Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of opening and closing mechanisms, specifically a mold detection opening and closing mechanism. Background Technology
[0002] The mold opening and closing mechanism is an important component of the mold structure. It is mainly responsible for the opening and closing of the mold and for detecting the mold status during this process. In molding processes such as injection molding and die casting, the opening and closing mechanism can accurately separate (open) and close (close) the moving mold and the fixed mold. For example, in injection molds, after the injection process is completed, the opening and closing mechanism drives the moving mold to retract, so that the product can be easily demolded; and when the mold is closed, it can accurately close the moving mold and the fixed mold to ensure the sealing of the cavity and prepare for the next injection.
[0003] Most existing opening and closing mechanisms use sensors installed on the mold to determine whether the mold is fully open or closed. If the mold needs to be replaced due to damage, the internal sensors need to be disassembled and reinstalled on the new mold, which is time-consuming and labor-intensive. Furthermore, damage to the mold can easily affect the use of the sensors. Therefore, it is necessary to propose a mold detection opening and closing mechanism. Utility Model Content
[0004] The purpose of this invention is to provide a mold detection opening and closing mechanism to solve the problems mentioned in the background art.

A fixed base is fixedly connected to the output end of the hydraulic push rod. A plug is movably connected inside the fixed base. A bolt is movably connected to one side of the fixed base. A nut is movably connected to the outer wall of the bolt. The first mold is fixedly connected to one side of the plug. A top plate is fixedly connected to one side of the vertical plate. A light source is fixedly connected to one side of the fixed base. A fixed plate is fixedly connected to the front of the workbench. A light receiver is fixedly connected to one side of the fixed plate. A push rod is fixedly connected to one side of the first mold. A protective pad is fixedly connected to one end of the push rod.
[0007] Preferably, a second mold is movably connected above the workbench, a switch is fixedly connected inside the fixed base, and a bell is fixedly connected above the fixed base.
[0008] Preferably, the fixing base has a slot inside, and the shape and size of the slot match the shape and size of the insert.

[0010] Preferably, the sliding mechanism includes a groove, a connecting plate, and rollers. The groove is provided inside the worktable, the connecting plate is fixedly connected to the lower part of the first mold, and the rollers are movably connected inside the connecting plate.
[0011] Preferably, the roller passes through the interior of the connecting plate and extends into the interior of the trough, and the roller is movably connected to the connecting plate and the trough.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This mold detection opening and closing mechanism, in conjunction with a detection mechanism, involves activating a hydraulic push rod during operation to move the positions of the first and second molds, thereby closing them. At this time, a push rod and protective pad on one side of the first mold insert into a switch inside a fixed base on one side of the second mold, actuating the switch and triggering a bell. This indicates that the first and second molds are fully closed. If the bell does not ring, the mold closure is unstable. When the hydraulic push rod moves the first and second molds away from each other to their initial state, the position of the light source aligns with that of the light receiver, causing a change in the light intensity received by the receiver, generating a corresponding electrical signal, which is then transmitted to the controller. The controller then initiates the next action. If they do not align, the next action cannot be initiated. Furthermore, when replacing the first and second molds, there is no need to disassemble and install the corresponding detection equipment, thus improving the practicality of the opening and closing mechanism.
[0014] 2. The mold detection opening and closing mechanism, through the setting of the sliding mechanism, and the connection of the connecting plate during the use of the opening and closing mechanism, enables the first mold and the second mold to move synchronously, driving the rollers to roll inside the groove, reducing the resistance of the first mold and the second mold during the opening and closing process, indirectly improving the smoothness and efficiency of the injection molding work, thereby improving the applicability of the opening and closing mechanism to a certain extent.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 The present invention provides a technical solution: a mold detection opening and closing mechanism, including a workbench 1, a guide groove 2 is provided inside the workbench 1, a detection mechanism 3 is fixedly connected above the workbench 1, and a sliding mechanism 4 is movably connected inside the workbench 1.
[0022] The testing mechanism 3 includes a vertical plate 301, a hydraulic push rod 302, a fixed base 303, a plug 304, a bolt 305, a nut 306, a first mold 307, a top plate 308, a light source 309, a fixed plate 310, a light receiver 311, a push rod 312, a protective pad 313, a second mold 314, a switch 315, and a bell 316. The vertical plate 301 is fixedly connected to the top of the workbench 1, and a hydraulic push rod 302 is fixedly connected to one side of the vertical plate 301. The output end of 2 is fixedly connected to a mounting base 303. The mounting base 303 has an internal slot, the shape and size of which match the shape and size of the insert block 304, facilitating the loading and unloading of the first mold 307 and the second mold 314 from the mounting base 303, and making it easy to replace the first mold 307 and the second mold 314. The insert block 304 is movably connected inside the mounting base 303, and a bolt 305 is movably connected to one side of the mounting base 303, passing through the insert block 304. The bolt 305 extends into the interior of the fixed base 303 and extends to both sides of the fixed base 303. The bolt 305 is movably connected to the insert block 304 and the fixed base 303, which improves the stability of the first mold 307 and the second mold 314 when installed with the fixed base 303. At the same time, it is convenient to disassemble and replace the first mold 307 and the second mold 314. The outer wall of the bolt 305 is movably connected to the nut 306. The first mold 307 is fixedly connected to one side of the insert block 304. The top plate 308 is fixedly connected to one side of the upright plate 301. The light source 309 is fixedly connected to one side of the fixed base 303. The front of the worktable 1 is fixedly connected to the fixed plate 310. The light receiver 311 is fixedly connected to one side of the fixed plate 310. The top rod 312 is fixedly connected to one side of the first mold 307. The protective pad 313 is fixedly connected to one end of the top rod 312. The second mold 314 is movably connected to the top of the worktable 1. The switch 315 is fixedly connected inside the fixed base 303. The bell 316 is fixedly connected to the top of the fixed base 303.
[0023] Please see Figure 1-4 The sliding mechanism 4 includes a groove 401, a connecting plate 402, and a roller 403. The groove 401 is provided inside the worktable 1. The connecting plate 402 is fixedly connected to the lower part of the first mold 307. The roller 403 is movably connected inside the connecting plate 402. The roller 403 passes through the interior of the connecting plate 402 and extends into the interior of the groove 401. The roller 403 is movably connected to the connecting plate 402 and the groove 401, which reduces the resistance when the first mold 307 and the second mold 314 move, and indirectly improves the efficiency of injection molding.
[0024] Working principle: When using this mold to test the opening and closing mechanism, firstly, the hydraulic push rod 302 is activated, driving the first mold 307 and the second mold 314 to move. Through the connection plate 402, the first mold 307 and the second mold 314 move, causing the roller 403 to roll synchronously inside the groove 401, reducing the resistance during their movement and thus closing the first mold 307 and the second mold 314. At this time, the push rod 312 on one side of the first mold 307 and the protective... The pad 313 inserts into the switch 315 inside the fixing seat 303 on one side of the second mold 314, actuating the switch 315 and triggering the bell 316 to sound. This indicates that the first mold 307 and the second mold 314 are fully closed. If the bell 316 does not sound, there is an unstable factor in the closure of the first mold 307 and the second mold 314. When it is necessary to demold the injection molded part, the hydraulic push rod 302 is activated, which moves the first mold 307 and the second mold 314 away from each other to their initial state. The top plate 308 then engages with the first mold 307 and the second mold 314. The internal injection mold 314 is pushed to allow the injection molded part to be discharged through the guide groove 2. When the first mold 307 and the second mold 314 return to their initial positions, the position of the light source 309 will correspond to that of the light receiver 311. The light intensity received by the light receiver 311 will then change, generating a corresponding electrical signal. This electrical signal is usually quite weak and needs to be processed by signal processing circuits such as amplification and filtering before being transmitted to the controller. The controller then initiates the next action. If there is no correspondence, the next action cannot be started, such as in the case of the first mold 307. When the first mold 307 and the second mold 314 are damaged and need to be replaced, unscrew the nut 306 from the outer wall of the bolt 305, then unscrew the bolt 305 from the inside of the fixing seat 303, and then pull the first mold 307 and the second mold 314 upwards, causing the insert block 304 to disengage from the fixing seat 303, thus achieving the disassembly of the first mold 307 and the second mold 314. At the same time, there is no need to disassemble and install the light source 309, the light receiver 311, the switch 315 and the bell 316. In this way, the use process of the mold detection opening and closing mechanism is completed.
