Automatic ejection mechanism for arc products

Abstract

The invention discloses an automatic demoulding mechanism for arc products. The portion, at a first connection end (1-2), in a mold is provided with a buckle demoulding mechanism and a first connection end core-pulling mechanism. The portion, at a side branch pipe (1-5), in the mold is provided with a side branch pipe core-pulling mechanism and an axial shoulder demoulding mechanism. The portion,at an arc pipe (1-1), in the mold is provided with an arc core-pulling mechanism. The portion, at a second connection end (1-3), in the mold is provided with a second connection end core-pulling mechanism. Demoulding of the buckle demoulding mechanism and core-pulling of the side branch pipe core-pulling mechanism are driven while mold opening of an upper mold plate. Demoulding of the axial shoulder demoulding mechanism is driven by the movement of the side branch pipe core-pulling mechanism. According to the automatic demoulding mechanism, by adoption of the structure, the size of the entiremold is greatly reduced, the number of parts is small, the structure is simple, a demoulding order of each core is precisely controlled, and the rejection rate of product production is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an automatic demoulding mechanism for circular arc products. Background technique [0002] At present, plastic products are more and more widely used in our daily life and production, and the production of these plastic products is produced through plastic molds. For example, products with curved sections such as plastic connecting elbows, such as attached figure 1 As shown in , the middle part of the connecting elbow 1 is an arc tube 1-1, and the two ends of the arc tube 1-1 are the first joint end 1-2 and the second joint end 1-3, and each joint end arc The joints of the shaped pipes 1-1 all have a section of straight pipe, and the outer peripheral wall of the first joint end 1-2 has buckles 1-4, and the outer peripheral wall of the arc-shaped pipe 1-1 is also connected with the internal The channel is connected to the side branch pipe 1-5, and the outer peripheral wall of the ...

Problems solved by technology

Therefore, to complete the demoulding process of these numerous structures, as far as the production mold of the prior art is concerned, either it cannot be realized, or the volume of the whole mold is greatly increased, and the structure is very complicated. Actions in sequence, the demoulding and scrapping rate of the product is extremely high
