Description

Technical Field

[0001] The utility model relates to an injection molding workpiece shaping device, in particular to a square frame workpiece shaping fixture. Background Art

[0002] Taking a square-shaped workpiece as an example, when the injection molded workpiece is taken out of the molding machine after processing and molding, it is easily affected by temperature and bends and deforms. The means of preventing the deformation of the injection molded workpiece in the prior art is to slowly change the temperature of the workpiece. However, this method will cause the injection molding process cycle to be extended, which is not conducive to efficient production. Moreover, after cooling, a large number of workpieces will still be deformed, resulting in a decrease in product yield and failure to meet process requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a square frame workpiece shaping fixture which can realize rapid shaping of frame workpieces, shorten the process cycle, and has a simple structure and is easy to operate, in view of the deficiencies of the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0005] A square workpiece shaping jig comprises a base plate, on which are disposed a plurality of positioning jig assemblies for placing the square workpiece, a plurality of clamping fixtures are disposed adjacent to each positioning jig assembly, a pressing plate is disposed at the clamping end of the clamping fixture, the pressing plate is disposed above two symmetrical frames of the square workpiece, and the pressure applied by the clamping fixture drives the pressing plate to press the square workpiece onto the positioning jig assembly.

[0006] Preferably, the frame workpiece is a rectangular frame, the positioning fixture assembly is a long strip fixture, and a plurality of clamping clamps are evenly distributed along the length direction of the positioning fixture assembly.

[0007] Preferably, the clamping fixture is a horizontal quick-action clamp.

[0008] Preferably, a cushion block is fixed to the bottom of the clamping fixture, and the cushion block is fixedly connected to the base plate.

[0009] Preferably, the positioning fixture assembly includes two end fixture blocks, and the left and right frames of the square workpiece are respectively buckled on the two end fixture blocks.

[0010] Preferably, the positioning fixture assembly includes two side fixture blocks, and the two side fixture blocks are respectively covered on the outer sides of the front and rear frames of the square workpiece.

[0011] In the square frame workpiece shaping jig disclosed by the utility model, a plurality of positioning jig assemblies can be fixed on the bottom plate in a manner of being evenly distributed front and back, and a plurality of groups of clamping fixtures corresponding to the positioning jig assemblies are arranged on the bottom plate, and the number of clamps in each group of clamping fixtures is multiple, and they are evenly distributed along the adjacent parts of the positioning jig assemblies. When the square frame workpiece is loaded on the positioning jig assembly, the positioning jig assembly is used to clamp and position the square frame workpiece, and then the clamping fixture is operated to press the pressure plate on the top of the square frame workpiece. Under the uniform pressure of multiple pressure plates, the square frame workpiece can be ensured to complete cooling and shaping within a certain period. When the entire shaping jig enters the next working cycle, the pressure applied by the clamping fixture is removed, and finally the shaped square frame workpiece is taken out. Based on the above principle, it can be seen that the utility model can not only realize the rapid shaping of the frame workpiece, but also shorten the process cycle without waiting for a long time. At the same time, the utility model has a simple structure, is easy to implement, and is also convenient to operate in practical applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0017] The utility model discloses a square frame workpiece shaping fixture, combined with Figures 1 to 4 As shown, it includes a base plate 1, on which are disposed a plurality of positioning jig assemblies 2 for placing a frame workpiece 100, and adjacent to each positioning jig assembly 2 are disposed a plurality of clamping fixtures 3, and the clamping ends of the clamping fixtures 3 are provided with a pressing plate 4, and the pressing plate 4 is disposed above two symmetrical frames of the frame workpiece 100, and the pressure applied by the clamping fixtures 3 drives the pressing plate 4 to press the frame workpiece 100 onto the positioning jig assembly 2.

[0018] In the above structure, multiple positioning jig assemblies 2 can be fixed on the base plate 1 in a manner of being evenly distributed front and back, and at the same time, multiple groups of clamping fixtures 3 corresponding to the positioning jig assemblies 2 are arranged on the base plate 1, and the number of clamps in each group of clamping fixtures 3 is multiple, and they are evenly distributed along the adjacent parts of the positioning jig assembly 2. When the square workpiece 100 is loaded on the positioning jig assembly 2, the positioning jig assembly 2 is used to clamp and position the square workpiece 100, and then the clamping fixture 3 is operated to press the pressing plate 4 on the top of the square workpiece 100. Under the uniform pressure of multiple pressing plates 4, it can be ensured that the square workpiece 100 is cooled and formed within a certain period of time. When the entire forming jig enters the next working cycle, the pressure applied by the clamping fixture 3 is released, and finally the formed square workpiece 100 is taken out. Based on the above principle, it can be seen that the utility model can not only realize the rapid shaping of the frame workpiece, but also shorten the process cycle without waiting for a long time. At the same time, the utility model has a simple structure, is easy to implement, and is also convenient to operate in practical applications.

Specifically, a plurality of clamping clamps 3 are evenly distributed on the same side of the positioning fixture assembly 2.

[0020] As a preferred embodiment, the clamping fixture 3 is a horizontal quick clamp, which has the characteristics of self-limiting and convenient opening and closing operations, and is therefore suitable as the pressure mechanism in this embodiment.

[0021] See also Figure 4 In order to ensure that the height of the pressing plate 4 matches the height of the frame workpiece 100 , in this embodiment, a cushion block 5 is fixed to the bottom of the clamping fixture 3 , and the cushion block 5 is fixedly connected to the base plate 1 .

[0022] See also Figure 3 In this embodiment, the positioning fixture assembly 2 includes two end fixture blocks 20, and the left and right frames of the square workpiece 100 are respectively buckled on the two end fixture blocks 20. Further, the positioning fixture assembly 2 includes two side fixture blocks 21, and the two side fixture blocks 21 are respectively covered on the outer sides of the front and rear frames of the square workpiece 100.
