Description
Technical Field
The utility model relates to an injection mold field, especially a skylight of trilateral back-off hold-down mechanism for the shaping of goods of borduring.
Background
The automobile skylight product comprises a central glass part, wherein glue injection molding is needed to be carried out on the periphery of the glass part, and finally the required product is obtained. Generally, skylight products are all-around inverted buckles, sliding block structures need to be designed on four edges of products during all-around inverted buckles, the force application directions of each pair of sliding block structures are opposite, and the pulling force between the sliding block structures can be mutually counteracted during die opening. However, a three-sided reverse-locking or a one-sided reverse-locking condition may be encountered, for example, the rear half of the panoramic sunroof is a three-sided reverse-locking product.
When three sides are reversed, three sliding blocks need to be designed, so that tension force is not generated on one independent sliding block in the opposite direction to offset the force of the sliding block, the product is easy to move in a cavity when the mold is opened, and once the product moves relative to the cavity, the side wall of the product can generate defects such as cutting and the like due to the relative displacement.
Conventionally, an oil cylinder is adopted to drive a pressing block to press a product, and although the oil cylinder can provide a large pressing force, once an oil way system of the oil cylinder leaks, fouling of a mold and the product can be caused. For some enterprises with low requirements, it is enough to directly select the oil cylinder to drive the compression block, but for some enterprises with high requirements on product quality, the oil cylinder is hoped to be replaced by the same product.
If the air cylinder is used for providing pressing force, although the problem can be solved to a certain degree, the pressing force provided by the air cylinder is limited, and the product cannot be kept still.
There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, low cost can guarantee the goods rigidity when the die sinking, and the skylight that has trilateral back-off that just can not have hidden danger such as hydraulic oil reveals that the goods shaping is used hold-down mechanism bordures.
The technical solution of the utility model is that: the utility model provides a skylight is bordured packagine product shaping and is used hold-down mechanism with trilateral back-off which characterized in that: the pressing mechanism comprises a fixed seat 2 fixedly arranged on a template 1, wherein a first connecting rod 3 is connected to the fixed seat 2 in a swinging mode, one end of the first connecting rod 3 is connected with one end of a second connecting rod 5 in a rotating mode through a rotating shaft 4, a straight ejection cylinder 6 is further arranged on the template 1, a working shaft of the straight ejection cylinder 6 is located under the rotating shaft 4 and can be in contact with the bottom end of the joint of the first connecting rod 3 and the second connecting rod 5, a rotary cylinder 7 is further arranged on the template 1, a pressing swinging force arm 8 is arranged at the working end of the rotary cylinder 7, one end of the pressing swinging force arm 8 is provided with a pressing block 9, and the other end of the pressing swinging force arm 8 is rotatably connected with one end, far away from the rotating shaft 4, of the second connecting rod 5.
Compared with the prior art, the utility model, have following advantage:
the pressing mechanism for forming the skylight edging product with the three-side reverse buckle in the structural form has the advantages of simple structure, ingenious design and reasonable layout, and designs a special pressing structure aiming at various problems existing in the process of preparing the edging product with the asymmetric reverse buckle structure. This structure utilizes revolving cylinder as the power supply, and supplementary with one set of link mechanism through the control of straight top cylinder, utilize straight top cylinder and link mechanism to increase revolving cylinder's effort to the compact heap to under the prerequisite that utilizes the cylinder as the power supply, for the compact heap provides sufficient packing force, guarantee that goods can not take place the drunkenness at the forced-release in-process. The oil cylinder is not used as a power source, so that hidden dangers such as leakage and pollution of hydraulic oil are avoided, and meanwhile, enough pressure can be provided. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: the utility model provides a skylight is bordured goods forming and is used hold-down mechanism with trilateral back-off, is including fixed fixing base 2 that sets up on template 1, swing on fixing base 2 is connected with first connecting rod 3, and the one end of first connecting rod 3 is rotated through pivot 4 and the one end of second connecting rod 5 and is connected, still is provided with straight top cylinder 6 on template 1, the working shaft of straight top cylinder 6 is located pivot 4 under to can be in the bottom contact of first connecting rod 3 and the 5 junction of second connecting rod, still be provided with revolving cylinder 7 on template 1, be provided with down on revolving cylinder 7's the working end and press the swing arm of force 8, the one end of pushing down swing arm of force 8 is provided with compact heap 9, and the other end of pushing down swing arm of force 8 then rotates with the one end that second connecting rod 5 kept away from pivot 4 and is connected.
The utility model discloses skylight that has trilateral back-off is bordured goods hold-down mechanism for shaping's working process as follows: when a product needs to be compressed, firstly, a control system sends an instruction to control the rotary cylinder 7 to work, the rotary cylinder 7 drives the downward pressing swinging force arm 8 to act, and the pressing block 9 at the end part of the downward pressing swinging force arm 8 moves downward and presses the glass part of the product;
meanwhile, the control system controls the straight jacking cylinder 6 to work, because the working shaft of the straight jacking cylinder 6 is positioned right below the rotating shaft 4, the straight jacking cylinder 6 can push the rotating shaft 4 to move upwards, because the first connecting rod 3 and the second connecting rod 5 are connected through the rotating shaft 4, the hinge point (the rotating shaft 4) of the first connecting rod 3 and the second connecting rod 5 moves upwards and can simultaneously drive the first connecting rod and the second connecting rod to swing, after the second connecting rod 5 which has a relatively large inclination angle with the horizontal direction swings, the included angle between the second connecting rod and the horizontal direction becomes small, because the other end of the first connecting rod 3 is the fixed seat 2, the action finally drives one end, far away from the rotating shaft 4, of the second connecting rod 5 to jack the pressing force arm 8 of the pressing swing arm 8 against the pressing block 9, and the transmission of the force is increased;
when the glass part needs to be loosened, the straight jacking cylinder 6 is recovered, and the rotating cylinder 7 drives the downward pressing swinging force arm 8 to swing reversely.
It should be noted that even if the working shaft of the cylinder block 6 is in the extended extreme position, the axes of the first connecting rod 3 and the second connecting rod 5 are not collinear, but have a certain included angle, which might otherwise affect the return of the first connecting rod 3 and the second connecting rod 5.
