Description

Technical Field

[0001] The utility model belongs to the technical field of mold processing and relates to a PVC mold clamping machine. Background Art

[0002] The mold clamping machine is a professional mold research and fitting equipment, which is mainly used to pressurize and close the upper and lower molds with the required pressure during the later research and fitting of mold production.

[0003] The existing mold clamping machine case is fixed with a mounting plate, and two pressurized cylinders are fixed on the top of the mounting plate. The telescopic rods of the two pressurized cylinders pass through the mounting plate and are fixed with an upper die. When the cylinder pushes the upper die downward through the telescopic rod, the upper die cooperates with the lower die to process the material. At this time, the upper die and the lower die are butted against each other, and an upward tension is generated in the process of pressing the material. The tension is transmitted to the cylinder in turn through the upper die, the telescopic rod, and the mounting plate, causing the cylinder to vibrate. In addition, the existing technology only provides one mounting plate for fixing the cylinder, which leads to poor stability of the cylinder during processing, and thus poor processing quality. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the existing technology and to propose a PVC mold clamping machine for solving the technical problem of poor stability of the cylinder in the molding process in the existing technology mentioned in the background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A PVC mold clamping machine includes a working frame and a box body, the box body is fixed on the top of the working frame, and a mounting plate is fixed to the bottom of the box body through a connecting block. Two pressurized cylinders arranged in parallel are fixed to the top of the mounting plate. Two openings are opened at the bottom of the box body for the two pressurized cylinders to pass through respectively. From left to right, the telescopic ends of the two pressurized cylinders pass through the mounting plate and are respectively fixed with a heating mold and a cooling mold located at the lower end of the mounting plate. A support plate is fixed in the working frame, two pull rods 1 are fixed between the support plate and the connecting block, four pull rods 2 distributed in a rectangular shape are fixed between the support plate and the mounting plate, and two lower pressing dies corresponding to the heating mold and the cooling mold are fixed on the top of the support plate.

[0007] Working principle:

[0008] When the two cylinders are driven to respectively drive the heating mold and the cooling mold to descend and make the heating mold and the cooling mold respectively rest against the corresponding two lower pressing dies, an upward tension will be generated in the process of pressing the material, and will be transmitted to the pressurizing cylinder in turn through the heating mold or the cooling mold, the telescopic rod, and the mounting plate. At this time, under the action of the two tie rods one and the four tie rods two, the two tie rods one and the four tie rods two generate a force opposite to the tension, avoiding vibration of the pressurizing cylinder during the pressurization process, thereby ensuring the stability of the pressurizing cylinder during the pressurization process.

[0009] The beneficial effects of the utility model are:

[0010] The utility model cooperates with the arrangement of a mounting plate, a support plate, two tie rods one and four tie rods two. During the pressurization process of the pressurized cylinder, under the action of the two tie rods one and four tie rods two, the two tie rods one and four tie rods two generate a force opposite to the tension, thereby preventing the mounting plate from vibrating during the pressurization process of the pressurized cylinder, thereby ensuring the stability of the pressurized cylinder during the pressurization process.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1-4 As shown, a PVC mold clamping machine includes a working frame 1 and a box body 2, the box body 2 is fixed on the top of the working frame 1, and a mounting plate 4 is fixed to the bottom of the box body 2 through a connecting block 3. Two pressurizing cylinders 5 arranged in parallel are fixed to the top of the mounting plate 4. Two openings 6 are opened at the bottom of the box body 2 for the two pressurizing cylinders 5 to pass through respectively. From left to right, the telescopic ends of the two pressurizing cylinders 5 pass through the mounting plate 4 and are respectively fixed with a heating mold 7 and a cooling mold 8 located at the lower end of the mounting plate 4. A support plate 9 is fixed in the working frame 1, two pull rods 10 are fixed between the support plate 9 and the connecting block 3, four pull rods 11 distributed in a rectangular shape are fixed between the support plate 9 and the mounting plate 4, and two lower pressing molds 12 corresponding to the heating mold 7 and the cooling mold 8 are fixed on the top of the support plate 9. When the two cylinders are driven to respectively drive the heating mold 7 and the cooling mold 8 to descend and make the heating mold 7 and the cooling mold 8 respectively abut against the corresponding two lower pressing molds 12, an upward tension will be generated in the process of pressing the materials, and will be transmitted to the pressurizing cylinder 5 in turn through the heating mold 7 or the cooling mold 8, the telescopic rod, and the mounting plate 4. At this time, under the action of the two tie rods 10 and the four tie rods 2 11, the two tie rods 10 and the four tie rods 2 11 generate a force opposite to the tension, and ensure the stability of the pressurizing cylinder 5 during the pressurization process.

[0020] like Figure 2-5 As shown, a rodless cylinder 13 is fixed on the top of the support plate 9 and is located on the rear side of the lower die 12 at the lower end of the heating mold 7 and is arranged horizontally. A rodless cylinder refers to a cylinder that uses a piston to directly or indirectly connect to an external actuator and makes it follow the piston to achieve reciprocating motion. The biggest advantage of this type of cylinder is that it saves installation space. A push rod 14 is fixed on one end of the driver of the rodless cylinder 13 to drive the rodless cylinder 13. The rodless cylinder 13 can push the material located below the heating mold 7 to the lower die 12 below the cooling mold 8 through the push rod 14. A rodless cylinder 2 15 is fixed on the top of the support plate 9 and is located on the right side of the lower die 12 at the lower end of the cooling mold 8 and is arranged longitudinally. A push rod 2 16 is fixed on one end of the driver of the rodless cylinder 2 15 to drive the rodless cylinder 2 15. The rodless cylinder 2 15 can push the material located below the cooling mold 8 out of the working frame 1 through the push rod 2 16.

[0021] like Figure 2 、 Figure 4 and Figure 6As shown, the upper ends of the heating mold 7 and the cooling mold 8 are fixed with two symmetrically arranged guide rods 17, and the lower end of the mounting plate 4 is fixed with four sleeves 18 corresponding to the four guide rods 17, and the four guide rods 17 pass through the corresponding sleeves 18 respectively. The mounting plate 4 has four guide holes 19 respectively connected to the four corresponding sleeves 18, and the four guide rods 17 pass through the four corresponding guide holes 19 respectively. The upper ends of the guide rods 17 pass through the opening 6 and are located in the box body 2. With the cooperation of the guide rods 17, the sleeves 18 and the guide holes 19, the heating mold 7 and the cooling mold 8 are more stable during the descent or ascent process, and the heating mold 7 and the cooling mold 8 are further prevented from offsetting during the movement.

[0022] like Figure 1 and Figure 5 As shown, an operating platform 20 located at the front end of the two lower pressing dies 12 is fixed at the front end of the working frame 1, and one end of the operating platform 20 has an inclined portion 21 located at the front end of the cooling mold 8. A touch screen 22 is screwed to the middle position of the front of the box body 2, and an electrical status indicator light 23 is embedded in the left side of the front of the box body 2. A number of heat dissipation holes 24 are opened on one side of the box body 2.

[0023] The specific operation mode of the utility model is as follows:

[0024] The material to be processed is placed on the lower die 12 at the lower end of the heating mold 7, and the pressurizing cylinder 5 corresponding to the heating mold 7 is driven. The pressurizing cylinder 5 drives the heating mold 7 to descend, and the heating mold 7 cooperates with the lower die 12 to process the material. In the process of pressing the material, an upward tension is generated and is transmitted to the pressurizing cylinder 5 in turn through the heating mold 7 or the cooling mold 8, the telescopic rod, and the mounting plate 4. At this time, under the action of the two tie rods 10 and the four tie rods 2 11, the two tie rods 10 and the four tie rods 2 11 generate a force opposite to the tension and realize the protection of the pressurizing cylinder 5. To ensure stability during the pressurization process, after the processing is completed, the pressurizing cylinder 5 is driven to drive the heating mold 7 to rise to a certain position, and the rodless cylinder 13 is driven. The rodless cylinder 13 pushes the material below the heating mold 7 to the lower die 12 below the cooling mold 8 through the push rod 14. The pressurizing cylinder 5 corresponding to the cooling mold 8 is driven to drive the cooling mold 8 to descend. The cooling mold 8 cooperates with the lower die 12 to process the material. After the processing is completed, the rodless cylinder 2 15 is driven. The rodless cylinder 2 15 can push the material below the cooling mold 8 to the operating platform 20 through the push rod 2 16.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
