Description

Technical Field

[0001] This utility model relates to the field of heating technology, and in particular to a wax mold heating retainer with constant temperature function. Background Technology

[0002] In existing technologies, mold heating often uses a single heating source mode, such as providing heat only through a bottom heating plate or a top heating plate. This method is prone to uneven heating in different areas of the mold. For example, the temperature of the part near the heating source is too high, while the temperature of the part far from the heating source is insufficient. Especially for molds with complex cavities, it is difficult to effectively heat the inside of the cavity, which can easily lead to problems such as incomplete wax filling and inconsistent cooling rates. This can result in defects such as shrinkage marks, bubbles, and dimensional deviations in the wax mold. At the same time, the heat preservation performance of existing heating equipment is poor, and heat is easily diffused to the outside, which not only increases energy consumption but also causes large temperature fluctuations in the mold, making it difficult to maintain a stable constant temperature environment. Frequent adjustments to the heating power are required, which further affects the heating stability.

[0003] In terms of mold fixing, traditional equipment mostly uses manual clamps or fixed-size mechanical structures. Manual clamps rely on manual operation, and the clamping force is difficult to control. They are prone to being too loose, causing mold displacement, or too tight, causing mold damage. In addition, the operation efficiency is low. Fixed-size mechanical structures have poor adaptability and cannot meet the fixing requirements of molds of different sizes and shapes. When it is necessary to change the mold, the clamps need to be readjusted or replaced, which increases the complexity of operation and time cost. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a wax mold heating and holding device with constant temperature function, which can solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wax mold heating and holding device with constant temperature function, comprising a box body, a bracket fixedly connected to the top of the box body, a first rotating arm fixedly connected to the bracket, a heat preservation cover fixedly connected to the first rotating arm, a heating module fixedly connected to the heat preservation cover, and a heating rod fixedly connected to the bottom of the heat preservation cover;

[0006] An electromagnetic heating coil is installed inside the box.

[0007] The box is equipped with a first hydraulic pump. The output end of the first hydraulic pump is fixedly connected to a first hydraulic rod, and the other end of the first hydraulic rod is fixedly connected to a base insulation plate.

[0008] Four support seats are fixedly connected around the base insulation board. The four support seats are arranged in a circle. A second rotating arm is fixedly connected to each support seat. A clamp is fixedly connected to the second rotating arm.

[0009] A hydraulic push rod is fixedly connected to the middle part of the base insulation board. The other end of the hydraulic push rod is fixedly connected to the output end of the second hydraulic pump. A guide slider is fixedly connected to the other end of the second hydraulic pump. The guide slider is slidably connected to the clamp.

[0010] Preferably, the heating module is a silicone heating pad, which is attached and fixed to the surface of the heat preservation cover.

[0011] Preferably, the fixture has a sliding groove, and the guide slider is embedded in the sliding groove and slides in cooperation with the sliding groove.

[0012] Preferably, three heating rods are spaced apart along the length of the insulation cover, and the axis of the heating rods is perpendicular to the bottom surface of the insulation cover.

[0013] Preferably, the electromagnetic heating coil is embedded in the inner side wall and the inner bottom wall of the box, and the electromagnetic heating coil corresponds to the projection area of ​​the base insulation plate.

[0014] Preferably, the four support seats are arranged in a circular pattern with equal angles around the base insulation plate, and the included angle between two adjacent support seats is 90°.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The wax mold heating holder with constant temperature function is a common type of mold fixing device in the prior art. The mold fixing is mostly done by manual clamps or single-size fixing structures, which have poor adaptability and are prone to mold displacement during heating due to unstable fixing. This utility model uses four circumferentially arranged support seats and a clamp connected by a second rotating arm. With the linkage control of guide slider and hydraulic push rod, it can automatically clamp molds of different sizes and shapes through hydraulic drive. The circumferentially symmetrical clamping method can ensure that the mold is subjected to uniform force and avoid position deviation caused by loosening during heating.

[0017] (2) In the existing technology, the mold placement and heating cover opening and closing of the wax mold method with constant temperature function rely heavily on manual operation, which is inefficient and poses safety hazards (such as contact with high-temperature parts). This utility model realizes the automatic opening and closing of the heat preservation cover through the first rotating arm, realizes the mold lifting and lowering through the linkage of the first hydraulic pump and the first hydraulic rod, and automatically loosens and tightens the clamp driven by the second hydraulic pump, reducing manual intervention, improving operating efficiency and reducing the risk of operators coming into contact with high-temperature areas.

[0018] (3) The wax mold heating and holding device with constant temperature function is a common feature in the prior art. The heating, fixing and heat preservation functions often require multiple independent devices to cooperate, which occupy a lot of space and are complicated to coordinate. This utility model integrates the heating, fixing, heat preservation and driving structure into the box and related components. The overall structure is compact. Moreover, through adjustable clamps and heating components that are adapted to different molds (such as heating rods that can be designed for the cavity), it can adapt to the wax mold forming needs from small precision molds to medium complex molds, and has a wider range of applicable scenarios.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a wax mold heating and holding device with constant temperature function, including a box body 1, a bracket 2 fixedly connected to the box body 1, a first rotating arm 3 fixedly connected to the bracket 2, a heat preservation cover 4 fixedly connected to the first rotating arm 3, a heating module 5 fixedly connected to the heat preservation cover 4, and a heating rod 6 fixedly connected to the bottom of the heat preservation cover 4, the heating rod 6 extending into the cavity of the mold.

[0030] An electromagnetic heating coil is installed inside the box 1, and the electromagnetic heating coil inside the box 1 provides heating from the bottom and sides of the mold.

[0031] The box 1 is equipped with a first hydraulic pump 7. The output end of the first hydraulic pump 7 is fixedly connected to a first hydraulic rod 8. The other end of the first hydraulic rod 8 is fixedly connected to a base insulation plate 9. Four support seats 10 are fixedly connected around the base insulation plate 9. The four support seats 10 are arranged in a circle. A second rotating arm 11 is fixedly connected to each support seat 10. A clamp 12 is fixedly connected to the second rotating arm 11. The first hydraulic pump 7 inside the box 1 is initially in a retracted state. At this time, the first hydraulic rod 8 connected to the output end of the first hydraulic pump 7 is in a retracted state. The base insulation plate 9 is in a low position inside the box 1 under the action of the first hydraulic rod 8.

[0032] A hydraulic push rod 15 is fixedly connected to the middle part of the base insulation plate 9. The other end of the hydraulic push rod 15 is fixedly connected to the output end of the second hydraulic pump 14. A guide slider 13 is fixedly connected to the other end of the second hydraulic pump 14. The guide slider 13 is slidably connected to the clamp 12. The mold is placed on the clamp 12. Then the second hydraulic pump 14 is started. The output end of the second hydraulic pump 14 pushes the hydraulic push rod 15 to extend upward. The hydraulic push rod 15 drives the second hydraulic pump 14 and the guide slider 13 to move inward. Since the guide slider 13 is slidably connected to the clamp 12, when the slider slides inward, it will drive the clamp 12 and the second rotating arm 11 fixed thereto to rotate inward. Finally, the four clamps 12 clamp and fix the mold from all sides.

[0033] Working principle: The operation of this heating retainer starts from the mold clamping. First, the first hydraulic pump 7 inside the box 1 is initially in a retracted state. At this time, the first hydraulic rod 8 connected to the output end of the first hydraulic pump 7 is in a retracted state. The base insulation plate 9 is in a low position inside the box 1 under the drive of the first hydraulic rod 8. At the same time, the hydraulic push rod 15 connected in the middle of the base insulation plate 9 is not under force, and the second hydraulic pump 14 is also in an initial state.

[0034] The guide slider 13 connected to its other end is located in the initial position of the clamp 12, while the four second rotating arms 11 arranged in a circle on the support seats 10 around the base insulation plate 9 remain open.

[0035] The operator can place the mold on the fixture 12, and then start the second hydraulic pump 14. The output end of the second hydraulic pump 14 pushes the hydraulic push rod 15 to extend upward. The hydraulic push rod 15 drives the second hydraulic pump 14 and the guide slider 13 to move inward. Since the guide slider 13 is slidably connected to the fixture 12, when the slider slides inward, it will drive the fixture 12 and the second rotating arm 11 fixed thereto to rotate inward. Finally, the four fixtures 12 clamp and fix the mold from all sides.

[0036] After the mold is fixed, the first rotating arm 3 fixed on the bracket 2 on the top of the box 1 rotates, so that the heat preservation cover 4 connected to the first rotating arm 3 covers the top of the box 1. At this time, the heating module 5 on the heat preservation cover 4 is attached to the heat preservation cover 4, and the heating rod 6 under the heat preservation cover 4 extends into the cavity of the mold.

[0037] Subsequently, the heating system is activated. The heating module 5 on the insulation cover 4 heats the upper surface of the mold, the heating rod 6 heats the mold cavity locally, and the electromagnetic heating coil inside the box 1 heats the bottom and sides of the mold. The base insulation plate 9 reduces heat loss from the bottom of the mold, and the insulation cover 4 reduces heat diffusion from the top. The three work together to achieve uniform heating of the mold as a whole.

[0038] After the wax mold is formed, the heating system is first turned off. The insulation cover 4 is opened by rotating the first rotating arm 3 in the opposite direction. Then, the second hydraulic pump 14 is started and runs in the opposite direction. The hydraulic push rod 15 retracts, causing the guide slider 13 to slide downwards. The second rotating arm 11 and the clamp 12 rotate outwards to release the mold. Finally, the first hydraulic pump 7 is started. The first hydraulic pump 7 pushes the first hydraulic rod 8 upwards. The first hydraulic rod 8 lifts the base insulation plate 9 and the mold on it to the outside of the box 1, whereupon the operator can remove the formed wax mold. After the mold is removed, all parts are reset and ready for the next operation.

[0039] Structural Description:

[0040] Box 1: Box 1 is the basic load-bearing structure of the entire heating holder. It houses core components such as electromagnetic heating coils and first hydraulic pump 7. The top is used to form a closed heating space with the heat preservation cover 4. As the overall frame, it can integrate various functional components in an orderly manner, providing a stable closed environment for mold heating and forming, reducing the interference of the external environment on the heating process. At the same time, the internal space layout is reasonable, which facilitates the coordinated work of various components.

[0041] Support 2: Support 2 is fixedly connected to the box body 1 to support the first rotating arm 3 and provide a stable fulcrum for the rotation of the first rotating arm 3. With the support of support 2, the first rotating arm 3 and the connected heat preservation cover 4 can remain stable during rotation, ensuring that the heat preservation cover 4 can be accurately closed on the top of the box body 1 to ensure the sealed heating effect.

[0042] First rotating arm 3: The first rotating arm 3 is fixedly connected to the bracket 2, and one end is connected to the heat preservation cover 4. It can rotate around the bracket 2 to realize the opening and closing of the heat preservation cover 4. The rotating structure design makes the opening and closing operation of the heat preservation cover 4 simple and convenient, and can quickly realize the closing and separation of the heat preservation cover 4 and the box 1, which is convenient for the placement and removal of the mold, while ensuring the sealing when closing.

[0043] Insulation cover 4: The insulation cover 4 is fixedly connected to the first rotating arm 3. When closed, it can seal the top of the box 1. The heating module 5 is fixedly connected to the top and the heating rod 6 is fixedly connected to the bottom. On the one hand, it can reduce the heat diffusion from the top during the heating process and maintain the temperature stability inside the box; on the other hand, it integrates the heating module 5 and the heating rod 6 to achieve precise heating of the upper surface of the mold and the cavity, thereby improving heating efficiency.

[0044] Heating module 5: The heating module 5 is fixedly connected to the heat preservation cover 4. When the heat preservation cover 4 is closed, it heats the upper surface of the mold. It directly adheres to the heat preservation cover 4 and acts on the upper surface of the mold, which can specifically heat the upper part of the mold. In combination with other heating components, it makes the mold heat more evenly.

[0045] Heating rod 6: The heating rod 6 is fixedly connected to the bottom of the heat preservation cover 4. When the heat preservation cover 4 is closed, it extends into the cavity of the mold to provide local heating to the cavity. It can accurately act on this key part of the mold cavity, ensuring that the temperature of the cavity meets the requirements of wax mold forming, and improving the quality and precision of wax mold forming.

[0046] First hydraulic pump 7: The first hydraulic pump 7 is fixedly installed inside the housing 1, and its output end is fixedly connected to the first hydraulic rod 8. It provides power for the extension and retraction of the first hydraulic rod 8. The hydraulic drive method provides stable power and large output force, which can smoothly drive the first hydraulic rod 8 and subsequent components to move. The extension and retraction of the first hydraulic rod 8 can be precisely controlled by controlling the operation of the hydraulic pump.

[0047] First hydraulic rod 8: One end of the first hydraulic rod 8 is fixedly connected to the output end of the first hydraulic pump 7, and the other end is fixedly connected to the base insulation plate 9. Under the drive of the first hydraulic pump 7, it extends and retracts, driving the base insulation plate 9 to rise and fall. As a transmission component connecting the first hydraulic pump 7 and the base insulation plate 9, it can effectively transmit the power of the first hydraulic pump 7, realize the raising and lowering of the base insulation plate 9 and the mold on it, and facilitate the removal and placement of the mold.

[0048] Base insulation plate 9: The base insulation plate 9 is fixedly connected to the first hydraulic rod 8. The mold is placed on it, which can reduce the heat loss at the bottom of the mold and effectively prevent the heat at the bottom of the mold from spreading outward. Together with the insulation cover 4 and the electromagnetic heating coil, it maintains the overall temperature stability of the mold and reduces energy loss.

[0049] Support base 10: There are four support bases 10 in total, which are arranged in a circle and fixedly connected to the base insulation plate 9. They are used to support the second rotating arm 11. The circular arrangement can make the clamping force of the second rotating arm 11 and the clamp 12 on the mold more uniform. The fixed support of the support base 10 ensures the stability of the second rotating arm 11 during the rotation process.

[0050] Second rotating arm 11: The second rotating arm 11 is fixedly connected to the support base 10, and one end is connected to the clamp 12. It can rotate under the drive of the guide slider 13. The opening and closing of the clamp 12 is realized by the rotation. It has a simple structure and flexible operation, and can adapt to the clamping requirements of molds of different sizes.

[0051] Clamp 12: The clamp 12 is fixedly connected to the second rotating arm 11. Under the drive of the second rotating arm 11, it clamps or releases the mold from all sides. By holding the mold from all sides, it can firmly fix the mold on the base insulation plate 9, prevent the mold from shifting during heating and molding, and ensure the molding accuracy of the wax mold.

[0052] Guide slider 13: The guide slider 13 is fixedly connected to the second hydraulic pump 14 and slidably connected to the clamp 12. Under the push of the hydraulic push rod 15, it drives the clamp 12 and the second rotating arm 11 to move. The sliding connection makes the driving force transmission of the guide slider 13 to the clamp 12 more stable, and can accurately control the movement trajectory of the clamp 12, ensuring the accuracy of clamping and releasing actions.

[0053] Second hydraulic pump 14: One end of the second hydraulic pump 14 is fixedly connected to the guide slider 13, and the other end is fixedly connected to the hydraulic ejector rod 15. It provides power for the extension and retraction of the hydraulic ejector rod 15 and provides stable power output. By controlling the extension and retraction of the hydraulic ejector rod 15, the movement of the guide slider 13 is precisely controlled, thereby realizing the stable clamping and reliable release of the mold by the fixture 12.

[0054] Hydraulic push rod 15: One end of the hydraulic push rod 15 is fixedly connected to the output end of the second hydraulic pump 14, and the other end is fixedly connected to the middle part of the base insulation plate 9. It extends and retracts under the drive of the second hydraulic pump 14, driving the movement of related components. As a transmission component, it can effectively transmit the power of the second hydraulic pump 14 to the guide slider 13 to realize the action of the clamp 12. Its extension and retraction movement is smooth, ensuring the reliability of the action of the clamp 12.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
