Description

Technical Field

[0001] The utility model relates to the technical field of multi-station box liner vacuum forming machines, and more specifically, to a multi-station box liner vacuum forming machine. Background Art

[0002] The multi-station box liner vacuum forming machine is a device used for the production, processing and forming of box-type bile ducts. It uses vacuum technology to adsorb silicone or other materials on the mold, and forms the desired shape through heating and cooling. Traditional molding machines usually use an ejector rod to eject the product during demolding. In this process, the product is subjected to a great impact at the moment the ejector rod contacts the product. When the product is not completely cooled, the impact may cause excessive local stress in the product, causing it to deform, further affecting product quality, thereby causing certain losses to the factory. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a multi-station box liner vacuum forming machine to solve the problem that the traditional forming machine easily causes product deformation during the demoulding process.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-station box liner vacuum forming machine, comprising

[0005] Mould;

[0006] A bracket, the bracket being arranged at the rear side of the mold;

[0007] A heating device, wherein the heating device is fixedly connected to the bottom of the bracket;

[0009] Wherein, the buffer assembly includes a lower slide cylinder, a first spring, an upper slide cylinder, a top block, a second spring, and a buffer plate, the bottom side of the lower slide cylinder is fixedly connected to the top side of the connecting plate, one end of the first spring is fixedly connected to the inner surface of the bottom side of the lower slide cylinder, the bottom side of the upper slide cylinder is fixedly connected to the other end of the first spring, the outer side of the upper slide cylinder is slidably connected to the inner surface of the circular hole on the surface of the extension plate, the bottom side of the top block is fixedly connected to the top side of the upper slide cylinder, one end of the second spring is fixedly connected to the top side of the top block, and the bottom side of the buffer plate is fixedly connected to the other end of the second spring.

[0010] The heating device includes a heating shell, a connecting rod, a temperature sensor, a resistance wire, and a control panel. The top side of the heating shell is fixedly connected to the bottom side of the bracket, one end of the heating shell is fixedly connected to the inner surface of the top side of the heating shell, the top side of the temperature sensor is fixedly connected to the other end of the connecting rod, the two ends of the resistance wire are fixedly connected to the inner surfaces of both sides of the heating shell, and one end of the control panel is fixedly connected to the front surface of the heating shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model starts the power supply of the electric push rod, and the electric push rod extends to lift the buffer assembly through the connecting plate. When the buffer plate contacts the surface of the product, the buffer plate compresses the second spring. The second spring exerts a downward force on the ejector block due to the force. At this time, the ejector block transmits the force to the upper slide cylinder and drives the inner surface of the circular slide cylinder of the upper slide cylinder to slide. As the upper slide cylinder slides down, the upper slide cylinder compresses the first spring. As the electric push rod continues to extend, the lifting force of the buffer plate on the product continues to increase. Finally, the buffer plate ejects the product. The above structure can play a certain buffering role on the product surface during the ejection process of the ejection rod, thereby reducing the size of the instantaneous impact force on the product and avoiding the occurrence of local deformation of the product surface due to excessive lifting force.

[0015] The utility model energizes the resistance wire, which releases a large amount of heat. At this time, the resistance wire transmits the surrounding temperature to the control panel. The temperature inside the heating shell can be monitored at any time through the control panel. Utilizing the above structure, the heating condition of the product can be monitored to prevent the surface temperature of the product from being too cold or too hot, resulting in unsatisfactory molding effect.
