Technical Field
[0001] This utility model relates to the field of mold structure technology, specifically a two-way demolding slider mechanism for grooved products that has a simple structure, good demolding effect, high demolding efficiency, and can achieve two-way demolding. Background Technology
[0002] As is well known, during the injection molding process, the product has grooves, and lateral demolding is required during the demolding process. Therefore, two modules are needed: one module to achieve lateral demolding and the other module to achieve vertical demolding of the grooves. Demolding in multiple directions requires multiple structures to achieve the demolding action. Existing demolding structures have problems such as complex structure, poor demolding effect, low demolding efficiency, and inability to achieve bidirectional demolding at the same time. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bidirectional demolding slider mechanism for grooved products that has a simple structure, good demolding effect, high demolding efficiency, and can achieve bidirectional demolding.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A bidirectional demolding slider mechanism for grooved products is characterized in that the slider mechanism includes a lateral pull block, a lower connecting block, and an upper sliding block. The front sides of the lower connecting block and the upper sliding block are provided with lateral forming cavities, the upper end face of the upper sliding block is provided with a top forming cavity, the rear side of the lower connecting block is connected to the lateral pull block, the upper end face of the lower connecting block is provided with a downward sliding surface that slopes towards the front, and the lower end face of the upper sliding block is provided with an upper sliding surface that cooperates with the downward sliding surface. The upper sliding surface and the downward sliding surface are slidably connected. By pulling the lateral pull block, the lower connecting block moves backward while the upper sliding block moves downward.
[0006] The upper sliding block of this invention has a lower holding hole on its rear side with the same inclination angle as the sliding surface, and an upper holding hole on its front side with the same inclination angle as the lower holding hole. The lower holding hole and the upper holding hole are built into a push spring, which assists the lower sliding block in moving downward.
[0007] The upper sliding block of this utility model has a sliding insert on its upper sliding surface, and a sliding protrusion on its side. The lower connecting block has a sliding insertion hole that mates with the sliding insert, and a sliding groove that mates with the sliding protrusion on its side. The sliding protrusion and the sliding groove are slidably connected.
[0008] The lateral pull block of this utility model has a shovel-fitting surface on its rear side, which is positioned to cooperate with the shovel chicken, and the shovel chicken drives the lateral pull block to further connect.
[0009] This utility model, due to the above-mentioned structure, has the advantages of simple structure, good demolding effect, high demolding efficiency, and the ability to achieve bidirectional demolding. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings:
[0014] As shown in the attached figure, a bidirectional demolding slider mechanism for grooved products is characterized in that the slider mechanism includes a lateral pull block 1, a lower connecting block 2, and an upper sliding block 3. The front sides of the lower connecting block 2 and the upper sliding block 3 are provided with lateral forming cavities, the upper end face of the upper sliding block 3 is provided with a top forming cavity, the rear side of the lower connecting block 2 is connected to the lateral pull block 1, the upper end face of the lower connecting block 2 is provided with a downward sliding surface 4 that slopes downward towards the front, and the lower end face of the upper sliding block 3 is provided with an upper sliding surface 5 that cooperates with the downward sliding surface 4. The upper sliding surface 5 and the downward sliding surface 4 are slidably connected. By pulling the lateral pull block 1, the lower connecting block 2 moves backward while the upper sliding block 3 moves downward.
[0015] Furthermore, the upper sliding block 3 has a lower holding hole 6 on its rear side with the same inclination angle as the lower sliding surface 4, and the lateral pull block 1 has an upper holding hole 7 on its front side with the same inclination angle as the lower holding hole 6. The lower holding hole 6 and the upper holding hole 7 are built into the push spring 8, and the upper sliding block 3 is assisted to move downward by pushing the spring 8.
[0016] Furthermore, the upper sliding surface 5 of the upper sliding block 3 is provided with a sliding insert 9, and the side of the sliding insert 9 is provided with a sliding protrusion 10. The lower connecting block 2 is provided with a sliding insertion hole 11 that cooperates with the sliding insert 9. The side of the sliding insertion hole 11 is provided with a sliding groove 12 that cooperates with the sliding protrusion 10. The sliding protrusion 10 and the sliding groove 12 are slidably connected.
[0017] Furthermore, the rear side of the lateral pull block 1 is provided with a shovel contact surface 13, which is positioned to cooperate with the shovel chicken 14, thereby driving the lateral pull block 1 to further engage.
[0018] In use, the bidirectional demolding slider mechanism for the grooved product 17 is installed on a mold. The mold includes an upper mold 15 and a lower mold 16. The lower mold 16 has a lateral forming groove on its side for mounting the bidirectional demolding slider mechanism for the grooved product 17. The lower end face of the upper mold 15, the upper end face of the lower mold 16, and the side of the lateral forming groove of the lower mold 16 are each provided with a forming cavity. The forming cavities on the lower end face of the upper mold 15, the upper end face of the lower mold 16, and the side of the lateral forming groove of the lower mold 16, together with the lateral forming cavities on the front sides of the lower connecting block 2 and the upper sliding block 3, and the top forming cavity on the upper end face of the upper sliding block 3, form the product injection cavity. After injection molding is completed, the product injection cavity is formed. After demolding, the upper template moves upward to demold, and the lateral cylinder pulls the lower connecting block 2 backward. During the backward movement of the lower connecting block 2, the upper sliding block 3 slides downward along the upper sliding surface 5 and the lower sliding surface 4 with the assistance of the pushing spring 8. After the protrusion on the upper sliding block 3 disengages from the groove of the molded product, the lower sliding block and the lower connecting block 2 move backward as a whole, thereby realizing the lateral demolding of the product. Then, through the ejector pin hole provided on the lower mold 16 in the prior art, the ejector pin pushes the molded product 17 upward, thereby completing the demolding of the product. Due to the above structure, this utility model has the advantages of simple structure, good demolding effect, high demolding efficiency, and bidirectional demolding.
