Description

Technical Field

[0001] The present invention relates to the technical field of corrugated pipe molds, and specifically to a detachable corrugated pipe mold. Background Technique

[0002] With the continuous development of modern society and the gradual improvement of the economic level, the domestic industrial manufacturing level has also achieved remarkable development. In the existing manufacturing production, corrugated pipes, as a common rubber pipe, are often used in fields such as automobiles, electricity, and interior decoration due to their good elasticity and ductility, and easy installation. In the existing corrugated pipe manufacturing technology, in order to ensure the integral molding of corrugated pipes, the method of mold injection molding is often used to manufacture corrugated pipes. At this time, a corrugated pipe mold is required to shape the corrugated pipe before the plastic and rubber are cooled.

[0003] The defects of the corrugated pipe mold in the prior art are as follows:

[0004] 1. The comparative document CN113103472A discloses a detachable corrugated pipe mold. "The present invention discloses a detachable corrugated pipe mold, including a processing bed, a first motor, and a second motor. One side of the bottom end of the inner wall of the first mold block is fixedly connected with a first raised block, the top of the first raised block is fixedly connected with a second raised block, the other side of the bottom end of the inner wall of the first mold block is fixedly connected with a third raised block, the top of the third raised block is fixedly connected with a fourth raised block, and one side of the second raised block is embedded with an embedded slot. The first raised block, the second raised block, the third raised block, and the fourth raised block are respectively installed inside the first mold block, evenly distributed, one above the other. During installation, the embedded slot is installed inside the corrugated pipe mold. During the installation process, the embedded slot is aligned and installed on the four raised blocks, with a clearance fit therebetween, which requires a certain precision, facilitating the rapid disassembly and installation by the staff when making the mold, and is suitable for use in corrugated pipe molds." This corrugated pipe mold lacks a demolding alarm component, resulting in the inability of the user to demold in time when the mold is cooled, leading to low mold utilization rate and thus affecting the production efficiency of the device.

[0005] 2. The existing corrugated pipe molds lack demolding auxiliary components, resulting in a long time often required for mold demolding, affecting the use efficiency of the device. Summary of the Invention

[0006] The purpose of the present invention is to provide a detachable corrugated pipe mold to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present invention provides the following technical solution: A detachable bellows mold, including a top mold plate and a threaded connection buckle. A top mold is installed at the bottom of the top template, and a bottom mold is fitted and connected to the bottom of the top mold; A digital thermometer is installed on the front of the bottom mold, and high-speed flashlights are installed on both sides of the bottom mold, and the high-speed flashlights are electrically connected to the digital thermometer; A bottom template is installed at the bottom of the bottom mold.

[0008] Preferably, a mold core is threaded on the top of the top template, and mold holes are penetrated through the interiors of the top mold and the bottom mold.

[0009] Preferably, a feed hole is penetrated through the top of the top template, and one end of the feed hole extends to one side of the mold hole.

[0010] Preferably, an exhaust hole is installed on the front of the bottom template, and one end of the exhaust hole extends to one side of the mold hole.

[0011] Preferably, four fixing rods are installed on the top of the bottom template, an extension rod is slidably connected inside the fixing rod, a spring is installed on the inner wall of the bottom of the fixing rod, and the top end of the spring extends to the top end of the extension rod.

[0012] Preferably, a number of corrugated rings are arranged on the outer surface of the mold core and the inner wall of the mold hole.

[0013] Preferably, a handle is installed on the top of the mold core, and two threaded connection buckles are installed on the top of the top template, and the threaded connection buckles are located outside the mold core.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. By installing a digital thermometer and high-speed flashlights, the digital thermometer is powered by the battery inside after being turned on, and the temperature of the bottom mold is detected. When the temperature inside the bottom mold reaches the appropriate temperature, the digital thermometer transmits the current to the inside of the high-speed flashlight. When the current is conducted from the digital thermometer to the inside of the high-speed flashlight, the high-speed flashlight is powered on to drive the filament inside to emit light, and flashes to remind the user that demolding can be performed, thereby improving the use efficiency of the device.

[0016] 2. By installing an extension rod and a spring, when the top template receives the pressure from an external stamping device, the top template moves downward, generating pressure on the extension rod. At this time, the spring contracts to convert the pressure into elastic potential energy and store it inside. When the external pressure disappears, the spring converts the elastic potential energy into kinetic energy and conducts it to the inside of the extension rod. At this time, the kinetic energy of the extension rod drives the spring to move upward, generating a thrust on the top template, causing a gap between the top mold and the bottom mold, facilitating the demolding of the bellows, and improving the use efficiency of the device.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the present invention: a detachable corrugated pipe mold.

[0025] Embodiment 1 includes a top template 1 and a threaded connection buckle 16. A top mold 2 is installed at the bottom of the top template 1. The top template 1 provides fixing points for the top mold 2, the mold core 7, the feed hole 9 and the threaded connection buckle 16 installed on its outer surface and inside. The top mold 2 is connected in an inlaid manner with the bottom mold 3 to provide a fixing point for the mold hole 8 opened through the inner side thereof. The bottom of the top mold 2 is connected in an inlaid manner with the bottom mold 3; the top mold 2 is connected in an inlaid manner with the top mold 2 to provide a fixing point for the mold hole 8 opened through the inner side thereof, and at the same time provides a fixing point for the digital temperature gauge 4 and the high-speed flash light 5 installed on its outer surface. The bottom of the bottom mold 3 The bottom of the mold 1 is provided with a bottom template 6, which provides a fixing point for the bottom mold 3 and the fixing rod 11 installed on the top thereof, and provides support for the whole device. The top thread of the top mold 1 is provided with a mold core 7. Before the molten plastic needs to be injected, the mold core 7 is rotated and inserted into the interior of the top mold 1, and the mold core 7 is inserted into the interior of the mold hole 8. The interiors of the top mold 2 and the bottom mold 3 are penetrated with mold holes 8, and a corrugated ring 14 is arranged inside thereof to provide a fixing point. When the molten plastic enters the interior thereof through the feed hole 9, the insertion of the mold core 7 forms a tubular gap inside the mold hole 8, so that the molten plastic can be tubular in the mold hole 8. The top of the top template 1 is provided with a feed hole 9, and one end of the feed hole 9 extends to one side of the mold hole 8. When molten plastic needs to be injected, one end of the external plastic conveying device is inserted into the inside thereof, and under the pressure of the external plastic conveying device, the molten plastic is squeezed into the inside of the mold hole 8 through the feed hole 9. The front of the bottom template 6 is provided with an exhaust hole 10, and one end of the exhaust hole 10 extends to one side of the mold hole 8. When the molten plastic enters the inside of the mold hole 8 through the feed hole 9, the gas inside the mold hole 8 is discharged through the exhaust hole 10 under the pressure of the molten plastic, thereby preventing Honeycomb bubbles appear after the bellows is formed. A number of corrugated rings 14 are arranged on the outer surface of the mold core 7 and the inner wall of the mold hole 8. The corrugated rings 14 are arranged on the outer surface of the mold core 7 and the inner side of the mold hole 8 so that the molten plastic can be cooled and formed along the shape of the corrugated rings 14, so that the pipe presents a corrugated shape. A handle 15 is installed on the top of the mold core 7 to provide a fulcrum for the installation and disassembly of the mold core 7. Two sets of threaded connectors 16 are installed on the top of the top template 1, and the threaded connectors 16 are located on the outside of the mold core 7. When the mold needs to be pressurized, it can be connected to an external pressure delivery device via the threaded connectors 16 to extrude the entire mold.

[0026] As attached Figure 1 As shown, a detachable bellows mold,

[0027] Embodiment 2 includes a bottom mold 3 and a high-speed flash light 5. A digital thermometer 4 is installed on the front of the bottom mold 3. The digital thermometer 4 is powered by an internal battery to detect the temperature of the bottom mold 3. When the temperature inside the bottom mold 3 reaches room temperature, the digital thermometer 4 transmits current to the inside of the high-speed flash light 5. High-speed flash lights 5 are installed on both sides of the bottom mold 3, and the high-speed flash light 5 is electrically connected to the digital thermometer 4. When the current is transmitted to the inside of the high-speed flash light 5 through the digital thermometer 4, the high-speed flash light 5 is energized to drive the internal filament to emit light, and flash to remind the user that the mold can be demolded, thereby improving the use efficiency of the device.

[0028] As attached Figure 1 , Figure 4 and Figure 5 As shown, a detachable bellows mold,

[0029] Embodiment three includes a bottom template 6 and a fixed rod 11. Four groups of fixed rods 11 are installed on the top of the bottom template 6 to provide fixed points for the extension rod 12 and spring 13 slidably connected thereto. The extension rod 12 is slidably connected to the inside of the fixed rod 11. When the top of the extension rod 12 receives pressure, the extension rod 12 contracts and transmits the pressure to the inside of the spring 13. When the pressure disappears, the extension rod 12 moves upward driven by the kinetic energy of the spring 13, generating a thrust on the top template 1, so that a gap is generated between the top mold 2 and the bottom mold 3, facilitating the demoulding of the bellows and improving the efficiency of the device. A spring 13 is installed on the inner wall of the bottom of the fixed rod 11, and the top of the spring 13 extends to the top of the extension rod 12. When the top template 1 receives pressure from an external stamping device, the top template 1 moves downward and generates pressure on the extension rod 12. At this time, the spring 13 contracts to convert the pressure into elastic potential energy. When the external pressure disappears, the spring 13 converts the elastic potential energy into kinetic energy and transmits it to the inside of the extension rod 12.

[0030] Working principle: First, rotate the mold core 7 and insert it into the interior of the top template 1, insert the mold core 7 into the interior of the mold hole 8, and then connect it to the external pressure conveying device via the threaded connection buckle 16, and then insert one end of the external plastic conveying device into it, and under the pressure of the external plastic conveying device, squeeze the molten plastic into the interior of the mold hole 8 through the feed hole 9. When the molten plastic enters the interior through the feed hole 9, a tubular gap is formed inside the mold hole 8 due to the insertion of the mold core 7, so that the molten plastic can be cooled in a tubular shape inside the mold hole 8. At the same time, when the molten plastic enters the interior of the mold hole 8 through the feed hole 9, the gas inside the mold hole 8 is discharged through the exhaust hole 10 under the pressure of the molten plastic, so as to prevent the formation of honeycomb bubbles after the bellows is formed.
