Description

Technical Field

[0001] This utility model relates to the field of heating ceramic plate processing technology, specifically a pressing and molding mechanism for processing heating ceramic plates. Background Technology

[0002] Heating ceramic plates are a new generation of medium- and low-temperature heating elements produced by printing resistance paste directly onto alumina ceramic green bodies, firing them at a high temperature of around 1600℃, and then processing them with electrodes and leads. They represent another generation of products following alloy heating wires and PTC heating elements. The main material of the heating ceramic plate is alumina ceramic, which has good conductivity, mechanical strength, and high-temperature resistance. The production of heating ceramic plates requires a pressing and molding mechanism.

[0003] The patent application CN214561726U discloses a pressing and molding mechanism for processing heating ceramic plates. The mechanism includes a base, a top cabinet mounted on the top surface of the base, a bottom mold mounted inside the top cabinet, and a top mold mounted on top of the bottom mold. A first hydraulic cylinder is bolted to the bottom surface of the bottom mold via a telescopic rod, and a second hydraulic cylinder is bolted to the top surface of the top mold via a telescopic rod. A discharge device is provided on one side of the top surface of the base, and a discharge pipe is provided on the top surface of the top cabinet. The bottom mold and top mold can be pressed together by the first and second hydraulic cylinders, respectively. After pressing and molding, the bottom mold can be transported to the position of the discharge device by the first hydraulic cylinder. The bottom plate, folding plate, and template on the bottom mold can slide relative to each other, allowing the formed heating ceramic plate to be removed from the base, facilitating the unloading of the heating ceramic plate.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] In the processing of heating ceramic plates, after pressing and shaping, it is often necessary to flip and press again. After pressing one side, the ceramic plate is flipped in time to press the other side, which helps to eliminate air bubbles on both sides of the heating ceramic plate. Therefore, existing devices often add a matching flipping mechanism when pressing heating ceramic plates. When flipping heating ceramic plates after pressing and shaping, the flipping clamp is often set in a relatively simple way, which is not easy to match the height with the bottom support plate. When the heating ceramic plate is flipped and placed again, there is a certain error in height. It may be unstable during the flipping and placement process, resulting in cracks in the heating ceramic plate and affecting the product qualification rate. Utility Model Content

[0006] The purpose of this invention is to provide a pressing and molding mechanism for processing heating ceramic plates, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pressing and molding mechanism for processing heating ceramic plates includes a work box. Two sets of side plates are symmetrically and fixedly connected to both sides of the upper surface of the work box. A demolding cavity is provided on the upper surface of the work box between the two sets of side plates. A first push rod is provided inside the work box. A bottom support plate is fixedly connected to the output shaft end of the first push rod. The bottom support plate is slidably connected between the two sets of side plates. Second push rods are symmetrically arranged at the four corners of the top of the side plates. The top ends of the second push rods are connected to a top plate. A top pressure plate matching the bottom support plate is provided on the bottom surface of the top plate.

[0009] Two sets of brackets are symmetrically and fixedly installed on the top two sides of the side plate. A motor is slidably connected to the top surface of the bracket. A rotating shaft is fixedly connected to the output end of the motor. A flipping component is fixedly connected to one end of the rotating shaft. The flipping component matches the bottom plate.

[0010] Preferably, both sets of side plates are symmetrically provided with sliding grooves, and the four corners of the bottom support plate are symmetrically provided with fixed sliders, and the sliders are in sliding clearance fit with the sliding grooves.

[0011] Preferably, a hydraulic cylinder is fixedly installed at the center of the top of the top plate, and the output end of the hydraulic cylinder passes through and extends to the top surface of the top plate and is fixedly connected to the center of the top of the top pressure plate. Connecting components are provided between the two sides of the top surface of the top pressure plate and the two sides of the bottom surface of the top plate.

[0012] Preferably, the connecting assembly includes a top rod and a connecting rod, the top end of the top rod is fixedly connected to both sides of the bottom surface of the top plate, the connecting rod is slidably connected inside the top rod, and the bottom ends of the connecting rod are fixedly connected to both sides of the top surface of the top pressure plate.

[0013] A damping rod is provided between the top of the connecting rod and the inner top of the top rod. A compression spring is provided around the outer surface of the damping rod. When the top pressure plate presses down to press the heating ceramic plate, the stability of its up-and-down operation is increased by the connecting component.

[0014] Preferably, the upper surface of the bracket is provided with an electric slide table, the motor is disposed on the sliding platform of the electric slide table, an inner slider is slidably installed inside the sliding platform of the electric slide table, and an arc-shaped positioning frame is fixedly installed on the upper part of the inner slider, and the motor is snapped into the inside of the arc-shaped positioning frame.

[0015] Preferably, the flipping assembly includes a drive plate and a clamping plate. Two sets of drive plates are symmetrically arranged, and the clamping plates are symmetrically arranged on one side of the two sets of drive plates. Feeding plates are equidistantly arranged on the bottom support plate. A slot is provided between each set of feeding plates, and a corresponding slot is opened on the drive plate at the position of the slot between the feeding plates.

[0016] Preferably, control shafts are provided on the upper and lower sides of the drive plate, and the output ends of the control shafts are fixedly connected to one side of the clamping plate, and the clamping plates are controlled to close and open by the control shafts.

[0017] The clamp plate is movably inserted into the groove between the outer surface of the clamp plate and the feeding plate, and the clamp plate and the feeding plate are at the same height.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] 1. The heating ceramic plate to be processed is placed and molded through the set bottom support plate. During the molding process, the top pressure plate cooperates with the bottom support plate. The connecting component set between the top pressure plate and the top plate increases the stability when the top pressure plate is pressed down and retracted, reduces the positional displacement of the heating ceramic plate during molding, and improves the finished product effect of the heating ceramic plate molding.

[0020] 2. An electric slide is installed on a bracket symmetrically arranged on both sides of the base plate. The electric slide drives two sets of motors to move closer and further apart, which in turn allows two sets of flipping components fixed to the rotating shaft to move closer or further apart. When flipping is required, the two sets of flipping components move closer to the bottom surface of the heating ceramic plate and tighten them. The base plate is lowered by the control of the first push rod, and the heating ceramic plate is suspended between the two sets of flipping components for easy flipping. After the heating ceramic plate is flipped, the electric slide drives the two sets of flipping components to reset, achieving relatively precise flipping control and minimizing damage to the heating ceramic plate during the pressing and flipping process.

[0021] 3. The feeding plates, which are equidistantly arranged on the upper surface of the base plate, are matched with the clamping plates of the flipping assembly. The clamping plates are inserted and movably connected at the slot gap between the feeding plates, which is precisely matched with the working height. There will be no interference when flipping and clamping or when resetting and feeding after flipping. The consistent height makes it less likely for the heating ceramic plate to be unstable during the flipping and placement process, which may cause cracks in the heating ceramic plate and improve the processing effect of the heating ceramic plate.

Connecting components are provided between the two sides of the top surface of the top plate 7 and the two sides of the bottom surface of the top plate 6, which increases the stability of the top plate 7 when it is pressed down and retracted, reduces the positional displacement of the heating ceramic plate during molding, and improves the finished product effect of the heating ceramic plate being pressed and molded.

[0035] The connecting assembly includes a top rod 14 and a connecting rod 15. The top end of the top rod 14 is fixedly connected to both sides of the bottom surface of the top plate 6.

[0036] Example 2:

[0037] Based on Embodiment 1, this embodiment details the flipping component of Embodiment 1.

An inner slider is slidably installed inside the sliding platform of the electric slide table 801, and an arc-shaped positioning frame is fixedly installed on the upper part of the inner slider.

The consistent height makes it less likely for the heating ceramic plate to be unstable during the flipping and placement process, which may cause cracks in the heating ceramic plate and improve the processing effect.

[0040] Working principle: During use, the heating ceramic plate to be processed is placed and molded by the base plate 4. During the pressing process, the top plate 7 cooperates with the base plate 4. The electric slide 801 drives the two sets of motors 9 to move closer and further away, so that the two sets of flipping components fixedly connected to the rotating shaft 10 can move closer or further away. When flipping is required, the two sets of flipping components come close to the bottom surface of the heating ceramic plate and tighten it. The base plate 4 is lowered by the control of the first push rod 3, and the heating ceramic plate is suspended between the two sets of flipping components for easy flipping. After the heating ceramic plate is flipped, the electric slide 801 drives the two sets of flipping components to reset.

[0041] The feeding plates 19, which are equidistantly arranged on the upper surface of the base plate 4, are matched with the clamping plates 18 of the flipping assembly. The clamping plates 18 are movably inserted into the slot gap between the feeding plates 19, precisely matching the usage height. There is no interference when flipping and clamping or when resetting and feeding after flipping. The consistent height makes it less likely for the heating ceramic plate to be unstable during the flipping and placement process, which may lead to cracks in the heating ceramic plate. It is also convenient to flip the heating ceramic plate and perform double-sided pressing and molding, reducing air bubbles on both sides of the heating ceramic plate, enhancing the pressing effect, and improving the quality of the product.

Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
