Description

Technical Field

[0001] This invention relates to the field of glass product technology, specifically to a glass product pressing mold and method. Background Technology

[0002] In glass production, pressing and shaping are required, typically accomplished using molding dies. Chinese patent CN220034315U discloses a glass pressing and shaping die, where a pressure plate and a material-taking mechanism each correspond to a mold cavity. During the pressing process, the material is adsorbed. While this patent improves work efficiency, the adsorbed shaped glass products require further transfer during operation. However, the constantly rotating and repositioning material-taking plate cannot transfer the shaped glass products to a fixed position, increasing the difficulty of the transfer process. Summary of the Invention

[0003] The purpose of this invention is to provide a glass product pressing mold and method, which involves flipping the lower mold and then ejecting the product through an ejector, facilitating collection or further processing, and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a glass product pressing mold, comprising a fixed plate, a guide sleeve fixedly connected to the upper end of the fixed plate, a pressure plate assembly and a movable frame movably connected inside the guide sleeve, the pressure plate assembly and the movable frame being sleeved together, a support base fixedly connected to the lower end of the fixed plate, a template assembly movably connected inside the support base, and the template assembly being movably connected to the movable frame.

[0005] Preferably, the pressure plate assembly includes a connecting plate, an upper template, and a driving cylinder. The driving cylinder is fixedly connected to the upper surface of the guide sleeve, and the output end of the driving cylinder passes through the guide sleeve. One end of the driving cylinder placed inside the guide sleeve is fixedly connected to the connecting plate. The connecting plate is sleeved with the guide sleeve. The lower end of the connecting plate extends to the outside of the guide sleeve, and the lower end of the connecting plate is connected to the upper template.

[0006] Preferably, the connecting plate has a long sliding groove, and the side wall of the connecting plate has an inclined sliding groove. The movable frame passes through the long sliding groove and is movably connected to the inclined sliding groove.

[0007] Preferably, the guide sleeve has symmetrically provided limit grooves on both sides near the bottom, and rectangular holes are symmetrically provided at both ends near the bottom of the guide sleeve.

[0008] Preferably, the movable frame includes a crossbar, a pull plate, and a movable column. The two ends of the crossbar are fixedly connected to symmetrically arranged pull plates, and the lower end of the pull plate is fixedly connected to the movable column. The crossbar passes through both a long slide groove and a rectangular hole. Limiting blocks are symmetrically arranged on both sides of the crossbar, and the limiting blocks are movably connected to the inclined slide groove and the limiting slide groove.

[0009] Preferably, the template assembly includes a lower mold, a control sleeve, and an ejector. The lower surface of the lower mold is fixedly connected to the control sleeve, which is sleeved with the movable column. The end of the control sleeve is movably connected to the support base, and the lower mold is movably connected to the ejector.

[0010] Preferably, limit balls are symmetrically arranged on the inner wall of the control sleeve, and a protruding ring is provided at the end of the control sleeve, which is movably connected to the support seat through a bearing.

[0011] Preferably, the surface of the movable column is symmetrically provided with a first straight groove, an arc-shaped groove and a second straight groove connected in sequence, and the first straight groove, the arc-shaped groove and the second straight groove are all matched with the limiting ball.

A tension spring is sleeved on the ejector column, and both ends of the tension spring are fixedly connected to the lower mold and the counterweight, respectively.

[0013] Another technical problem to be solved by the present invention is to provide a method for using a glass product pressing mold, comprising the following steps:

[0014] S1: Initial state, the lower mold opening faces upward, glass material is injected into the lower mold, the drive cylinder drives the connecting plate to move downward, and controls the upper mold to press the glass material;

[0015] S2: The drive cylinder drives the upper template to separate from the lower mold. The movable frame moves with the upper template, causing the lower mold to flip. The ejector pushes out the formed glass product.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To address the issue that existing adsorption-based molding glass products require further transfer, but the constantly rotating and repositioning pick-up plate cannot transport the molded glass products to a fixed position, increasing the difficulty of transfer, please refer to [the relevant documentation / reference needed]. Figures 1-7 This embodiment provides the following technical solution:

[0029] In this embodiment, the glass product pressing mold includes a fixed plate 1. A guide sleeve 11 is fixedly connected to the upper end of the fixed plate 1. A pressure plate assembly 2 and a movable frame 3 are movably connected inside the guide sleeve 11. The pressure plate assembly 2 moves up and down along the guide sleeve 11, and the movable frame 3 moves horizontally within the guide sleeve 11. The pressure plate assembly 2 and the movable frame 3 are sleeved together, and the pressure plate assembly 2 drives the movable frame 3 to move. A support base 12 is fixedly connected to the lower end of the fixed plate 1. A template assembly 4 is movably connected inside the support base 12. The template assembly 4 is movably connected to the movable frame 3, and the movable frame 3 drives the template assembly 4 to flip.

[0030] In this embodiment, the pressure plate assembly 2 includes a connecting plate 21, an upper template 22, and a driving cylinder 23. The driving cylinder 23 is fixedly connected to the upper surface of the guide sleeve 11, and the output end of the driving cylinder 23 passes through the guide sleeve 11. One end of the driving cylinder 23 placed inside the guide sleeve 11 is fixedly connected to the connecting plate 21. The driving cylinder 23 drives the connecting plate 21 to move up or down, and the connecting plate 21 is sleeved with the guide sleeve 11. The outer wall of the connecting plate 21 fits against the guide sleeve 11, and the guide sleeve 11 guides the connecting plate 21. The lower end of the connecting plate 21 extends to the outside of the guide sleeve 11, and the lower end of the connecting plate 21 is connected to the upper template 22. The connecting plate 21 drives the upper template 22 to move up or down. Moving up opens the mold, and moving down closes the mold, thus pressing and forming the glass material.

[0031] In this embodiment, a long slide groove 211 is provided on the connecting plate 21, and an inclined slide groove 212 is provided on the side wall of the connecting plate 21. The movable frame 3 passes through the long slide groove 211 and is movably connected to the inclined slide groove 212. The long slide groove 211 provides the movable frame 3 with a space for movement, while the inclined slide groove 212 restricts the movement path of the movable frame 3.

[0032] In this embodiment, the guide sleeve 11 is symmetrically provided with limiting grooves 111 on both sides near the bottom, and rectangular holes 112 are symmetrically opened at both ends near the bottom of the guide sleeve 11. The lower end of the guide sleeve 11 is an open structure, and the connecting plate 21 extends in and out of the guide sleeve 11.

[0033] In this embodiment, the movable frame 3 includes a crossbar 31, a pull plate 32, and a movable column 33. The two ends of the crossbar 31 are fixedly connected to symmetrically arranged pull plates 32. The lower end of the pull plate 32 is fixedly connected to the movable column 33. The crossbar 31 passes through both the long slide groove 211 and the rectangular hole 112. Limiting blocks 311 are symmetrically arranged on both sides of the crossbar 31. The limiting blocks 311 are movably connected to the inclined slide groove 212 and the limiting slide groove 111. Under the restriction of the limiting slide groove 111 and the rectangular hole 112, the crossbar 31 can only move horizontally, which drives the pull plate 32 to move horizontally, thereby controlling the moving position of the movable column 33.

[0034] In this embodiment, the template assembly 4 includes a lower mold 41, a control sleeve 42, and an ejector 43. The lower surface of the lower mold 41 is fixedly connected to the control sleeve 42, which is sleeved with the moving column 33. The end of the control sleeve 42 is movably connected to the support base 12. The lower mold 41 is movably connected to the ejector 43. The support base 12 restricts the position of the control sleeve 42 to prevent it from moving. The moving column 33 drives the control sleeve 42 to rotate, thereby controlling the lower mold 41 to flip. A conveyor belt is provided between the lower ends of the support base 12. Glass products that fall after the lower mold 41 flips are caught by the conveyor belt and transported.

[0035] In this embodiment, limit balls 421 are symmetrically arranged on the inner wall of the control sleeve 42. The limit balls 421 are used to limit the position of the control sleeve 42 and position the control sleeve 42. A protruding ring 422 is provided at the end of the control sleeve 42. The protruding ring 422 is movably connected to the support seat 12 through a bearing. The support seat 12 supports the control sleeve 42, and the protruding ring 422 rotates on the support seat 12.

[0036] In this embodiment, the surface of the movable column 33 is symmetrically provided with a first straight groove 331, an arc-shaped groove 332, and a second straight groove 333 connected in sequence. The first straight groove 331, the arc-shaped groove 332, and the second straight groove 333 all match the limiting ball 421. When the first straight groove 331 is engaged with the limiting ball 421, the control sleeve 42 drives the lower mold 41 to open upward. When the arc-shaped groove 332 is engaged with the limiting ball 421, the limiting ball 421 moves along the arc-shaped groove 332. The control sleeve 42 rotates, and the limiting ball 421 moves from one end of the arc groove 332 to the other end, just enough to rotate the control sleeve 42 180°. When the second straight groove 333 engages with the limiting ball 421, the control sleeve 42 causes the lower mold 41 to open downwards, pouring out the formed glass. The length of the first straight groove 331 is longer than that of the second straight groove 333. The limiting ball 421 moves a longer distance in the first straight groove 331, which can provide injection time for the lower mold 41.

[0037] In this embodiment, the ejector 43 includes an ejector pin 431, a conical block 432, a tension spring 433, and a counterweight 434. The ejector pin 431 penetrates the bottom of the lower mold 41. One end of the ejector pin 431, which is located inside the ejector pin 431, is fixedly connected to the conical block 432. The lower mold 41 has an ejection hole 411 that matches the ejector pin 431 and the conical block 432. The lower end of the ejector pin 431 is fixedly connected to the counterweight 434. A tension spring 433 is sleeved on the ejector pin 431. The two ends of the tension spring 433 are respectively connected to the lower mold 41. The mold 41 and the counterweight 434 are fixedly connected. When the opening of the lower mold 41 faces upward, the counterweight 434 drives the top column 431 and the conical block 432 to move downward. The tension spring 433 is stretched, and the conical block 432 blocks the ejection hole 411, injecting glass material into the lower mold 41. When the opening of the lower mold 41 faces downward, the counterweight 434 pushes the top column 431, and the formed glass is ejected from the lower mold 41 through the conical block 432. The tension spring 433 pulls the counterweight 434 downward under the action of elasticity, accelerating the ejection of the formed glass.

[0038] To better illustrate the usage process of glass product pressing and forming molds, this embodiment presents a method for using glass product pressing and forming molds, including the following steps:

[0039] Step 1: In the initial state, the lower mold 41 is open and facing upward. Glass material is injected into the lower mold 41. The drive cylinder 23 drives the connecting plate 21 to move downward. The upper mold plate 22 is controlled to press the glass material. The inclined slide 212 pushes the limit block 311 to move. The crossbar 31 moves horizontally in the rectangular hole 112. The pull plate 32 and the moving column 33 move at the same time. At this time, the limit ball 421 is engaged with the first straight groove 331. The lower mold 41 keeps its opening facing upward.

[0040] Step 2: The upper template 22 moves to engage with the lower mold 41 to press the glass material. After the glass material cools and solidifies, the drive cylinder 23 drives the upper template 22 to separate from the lower mold 41. The movable frame 3 moves with the upper template 22, causing the lower mold 41 to flip. The lower mold 41 remains stationary. When the limit ball 421 moves into the arc groove 332, the lower mold 41 rotates under the drive of the control sleeve 42. The lower mold 41 rotates until the opening faces downward. The limit ball 421 moves to the second straight groove 333. The ejector 43 ejects the formed glass product. The counterweight 434 moves downward under its own weight and the pull of the tension spring 433, pushing the formed glass product in the lower mold 41 to detach from the lower mold 41.

[0041] Step 3: Drive cylinder 23 again moves the upper template 22 down, and the lower mold 41 flips up so that the opening faces upward. Repeat step 1.

[0042] In summary, a connecting plate 21 is set on the upper template 22, and the connecting plate 21 is movably connected to the movable frame 3. The movable frame 3 is driven to move horizontally by the inclined slide 212, and then the control sleeve 42 is rotated by the moving column 33 to adjust the opening position of the lower mold 41. The opening faces upward for material injection and pressing. After pressing, it moves upward with the upper template 22, the lower mold 41 is rotated, and the ejector 43 completes the ejection work. The whole process is sequential and synchronous, saving transfer time. The ejected glass products fall into a fixed position for easy collection or to proceed to the next process.
