Description
Technical Field
[0001] This utility model relates to the field of press technology, and in particular to a mold changing device for a valve press. Background Technology
[0002] Valve presses utilize high-pressure gas generated by a compressor, which is then transported through pipelines to a solenoid valve. The operation of the solenoid valve is controlled by a switch, thereby controlling the operation and return of the cylinder to achieve the purpose of pressing. In existing valve presses, the pressing module will wear out after long-term use and needs to be replaced.
[0003] The patent titled "A Mold Changing Structure for a Press" (patent application number: 202321683116.0) discloses a mold changing structure for a press, including a base plate. A telescopic cylinder is arranged above the base plate, and a connecting block is fixedly installed at the lower end of the telescopic cylinder. Two bolts pass through the upper end of the connecting block, and a pressing module is arranged at the lower end of the connecting block. Sliding grooves are opened at both the front and rear ends of the base plate. A rectangular groove is opened at the bottom of the inner end of the sliding groove. Vertical blocks are arranged outside the sliding grooves. A support plate is fixedly installed between two vertical blocks. Electric telescopic columns are fixedly installed near the four corners of the upper end of the support plate, and a top plate is fixedly installed on the top of the electric telescopic columns. This structure enables rapid mold changing.
[0004] In the above case, during the mold changing process of the pressure module, the operator needs to move the top plate back and forth to ensure that the long block on the top of the pressure module is inserted into the groove and the pressure module is fixed. This process is time-consuming and not conducive to the rapid connection of the pressure module. Furthermore, when the telescopic cylinder moves the pressure module downward to press the object, the reverse force on bolt two is too large. Over time, bolt two may break, causing inconvenience to the use of the press. Therefore, it is necessary to propose a mold changing device for a valve press to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a valve press mold changing device to solve the problem mentioned in the background art, which requires the operator to move the top plate back and forth to determine whether the long block on the top of the pressing module is inserted into the groove to fix the pressing module. This process is time-consuming and not conducive to the rapid connection of the pressing module. Moreover, when the telescopic cylinder drives the pressing module to move downward to press the object, the reverse force on its second bolt is too large. Over time, the second bolt may break, which brings inconvenience to the use of the press.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve press mold changing device, including a base and a valve press telescopic arm, a connecting block is fixedly connected to the bottom of the valve press telescopic arm, a T-shaped groove is provided inside the connecting block, a T-shaped slider is slidably connected inside the T-shaped groove, and a pressure module is fixedly connected to the bottom of the T-shaped slider.
[0007] A movable plate is slidably connected to the top of the base, and a mold changing assembly is provided on the top of the movable plate. The mold changing assembly includes an electric push rod and a lifting block. The bottom of the electric push rod is fixedly connected to the top of the movable plate, and the telescopic end of the electric push rod is fixedly connected to the bottom of the lifting block. A mold placement groove is provided inside the lifting block.
[0008] Preferably, there are three T-slots and three T-slides, and there is a one-to-one correspondence between the T-slots and the T-slides.
[0009] Preferably, the mold placement groove is adapted to the mold module;
[0010] The number of electric push rods is two, and the two electric push rods are symmetrically distributed on the top of the moving plate.
[0011] Preferably, the T-shaped slider has screw holes on its side, and a fixing bolt is inserted into the outside of the connecting block, with the fixing bolt and the screw hole being compatible.
[0012] Preferably, a sliding assembly is provided on the outside of the movable plate. The sliding assembly includes a connecting plate and a movable block. The outside of the connecting plate is fixedly connected to the outside of the movable plate, and the outside of the connecting plate is fixedly connected to the outside of the movable block.
[0013] The movable plate has a sliding groove on its outside, and the outside of the movable block is slidably connected to the inside of the sliding groove.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] By configuring a base, valve press telescopic arm, connecting block, fixing bolts, T-slot, T-slider, pressure module, moving plate, connecting plate, electric push rod, lifting block, and pressure mold placement slot, when it is necessary to change the film on the pressure module, first place the pressure module inside the pressure mold placement slot so that the top of the pressure module is at the same level as the top of the lifting block. Then push the lifting block so that it is below the connecting block. At this time, the electric push rod can be opened, which will drive the lifting block to move upward, so that the top of the lifting block contacts the bottom of the connecting block. At this point, the lifting block can be pushed further to quickly insert the T-shaped slider into the T-slot. Then, the T-shaped slider is fixed in place using the fixing bolts. This process is simple and does not require correction of the pressure module's position, allowing for quick film replacement. Furthermore, due to the design of the T-slot and T-shaped slider, when the valve press's telescopic arm moves the pressure module downward to press the object, the two sides of the T-shaped slider can distribute the reaction force, preventing it from acting directly on the fixing bolts and thus avoiding the problem of the fixing bolts breaking after a long period of time. This brings convenience to the use of the press. Attached Figure Description

There are three T-shaped grooves 5 and three T-shaped sliders 6, and each T-shaped groove 5 and T-shaped slider 6 corresponds to another T-shaped slider 6. Screw holes 8 are formed on the side of the T-shaped slider 6, and fixing bolts 4 are inserted into the outside of the connecting block 3. The fixing bolts 4 and screw holes 8 are compatible, and the fixing bolts 4 can be used to easily fix the pressure module 7, which brings convenience to the fixing of the pressure module 7. Due to the design of the T-shaped groove 5 and T-shaped slider 6, when the valve press telescopic arm 2 moves the pressure module 7 downward to press the object, the two sides of the T-shaped slider 6 can distribute the reaction force, avoiding direct action on the fixing bolt 4, which is prone to breakage after a long time. This brings convenience to the use of the press.
[0023] In addition, a movable plate 9 is slidably connected to the top of the base 1. A mold changing assembly is provided on the top of the movable plate 9. The mold changing assembly includes an electric push rod 13 and a lifting block 14.

A sliding groove 12 is provided on the outside of the movable plate 9, and the outside of the movable block 11 is slidably connected to the inside of the sliding groove 12. When it is necessary to change the film on the pressure module 7, first, the pressure module 7 is placed inside the mold placement groove 15, so that the top of the pressure module 7 is at the same level as the top of the lifting block 14. Then, the lifting block 14 is pushed so that it is below the connecting block 3. At this time, the electric push rod 13 can be opened, which will drive the lifting block 14 to move upward, so that the top of the lifting block 14 contacts the bottom of the connecting block 3. Then, the lifting block 14 can be pushed further to quickly insert the T-shaped slider 6 into the T-shaped groove 5. The T-shaped slider 6 is then fixed in place by the fixing bolt 4. This process is simple and can quickly complete the film change without the need to correct the position of the pressure module 7.
[0025] Working principle: When it is necessary to change the film on the pressure module 7, first place the pressure module 7 into the mold placement slot 15 so that the top of the pressure module 7 is at the same level as the top of the lifting block 14. Then push the lifting block 14 so that the lifting block 14 is below the connecting block 3. At this time, the electric push rod 13 can be opened.
