Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection molding mold for a motorcycle frame. Background Technology

[0002] A motorcycle frame injection molding die is a type of mold used for injection molding motorcycle frame structures.

[0003] Based on the above, the inventors have discovered that there are many injection molding molds for motorcycle frames on the market. However, in general, after the injection molding process is completed and the mold cools, workers manually separate the upper and lower modules using a spatula. This requires workers to physically disassemble the mold, which easily causes wear and tear on the molded parts inside. Furthermore, it requires workers to expend a lot of effort to separate the parts, reducing the effectiveness of the device. Therefore, in view of this, the inventors have researched and improved the existing structure to provide an injection molding mold for motorcycle frames, aiming to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a motorcycle frame injection molding mold, including a lower module, an upper module at the top of the lower module, a separation mechanism at the bottom of the lower module, and a pushing mechanism on the outer wall of the lower module.

[0006] The separation mechanism includes:

[0007] The base plate has its top end fixed to the bottom end of the lower module. A hydraulic cylinder is fixed to the outer wall of the base plate. A square plate is fixed to the output shaft of the hydraulic cylinder. The square plate is located at the bottom end of the lower module. Four connecting columns are fixed to the top end of the square plate. The inner wall of the lower module slides against the outer wall of the connecting columns.

[0008] As a preferred embodiment of this utility model, the lower module has grooves on both sides, and the inner walls of the two grooves are provided with push plates, which are located at the bottom of the upper module.

[0009] As a preferred embodiment of this utility model, the inner wall of the upper module is fitted with four pillars, and the bottom ends of the four pillars are fixed to the top end of the lower module.

[0010] As a preferred embodiment of this utility model, both sides of the square plate are provided with concave plates, and the tops of the two concave plates slide against the outer wall of the push plate.

[0011] As a preferred embodiment of this utility model, a block is fixed to one side of each of the two concave plates, and square grooves are provided on both sides of each square plate. The inner walls of the two square grooves are matched with the outer walls of the blocks.

[0012] As a preferred embodiment of this utility model, the driving mechanism includes:

[0013] Two slot blocks are provided, the bottom ends of which are fixed to the outer wall of the lower module. Spring dampers are fixed to the bottom ends of the inner walls of the two slot blocks. Sliding columns are provided at the top ends of the two spring dampers. The outer walls of the two sliding columns slide against the inner walls of the slot blocks. Connecting plates are fixed to both sides of the upper module. The bottom ends of the two connecting plates are fixed to the top ends of the sliding columns.

[0014] As a preferred embodiment of this utility model, the inner walls of both sliding columns are fitted with insert plates, and the outer walls of both insert plates are fitted with the inner walls of the groove block.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution involves closing the upper and lower modules, allowing the inner wall of the upper module to slide against the outer wall of the support column. A sliding post fixed at the bottom of the connecting plate rests on the inner wall of the groove, allowing the compression spring damper to contract and move within the groove. After the motorcycle frame material is injected into the mold and cooled, a hydraulic cylinder drives a square plate to move up and down at the bottom of the lower module. This causes the connecting post fixed at the top of the square plate to fit within the inner wall of the lower module, separating the bottom of the upper module from the top of the lower module. Two concave plates are installed on one side of the square plate, with a block fixed to one side of the concave plate inserted into the inner wall of the square groove, ensuring a tight fit between the concave and square plates. As the square plate moves up and down, the concave plates apply upward and downward external forces to the push plate, further separating the sides of the upper module from the top of the lower module. This avoids manual disassembly by workers, preventing wear on the injection-molded parts inside the mold, and allows for quick removal of the injection-molded motorcycle frame from the mold.

[0017] 2. In this solution, the outer walls of the two insert plates are respectively fitted onto the inner wall of the slot block, so that one side of the insert plate is separated from the inner wall of the sliding column. When the upper module and the lower module are separated at the edge, the reset driving force of the spring damper pushes the sliding column to slide on the inner wall of the slot block, thus driving the upper module to slide on the outer wall of the support column. This allows the workers to quickly separate the upper module from the top of the lower module, which is convenient for the normal use of the device. Attached Figure Description

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figures 1-5 As shown, this utility model provides a motorcycle frame injection molding mold, which includes a lower module 1, an upper module 2 at the top of the lower module 1, a separation mechanism 3 at the bottom of the lower module 1, and a pushing mechanism 4 on the outer wall of the lower module 1.

[0027] Separation mechanism 3 includes:

[0028] The base plate 31 is fixed at its top end to the bottom end of the lower module 1. A hydraulic cylinder 32 is fixed on the outer wall of the base plate 31. A square plate 33 is fixed on the output shaft of the hydraulic cylinder 32. The square plate 33 is located at the bottom end of the lower module 1. Four connecting columns 34 are fixed at the top end of the square plate 33. The inner wall of the lower module 1 slides against the outer wall of the connecting columns 34.

[0029] As attached Figure 1As shown, grooves 5 are provided on both sides of the lower module 1, and push plates 6 are provided on the inner walls of both grooves 5. Both push plates 6 are located at the bottom of the upper module 2. Concave plates 35 are provided on both sides of the square plate 33, and the tops of both concave plates 35 slide against the outer walls of the push plates 6. A block 36 is fixed to one side of each of the two concave plates 35. Square grooves 37 are provided on both sides of the square plate 33, and the inner walls of both square grooves 37 are matched with the outer walls of the block 36, which facilitates the slow separation of the upper module 2 from the top of the lower module 1.

[0030] As attached Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the upper module 2 is fitted with four support pillars 7, and the bottom ends of the four support pillars 7 are fixed to the top end of the lower module 1, which facilitates better separation between the upper module 2 and the lower module 1.

[0031] As attached Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the driving mechanism 4 includes:

[0032] Two slot blocks 41 are fixed at their bottom ends to the outer wall of the lower module 1. Spring dampers 42 are fixed at the bottom ends of the inner walls of the two slot blocks 41. Sliding columns 43 are provided at the top ends of the two spring dampers 42. The outer walls of the two sliding columns 43 slide against the inner walls of the slot blocks 41. Connecting plates 44 are fixed on both sides of the upper module 2. The bottom ends of the two connecting plates 44 are fixed to the top ends of the sliding columns 43. Insert plates 45 are fitted on the inner walls of the two sliding columns 43. The outer walls of the two insert plates 45 fit against the inner walls of the slot blocks 41, which facilitates the sliding of the upper module 2 on the outer wall of the support column 7, thus allowing the workers to quickly separate the upper module 2 from the top of the lower module 1.

[0033] Working principle: During use, the upper module 2 and lower module 1 are closed, causing the inner wall of the upper module 2 to slide against the outer wall of the support column 7. The sliding column 43 fixed at the bottom of the connecting plate 44 is on the inner wall of the groove block 41, so that the compression spring damper 42 can contract and move on the inner wall of the groove block 41. After the motorcycle frame material is injected into the mold and cooled and formed, the hydraulic cylinder 32 drives the square plate 33 to move up and down at the bottom of the lower module 1 on the outer wall of the base plate 31, so that the connecting column 34 fixed at the top of the square plate 33 is sleeved on the inner wall of the lower module 1, so as to drive the bottom of the upper module 2 to separate from the top of the lower module 1. Two concave plates 35 are installed on one side of the square plate 33, so that the square block 36 fixed on one side of the concave plate 35 is inserted into the inner wall of the square groove 37, so that the concave plate 35 and the square plate 33 are tightly connected. The fixed installation, and then the square plate 33 moves up and down while the concave plate 35 applies an external force to the push plate 6, further separating the two sides of the upper module 2 from the top of the lower module 1, avoiding manual and violent disassembly by the staff, so as to avoid wear on the injection-molded objects inside the mold, thereby quickly removing the injection-molded motorcycle frame from the mold. The outer walls of the two insert plates 45 are respectively fitted onto the inner wall of the groove block 41, so that one side of the insert plate 45 separates from the inner wall of the slide column 43. When the upper module 2 separates from the edge of the lower module 1, the reset driving force of the spring damper 42 pushes the slide column 43 to slide on the inner wall of the groove block 41, thus driving the upper module 2 to slide on the outer wall of the support column 7, so that the staff can quickly separate the upper module 2 from the top of the lower module 1.
