Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a three-plate mold material head anti-rotation structure. Background Technology

[0002] In the current mold design, the sprue of the three-plate mold is hung on the stripper plate by a main channel. After injection molding is completed, the sprue needs to be removed from the stripper plate for the next production. However, since the sprue may rotate around the gate, the sprue that is produced can easily move when it is placed on the stripper plate. This often results in the robot arm missing the target when removing it, causing damage to the mold during the next production.

[0003] For example, a patent application with publication number CN202491380U, entitled "An Automatic Ejection Structure for the Sprue Head of a Three-Plate Injection Mold and a Three-Plate Mold with the Structure," was published on October 17, 2012. The patent includes: a panel; a stripper plate that can slide longitudinally below the panel; a stationary template that can slide longitudinally below the stripper plate; a pusher plate that can slide longitudinally below the stationary template; and a moving template. At least one molding cavity is provided between the pusher plate and the stationary template, and a sprue head cavity is provided between the stationary template and the stripper plate. The molding cavity and the sprue head cavity are connected, and the sprue head cavity is connected to the gating gate. Above the sprue head cavity, when the sprue head needs to be removed from the stripper plate after injection molding, the sprue head may rotate around the gating gate, affecting subsequent work efficiency. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a three-plate mold head anti-rotation structure to solve the problem of affecting subsequent work efficiency.

[0005] To achieve the above objectives, this utility model provides a three-plate mold material head anti-rotation structure, including a stripper plate disposed in the mold of the three-plate mold, a pouring gate provided on the stripper plate, a positioning hole located on one side of the pouring gate on the lower end face of the stripper plate, a material head disposed below the stripper plate, a pouring pipe disposed on the material head for penetrating the pouring gate, and an anti-rotation post disposed on the material head in cooperation with the positioning hole.

[0006] Optionally, the number of positioning holes is two, and the two positioning holes are symmetrically arranged about the pouring port.

[0007] Optionally, a slot is provided on the side wall of the anti-rotation column, and a stop rod is connected in the slot through an elastic element. The end of the stop rod is provided with a chamfered head, which extends out of the slot.

[0008] Optionally, the chamfering head extends out of the slot on the side away from the elastic member, and the chamfering head is located within the slot on the side closer to the elastic member.

[0009] Optionally, the elastic element is an elastic spring.

[0010] Optionally, a track is provided in the slot, and the abutment is slidably connected to the track.

[0011] Optionally, the inner wall of the positioning hole is provided with a side groove located on the lower end face of the stripper plate, and the side groove is configured to cooperate with the chamfer head.

[0012] The beneficial effects of this utility model are as follows: The anti-rotation structure for the material head of the three-plate mold provided by this utility model prevents the material head from rotating on the stripper plate by cooperating with the anti-rotation post on the material head and the positioning hole on the stripper plate. In this way, the material head is not only hung on the stripper plate through the main channel, but also stays in the same position on the stripper plate. When the robot arm picks it up later, it is easy to grab the material head, thus improving work efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 4 As shown, a three-plate mold anti-rotation structure for a material head includes a stripper plate 2 disposed in the mold of a three-plate mold. A panel 1 is disposed above the stripper plate 2, a stationary template 7 is disposed below the stripper plate 2, and a movable template is fitted below the stationary template 7. A pouring gate 3 is provided on the stripper plate 2, and a positioning hole 4 is provided on the lower end face of the stripper plate 2 located on one side of the pouring gate 3. A material head 5 is disposed below the stripper plate 2, and a main channel for penetrating the pouring gate 3 is provided on the material head 5. An anti-rotation post 6 is provided on the material head 5 and is fitted with the positioning hole 4.

[0023] like Figure 5 As shown, Figure 5 This is a schematic diagram of the material handling head 5 of the robotic arm 8.

[0024] By cooperating with the anti-rotation post 6 on the material head 5 and the positioning hole 4 on the stripper plate 2, the material head 5 is prevented from rotating on the stripper plate 2. In this way, the material head 5 is not only hung on the stripper plate 2 through the main channel, but also stays in the same position on the stripper plate 2. When the robot arm 8 takes it out later, it is easy to grab the material head 5, which improves the work efficiency.

[0025] There are two positioning holes 4, which are symmetrically arranged about the pouring port 3 to prevent the material head 5 from rotating on the stripping plate 2 and to avoid the produced material head 5 from staying at a position on the stripping plate 2 that is inconsistent with its previous position. This makes it less likely to miss when the robot arm 8 takes it out, thus improving work efficiency.

[0026] The anti-rotation post 6 has a slot on its side wall. A stop rod is connected to the slot through an elastic element. The end of the stop rod is provided with a chamfered head. The chamfered head extends out of the slot. When the anti-rotation post 6 is inserted into the positioning hole 4, the chamfered end of the chamfered head contacts the positioning hole 4 and then extends into the slot. After the anti-rotation post 6 is inserted into the positioning hole 4, the chamfered head abuts against the inner side wall of the positioning hole 4, which facilitates the cooperation between the anti-rotation post 6 and the positioning hole 4 and improves the positioning of the material head 5.

[0027] The chamfered head extends out of the slot on the side away from the elastic element, while the chamfered head is located inside the slot on the side closer to the elastic element, to prevent the anti-rotation post 6 from not fitting with the positioning hole 4 due to the chamfered head.

[0028] The elastic element is an elastic spring, which facilitates the elastic connection between the push rod and the slot.

[0029] A track is provided within the slot, and the abutment is slidably connected to the track.

[0030] The inner wall of the positioning hole 4 is provided with a side groove located on the lower end face of the stripper plate 2. The side groove is configured to cooperate with the chamfer head. After the anti-rotation post 6 is inserted into the positioning hole 4, the chamfer head abuts against the side groove on the inner wall of the positioning hole 4, which facilitates the cooperation between the anti-rotation post 6 and the positioning hole 4, and between the chamfer head and the side groove, thereby improving the positioning of the material head 5.

[0031] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
