Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for a coffee machine handle. Background Technology

[0002] Currently, coffee machines with funnels are available on the market. These funnels have handles, typically cylindrical with a tapered front and wider back, designed for ergonomic comfort and easy grip. The front of the handle connects to the metal funnel, usually via a threaded connection. Since operating these coffee machines requires rotating and bending the handle, the connection between the handle and the funnel needs to be strong and stable. Therefore, a cavity is created in the middle of the handle, with a threaded bolt (or screw) of a certain length threaded into it. The front of the bolt connects to the threaded metal funnel, thus strengthening the connection between the handle and the funnel. Because the handle is quite large, if it were entirely made of metal, it would be too heavy.

[0003] In view of the above problems, this application designs an injection mold for a coffee machine handle, which can use a screw as the central skeleton of the handle and injection mold a plastic handle onto the outer wall of the screw, such as... Figure 1 As shown, the screw and the plastic handle are fixedly connected as one piece. This type of coffee machine handle ensures both strength and aesthetics while being lightweight, making it convenient to use. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for a coffee machine handle, which has a simple and reasonable structure, stable and reliable operation, and can efficiently injection mold a coffee machine handle with a screw mandrel in the middle, and can be quickly demolded.

The lower clamping block is located inside the lower forming mold cavity, and the upper clamping block is located inside the upper forming mold cavity. The upper end of the lower clamping block has an arc-shaped groove, and the lower end of the upper clamping block has an arc-shaped groove. The lower and upper clamping blocks work together to clamp the screw, causing the screw to float in the handle mold cavity. That is, the screw does not touch the inner wall of either the lower or upper forming mold cavity, and is located at the axis of the handle mold cavity. The two arc-shaped grooves are joined together to form a cylindrical cavity, the diameter of which is adapted to the outer diameter of the screw. When the upper mold is closed on the lower mold, the upper and lower clamping blocks clamp the upper and lower outer walls of the screw, respectively, and the screw is horizontally positioned.

[0014] The upper end of the upper mold assembly is provided with a hot nozzle socket, which is connected to the injection molding channel.

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1-9 As shown, an injection mold for a coffee machine handle includes a lower base 1, an upper top seat 2, a lower mold assembly 3, an upper mold assembly 4, a screw positioning assembly, and a demolding assembly 6;

[0031] Since the mold of this application requires the screw 7 to be placed inside the mold cavity, this application is generally placed vertically in the injection molding machine to facilitate the pre-fixation of the screw.

[0032] The lower base 1 includes a lower base plate 11, a suspended pad 12, and guide rods 13; the lower base plate 11 is vertically arranged, and the upper side of the lower base plate 11 is connected to the vertically arranged suspended pad 12, which consists of two suspended pads arranged opposite each other at intervals; two guide rods 13 are vertically arranged on the upper side of the suspended pad 12.

[0033] The upper side of the lower base 1 is fixed with a vertically arranged demolding component 6; the upper end face of the suspended pad 12 is connected to the lower mold component 3;

[0034] The demolding assembly 6 includes a cylinder (not shown in the figure), demolding ejector pins 62, guide pillars 63, and a pusher seat 64; the cylinder is vertically fixed on the lower base 1, and its output shaft is connected to the horizontally arranged pusher seat 64; the upper surface of the pusher seat 64 is vertically provided with a plurality of demolding ejector pins 62. The upper surface of the pusher seat 64 is also vertically provided with four guide pillars 63.

[0035] The lower mold assembly 3 includes a lower mold base 31 and a lower mold 32; the lower mold base 31 is horizontally arranged and is a square plate with a cavity 33 on its upper end surface; the lower mold 32 is embedded in the cavity 33. The lower mold 32 is provided with a plurality of lower forming cavities 8; the lower forming cavities 8 are connected to the injection molding channel 10.

[0036] The upper mold assembly 4 includes an upper mold base 41 and an upper mold 42. The upper mold base 41 is horizontally arranged, and its lower end face has a second cavity 43, within which the upper mold 42 is tightly fitted. The lower end face of the upper mold 42 has several upper forming cavities 9. The upper forming cavities 9 and lower forming cavities 8 are joined together to form a handle-shaped handle cavity 100. That is, the shape of the cavity formed by the lower forming cavities 8 and the upper forming cavities 9 is the external structure of the coffee machine handle 200. The upper end of the ejector pin 62 can be inserted into the lower forming cavity 8 and is slidably connected to the lower forming cavity 8.

[0037] The screw positioning assembly includes a lower clamping block 51 and an upper clamping block 52. The lower clamping block 51 is located inside the lower forming mold cavity 8, and the upper clamping block 52 is located inside the upper forming mold cavity 9. The upper end of the lower clamping block 51 has an arc-shaped groove, and the lower end of the upper clamping block 52 has an arc-shaped groove. The lower clamping block 51 and the upper clamping block 52 work together to clamp the screw 7, so that the screw 7 floats in the handle mold cavity 100, that is, the screw does not touch the inner wall of the lower forming mold cavity 8, nor does it touch the inner wall of the upper forming mold cavity, and it is located at the axis of the handle mold cavity 100.

[0041] Preferably, the upper mold assembly 4 further includes four sliding sleeves 46, with a guide cavity in the middle of each sliding sleeve 46; the guide rod 13 is inserted into the guide cavity.

[0042] Briefly describe its demolding process:

[0043] During demolding, the upper ejector and upper mold assembly move upward, separating the upper mold base and upper mold from the lower mold. There is no limiting force on the upper side of the molding handle 200 (the molding handle is stuck to the lower mold because the injection runner is on the lower mold). At this time, the cylinder moves to push the demolding ejector pin, which moves upward and pushes the molding handle 200 out of the lower molding cavity, completing the demolding.

[0044] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
