Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a quick positioning structure for a pin in a license plate light base mold. Background Technology

[0002] The license plate light base is made of plastic, and complex license plate light bases can be quickly manufactured using a license plate light base mold.

[0003] The license plate light base has metal pins, so the pins need to be pre-attached to the mold during the injection molding process.

[0004] In current industrial production processes, workers typically insert pins directly into the mold, and the accuracy of the pin connection position depends entirely on the worker's experience. This process is not only inefficient but also results in poor pin positioning stability, ultimately failing to guarantee the quality of the finished license plate light base. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing a positioning structure that can quickly position the pin in the license plate light base mold.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A quick positioning structure for a pin in a license plate light base mold is disclosed. The license plate light base mold includes a body with a molding cavity that matches the mold. The quick positioning structure comprises a first positioning block, a second positioning block, and an extrusion assembly. The body has a guide groove adjacent to the molding cavity. The first positioning block is connected to the guide groove. The first positioning block is cylindrical, with one end serving as a pre-positioning end and the other end as an extrusion end. When the lower end of the pin is inserted into the molding cavity, the upper end of the pin can be initially positioned at the pre-positioning end.

[0008] The aforementioned positioning block two is inserted inside positioning block one, with one end of positioning block two being the working end and the other end being the extrusion end two.

[0009] The aforementioned extrusion assembly is connected to the end of the main body. The extrusion assembly has a tendency to push extrusion end one and extrusion end two. Under the pushing action of the extrusion assembly, the working end can abut against the upper end of the pin and position the pin.

[0010] The quick-positioning structure for the pin in this license plate lamp base mold innovatively places the pin through the molding cavity and then pre-positions it using a positioning block. During this process, since the pin is only pre-positioned, it is not yet correctly positioned on the corresponding part of the mold.

[0011] Next, the positioning block two pushes the pin with external force, and the pushed pin enters the set position on the mold. In other words, at this time, the pin is precisely positioned on the mold.

[0012] Both positioning block one and positioning block two are pushed by the extrusion assembly, thus enabling rapid positioning of the pin.

[0013] Specifically, the pre-positioning end of positioning block one initially positions the upper part of the pin. After positioning block two moves, its working end abuts against the upper end of the pin. Therefore, the above structure enables rapid and accurate positioning of the pin.

[0014] Of course, the extrusion assembly applies pressure to extrusion end one and extrusion end two to ensure that positioning block one and positioning block two can move stably to the set position.

[0015] In the quick positioning structure of the pin in the license plate lamp base mold described above, the pre-positioning end has a recessed positioning groove that matches the upper end of the pin.

[0016] Stable initial positioning can be achieved after the upper end of the pin is embedded in the positioning groove.

[0017] In the aforementioned quick positioning structure for inserting pins in the license plate light base mold, the working end has a pushing part embedded in the positioning groove.

[0018] After the positioning block 2 moves, it can stably push the upper end of the insert pin through the pushing part, and make the insert pin stably move to the preset position of the mold.

[0019] In the quick positioning structure for inserting pins in the aforementioned license plate light base mold, the positioning groove port has a smoothly transitioned inlet portion.

[0020] The design of the inlet section allows the upper end of the pin to be stably embedded in the positioning groove.

[0021] The inlet section is a chamfer at the end of the positioning groove. Of course, depending on the actual situation, it is also feasible to make the inlet section rounded.

[0022] In the aforementioned quick positioning structure for inserting pins in the license plate light base mold, the extrusion assembly includes a pressure block and an inclined guide post. The inclined guide post is obliquely connected to the body, the pressure block is sleeved on the inclined guide post, and the pressure block abuts against extrusion end one and extrusion end two.

[0023] After the pressure block pushes and squeezes the first and second extrusion ends, it can make the first and second positioning blocks move stably to the set position.

[0024] In the quick positioning structure for inserting pins in the aforementioned license plate light base mold, both the first extrusion end and the second pressure end are inclined slopes, and their inclination directions and inclination angles are the same.

[0025] In the quick positioning structure for inserting pins in the aforementioned license plate light base mold, the pressure block has an inclined contact surface, which contacts the first extrusion end and the second extrusion end.

[0026] After the contact surface comes into contact with the first and second extrusion ends, it can stably push the first and second positioning blocks.

[0027] In the quick positioning structure for inserting pins in the aforementioned license plate light base mold, a contact piece is fixedly connected to the pressure block, and the aforementioned contact surface is located on the contact piece.

[0028] The additional contact piece can be replaced individually after it wears out, effectively reducing the cost of using the mold.

[0029] Compared with existing technologies, the quick positioning structure of the pin in the license plate lamp base mold of this invention has a positioning block 1 for pre-positioning the pin in the molding cavity and a positioning block 2 for accurately positioning the pin at the positioning block 1. It can be seen that the connection between the pin and the mold is not only fast but also accurate, which effectively improves the work efficiency.

[0030] Meanwhile, the connection between positioning block one and positioning block two effectively improves the structural compactness of the entire positioning structure and has high practical value. Attached Figure Description

[0038] like Figure 1 As shown, the license plate light base mold includes a body 1, which has a molding cavity 1a that matches the license plate light base mold.

[0039] like Figure 2 and Figure 3 As shown, the quick positioning structure for the pin in the license plate lamp base mold includes a positioning block 1 2, a positioning block 2 2, and an extrusion assembly. The main body 1 has a guide groove 1b adjacent to the molding cavity. The positioning block 1 2 is connected to the guide groove. The positioning block 1 2 is cylindrical, with one end being a pre-positioning end 2a and the other end being an extrusion end 2b. When the lower end of the pin 7 is embedded in the molding cavity 1a, the upper end of the pin 7 can be initially positioned at the pre-positioning end 2a.

[0040] The aforementioned positioning block 2 3 is inserted inside positioning block 1 2, with one end of positioning block 2 3 being the working end 3b and the other end of positioning block 2 3 being the extrusion end 2 3a. Both the working end 3b and the extrusion end 2 3a extend out of positioning block 1 2.

[0041] The aforementioned extrusion assembly is connected to the end of the body 1. The extrusion assembly tends to push the extrusion end 2b and the extrusion end 3a. Under the pushing action of the extrusion assembly, the working end 3b can abut against the upper end of the pin 7 and position the pin 7.

[0042] The prepositioning end 2a has a recessed positioning groove 2a1 that matches the upper end of the pin 7.

[0043] The working end 3b has a pushing part 3b1 embedded in the positioning groove.

[0044] The positioning groove 2a1 has a smoothly transitioned inlet 2a11 at its port.

[0045] The extrusion assembly includes a pressure block 4 and an inclined guide post 5.

[0048] A contact piece 6 is fixedly connected to the pressure block 4, and the contact surface 6a is located on the contact piece 6.

[0049] The quick-positioning structure for the pin in this license plate lamp base mold innovatively places the pin through the molding cavity and then pre-positions it using a positioning block.

[0050] Next, the positioning block two pushes the pin with external force, and the pushed pin enters the set position on the mold. In other words, at this time, the pin is precisely positioned on the mold.

[0051] In this embodiment, in order to increase stability, the bottom of the pressure block 4 has a recessed positioning notch 4a, and the body 1 has a protruding positioning head 1c. When the positioning notch 4a covers the positioning head 1c, the contact piece 6 can stably abut against the positioning block 2 and the positioning block 3.

It also includes a sheet-like contact piece 7, that is, in the mold-locked state, the contact piece 6 abuts against the positioning block 2 and the positioning block 3, while the contact piece 7 abuts against the contact portion 1c1. At this time, the contact piece 7 and the contact portion 1c1 maintain surface contact.

[0053] The aforementioned inclined guide post 5 is inserted through the positioning head 1c of the body 1, and the first contact piece 6 and the second contact piece 7 are located on both sides of the positioning head 1c.

[0054] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
