Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to a projector shell molding mold. Background Technology
[0002] In the field of electronic product manufacturing, projectors are important image output devices, and the molding quality of their casings has a critical impact on the product's performance, appearance, and assembly precision. As the core equipment for projector casing production, molding molds directly determine production efficiency and product quality. With the continuous growth of market demand for projectors and the accelerated pace of product upgrades, higher requirements are being placed on the efficiency, stability, and maintainability of projector casing molding molds.
[0003] Currently, traditional projector housing molding molds typically use fixed installation for the guide pillars. When a guide pillar is damaged and needs replacement, independent disassembly and replacement are difficult, often requiring significant adjustments to the entire mold structure. This is not only complex but also necessitates precise repositioning during replacement, consuming considerable time and manpower. In scenarios involving the disassembly and assembly of multiple guide pillars, locking and unlocking each pillar requires individual operation, resulting in a cumbersome and inefficient process. The drawbacks of this approach are particularly pronounced in scenarios involving frequent guide pillar replacements and batch adjustments, failing to meet the demands of efficient production in modern electronic product manufacturing. Therefore, a projector housing molding mold is needed to address the problems existing in current technologies. Utility Model Content
[0004] The purpose of this utility model is to provide a projector housing molding mold to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a projector housing molding die, comprising:
[0006] A mold base plate and a support base, wherein the support base is fixed to the upper end of the mold base plate and is used to support the forming mold;
[0007] The guide post is slidably connected in the positioning slot of the support base, and the guide post is used to guide the opening and closing of the mold;
[0008] A locking mechanism is embedded and fixed inside the support base, and the locking mechanism is used to limit the position of the guide post;
[0009] A synchronous switching mechanism is fixed on two sets of locking mechanisms and is used to switch the locking state of the locking mechanisms.
[0010] Preferably, the locking mechanism includes guide slide boxes, two of which are respectively embedded and fixed in two support seats, and the guide slide boxes are slidably connected to limit slide pins.
[0011] Preferably, a translation slider is fixed to one end of the limiting slide post that extends into the guide slide box, and a return spring is sleeved on the part of the limiting slide post that extends into the guide slide box. One end of the return spring is fixed to the inner end wall of the guide slide box, and the other end of the return spring is fixed to the end face of the translation slider.
[0012] Preferably, the synchronous switching mechanism includes a second extrusion wheel set, a first extrusion wheel set is provided on one side of the translation slider, the second extrusion wheel set is disposed opposite to one side of the first extrusion wheel set, and a lifting carriage is provided on one side of the second extrusion wheel set.
[0013] Preferably, both the first extrusion wheel set and the second extrusion wheel set include roller brackets. The roller bracket in the first extrusion wheel set is fixed to the end face of the translation slider, and the roller bracket in the second extrusion wheel set is fixed to the end face of the lifting slide. Extrusion rollers are rotatably connected to the surface of the roller bracket.
[0014] Preferably, both the guide slide box and the support base have lifting grooves on one side surface, and the lifting slide is slidably connected in the lifting grooves.
[0015] Preferably, a limiting hole is formed on the side surface of the guide post, and the limiting slide post is properly matched with the limiting hole of the guide post.
[0016] Preferably, the two lifting carriages are slidably connected in two guide boxes.
[0017] This utility model provides a projector housing molding die, which has the following advantages compared with the prior art:
[0018] With the locking mechanism in place, the limiting slide pin is embedded in the limiting hole of the guide pin to lock the position of the guide pin in the positioning slot of the support. Similarly, after the lifting slide is raised and adjusted, the limiting slide pin is automatically reset under the action of the return spring to release the movement restriction of the guide pin in the positioning slot of the support. This detachable guide pin design provides the conditions for independent replacement of the guide pin on the mold, and the newly replaced guide pin can save the positioning adjustment step by accurately embedding it in the correct position.
[0019] By adjusting the synchronous switching mechanism, the two sets of locking mechanisms can be unlocked synchronously by raising the synchronous switching mechanism during the locking and unlocking process of the guide pillars, and the two sets of locking mechanisms can be locked synchronously by lowering the synchronous switching mechanism. This simplifies the tedious process of disassembling and assembling multiple guide pillars and saves time. The efficiency improvement is more obvious, especially in scenarios such as frequent replacement of guide pillars and batch adjustment of working conditions. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0029] Please see Figure 1-7 This utility model provides a projector housing molding die, comprising:
[0030] The mold base plate 1 and the support base 2 are fixed to the upper end of the mold base plate 1 and are used to support the forming mold.
[0031] Guide post 3 is slidably connected in the positioning slot of support base 2, and guide post 3 is used for guiding the opening and closing of mold;
[0032] Locking mechanism 4 is embedded and fixed inside the support base 2. Locking mechanism 4 is used to limit the guide post 3. Locking mechanism 4 includes guide slide box 6. Two guide slide boxes 6 are embedded and fixed in the two support bases 2 respectively. The guide slide box 6 is slidably connected to the inside of the guide slide box 6. One end of the limit slide post 7 that extends into the guide slide box 6 is fixed with a translation slider 8. The part of the limit slide post 7 that extends into the guide slide box 6 is fitted with a return spring 9. One end of the return spring 9 is fixed on the inner end wall of the guide slide box 6, and the other end of the return spring 9 is fixed on the end face of the translation slider 8.
[0033] When the mold is in operation, the guide post 3 is positioned in the positioning slot of the support seat 2, providing precise guidance for the opening and closing of the mold. If the guide post 3 is damaged, the detachable design provides the conditions for independent replacement of the guide post 3 on the mold. Moreover, the newly replaced guide post 3 can save the positioning adjustment steps by accurately embedding it in the correct position.
[0034] The synchronous switching mechanism 5 is fixed on two sets of locking mechanisms 4. The synchronous switching mechanism 5 is used to switch the locking state of the locking mechanism 4. The synchronous switching mechanism 5 includes a second extrusion wheel group 11. A first extrusion wheel group 10 is provided on one side of the translation slider 8. The second extrusion wheel group 11 is provided on the opposite side of the first extrusion wheel group 10. A lifting slide 12 is provided on one side of the second extrusion wheel group 11. Both the first extrusion wheel group 10 and the second extrusion wheel group 11 include roller brackets 14. The roller brackets 14 in the first extrusion wheel group 10 are fixed on the end face of the translation slider 8. The roller brackets 14 in the second extrusion wheel group 11 are fixed on the end face of the lifting slide 12. Extrusion rollers 15 are rotatably connected to the surface of the roller brackets 14. Lifting grooves 13 are opened on one side surface of the guide slide box 6 and the support seat 2. The lifting slide 12 is slidably connected in the lifting groove 13. The two lifting slides 12 are slidably connected in the two guide slide boxes 6.
[0035] During the locking and unlocking process of the guide post 3, adjusting the synchronous switching mechanism 5 to rise can achieve the synchronous unlocking of the two sets of locking mechanisms 4, and adjusting the synchronous switching mechanism 5 to fall can achieve the synchronous locking of the two sets of locking mechanisms 4. This simplifies the tedious process of disassembling and assembling multiple guide posts 3, saving time spent on disassembly and assembly. The efficiency improvement is even more obvious in scenarios such as frequent guide post replacement and batch adjustment of working conditions.
[0036] Further as Figure 1 As shown, it is worth noting that a limiting hole 16 is provided on the side surface of the guide post 3, and the limiting slide post 7 is properly matched with the limiting hole 16 of the guide post 3.
[0037] The limiting slide 7 is embedded in the limiting hole 16 of the guide post 3 to lock the position of the guide post 3 in the positioning slot of the support 2. Similarly, after the lifting slide 12 is raised and adjusted, the limiting slide 7 is automatically reset under the action of the reset spring 9 to release the movement restriction of the guide post 3 in the positioning slot of the support 2.
[0038] In the electronics manufacturing industry, projectors, as important image output devices, have a critical impact on the performance, appearance, and assembly precision of their casings due to the quality of their molding. The molding die, as the core equipment in projector casing production, directly determines production efficiency and product quality. During long-term use, some components of the die, such as guide pillars, are prone to wear and damage, requiring timely repair and replacement. Therefore, the molding of projector casings necessitates a mold with efficient maintenance capabilities to ensure production progress. Its working principle is as follows:
[0039] When the mold is in operation, the guide post 3 is positioned in the positioning slot of the support base 2, providing precise guidance for the opening and closing of the mold, preventing the mold from shifting during the opening and closing process, and ensuring the dimensional accuracy of the projector shell molding.
[0040] After the guide post 3 is adjusted and the limiting hole 16 is accurately inserted into the positioning slot of the support 2, the lifting slide 12 is pushed down to slide in the lifting slide groove 13. The lifting slide 12 drives the second extrusion roller group 11 to move. The extrusion roller 15 in the second extrusion roller group 11 and the extrusion roller 15 in the first extrusion roller group 10 roll against each other to extrude the translation slider 8 to slide outward in the guide slide box 6, overcoming the elastic force of the return spring 9, so that the end of the limiting slide 7 extending out of the guide slide box 6 slides outward. Finally, the limiting slide 7 is embedded in the limiting hole 16 of the guide post 3 to lock the position of the guide post 3 in the positioning slot of the support 2. Similarly, after the lifting slide 12 is raised and adjusted, the limiting slide 7 is automatically reset under the action of the return spring 9 to release the movement restriction of the guide post 3 in the positioning slot of the support 2. This detachable design of the guide post 3 provides the conditions for independent replacement of the guide post 3 on the mold, and the newly replaced guide post 3 can save the positioning adjustment step by accurately embedding it in the correct position.
[0041] During the locking and unlocking process of the guide post 3, adjusting the synchronous switching mechanism 5 to rise can achieve the synchronous unlocking of the two sets of locking mechanisms 4, and adjusting the synchronous switching mechanism 5 to fall can achieve the synchronous locking of the two sets of locking mechanisms 4. This simplifies the tedious process of disassembling and assembling multiple guide posts 3, saving time spent on disassembly and assembly. The efficiency improvement is even more obvious in scenarios such as frequent guide post replacement and batch adjustment of working conditions.
