Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to a mold which is convenient for mold closing. Background Art

[0002] Moulds are various tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts.

[0003] When existing molds are mated, workers usually need to manually close the molds. Since the upper mold has too much gravity, it will move downward relatively quickly, causing a slight collision when mating with the lower mold, which can easily cause certain scratches on the upper and lower molds. In serious cases, the molds will be damaged, resulting in economic losses. Utility Model Content

[0004] The purpose of the utility model is to provide a mold that is convenient for mold closing. A deceleration component is set, specifically, a clamping block is brought close to a fixed seat to drive the friction block to contact the fixed column. The continuous movement of the clamping block will squeeze the spring 2, and then the friction block is tightly attached to the outer surface of the fixed column under the elastic action of the spring 2, thereby increasing the friction force and reducing the moving speed. It can avoid the situation where the upper mold collides when the moving speed is too fast, and effectively protect the lower mold and the upper mold from damage. It solves the problem that the staff usually need to manually close the mold when the existing mold is matched. Since the upper mold has too much gravity itself, it will move downward relatively quickly, and a slight collision will occur when it matches with the lower mold, which is easy to cause certain scratches on the upper and lower molds, and even cause damage to the mold in serious cases.

The surface is fixedly connected to the inner wall of the friction block 132, and a deceleration component 13 is set, specifically, the clamping block 131 is close to the fixed seat 133, so as to drive the friction block 132 to contact with the fixed column 14. The continuous movement of the clamping block 131 will squeeze the spring 2 322, and then the friction block 132 is tightly attached to the outer surface of the fixed column 14 under the elastic action of the spring 2 322, thereby increasing the friction force and reducing the moving speed, which can avoid the upper mold 12 from colliding when the moving speed is too fast, and effectively protect the lower mold 11 and the upper mold 12 from damage. The top of the upper mold 12 is fixedly connected to the top plate 121, and the top of the top plate 121 is fixedly connected to the hydraulic cylinder 122. The four corners of the bottom of the upper mold 12 are fixedly connected to the positioning blocks 123, and the positioning blocks 123 are used to The upper mold 12 and the lower mold 11 play a positioning role, so that the mold closing is more accurate. The bottom of the top plate 121 is fixedly connected to a fixed seat 133, and a push rod 134 is arranged below the fixed seat 133. The top of the push rod 134 is fixedly connected to a connecting rod 341. By setting the push rod 134, specifically, the hydraulic cylinder 122 drives the connecting rod 341 to be stored upward, then the connecting rod 341 drives the push rod 134 to move upward together. Since the bottom of the fixed block 311 is arranged as an inclined surface, the push rod 134 will drive the clamping block 131 to approach the fixed seat 133 through the fixed block 311. By driving the push rod 134 to move different distances, the friction between the friction block 132 and the fixed column 14 can be adjusted, so that the appropriate friction force can be adjusted, which is convenient for operation.

The connecting rod 341 is slidably connected to the top plate 121 and the fixing seat 133 respectively. Starting the hydraulic cylinder 122 drives the connecting rod 341 to move upward or downward, which can make the push rod 134 move upward or downward, thereby pushing or moving away from the fixing block 311.

[0029] A specific application of this embodiment is:

[0030] When it is necessary to close the lower mold 11 and the upper mold 12, the hydraulic cylinder 122 is started to drive the connecting rod 341 to be stored upward, and the connecting rod 341 drives the push rod 134 to move upward together. Since the bottom of the fixing block 311 is set with an inclined surface, the push rod 134 will push the fixing block 311, and the fixing block 311 will slide on the fixing rod 312 and squeeze the spring 1 313. The fixing block 311 drives the clamping block 131 to approach the fixing seat 133, so that the friction block 132 contacts the outer surface of the fixing column 14, and the continuous movement of the clamping block 131 will squeeze the spring 2 322, and the limiting rod 321 slides on the clamping block 131, and then the friction block 132 is tightly attached to the outer surface of the fixing column 14 under the elastic action of the spring 2 322, and then the upper mold 12 is pushed downward, which can be The friction between the wiping block 132 and the fixed column 14 increases the friction force, so that the upper mold 12 moves slowly downward, and the upper mold 12 will slide on the stabilizing rod 15 through the top plate 121. When the positioning block 123 is plugged into the top of the lower mold 11 and the bottom of the upper mold 12 contacts the top of the lower mold 11, the mold closing is completed, which can avoid the situation of collision caused by excessive movement speed and effectively protect the lower mold 11 and the upper mold 12 from damage. When the two need to be opened, the hydraulic cylinder 122 is started to drive the connecting rod 341 to move downward, and the push rod 134 moves downward, and the fixed block 311 is reset away from the fixed seat 133 under the elastic action of the spring 313. At the same time, the clamping block 131 is reset, and the friction block 132 is not tightly attached to the fixed column 14, so the upper mold 12 can be quickly pulled upward to open the two.
