Description

Technical Field

[0001] This utility model relates to the technical field of material head shearing equipment, and in particular to a semi-automatic four-bar linkage material head shearing fixture. Background Technology

[0002] Currently, in the injection molding industry, after the product is molded, there are many burrs on its edges, which require trimming of the sprue. With the diversification of injection molded products, the trimming of the sprue has become more complicated. Most of the existing sprue trimming is done manually, which is difficult and results in low cutting efficiency.

[0003] The prior art CN207290795U discloses a cutting fixture for injection molding machine sprue products. By setting a fixture base plate, one or more pneumatic clamps and multiple vacuum suction cups, the pneumatic clamps can clamp the sprue head, and the vacuum suction cups can firmly adsorb the product, thereby facilitating manual trimming of the product sprue head and improving cutting efficiency.

[0004] However, the aforementioned shearing fixture cannot automatically trim the product head, and manual trimming with sprue pliers is still required. This results in inconsistent product quality after manual trimming, with frequent occurrences of defects such as product damage, dents, missing material, and high-legged product heads. Utility Model Content

[0005] The purpose of this utility model is to provide a semi-automatic four-link cutting tool for cutting product heads, which aims to solve the technical problem that existing cutting tools cannot achieve automatic trimming of product heads, and still require manual trimming with sprue pliers. As a result, the quality of manually trimmed products cannot be guaranteed, and defects such as product damage, dents, missing material, and high-legged product heads often occur.

[0006] To achieve the above objectives, this utility model provides a semi-automatic four-bar linkage shearing fixture, including a support frame, a fixture table, a contouring fixture, a clamping mechanism, a four-bar linkage, and a shearing mechanism. The fixture table is mounted on the support frame. The contouring fixture, the clamping mechanism, the four-bar linkage, and the shearing mechanism are all mounted on the fixture table. The contouring fixture matches the shape of the product and is used to load the product. The clamping mechanism is located outside the contouring fixture and is used to clamp the product. The four-bar linkage is manually pushed to drive the shearing mechanism to move back and forth. The shearing mechanism is connected to the four-bar linkage and is used to shear the product head.

[0007] The semi-automatic four-bar linkage shearing fixture also includes a waste receiving mechanism, which is located below the fixture table and is used to collect and process the waste obtained from shearing.

[0008] The clamping mechanism consists of two parts, which are respectively located on the front and rear sides of the contouring fixture.

[0009] The shearing mechanism is a shearing blade, and the blade head of the shearing blade is designed to be detachable so as to quickly replace the blade head after it is worn.

[0010] The contouring fixture is detachable to enable the semi-automatic four-bar linkage shearing fixture to shear the heads of similar products.

[0011] This utility model discloses a semi-automatic four-bar linkage shearing fixture. The fixture table is mounted on a support frame. A contouring fixture, a clamping mechanism, a four-bar linkage, and a shearing mechanism are all mounted on the fixture table. The contouring fixture matches the shape of the product and is used to load the product. The clamping mechanism is located outside the contouring fixture and is used to clamp the product. The four-bar linkage is manually pushed to drive the shearing mechanism to move back and forth. The shearing mechanism is connected to the four-bar linkage and is used to shear the product head. By incorporating a detachable contouring fixture, this shearing fixture can shear the heads of similar products, thereby improving its applicability. During shearing, the product is placed into the… The product is clamped within the contouring fixture using the clamping mechanism. Then, the four-bar linkage is manually pushed, transmitting driving force to the linear guide rail, which in turn propels the shearing mechanism forward, cutting off the product's material head. This achieves semi-automatic shearing of the product's material head. Throughout the shearing process, only the four-bar linkage needs to be manually pushed; manual trimming with sprue pliers is unnecessary, reducing the workload for workers. Simultaneously, it meets the precision requirements for material head trimming, ensuring product quality and improving the product pass rate. Furthermore, since the entire shearing process is semi-automatic, compared to fully automated operation, it reduces equipment operating costs while maintaining the precision required for material head trimming, making it more suitable for small-scale factories.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] First Embodiment

[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the semi-automatic four-bar linkage shearing fixture according to the first embodiment of this utility model. Figure 2 This is a schematic diagram showing the connection between the shearing mechanism 106 and the four-bar linkage 105 of the semi-automatic four-bar linkage shearing fixture according to the first embodiment of this utility model. Figure 3 This is a top view of the semi-automatic four-bar linkage shearing fixture of the first embodiment of this utility model.

[0020] This utility model provides a semi-automatic four-bar linkage sprue shearing fixture, comprising a support frame 101, a fixture table 102, a contouring fixture 103, a clamping mechanism 104, a four-bar linkage 105, a shearing mechanism 106, and a waste material receiving mechanism 107. This solution solves the problem that existing shearing fixtures cannot automatically trim product sprues, still requiring manual trimming. This results in inconsistent product quality after manual trimming, with frequent defects such as dents, bumps, insufficient trimming, and high-legged sprues. It is understood that this solution can be used in the injection molding industry for trimming the sprues of injection-molded products.

[0021] In this embodiment, by providing the detachable contouring fixture 103, the material head shearing fixture can shear the material heads of similar products, thereby improving the applicability of the material head shearing fixture. During shearing, the product is placed into the contouring fixture 103 and clamped by the clamping mechanism 104. Then, the four-bar linkage 105 is manually pushed, which transmits the driving force to the linear guide rail, thereby pushing the shearing mechanism 106 forward to shear off the material head of the product. This achieves semi-automatic shearing of the product material head. During the entire shearing process, only the four-bar linkage 105 needs to be manually pushed, eliminating the need for manual trimming with sprue pliers, thus reducing the labor intensity of the workers. At the same time, it can meet the precision requirements of product material head trimming, thereby ensuring the quality of the sheared product and improving the product qualification rate. In addition, since the entire shearing process is a semi-automatic operation, compared with fully automatic operation, it can reduce equipment operating costs while meeting the precision requirements of product material head trimming, making it more suitable for small-scale factories.

[0022] The tooling table 102 is mounted on the support frame 101. The contouring tool 103, the clamping mechanism 104, the four-bar linkage 105, and the shearing mechanism 106 are all mounted on the tooling table 102. The contouring tool 103 matches the shape of the product and is used to load the product. The clamping mechanism 104 is located outside the contouring tool 103 and is used to clamp the product. The four-bar linkage 105 is manually pushed to drive the shearing mechanism 106 to move back and forth. The shearing mechanism 106 is connected to the four-bar linkage 105 and is used to shear the product material. A storage box is also provided on the outside of the support frame 101 to store the products to be sheared. A counter is also provided on the tooling table 102 to count the production quantity so that the staff can understand the production status in real time.

[0023] Secondly, the waste receiving mechanism 107 is located below the tooling table 102 and is used to collect and process the waste obtained from shearing in a unified manner. The waste receiving mechanism 107 is a receiving groove, and a storage box is also provided below the receiving groove. The storage box has an open top and a hollow interior. During the shearing process of the product material head, the waste generated by shearing will enter the storage box from the receiving groove, so that the waste can be collected in a unified manner for subsequent recycling.

[0024] Furthermore, there are two clamping mechanisms 104, which are respectively arranged on the front and rear sides of the contouring fixture 103, so as to clamp the contouring fixture 103 and thereby clamp the product.

[0025] Meanwhile, the shearing mechanism 106 is a shearing blade, and the blade head of the shearing blade is designed to be detachable, so as to quickly replace the blade head of the shearing blade after it is worn.

[0026] Finally, the contouring fixture 103 is designed to be detachable, so as to achieve the purpose of the semi-automatic four-bar linkage shearing fixture to shear the material heads of similar products.

[0027] When using this utility model, during shearing, the product stored in the storage box is taken out and placed into the contour tooling 103. Then, the clamping mechanisms 104 on the front and rear sides are driven to move relative to each other on the tooling table 102, so that the clamping mechanisms 104 can clamp the product. After clamping the product, the four-bar linkage 105 is manually pushed, so that the driving force can be transmitted to the linear guide rail, which in turn can push the shearing mechanism 106 forward. Through the forward movement of the shearing mechanism 106, the product head can be cut off, realizing semi-automatic shearing of the product head. During the shearing process, the sheared head can enter the storage box from the receiving groove, so that the waste can be collected uniformly for subsequent recycling. At the same time, the counter will count the production quantity so that the staff can understand the production status in real time.

[0028] Because the cutting head of the shearing mechanism 106 is detachable, the cutting head of the shearing mechanism 106 can be quickly replaced after it is worn. Because the contouring fixture 103 is detachable, the semi-automatic four-bar linkage cutting fixture can cut the cutting heads of similar products, thereby improving the applicability of the cutting fixture.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
