[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure, followed by cooling and solidification to obtain the molded product. In common traditional molds, the mold core is fixed with locating pins. Disassembly is very time-consuming and labor-intensive when the mold malfunctions, reducing production efficiency and increasing manual labor. Furthermore, the use of locating pins to fix the mold core in traditional molds cannot meet the requirement of simultaneous production of black and white plastic.

[0004] Therefore, it is necessary to propose an MGP mold with a quick-change mold core to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an MGP mold with a quick-change mold core, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A quick-changeable MGP mold includes a mold frame, a mold core inserted into the bottom of the inner cavity of the mold frame, auxiliary positioning components symmetrically installed on both sides of the inner cavity of the mold frame, reinforcing blocks symmetrically and movably connected to the top and bottom of the inner cavity of the auxiliary positioning components, connecting shafts symmetrically and rotatably connected to the top of both sides of the inner cavity of the mold frame, a contact component installed in the center of the outer wall of the connecting shaft, and a positioning component abutting the top of the contact component.

[0008] Preferably, the top of the mold frame has an injection port, both ends of the top and bottom reinforcing blocks are inclined, the outer wall of the mold core has a handle groove, and the center of both sides of the mold core has symmetrical sliding grooves. The auxiliary positioning component is located in the inner cavity of the sliding groove, and the reinforcing block is attached to the inner wall of the sliding groove.

[0009] Preferably, movable blocks are symmetrically installed at both ends of the reinforcing block, and fixed rods are symmetrically installed at both ends of the inner cavity of the auxiliary positioning component. A second spring is wound around the outer wall of the fixed rod. One end of the second spring is connected to the movable block, and the other end of the second spring is installed in the inner cavity of the auxiliary positioning component.

[0010] Preferably, the top of the mold core is symmetrically provided with slots around its perimeter, and the bottom of the positioning component is symmetrically provided with blocks on both sides. The positioning component and the blocks are movably connected in the inner cavity of the mold frame, and the bottom of the blocks penetrates the outer wall of the mold frame and is inserted into the inner cavity of the slots.

[0011] Preferably, a fixing post is installed in the inner cavity of the mold frame, and a limiting block is installed on the top of the fixing post. Both the limiting block and the fixing post are installed in the inner cavity of the mold frame. The limiting block is used to prevent the fixing post from detaching from the inner cavity of the mold frame. A first spring is wound around the outer wall of the fixing post. The top of the first spring is installed at the bottom of the limiting block, and the bottom of the first spring is installed at the top of the positioning assembly. The positioning assembly is sleeved on the outer wall of the fixing post.

[0012] Preferably, the contact component is fan-shaped on the side near the positioning component and inclined on the side away from the positioning component. A rotating handle is installed on the outer wall of the connecting shaft, and the rotating handle is rotatably connected to the outer wall of the mold frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This MGP mold with quick-change mold core consists of a mold frame and a mold core. It is a pull-out type, which allows the mold core to be quickly replaced. If the mold core is damaged during mold making, it can be removed and replaced immediately, so it will not affect the efficiency of mold making. Therefore, it can play a significant role in mold production, effectively improve production efficiency, and save mold maintenance time and costs.

[0015] 2. This MGP mold with quick-change mold core, through the setting of the second spring, after the mold core is slidably connected to the outer wall of the auxiliary positioning component through the slide groove, can drive the reinforcing block to fit into the inner cavity of the slide groove. Therefore, it can play a preliminary positioning treatment for the connection between the mold frame and the injection port. At the same time, the two ends of the reinforcing block are inclined, which makes it convenient for the mold core to be pulled out from the inner cavity of the mold frame.

[0016] 3. This MGP mold with quick-change mold core can rotate the contact component by rotating the rotating handle, which in turn drives the contact component to rotate via the connecting shaft. When the fan-shaped contact component contacts the positioning component, it can lift the component up. At this time, the positioning component can drive the locking block to rise, thus disengaging the locking block from the inner cavity of the slot. This makes it easy to pull the mold core out of the mold frame's inner cavity. After continuing to rotate the contact component, its tilt will be positioned at the bottom of the positioning component. At this time, the first spring can press down the positioning component, allowing the locking block to be inserted into the inner cavity of the slot. Therefore, the injection port can be fixed after installation. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-4As shown, an MGP mold with a quick-change mold core includes a mold frame 1. A mold core 3 is inserted into the bottom of the inner cavity of the mold frame 1. Auxiliary positioning components 6 are symmetrically installed on both sides of the inner cavity of the mold frame 1. Reinforcing blocks 16 are symmetrically and movably connected to the top and bottom of the inner cavity of the auxiliary positioning components 6. Connecting shafts 9 are symmetrically and rotatably connected to the top of both sides of the inner cavity of the mold frame 1. A contact component 10 is installed in the center of the outer wall of the connecting shaft 9. A positioning component 11 is attached to the top of the contact component 10. An injection port 2 is opened at the top of the mold frame 1. Both ends of the bottom reinforcing block 16 are inclined. The outer wall of the mold core 3 is provided with a handle groove 4. The center of both sides of the mold core 3 is symmetrically provided with sliding grooves 5. The auxiliary positioning component 6 is located in the inner cavity of the sliding groove 5. The reinforcing block 16 fits into the inner wall of the sliding groove 5. Movable blocks 17 are symmetrically installed at both ends of the reinforcing block 16. Fixed rods 18 are symmetrically installed at both ends of the inner cavity of the auxiliary positioning component 6. The outer wall of the fixed rod 18 is wound with a second spring 19. One end of the second spring 19 is connected to the movable block 17, and the other end of the second spring 19 is installed... The mold core 3 is symmetrically provided with slots 7 around its top perimeter, and the positioning component 11 has symmetrically provided locking blocks 12 on both sides of its bottom. Both the positioning component 11 and the locking blocks 12 are movably connected to the inner cavity of the mold frame 1. The bottom of the locking blocks 12 penetrates the outer wall of the mold frame 1 and is inserted into the inner cavity of the slots 7. A fixing post 13 is installed in the inner cavity of the mold frame 1, and a limiting block 14 is installed on the top of the fixing post 13. Both the limiting block 14 and the fixing post 13 are installed in the inner cavity of the mold frame 1. The limiting block 14 is used for... To prevent the fixed column 13 from detaching from the inner cavity of the mold frame 1, a first spring 15 is wound around the outer wall of the fixed column 13. The top of the first spring 15 is installed at the bottom of the limiting block 14, and the bottom of the first spring 15 is installed at the top of the positioning component 11. The positioning component 11 is sleeved on the outer wall of the fixed column 13. The side of the contact component 10 near the positioning component 11 is fan-shaped, and the side of the contact component 10 away from the positioning component 11 is inclined. A rotating handle 8 is installed on the outer wall of the connecting shaft 9. The rotating handle 8 is rotatably connected to the outer wall of the mold frame 1.

[0024] The mold consists of a mold frame 1 and a mold core 3, which is a pull-out design, allowing for quick replacement of the mold core 3. If the mold core 3 is damaged during molding, it can be removed and replaced immediately, thus not affecting molding efficiency. This significantly improves production efficiency and saves on mold maintenance time and costs. A second spring 19, after the mold core 3 slides along the groove 5 to the outer wall of the auxiliary positioning component 6, drives the reinforcing block 16 to fit into the inner cavity of the groove 5. This provides initial positioning for the connection between the mold frame 1 and the injection port 2. Furthermore, the two ends of the reinforcing block 16 are inclined, facilitating... Subsequently, the mold core 3 is pulled out from the inner cavity of the mold frame 1. By rotating the rotating handle 8, the contact component 10 can be rotated through the connecting shaft 9. When the fan-shaped contact component 10 contacts the positioning component 11, it can be lifted up. At this time, the positioning component 11 can drive the locking block 12 to rise, and the locking block 12 can be disengaged from the inner cavity of the slot 7. This makes it easy to pull the mold core 3 out from the inner cavity of the mold frame 1. After continuing to rotate the contact component 10, its tilt will be located at the bottom of the positioning component 11. At this time, the first spring 15 can press down the positioning component 11, so that the locking block 12 can be inserted into the inner cavity of the slot 7. Therefore, the injection port 2 after installation can be fixed.

[0025] It should be noted that this utility model is an MGP mold with quick core replacement. When the core 3 needs to be replaced, the auxiliary positioning component 6 is rotated so that the connecting shaft 9 can drive the contact component 10 to rotate. The contact component 10 lifts the positioning component 11 through its fan-shaped position, thereby disengaging the locking block 12 from the inner cavity of the slot 7. At this time, the core 3 can be pulled out from the inner cavity of the mold frame 1.

[0026] When a new mold core 3 needs to be installed, continue to lift the positioning component 11 and insert the mold core 3 into the inner cavity of the mold frame 1. The mold core 3 is fitted onto the outside of the auxiliary positioning component 6 through the slide groove 5. At the same time, the second spring 19 pushes the reinforcing block 16 against the inner wall of the slide groove 5 through the movable block 17 until they fit together. After the mold core 3 is fully inserted into the inner cavity of the mold frame 1, rotate the handle 8 in the opposite direction so that the inclined position of the contact component 10 can be located at the bottom of the positioning component 11. At this time, the first spring 15 can press down the positioning component 11 so that the locking block 12 can be inserted into the inner cavity of the locking slot 7, thus completing the connection between the mold frame 1 and the mold core 3.
