Description

Technical Field

[0001] The utility model relates to the technical field of mold design, in particular to a semi-automatic demoulding mold for a connecting rod dust cover huff. Background Art

[0002] The demoulding method of the existing connecting rod dust cover huff mold is to use shoulder bolts to hoist the huff and slide it in the lower template chute, and manually open the huff. The structure of the existing connecting rod dust cover huff mold is as Figure 1 shown, including: a lower template, a lower die core is provided on the lower template, there is a huff between the lower die cores, a middle die lifting frame is also provided on the lower template, an upper template is provided on the middle die lifting frame, an upper die insert is provided on the upper template. When the product is demoulded, manual opening will cause uneven force, and the huff is prone to jamming when opened, thus affecting the quality of the product. Moreover, after the mold is vulcanized, the temperature of the mold is very high, and the danger coefficient of employees will also increase, thus greatly reducing the work efficiency of workers. Designing a connecting rod dust cover huff mold with higher productivity is imminent. Summary of the Utility Model

[0003] To solve the technical problems in the background art, the utility model proposes a semi-automatic demoulding mold for a connecting rod dust cover huff.

On the one hand, it is convenient to position the two groups of halves, and the positioning of the halves in the vertical direction can be realized when pressing down the middle mold.

[0008] Preferably, a reinforcing rib is provided at the bottom of the protrusion, and a positioning groove is formed on the lower template. The positioning groove matches the reinforcing rib, which is convenient for positioning the middle mold on the premise of ensuring the overall strength of the middle mold is increased.

Detailed description of the specific implementation

[0021] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar symbols represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0022] As Figures 2 - 5 Shown is a semi-automatic demolding mold for a connecting rod dust cover half-shell. A semi-automatic demolding mold for a connecting rod dust cover half-shell includes a lower template 1 and a strip-shaped half-shell installed on the lower template 1. The half-shell includes a first half 2 and a second half 3, and the first half 2 and the second half 3 are spliced. It also includes a lifting frame 4 arranged on the lower template 1. The lifting frame 4 is located on the side of the half-shell. A first driving pin 5 is provided on the first half 2, and a second driving pin 6 is provided on the second half 3. The ends of the first driving pin 5 and the second driving pin 6 away from the first half 2 and the second half 3 are connected to the lifting frame 4. Moving the lifting frame 4 upward through the first driving pin 5 and the second driving pin 6 causes the first half 2 and the second half 3 to move away from each other; the same as the prior art, it also includes an upper mold 7. The upper mold 7, the lower mold and the half-shell form a cavity. During the molding process, the upper mold 7 acts on the lifting frame 4 to prevent the lifting frame 4 from moving upward. When demolding, the upper mold 7 is removed and then the lifting frame 4 is moved upward. The lifting frame 4 can achieve the separation of the first half 2 and the second half 3 through the first driving pin 5 and the second driving pin 6, thereby realizing demolding. The original manual opening method of the half-shell is changed to a semi-automatic demolding method by the mutual sliding of the first driving pin 5 and the second driving pin 6 to change the two half-shells.

[0023] As Figure 4As shown, in some embodiments, specifically, there are at least two sets of half-molds. At least two sets of half-molds are arranged horizontally on the lower template 1, and a spacing groove is formed between any two adjacent sets of half-molds. It further includes a middle mold 8. The middle mold 8 is placed on the lifting frame 4 and the middle mold 8 has a protrusion 80, and the protrusion 80 matches the spacing groove.

[0024] As Figure 4 shown, preferably, the side surface of the protrusion 80 opposite to the half-mold is inclined gradually from top to bottom away from the half-mold in contact therewith, which is convenient for positioning the half-mold.

[0025] As Figure 4 shown, in some embodiments preferably, a reinforcing rib 800 is provided at the bottom of the protrusion 80, and a positioning groove 10 is formed on the lower template 1. The positioning groove 10 can be directly formed on the lower template 1 or on a backing plate on the lower template 1 as shown, and the positioning groove 10 matches the reinforcing rib 800.

[0026] In some embodiments specifically, the upper mold 7 is arranged on the middle mold 8. An upper mold insert 9 is provided on the upper mold 7, and a lower mold insert 11 is provided on the lower template 1. The upper mold insert 9, the lower mold insert 11, the first half-mold 2 and the second half-mold 3 form a cavity.

[0027] Preferably, a first sliding groove 40 and a second sliding groove 41 are formed on the side surface of the lifting frame 4 opposite to the half-mold. A part of the first transmission pin 5 extends into the first sliding groove 40, and a part of the second transmission pin 6 extends into the second sliding groove 41. The first sliding groove 40 and the second sliding groove 41 are in an "eight" shape.

[0028] Preferably, the first transmission pin 5 and the second transmission pin 6 include a connecting portion 12 and a rotating portion 13. The connecting portion 12 of the first transmission pin 5 is connected to the first half-mold 2, and the connecting portion 12 of the second transmission pin 6 is connected to the second half-mold 3. The rotating portion 13 is horizontally rotatably installed on the connecting portion 12. The rotating portion 13 of the first transmission pin 5 is slidably connected to the first sliding groove 40, and the rotating portion 13 of the second transmission pin 6 is slidably connected to the second sliding groove 41. Preferably, the connecting portion 12 is connected to the half-mold by a threaded manner.

[0029] After the product is vulcanized, the mold is opened. The upper die insert 9 moves upward with the upper die 7 and separates from the half die. Subsequently, the middle die 8 plate moves upward to open the outer side of the half die to prepare for the automatic opening of the half die. At this time, the lifting lugs on both sides of the lifting frame 4 are lifted to move it upward. Under the reaction force, the half die moves downward relative to the lifting frame 4. Since the first chute 40 and the second chute 41 of the lifting frame 4 are distributed in a V shape, when the lifting frame 4 is lifted, both sides of the half die will open in opposite directions. When the first transmission pin 5 and the second transmission pin 6 move to the lowest positions of the first chute 40 and the second chute 41, it is the maximum opening position of the half die and also the best position for product demolding, thus realizing semi-automatic demolding of the half die. When closing the mold, the first transmission pin 5 and the second transmission pin 6 automatically return along the tracks of the first chute 40 and the second chute 41. This structure not only facilitates demolding without jamming and improves production efficiency, but also ensures product quality.
