Description

Technical Field

[0001] The invention relates to the technical field of mold support, in particular to a supporting and fixing device for a soft glue drop mold. Background Art

[0002] Soft epoxy, with its unique softness and versatility, has become a "universal material" for craft enthusiasts and industrial fields. Through strict temperature control, precise mixing ratio and meticulous degassing, it can achieve a perfect bubble-free and highly transparent effect. The material selection of soft epoxy molds is mainly based on factors such as flexibility, durability, demolding ease and cost. Common materials include silicone. In the process of shaping soft glue, the existing silicone mold is relatively soft, and the side walls of the silicone mold may expand outward under the action of gravity of the glue, causing the edges of the soft glue to thicken or the shape to distort, which can easily affect the molding efficiency of the soft glue. At the same time, when the cooling speed of the soft glue is accelerated by blowing air, the continuous blowing will accelerate the solidification of the glue surface, forming a hard shell, which hinders the volatilization of internal moisture or solvent, causing cracking and blistering, and easily causing ripples on the glue surface, destroying the flatness of the molded soft glue surface. Summary of the Invention

[0003] The technical problems solved by this solution are: (1) How to solve the problem that continuous blowing will accelerate the curing of the glue surface, forming a hard shell, hindering the volatilization of internal moisture or solvent, and easily causing ripples on the glue surface, thereby destroying the surface flatness of the molded soft glue; (2) How to solve the problem that the side wall of the silicone mold expands outward under the action of the gravity of the soft glue, causing the edge of the soft glue to thicken or the shape to distort, which easily affects the molding efficiency of the soft glue.

[0004] The object of the present invention can be achieved by the following technical solution: A supporting and fixing device for a soft drop glue mold, comprising a workbench, two longitudinally arranged positioning plates are fixedly installed on the top of the workbench, a mold is arranged between the two positioning plates, and the front and rear side surfaces of the mold are respectively slidably connected to the two positioning plates, a positioning mechanism for supporting the mold is provided on the top of the workbench, and a drying mechanism for accelerating the molding of the soft drop glue is provided on one side of the positioning mechanism; The drying mechanism includes an adjustment cylinder fixedly connected to the top of the workbench, the top of the adjustment cylinder is connected to a blowing pipe, the output end of the blowing pipe is arranged between the two positioning plates, and an opening is opened at the bottom of the side of the adjustment cylinder.

[0005] A further technical improvement of the present invention is that a support plate is fixedly installed at the bottom of the workbench, a blower and a drive motor are provided on the top of the support plate, the output end of the blower is connected to an air intake pipe, the output end of the air intake pipe passes through the workbench and is connected to the middle and lower part of the adjusting cylinder.

[0006] A further technical improvement of the present invention is that a guide plate is fixedly installed at the bottom of the workbench, a transmission rod is movably inserted on the guide plate, the transmission rod is longitudinally arranged, and the top end of the transmission rod movably passes through the adjustment cylinder and is fixedly installed with a piston.

[0007] A further technical improvement of the present invention is that: a horizontal plate is fixedly installed at the bottom end of the transmission rod, a horizontal groove is provided on the front side of the horizontal plate, a rotating disk is fixedly installed at the output end of the driving motor, a shift lever is fixedly installed on the front side of the rotating disk, and the shift lever is movably connected to the horizontal groove; the mold is heated by turning on the heating pad so that the heat is evenly transferred to the soft glue inside it, and then the extended end of the electric push rod is controlled to extend from the shortest to the longest, so that the baffle is moved to the top of the mold. At this time, there is a gap between the baffle and the mold, and the driving motor is turned on at the same time as the blower. The airflow blown out from the blower is injected into the regulating cylinder along the air inlet pipe, and then blows air between the two positioning plates along the blowing pipe, and carries moisture out through the gap between the baffle and the mold, which is convenient for even heating in conjunction with the heating pad. To dry the soft glue, the driving motor drives the rotating disk, which cooperates with the lever and the cross plate to drive the transmission rod and the piston to move back and forth up and down. When the piston is above the output end of the intake pipe, the airflow entering the adjustment cylinder will be discharged from the opening. When the piston is below the output end of the intake pipe, the airflow will continue to be discharged from the output end of the blowing pipe. Since the output end of the intake pipe is connected to the middle and lower part of the adjusting cylinder, during the operation of the driving motor, the piston is located above the output end of the intake pipe for most of the time, so that the mold is intermittently blown while ensuring that the blowing time is less than the time when the blowing is stopped, to avoid continuous blowing which will accelerate the curing of the glue surface and form a hard shell, hindering the volatilization of internal moisture or solvent, and at the same time prevent the glue surface from generating ripples, which will destroy the flatness of the molded soft glue surface.

[0008] A further technical improvement of the present invention is that the positioning mechanism includes a cylinder fixedly inserted on the top of the workbench, the cylinder is arranged longitudinally, and a lifting plate is fixedly installed on the protruding end of the cylinder, a heating pad for supporting the mold is provided on the top of the lifting plate, and a shielding unit for shielding dust is provided on one side of the cylinder.

[0009] A further technical improvement of the present invention is that a rotating seat is fixedly provided on the workbench on both sides of the cylinder, a clamping frame is rotatably provided on the top of the rotating seat, one end of the clamping frame is fixedly installed with a clamping plate for supporting the side of the mold, and the end of the clamping frame close to the clamping plate is fixedly connected to the workbench through a tension spring.

[0010] A further technical improvement of the present invention is that a lifting frame is fixedly mounted on the protruding end of the cylinder, rollers are rotatably provided at both ends of the lifting frame, and the two rollers are respectively rollingly connected to the ends of the two clamping frames away from the clamping plates.

[0011] A further technical improvement of the present invention is that: the shielding unit includes a fixed plate fixedly connected to the top of the workbench, a laterally arranged electric push rod is fixedly installed on the top of the fixed plate, and the protruding end of the electric push rod is fixedly connected to a laterally arranged shielding plate; by controlling the protruding end of the cylinder to shrink to the shortest, the lifting plate and the heating pad drive the mold to move downward. In this process, the lifting frame cooperates with the two rollers to provide a flipping pressing force to the two clamping frames respectively, so that the two clamping plates provide support for the left and right sides of the mold, and cooperate with the two positioning plates to provide support for the front and back sides of the mold, thereby avoiding the side walls of the mold from expanding outward under the action of gravity of the soft glue, preventing its edges from thickening or distorting in shape, and ensuring the molding efficiency of the soft glue.

[0012] A further technical improvement of the present invention is that: a slide groove is provided on the inner side of the two positioning plates, the size of the shielding plate is larger than the size of the mold, and the front and rear ends of the shielding plate are respectively slidably connected to the two slide grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is in use, the mold is heated by turning on the heating pad so that the heat is evenly transferred to the soft glue inside it, and then the extended end of the electric push rod is controlled to extend from the shortest to the longest, so that the baffle is moved to the top of the mold. At this time, there is a gap between the baffle and the mold, and the drive motor is turned on at the same time as the blower. The air flow blown out from the blower is injected into the adjustment cylinder along the air inlet pipe, and then blows air between the two positioning plates along the blowing pipe, carrying moisture out through the gap between the baffle and the mold. The heating pad is used to facilitate uniform drying of the soft glue, and the driving motor drives the rotating disk, which cooperates with the shift lever and the cross plate to drive the transmission rod and the piston to reciprocate up and down. When the piston is located above the output end of the air intake pipe, the air flow entering the regulating cylinder will be discharged from the opening; when the piston is located below the output end of the air intake pipe, the air flow will continue to be discharged from the output end of the blowing pipe. Since the output end of the air intake pipe is connected with the middle and lower part of the regulating cylinder, during the operation of the driving motor, the piston is located above the output end of the air intake pipe for most of the time, so that the mold can be blown intermittently while ensuring that the blowing time is less than the time of stopping blowing, so as to avoid continuous blowing which will accelerate the solidification of the glue surface and form a hard shell, hinder the volatilization of internal moisture or solvent, and prevent the glue surface from generating ripples and destroying the flatness of the molded soft glue surface.

[0014] When the present invention is in use, the extended end of the cylinder is controlled to shrink to the shortest, so that the lifting plate and the heating pad drive the mold to move downward. During this process, the lifting frame cooperates with the two rollers to provide flipping pressing force to the two clamping frames respectively, so that the two clamping plates provide support for the left and right sides of the mold, and cooperate with the two positioning plates to provide support for the front and back sides of the mold, thereby preventing the side walls of the mold from expanding outward under the action of gravity of the soft glue, preventing its edges from thickening or distorting in shape, and ensuring the molding efficiency of the soft glue.

[0030] Working principle: When the present invention is in use, first, a specified amount of soft glue is injected into the mold 8 through the glue sticking tool 7. At this time, the protruding end of the cylinder 23 is at its longest; by controlling the protruding end of the cylinder 23 to shrink to the shortest, the lifting plate 27 and the heating pad 28 drive the mold 8 to move downward. In this process, the lifting frame 22 cooperates with the two rollers to provide a turning pressing force to the two clamping frames 25 respectively, so that the two clamping plates 26 provide support to the left and right sides of the mold 8, and cooperate with the two positioning plates 1 to provide support to the front and back sides of the mold 8, thereby avoiding the mold The side wall of the mold 8 expands outwards under the action of the gravity of the soft glue, preventing its edge from becoming thicker or distorted in shape, thereby ensuring the molding efficiency of the soft glue; the heating pad 28 is turned on to heat the mold 8 so that the heat is evenly transferred to the soft glue inside it, and then the extended end of the electric push rod 212 is controlled to extend from the shortest to the longest, so that the baffle 211 moves to the top of the mold 8.

When the piston 312 is above the output end of the air inlet pipe 310, the air flow into the regulating cylinder 311 will be discharged from the opening 302. When the piston 312 is below the output end of the air inlet pipe 310, the air flow into the regulating cylinder 311 will be discharged from the opening 302. At this time, the air flow will continue to be discharged from the output end of the blowing pipe 301. Since the output end of the air inlet pipe 310 is connected to the middle and lower part of the adjusting cylinder 311, during the operation of the driving motor 305, for most of the time, the piston 312 is located above the output end of the air inlet pipe 310, so that the mold 8 is blown intermittently while ensuring that the blowing time is less than the time of stopping blowing, avoiding continuous blowing that accelerates the solidification of the glue surface and forms a hard shell, hindering the volatilization of internal moisture or solvent, and preventing the glue surface from generating ripples and destroying the flatness of the molded soft glue surface.
