Description

Technical Field

[0001] The utility model relates to the field of injection mold equipment, in particular to a pouring auxiliary device for an injection mold. Background Art

[0002] In the injection molding industry, the heating and melting equipment melts the plastic raw materials put into the bin during production, and then inputs them into the raw material inlet (gate) of the plastic product mold located at a lower position through a fluid pipeline. The fluid raw materials entering the mold through the mold raw material inlet are subsequently cooled to form a plastic product (the inner and outer cavities of the mold are subsequently separated to obtain the finished plastic product).

[0003] In the prior art, the plastic product mold is generally fixed at the lower end of the discharge port of the hot melt equipment. After the pouring and cooling, the plastic product mold is removed (or the operation is performed without moving the original position), and then the mold is opened to take out the poured plastic product. The authorized patent of my country with patent number "201620269395.X" and patent name "A plastic product mold" records that "the utility model not only has good strength, but also does not cause scratches on the fixed mold and does not produce parting lines. The plastic product obtained is a high-gloss mirror surface, which can meet the quality requirements of the shell of communication products." As can be seen from the above, although the comparative patent has achieved the technical effect of the invention described in it, it is limited by the structure. Like other plastic product molds in the field, it is in a fixed state during casting, that is, it relies on the hot-melt plastic fluid output by the heating and melting equipment and its own flow to fill the internal molding cavity of the plastic product mold. Since the fluidity of the hot-melt plastic fluid is affected by the temperature and hot-melt state, especially when the internal structure of the plastic product mold is relatively complex and there are relatively many channels to flow through, it is impossible to ensure that the fluid can effectively and completely fill the internal cavity of the mold. In this way, there is a probability of voids appearing inside the finished mold after subsequent casting, which will have an adverse effect on the final quality of the product. In summary, it is particularly necessary to provide a plastic product mold device that can achieve the best molding quality as possible. Utility Model Content

[0004] In order to overcome the drawbacks of existing plastic product molds due to structural limitations as described in the background, the utility model provides a casting auxiliary device for an injection mold based on a plastic product mold body, which can conveniently fix the plastic product mold body before pouring, and can control the plastic product mold body to be in a rotating and vibrating state during and after pouring, so that the molten fluid can fill its interior as evenly as possible, thereby providing favorable technical support for improving product quality.

[0007] Furthermore, the inner sides of the two contact sheets and the outer sides of the two ferrules are in electrical contact and conduction.

[0008] Furthermore, the lower end of the support plate is spaced apart from the upper end of the cylinder.

[0009] Furthermore, the shape of the inner side end of the fixing shell matches the shape of the outer side end of the plastic product mold body, and a fixing screw is provided at the outer side end of the fixing shell.

[0010] Furthermore, each set of guiding support mechanism includes a supporting column and a supporting roller, both side ends of the supporting roller are rotatably mounted on the upper end of the supporting column, and the lower end of the supporting column is mounted on the lower end of the lower fixed plate, and the outer side of the upper end of the supporting roller of the guiding support mechanism and the lower end of the supporting plate are respectively rotatably contacted.

[0011] Compared with the prior art, the utility model has the following beneficial effects: (1) The utility model is based on the plastic product mold body, and the two sets of fixed shells can effectively fix the mold body. The gate of the mold body is located at the lower end of the fluid pipeline of the heating and melting equipment. During or after pouring, the staff can control the vibration motor to vibrate the mold body through the power switch, and can drive the mold body to rotate through the motor reduction mechanism. Under the combined action of rotation and vibration, the molten fluid can fill the interior of the mold body as evenly as possible, thereby improving the quality of plastic products; (2) Under the rotation support of the support rollers of the three sets of guide support mechanisms, the support plate and the upper mold body rotate more smoothly, and the shaft speed of the motor reduction mechanism can be adjusted through the voltage adjustment mechanism, and the control is more convenient (the speed of the mold body can be conveniently selected, and a better molten raw material pouring effect can be achieved at the corresponding appropriate speed). In summary, the utility model has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The insulating tube 63 is tightly sleeved outside the lower end of the rotating shaft of the motor reduction mechanism M1. There are two rings 61 and two contact pieces 62 respectively. The two rings 61 are tightly sleeved on the outside of the insulating tube 63 at a distance from each other. A plastic insulating seat 64 is installed on the right side of the upper end of the shell of the motor reduction mechanism M1.

At the lower end of the lower fixing plate 1, the power input terminals 1 and 2 of the voltage regulating mechanism W1 and the right ends of the two contact pieces X (62) are connected in series with the two poles of the AC 220V power supply through wires, respectively, through a power switch, and the power output terminals 3 and 4 of the voltage regulating mechanism W1 are connected with the power input terminal of the motor reduction mechanism M1 through wires, respectively. The voltage regulating mechanism W1 (the handle is located at the outer end of the barrel 2 for easy adjustment) is installed in the component box 7 at the lower right end of the lower fixing plate, and the wires connected with the voltage regulating mechanism W1 are led out through the opening at the lower right side end of the barrel.

[0017] Figure 1 , 2As shown in , 3, the inner sides of the left ends of the two contact pieces 62 and the outer sides of the front ends of the two ferrules 61 are in electrical contact and conduction. The lower end of the support plate 3 is spaced apart from the upper end of the cylinder 2. The shape formed by the inner ends of the two sets of fixed shells 4 matches the shape of the outer ends of the plastic product mold body. The spacing between the two sets of fixed shells 4 is slightly larger than the outer diameter of the plastic product mold body. There is a through thread hole in the middle of the outer ends of the two sets of fixed shells, and a manual fixing screw 41 is threadedly installed at the outer end of the thread hole (tightening the mold body, otherwise loosening the mold body). Each set of guiding support mechanism 5 includes a supporting column 51 and a supporting roller 52. The shafts in the middle of both side ends of the supporting roller 52 are respectively tightly sleeved in the inner rings of the bearings of the two bearing seats 53. The outer lower ends of the two bearing seats 53 are respectively installed on both sides of the upper end of the supporting column 51 by bolts, and the lower end of the supporting roller 52 is spaced apart from the upper end of the supporting column 51. The lower end of the supporting column 51 is welded to the lower end of the lower fixed plate 1. The outer sides of the upper ends of the supporting rollers 51 of the three sets of guiding support mechanisms are respectively in rotational contact with the lower ends of the supporting plates 3.

[0018] Figure 1 , 2As shown in Figure 3, the new type is based on the plastic product mold body and has all the functions of plastic product molds (it mainly plays the role of casting plastic products. During production, the plastic raw materials put into the bin are melted by the heating and melting equipment, and then input into the raw material inlet (gate) of the plastic product mold body located at a lower position through the fluid pipeline. The fluid raw materials entering the mold through the mold raw material inlet are subsequently cooled to form a plastic product, and the inner and outer mold cavities of the mold are subsequently separated to obtain the finished plastic product. The above is the existing mature technology. This application does not provide any protection for the structure and working process of the plastic product mold body. This application protects the technical solution of the plastic product mold body to improve the quality of plastic products after casting). Before casting, the staff puts the mold body on the support plate 3 and between the inner sides of the two sets of fixed shells 4, and then the staff tightens the two manual fixing screws 41. The inner ends of the two manual fixing screws 41 are in close contact with the outer ends of the mold body to fix it (the manual fixing screws 41 can be loosened later to remove the mold body). The gate of the mold body is located at the lower end of the fluid pipeline of the heating and melting equipment. During or after pouring, the staff turns on the power switch, so that the voltage regulating mechanism W1 is powered on and its power output end outputs power to the power input end of the motor reduction mechanism M1. At the same time, the 220V power supply enters the power input end of the two sets of vibration motors M2 respectively through two contact pieces X and a ferrule T (61) (when the mold body, the vibration motor and the ferrule rotate, the contact piece is inactive, which ensures that the power supply can enter the power input end of the vibration motor M2 when the mold body rotates). In this way, the two sets of vibration motors M2 and the motor reduction mechanism M1 are powered on and work at the same time. After the two sets of vibration motors M2 are powered on and work, they can vibrate the fluid raw materials entering the mold body, and the motor reduction mechanism M1 can drive the mold body to rotate. Under the action of vibration and rotation, the fluid raw materials entering the mold body can make the melted fluid fill the interior of the mold body as evenly as possible, thereby improving the quality of subsequent plastic products. Under the rotational support of the support rollers 51 of the three sets of guide support mechanisms on the lower end of the support plate 3, the support plate 3 and the upper mold body rotate more smoothly (when the support plate rotates, the support rollers 51 will rotate). Specifically, when the staff adjusts the output power of the large voltage adjustment mechanism W1, or adjusts the output power of the 3rd and 4th pins of the low voltage adjustment mechanism W1, the shaft speed of the motor reduction mechanism M1 will become faster or slower, so that the speed of the mold body will change or slow down, and the control will be more convenient (it is convenient to select the speed of the mold body and achieve better molten raw material casting effect at the corresponding appropriate speed; for example, if the mold has a small shape and the centrifugal force is small, the speed can be relatively adjusted to a high speed, otherwise it can be adjusted to a low speed to ensure the stable operation of the mold body). Figure 2 Among them, the power of vibration motor M2 is 500W; the motor reduction mechanism M1 is a finished product of motor gear coaxial reducer with a power of 4KW; the voltage regulation mechanism W1 is a motor speed regulator of model TL-4000w.
