Description

Technical Field

[0001] The invention belongs to the technical field of molds, and in particular relates to a mold and a use method thereof. Background Art

[0002] Molds, as a kind of process equipment used in industrial production, have the core function of forming parts or products with certain shape and size requirements through specific shapes. Among various types of molds, plastic molds are an important type of molds. They refer to injecting liquid in a molten state into the mold, and then cooling the liquid through cooling molding after the liquid is fully distributed in the mold, and then forming a finished product of the target shape in the mold to complete the molding effect;

[0003] However, the molds in the prior art can only achieve the effect of simply providing a molding space for the liquid. When the shape of the finished product to be molded is relatively special, and the molding space inside the mold cannot meet the requirements of uniform liquid flow, it is very easy to affect the subsequent plastic molding effect and thus affect the processing results. Summary of the invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a mold and a method for using the same, so that the liquid added to the mold can flow evenly into the molding space in the mold to ensure the subsequent molding effect of the finished product.

[0006] It also includes a friction wheel A rotatably connected to the pushing part, a slide frame is slidably connected to the pushing part, a friction wheel B is rotatably connected to the slide frame, and the friction wheel A can drive the friction wheel B to rotate.

[0007] It also includes a vertical rod, which is connected to a sliding plate. The sliding plate is provided with a friction strip, and the friction strip can contact the friction wheel B.

[0008] It also includes a push rod slidably connected to the pushing part, one end of the hinged rod is hinged on the push rod, and the other end of the hinged rod is hinged on the friction wheel B. The vertical rod is slidably connected to the sliding plate, a first compression spring is fixed between the vertical rod and the sliding plate, a matching rod is fixed on the sliding plate, a friction plate is fixed on the sliding plate, and the push rod can contact the friction plate.

[0009] The method for using the mold comprises the following steps:

[0010] Step 1: Place the mold that can shape the material on the containing part, and then operate the clamping plate to slide on the containing part to clamp it;

[0011] Step 2: operate the push part to slide on the bottom plate, and after the push part stops sliding, operate the slide to slide on the push part until the friction wheel B contacts the friction wheel A;

[0012] Step 3: injecting liquid into a mold capable of molding the material;

[0013] Step 4: After the liquid is completely distributed in the molding space in the mold, the push part is slid in the reverse direction to reset and complete the auxiliary process. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-3 and Figure 8 As shown:

[0024] It includes a base plate 101, a containing part 201 is rotatably connected to the base plate 101, a pushing part 103 is slidably connected to the base plate 101, a bottom baffle 203 and a side baffle 204 are fixedly connected to the containing part 201, the pushing part 103 can contact the lower side of the containing part 201, a first motor is fixedly connected to the base plate 101, a first screw is fixedly connected to the output shaft of the first motor, and the first screw is threadedly connected to the pushing part 103.

[0025] When in use, the mold capable of molding the material is placed on the containing part 201. The bottom baffle 203 and the side baffle 204 are arranged so that the mold can be against the bottom baffle 203 and the side baffle 204, which is convenient for the stable placement of the mold. Then, the liquid to be molded is continuously injected into the mold. During the liquid injection process, the pushing part 103 can be operated to slide on the bottom plate 101, and then the pushing part 103 is used to push the containing part 201 to rotate on the bottom plate 101, so that the mold placed on the containing part 201 is tilted to a suitable angle as a whole, so that the liquid added to the mold can flow evenly into the molding space in some molds with special shapes, avoiding the situation that the liquid cannot be evenly distributed in the molding space when the mold is placed flat due to the special shape of the finished product to be molded, thereby affecting the subsequent molding effect of the finished product, thereby providing a stable guarantee for the molding effect of the mold;

[0026] When operating the pushing part 103 to slide, the staff can operate the pushing part 103 to slide a suitable distance and stay at a suitable position for a suitable time according to actual usage requirements, thereby controlling the tilt angle of the containing part 201 and the tilting time of the containing part 201, while providing stable protection for the mold molding effect, avoiding the situation where the mold tilts too much or the tilting time is too long, which has a negative impact on the molding effect.

[0027] like Figure 4 As shown:

[0028] It also includes a friction wheel A107 rotatably connected to the pushing part 103, the pushing part 103 is slidably connected to the slide 301, the slide 301 is rotatably connected to the friction wheel B302, the friction wheel A107 can drive the friction wheel B302 to rotate, the pushing part 103 is fixedly connected to a first electric push rod capable of pushing the slide 301 to slide, and the pushing part 103 is fixedly connected to a second motor capable of driving the friction wheel A107 to rotate.

[0029] During the operation of the equipment, the friction wheel A107 continuously rotates on the pushing part 103. When the pushing part 103 slides to a suitable distance according to actual use requirements and stays at the position, the slide 301 automatically slides on the pushing part 103, so that the friction wheel B302 contacts the friction wheel A107. Then, as the friction wheel A107 continues to rotate, the friction wheel A107 continuously drives the friction wheel B302 to rotate. At this time, by monitoring the time when the friction wheel B302 rotates and the continuous rotation time of the friction wheel B302, the inclination angle of the containing part 201 and the inclination time of the containing part 201 can be sensed, and the position of the pushing part 103 and the residence time of the pushing part 103 at this time can be tested to see whether they meet the target production requirements, thereby avoiding possible deviations in the tilting process of the mold due to control program failures. When the above-mentioned unexpected situation occurs, it can be discovered and corrected in time, thereby further ensuring the stable progress of the processing;

[0030] An angle sensor based on physical effects such as resistance, capacitance, inductance, magnetoresistance, Hall effect or photoelectric effect is used. When the moving end of the angle sensor rotates, the above-mentioned physical effects will change, and then the change will be converted into a measurable electrical signal, thereby completing the test operation of the rotation condition. The rotation condition monitoring operation of the friction wheel B302 can be completed by connecting the angle sensor to the slide 301 and connecting the friction wheel B302 to the rotating end of the angle sensor. The angle sensor can detect the situation in time when the friction wheel B302 rotates, which brings convenience to subsequent use.

[0031] like Figure 5 As shown:

[0032] It also includes a vertical rod 401, and a sliding plate 402 is connected to the vertical rod 401. The sliding plate 402 is provided with a friction strip, and the friction strip can contact the friction wheel B302.

[0033] When the pushing part 103 moves, the slide 301 will be driven to move synchronously with the pushing part 103. During this process, the friction wheel B302 will always be in contact with the sliding plate 402, so that the friction wheel B302 will always rotate on the slide 301. At this time, the angle sensor should be able to continuously obtain the electrical signal of the rotation of the friction wheel B302, and then use this process to detect the operation of the angle sensor, thereby ensuring the accuracy of the subsequent measurement results of the angle sensor.

[0034] like Figure 5 As shown:

[0035] It also includes a push rod 303 slidably connected to the pushing part 103, one end of a hinged rod 304 is hinged on the push rod 303, the other end of the hinged rod 304 is hinged on the friction wheel B302, the vertical rod 401 is slidably connected to the sliding plate 402, a first compression spring is fixed between the vertical rod 401 and the sliding plate 402, a friction plate 403 is fixed on the sliding plate 402, and the push rod 303 can contact the friction plate 403.

[0036] Under normal circumstances, the first compression spring will make the friction plate 403 press against the friction wheel B302, providing protection for the angle sensor measurement process. When the friction wheel B302 is needed to measure the tilting process of the containing part 201 and operate the slide 301 to slide on the pushing part 103, the slide 301 will automatically drive one end of the hinged rod 304 to move. At this time, the other end of the hinged rod 304 can automatically transmit the transmission to make the push rod 303 slide downward on the pushing part 103. During this process, the push rod 303 will press the matching rod 404 to make the sliding plate 402 slide downward on the vertical rod 401, thereby separating the friction plate 403 from the friction wheel B302, thereby avoiding the friction plate 403 from hindering the rotation of the friction wheel B302 during the subsequent measurement of the tilting process of the containing part 201, thereby ensuring the accuracy of the subsequent measurement results.

[0037] like Figure 2 As shown:

[0038] It also includes a clamping plate 206 slidably connected to the containing portion 201 , and a second electric push rod is fixed to the containing portion 201 and can push the clamping plate 206 to slide.

[0039] After the mold is placed on the container 201, the clamp 206 can be slid to cooperate with the bottom baffle 203 and the side baffle 204 to stably clamp the mold, ensuring that the mold can be stably located on the upper side of the container 201 when the container 201 is tilted, bringing convenience to subsequent use.

[0040] like Figure 3 , Figure 4 and Figure 8 As shown:

[0041] The pushing portion 103 is fixedly connected with an arc portion 104 .

[0042] When the pushing portion 103 is used to push the containing portion 201 to rotate, the arc surface portion 104 will first contact the containing portion 201, and then as the pushing portion 103 continues to rotate, the containing portion 201 will gradually rotate to a higher angle, so that the containing portion 201 gradually rotates to an angle where the pushing portion 103 can smoothly enter the lower side of the containing portion 201. The setting of the arc surface portion 104 can further increase the control over the rotation angle of the containing portion 201, so that if in actual use, only a smaller angle of rotation of the containing portion 201 is required to meet production needs, the arc surface portion 104 can meet the need to push the containing portion 201 to rotate a small angle, thereby further bringing convenience to actual use.

[0043] like Figure 7 As shown:

[0044] The bottom plate 101 is provided with a rectangular groove 105 .

[0045] A blowing device can be connected to the lower side of the base plate 101 by tightening bolts on the base plate 101. After the liquid is evenly distributed in the molding space of the mold, the blowing device can be started to allow the gas to quickly contact the lower side of the mold through the rectangular groove 105, thereby performing auxiliary cooling operations on the lower side of the mold, thereby improving the cooling and molding efficiency of the liquid in the mold, and further bringing convenience to practical use.

[0046] As shown in 7:

[0047] The containing portion 201 is provided with a plurality of through holes 202 .

[0048] The provision of the plurality of through holes 202 can further facilitate the gas entering from the rectangular groove 105 to contact the lower side of the mold, thereby further facilitating the subsequent auxiliary cooling operation.

[0049] like Figure 7 As shown:

[0050] It also includes a T-shaped rod 106 slidably connected to the bottom plate 101 , a cylindrical rod 205 is fixedly connected to the containing portion 201 , and a third electric push rod is fixedly connected to the bottom plate 101 and can push the T-shaped rod 106 to slide.

[0051] If during actual use, the power driving the pushing portion 103 to slide suddenly fails, causing the containing portion 201 to be unable to rotate normally, the T-shaped rod 106 can be operated to slide on the bottom plate 101, and then the T-shaped rod 106 can be used to push the cylindrical rod 205, so that the T-shaped rod 106 actively drives the containing portion 201 to rotate upward, thereby achieving the effect of temporarily driving the containing portion 201 to rotate, thereby avoiding interruption of the processing process.

[0052] The method for using the mold comprises the following steps:

[0053] Step 1: Place a mold capable of molding the material on the container 201, and then operate the clamping plate 206 to slide on the container 201 to clamp the material;

[0054] Step 2: operate the push part 103 to slide on the bottom plate 101, and after the push part 103 stops sliding, operate the slide 301 to slide on the push part 103 until the friction wheel B302 contacts the friction wheel A107;

[0055] Step 3: injecting liquid into a mold capable of molding the material;

[0056] Step 4: After the liquid is completely distributed in the molding space in the mold, the pusher 103 is slid in the reverse direction to reset and complete the auxiliary process.
