Description

Technical Field

[0001] The utility model relates to the technical field of plastic and metal forming machines, in particular to a safety door guide rail structure for plastic and metal forming machines. Background Art

[0002] In the daily operation of the molding machine, the operator needs to frequently open and close the movable door weighing more than 40kg in order to change the mold and / or remove the product. This process mainly relies on the guide rail structure to support the weight. Long-term repeated actions make the guide rail structure prone to fatigue deformation and wear, which will change the gap between the pulley and the guide rail, thus affecting the stable operation and life of the safety door.

[0003] At present, the common guide rail solutions on the market are: integral aluminum castings and I-beams and other profiles as guide rails. Although the stability performance meets the requirements, the cost is high, and these designs lack flexible adjustment mechanisms. Once there is a problem with the gap between the pulley and the guide rail, it cannot be effectively adjusted, which is not conducive to quickly adapting to the needs of maintenance or adjustment.

[0004] In view of this, a new safety door guide rail structure with a more reasonable structure, lower cost and the ability to easily adjust the gap between the pulley and the guide rail is needed to meet the needs of safe and efficient operation of the molding machine. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a safety door guide rail structure for plastic and metal molding machines, which is a new safety door guide rail structure with a more reasonable structure, lower cost and convenient adjustment of the gap between the pulley and the guide rail.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] A safety door guide rail structure for a plastic or metal forming machine, comprising:

[0008] A pair of guide plates are provided in mirror images on the upper and lower sides; the guide plates are formed by stamping and bending a flat plate, the cross section of the guide plates is an open pattern, the upper open pattern extends from right to left, is bent upwards 90° for the first time, is bent rightwards 90° for the second time, and is bent downwards 90° for the third time, and a V-shaped groove that is concave to the inner side of the guide plates is formed on the plate body formed by the second bending of the guide plates;

[0009] An interval adjustment structure, wherein the opposite side plates of the two guide rail plates are connected via the interval adjustment structure;

[0010] Two seamless steel pipes are provided and are fixed in two V-shaped grooves respectively.

[0011] As an improvement, the interval adjustment structure includes a bolt, a nut 1 and a nut 2; through holes for the bolts to pass through are reserved on the opposite side plates of the two guide rail plates, and after the nut 1 and the nut 2 are respectively threaded onto the bolts, the top plate of the lower guide rail plate is clamped and fixed between the nut 1 and the nut 2. The interval between the two guide rail plates can be adjusted.

[0012] The advantages of the utility model compared with the prior art are:

[0013] 1. Operation efficiency: Through the implementation of this new model, the maintenance and adjustment time can be significantly reduced. The better adjustment function of this new model enables the safety door to adapt to different working conditions, thereby improving the overall operation efficiency and production continuity;

[0014] 2. Cost-effectiveness: Compared with the traditional integral guide rail, the segmented design and adjustability of this new type significantly reduce the production and maintenance costs. The use of precision-bent guide rail plates and standardized seamless steel pipes also reduces material waste and processing costs, and enhances the market competitiveness of the overall structure;

[0015] 3. Reliability and safety: The V-groove structure of the guide plate and the MIG welding connection of the seamless steel pipe ensure the reliable operation of the safety door. In addition, the improved adjustability reduces the wear or deformation of the guide structure, effectively reduces safety risks and extends the service life of the equipment.
