Description

Technical Field

[0001] This utility model relates to the field of rubber parts manufacturing technology, specifically a fully automatic mold opening and closing clamping fixture for multi-specification rubber molds. Background Technology

[0002] In the field of aerospace rubber product manufacturing, compression molding is often used to process and manufacture rubber products. Compression molding vulcanization refers to the process of refining the rubber compound, cutting it into blanks, placing them into the mold cavity, closing the mold, and then pressing and heating it through a flat vulcanizing machine, controlling the vulcanization time to prepare the product.

[0003] Chinese patent application CN114179264A discloses an automatic mold opening and closing mechanism for a vulcanizing machine. Through the design of a support plate, lead screw, horizontal plate, electric push rod, insert rod, notch, and nozzle, the mechanism works as follows: During mold closing, the raw material is laid on the bottom mold. The motor drives the horizontal plate downwards via the lead screw. The horizontal plate, through the insert rod, lowers the top mold onto the bottom mold, ensuring that the limiting groove of the top mold and the limiting post of the bottom mold engage to prevent slippage. Then, the electric push rod drives the insert rod to sequentially disengage from the insertion holes on both sides of the top mold, thus completing the mold closing process. During mold opening, the bottom mold moves to the notch of the side clamping plate. The electric push rod drives the insert rod to insert into the insertion hole of the top mold. Then, the lead screw drives the top mold to rise steadily via the horizontal plate, completing the mold opening process. This method forms an automatic mold opening and closing mechanism for molding dies.

[0004] However, the automatic mold opening and closing structure designed in this patent is simple. The upper and lower mold plates are directly fixed and locked to the vulcanizing machine by metal rods. It is only suitable for the manufacture of molds with a single external shape and for the manufacture of rubber parts of a very large batch with a single size. It cannot be used for clamping molds of different specifications and models, and cannot realize the automated opening and closing of molds of various sizes. However, aerospace rubber products are characterized by small batches and multiple varieties, involving thousands of different sets of molds for molding rubber products. The molds have different external shapes and sizes. The traditional opening and closing operation of aerospace rubber molds requires the operator to use a screwdriver to forcefully open the upper mold plate of different sizes of molds. After completing the part removal and loading operation, the upper mold plate must be manually lifted again to cover the lower mold plate to complete the mold closing operation. Rubber molds are very bulky, the whole process is time-consuming and labor-intensive, and the production efficiency is low. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a fully automatic mold opening and closing clamping fixture for multi-specification rubber molds. It connects molds of different sizes and specifications, and locks the upper mold plate and upper fixed plate, as well as the lower mold plate and lower fixed plate, respectively. Finally, under the force of the vulcanizing machine's lifting mechanism, the upper and lower mold plates are automatically opened and closed, improving production efficiency.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A fully automatic mold opening and closing clamping fixture for multi-specification rubber molds includes an upper fixed plate, a lower fixed plate, an upper mold template located at the bottom of the upper fixed plate, and a lower mold template located above the lower fixed plate. Four upper clamps for fixing the upper mold template are arranged around the perimeter of the upper fixed plate. The four upper clamps can be adjusted in position along the diagonal direction of the upper mold template to accommodate molds of different specifications. Similarly, four lower clamps for fixing the lower mold template are arranged around the perimeter of the lower fixed plate. The four lower clamps can also be adjusted in position along the diagonal direction of the lower mold template to accommodate molds of different specifications.

[0008] As a further improvement of this utility model, four upper adjustment holes are provided at a 45° angle around the upper fixing plate.

[0009] As a further improvement of this utility model, four downward adjustment holes are provided at a 45° angle around the lower fixing plate, and the positions of the downward adjustment holes correspond vertically to those of the upward adjustment holes.

[0010] As a further improvement of this utility model, both the upper clamp and the lower clamp include an L-shaped fixing block with a hole, a bolt that cooperates with the L-shaped fixing block with a hole, and a nut that cooperates with the bolt.

[0011] As a further improvement of this utility model, the bolt in the upper clamp is adapted to the upper adjusting hole.

[0012] As a further improvement of this utility model, the bolt in the lower clamp is adapted to the lower adjusting hole.

[0013] As a further improvement of this utility model, both the upper clamp and the lower clamp have L-shaped perforated fixing blocks provided with clamp adjustment holes.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a fully automatic mold opening and closing clamping fixture for multi-specification rubber molds.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 7 As shown, a fully automatic mold opening and closing clamping fixture for multi-specification rubber molds includes an upper fixed plate 1, an upper clamp 2, a lower clamp 3, a lower fixed plate 4, an upper mold template 6, and a lower mold template 7. In... Figure 2 In the mold-closed state shown, a mold cavity 5 is formed between the upper mold plate 6 and the lower mold plate 7. The upper clamp 2 is used to fix the upper mold plate 6 to the bottom of the upper fixing plate 1, and the lower clamp 3 is used to fix the lower mold plate 7 to the top of the lower fixing plate 4.

[0027] The upper fixing plate 1 has four upper adjustment holes 11 arranged at a 45° angle around its perimeter, and the lower fixing plate 4 has four lower adjustment holes 41 arranged at a 45° angle around its perimeter. The four lower adjustment holes 41 are vertically aligned with the four upper adjustment holes 11. Both the upper adjustment holes 11 and the lower adjustment holes 41 are elongated circular holes.

[0028] Four upper clamps 2 and four lower clamps 3 are provided. The four upper clamps 2 are correspondingly disposed in the four upper adjustment holes 11 on the upper fixed plate 1, and the positions of the upper clamps 2 can be adjusted along the upper adjustment holes 11 to accommodate molds of different sizes. The four lower clamps 3 are correspondingly disposed in the four lower adjustment holes 41 on the lower fixed plate 4, and the positions of the lower clamps 3 can be adjusted along the lower adjustment holes 41 to accommodate molds of different sizes.

[0029] Each upper clamp 2 and each lower clamp 3 includes an L-shaped fixing block 8 with a hole, a nut 9, and a bolt 10. The L-shaped fixing block 8 with a hole is provided with a clamp adjustment hole 81. After the bolt 10 on the upper clamp 2 passes through the upper adjustment hole 11 and the clamp adjustment hole 81 on the L-shaped fixing block 8, its end is screwed into the nut 9 to achieve a fixed connection with the upper fixing plate 1, and at the same time, the upper template 6 of the mold is clamped and fixed by the L-shaped fixing block 8. Similarly, after the bolt 10 on the lower clamp 3 passes through the lower adjustment hole 41 and the clamp adjustment hole 81 on the L-shaped fixing block 8, its end is screwed into the nut 9 to achieve a fixed connection with the lower fixing plate 4, and at the same time, the lower template 7 of the mold is clamped and fixed by the L-shaped fixing block 8.

[0030] Working principle and usage process of this utility model:

[0031] In use, depending on the different external dimensions of the mold to be clamped, in the mold-closed state, first use four lower clamps 3, adjusting their positions in the lower adjustment hole 41 and the clamp adjustment hole 81 of the L-shaped fixed block 8 on the lower clamp 3 using bolts 10 and nuts 9, and lock them to the lower fixed plate 4 and the lower mold template 7. Then use four upper clamps 2, adjusting their positions in the upper adjustment hole 11 and the clamp adjustment hole 81 of the L-shaped fixed block 8 on the upper clamp 2 using bolts 10 and nuts 9, and lock them to the upper fixed plate 1 and the upper mold template 6. Next, the vulcanizing machine lifting mechanism is connected to the upper fixed plate 1. After clamping the mold according to the above steps, open the mold opening switch. Under the action of the lifting mechanism, the upper mold template 6 can be locked and lifted by the upper fixed plate 1 to realize the mold opening operation. Open the mold closing switch, and the upper mold template 6 can be locked by the upper fixed plate 1 and lowered until it is completely matched with the lower mold template 7 to realize the mold closing operation. By designing and using a fully automatic mold opening and closing clamping fixture for rubber molds, the fully automatic opening and closing of molds of different shapes and sizes can be achieved.
