Description

Technical Field

[0001] This utility model relates to the field of plastic mold cutting technology, and more specifically, to a model cutting device for plastic mold processing and production. Background Technology

[0002] Plastic molds are tools used to mold plastic products. With the help of molding processes such as injection molding, blow molding, and extrusion, various plastic products such as mobile phone cases, plastic bottles, and toys can be shaped.

[0003] The model cutting device used in plastic mold processing and production is a key piece of equipment in the plastic mold manufacturing process. In the mold model processing stage, the raw materials of the mold model are cut according to the design requirements through various cutting methods such as stamping, laser, and mechanical cutting to shape key parts such as cavity, core, and parting surface, laying the foundation for creating high-precision and high-quality plastic molds.

[0004] However, in the field of plastic mold processing, existing plastic mold processing and cutting equipment usually uses a variety of cutting methods such as stamping, laser, and mechanical cutting. Among them, stamping cutting has a significant advantage in model processing efficiency compared with laser cutting and mechanical tool rotary cutting due to its high efficiency. It can complete the cutting of a large number of models in a short time. However, in actual application scenarios, the stamping cutting method has exposed many drawbacks. On the one hand, its flexibility is poor. The installation and disassembly of the clamping mold and stamping cutting tool require the staff to use professional tools and follow a cumbersome process. For example, when changing stamping tools of different specifications and positioning clamping molds, not only must specific wrenches, screwdrivers and other tools be used to unscrew multiple fastening screws, but the tool position must also be carefully adjusted to ensure installation accuracy. The whole process is time-consuming and labor-intensive. This complicated operation not only increases the labor intensity of the staff and prolongs the downtime of the equipment, but also reduces production efficiency.

[0005] On the other hand, with existing stamping and cutting equipment, workers need to manually clean the cutting table every time a model is cut to remove the plastic debris generated during cutting. Frequent manual cleaning of these debris not only consumes a lot of time and energy, but also easily leads to product quality problems due to incomplete cleaning, causing many inconveniences to actual production and restricting the continuity and efficiency of the production process.

[0006] In view of this, we propose a model cutting device for plastic mold processing and production. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of this invention is to provide a model cutting device for plastic mold processing and production, so as to solve the problems mentioned in the background art.

[0009] 2. Technical Solution

[0010] A mold cutting device for plastic mold processing and production includes a cutting table, a controller installed on the outer wall of the front of the cutting table, a groove on the top of the cutting table, a support column fixedly connected to the bottom of the inner cavity of the groove, a mold clamping device engaged on the top of the support column, an installation groove on the top of the cutting table, an electric push rod fixedly connected inside the installation groove, a support rod connected to the output end of the electric push rod, a connecting rod fixedly connected to the bottom of the support rod, a lifting plate connected to the end of the connecting rod, a fixed seat fixedly connected to the top of the cutting table, a connecting plate connected to the outer wall of the fixed seat, a cylinder installed on the top of the connecting plate, a second clamping block connected to the output end of the cylinder, and an installation seat clamping device engaged on the outer wall of the second clamping block.

[0011] Preferably, the top of the support column is provided with a snap-fit ​​groove, and the inner wall of the snap-fit ​​groove is provided with a limiting hole.

[0012] Preferably, a snap-fit ​​block is fixedly connected to the bottom of the snap-fit ​​mold, and the snap-fit ​​block matches the snap-fit ​​groove.

[0013] Preferably, a spring is fixedly connected to the inner wall of the inner cavity of the snap-fit ​​block, and a limiting block matching the limiting hole is connected to the end of the spring.

[0014] Preferably, the lifting plate is matched with the groove, and the top of the lifting plate has a through-hole that matches the support column.

[0015] Preferably, the second snap-fit ​​block has the same structure as the first snap-fit ​​block, and the top of the mounting base has a snap-fit ​​groove of the same shape.

[0016] Preferably, a connecting rod is fixedly connected to the outer circumference of the mounting base, and a stamping and cutting tool is connected to the end of a plurality of the connecting rods.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this utility model are as follows: In actual use, the appropriate snap-fit ​​mold and stamping cutting tool can be selected according to the shape and size of the plastic model. When the snap-fit ​​mold needs to be installed, the limiting block can be pressed first, so that the limiting block retracts by the action of the spring. Then, the snap-fit ​​block one can be snapped into the snap-fit ​​groove on the top of the support column. When it is snapped to the limit position, the limiting block will spring back into the limiting hole by the action of the spring. The stamping cutting tool uses the same method to snap the snap-fit ​​block two into the cylinder output end, which facilitates the stamping and cutting of plastic models of various sizes and shapes. When the snap-fit ​​mold and stamping cutting tool need to be replaced, the respective limiting blocks can be pressed, and then they can be pulled out and disassembled. The overall use is simpler and more convenient, improving its overall practicality and flexibility.

[0019] Furthermore, the debris generated from stamping and cutting falls directly into the groove inside the cutting table. When the debris accumulates to a certain level and needs to be collected, the operator can activate the electric push rod to raise the lifting plate smoothly. As the lifting plate rises, the debris piled on top also rises, making it convenient for the operator to collect and process the debris uniformly. It is worth mentioning that the groove has a certain depth, which can hold a lot of debris and can continuously collect the debris generated from stamping and cutting for a certain period of time. This reduces the workload of operators in frequently cleaning debris and makes subsequent cleaning more convenient, ensuring the continuity of the production process and improving production efficiency.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] A model cutting device for processing and producing plastic molds includes a cutting table 100, a controller 110 is provided on the outer wall in front of the cutting table 100, a groove 120 is opened on the top of the cutting table 100, a support column 130 is fixedly connected to the bottom of the inner cavity of the groove 120, and a mold 140 is snapped into the top of the support column 130.

[0031] In some embodiments, the snap-fit ​​mold 140 can be changed according to the size and shape of the plastic mold, thereby facilitating the positioning and snap-fit ​​of the plastic mold.

[0032] The top of the cutting table 100 is also provided with a mounting groove, and an electric push rod 200 is fixedly connected inside the mounting groove. The output end of the electric push rod 200 is connected to a support rod 210. The bottom of the support rod 210 is fixedly connected to a connecting rod 220. The end of the connecting rod 220 is connected to a lifting plate 230. The top of the cutting table 100 is also fixedly connected to a fixed seat 300. The outer wall of the fixed seat 300 is connected to a connecting plate 310. A cylinder 320 is set on the top of the connecting plate 310. The output end of the cylinder 320 is connected to a second snap-fit ​​block 321. The outer wall of the second snap-fit ​​block 321 is snap-fitted to a mounting seat 330.

[0033] In some embodiments: the electric linear actuator 200 is existing technology and can be a common model available on the market. Its internal structure mainly includes a motor, a lead screw, a nut, a push rod, and a control circuit. The motor drives the lead screw to rotate, and the nut that cooperates with the lead screw moves linearly along the axis of the lead screw under the drive of the lead screw, thereby driving the push rod connected to the nut to achieve linear extension and retraction. By controlling the forward and reverse rotation and speed of the motor through the control circuit, the extension or retraction length and running speed of the push rod can be precisely controlled to meet the needs of various scenarios that require linear power output.

[0034] In some embodiments, the cylinder 320 mainly consists of a cylinder barrel, piston, piston rod, front and rear end caps, and seals. When compressed air enters from the air inlet at one end of the cylinder barrel, a pressure difference is formed on the piston side, pushing the piston to move axially within the cylinder barrel. The piston rod then extends or retracts. Based on this principle, the cutting equipment accurately transmits the reciprocating linear motion of the cylinder to the cutting tool to achieve the stamping and cutting action of the plastic model. At the same time, by adjusting the air inlet pressure and flow rate and using a control valve, the cylinder's movement speed, output force, and action sequence can be flexibly controlled to meet different cutting requirements. All of the above belong to the prior art.

[0035] Specifically, the top of the support column 130 is provided with a snap-fit ​​groove 131, and the inner wall of the snap-fit ​​groove 131 is provided with a limit hole 132 to facilitate snap-fitting of the snap-fit ​​mold 140.

[0036] Furthermore, a snap-fit ​​block 141 is fixedly connected to the bottom of the snap-fit ​​mold 140. The snap-fit ​​block 141 matches the snap-fit ​​groove 131, which facilitates snapping the snap-fit ​​mold 140 onto the top of the support column 130.

[0037] Furthermore, a spring 142 is fixedly connected to the inner wall of the snap-fit ​​block 141, and a limiting block 143 matching the limiting hole 132 is connected to the end of the spring 142 to facilitate limiting after snap-fit.

[0038] Furthermore, the lifting plate 230 is matched with the trough 120, and the top of the lifting plate 230 is provided with a through-hole 240 that matches the support column 130, which facilitates the collection of plastic waste.

[0039] It is worth noting that the second snap-fit ​​block 321 has the same structure as the first snap-fit ​​block 141, and the mounting base 330 has a snap-fit ​​groove 131 of the same shape on the top, which facilitates the snap-fit ​​installation of the stamping and cutting tool 340.

[0040] It is worth noting that the mounting base 330 is fixedly connected to the outer circumference of the mounting base 330, and the ends of multiple connecting rods are connected to stamping and cutting tools 340, which facilitates the use of stamping and cutting tools 340 to stamp and cut the excess waste material on the outer wall of the plastic model.

[0041] In some embodiments, the device can be powered by an external power source, and the device can be controlled by the controller 110.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Working Principle: In actual use, the appropriate snap-fit ​​mold 140 and stamping cutting tool 340 can be selected according to the shape and size of the plastic model. When the snap-fit ​​mold 140 needs to be installed, the limiting block 143 can be pressed first, causing the limiting block 143 to retract under the action of the spring 142. Then, the snap-fit ​​block 141 can be snapped into the snap-fit ​​groove 131 on the top of the support column 130. When snapped to the limit position, the limiting block 143 will spring back into the limiting hole 132 under the action of the spring 142 for limiting. The stamping cutting tool 340 uses the same method to snap-fit ​​block 321 into the output end of the cylinder 320, which facilitates the stamping and cutting of plastic models of various sizes and shapes. When it is necessary to change the snap-fit ​​mold 140 and the stamping cutting tool 340, the respective limiting blocks 140 can be pressed. 43. After that, it can be pulled out and disassembled, making the overall use simpler and more convenient, improving its overall practicality and flexibility. In addition, the debris generated by stamping and cutting will fall directly into the groove 120 inside the cutting table 100. When the debris inside the groove 120 accumulates to a certain level and needs to be collected, the operator can start the electric push rod 200 to drive the lifting plate 230 to rise smoothly. As the lifting plate 230 rises, the debris accumulated on top of it also rises, making it convenient for the operator to collect and process the debris uniformly. It is worth mentioning that the groove has a certain depth and can hold a lot of debris, which can continuously collect the debris generated by stamping and cutting for a certain period of time, reducing the workload of the operator to clean the debris frequently, and making the later cleaning more convenient, ensuring the continuity of the production process and improving production efficiency.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
