Description

Technical Field

[0001] This utility model relates to mold devices, and more particularly to a mold device with a cylinder-driven side-push hook needle mechanism. Background Technology

[0002] An existing mold assembly includes a mold unit and a feeding mechanism. The mold unit includes three templates arranged sequentially along a first direction and at least one mold cavity. The feeding mechanism's feed channel needs cleaning, therefore a hook pin is required. Publication number CN203901621U discloses an automatic removal mechanism for the main runner of a three-plate injection mold, including a pusher plate, a fixed mold plate, a fixed mold fixing plate, a hook pin, and a sprue sleeve. The fixed mold fixing plate is fixedly mounted on an injection molding machine. The pusher plate and the fixed templates are sequentially and movably connected to the fixed mold fixing plate. The fixed mold plate has a main runner cavity. It also includes an ejection mechanism disposed between the hook pin and the sprue sleeve cavity. The ejection mechanism includes an elastic element cavity on the fixed mold fixing plate and a buffer cavity on the pusher plate. The elastic element cavity and the buffer cavity are connected. The ejection mechanism also includes an elastic element and a guide rod. The guide rod includes a connecting end and an ejection end fixedly connected together. The connecting end is movably disposed on the fixed mold fixing plate, and the elastic element is sleeved on the connecting end. The ejection method, which uses hooks to release material, suffers from drawbacks such as inconsistent elasticity and poor control precision. Utility Model Content

[0007] The cylinder-side push hook needle mechanism includes a cylinder mechanism installed on the first template, a push block fixed to the piston rod of the cylinder mechanism, and a hook needle. The push block is provided with an inclined guide surface. The hook needle passes through the second template along the first direction and the first end of the hook needle extends into the connection point. The second end cooperates with the inclined guide surface to drive the hook needle to move along the first direction through the piston rod.

[0008] The first feed channel is set perpendicular to the first direction, and the second feed channel is set along the first direction.

[0009] The push block has a mating surface with a clearance groove along a first direction. The mating surface includes the aforementioned inclined guide surface. A mating head is fixed at the second end of the hook needle. The first end of the hook needle passes through the clearance groove. The mating head is hooked onto the push block and mates with the mating surface.

[0032] Product 5, Part 1 51, Part 2 52. Detailed Implementation

[0033] Please refer to Figures 1 to 11 A mold device with a cylinder-side push hook needle mechanism includes a mold unit 1, a first feeding mechanism 2, a cylinder-side push hook needle mechanism, and a second feeding mechanism.

[0034] The mold unit 1 includes a first template 11, a second template 12 and a third template 13 arranged sequentially along a first direction, so that the first template 11, the second template 12 and the third template 13 can be joined and separated along the first direction. At least one mold cavity 14 is provided between the second template 12 and the third template 13 of the mold unit 1. To improve production efficiency, multiple mold cavities 14 can be provided.

[0035] The first feeding mechanism 2 includes a first nozzle 21, a first feeding channel 22 and a second feeding channel 23 connected to the first nozzle 21; the second template 22 is provided with a nozzle groove, and the first nozzle 21 extends into the nozzle groove along a first direction; the first feeding channel 22 is formed between the second template 12 and the third template 13. If the third template 13 is recessed with a channel groove, the first feeding channel 22 is formed when the second template and the third template are closed. The first feeding channel 22 is set perpendicular to the first direction, and one end of the first feeding channel 22 extends into the nozzle groove to connect to the first nozzle 21; the second feeding channel 23 extends from the third template 13 to the mold cavity 14. The second feeding channel 23 is set along the first direction, and the first feeding channel 22 and the second feeding channel 23 are connected and have a connection point 231.

[0036] The cylinder-side push hook needle mechanism 3 includes a cylinder mechanism 31 installed on the first template 11, a push block 32 fixed to the piston rod 311 of the cylinder mechanism 31, and a hook needle 33. The piston 311 of the cylinder mechanism 31 can push the push block 32 to move along a vertical first direction. The push block 32 is provided with an inclined guide surface 321. The hook needle 33 passes through the second template 12 along the first direction, and the first end of the hook needle 33 extends into the connection point 231, and the second end cooperates with the inclined guide surface 321 to drive the hook needle 33 to move along the first direction to hook material through the piston rod 311 and the push block 32. It can be driven by the cylinder mechanism to achieve accurate hooking. The cylinder is easy and flexible to install.

[0037] The push block 32 has a mating surface with a clearance groove 322 along the first direction. The mating surface includes the aforementioned inclined guide surface 321. A mating head 331 is fixed to the second end of the hook needle 33. The first end of the hook needle 33 passes through the clearance groove 322. The clearance groove 332 and the hook needle 33 slide and adapt to each other along the vertical first direction. The mating head 331 is attached to the push block 33 and engages with the mating surface. Then, the piston rod 311 and the push block 32 move along the vertical first direction, and the clearance groove 322 slides relative to the hook needle 33. The inclined guide surface 321 acts on the mating head 331 to drive the hook needle 33 to move along the first direction. The cylinder-side push hook needle mechanism 3 has a compact structure and accurate guidance.

[0038] The mating surface of the push block 32 also includes a plane perpendicular to the first direction connected to both sides of the inclined guide surface 321. The two planes and the inclined guide surface 321 cooperate to form a Z-shaped surface. The two planes correspond to two states (molding and injection, and molding and hooking) to stabilize at the injection position and the hooking position, thereby improving production accuracy.

[0039] The first end of the hook needle 33 is provided with a release head, which includes a truncated cone portion that is small at the end and large in the middle, so as to improve the stability of the hook.

[0040] The second feeding mechanism is located on the third template 13 and includes a second nozzle and a third feeding channel that can connect to the second nozzle. The third feeding channel is arranged perpendicular to the first direction.

[0041] The product molded in this specific embodiment is as follows: Figure 1 , Figure 2 As shown, product 5 includes a first part 51 and a second part 52. The first part 51 and the second part 52 are different colors. Please refer to [the documentation / reference]. Figure 3 , Figure 4 When the mold device is in the mold closing position, the first feeding mechanism 2 and the second feeding mechanism respectively form the first part 51 and the second part 52 to form product 5.

[0042] Please refer to Figure 5 The second template 12 and the third template 13 are separated to remove the feed residue 15 in the first feed channel 22 and the third feed channel 23; please refer to Figure 6 The first template 11 and the second template 12 are separated to extract the first nozzle; please refer to [the documentation / reference]. Figure 7 , Figure 8 , Figure 10 , Figure 11 The piston rod 311 and push block 32 move along the vertical first direction and allow the through groove 332 to slide relative to the hook needle 33. The inclined guide surface 321 acts to engage the head 331 to drive the hook needle 33 to move along the first direction to hook material. Since the hooking effect is good at the connection point, the hooking effect is good.

[0043] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
