Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically a novel simple sliding mold opening mechanism. Background Technology

[0002] Mold slides are mechanisms in molds that enable lateral parting and core pulling. For example, in injection molds, some products have side holes or side recesses. Slides can pull out the side cores when the mold opens and reset them when the mold closes, ensuring that the product is formed smoothly. Mobile phone casing molds often use slides to form the side button hole structure.

[0003] Existing injection-molded products cannot meet the requirements for secondary injection molding when using slide mold opening mechanisms, and the mold opening efficiency is low, making it difficult to accurately monitor the mold opening process. Therefore, this does not meet the current needs. To address this, we propose a new and simplified slide mold opening mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a new and simple slide mold opening mechanism to solve the problems mentioned in the background art, such as the inability of existing injection molded products to meet the requirements of secondary injection molding when opening the mold through the slide, low mold opening efficiency, and inconvenience for accurate monitoring of mold opening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel simple sliding mold opening mechanism, comprising a central connecting seat, a positioning rod installed in the middle of the upper surface of the central connecting seat, a central cone block fixedly installed at the upper end of the positioning rod, sliding blocks installed on both sides of the central cone block, an elastic plate installed between the central cone block and the two sliding blocks, a shaping contact surface provided at the end of each of the two sliding blocks away from the central cone block, an inclined groove provided on the inner side of the sliding block, a sliding rod installed on the inner side of the inclined groove, and springs provided at both ends of the two sliding rods;

[0006] One of the positioning blocks has an inclined top unit installed on its upper end. The inclined top unit includes an inclined insert. Two connecting rods are fixedly installed on the upper end of the inclined insert. Two caps are installed on one side of the inclined insert. An installation sleeve is installed between the bottom end of the inclined insert and the cap. A pressure sensor is fixedly installed on the inner side of the installation sleeve. A sliding cover is installed on one end of the pressure sensor.

[0007] Preferably, both ends of the central connecting seat are equipped with bottom molds, and the upper surface of the bottom mold is provided with an injection groove.

[0008] Preferably, the two sliding blocks and the bottom mold are symmetrically installed relative to the central cone block. The central cone block is fixedly connected to both elastic plates. The central cone block and the two sliding blocks are connected through elastic plates. The sliding blocks are fixedly connected.

[0009] Preferably, the upper end face of the central connecting seat is provided with a sliding groove, the bottom ends of the central cone block and the two sliding blocks are inserted into the inner side of the sliding groove, the central connecting seat is slidably connected to the central cone block and the two sliding blocks, each of the sliding blocks is connected to both ends of the slide rod by a spring, and the slide rod slides linearly back and forth along the axis of the inclined groove.

[0010] Preferably, the bottom end of the central connecting seat is provided with a shifting turntable, the central connecting seat is fixedly connected to the shifting turntable, and an upper mold seat is provided above both bottom molds.

[0011] Preferably, the inclined insert is fixedly connected to two adjacent caps, the caps are in contact with the inner wall of the inclined groove away from the slide bar, and the slide cap is slidably connected to the caps.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the upper mold base is moved down and fits with one of the bottom molds away from the inclined top unit. At this time, the injection cavity between the upper mold base and the bottom mold is subjected to the first injection molding. Then, the upper mold base is demolded from the product and the two bottom molds are moved by the shift turntable through the central connecting seat and two sliding blocks. This allows the upper mold base to be vertically adjusted again and to close, inject and open the mold with one of the bottom molds, realizing the secondary injection molding operation of the product.

[0014] 2. This utility model moves the inclined top unit downward, allowing the inclined insert to be inserted into the inner side of one of the inclined grooves. The sliding block is driven by the slide rod and spring to slide on the upper surface of the central connecting seat. As a result, the sliding block separates from the bottom mold, and the shaping contact surface can automatically demold from the product, which facilitates the mold opening operation. One end of the pressure sensor contacts the inner wall of the inclined groove through the sliding cover. When the bottom end of the inclined insert is inserted into the inner side of the inclined groove, the sliding cover is pressed and slides in the middle of the cover, which pressurizes the pressure sensor. The pressure sensor facilitates accurate monitoring of the mold opening of the sliding block. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 This utility model provides an embodiment of a novel simple sliding mold opening mechanism, including a central connecting seat 1. A shifting turntable is provided at the bottom of the central connecting seat 1, and the central connecting seat 1 is fixedly connected to the shifting turntable. A positioning rod 11 is installed in the middle of the upper surface of the central connecting seat 1. A central cone block 3 is fixedly installed at the upper end of the positioning rod 11. Sliding blocks 2 are installed on both sides of the central cone block 3. An elastic plate 10 is installed between the central cone block 3 and the two sliding blocks 2. A shaping contact surface 12 is provided at the end of each sliding block 2 away from the central cone block 3. The central cone block 3 is fixedly connected to the two elastic plates 10, and the central cone block 3 and the two sliding blocks 2 are connected through the elastic plates 10. A sliding groove is provided on the upper surface of the central connecting seat 1. The bottom ends of the central cone block 3 and the two sliding blocks 2 are inserted into the inner side of the sliding groove. The central connecting seat 1 is slidably connected to the central cone block 3 and the two sliding blocks 2. The two sliding blocks 2 facilitate sliding mold opening of the product during secondary injection molding.

[0022] Please see Figures 1 to 3 Both ends of the central connecting seat 1 are equipped with bottom molds 4. The upper surface of the bottom mold 4 is provided with an injection groove 6. The upper mold base is provided above the two bottom molds 4. The two sliding blocks 2 and the bottom molds 4 are symmetrically installed relative to the central cone block 3. The sliding blocks 2 and 4 are fixedly connected. The inner side of the sliding block 2 is provided with a sloping groove 7. The inner side of the sloping groove 7 is equipped with a sliding rod 8. Both ends of the two sliding rods 8 are provided with springs 9. Each sliding block 2 is connected to both ends of the sliding rod 8 through the springs 9. The sliding rod 8 slides linearly back and forth along the axis of the sloping groove 7, so that when the inclined top unit 5 is inserted into the inner side of one of the sloping grooves 7, the sliding block 2 is driven to slide on the upper surface of the central connecting seat 1 through the sliding rod 8 and the springs 9.

[0023] Please see Figure 3 and Figure 4One of the slide blocks 2 has a slanted top unit 5 installed on its upper end. The slanted top unit 5 includes a slanted insert 501. Two connecting rods 502 are fixedly installed on the upper end of the slanted insert 501. Two caps 503 are installed on one side of the slanted insert 501. An installation sleeve 505 is installed between the bottom end of the slanted insert 501 and the caps 503. A pressure sensor 506 is fixedly installed on the inner side of the installation sleeve 505. A sliding cover 504 is installed on one end of the pressure sensor 506. The slanted insert 501 is fixedly connected to the two adjacent caps 503. The caps 503 are in contact with the inner wall of the slanted groove 7 away from the slide rod 8. The sliding cover 504 is slidably connected to the caps 503. The sliding cover 504 is pressed and slides in the middle of the caps 503 and applies pressure to the pressure sensor 506. Thus, the pressure sensor 506 facilitates accurate monitoring of the mold opening of the slide block 2.

[0024] In summary, when performing secondary injection molding on the product, the center connecting seat 1 is fixed on the shifting turntable, the power is turned on, the upper mold seat is moved down and fits against one of the bottom molds 4 away from the inclined ejector unit 5. At this time, the injection cavity between the upper mold seat and the bottom mold 4 is subjected to the first injection molding. Then, the upper mold seat is demolded from the product, and the shifting turntable is used to drive the two bottom molds 4 to shift through the center connecting seat 1 and the two sliding blocks 2. This allows the upper mold seat to be vertically adjusted again and to close, inject, and open the mold with one of the bottom molds 4, thus realizing the secondary injection molding operation of the product.

[0025] At this time, the inclined top unit 5 is moved down, so that the inclined insert 501 is inserted into the inner side of one of the inclined grooves 7, and the sliding block 2 is driven to slide on the upper end face of the central connecting seat 1 through the slide rod 8 and the spring 9. Thus, the sliding block 2 separates from the bottom mold 4, and the shaping contact surface 12 can automatically demold from the product, which facilitates the sliding mold opening operation. One end of the pressure sensor 506 contacts the inner wall of the inclined groove 7 through the sliding cover 504. Thus, when the bottom end of the inclined insert 501 is inserted into the inner side of the inclined groove 7, the sliding cover 504 is pressed and slides in the middle of the cover 503 and pressurizes the pressure sensor 506. Thus, the pressure sensor 506 facilitates accurate monitoring of the mold opening of the sliding block 2.
