Description

Technical Field

[0001] This utility model relates to a forming mold for processing crystal products, and in particular a crystal processing mold with push-out and pull-back functions. Background Technology

[0002] In the processing of crystal products, in order to give the crystal surface different textures or shapes, the crystal raw material needs to be heated and softened first. Then, the softened crystal raw material is placed into a mold, and the crystal raw material can be shaped by using external pressure equipment. During the shaping process, the mold is required. In the past, the molds were mostly made of heat-resistant hard materials. After the crystal is shaped, it is almost in close contact with the side wall of the mold. Moreover, the surface temperature of the crystal is high for a period of time after it is shaped. As a result, the demolding process not only requires the use of external demolding tools, but also requires constant adjustment of the mold position, resulting in low overall demolding efficiency.

[0003] To facilitate subsequent demolding, many manufacturers employ a split-mold structure, as disclosed in patent number "CN201721779584.2". This split-mold structure, combined with an external ejection device, increases the gap between the mold and the formed crystal during demolding, making it easier to remove the crystal and improving demolding efficiency. However, in actual use, this type of mold requires manual repositioning after ejection and readjustment to the external ejection device, making overall operation inconvenient. Therefore, designing a crystal molding mold that ensures both demolding efficiency and ease of operation has become an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a crystal processing mold with push-out and pull-back functions. This invention has the advantage of being easy to use.

[0005] The technical solution of this utility model: a crystal processing mold with push-out and pull-back functions, including an open-shaped outer shell and multiple mold blocks, each mold block being slidably connected inside the outer shell, and a push-pull component being provided on the inner bottom surface of the outer shell, the push-pull component being slidably engaged with the bottom end of all the mold blocks; the push-pull component simultaneously pushes all the mold blocks out of the outer shell and pulls them back into the outer shell.

[0006] In the aforementioned crystal processing mold with push-out and pull-back functions, the push-pull component includes a push rod, the top of which is provided with a chuck; each mold block is provided with a slot, which slides and engages with the chuck.

[0007] In the aforementioned crystal processing mold with push-out and pull-back functions, a stop member is provided on the side of the chuck, and the stop member is set in the chuck groove; when the push rod pushes all the mold blocks out of the outer shell and pulls back the outer shell through the chuck, the stop member is always located in the chuck groove.

[0008] In the aforementioned crystal processing mold with push-out and pull-back functions, the mold block includes a bottom mold block, an end face mold block, and two symmetrically distributed side mold blocks. The end face mold block and the two side mold blocks are arranged in a ring on the outer circumference of the bottom mold block. Each side mold block has a threaded groove on its side facing the bottom mold block. The threaded groove is semi-threaded.

[0009] In the aforementioned crystal processing mold with push-out and pull-back functions, each of the side mold blocks is provided with a water ripple groove on the side facing the bottom mold block, and the water ripple groove is located between the thread groove and the end face mold block.

[0010] In the aforementioned crystal processing mold with push-out and pull-back functions, a groove is provided on the top surface of the outer shell at the position corresponding to the middle of the side mold block; a recessed area flush with the groove is provided on the top surface of the side mold block.

[0011] In the aforementioned crystal processing mold with push-out and pull-back functions, the side of the side mold block away from the end face mold block is a vertical surface.

[0012] In the aforementioned crystal processing mold with push-out and pull-back functions, the inner wall of the outer shell is equipped with multiple guide rails arranged along the moving direction of the mold block; the side of the mold block is provided with guide grooves that cooperate with the guide rails.

[0013] In the aforementioned crystal processing mold with push-out and pull-back functions, the guide rail is shaped like an "Ω".

[0014] In the aforementioned crystal processing mold with push-out and pull-back functions, the threaded grooves on the two side mold blocks can form a complete closed thread shape.

[0015] Compared with the prior art, this utility model improves the existing crystal processing molding die by setting a push-pull component on the bottom surface of the outer shell. The push-pull component is slidably engaged with the bottom end of all the mold blocks. The push-pull component can not only push all the mold blocks out of the outer shell, but also pull all the mold blocks back into the outer shell. In addition, each mold block is slidably connected to the outer shell, so that the entire crystal processing mold can not only realize the push-out function, reducing the difficulty of demolding and improving the efficiency of demolding, but also has an automatic return function, eliminating the need for manual return operation and making it convenient to use. Furthermore, this utility model also improves stability during the pushing and pulling process by configuring the push-pull component as a chuck and push rod. The chuck increases the contact area between the entire push-pull component and all mold blocks, ensuring greater stability during the pushing and pulling of the mold blocks. A stop piece is provided on the side of the chuck, which engages with the slots of the mold blocks. Even when the pusher pushes all mold blocks out of the housing and away from each other at their maximum stroke, the stop piece remains engaged with the slots on the mold blocks, ensuring the chuck can pull the mold blocks back, guaranteeing stability and a simple overall structure. The invention also features a bottom mold block, an end mold block, and two side mold blocks, each with a half-threaded groove. The bottom mold block provides support and positioning during crystal forming, while the end mold block limits the extrusion position of the molten crystal at the end, ensuring a good crystal forming effect. The water ripple groove and threaded groove further enhance stability. Watermarks and threads are formed directly on the side and one end face of the crystal raw material, eliminating the need for additional processing and cutting, thus improving work efficiency. A groove on the outer shell, aligned with the top center of the side mold block and the bottom of the groove, effectively limits the pressure application position of the external pressurizing equipment, ensuring optimal molding results. Guide rails on the outer shell, working in conjunction with guide grooves on the side of the mold block, limit and guide the movement of the mold block, ensuring stability. The "Ω" shape of the guide rails prevents them from detaching from the mold block, ensuring structural stability. By making the side of the side mold block away from the end face vertical, the side mold block can move laterally along the central axis of the threaded groove during outward movement, preventing damage to the threaded ends of the crystal during demolding and ensuring a successful demolding process. Therefore, this utility model is not only easy to operate, but also has the advantages of high work efficiency, simple structure, good molding effect and high structural stability.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] Example. A crystal processing mold with push-out and pull-back functions, configured as follows: Figures 1 to 8 As shown, it includes an open-shaped outer shell 1 and multiple mold blocks. Each mold block is slidably connected inside the outer shell 1. A push-pull member 2 is provided on the inner bottom surface of the outer shell 1. The push-pull member 2 is slidably engaged with the bottom end of all the mold blocks. The push-pull member 2 pushes all the mold blocks out of the outer shell 1 and pulls them back into the outer shell 1 at the same time.

[0027] The push-pull component 2 includes a push rod 9, the top of which is provided with a chuck 10; each mold block is provided with a slot 3, which slides and engages with the chuck 10; a stop 11 is provided on the side of the chuck 10, and the stop 11 is disposed in the slot 3; when the push rod 9 pushes all the mold blocks out of the outer shell 1 and pulls back the outer shell 1 through the chuck 10, the stop 11 is always located in the slot 3; the mold block includes a bottom mold block 4, an end face mold block 6, and two symmetrically distributed side mold blocks 5, which are arranged in a ring on the outer circumference of the bottom mold block 4; each side mold block 5 has a stop 11 on its side facing the bottom mold block 4. The threaded groove 12 is semi-threaded; each of the side mold blocks 5 has a water ripple groove on the side facing the bottom mold block 4, and the water ripple groove is located between the threaded groove 12 and the end mold block 6; the top surface of the outer shell 1 has a groove 13 at the position corresponding to the middle of the side mold block 5; the top surface of the side mold block 5 has a recessed area 14 flush with the groove 13; the side of the side mold block 5 away from the end mold block 6 is a vertical surface; multiple guide rails 7 are installed on the inner wall of the outer shell 1 along the moving direction of the mold block; the side of the mold block has a guide groove 8 that cooperates with the guide rail 7; the guide rail 7 is Ω-shaped.

[0028] Working principle: In actual use, the entire crystal mold is first placed on the corresponding equipment, and then the push rod 9 on the push-pull component 2 is connected to the external pushing device (the pushing device can be an ejector cylinder). At this time, all the bottom mold blocks 4, side mold blocks 5, and end mold blocks 6 are located inside the outer shell 1. Then, the softened crystal raw material is poured between the bottom mold blocks 4, side mold blocks 5, and end mold blocks 6, and then the external pressure device is used for hot pressing. Because the side mold blocks 5 are provided with water ripple grooves and thread grooves 12, water ripples and threads can be directly formed on the sides and ends of the crystal raw material during the hot pressing process, so no subsequent processing is required. The process involves cutting or carving to achieve an integrated water ripple and thread forming process, improving work efficiency. Simultaneously, due to the threaded groove 12, the bottom mold block 4 can support and position the crystal from below; while the end mold block 6 can limit the extrusion end of the molten crystal at the end to ensure the crystal forming effect. After the forming process is completed, the external pressure device is first separated from the entire crystal mold, and then the push rod 9 is pushed upwards by the external pushing device. During the movement of the push rod 9, the chuck 10 moves together. The chuck 10 is slidably engaged with the side mold block 5 and the end mold block 6 through the slot 3, while the bottom mold block 4 is fixedly installed on the chuck. When the push-pull component 2 moves upward under the action of external force, it will drive the bottom mold block 4 to move upward as well, and at the same time push the side mold block 5 and the end mold block 6 to move upward as well. The side mold block 5 and the end mold block 6 are slidably installed together with the guide rail 7 and the guide groove 8. Therefore, when the side mold block 5 and the end mold block 6 are pushed upward by the chuck 10, they will eventually move along the guide rail 7 under the guidance of the guide rail 7 and the guide groove 8. Since the outer side wall of the side mold block 5 and the end mold block 6 is an inclined surface, and the inner side wall of the outer shell 1 is also an inclined surface, the side mold block 5 and the end mold block 6 move along the guide rail 7 in an inclined upward direction. When the push-pull component 2 pushes the side mold block 5 and the end mold block 6 to the outside of the outer shell 1, the tightening of the top part of the outer shell 1 on the side mold block 5 and the end mold block 6 decreases, thereby increasing the distance between the top parts of the side mold block 5 and the end mold block 6. That is, the side mold block 5 and the end mold block 6 move away from the central axis of the outer shell 1, thereby enabling the side mold block 5 and the end mold block 6 to loosen the crystal after the molding work is completed, so that the operator can easily take out the crystal inside, which facilitates the unloading work and improves the work efficiency (during the entire movement process, the stop component 11 on the chuck 10 remains in a sliding engagement with the slot 3).After the crystal is removed, simply pull the push rod 9 back using the external pushing device. The push rod 9 will then move the chuck 10 into the outer casing 1. During the movement of the chuck 10, it will pull the bottom mold block 4, side mold block 5, and end mold block 6 back into the outer casing 1 through the slot 3, completing the automatic reset process and preparing for the next crystal forming operation. Compared to previous crystal processing molds, this system achieves automatic mold block reset, eliminating the need for manual reset and simplifying operation.
