[0030] Embodiment 1

[0031] As Figure 1 、 Figure 2 shown, a template positioning structure applied to the HUD mold in this embodiment is applied to the mold for secondary mold closing. That is, after the first mold closing is completed, there is still a gap between the B plate 2 and the backing plate 3 under the action of the mold closing assembly; when the injection molding is completed and the pressure holding is carried out, the mold closing drive mechanism acts again for the second mold closing. At this time, the mold closing drive mechanism overcomes the elastic force of the mold closing assembly and pushes the backing plate 3 forward to contact the B plate 2, pressurizing the injection molded product to make the injection molded product pressed more tightly; it includes the A plate 1, the B plate 2, and the backing plate 3 installed on the B plate 2. A plurality of positioning structures are provided between the B plate 2 and the A plate 1 and the backing plate 3. In this embodiment, the number of positioning structures is two, which are respectively arranged on both side surfaces of the mold. Each positioning structure includes a first positioning portion 4 and a second positioning portion, and the first positioning portion 4 and the second positioning portion are mutually inserted and matched.

[0032] The first positioning portion 4 is arranged on the B plate 2, and the second positioning portion is arranged on the A plate 1 and the backing plate 3. The first positioning portion 4 is strip-shaped, and the length direction of the first positioning portion 4 is parallel to the mold closing direction of the mold; the middle part of the first positioning portion 4 is fixed on the B plate 2, and the two ends are respectively a first insertion portion 5 and a second insertion portion 6, which can be inserted into the second positioning portion. The first insertion portion 5 and the second insertion portion 6 are in the shape of regular cubes; the second positioning portion is a first slot 7 opened on the A plate 1 and a second slot 8 opened on the backing plate 3. The slot width of the first slot 7 matches the width of the first insertion portion 5, and the slot width of the second slot 8 matches the width of the second insertion portion 6.

[0033] Furthermore, the first positioning portion 4 is in the shape of a cuboid. An installation groove is formed on the B plate 2, and the first positioning portion 4 is fixed in the installation groove by screws. If the first positioning portion 4 is worn, it can be removed and replaced, which is convenient for replacement. Chamfers are provided at the heads of the first card insertion portion 5 and the second card insertion portion 6. The chamfers facilitate the insertion of the first card insertion portion 5 into the first card slot 7 and the second card insertion portion 6 into the second card slot 8. First pads 9 and second pads 10, third pads 11 and fourth pads 12 are detachably installed on the two side edges in the width direction of the first card slot 7 and the second card slot 8 respectively. The distance between the first pads 9 and the second pads 10 matches the width of the first card insertion portion 5, and the distance between the third pads 11 and the fourth pads 12 matches the width of the second card insertion portion 6. Since during the first mold closing, the first card insertion portion 5 is inserted into the first card slot 7 and the first card insertion portion 5 slides in the first card slot 7, the first card slot 7 will be worn over time, thus affecting the positioning accuracy of the positioning structure. When the first pads 9 and the second pads 10 are worn, the pads can be replaced without replacing the entire A plate 1. Similarly, during the second mold closing, the second card insertion portion 6 slides in the second card slot 8, and the second card slot 8 will be worn over time. The setting of the third pads 11 and the fourth pads 12 also facilitates the replacement of the worn parts without replacing the entire backing plate 3.

[0034] Embodiment 2

[0035] As Figure 3 、 Figure 4 shown, a template positioning structure applied to an HUD mold in this embodiment is applied to a mold for the first mold closing, and includes: an A plate 1, a B plate 2, and a backing plate 3 installed on the B plate 2. A plurality of positioning structures are arranged between the B plate 2 and the A plate 1. The number of the positioning structures is two, and they are respectively arranged on the two side surfaces of the mold; each positioning structure includes a first positioning portion 4 and a second positioning portion, and the first positioning portion 4 and the second positioning portion are in mutual card insertion and cooperation.

[0036] The first positioning portion 4 is provided on the B plate 2, and the second positioning portion is provided on the A plate 1. The first positioning portion 4 is strip-shaped, and the length direction of the first positioning portion 4 is parallel to the mold closing direction of the mold; one end of the first positioning portion 4 is fixed on the B plate 2, and the other end is the first clamping portion 5, which can be inserted into the second positioning portion. The first clamping portion 5 is in the shape of a regular cube; the second positioning portion is the first card slot 7 opened on the A plate 1, and the slot width of the first card slot 7 matches the width of the first clamping portion 5; the first positioning portion 4 is in the shape of a cuboid, and an installation groove is opened on the B plate 2. The first positioning portion 4 is fixed in the installation groove by screws. If the first positioning portion 4 is worn, it can also be removed and replaced, which is convenient for replacement. A chamfer is provided at the head of the first clamping portion 5, and the chamfer is provided to facilitate the insertion of the first clamping portion 5 into the first card slot 7. The first cushion block 9 and the second cushion block 10 are respectively detachably installed on both sides of the first card slot 7 in the width direction. The distance between the first cushion block 9 and the second cushion block 10 matches the width of the first clamping portion 5. Since when the mold is closed for the first time, the first clamping portion 5 is inserted into the first card slot 7 and the first clamping portion 5 slides in the first card slot 7, the first card slot 7 will be worn after a long time, which will affect the positioning accuracy of the positioning structure. When the first cushion block 9 and the second cushion block 10 are worn, only the cushion blocks need to be replaced, and there is no need to replace the entire A plate 1.

[0037] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
