Technical Field

[0001] This application relates to the field of mold structure technology, and in particular to a mold frame for a rear template assembly. Background Technology

[0002] Currently, the rear mold plate typically refers to the part in mold design that corresponds to the front mold, mainly used for the moving mold or moving mold core during the molding process. In injection molds, the part with the injection port is usually called the front mold, while the part without the injection port that cooperates with the front mold to complete the molding action is called the rear mold. The mold base is the supporting structure of the mold, and also the skeleton of the entire mold. It is a semi-finished product of the mold, composed of various steel plates and mating parts.

[0003] However, the existing mold frame of a rear template assembly has the following drawbacks: for example, the mold frame is usually fixed to the rear template with bolts, which makes it time-consuming and labor-intensive to replace the rear template, affecting the replacement efficiency between the mold frame and the rear template and making it inconvenient to use the mold frame. Summary of the Invention

[0004] The purpose of this application is to solve the problem that the bolted connection between the mold frame and the rear template makes the replacement of the rear template time-consuming and affects the efficiency of the replacement between the mold frame and the rear template.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: The main body has a receiving groove on its upper surface and a placement groove on its inner surface. An installation assembly is installed inside the main body. The installation assembly includes a fixing block, the surface of which is fixedly connected to the side surface of the main body. A spring is fixedly connected to the side surface of the fixing block, and a locking block is fixedly connected to one end of the spring. A rotating groove is formed on the side surface of the main body, and a rotating block is movably connected inside the rotating groove. A rotating seat is fixedly connected to the side surface of the rotating block, and a locking groove is formed on the outer surface of the rotating seat. A rear template is movably connected inside the receiving groove, and a connecting rod is fixedly connected to the side surface of the rear template. The connecting rod is located inside the placement groove.

[0006] As a preferred embodiment, a slider is provided on the side surface of the main body, and a sliding groove is movably connected inside the slider, with the side surface of the sliding groove being fixedly connected to the side surface of the locking block.

[0007] As a preferred embodiment, four guide posts are fixedly connected to the upper surface of the main body, and two square irons are fixedly connected to the lower surface of the main body.

[0008] As a preferred embodiment, a base plate is fixedly connected to the lower surface of the square iron, and a through hole is provided on the lower surface of the base plate, the through hole being located in the center of the base plate.

[0009] As a preferred embodiment, the upper surface of the base plate is provided with a top plate, the upper surface of the top plate is fixedly connected with a pin panel, the upper surface of the pin panel is fixedly connected with a pin, the lower surface of the main body is provided with a connecting hole, the upper end of the connecting hole extends through the interior of the main body to the interior of the rear template, and the upper end of the pin is located inside the connecting hole.

[0010] As a preferred embodiment, the upper surface of the main body is provided with a reset hole, the upper surface of the ejector plate is fixedly connected with a reset rod, the upper end of the reset rod is located inside the reset hole, and the upper surface of the ejector plate is fixedly connected with a reset spring, the upper end of the reset spring being fixedly connected to the lower surface of the main body.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] By using a receiving slot, a placement slot, an installation component, a rear template, and a connecting rod, during replacement, a control block is moved to disengage from the rotating seat. Then, the rotating seat is rotated so that the slot is vertically upward and overlaps with the placement slot. At this point, the rear template can be removed via the connecting rod. The replacement rear template is then placed into the receiving slot, and the connecting rod enters the placement slot. The rotating seat is rotated so that the slot is horizontal and perpendicular to the placement slot. At this point, the locking block moves towards the rotating seat under the action of the spring and locks into the slot, preventing the rotating seat from rotating and thus preventing the connecting rod from moving. This completes the template replacement. Compared to existing mold frames that typically use bolts to fix the rear template, which requires a lot of time and effort to replace the rear template and affects the efficiency of the mold frame replacement, this rear template component mold frame can quickly and easily complete the installation and replacement of the rear template, saving time and effort, improving the efficiency of the mold frame replacement, and facilitating the use of the mold frame.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] like Figure 1-9 The mold frame of a rear template assembly shown includes a main body 1. A receiving groove 101 is formed on the upper surface of the main body 1, and a placement groove 102 is formed on the inner surface of the receiving groove 101. An installation assembly 2 is installed inside the main body 1. The installation assembly 2 includes a fixing block 201, the surface of which is fixedly connected to the side surface of the main body 1. A spring 202 is fixedly connected to the side surface of the fixing block 201, and a locking block 203 is fixedly connected to one end of the spring 202. A rotating groove 204 is formed on the side surface of the main body 1. The rotating groove 204 has a convex cross-section, which can restrict the rotating block 205. The rotating groove 204 is integrally formed. The rotating block 205 is semi-circular, allowing it to rotate 90 degrees within the rotating groove 204. The rotating block 205 is movably connected inside the rotating groove 204. The rotating block 205 has a convex cross-section, allowing it to be engaged within the rotating groove 204 and preventing it from disengaging. The rotating block 205 is also quarter-arc shaped, enabling it to drive the rotating seat 206 to rotate 90 degrees. The rotating seat 206 is fixedly connected to the side surface of the rotating block 205, allowing it to rotate 90 degrees. This allows the slot 207 to be in both a vertically upward and horizontal position. When the slot 207 is vertically upward, the connecting... The connecting rod 4 can be picked up and put down. When the slot 207 is in a horizontal state, the connecting rod 4 cannot move, thus preventing the rear template 3 from moving. This facilitates the use of the mold frame to support the rear template 3. The outer surface of the rotating seat 206 has a slot 207. The rear template 3 is movably connected inside the receiving slot 101. The connecting rod 4 is fixedly connected to the side surface of the rear template 3. The connecting rod 4 is located inside the placement slot 102. The side surface of the main body 1 has a slider 5. The inside of the slider 5 is movably connected to a sliding groove 6. The side surface of the sliding groove 6 is fixedly connected to the side surface of the locking block 203. During replacement, the locking block 203 is controlled to move, so that the locking block 203... 03. Disconnect from the rotating seat 206, then rotate the rotating seat 206 so that the slot 207 is vertically upward and overlaps with the placement slot 102. At this time, the rear template 3 can be removed by the connecting rod 4. Then, place the replacement rear template 3 into the receiving slot 101. The connecting rod 4 enters the placement slot 102. Rotate the rotating seat 206 so that the slot 207 is horizontal and perpendicular to the placement slot 102. At this time, the locking block 203 moves towards the rotating seat 206 under the action of the spring 202 and locks into the slot 207, restricting the rotating seat 206 from rotating. This prevents the connecting rod 4 from moving. At this time, the replacement of the template 3 is completed.

[0028] Four guide pillars 7 are fixedly connected to the upper surface of the main body 1. The guide pillars 7 can guide the mold frame to drive the rear template 3 to rise. Two square iron blocks 8 are fixedly connected to the lower surface of the main body 1. The square iron blocks 8 can create a certain distance between the main body 1 and the base plate 9 to facilitate the up and down movement of the ejector pins 13. The base plate 9 is fixedly connected to the lower surface of the square iron blocks 8. The lower surface of the base plate 9 has a through hole 10. The through hole 10 is located in the center of the base plate 9. When the mold frame descends, the ejector pins can pass through the through hole 10, thereby pushing the top plate 11 upward, thereby driving the ejector pins 13 to rise for demolding. The top plate 11 is provided on the upper surface of the base plate 9. The top plate 11 can withstand the pushing of the ejector pins below. The ejector pin panel 12 is fixedly connected to the upper surface of the top plate 11. The ejector pin panel 12 can drive the ejector pins 13 to rise. The ejector pins are fixedly connected to the upper surface of the ejector pin panel 12. 13. A connecting hole 14 is provided on the lower surface of the main body 1. The upper end of the connecting hole 14 extends through the interior of the main body 1 to the interior of the rear template 3. The upper end of the ejector pin 13 is located inside the connecting hole 14. The ejector pin 13 can move up and down through the connecting hole 14, thereby pushing the workpiece upward to demold. A reset hole 15 is provided on the upper surface of the main body 1. The reset hole 15 facilitates the up and down movement of the reset rod 16. The reset rod 16 is fixedly connected to the upper surface of the ejector pin panel 12. The upper end of the reset rod 16 is located inside the reset hole 15. A reset spring 17 is fixedly connected to the upper surface of the ejector pin panel 12. The upper end of the reset spring 17 is fixedly connected to the lower surface of the main body 1. When the ejector pin 13 rises, the reset spring 17 is passively compressed. When the ejector pin 13 rises and completes demolding, the reset spring 17 rebounds, pushing the ejector pin panel 12 down and driving the ejector pin 13 down to its original position for the next operation.

[0029] Working principle: During replacement, control block 203 moves to disengage from rotating seat 206. Then, rotate rotating seat 206 so that slot 207 is vertically upward and overlaps with placement slot 102. At this time, the rear template 3 can be removed via connecting rod 4. The replacement rear template 3 is then placed into receiving slot 101, and connecting rod 4 enters placement slot 102. Rotate rotating seat 206 so that slot 207 is horizontal and perpendicular to placement slot 102. At this time, block 203 moves towards rotating seat 206 under the action of spring 202 and engages in slot 207, preventing rotating seat 206 from rotating and thus preventing connecting rod 4 from moving. The replacement of template 3 is then completed.
