 6 to form a sealed space for injection molding and shaping. After injection, it can be opened and closed quickly, which facilitates demolding and effectively improves injection molding efficiency.

[0025] The base plate 1 is equipped with a control panel, which is electrically connected to the motor 8 via wires. The control panel allows for easy control of the motor 8 to rotate forward and backward during adjustment, thereby facilitating the control of the fixed base 7 to move the fixed mold 6 back and forth within the fixed frame 2, and making it easier to adjust the position during cleaning.

[0026] The clamping block 14 is fixedly connected to an anti-slip pad on its inner sidewall, and a safety photoelectric sensor is embedded in the top of the processing cavity 4 near the feed port. When the clamping block 14 clamps the mold 6, the anti-slip pad effectively improves the anti-slip effect of the clamping block 14, thereby ensuring the fixing effect and ensuring the stability during injection molding. During the injection molding process, when a human body part is inserted into the mold frame, the safety photoelectric sensor will detect the human body part and transmit a signal to the control terminal. The control terminal will automatically close the injection molding structure to avoid injury to the human body and effectively improve the safety during injection molding.

[0027] It should be noted that this utility model is a mold frame for injection molds that is easy to clean. During cleaning, the control structure used in conjunction with the motor 8 drives the threaded rod 9 to rotate counterclockwise, which in turn drives the fixed base 7, which is threaded to it, to move outward along the limiting slide groove 12. During the movement, the fixed mold 6 installed on the upper surface is moved out of the fixed frame 2, thus exposing the fixed mold 6 to the outside of the fixed frame 2. At the same time, during the outward movement, the spring rod 13 will drive the clamping block 14 to automatically reset, and the fixed mold 6 will gradually separate from the clamping block 14, thereby releasing the clamping effect on the fixed mold 6. When the fixed base 7 and the fixed mold 6 installed on the upper end are moved out of the fixed frame 2, the fixed mold 6 can be quickly disassembled, which is convenient for workers to clean. During the cleaning process, it is important to avoid placing body parts under the moving mold 5 to ensure safety during cleaning. Furthermore, the cleaning process is not obstructed, effectively reducing the difficulty of cleaning and improving cleaning efficiency.
