Description

Technical Field

[0001] This utility model relates to a cutting and processing equipment, and more particularly to a cutting and waste collection equipment suitable for gate processing. Background Technology

[0002] In the production and processing of injection molded parts, castings and other products, the gate is an essential structure in the molding process and needs to be precisely removed in subsequent processes. Therefore, gate cutting equipment has become a key piece of equipment to improve product processing efficiency and quality.

[0003] Several technical solutions for gate cutting have been disclosed, such as the commonly used rotary cutting mechanism for removing gates from injection molded parts. This mechanism uses a rotary cylinder to drive the blade to change the cutting angle, which improves the efficiency of gate removal to some extent. However, this solution does not involve a precise limiting structure during the product cutting process, making it difficult to avoid processing errors caused by product movement during cutting. Furthermore, it does not mention a corresponding waste sorting and collection design, which is not conducive to subsequent waste recycling.

[0004] Meanwhile, existing technology includes a band saw for cutting risers and gating gates in castings. This equipment uses a gear-driven linkage structure to quickly switch between clamping and positioning modes for conventional and irregularly shaped castings, adapting to the cutting needs of castings of different shapes without changing tooling, thus significantly improving the equipment's versatility. However, this solution is mainly designed for cutting risers and gating gates in castings, using a band saw blade cutting method. It has poor compatibility with the blade-type cutting commonly used for injection molded parts, and its clamping mechanism lacks linkage between the drive method and the cutting action, making it impossible to achieve precise control of the clamping force simultaneously during the cutting process. Furthermore, it lacks a classification and collection structure for multiple types of gating gates, leading to mixed waste disposal and increased subsequent processing costs.

[0005] Therefore, while existing processing equipment can automate the cutting process, product positioning is mostly based on a single pre-fixed mode, making it prone to damage due to product movement during cutting. Some equipment has a certain degree of versatility, but adapting to products of different thicknesses and shapes requires complex tooling adjustment processes, and it lacks linkage and limit functions between cutting and clamping. In addition, most equipment uses a single waste collection mode, failing to classify and collect different types of gate waste, thus affecting recycling efficiency.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a cutting and waste collection device suitable for gate processing, so as to make it more industrially valuable. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a cutting and waste collection device suitable for gate processing.

[0008] This utility model discloses a cutting and waste collection device suitable for gate processing, comprising a base, wherein: a waste collection device is installed in the base, a support bracket is installed at the tail end of the base, the support bracket is located above the waste collection device, and a product positioning device is installed on the support bracket; a downward driving device is also installed on the support bracket, and a cutting device is installed on the downward driving device, the cutting device being located above the product positioning device; the product positioning device includes a carrier plate connected to the base, a receiving groove is formed on the carrier plate, guide grooves are mirror-distributed on both sides of the receiving groove, and a clamping mechanism is movably installed in the guide groove; contact guide components are installed at both ends of the cutting device, when the cutting device moves downward, the contact guide components contact the clamping mechanism, causing the clamping mechanism to move along the guide groove towards the receiving groove and contact the product body, thereby limiting the product's position.

[0009] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, the receiving trough includes a vertical main trough, with extension troughs distributed at both the upper and lower ends of the vertical main trough; the vertical main trough also has material pick-up clearance openings distributed on it.

[0010] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, a replaceable pad is installed in the guide groove.

[0011] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, the clamping mechanism includes a guide shaft horizontally installed in a guide groove, a clamping block movably sleeved on the guide shaft, a contact baffle installed at one end of the clamping block facing the collection groove, and a contact ramp distributed on one side of the clamping block corresponding to the contact guide assembly.

[0012] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, a return spring is fitted at one end of the guide shaft near the receiving groove.

[0013] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, a top limiting frame is installed on the contact baffle.

[0014] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, the cutting device includes a tool holder on which a trapezoidal blade is mounted, and contact guide components are mounted at both ends of the tool holder; the tool holder is connected to the pressing drive device via limit bolts; the trapezoidal blade has elongated adjustment holes distributed on it, and positioning screws are installed in the elongated adjustment holes and connected to the tool holder; a processing groove is formed at the cutting edge of the trapezoidal blade; the pressing drive device is a pneumatic cylinder or an electric cylinder.

[0015] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, the contact guide component is a guide roller, and contact rings are distributed around the guide roller.

[0016] Furthermore, in the aforementioned cutting and waste collection equipment applicable to gate processing, the waste collection device includes a waste box installed in the equipment base, a box cover installed on the waste box, an inlet on the box cover, and the inlet corresponding to the collection slot; the box cover is connected to the waste box by a pin.

[0017] Furthermore, in the aforementioned cutting and waste collection equipment suitable for gate processing, a connecting bracket is installed on one side of the equipment base.

[0018] By means of the above solution, this utility model has at least the following advantages: 1. It integrates product positioning, gate cutting, and waste collection functions into the overall structure formed by the equipment base and support frame. Compared with traditional decentralized gate processing equipment, there is no need to build an additional transfer structure between multiple devices, which not only reduces the space occupied by the equipment, but also avoids the time loss and collision risk of product transfer between multiple processes, significantly improving the overall continuity and production efficiency of gate processing.

[0019] 2. A clamping mechanism using a guide shaft and linear bearings, combined with the upper and lower limiting action of the top limiting frame, allows for precise omnidirectional and vertical limiting of the product before cutting, effectively preventing product movement during cutting. Furthermore, the machining grooves on the trapezoidal blade edge avoid the product body, and the blade spacing can be precisely adjusted via the elongated adjustment hole and limiting bolts, ensuring that only the gate is cut without damaging the product itself. This significantly reduces the product defect rate and improves the precision of gate cutting.

[0020] 3. To meet the gate processing requirements of different product models, this utility model achieves adaptation through an adjustable and replaceable structure, eliminating the need to customize special equipment for each product. This significantly reduces equipment investment costs in multi-variety, small-batch production scenarios and improves the equipment's versatility and cost-effectiveness.

[0021] 4. The clamping block automatically resets after cutting via a return spring. The material handling opening on the carrier plate facilitates product loading and unloading. The equipment startup and operation process is simple and controllable. The waste box is connected to the lid with pins, allowing for quick disassembly and cleaning. Replaceable pads, carrier plates, and other components all use detachable connections, eliminating the need for complex tools for later replacement and maintenance. The overall design significantly reduces the learning curve for operators and the workload of daily maintenance, minimizing equipment downtime and ensuring continuous and stable production.

[0022] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the overall structure of a cutting and waste collection device suitable for gate processing.

[0024] Figure 2 This is a schematic diagram of the installation structure of the waste collection device.

[0025] The meanings of the labels in the figures are as follows.

[0026] Detailed Implementation The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] like Figures 1 to 2 This cutting and waste collection equipment, suitable for gate processing, includes a base 1 made of high-strength aluminum alloy and anodized to improve surface wear resistance and corrosion resistance. The base 1 has mounting holes at its bottom for bolt fixation to the worktable, preventing displacement during operation. Its unique feature is the inclusion of a waste collection device within the base 1. Specifically, the waste collection device includes a waste box 15 recessed within the base 1. The waste box 15 is a rectangular box with an open top, made of PP material for lightweight and easy cleaning. A cover 16 is mounted on the waste box 15, a flat structure adapted to the top of the waste box 15, with an inlet 17. The inlet 17 corresponds to the receiving slot of the product positioning device, ensuring that the cut waste accurately falls into the corresponding waste box 15. Meanwhile, the lid 16 is connected to the waste box 15 by a pin. When the waste material in the waste box 15 accumulates to a certain amount, the pin can be pulled out and the waste box 15 can be manually removed for cleaning, which is convenient.

[0028] According to a preferred embodiment of this utility model, a support bracket 2 is installed at the tail end of the equipment base 1. This support bracket is welded from steel plates and detachably connected to the equipment base 1 via bolts, facilitating future maintenance. A product positioning device is installed on the crossbeam of the support bracket 2. Specifically, the product positioning device includes a carrier plate 3 connected to the equipment base 1, which is connected to the support bracket 2 via positioning pins. A storage groove is provided on the carrier plate 3, the shape of which matches the contour of the product body 19 to be processed, for initial placement of the product. During implementation, the storage groove includes a vertical main groove extending along the length of the carrier plate 3 to accommodate the length of the product. Extension grooves are distributed at both the upper and lower ends of the vertical main groove, communicating with it, and their length can be adapted to the lateral extension mechanism of the product. Simultaneously, a material removal clearance opening 4 is also distributed on the vertical main groove, located at the front end of the carrier plate 3, facilitating manual removal of the product after cutting and avoiding interference between the hand or robotic arm and the edge of the carrier plate 3.

[0029] Furthermore, on both sides of the carrier plate 3 located in the storage groove, guide grooves are mirror-distributed, and a clamping mechanism is movably installed within the guide grooves. The clamping mechanism used in this invention includes a guide shaft 6 horizontally installed in the guide groove. The guide shaft 6 is made of stainless steel and its surface is polished to reduce sliding friction resistance. A clamping block 7 is movably sleeved on the guide shaft 6. A linear bearing is installed inside the clamping block 7 and it is sleeved on the guide shaft 6 to ensure that the clamping block 7 moves precisely left and right along the guide shaft 6. At the same time, a contact baffle is installed at the end of the clamping block 7 facing the storage groove, and the inner side of the contact baffle contacts the product body 19. In addition, a contact ramp 8 is distributed on the side of the clamping block 7 corresponding to the contact guide component. The inclination angle of the contact ramp 8 is 30° to 45°, which facilitates smooth contact and push of the clamping block 7 when the contact guide component moves down. During manufacturing, the side of the clamping block 7 located on the contact ramp 8 is made of Teflon material. This material has a low coefficient of friction and high wear resistance, which can reduce frictional wear with the contact guide component and avoid scratching the product surface. To facilitate easy resetting during use, a reset spring is fitted at one end of the guide shaft 6 near the storage groove. One end of the reset spring abuts against the limiting protrusion of the guide shaft 6, and the other end abuts against the side wall of the clamping block 7. Thus, when the cutting device moves upward, the elastic restoring force of the reset spring can push the clamping block 7 back along the guide shaft 6, facilitating the next product placement. Furthermore, a top limiting frame 9 is installed on the contact baffle. The top limiting frame 9 has a U-shaped structure, and its height is adapted to the thickness of the product's extended side wings, ensuring that the product has no vertical displacement space after clamping. For some similar products with thickness differences, replaceable pads 5 can be installed in the guide groove. The replaceable pads 5 are rectangular blocks made of rubber to provide a certain degree of elasticity. Different height replaceable pads 5 can be replaced according to the thickness of the product to be processed, ensuring the clamping stability of the clamping mechanism for products of different thicknesses. They are detachably connected to the extension groove via a snap-fit ​​structure for easy and quick replacement.

[0030] In practical implementation, a downward driving device, either a pneumatic cylinder or an electric cylinder, is also installed on the crossbeam of the support bracket 2. In this embodiment, a standard pneumatic cylinder is selected. The cylinder diameter is chosen based on the required cutting pressure, and the stroke is set according to the product height and cutting depth. The cylinder's air inlet is connected to the air source via a solenoid valve for automated control. A cutting device is installed at the piston rod end of the downward driving device, located above the product positioning device, and is used to cut the product's gate.

[0031] Furthermore, the cutting device includes a tool holder 10, which can be made of high-strength steel to ensure no deformation during cutting. Trapezoidal blades 11 are mounted on the tool holder 10. The tool holder 10 is connected to the downward drive device via a limiting bolt. The limiting bolt passes through a slotted hole in the tool holder 10 and connects to the piston rod of the downward drive device, allowing for fine-tuning of the horizontal position of the tool holder 10 to ensure the trapezoidal blades 11 are aligned with the gate. Additionally, the trapezoidal blades 11 have elongated adjustment holes 12, each containing a positioning screw connected to the tool holder 10. Loosening the positioning screw allows adjustment of the position of the trapezoidal blades 11 along the length of the elongated adjustment holes 12, thereby adjusting the spacing between the two trapezoidal blades 11 to accommodate different products. A machining groove 13 is formed at the cutting edge of the trapezoidal blades 11. The shape of the machining groove 13 matches the protruding structure of the product body, ensuring that the trapezoidal blades 11 only act on the gate during cutting without damaging the product body. Furthermore, the size of the trapezoidal blade 11 can be customized according to the distribution and shape requirements of the gate. For different processing needs, two trapezoidal blades 11 can be used on the front and rear sides of the tool holder 10 to adapt to the gate processing distribution.

[0032] To effectively guide the force applied to the clamping block 7, contact guide components are installed at both ends of the tool holder 10. Specifically, the contact guide components are guide rollers 14, which are rotatable roller mechanisms. The guide rollers 14 are rotatably connected to the tool holder 10 via axles. Contact rings are distributed around the guide rollers 14. These contact rings are made of polyurethane to provide a certain degree of elasticity, preventing hard contact with the contact ramp 8 of the clamping block 7 that could lead to wear. Alternatively, the contact rings could be made of Teflon.

[0033] Meanwhile, in order to meet the needs of docking and installation with other processing equipment, a connecting bracket 18 can be installed on one side of the equipment base 1. The connecting bracket 18 is an "L" shaped plate structure, and its height can be adjusted by adjusting bolts. It can be docked with external conveyor lines, which facilitates the transfer of products after cutting to the next process and improves production efficiency.

[0034] The working principle of this utility model is as follows: By using a feeding robot or manually, the product body 19 that needs to be gated is embedded into the storage slot of the carrier plate 3, ensuring that the extended side wings of the product body 19 are located below the top limiting frame 9, thus initially achieving the pre-positioning of the product.

[0035] Afterwards, the equipment starts, and the piston rod of the downward drive device extends, driving the entire cutting device downward. During the downward movement of the cutting device, the guide rollers 14 at both ends first contact the contact ramp 8 of the clamping block 7 of the clamping mechanism. As the cutting device continues to move downward, the guide rollers 14 generate a horizontal component force on the contact ramp 8, pushing the clamping block 7 to move along the guide shaft 6 in the guide groove towards the receiving groove until the contact baffle contacts the product body 19. At the same time, the top limiting frame 9 locks the extended side wings of the product, achieving all-round limiting of the product in both sides and vertical directions, ensuring that the product will not move during cutting.

[0036] Next, the cutting device continues to move downwards, and the trapezoidal blade 11 on the tool holder 10 contacts the gate of the product. The machining groove 13 on the cutting edge of the trapezoidal blade 11 avoids the non-cutting position of the product body and only cuts the gate. In order to optimize the cutting process of the gate, a design of two trapezoidal blades 11 can be adopted. The distance between the two blades is preset according to the position of the product gate, and the cutting of both gates can be completed in one go.

[0037] The cut waste material falls into the corresponding waste box 15 through the feed port 17 on the box cover 16. When the waste box 15 needs to be cleaned, it can be manually removed by pulling out the pin. After the gate cutting is completed, the piston rod of the downward drive device retracts, driving the cutting device to move upward. During the upward movement of the cutting device, the guide pressure roller 14 disengages from the contact ramp 8 of the clamping block 7, and the clamping block 7 resets along the guide shaft 6 under the elastic restoring force of the return spring. Finally, the cut product is manually removed through the material removal clearance port 4 of the carrier plate 3, completing one processing cycle.

[0038] During use, when gate cutting is required for different product models, it can be achieved through a change-of-type fixture. Specific operations include: removing the fixing bolts between the carrier plate 3 and the support bracket 2, removing the original carrier plate 3 (i.e., the original product positioning fixture), replacing it with a carrier plate 3 compatible with the new product, and repositioning and fixing it using positioning pins. Depending on the thickness of the new product, replace the replaceable pad 5 in the extension groove to ensure the clamping height of the clamping mechanism is appropriate. The spacing between the two trapezoidal blades 11 can be adjusted along the elongated adjustment hole 12 by loosening the positioning screws of the trapezoidal blade 11 to match the gate position of the new product. After adjustment, tighten the positioning screws. If the gate type or quantity of the new product changes, the number of waste boxes 15 can be replaced accordingly or the position of the inlet 17 can be adjusted to ensure accurate waste collection.

They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
