Description

Technical Field

[0001] This utility model relates to the field of sprue shearing equipment technology, and in particular to a sprue shearing structure. Background Technology

[0002] Most plastic products produced by plastic molds have sprues, which need to be removed later. The quality of sprue removal not only affects the product's appearance and dimensional accuracy, but also the efficiency of subsequent processing, so this step is very important.

[0003] However, when faced with large and irregular sprue gates, traditional sprue cutters, due to their own structural and performance limitations, exhibit slow gate cutting speed during the cutting process, reducing production efficiency. The cut product surface often has burrs, affecting the product's appearance quality and increasing subsequent processing steps and costs. Furthermore, for some sprue gates in complex locations, due to limited operating space, traditional sprues simply cannot achieve effective cutting, making it difficult to meet production needs.

[0004] Prior art 1 (Chinese patent application number CN202323287541.0, application date 2023-12-04) discloses a portable electric sprue cutter. The cutter head includes two blades connected by a pin shaft. The pin shaft is installed at one end of the anti-rotation cylinder. The tail ends of the two blades are inserted into the anti-rotation cylinder. One end of the limiting piston forms a clamping cavity and is inserted into the anti-rotation cylinder. The clamping cavity engages and closes the tail ends of the two blades. The other end of the limiting piston is fixedly connected to the connecting sleeve. The connecting sleeve is threaded to the lead screw, converting the rotary motion of the motor into the linear motion of the piston. The optimized mechanical design minimizes force loss.

[0005] Prior art 2 (Chinese patent application number CN201822189709.7, application date 2018-12-25) discloses a sprue cutting device for injection molded products. The injection molded product includes a first sprue and a second sprue symmetrically arranged along the Z-axis. The device includes a fixed bracket and a cutting mechanism mounted on the fixed bracket. The fixed bracket is vertically provided with a clamping assembly for fixing the injection molded product. The cutting mechanism includes pneumatic shears, which are arranged corresponding to the first sprue. The cutting mechanism also includes a rotary cylinder connected to the pneumatic shears and drives the pneumatic shears to rotate 180° along the X-axis to correspond with the second sprue. This device can cut the first and second sprues symmetrically arranged on the injection molded product. After cutting the first sprue, the pneumatic shears are rotated to cut the second sprue. No manual cutting is required, which improves production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a sprue shearing structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: it includes a base, a cylinder is provided at the bottom of the base, a fixed blade holder is provided on one side of the base, a shearing assembly is provided on the fixed blade holder, and a heating assembly is provided on one side of the shearing assembly.

[0008] As a preferred embodiment of the present invention, the shearing assembly includes a mounting base one disposed on the inner top surface of the fixed blade holder, a fixed blade one disposed at the bottom of the mounting base one, the output end of the cylinder penetrating the base, a mounting base two disposed at the output end of the cylinder, and a movable blade one disposed on the mounting base two.

[0009] As a preferred embodiment of the present invention, the heating assembly includes a fixed blade heating rod disposed on one side of the fixed blade, and a movable blade heating rod disposed on one side of the movable blade.

[0010] As a preferred embodiment of this invention, a pair of speed control valves are provided on one side of the cylinder.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. This utility model, by setting up a shearing assembly, provides a stable mounting base for the fixed blade, ensuring that the fixed blade is fixed in position and stable in state during the shearing process. The mounting base at the cylinder output end can drive the movable blade to perform linear reciprocating motion, so that the movable blade and the fixed blade cooperate to realize the opening and closing action. This makes the shearing process powerful and smooth, and can quickly and effectively shear the sprue. Secondly, the cooperation between the movable blade and the fixed blade concentrates the shearing force, which can handle sprue materials of different hardness and thickness, greatly improving the shearing efficiency and quality, and reducing the secondary processing caused by incomplete shearing.

[0013] 2. This utility model improves the contact state between the blade and the material by setting up a heating component. The heating rods for the fixed blade and the moving blade heat the fixed blade and the moving blade respectively. During the shearing process, the heated blade can better soften the material surface and reduce the hardness of the material, making it easier for the blade to cut into the material. This reduces the force required for shearing and lowers the energy consumption of the equipment. At the same time, the friction between the heated blade and the material is reduced, making the shearing process smoother. It can effectively avoid problems such as uneven shearing and burrs caused by the blade sticking to the material, improve the flatness and smoothness of the sheared surface, and ensure the shearing quality.

[0014] 3. By setting a fixed blade holder, this utility model addresses the issue that during the shearing operation, the product often needs to be placed near the blade holder. Traditional straight blade holders are prone to colliding with the product, causing damage. However, the curved structure of the fixed blade holder cleverly avoids the product, leaving enough space for it and ensuring that the product remains in a safe area during the shearing process. This effectively prevents product damage caused by collisions and improves the product yield. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figures 1-4 As shown, the present invention proposes a sprue shearing structure, which includes a base 1, which provides an installation foundation for other components in the overall device. A cylinder 2 is provided at the bottom of the base 1, which provides a power source. Its output end can perform linear reciprocating motion, which drives the movable blade 44 to move by driving the mounting base 43, thereby realizing the opening and closing action with the fixed blade 42 and completing the shearing operation. A fixed blade holder 3 is provided on one side of the base 1. The fixed blade holder 3 has a tortuous structure, which can effectively avoid the product during the shearing process, prevent the product from colliding with the fixed blade holder 3, and avoid damage to the product. A shearing component 4 is provided on the fixed blade holder 3, and a heating component 5 is provided on one side of the shearing component 4.

[0022] The shearing assembly 4 includes a mounting base 41 disposed on the inner top surface of the fixed blade holder 3. The mounting base 41 provides a mounting foundation for the fixed blade 42. The fixed blade 42 is disposed at the bottom of the mounting base 41. The fixed blade 42 cooperates with the movable blade 44. When the cylinder 2 drives the movable blade 44 to move, it shears the sprue. The output end of the cylinder 2 passes through the base 1. The output end of the cylinder 2 is provided with a mounting base 43. The mounting base 43 provides a mounting foundation for the movable blade 44. The movable blade 44 is disposed on the mounting base 43. Under the drive of the cylinder 2, the movable blade 44 moves closer to or further away from the fixed blade 42 to achieve shearing of the sprue.

[0023] The heating assembly 5 includes a fixed blade heating rod 51 disposed on one side of the fixed blade 42. The fixed blade heating rod 51 heats the fixed blade 42, allowing the fixed blade 42 to better contact the material during shearing and improving the shearing effect. A movable blade heating rod 52 is disposed on one side of the movable blade 44. The movable blade heating rod 52 heats the movable blade 44, allowing the movable blade 44 to better contact the material during shearing and improving the shearing effect.

[0024] A pair of speed control valves 6 are provided on one side of cylinder 2. The operator can control the running speed of cylinder 2 by adjusting the speed control valves 6 to adapt to the shearing requirements of different materials and ensure shearing quality and efficiency.

[0025] During use, the operator first adjusts the entire device to the correct position. The tortuous structure of the fixed blade holder 3 effectively avoids the product, preventing damage during the shearing process. Simultaneously, a speed control valve 6 is located on one side of the cylinder 2, allowing the operator to adjust the cylinder 2's operating speed according to different shearing requirements. After adjustment, the operator activates the fixed blade heating rod 51 and the movable blade heating rod 52 to heat the fixed blade 42 and the movable blade 44. The heated blades 42 and 44 can better contact the material, preparing for successful sprue removal. Next, the operator activates the cylinder 2, whose output drives the mounting base 43 upwards. The movable blade 44 on the mounting base 43 rises accordingly, cooperating with the fixed blade 42 to complete the sprue shearing operation. This not only ensures the shearing effect but also further reduces accidental damage to the product.

[0026] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
